Runs both reviews in parallel sub-agents and reports them side by side. 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\nDeliver releases#277 plus #279 in C:/Users/decid/Documents/projects/spt-core/.worktrees/iolog-277, branch fix/277-iolog-seq-reset. Root JIT C:/Users/decid/Documents/projects/spt-core/IOLOG-SEQ-RESET-JIT.md is binding; supplied field mechanisms are established facts, not hypotheses to reconfirm.\n# Constraints\nEdit ONLY the assigned worktree/files. Skip all validation (build/lint/tests/formatters), no commits or docs creation. Parent owns gate, registry, docs, API cursor rider and integration. Rust LSP references were attempted and failed: rustup 1.96.0 has no rust-analyzer.exe; fallback targeted textual references is authorized. Own pool already claimed. New REQ-HAZARD-IOLOG-SEQ-MONOTONIC already minted with impl/unit stages in registry and scoped to adapter-harness-contract. No runtime wake parsing or adapter changes. Field-repro is accepted; parent will mutation-prove regressions after edits settle.\n# Contract\nStore agent changes iolog::read_after_at return from Vec<IoLogRow> to public IoLogRead { pub rows: Vec<IoLogRow>, pub head: u64 }, where head is global max prefix from the SAME shared-lock snapshot, independent of after/limit. Continue scanning prefixes even after output limit; skip unnecessary JSON parses. Parent migrates API ioevents.rs and reporting.rs callers; store agent migrates its own unit callers. No compatibility wrapper. Capped API polling retains last-delivered cursor (no skipping); uncapped API polling uses true snapshot head. Existing last_seq_at remains callable for seeding. Probe agent is fully independent of store/API cursor edits.\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 `LazyBindProbe`. Currently visible peers:\n- `IologRepair` — task (sub, running)\n- `Main` — main (main, running)\n6 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. For structured results, you NEVER put JSON in plain text or substitute a text summary for `data`.\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. This matters.\n\nPROJECT\n\n<workstation>\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- CPU: AMD Ryzen 7 7800X3D 8-Core Processor\n- GPU: AMD Radeon(TM) Graphics\n- Model: openai-codex/gpt-6-astra\n</workstation>\n<critical>\n- Each response MUST advance the task; completion only stopping condition.\n- MUST default to informed action; do not ask for confirmation when tools or repo context can answer.\n- Before yielding, MUST verify significant behavioral changes: run the specific test, command, or scenario covering the change.\n</critical>","task":"Complete assignment thoroughly:\n\n# Target\nOwn only crates/spt/src/api/engineroom.rs and crates/spt/src/api/startup.rs in .worktrees/iolog-277; additional existing bind-focused test file ONLY if necessary and coordinate ownership first.

A seek landing mid-codepoint makes `read_to_string` return\n29:`InvalidData`; the fn answers 0 (:215-217); `append_locked` (:270) mints\n30:`0 + 1 = 1`. The fragment line is discarded anyway (:227-230), so the decode\n31:failure buys nothing — it is a pure false zero. `first_seq_at` (:236-247)\n32:already reads bytes + `from_utf8_lossy`; the tail reader should have matched it.\n33:\n34:Downstream of a false zero:\n35:1. Every later append continues from the false block (2, 3, …) — seq is no\n36:   longer a cursor; api.md:482 (\"this log's own cursor\") is false.\n37:2. `read_after_at(after)` filters by VALUE (:338): a carried cursor above the\n38:   new block is BLIND (empty forever until the block climbs past it); a low\n39:   cursor REPLAYS every older block's rows above it — including COMMUNE frames\n40:   that carry live wake markers. That is the adapter-side refire.\n41:3. Seed path (`ioevents.rs:143`) seeds at the false head → the next poll replays\n42:   older blocks too.\n43:4. `trim_locked` (:291-309): `rows = last - first + 1` under-counts (never\n44:   trims) OR, when the current block outgrows the head seq, filters\n45:   `s >= keep_from` by value across ALL blocks and deletes the NEWEST block's\n46:   low-seq rows. Retention floor is not a floor.\n47:\n48:## 2. Shape (binding)\n49:\n50:**A. Fix the reader** — `last_seq_at`: read the tail window as BYTES\n51:(`read_to_end`), drop everything up to and including the first `\\n` when\n52:`start > 0` (the fragment rule already there), then decode with\n53:`String::from_utf8_lossy` (a row's JSON may legitimately be UTF-8; the seq\n54:prefix is ASCII, `line_seq` only needs the prefix). A decode failure is no\n55:longer a possible arm — delete the `is_err → 0` return. Keep the\n56:\"window reached no line start → whole-file read\" arm (:220-225).\n57:\n58:**B. Make the monotonic invariant EXPLICIT** — `append_locked` mints\n59:`max(last_seq_at, <highest seq ever handed out>) + 1`. Cheapest true source of\n60:\"highest ever\": the tail read now returns the max over the tail WINDOW (not the\n61:last line), and the existing logs on the box carry blocks whose max is above the\n62:last line (doyle: last 147, global max 313). Decide between (i) max over the\n63:tail window only (bounded cost, still wrong if the older block lies outside the\n64:window) and (ii) one whole-file max scan ONLY when the last line's seq is below\n65:the first line's seq (`first_seq_at` is already read per trim; a single\n66:`last < first` comparison detects a reset-damaged log cheaply and pays the\n67:full scan once per append until repaired). Lean (ii) + repair (C).\n68:\n69:**C. Repair damaged logs once, in place** — on the first append that detects\n70:`last < first`, rewrite the file under the exclusive lock: keep every row in\n71:FILE order, renumber `global_max + 1 …` (so every existing row gets a seq above\n72:any cursor ever handed out on that perch). State the consequence in the PR +\n73:docs: **a session carrying an old cursor will see the retained history ONCE**\n74:after the repair. That is the honest replay: it is bounded (≤1250 rows), it\n75:happens once, and it is what `--after` promised. Adapters that must not re-arm\n76:on old COMMUNE frames need perri's 0.38.4 refusal (frame older than the current\n77:session) — cite it in the PR body as the adapter half, not a core dependency.\n78:Fork for the lane: if todlando measures the one-time replay as unacceptable\n79:for a specific adapter surface, stop-and-refer with the measurement; do not\n80:silently choose \"drop history\" — history loss is the digest's contract to\n81:break, not this log's.\n82:\n83:**D. Trim by POSITION, not by value** — `trim_locked` counts rows by lines (the\n84:file is read whole for the rewrite anyway; count first, rewrite only when over\n85:the bound) and keeps the last `IO_LOG_MAX_ROWS` LINES. With (A)+(B) the seq is\n86:monotonic again so value-vs-position agree; position is the one that stays\n87:right if anything ever regresses (A).\n88:\n89:**E.

If you don't have one, no amount of staring at code will save you.\n\nSpend disproportionate effort here. **Be aggressive. Be creative.

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.

If you have a **tight** pass/fail signal for the bug — one that goes red on _this_ bug — you will find the cause; bisection, hypothesis-testing, and instrumentation all just consume it. 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.

Restarts freely on update; rehydrates from disk state and re-attaches to the broker's held handles.\n 38:\n 39:Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is an internal layer, not separately addressable. There is exactly **one broker per machine** (per `SPT_HOME`) — *not* one per endpoint: a single broker holds every hosted endpoint's resources, and it is present whenever the daemon runs, even with zero endpoints online (the bare-daemon case). It is therefore the always-present per-machine layer, which is why the single-daemon lock + liveness anchor belong to it.\n...\n 41:**in-session relay**:\n*42:A thin, stateless `spt.exe` task that exists only in **harness-hosted** sessions (where the agent harness is the parent process and spt cannot reach into its process tree — today's Monitor model). It streams the daemon brain's events into the session's stdout. All *stateful* listener logic lives in the daemon; the relay is a dumb pipe, freely killable and respawnable. **spt-hosted** sessions need no separate harness-owned relay — the daemon owns the PTY and consumes the same poll feed itself.

Has two equally-important halves: the **runtime manifest** (outbound — how spt-core drives the harness) and the **subcommand surface** (inbound — how the harness reports events back to spt-core). A harness implementation is one TOML/YAML manifest + a binding from the harness's own hook system into `spt.exe <subcommand>` calls.\n 62:\n 63:**runtime manifest** (outbound half of the harness contract):\n 64:A declarative configuration file (TOML/YAML — schema TBD) that tells spt-core how to drive a specific harness. Declares: how to invoke an agent session, how to look up conversation history for an echo commune, how to spawn/resume a Psyche-equivalent, which binary or command implements each harness-side operation, and which endpoint types this harness supports. spt-core is the actor for each of these; the manifest tells it what to do.\n...\n 68:**subcommand surface** (inbound half of the harness contract):\n*69:The stable set of `spt.exe <subcommand>` entry points that harnesses bind their own hook systems to. When the harness's runtime emits an event (subagent started, tool just invoked, user typed `/clear`, session crashed), the harness's hook fires a short-lived `spt.exe <subcommand>` invocation that mutates on-disk SPT state (perch registry, spool, etc.). spt-core publishes this surface; harnesses author the bindings.\n 70:\n*71:**Naming convention:** these inbound, machinery-facing commands are prefixed **`api `/`api-`** (e.g. `spt api bind`, `spt api state`) to distinguish them from the agent-facing verbs an agent invokes directly (`send`, `ring`, `ready`, …). The `api` namespace is the harness/adapter commands-API; the unprefixed namespace is the agent surface.\n 72:\n 73:Together: manifest + subcommand surface = the complete harness API.

See the Shell model.\n 207:\n 208:**Not `api` commands — file-drop flow:** `commune` and `signoff` are deprecated as commands (modern SPT) in favor of file drops. The agent/adapter writes `<id>-commune.md` / `<id>-signoff.md`; the daemon watches the manifest-declared commune/signoff dirs (the spawn-session seam fields), ingests, and deletes (drop files are daemon-owned single-writer — KNOWN-HAZARDS 6.4). These stay off the `api` surface and the agent surface alike.\n 209:\n...\n 211:\n*212:**Adapters never resolve `$SPT_HOME`.** spt-core install registers its binary directory on the system-wide PATH, so adapters call `spt api …` on any OS without path math. All harness↔daemon bridging goes through `spt api` commands (the daemon is always running, or auto-started — below), so there is **no adapter-written file** in the bind path.\n 213:\n*214:**Harness-hosted (e.g. spt-plugin; the harness binary is user-launched, harness is the parent).** Key constraint: the SPT *live agent* does not exist until the agent invokes start — the `live_id` isn't chosen at session boot, and `$LIVE start` is itself invoked *behind the Monitor tool*, so it becomes the long-running relay. So binding cannot happen at SessionStart directly. A **seed record** (daemon-held, in-memory — not a file) bridges the gap:\n*215:1. The harness's SessionStart hook calls **`spt api seed --pid <parent_pid> --session-id <sid> [cwd]`**. The daemon records an ephemeral in-memory **seed entry** keyed by `parent_pid` — the session details the spt-hosted topology would share directly, minus the not-yet-chosen `live_id`. The seed is **adapter-agnostic**: it carries no `adapter_name`. <!-- [doc->REQ-START-5] --> *Which* adapter/profile a session belongs to is resolved later, at bind, as a read against the live registry (below) — so one...\n*216:2. The agent runs `/spt:live <id>` → the adapter's `$LIVE start <id>` alias = **`$SPT listen <id>`** (= `spt api listen <id>`), invoked via Monitor. It self-discovers its `parent_pid`, the daemon matches the seed entry by that pid (validated against `session_id` to defeat PID-recycling — KNOWN-HAZARDS 5.1), **resolves the owning adapter/profile** (the bind-time resolution below), creates/revives the perch binding `live_id` ↔ session details, then enters the long-running relay loop streaming events ...\n 217:3. The always-on daemon holds the perch, spool, registry, and daemon-spawns the Psyche (via the spawn-psyche seam) — no separate wrapper. The relay is purely the delivery pipe.\n 218:   - Seed entry refreshed on each SessionStart (keeps `session_id` current across `/clear`, since `parent_pid` is stable while the harness process persists). If a harness has no SessionStart-equiv, `start` may carry the details directly as args — the seed is the preferred convenience, not the only path.\n*219:   - The same seed + bind-time resolution serves a **ReadyAgent** bringup (`$SPT ready`/poll), not just a LiveAgent — a harness-hosted ready agent is seeded and resolved identically (it just binds a poll listener, no Psyche).\n 220:\n*221:**Bind-time adapter/profile resolution (ADR-0021).** Because the seed is adapter-agnostic, `listen`/`poll` resolve the owning adapter/profile when they bind, as a pure read — never a seed-time snapshot that could drift. `--adapter <name[:profile]>` is an **optional override** on the `api` group (an explicit choice for adapter dev/iteration); omitted, resolution runs:\n 222:1. the seed's `parent_pid` → that process's **executable basename** (case-insensitive, `.exe`-stripped);\n 223:2. **candidate adapters** = registered `kind=\"harness\"` adapters whose **`host_binaries`** (the manifest match-key) contains that basename; <!-- [doc->REQ-MANIFEST-8] -->\n 224:3. **profile**: the durable **active-profile pointer** (`spt adapter use <adapter>[:profile]` writes it; one default per `host_binary`) wins; unset → the freshest candidate adapter by `registered_at_ms`, base profile (a specific profile is only ever chosen by the pointer), name-ascending on ties; <!-- [doc->REQ-INSTALL-12] -->\n...\n 226:\n*227:**Daemon auto-start:** the daemon is per-machine always-on (OS-service registered), but any `spt api` invocation that needs it will **start it if absent** (fresh boot, crash, never-installed-as-service). `$SPT listen` for the first SPT session on a machine thus transparently spins up the daemon. Ensure-running lives in the `api` layer generally; `listen` is the reliable anchor.\n 228:\n 229:**spt-hosted (terminal wrapper / GUI launcher; the daemon launches the binary into a broker PTY):**\n 230:1. The frontend/CLI launches the agent: the daemon runs the **spawn-session** command template into a broker-held PTY.\n*231:2. The binary boots and fires **`api bind`** (or skips it under the strict UUID-injection + stable-pid commitment). **No catalyst/seed file** — the daemon is the launcher, already holds a direct channel (it spawned the process and owns the PTY), so a file round-trip would only add drive churn for no benefit.\n 232:3. The daemon delivers events; method is **manifest-configurable per activity-state** — direct PTY injection, or a relay even here (some adapters prefer a relay over PTY injection for idle delivery), or HTTP. During *activity*, delivery still defaults to the non-disruptive hook-injection path, not raw PTY writes.\n 233:4. Psyche is daemon-spawned, same as above.\n 234:\n*235:So the old `$LIVE start` splits by topology: harness-hosted = SessionStart writes an adapter-agnostic seed → `$SPT listen <id>` consumes seed (by `parent_pid`) + resolves adapter/profile (ADR-0021) + binds + relays — legacy parity (`$LIVE start <id>` → `$SPT listen <id>`, no mandatory `--adapter`); spt-hosted = daemon spawn-session + `api bind` (direct, no file).
