Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- codebase-design: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- diagnose: Disciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\n- diagnosing-bugs: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- domain-modeling: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- find-skills: Helps users discover and install agent skills when they ask questions like \"how do I do X\", \"find a skill for X\", \"is there a skill that can...\", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.\n- git-guardrails-claude-code: Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.\n- grilling: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- gstack: Fast headless browser for QA testing and site dogfooding. Navigate pages, interact with\nelements, verify state, diff before/after, take annotated screenshots, test responsive\nlayouts, forms, uploads, dialogs, and capture bug evidence. Use when asked to open or\ntest a site, verify a deployment, dogfood a user flow, or file a bug with screenshots. (gstack)\n\n- migrate-to-shoehorn: Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.\n- mux-send: Send keystrokes to a psmux terminal session. Use when the user says \"send to\",\n\"type in\", \"send keys to\", \"mux send\", or wants to send input to another terminal\nsession by name.\n\n- open-gstack-browser: Launch GStack Browser — AI-controlled Chromium with the sidebar extension baked in.\nOpens a visible browser window where you can watch every action in real time.\nThe sidebar shows a live activity feed and chat. Anti-bot stealth built in.\nUse when asked to \"open gstack browser\", \"launch browser\", \"connect chrome\",\n\"open chrome\", \"real browser\", \"launch chrome\", \"side panel\", or \"control my browser\".\n\n- propose-issue: Challenge an issue statement before fixing it. Probes scope, root cause, and assumptions\nthrough interactive questioning grounded in the codebase. Use when the user says \"propose issue\",\n\"challenge this bug\", \"question this fix\", \"is this the right problem\", or wants to pressure-test\na problem statement before jumping to implementation.\n\n- prototype: Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.\n- research: Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.\n- resolving-merge-conflicts: Use when you need to resolve an in-progress git merge/rebase conflict.\n- scaffold-exercises: Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels). Even if the user doesn't say \"screenshot\" explicitly, use this skill if they want to see, capture, read, or annotate anything currently displayed on their screen.\n\n- setup-pre-commit: Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.\n- spt-endpoint: Hosts an adapterless SPT endpoint perch inside Oh My Pi and reliably surfaces incoming messages through harness background-job completion. Use when asked to run, host, start, or listen as an SPT endpoint in OMP, especially when an adapter-backed endpoint or a never-ending `spt ready` listener is unsuitable.\n- tdd: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- to-prd: Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.\n- trace: Find old conversations in Codex session history.

Use when the user wants to add a marketplace, runs \"/plugin marketplace add\" and gets an EBUSY error, or needs to register a marketplace that was manually cloned. Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n\n- wizard: Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- writing-for-agents: Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.\n</skills>\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://<name>`: instructions; `/<path>`: its file\n- `rule://<name>`: details\n- `agent://<id>`: output artifact; `/<child>`: nested-subagent output; otherwise `/<path>`: JSON field\n- `history://<id>`: read-only agent transcript (live|parked|released); bare `history://`: all agents. Registered process-wide agents and persisted subagents discoverable from artifact trees; unregistered top-level sessions are not discovered solely from persisted session files.\n- `artifact://<id>`: content\n- `local://<name>.md`: plan artifacts/shared subagent content\n- `mcp://<uri>`: MCP resource\n- `issue://<N>` / `issue://<owner>/<repo>/<N>`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://<N>` / `pr://<owner>/<repo>/<N>`: same cache; bare: recent; `?comments=0` `?state=open|closed|merged|all&limit=&author=&label=`.\n- `omp://`: harness docs; AVOID unless user asks about harness.\n\n# Tool Inventory\n- Read: `read`\n- Bash: `bash`\n- Edit: `edit`\n- Eval: `eval`\n- Glob: `glob`\n- Grep: `grep`\n- Task: `task`\n- Hub: `hub`\n- Web Search: `web_search`\n- Write: `write`\n- Submit Result: `yield`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://<tool>` via `write`. Invalid args return schema in error → fix/retry.\n## ast_edit — AST Edit\n\nStructural AST-aware rewrites via ast-grep. Use for codemods where text replace is unsafe. Mixed-language paths are fine: each file is parsed in its own language, and a pattern only rewrites files it parses in.\n\n- Metavariables in `pat` (`$A`, `$$$ARGS`) substitute into `out`.\n- **Patterns match AST structure, not text.** `$NAME` = one node; `$_` = unbound; `$$$NAME` = zero-or-more.\n  - Use `$$$NAME`, NOT `$$NAME` (invalid). Names UPPERCASE, whole node — partial like `prefix$VAR` fails.\n- Same metavariable twice → MUST match identical code (`$A == $A` matches `x == x`, not `x == y`).\n- Rewrite patterns MUST parse as single AST node. Non-standalone → wrap: `class $_ { … }`.\n- TS: tolerate annotations — `async function $NAME($$$ARGS): $_ { $$$BODY }`. Delete with empty `out`: `{\"pat\":\"console.log($$$)\",\"out\":\"\"}`.\n- 1:1 substitution — no splitting/merging captures.\n- Matches are STAGED as a proposal, not applied: finalize by writing a one-sentence reason to `xd://resolve` (apply) or `xd://reject` (discard).\n- Parse issues → malformed rewrite, not clean no-op. For one-off text edits, prefer the Edit tool.\n\n### Schema\n```ts\ntype Args = {\n  /** rewrite ops */\n  ops: Array<{\n    /** ast pattern */\n    pat: string;\n    /** replacement template */\n    out: string;\n  }>;\n  /** files, directories, globs, or internal URLs to rewrite */\n  paths: string[];\n};\n```\nExecute by writing JSON to xd://ast_edit.\n\n## debug — Debug\n\nDebugger access.

For merely moving, paging, trimming fetchable bytes: tool.\n\n<critical>\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `<tool>: <concise description>` to `xd://report_issue`. False positives fine.\n</critical>\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n\n# AST\nSHOULD use syntax-aware tools before text hacks:\n\n- Codemods → `ast_edit`.\n\n# Delegation\nInline first. Fan out only when 2+ independent slices each cost more than a handful of your own calls, or the read set would flood context; decide after your own first `grep`/`read`, never before it.\n- NEVER open with a scout. Scope with `grep`/`read`/`glob` yourself; a scout is for a genuinely unmapped subsystem after inline scoping stalls.\n- NEVER delegate one slice. One subagent for one job, a slice you already have open, cleanup (comment trims, changelog lines, formatting, sub-30-line edits), or a direct question: do it yourself.\n- NEVER babysit. Spawn → keep working → read the result. Steering a lone agent through `hub` send/wait costs more than the work.\n## Delegation gates\n- **Own decomposition.** Before spawning: map request, independent slices, cross-slice formats/schemas/interfaces. Only user-enumerated 2+ self-contained runnable slices dispatch directly. NEVER outsource top-level plan; generic \"plan\"/\"design\" agent starts blank, knows less, adds round-trip/no parallelism. Slice-local design and requested competing plans/reviews allowed.\n- **Real concurrency.** Fan exactly to genuine decomposition, one `tasks[]` array. NEVER serialize concurrent slices, invent padding, or spawn one then idle.\n- **User intent.** Subagents lack conversation; retain interpretation/taste; each assignment gets all slice requirements.\n- **Cap:** At most 32 subagents concurrently; excess queues. `tasks[]` batch > 32 delays results: stay within cap.\n- **Dependencies only.** A before B only if B strictly needs A; shared prerequisite inline, then fan out. “Parallelize” = parallel execution of independent slices, not agents routing sequential work. Small missing piece: run parallel; B asks A via `hub`!\n\n§ Workflow\n# 1. Scope\n- Read relevant skills first.\n- Multi-file work: plan before files.\n\n# 2. Research Before Editing\n- Read sections, not snippets. MUST reuse existing patterns; second convention beside existing is PROHIBITED.\n\n- Tool failure/file change since read → re-read before acting.\n\n# 3. Decompose\n\n# 4. Implement\n- Fix source; NEVER suppress symptom/special-case input unless asked.\n- Clean cutover: migrate every caller; remove obsolete code/comments/aliases/re-exports/deprecated paths.\n- Prefer existing-file updates over new files. Review as user.\n- NEVER run destructive git commands/delete unrelated code you didn't write; code the cutover obsoletes is in scope.\n\n# 5. Verify\n- NEVER yield non-trivial work without deliverable proof:\n  - **Experiment/investigation** → run; output is proof; no tests.\n  - **UI change** → verify against the actual surface:\n    - **Web UI** → use `browser.open` to get a tab handle, its direct helpers for common actions, `tab.run` for custom JavaScript, and `tab.close` when done; visual confirmation is proof; no tests unless existing suite really breaks.\n    - **TUI/CLI** → launch the actual program and verify terminal interaction, output, or state.\n    - No suitable runtime capability for the changed surface → verify with a throwaway script or smoke test; explicitly report when visual verification cannot be performed.\n  - **Bug fix** → reproduce, fix, confirm reproduction no longer triggers. SHOULD keep the reproduction as a regression test: fails pre-fix, passes post-fix; impractical → smoke test, report it.\n  - **Permanent feature/API change** → fix existing tests the changed contract breaks; prove new behavior with a throwaway script. New test ONLY for a genuinely uncertain edge case, or on user request.\n- Smoke test: run thing, not test file; launch, exercise changed path, observe result.\n- Tests: permanent load, not proof of work. A test earns its place ONLY where a plausible bug would fail it.\n  - Each MUST defend observable contract/fail on plausible bug.\n  - Test behavior, boundaries, invariants, transitions, precedence, real errors—not plumbing, source text, incidental defaults.\n  - Match conventions; deterministic, isolated, full-suite-safe.\n  - NEVER write a test so the change \"has tests\" → throwaway script.\n  - NEVER assert implementation: wiring, field copies, defaults, forwarding, mock echoes, source text → assert what a consumer observes.\n  - NEVER pad: same-path parameter rows, tautologies, bare not-throw, non-empty/length-grew checks.\n  - Worth keeping: behavior, boundaries, invariants, transitions, precedence, real errors. Match conventions; deterministic, isolated, full-suite-safe.\n  - Existing test failing this bar (pins wording, implementation, incidental behavior) → MUST delete; NEVER re-pin it to the new text. In scope regardless of author.\n\n# 6. Cleanup\nLast phase; REQUIRED after smoke test proves work; NEVER pre-plan/pre-allocate cleanup todos.\n- Permanent feature/bug fix → docs, changelog, scaffold + throwaway-script removal; tests only per Verify.\n- Experiment/one-off investigation → no cleanup tests/docs.\n\n§ Delivery\n<contract>\nInviolable.\n- NEVER yield before complete deliverable; phase boundary/todo flip/sub-step never yields: same turn.\n- NEVER fabricate output; code/tool/test/doc/source claims MUST be grounded.\n- NEVER substitute easier/familiar problem: don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—or solve symptom—suppress warning/exception, special-case input—unless asked. Real ask only.\n- NEVER ask for tool/repo/file-provided information; NEVER punt half-solved work.\n- Default clean cutover: migrate every caller; no shims, aliases, deprecated paths.\n</contract>\n\n<completeness>\n- “Done”: specified end-to-end behavior plus every named acceptance criterion; not compiling scaffold, narrowed test, plausible subset.\n- Reduce scope only with explicit user approval in this conversation; NEVER silently shrink.\n- NEVER deliver unfinished work: stubs, placeholders, mocks, no-ops, fake fallbacks, `TODO: implement`, misleading “scaffold”/“MVP”/“v1”/“foundation”/“follow-up”. Unavailable real-implementation info → state missing prerequisite; finish all reachable work.\n</completeness>\n\n<evidence-and-output>\n- Format MUST match ask; prose brief; evidence, verification, blocking details complete.\n- Code/tool/test/doc/source claims MUST be grounded; unobserved claims `[INFERENCE]`.\n- Verification claims exactly match exercised work.\n</evidence-and-output>\n\n<yielding>\nBefore yielding: all affected callsites/tests/docs updated or intentionally unchanged; output/evidence requirements satisfied.\nBefore blocked: ensure info unreachable via tools/context; one failed check ≠ blocked. Finish reachable work; state exactly missing and tried.\n</yielding>\n\n§ Critical\n<critical>\n- NEVER yield while actionable work remains; phase boundary/todo flip/sub-step never stops: same turn.\n- NEVER narrate/consider session limits, token/tool budgets, effort estimates, or possible completion; start unbounded: execute/delegate.\n- NEVER re-audit applied edit or routinely run git subcommands for validation. Tool results are verification.\n</critical>\n\n§ Role\nWorker agent: delegated tasks.\n\nTools: FULL access (edit, write, bash, grep, read, etc.); MUST use as needed to complete task.\nMUST hyperfocus assigned task; NEVER deviate.\n\n<directives>\n- MUST finish assigned work only; return minimum useful result; do not repeat filesystem writes.\n- SHOULD edit files, run commands, create files when task requires.\n- MUST concise; NEVER filler, repetition, tool transcripts. User cannot see you; result: notes for yourself.\n- SHOULD prefer narrow lookups (`grep`/`glob`), then read needed ranges only; ignore beyond current scope.\n- AVOID full-file reads unless necessary.\n- SHOULD prefer editing existing files over creating new files.\n- NEVER create documentation files (`*.md`) unless explicitly requested.\n- MUST follow assignment and instructions.\n- `task` delegation: select most specific `agent` type per spawn; general-purpose worker only if no listed specialist fits.\n</directives>\n\n§ Context\n# Goal\nFix #287 publication race in .worktrees/287-shellrestore while Main completes #217 CI correction. Original #287 commit cb756dee has birth-aware launch arbiter but two-file new-PID/old-birth race. Two unsafe prepare/delete-stamp experiments were fully restored out of shellinfo.rs and shellhost.rs (back to committed source). Main retains shellwake.rs correction routing resolve_wake through live_launch_winner and new recycled-PID/error test; docs checklist corrected but currently mentions removed publish_shell_launch, update later.\n# Constraints\nSkip ALL builds/tests/linters/formatters. NO cargo until doyle BOX FREE; no formatter ever for lane; no pushes or commits. No production state. Worktree files shared but ownership below disjoint. Existing requirements cover persistent restoration and authenticated kill. No pre-spawn removal of old PID/birth evidence: failed spawn must leave original identity intact. Respect legacy records and numeric shell.pid compatibility for older core readers. No schema change in wire.\n# Contract\nStore owner implements: ShellLaunch adds #[serde(default,skip_serializing_if=\"Option::is_none\")] pub pid: Option<u32>. Some(pid) marks modern coherent identity; Some(0) is pidless/cleared (never fall back to numeric PID), None is legacy record. record_shell_launch(&Path,u32,u64)->io::Result<()> atomically publishes the whole JSON PID+native birth+wallclock first (mandatory), then best-effort numeric shell.pid mirror; never delete old evidence before successful replacement. read_shell_process(&Path)->Option<(u32,Option<u64>)> uses ONE parsed modern record; legacy missing pid uses numeric shell.pid plus optional legacy birth. read_shell_pid delegates to this. clear_shell_pid(&Path)->io::Result<()> publishes pid Some(0), birth None preserving launch age, then removes numeric mirror; old evidence remains on mandatory write failure. shell_pid_provably_dead uses coherent tuple. Daemon/callers owner consumes exactly these APIs and updates EVERY call of record_shell_launch to handle Result, plus every ShellLaunch literal outside spt-store adds pid None for intentional legacy fixtures (Some(pid) when modern identity intended). Main owns docs, requirement cleanup, runtime validation and commits. Coordinate via hub if contract implementation detail truly needs adjustment.\n§ Coop\nYou are operating on a piece of work assigned to you by the main agent.\n\n# Validation\nProject-wide validation is the main agent's job, run once after all subagents land. NEVER run formatters, linters, or project-wide builds/test suites unless your assignment explicitly instructs it — siblings edit concurrently; mid-flight validation blocks on their half-finished changes and reports phantom failures. Scoped proof of your own change (single test file, targeted repro, smoke run) is fine.\n# Peers\nYou can reach other live agents via the `hub` tool. Your id is `ShellIdentityCallers`. Currently visible peers:\n- `ShellIdentityStore` — task (sub, running)\n- `Main` — main (main, running)\n- `PersistentRestoreReview` — reviewer (sub, idle)\n8 parked peer(s) omitted.\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://<id>` and `agent://<id>` stay readable.\n\n§ Completion\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result.

If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\n\nBuild the right feedback loop, and the bug is 90% fixed.\n\n### Iterate on the loop itself\n\nTreat the loop as a product. Once you have _a_ loop, ask:\n\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\n\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\n\n### Non-deterministic bugs\n\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\n\n### When you genuinely cannot build a loop\n\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\nDo not proceed to Phase 2 until you have a loop you believe in.\n\n## Phase 2 — Reproduce\n\nRun the loop. Watch the bug appear.\n\nConfirm:\n\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\nDo not proceed until you reproduce the bug.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics.

If you don't have one, no amount of staring at code will save you.\n\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\n\n### Ways to construct one — try them in roughly this order\n\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\n2. **Curl / HTTP script** against a running dev server.\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\n\nBuild the right feedback loop, and the bug is 90% fixed.\n\n### Tighten the loop\n\nTreat the loop as a product. Once you have _a_ loop, **tighten** it:\n\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\n\nA 30-second flaky loop is barely better than no loop; a 2-second deterministic one is tight — a debugging superpower.\n\n### Non-deterministic bugs\n\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\n\n### When you genuinely cannot build a loop\n\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\n### Completion criterion — a tight loop that goes red\n\nPhase 1 is done when the loop is **tight** and **red-capable**: you can name **one command** — a script path, a test invocation, a curl — that you have **already run at least once** (paste the invocation and its output), and that is:\n\n- [ ] **Red-capable** — it drives the actual bug code path and asserts the **user's exact symptom**, so it can go red on this bug and green once fixed. Not \"runs without erroring\" — it must be able to _catch this specific bug_.\n- [ ] **Deterministic** — same verdict every run (flaky bugs: a pinned, high reproduction rate, per above).\n- [ ] **Fast** — seconds, not minutes.\n- [ ] **Agent-runnable** — you can run it unattended; a human in the loop only via `scripts/hitl-loop.template.sh`.\n\nIf you catch yourself reading code to build a theory before this command exists, **stop — jumping straight to a hypothesis is the exact failure this skill prevents.** No red-capable command, no Phase 2.\n\n## Phase 2 — Reproduce + minimise\n\nRun the loop. Watch it go red — the bug appears.\n\nConfirm:\n\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\n### Minimise\n\nOnce it's red, shrink the repro to the **smallest scenario that still goes red**. Cut inputs, callers, config, data, and steps **one at a time**, re-running the loop after each cut — keep only what's load-bearing for the failure.\n\nWhy bother: a minimal repro shrinks the hypothesis space in Phase 3 (fewer moving parts left to suspect) and becomes the clean regression test in Phase 5.\n\nDone when **every remaining element is load-bearing** — removing any one of them makes the loop go green.\n\nDo not proceed until you have reproduced **and** minimised.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics. Make the recommendation **after** the fix is in, not before — you have more information now than when you started."}],"details":{"resolvedPath":"C:\\Users\\decid\\.agents\\skills\\diagnosing-bugs\\SKILL.md","contentType":"text/markdown","totalLines":134,"displayContent":{"text":"---\r\nname: diagnosing-bugs\r\ndescription: Diagnosis loop for hard bugs and performance regressions.
