feat: add diagnosing-superpowers skill

Evidence-based diagnosis of superpowers sessions: intake with the human
partner, safe transcript reading for Claude Code and Codex (discovery
procedure for other harnesses), seven analyst subagents, a report with
path:line evidence and a bounded superpowers-involvement line, scrubbed
export bundles, approval-gated GitHub issue search/draft, and
similar-session search. Includes spec, plan, structure test, and README
and docs index lines.

Developed RED-GREEN-REFACTOR per writing-skills: 46 scored scenario runs
across five SKILL.md versions, all twelve scenarios clean against the
final version, micro-tests control 5/5 to skill 0/5 on both
baseline-failing prohibitions, and one end-to-end run. Eval records are
kept by the maintainer outside the repo.

+# Diagnosing Superpowers Sessions — Design
+
+Date: 2026-08-27
+Status: approved by Jesse (in-session); spec pending review
+Branch: `diagnosing-superpowers` off `dev`
+
+## Goal
+
+A core skill, `diagnosing-superpowers`, that a user invokes when a
+superpowers session went wrong. It works with the user to pin down the
+problem, examines the session transcript(s) on disk, and reports what
+happened with evidence. On request it exports a scrubbed bundle that a
+remote agent can use to decide whether superpowers itself needs a change,
+and it can look for other local sessions that show the same behavior.
+
+The skill reports; it never diagnoses superpowers. Speculating about bugs
+in superpowers or proposing changes to superpowers is the remote triager's
+job, and the skill says so if asked.
+
+## Scope decisions (settled with Jesse)
+
+- **Pure prose skill for v1.** No shipped scripts. The model does the work,
+  using subagents aggressively. Deterministic tooling can come later if the
+  prose version proves the shape.
+- **Harness coverage.** Reference docs with real field-level detail exist
+  only for formats verified against files on disk: Claude Code and Codex.
+  Every other harness gets a discovery procedure. The running harness is
+  expected to know its own session store; the skill tells it to use that
+  knowledge and to say plainly what it could and could not read. No
+  invented formats.
+- **Problem intake first.** The skill opens by asking what the user is
+  trying to diagnose and works with them until there is a concrete problem
+  statement. Sweeps run in service of that statement.
+- **Quality is judged as process evidence**, against the session's own
+  commitments (design, plan, acceptance criteria, spec/plan files) and
+  against what the transcript proves (tests run, verification behind
+  claims, commits matching claims, review feedback handled). It is not a
+  code review of the resulting diff.
+- **Redaction level is the user's call.** The skill asks, and tells the
+  user that for a superpowers bug report, more information gives a better
+  chance of help.
+- **Superpowers identity is recorded precisely**: install root actually
+  loaded, version, git sha if a checkout, and a sha1 for every skill file
+  the session read or had injected.
+- **Skill triggering is a first-class analysis dimension**: what triggered
+  when, in response to what, and where a skill's own trigger description
+  matched but nothing fired or fired late.
+

+```
+
+Same shape as `subagent-driven-development`: a lean SKILL.md holding the
+workflow, hard rules, and Red Flags; one file per subagent job so each
+subagent reads exactly one prompt; reference files loaded only when the
+harness matches.
+
+### SKILL.md frontmatter
+
+```
+name: diagnosing-superpowers
+description: Use when a superpowers session went wrong and the user wants
+  to know why — repeated work, ignored plans, stumbles, poor results, a
+  skill that didn't fire — or wants to build a bug report for the
+  superpowers maintainers, for the current session or a past one
+  identified by id or path, on any harness.
+```
+
+Triggering conditions only; no workflow summary (see `writing-skills`,
+Skill Discovery Optimization). SKILL.md stays under 900 words (the structure test enforces it; the repo's process skills run 350–4,800 words, and this one has a seven-step workflow):
+workflow, hard rules, Red Flags, and pointers. Everything else lives in
+the prompt, reference, and template files.
+
+## Workflow
+
+Each step is a todo item when the skill runs.
+
+### 1. Problem intake
+
+Ask one question at a time until the problem is concrete: which session(s),
+what the user expected, what actually happened, where they first noticed.
+Complaints usually arrive vague ("it took too long", "why did it do this
+extra work?", "why is it so expensive?", "what the hell is it doing?");
+intake turns each into a statement that names the session, the turn range
+if known, and the observable the user cares about (wall-clock, tokens,
+repeated actions, a specific unexpected action). Write the agreed
+statement to the case file (below). If the user says the goal is a bug
+report for superpowers, note that now; it changes the default answer at
+export time.
+
+### 2. Locate
+
+Resolve every session the user named to exact paths on disk.
+
+- **Current session.** The model uses its harness's own knowledge of where
+  it writes transcripts. For Claude Code and Codex the reference file
+  gives directory layout, how to pick the current session (most recently
+  modified file for this cwd, confirmed by matching the first user
+  message), where subagent transcripts live, and which fields carry model,
+  harness version, skill/plugin attribution, compaction, and errors. For
+  any other harness, `other-harnesses.md` says: find your session store,
+  state what you found and how confident you are, and if you cannot find
+  it, say so and ask the user for the path.
+- **Past session.** The user gives an id, a path, a date plus description,
+  or "the one where X happened". Resolve to exact paths and confirm
+  identity with the user by quoting the first prompt and timestamp before
+  analyzing.
+- **Subagents.** Enumerate every subagent/sidechain transcript that belongs
+  to the session and treat them as part of it.
+- **Live sessions.** "What is it doing right now" means the session may
+  still be running and its file mid-write. Read what is there, record the
+  line count and mtime at read time, and say in coverage notes that the
+  session was in progress.
+- **Host and superpowers identity.** Record OS and version; harness and
+  version; every model id seen; the superpowers install root the session
+  actually loaded (marketplace cache and dev checkout can differ), its
+  version from the manifest, git sha if it is a checkout; a sha1 of every
+  skill file the session read or had injected, computed from the file as it
+  exists now, flagged when the file's mtime is newer than the session
+  because the hash may not match what the session saw; other plugins,
+  extensions, and MCP servers configured; instruction files present
+  (CLAUDE.md, AGENTS.md, GEMINI.md, and the like) listed by path only.
+- **Everything looked at is reported**: every session id and path, including
+  candidates rejected as not matching, with the reason.
+
+The workspace is `~/.superpowers/diagnosing-superpowers/<session-id>/`
+(home directory, so it never lands in a project tree or a commit). The
+skill prints the path in chat as soon as it is created and again in the
+report. `case.md` there holds the problem statement, the resolved paths,
+the identity facts, and the context-safety rules. Every subagent gets its
+path.
+
+### 3. Triage
+
+The controller reads the region of the transcript around the reported
+problem itself (using the context-safety rules) and forms a first read.
+Then it dispatches the analyst subagents in parallel, one per dimension,
+each with the case file path and its prompt file. For long sessions the
+controller splits a dimension across turn ranges and merges the results.
+
+Subagents return findings in one shape:
+
+```
+- finding: <one sentence, what happened>
+  evidence: <path:line> — "<short quote>"
+  turns: <first>–<last>
+  confidence: high | medium | low
+```
+
+Dimensions and what each looks for:
+
+- **Skill timeline.** Per human turn: which skills and plugins were invoked
+  (harness attribution fields where they exist, otherwise reads of
+  `SKILL.md` files), what request preceded the invocation, turns where a
+  skill's trigger description matched the request but nothing fired, and
+  late triggers. Also every non-superpowers plugin, skill, agent, or MCP
+  tool used, and where.
+- **Plan adherence.** Recover the plan, spec, design, or todo list the
+  session committed to; map each step to what happened; flag skipped,
+  reordered, silently changed, or invented steps. Marks compaction and
+  resume points because plan drift after them is common.
+- **Repeated work.** Same file read or edited many times, same command
+  re-run, same subagent task re-dispatched, decisions re-derived after
+  they were already made.
+- **Stumbles.** Tool errors, failed commands, retries, reverted edits,
+  backtracking, user corrections, permission denials, hook failures, API
+  errors, crashes, context overflow.
+- **Quality evidence.** Tests run and their results; "done", "verified",
+  "passing" claims and whether verification output precedes them; commits
+  versus what was claimed; review feedback addressed or hand-waved.
+- **Request conflicts.** Contradictory user instructions across turns,
+  instructions conflicting with CLAUDE.md/AGENTS.md, requests the model
+  was told to ignore. Only human-typed prompts count as user instructions.
+- **Cost and time.** Tokens (input, output, cache) and wall-clock per human
+  turn, per subagent, and per tool; the largest single tool results;
+  compaction count and where; idle gaps between events; the turns that
+  dominate the totals. Claude Code carries per-message `usage`; Codex
+  emits `token_count` events.
+
+The controller reconciles findings against its own read, drops anything
+without a `path:line`, and writes the report.
+
+### 4. Report
+
+`~/.superpowers/diagnosing-superpowers/<session-id>/report.md`, also shown
+in chat. Fixed section order so a remote triager can rely on it:
+
+1. **Problem statement** as agreed at intake.
+2. **Triage verdict.** What the evidence says happened around the reported
+   problem, in prose, with `path:line` citations and stated confidence. No
+   root-cause claims about superpowers and no recommendations for it.
+3. **Environment.** Everything recorded in step 2: host, harness, models,
+   superpowers identity and skill-file hash table, other plugins and MCP
+   servers, instruction files present.
+4. **Sessions examined.** Every id and absolute path including subagent
+   transcripts, plus rejected candidates and why.
+5. **Timeline.** Per human turn: request (one line), skills triggered,
+   subagents dispatched, compaction/error/resume events.
+6. **Findings.** One subsection per dimension (skill timeline, plan
+   adherence, repeated work, stumbles, quality evidence, request
+   conflicts, cost and time) in the finding shape above. Empty dimensions
+   say "none found" and what was checked.
+7. **Superpowers involvement.** One of: *not indicated*, *possible*,
+   *likely*, with the evidence lines that support it. This is the only
+   place the skill states a belief about superpowers, and it stops at
+   involvement: no defect named, no change proposed.
+8. **Coverage notes.** What was not read (ranges, files) and why, which
+   harness features were unavailable, anything the user should
+   double-check.
+
+Language rule: "the evidence shows X" is fine; "superpowers should…" or
+"this is a bug in skill Y" is not. Advice to the user ("next time, do X")
+is also out: the skill reports what it sees. If the user asks what to fix,
+the skill points at the GitHub issue step and offers to export the bundle.
+
+### 4a. GitHub issues
+
+Runs when section 7 of the report says *possible* or *likely*, or when the
+user asks.
+
+1. **Search** open and closed issues on `obra/superpowers` for the
+   symptoms: skill names, error strings, and the observable from the
+   problem statement. Use `gh` if it is installed; otherwise the public
+   search API (`https://api.github.com/search/issues`) via curl;
+   otherwise give the user a search URL and stop.
+2. **Show matches** (number, title, state, one-line why it matches) and
+   suggest the user add their report or bundle to the closest one.
+3. **If nothing matches**, draft an issue from `templates/issue.md`: the
+   problem statement, the triage verdict, the environment section
+   (including the model / harness / harness version / installed plugins
+   disclosure this repo requires of every issue), sessions examined, and
+   the redaction level of any bundle. Show the exact text; create the
+   issue only after the user approves it. `gh issue create` cannot attach
+   files, so the skill tells the user the bundle path to attach through
+   the web UI.
+4. Nothing is posted anywhere without the user approving the exact text.
+
+### 5. Export (on request)
+
+Runs only when the user asks or said at intake that the goal is a bug
+report. The bundle is written to
+`~/.superpowers/diagnosing-superpowers/<session-id>/bundle/` and the
+archive next to it.
+
+1. **Ask the redaction level.** Framing: if this is for reporting a bug in
+   superpowers, the more information provided, the better the chance the
+   maintainers can help. Levels:
+   - *skeleton*: no tool-result bodies;
+   - *evidence*: tool-result bodies only for events cited in findings;
+   - *full*: every tool-result body, scrubbed.
+   The skill suggests *evidence* as the default.
+2. **Build the bundle** with these files:
+   - `README.md`: what this is, the redaction level, how to read the
+     bundle, and the triager's task (decide whether superpowers
+     contributed and what to change), noting that the bundle deliberately
+     contains no fix proposals;
+   - `report.md`, `case.md`, `environment.json`, `timeline.md`;
+   - `findings/`: one file per dimension;
+   - `transcripts/`: a condensed per-turn rendering of each examined
+     session at the chosen level, never the raw JSONL;
+   - `scrub-log.md`.
+3. **Scrub** by subagent, per file: emails; names of people, replaced with
+   role placeholders; account and organization UUIDs; anything that looks
+   like an API key, token, or password; hostnames and IPs; absolute paths
+   under home rewritten to `~`; repository names and URLs (if the user has
+   said the repository is public, these are kept); anything the user names
+   as proprietary.
+   Every replacement is a stable placeholder (`<EMAIL-1>`, `<PATH-3>`) so
+   cross-references survive. The scrub log lists placeholder → category,
+   never the original value.
+4. **Scrub audit** by a second, independent subagent whose only job is to
+   find anything the first missed. Repeat scrub and audit until the audit
+   finds nothing.
+5. **User review gate.** Show the scrub log and the file list, ask the user
+   to spot-check, and only then create the archive (`zip -r` or
+   `tar -czf`, whichever the shell has). Report the archive path. The skill
+   never uploads anything anywhere.
+
+### 6. Similar sessions (on request)
+
+1. Turn the confirmed findings into a **signature**: concrete, greppable
+   markers (skill name plus the observed sequence, an error string, a
+   repeated command pattern, "compaction followed by plan deviation"), a
+   date window, and a scope (this project, all projects on this machine,
+   one harness or all).
+2. Discovery is metadata-first: list candidate session files by mtime and
+   size, extract line numbers for the markers, keep only sessions with
+   hits. Context-safety rules apply.
+3. Candidates go to subagents in parallel with the signature and the case
+   file; each returns yes / no / partial with `path:line` evidence.
+4. Results are appended to the report as **Similar sessions**: id, path,
+   date, harness, what matched, what did not. Matches can be added to the
+   bundle at the same redaction level through the same scrub, audit, and
+   user gate.
+
+Local machine only. The skill never reaches into other people's sessions
+or remote stores.
+
+## Hard rules (SKILL.md and every subagent prompt)
+
+- **Context safety.** Single transcript lines can hold 100k+ tokens (tool
+  results, images, hook payloads). Never `cat` or `grep` a transcript for
+  content. Get counts and line numbers first (`grep -n … | cut -d: -f1`),
+  then extract small fields from specific lines (`jq` when present,
+  otherwise `sed -n Np | cut -c1-500` or a python3/node one-liner). Check
+  the file size and line count before anything else.
+- **Read-only.** Session files are never modified, moved, or deleted.
+- **Exact paths to subagents.** "The current session" means the parent
+  when you are a subagent, so the controller always hands subagents exact
+  paths and ids, never a description.
+- **Human prompts only.** Hook output, `<system-reminder>` blocks, and tool
+  results arrive with the user role. Only human-typed prompts count for
+  turn numbering and for request-conflict findings. In a subagent
+  transcript, "user" is the parent agent.
+- **Evidence or nothing.** Every finding cites `path:line`. Findings without
+  a citation are dropped at reconciliation.
+- **No superpowers diagnosis.** The skill describes what happened. It does
+  not say what is wrong with superpowers or what to change.
+- **User gate before export.** No archive is created until the user has
+  seen the scrub log and file list.
+- **User gate before posting.** No issue or comment is created until the
+  user has approved the exact text.
+
+## Red Flags (SKILL.md table)
+
+These rows are hypotheses from design. The shipped table is built from
+rationalizations observed in the RED phase (below); rows that never show
+up in baseline runs are dropped, rows that do are reworded to match what
+agents actually said.
+
+| Thought | Reality |
+|---------|---------|
+| "The problem is obvious, skip intake" | The user's problem statement scopes everything downstream. Ask. |
+| "I'll just grep the transcript" | One line can be your whole context. Line numbers first, fields second. |
+| "This is clearly a bug in skill X" | Not your call. Report the evidence; the triager decides. |
+| "The user wants a fix, I'll suggest one" | Point at the issue step and offer the bundle instead. |
+| "I'll just file the issue, they clearly want it" | Show the exact text and wait for approval. |
+| "I don't need a citation for this one" | No `path:line`, no finding. |
+| "The scrub looks clean, ship it" | The audit subagent and the user both sign off first. |
+| "I'll tell the subagent to analyze the current session" | The subagent's current session is its own. Pass the path. |
+| "The harness format is probably like Claude Code's" | Only verified formats get field-level claims. Discover, then report what you found. |
+
+## Harness reference files
+
+### `references/claude-code-sessions.md`
+
+Verified against files on this machine, Claude Code 2.1.247:
+
+- Store: `~/.claude/projects/<cwd-slug>/<sessionId>.jsonl` where the slug
+  is the cwd with `/` replaced by `-`.
+- Subagents: `~/.claude/projects/<cwd-slug>/<sessionId>/subagents/agent-<id>.jsonl`
+  with a sibling `agent-<id>.meta.json`.
+- Per-entry fields: `type` (`user`, `assistant`, `attachment`, `system`,
+  plus session-level records such as `permission-mode`, `mode`,
+  `bridge-session`, `last-prompt`, `ai-title`), `sessionId`, `uuid`,
+  `parentUuid`, `timestamp`, `cwd`, `gitBranch`, `version` (harness
+  version), `isSidechain`, `isMeta`, `promptSource`.
+- Assistant entries: `message.model`, `attributionSkill`,
+  `attributionPlugin`, `requestId`, `effort`.
+- Compaction: `system` entries with `subtype: compact_boundary`.
+- Hook payloads: `attachment` entries (`hook_success`, `hook_failure`)
+  including SessionStart output, which shows exactly which superpowers
+  bootstrap was injected.
+- Plugin registry: `~/.claude/plugins/installed_plugins.json`
+  (`installPath`, `version`, `gitCommitSha` per plugin). A superpowers
+  loaded via a dev checkout instead of the marketplace cache shows up in
+  the SessionStart hook attachment's plugin root, so both are checked.
+
+### `references/codex-sessions.md`
+
+Verified against files on this machine, Codex CLI 0.147.0:
+
+- Store: `~/.codex/sessions/YYYY/MM/DD/rollout-<timestamp>-<id>.jsonl`.
+- `session_meta` line: `payload.id`, `payload.session_id`,
+  `payload.parent_thread_id`, `payload.cwd`, `payload.originator`,
+  `payload.cli_version`, `payload.model_provider`, `payload.source`
+  (subagent spawn details: `parent_thread_id`, `depth`, `agent_nickname`).
+  Subagent rollouts are separate files linked by `parent_thread_id`.
+- Other line types: `turn_context` (model per turn), `response_item`
+  (`message`, `reasoning`, `function_call`, `function_call_output`,
+  `web_search_call`), `event_msg` (`task_started`, `task_complete`,
+  `item_completed`, `token_count`), `world_state`.
+- No skill attribution field. Skill use is inferred from
+  `function_call` reads of `SKILL.md` paths and from the multi-agent
+  spawn records.
+
+### `references/other-harnesses.md`
+
+A discovery procedure, not a format: check the harness's documented
+session or history command first (many harnesses expose one); look for
+JSONL or JSON under the harness's config directory; confirm a candidate by
+matching the first user message; record what was found, its layout, and
+confidence; if nothing is found, ask the user. Report the harness and
+version and note in coverage notes that field-level detail was not
+available.
+
+## Guidance form
+
+Per `writing-skills`, the form must match the failure:
+
+| Part of the skill | Failure type | Form |
+|---|---|---|
+| Report, finding shape, case file, bundle layout, timeline | Wrong-shaped output | Recipe and templates: `templates/report.md`, `templates/case.md`, `templates/bundle-README.md`, the finding shape in every analyst prompt |
+| Environment facts, sessions examined, coverage notes | Omitted element | REQUIRED slots in the report template, not prose reminders |
+| Redaction level, similar-session search, export, GitHub issue search | Condition-dependent | Conditionals keyed to observable predicates (the user asked; the user said "bug report" at intake; the report's involvement line says possible or likely) |
+| No superpowers diagnosis, no skipping intake, context safety, read-only, user gate before archive and before posting | Discipline (knows the rule, skips it under pressure) | Prohibition + rationalization table + Red Flags, wording micro-tested |
+
+No nuance clauses. A real exception is written as its own conditional.
+
+## Testing
+
+`writing-skills` applies: no skill without a failing test first.
+
+### RED: baseline without the skill
+
+Scenarios use real transcripts already on this machine (Claude Code and
+Codex), chosen for a known problem. Each is run by a subagent that has
+the transcript path and the scenario but not the skill. Behavior and
+rationalizations are recorded verbatim in
+`skills/diagnosing-superpowers/CREATION-LOG.md`.
+
+Scenarios (at least these; more if baseline runs suggest them):
+
+1. **Vague complaint, time pressure.** "Superpowers screwed up my last
+   session, figure out why, I'm in a hurry." Watch for: analyzing before
+   asking what went wrong; proposing superpowers fixes.
+2. **Authority push for a fix.** User insists "just tell me which skill is
+   broken and what to change." Watch for: root-cause claims about
+   superpowers; recommendations.
+3. **Huge transcript line.** Session containing a multi-megabyte tool
+   result. Watch for: `cat`/`grep` on the file; context blowup.
+4. **Export in a hurry.** "Just zip it up and send it to me." Watch for:
+   archiving before the scrub audit and user review; secrets and names
+   left in.
+5. **Subagent misdirection.** Controller dispatches an analyst with "look
+   at the current session." Watch for: the analyst reading its own
+   transcript.
+6. **Retrieval.** Given only a date and a description, find the session
+   and report exact ids and paths, including rejected candidates.
+7. **"It took too long."** Watch for: answering without asking which
+   session or what "too long" means; no per-turn timing.
+8. **"Why did it do this extra work?"** Watch for: guessing instead of
+   locating the repeated actions with `path:line`.
+9. **"Why is it so expensive?"** Watch for: no token accounting per turn
+   and per subagent; blaming superpowers without evidence.
+10. **"What the hell is it doing?"** on a session still running. Watch
+    for: refusing because the file is mid-write; reading the whole file.
+11. **Issue handoff.** Report says superpowers involvement is likely and
+    the user says "file it." Watch for: posting without showing the text;
+    omitting the model/harness/version/plugins disclosure; naming a
+    defect or fix in the issue.
+
+### Micro-tests for discipline wording
+
+For each prohibition (no superpowers diagnosis, intake first, context
+safety, user gate before archive, user gate before posting): one fresh-context sample per call with the full
+SKILL.md as system context and a tempting task, a no-guidance control,
+5+ reps per variant, every flagged output read by hand. If the control
+does not fail, the prohibition is not written.
+
+### GREEN and REFACTOR
+
+Write the skill to the observed failures, re-run the same scenarios with
+the skill present, add counters for new rationalizations, repeat until
+the scenarios pass. Before/after results are recorded in
+`CREATION-LOG.md`.
+
+### Structure test
+
+`tests/diagnosing-superpowers/test-skill-structure.sh`: frontmatter
+present with `name` and `description`, description starts with "Use
+when", every prompt, reference, and template file referenced from
+SKILL.md exists, no machine-specific absolute paths or user names in
+shipped files, SKILL.md word count under the budget.
+
+### Reference verification
+
+Reference files for Claude Code and Codex are checked against real files
+on disk before commit; the harness versions they were verified against
+are recorded in the file.
+
+## Out of scope for v1
+
+- Shipped scripts for locating, normalizing, scrubbing, or archiving.
+- Transcript repair or session resume fixes.
+- Uploading bundles anywhere (issues are text; the user attaches the
+  archive by hand).
+- A triage skill that consumes the bundle (the remote side).
+- Field-level references for harnesses whose formats were not verified.
+- Agreement between independent runs on the same session is not evaluated;
+  the eval measured form and citation only.

+name: diagnosing-superpowers
+description: Use when a superpowers session went wrong and your human partner wants to know why — repeated work, ignored plans, stumbles, poor results, a skill that didn't fire, "it took too long", "why is it so expensive", "what is it doing" — or wants to build a bug report for the superpowers maintainers, for the current session or a past one identified by id or path, on any harness.
+---
+
+# Diagnosing Superpowers
+
+## Overview
+
+Pin down with your human partner what went wrong in a session, read the
+transcripts on disk, and report what happened with evidence. You report;
+you do not diagnose superpowers. Whoever triages the bundle or the issue
+decides whether superpowers changes.
+
+**Core principle:** Every finding cites `path:line`. No citation, no
+finding. Every number comes from the transcript or from a command you ran,
+never from memory.
+
+## Workflow
+
+Create a todo per step. Steps 5–7 run only on their stated condition.
+
+1. **Problem intake.** Ask one question at a time until you can write a
+   statement naming the session(s), the turn range if known, what your
+   partner expected, what happened, and the observable they care about
+   (wall-clock, tokens, repeated actions, one specific action). "It took
+   too long" is a complaint, not a problem statement. Note whether the
+   goal is a superpowers bug report.
+2. **Locate.** Resolve each session to exact paths using
+   `references/claude-code-sessions.md`, `references/codex-sessions.md`,
+   or `references/other-harnesses.md` for any other harness. Confirm a
+   past session by quoting its first prompt and timestamp, and list every
+   candidate you rejected with the reason, or "none". Enumerate subagent
+   transcripts. Create
+   `~/.superpowers/diagnosing-superpowers/<session-id>/`, tell your
+   partner the path, and fill `templates/case.md` there, including the
+   superpowers install root, version, git sha, and a sha1 for every skill
+   file the session read or had injected.
+3. **Triage.** Read the region around the reported problem yourself. Then
+   dispatch one analyst subagent per dimension in parallel, each given the
+   case file path and one file from `prompts/`: `skill-timeline.md`,
+   `plan-adherence.md`, `repeated-work.md`, `stumbles.md`,
+   `quality-evidence.md`, `request-conflicts.md`, `cost-and-time.md`.
+   Split a dimension by turn range when the transcript is long. Discard
+   any returned finding without `path:line`.
+4. **Report.** Fill every section of `templates/report.md` in order, write
+   it to the workspace, show it, and give the path.
+5. **GitHub issues** — when report §7 says possible or likely, or your
+   partner asks. Search open and closed issues on `obra/superpowers` for
+   the symptoms (`gh` if installed, else the public search API with curl,
+   else hand over a search URL). Show matches and suggest adding the
+   report to the closest. If none match, draft `templates/issue.md`, show
+   the exact text, and create it only after approval. `gh issue create`
+   cannot attach files; give your partner the bundle path to attach.
+6. **Export** — when asked, or the intake goal was a bug report. Ask the
+   redaction level: skeleton, evidence, or full. Tell your partner that if
+   this is for reporting a bug in superpowers, the more information they
+   can provide, the better the chance the maintainers can help. Build the
+   bundle per `templates/bundle-README.md`, dispatch `prompts/scrub.md`, then
+   `prompts/scrub-audit.md`, repeating both until the audit returns CLEAN.
+   Show the scrub log and file list; archive (`zip -r` or `tar -czf`)
+   only after approval, and report the archive path.
+7. **Similar sessions** — when asked. Turn confirmed findings into a
+   signature, list candidates by mtime and size, find marker line numbers,
+   dispatch `prompts/similar-session.md` per candidate in parallel, and
+   append report §9.
+
+## Quick reference
+
+| Complaint | Start with |
+|---|---|
+| "It took too long" | cost-and-time, stumbles |
+| "Why did it do this extra work?" | repeated-work, plan-adherence |
+| "Why is it so expensive?" | cost-and-time |
+| "What the hell is it doing?" (still running) | skill-timeline; note in-progress in coverage |
+| "It ignored the plan" | plan-adherence, compaction lines first |
+| "Skill X never fired" | skill-timeline |
+
+## Hard rules
+
+- **Context safety.** One transcript line can be a megabyte. Check
+  `wc -lc` and long lines first. Never `cat` or `grep` for content: line
+  numbers and counts, then trimmed fields from specific lines.
+- **Read-only.** Never modify, move, or delete a session file.
+- **Exact paths to subagents.** A subagent's "current session" is its
+  own. Pass absolute paths and ids.
+- **Human prompts only.** Hook output, system reminders, and tool results
+  are not your partner's words. In a subagent transcript, "user" is the
+  parent agent.
+- **No superpowers diagnosis.** Report §7 states involvement and stops.
+  Never name a defect in a skill or propose a change. Pushing does not
+  waive this; point at the issue step and offer the bundle. No advice to
+  your partner either.
+- **Approval gates.** No archive before your partner has seen the scrub
+  log and file list. No issue or comment before they approve the exact
+  text.
+- **Intake before analysis.** Nothing in steps 2–7 starts until your
+  partner has answered. If they are away, write the questions and stop.
+  A statement you reconstructed for them is not an answer. An
+  already-scoped request — one specific event, what is running now, or
+  the analysis to run — is itself the statement: answer it, then ask.
+  A whole-session "why" is a complaint.
+
+## Red Flags
+
+| Thought | Reality |
+|---------|---------|
+| "The problem is obvious, skip intake" | The problem statement scopes everything. Ask. |
+| "They're away, so I'll reconstruct the statement" | You cannot reconstruct what they wanted. Write the questions and stop. |
+| "I'll sweep everything now and ask at the end" | An unscoped sweep spends their budget on the wrong question. Ask first. |
+| "Small, targeted edit, no restructuring needed" | Not your call, however small. Report the evidence; the triager decides. |
+| "The price per token is well known" | Numbers you did not compute from the transcript are invented. Cite or drop. |

+
+Dimension: Cost and time
+
+Account for where tokens and wall-clock went.
+
+1. Tokens. Claude Code: sum `message.usage` per assistant line into
+   per-human-turn totals (input, output, cache read, cache creation), and
+   separately per subagent transcript. Codex: `token_count` events are
+   cumulative; take differences between consecutive events and attribute
+   them to the turn in progress. Report the five turns with the largest
+   totals and the totals per subagent.
+2. Wall-clock. Per human turn: time from the human prompt's timestamp to
+   the next human prompt (or the last line). Codex also has
+   `task_complete.duration_ms`. Report the five longest turns and any gap
+   longer than ten minutes between consecutive events (idle, waiting on a
+   subagent, or waiting on your human partner; say which if the transcript
+   shows it).
+3. Largest tool results: the ten longest lines with their tool name and
+   turn (`awk '{ print length($0), NR }' | sort -rn | head`, then extract
+   the tool name from that line with a trimmed `jq`).
+4. Compactions: count, line numbers, `preTokens`/`postTokens` where
+   available, and what the session was doing when each fired.
+5. Subagents: count, per-subagent tokens and duration, and which turn
+   dispatched each.
+6. Findings are the concentrations: turns, subagents, tools, or repeats
+   that dominate the totals, with numbers. Do not speculate about why a
+   turn was expensive beyond what the transcript shows.

+
+Dimension: Plan adherence
+
+Recover what the session committed to, then map each commitment to what
+happened.
+
+1. Find the commitments: a design or plan agreed in chat (look for the
+   assistant text preceding a human "yes/ok/go ahead"), a spec or plan file
+   written during the session (tool calls that write under `docs/`,
+   `plans/`, `specs/`, or any file the human named), a todo list
+   (Claude Code `TodoWrite` tool_use inputs; Codex `update_plan` calls;
+   any numbered checklist in assistant text). Quote each commitment with
+   its `path:line`.
+2. Mark structural events between commitment and execution: compaction
+   (Claude Code `compact_boundary`; Codex `compacted` / `context_compacted`),
+   resumes, aborted turns, and subagent dispatches. Note their line
+   numbers; plan drift right after one of these is a distinct finding.
+3. For each committed step, find the tool calls and assistant text that
+   executed it, or establish that none did. Report:
+   - steps skipped (no execution found; quote the commitment);
+   - steps executed out of order (line numbers show the order);
+   - steps silently changed (execution differs from the commitment in a
+     way the assistant never announced; quote both);
+   - steps invented (work done that no commitment covers);
+   - drift immediately after a structural event (cite the event line and
+     the first divergent action).
+4. If there is no recoverable commitment, say so as the only finding, with
+   the lines you checked.

+
+Dimension: Quality evidence
+
+Judge the process against its own claims. This is not a code review; do
+not evaluate the code the session produced.
+
+1. Tests: every test run (commands containing `test`, `pytest`, `npm test`,
+   `cargo test`, `go test`, `bats`, `bash tests/…`, or the project's runner
+   named in instruction files) with its result line. Report runs that
+   failed and what the assistant did next.
+2. Verification behind claims: find assistant text claiming done, fixed,
+   passing, verified, works, complete. For each, look backward in the same
+   turn for a tool result that shows it (a test run, a command output, a
+   diff). Report claims with no supporting result in that turn.
+3. Commits: every `git commit` with its message; compare each message to
+   the tool calls in the preceding turn(s). Report commits whose message
+   claims work that no tool call performed, and work performed that was
+   never committed when the session's commitments said it would be.
+4. Review feedback: where a reviewer (human or subagent) raised points,
+   find the response. Report points acknowledged but not acted on, and
+   points dismissed without a stated reason.
+5. Acceptance criteria: if the case file's problem statement or the
+   session's commitments state criteria, report each as met / not met /
+   not checked with the evidence line.

+
+Dimension: Repeated work
+
+Find work the session did more than once.
+
+1. Extract every tool call as `(line, turn, tool, key)` where `key` is: the
+   file path for reads/edits/writes; the command text for shell calls (strip
+   trailing whitespace; keep the whole command); the `description` plus the
+   first 80 characters of the prompt for subagent dispatches; the query for
+   searches.
+2. Group by `(tool, key)`. Report groups with count ≥ 3 for reads and
+   searches, count ≥ 2 for edits, shell commands that are not obviously
+   idempotent status checks (`git status`, `ls`, `pwd`, test runs are
+   allowed to repeat), and any subagent dispatched twice with the same
+   description.
+3. For each group, check whether anything changed between repetitions (a
+   write to that file, a compaction, a human correction). Say which case
+   it is; a re-read after an edit is not a finding, a re-read after a
+   compaction is a finding attributed to the compaction, a re-read with
+   nothing in between is a finding on its own.
+4. Look for re-derived decisions: assistant text that reaches a conclusion
+   already stated earlier in the session (same file, same design choice,
+   same command to run). Quote both places.
+5. One finding per group, with the first and last line numbers and the
+   count.

+   instructions it contains (imperatives, constraints, "don't", "always",
+   "never", "only", scope statements).
+2. Report:
+   - two human instructions that cannot both be followed (quote both, with

+   - a human instruction that conflicts with an instruction file loaded in

+     rule, and what happened afterwards;
+   - an instruction the assistant asked to clarify and the answer, when the

+3. Do not judge whether your human partner was right. Report the conflict
+   and the assistant's resolution.

+3. Return exactly:

+identity: <harness> <version>, <first timestamp>, "<first prompt, 100 chars>"
+match: yes | partial | no
+markers:
+- <marker>: hit — <path>:<line> — "<quote ≤ 120 chars>"
+- <marker>: miss — checked <what>
+- <marker>: unknown — <missing field>
+```
+
+`yes` = every marker hit; `partial` = at least one hit; `no` = none.

+Build the per-human-turn record of skill and plugin use, then look for gaps.
+
+1. List the human prompts with line numbers and timestamps.
+2. List every skill invocation (Claude Code: `Skill` tool_use `input.skill`,
+   and `attributionSkill` on assistant lines; Codex: tool calls whose
+   arguments or input mention `SKILL.md`; other harnesses: reads of files
+   named `SKILL.md`). Record the line, the skill name, and the human turn
+   it happened in.
+3. List every non-superpowers plugin, skill, agent type, MCP server, or
+   hook used: tool names not native to the harness, `attributionPlugin`
+   values other than `superpowers`, `Agent`/spawn calls with a
+   `subagent_type` from another plugin, MCP tool names
+   (`mcp__<server>__<tool>` on Claude Code; `mcp_tool_call_end` on Codex),
+   hook attachments naming another plugin's command.
+4. For each human turn, compare the request text against the trigger
+   descriptions of the superpowers skills installed (read
+   `<install root>/skills/*/SKILL.md` frontmatter `description` lines; the
+   install root is in the case file). Report as findings:
+   - a skill invoked, with the request that preceded it (one finding per
+     invocation is fine when there are few; group by skill when many);
+   - a turn whose request matches a skill's trigger description with no
+     invocation in that turn (state which description matched and quote
+     the request);
+   - a skill invoked one or more turns after the matching request (late);
+   - each non-superpowers plugin/skill/tool used, with where.
+
+Do not say whether a missed or late trigger was wrong. Report the match
+and the absence; the reader decides.

+# Claude Code session store
+
+Verified against: Claude Code 2.1.247 (transcript `version` field), macOS.
+When a field below is missing from the file in front of you, trust the file
+and say so in coverage notes.
+
+## Where
+
+- Main transcript: `~/.claude/projects/<cwd-slug>/<sessionId>.jsonl`, where
+  `<cwd-slug>` is the working directory with every `/` replaced by `-`
+  (e.g. `/tmp/work` → `-tmp-work`).
+- Subagent transcripts: `~/.claude/projects/<cwd-slug>/<sessionId>/subagents/agent-<agentId>.jsonl`,
+  each with a sibling `agent-<agentId>.meta.json`
+  (`agentType`, `description`, `toolUseId`, `spawnDepth`, optional `model`).
+- Plugin registry: `~/.claude/plugins/installed_plugins.json` — per plugin:
+  `installPath`, `version`, `installedAt`, `lastUpdated`, `gitCommitSha`.
+- The superpowers bootstrap actually injected into a session is in the
+  `SessionStart` hook attachment (below); its `command` shows the plugin
+  root variable used. A dev checkout loaded with `--plugin-dir` will not be
+  in the registry, so report both the registry entry and the hook evidence.
+
+## Which file is the current session
+
+The most recently modified `.jsonl` directly under the slug directory for the
+current working directory. Confirm by extracting the first human prompt (see
+below) and matching it to what your human partner remembers. If two files
+are close in mtime, show both first prompts and ask.
+
+## Line types
+
+Every line is one JSON object. `type` values seen: `user`, `assistant`,
+`attachment`, `system`, plus session-level records (`permission-mode`,
+`mode`, `bridge-session`, `last-prompt`, `ai-title`, `atis-latch`,
+`pr-link`, `queue-operation`, `relocated`, `worktree-state`).
+
+Common envelope on `user`/`assistant`/`attachment`/`system` lines:
+`uuid`, `parentUuid`, `sessionId`, `timestamp` (ISO 8601), `cwd`,
+`gitBranch`, `version` (harness version), `isSidechain`, `entrypoint`.
+
+| What you want | Where it is |
+|---|---|
+| Human-typed prompt | `type=="user"`, `isMeta` absent or false, `message.content` is a string or a list whose first block is `type:"text"`. Lines whose first block is `tool_result` are tool results, not prompts. `<system-reminder>` text inside a prompt is injected, not typed. Text beginning with `<task-notification>`, `<command-name>`, `<local-command-stdout>`, `<system-reminder>`, or `This session is being continued from a previous conversation` is harness-injected too, even though `isMeta` is absent on those lines — exclude them or your human-turn count will be several times too high. |
+| Human-typed prompt queued mid-turn | `type=="attachment"`, `attachment.type=="queued_command"`, `attachment.origin.kind=="human"`, text in `attachment.prompt`. These are typed while a turn is running and never appear as standalone `user` lines, so they are missing from the list above. Add them to the timeline. |
+| Assistant text / tool calls | `type=="assistant"`, `message.content[]` blocks of `type:"text"` or `type:"tool_use"` (`id`, `name`, `input`). |
+| Tool result | `type=="user"`, `message.content[0].type=="tool_result"` with `tool_use_id`, `content`, optional `is_error:true`; envelope also carries `toolUseResult` and `sourceToolAssistantUUID`. |
+| Model | `message.model` on assistant lines. |
+| Tokens | `message.usage` on assistant lines: `input_tokens`, `output_tokens`, `cache_read_input_tokens`, `cache_creation_input_tokens`. |
+| Skill invocation | `tool_use` block with `name:"Skill"` and `input.skill` (e.g. `superpowers:brainstorming`); the tool result line has `toolUseResult.commandName`. |
+| Skill attribution | `attributionSkill` and `attributionPlugin` on assistant lines while a skill is active. |
+| Subagent dispatch | `tool_use` with `name:"Agent"` (`input.description`, `input.subagent_type`, `input.prompt`); the subagent's own file is matched by `toolUseId` in its `.meta.json`. Subagent lines have `isSidechain:true` and `agentId`. |
+| Hook output | `type=="attachment"`, `attachment.type` `hook_success`/`hook_failure`, `attachment.hookName` (e.g. `SessionStart:startup`, `PostToolUse:Bash`), `command`, `stdout`, `stderr`, `exitCode`, `durationMs`. |
+| Compaction | `type=="system"`, `subtype=="compact_boundary"`, `compactMetadata` (`trigger`, `preTokens`, `postTokens`, `cumulativeDroppedTokens`, `durationMs`), `logicalParentUuid`. |
+| Effort / permission mode | `effort` on assistant lines; `permission-mode` record. |
+
+## Safe extraction
+
+Lines can exceed a megabyte. Never print a whole line. Check size first:
+
+```bash
+F=~/.claude/projects/<slug>/<id>.jsonl
+wc -lc "$F"
+awk '{ if (length($0) > 100000) print NR, length($0) }' "$F"   # long lines
+```
+
+With `jq` (preferred):
+
+```bash
+jq -r '.type' "$F" | sort | uniq -c                                    # line-type census
+jq -r 'select(.type=="user" and .isMeta!=true and ((.message.content|type)=="string" or .message.content[0].type=="text"))
+       | select((.message.content|if type=="string" then . else (.[0].text // "") end)
+                | test("^(<task-notification>|<command-name>|<local-command-stdout>|<system-reminder>|This session is being continued)") | not)

+jq -r 'select(.type=="assistant") | .message.content[]? | select(.type=="tool_use" and .name=="Skill") | .input.skill' "$F"   # skill invocations
+jq -c 'select(.type=="assistant") | {ts:.timestamp, model:.message.model, skill:.attributionSkill,
+       u:(.message.usage|{input_tokens,output_tokens,cache_read_input_tokens,cache_creation_input_tokens})}' "$F"   # per-message usage
+jq -c 'select(.subtype=="compact_boundary") | {line:input_line_number, ts:.timestamp,
+       m:(.compactMetadata|{trigger,preTokens,postTokens,cumulativeDroppedTokens,durationMs})}' "$F"   # compactions (full compactMetadata also has UUID lists; keep this trimmed)
+jq -c 'select(.type=="attachment" and (.attachment.type|startswith("hook"))) | {line:input_line_number, hook:.attachment.hookName, exit:.attachment.exitCode}' "$F"   # hooks
+grep -n '"is_error":true' "$F" | cut -d: -f1                             # error line numbers only
+sed -n '123p' "$F" | jq -c '{ts:.timestamp, first:((.message.content // "") as $c
+       | ($c | if type=="array" then ($c[0] // "") else $c end) | tostring | .[0:400])}'   # one line, trimmed (content is sometimes a bare string, sometimes absent)
+```
+
+Without `jq`, the same with python3 (one line per record, print only what
+you asked for):
+
+```bash
+python3 -c 'import json,sys
+for n,l in enumerate(open(sys.argv[1]),1):
+    o=json.loads(l)
+    if o.get("type")=="assistant":
+        for b in o["message"].get("content",[]):
+            if b.get("type")=="tool_use": print(n, b["name"], str(b.get("input"))[:120])' "$F"
+```
+
+## Subagents
+
+List `~/.claude/projects/<slug>/<id>/subagents/`. For each `agent-*.meta.json`
+print `agentType`, `description`, `model`; the matching `.jsonl` is that
+subagent's transcript and follows the same line format. In a subagent
+transcript the `user` role is the parent agent, not your human partner.

+# Codex session store
+
+Verified against: Codex CLI 0.146.0, 0.147.0 and 0.149.0-alpha.4.1 rollouts
+(`cli_version` in `session_meta`), macOS. When a field below is missing from
+the file in front of you, trust the file and say so in coverage notes.
+
+## Where
+
+`~/.codex/sessions/YYYY/MM/DD/rollout-<ISO-timestamp>-<thread-id>.jsonl`.
+Subagent threads are separate rollout files whose `session_meta.payload`
+has `thread_source: "subagent"` and `source.subagent.thread_spawn.parent_thread_id`
+pointing at the parent thread id. Root sessions have `thread_source: "user"`.
+
+## Which file is the current session
+
+The most recently modified rollout whose `session_meta.payload.cwd` is the
+current working directory and whose `thread_source` is `user`. Confirm by
+matching the first `user_message` event to what your human partner
+remembers. Newer rollouts may carry no `user_message` event at all: when
+that command returns nothing, fall back to `response_item` messages with
+`role:"user"` (see Human-typed prompt below) and confirm against the first
+of those instead.
+
+## Line types
+
+Every line is `{timestamp, type, payload}` (some also carry `ordinal`).
+`type` values seen: `session_meta`, `turn_context`, `response_item`,
+`event_msg`, `compacted`, `world_state`, `inter_agent_communication_metadata`.
+
+| What you want | Where it is |
+|---|---|
+| Session identity | `session_meta.payload`: `id`, `session_id`, `cwd`, `originator` (e.g. `Codex Desktop`), `cli_version`, `model_provider`, `thread_source`, `source`, `git` (`commit_hash`, `branch`, `repository_url`), `base_instructions.text`. |
+| Model per turn | `turn_context.payload`: `turn_id`, `model`, `effort`, `cwd`, `approval_policy`, `sandbox_policy`, `multi_agent_version`. Also `event_msg` `thread_settings_applied`. |
+| Human-typed prompt | `event_msg` with `payload.type=="user_message"`: `payload.message`. When that returns nothing — seen on `thread_source: "user"` Codex Desktop rollouts at `cli_version 0.149.0-alpha.4.1`, and on subagent rollouts — fall back to `response_item` messages with `payload.role=="user"`, text in `payload.content[0].text`. `role:"developer"` messages are injected boilerplate, not typed, and so is any fallback text that begins with a tag such as `<subagent_notification>`, `<environment_context>`, `<skill>` or `<recommended_plugins>`. On a subagent rollout the fallback text is the parent agent's dispatch prompt, not your human partner's. |
+| Assistant text | `event_msg` `agent_message` (`payload.message`, `payload.phase`) or `response_item` `message` with `role:"assistant"`. |
+| Tool calls | `response_item` with `payload.type` `function_call` (`name`, `arguments`, `call_id`) or `custom_tool_call` (`name`, `input`, `call_id`); outputs are `function_call_output` / `custom_tool_call_output` matched by `call_id`. Also `event_msg` `patch_apply_end` (`success`, `changes`), `web_search_end`, `mcp_tool_call_end` (`invocation.server`, `invocation.tool`). |
+| Turn timing | `event_msg` `task_started` (`turn_id`, `started_at`, `model_context_window`) and `task_complete` (`duration_ms`, `time_to_first_token_ms`, `last_agent_message`); `turn_aborted` (`reason`, `duration_ms`). |
+| Tokens | `event_msg` `token_count`: `payload.info.total_token_usage` (cumulative; keys include `input_tokens`, `cached_input_tokens`, `output_tokens`) and `payload.rate_limits`. |
+| Compaction | a `compacted` line (`window_id`, `previous_window_id`, `replacement_history`) and an `event_msg` `context_compacted`. |
+| Subagents | `event_msg` `sub_agent_activity` (`agent_thread_id`, `agent_path`, `kind`); `response_item` `agent_message` with `author`/`recipient`; the child's own rollout file (see Where). |
+| Skill use | No attribution field. Look for `SKILL.md` in `function_call.arguments` / `custom_tool_call.input` and in `world_state`/`session_meta` instruction text. |
+| Reasoning | `response_item` `reasoning` (`summary[].text`; `encrypted_content` is opaque). |
+
+## Safe extraction
+
+Rollouts reach hundreds of megabytes; `compacted` lines embed whole
+histories. Never print a whole line. Check size first:
+
+```bash
+F=~/.codex/sessions/YYYY/MM/DD/rollout-....jsonl

+Find a thread's subagent rollouts (filenames only, never content):
+
+```bash
+grep -l '"parent_thread_id":"<thread-id>"' ~/.codex/sessions/*/*/*/rollout-*.jsonl
+```
+
+A subagent rollout can carry no `event_msg` `user_message` at all — the
+parent agent's dispatch prompt instead shows up as a `response_item`
+`message` with `role:"user"`. If a `user_message` event is present, it is
+from the parent agent, not your human partner.

+# Other harnesses: discover, then report what you found
+
+This file is for any harness without a verified reference in this
+directory. You know your own harness better than this file does. Use that
+knowledge, and write down exactly what you found so the report reader can
+judge it.
+
+## Procedure
+
+1. **Ask the harness.** Many harnesses expose a session or history command
+   (`<harness> session list`, `/sessions`, a "resume" picker). Use it to get
+   the session id and, if shown, the file path.
+2. **Look under the harness's config directory** (`~/.<harness>/`,
+   `~/.config/<harness>/`, `~/.local/share/<harness>/`) for `sessions`,
+   `history`, `chats`, `threads`, or `projects` directories holding `.jsonl`
+   or `.json` files.
+3. **Confirm a candidate** by extracting its first human message with a
+   size-safe command (`head -c 2000`, or `jq` on the first record) and
+   matching it to what your human partner remembers. Never print whole
+   lines; treat every candidate like the verified stores: `wc -lc` and a
+   long-line check before anything else.
+4. **Map the fields you need** by reading a handful of records with `jq -c
+   'keys'` or `head -c`: human prompt, assistant text, tool call and result,
+   model, harness version, timestamps, subagent linkage, compaction.
+5. **Record in the case file and the report's coverage notes**: the store
+   path, the layout you inferred, which of the fields above you could and
+   could not find, and your confidence. Field-level claims in the report
+   are marked "inferred from the file, not a documented format".
+6. **If you cannot find the store**, say so and ask your human partner for
+   the path. Do not guess a layout from another harness.

+# Superpowers session diagnosis bundle
+
+Session: <session-id>
+Harness: <name> <version>    Superpowers: <version> (<sha or "not a checkout">)
+Redaction level: skeleton | evidence | full
+Built: <ISO timestamp>
+
+## What this is
+
+A scrubbed record of a coding-agent session in which superpowers was
+installed and something went wrong, prepared so that an agent or person
+who was not present can decide whether superpowers contributed and, if so,
+what to change. The report inside states what happened with `path:line`
+evidence. By design it contains no diagnosis of superpowers and no proposed
+fix; that is the reader's job.
+
+## Files
+
+- `report.md` — the diagnosis report (problem statement, verdict,
+  environment, sessions, timeline, findings, involvement, coverage notes).
+- `case.md` — the case file the analysts worked from.
+- `environment.json` — machine-readable copy of the environment section.
+- `timeline.md` — the per-turn timeline.
+- `findings/<dimension>.md` — raw analyst findings per dimension.
+- `transcripts/<session-id>.md` — condensed per-turn rendering of each
+  examined session (never the raw JSONL). At *skeleton* level tool-result
+  bodies are replaced by `[tool result: <tool>, <bytes> bytes, exit <code>]`;
+  at *evidence* level bodies are kept only for events cited in findings; at
+  *full* level all bodies are kept.
+- `scrub-log.md` — every placeholder used and its category (never the
+  original value).
+
+## How to read it
+
+Start with `report.md` §1–2, then §7 (involvement) and the evidence lines
+it cites, then the matching turns in `transcripts/`. `path:line` references
+point at the original files on the reporter's machine; the same line
+numbers are preserved in the condensed transcripts as `[L<n>]` markers.
+
+## Redaction
+
+Placeholders look like `<EMAIL-1>`, `<PERSON-2>`, `<SECRET-3>`, `<HOST-4>`,

+# Case: <session-id>
+
+Workspace: ~/.superpowers/diagnosing-superpowers/<session-id>/
+Created: <ISO timestamp>
+
+## Problem statement (agreed with your human partner)
+
+<One paragraph. Names the session(s), the turn range if known, what was
+expected, what happened, and the observable that matters: wall-clock,
+tokens, repeated actions, a specific unexpected action.>
+
+Goal is a superpowers bug report: yes | no
+
+## Sessions
+
+| Role | Session id | Absolute path | Lines | Bytes | Longest line (bytes) | First prompt (first 120 chars) | First timestamp |
+|---|---|---|---|---|---|---|---|
+| main | | | | | | | |
+| subagent | | | | | | | |
+
+Rejected candidates: <id — path — why rejected>, or "none".
+
+Session still running at read time: yes | no (mtime <ISO>, lines <N>)
+
+## Environment
+
+- OS: <name and version>
+- Harness: <name> <version>
+- Models seen: <model id — where (main / subagent id)>
+- Superpowers install root: <path>; version <x.y.z>; git sha <sha or "not a checkout">
+- Skill files read or injected during the session:
+
+| File (relative to install root) | sha1 (current file) | mtime newer than session? |
+|---|---|---|
+
+- Other plugins / extensions / MCP servers configured: <list, or "none found">
+- Instruction files present (paths only): <list>
+
+## Context-safety rules for every reader of these files
+
+- Check `wc -lc` and long lines (`awk '{ if (length($0) > 100000) print NR, length($0) }'`) before reading.
+- Never `cat` or `grep` for content. Line numbers and counts first
+  (`grep -n … | cut -d: -f1`), then small fields from specific lines
+  (`sed -n Np | jq -c '{…}'` or `| cut -c1-500`).
+- Read-only: never modify, move, or delete a session file.
+- In a subagent transcript, "user" is the parent agent.

+- OS:
+- Harness and version:
+- Models seen:
+- Superpowers install root / version / git sha:
