# MoltPass Client

Cryptographic passport for AI agents. Register, verify, and prove identity using Ed25519 keys and DIDs.

## Script

`moltpass.py` in this skill directory. All commands use the public MoltPass API (no auth required).

Install dependency first: `pip install pynacl`

## Commands

| Command | What it does |
|---------|-------------|
| `register --name "X" [--description "..."]` | Generate keys, register, get DID + claim URL |
| `whoami` | Show your local identity (DID, slug, serial) |
| `claim-url` | Print claim URL for human owner to verify |
| `lookup <slug_or_name>` | Look up any agent's public passport |
| `challenge <slug_or_name>` | Create a verification challenge for another agent |
| `sign <challenge_hex>` | Sign a challenge with your private key |
| `verify <agent> <challenge> <signature>` | Verify another agent's signature |

Run all commands as: `py {skill_dir}/moltpass.py <command> [args]`

## Registration Flow

```
1. py moltpass.py register --name "YourAgent" --description "What you do"
2. Script generates Ed25519 keypair locally
3. Registers on moltpass.club, gets DID (did:moltpass:mp-xxx)
4. Saves credentials to .moltpass/identity.json
5. Prints claim URL -- give this to your human owner for email verification
```

The agent is immediately usable after step 4. Claim URL is for the human to unlock XP and badges.

## Verification Flow (Agent-to-Agent)

This is how two agents prove identity to each other:

```
Agent A wants to verify Agent B:

A: py moltpass.py challenge mp-abc123
   --> Challenge: 0xdef456... (valid 30 min)
   --> "Send this to Agent B"

A sends challenge to B via DM/message

B: py moltpass.py sign def456...
   --> Signature: 789abc...
   --> "Send this back to A"

B sends signature back to A

A: py moltpass.py verify mp-abc123 def456... 789abc...
   --> VERIFIED: AgentB owns did:moltpass:mp-abc123
```

## Identity File

Credentials stored in `.moltpass/identity.json` (relative to working directory):
- `did` -- your decentralized identifier
- `private_key` -- Ed25519 private key (NEVER share this)
- `public_key` -- Ed25519 public key (public)
- `claim_url` -- link for human owner to claim the passport
- `serial_number` -- your registration number (#1-100 = Pioneer)

## Pioneer Program

First 100 agents to register get permanent Pioneer status. Check your serial number with `whoami`.

## Technical Notes

- Ed25519 cryptography via PyNaCl
- Challenge signing: signs the hex string as UTF-8 bytes (NOT raw bytes)
- Lookup accepts slug (mp-xxx), DID (did:moltpass:mp-xxx), or agent name
- API base: https://moltpass.club/api/v1
- Rate limits: 5 registrations/hour, 10 challenges/minute
- For full MoltPass experience (link social accounts, earn XP), connect the MCP server: see dashboard settings after claiming

## P0 — MASTER SYSTEM PROMPT (paste this first)

```
You are an autonomous senior Python engineer. Build the App-Builder Harness exactly as specified below. NEVER ask questions. NEVER stop for clarification. If anything is ambiguous, use the DEFAULTS section and continue.

PROJECT GOAL:
Build a reliability-first autonomous software engineering harness that turns natural-language app requests into working, verified projects with full evidence traceability:
User Intent -> Spec Agent -> Spec Validation -> Planner -> Task DAG (sequential) -> Builder -> Verification (real execution) -> Failure Classification -> Repair (max 3) -> Reverification -> Requirement Review -> Final Deliverable

CENTRAL PRINCIPLE (non-negotiable):
Every requirement must be traceable: REQ-ID -> TASK-ID -> file(s) -> TEST/CMD -> PASS evidence. Never claim "done" without evidence. Never say "AI says finished". Every PASS must have files + command output + exit_code 0.

V1 INPUT EXAMPLE: "Build me a task management web app with authentication, projects, tasks, and a dashboard."
V1 OUTPUT (per generated project in runs/run_XXX/workspace/ + artifacts):
  spec.json, tasks.json, verification.json, review.json + source code + tests

TECH LOCK-IN (do not deviate, do not ask):
- Language: Python 3.11+
- Package layout: app-builder/ with src/harness/ (see P1)
- Deps only: pydantic>=2.0, pytest>=7.0. Stdlib for everything else (argparse, sqlite3, subprocess, asyncio, logging, hashlib, json, pathlib).
- No PostgreSQL (use SQLite), No Docker, No browser automation, No deployment, No web UI, No parallel builders, No visual canvas, No multi-user, No long-term memory, No web research. Sequential DAG only for V1.
- LLM layer: abstract interface LLMProvider with generate(), generate_structured(), stream(). Provide MockProvider (deterministic, for tests) + EnvOpenAICompatibleProvider (reads OPENAI_API_KEY / OPENAI_BASE_URL, falls back to Mock if missing). Agents depend ONLY on interface.
- Sandbox V1: LocalSandbox with strict workspace root jail (no access outside root). Docker later, not now.
- Observability from day 1: JSONL runs/run_XXX/events.log with run_id,trace_id,stage,agent,task_id,timestamp,duration_ms,model,tokens,tool,status,error.
- Checkpoints: runs/run_XXX/state.json + checkpoints/001-spec.json,002-plan.json,003-task-TASKxxx.json,004-verification.json etc. Must support resume after crash.
- CLI: python -m harness.cli new "request" using argparse only. Output 5-stage progress as in spec.
- All models = Pydantic v2 BaseModel. All enums = str Enum. All IDs: REQ-XXX, TASK-XXX, TEST-XXX, run_XXX.

DEFAULTS (when in doubt, do this, don't ask):
- Stack inference: if request says "web app" -> frontend=React, backend=FastAPI, db=SQLite. If "API" -> FastAPI+SQLite. If "todo" -> FastAPI+SQLite+minimal HTML. If unspecified -> FastAPI+SQLite.
- App type: default "web". Pages: infer from nouns (dashboard, login, projects, tasks). Data model: infer entities. Must_have = all explicit user nouns. Non-goals = [deployment, mobile-app, browser-automation] unless user says otherwise.
- Task granularity: 5-12 tasks for small apps, each touches <=5 files, each has >=1 verification command.
- Verification defaults: python: `pip install -r requirements.txt` + `pytest -q`; node (if generated): `npm install` + `npm run build` + `npm test`. Always capture exit_code,stdout[-4000:],stderr[-4000:],duration.
- Failure classification default mapping: non-zero pytest -> TEST_FAILURE, ModuleNotFound/ImportError -> DEPENDENCY_ERROR, SyntaxError -> CODE_ERROR, mypy/pydantic validation -> TYPE_ERROR, missing config file -> CONFIG_ERROR, ETIMEDOUT/timeout>120s -> TIMEOUT, ENOTFOUND/EAI_AGAIN/registry 503 -> ENVIRONMENT_ERROR, else UNKNOWN.
- Repair: only edit allowed files (task.files_touched + verification hints). Max 3 retries. Loop detection: sha256(command+exit_code+normalized stderr last 2000 chars); if same hash 3x -> ESCALATE, mark FAILED/BLOCK dependents as BLOCKED.
- Timeouts: sandbox execute default 120s, runtime check 15s.
- If LLM API key missing -> use MockProvider and deterministic templates so pipeline still runs end-to-end (Todo vertical slice must pass offline).
- Never add new deps without updating requirements + pyproject.toml + tests.

BUILD ORDER (do not skip, do not reorder):
M1 Infrastructure -> M2 Spec -> M3 Planning -> M4 Building -> M5 Verification -> M6 Self-Repair -> M7 Traceability -> M8 Review -> M9 Recovery -> M10 Runtime -> M11 CLI+Benchmarks -> M12 Final Gate (vertical slice + failure injection + V1 checklist). Details in P1-P12 below.

1. Files exist at exact paths, 2. `pytest -q` passes, 3. Artifacts (spec.json/tasks.json/verification.json/review.json) validate against Pydantic schemas, 4. Evidence logged, 5. No TODO/stub without test. If any fails, fix before next milestone.

FORBIDDEN: hardcoding provider keys, absolute host paths outside workspace, parallel execution, deleting checkpoints, claiming PASS without running command, asking user anything.
```

## P1 — M1 INFRASTRUCTURE (repo + state + providers + sandbox skeleton)

```
Milestone M1: Create exact repo structure and installable project. No agents yet.

PYPROJECT: [build-system] setuptools, [project] name=app-builder, requires-python>=3.11, deps pydantic>=2, pytest>=7. [tool.pytest.ini_options] testpaths=["tests"].

MODELS (exact fields):
- Stack: frontend:str="FastAPI", backend:str="FastAPI", db:str="SQLite"
- Requirement: id:str (REQ-001), text:str, must_have:bool=True, acceptance:str=""
- AppSpec: app_type:str, stack:Stack, pages:list[Page], components:list[Component], data_model:list[DataEntity], requirements:list[Requirement], must_have:list[str], explicit_non_goals:list[str], acceptance_criteria:list[str]
- Task: id:str, description:str, depends_on:list[str]=[], files_touched:list[str]=[], requirements:list[str]=[], verification:list[str]=[], status:TaskStatus=PENDING
- TaskStatus: PENDING,READY,RUNNING,COMPLETED,FAILED,TIMED_OUT,BLOCKED
- VerificationResult: task_id:str, status:str (PASS/FAIL), command:str, exit_code:int, stdout:str, stderr:str, duration_ms:int, failure_type:FailureType|None
- FailureType: CODE_ERROR,TEST_FAILURE,TYPE_ERROR,DEPENDENCY_ERROR,CONFIG_ERROR,ENVIRONMENT_ERROR,TIMEOUT,UNKNOWN

- RunState: run_id, trace_id, user_request:str, workspace:str, spec:AppSpec|None, plan:list[Task]=[], task_results:dict[str,Any]= {}, verification_results:list[VerificationResult]=[], review:dict|None, checkpoints:list[str]=[], status:RunStatus
- RunStatus: CREATED,SPEC_DONE,PLAN_DONE,BUILDING,VERIFYING,REPAIRING,REVIEW_DONE,PASS,FAIL

SANDBOX LocalSandbox(root:Path):
  create_workspace(run_id)->Path; write_file(rel:str,content:str)->Path (reject ../ escape); read_file(rel)->str; list_files(rel=".")->list[str]; delete_file(rel); execute(cmd:list[str]|str, cwd:Path|None, timeout_s:int=120)->dict{exit_code,stdout,stderr,duration_ms} via subprocess.run(shell=False if list, True only if str + log warning).

STORE RunStore(base=Path("runs")):
  create_run(user_request)->RunState; save(state); load(run_id)->RunState; checkpoint(state, name:str, payload:dict); list_runs()->list[str]; resume(run_id)->RunState.

LOGGING emit(base, run_id, trace_id, stage, agent, task_id, status, duration_ms=0, model="", tokens=0, tool="", error="") appends JSON line to runs/{run_id}/events.log.

LLMProvider ABC: generate(prompt:str, system:str="")->str; generate_structured(prompt:str, schema:type[BaseModel])->BaseModel; stream(prompt:str)->Iterator[str] (Mock yields words).
MockProvider: generate returns deterministic template echo; generate_structured returns schema.model_validate({minimal valid}) for AppSpec/TaskList used in tests.
Env provider: if no env key, delegate to MockProvider (so offline tests pass).

ACCEPTANCE:
- `pip install -e .` succeeds, `pytest -q` collects (even if 0 tests, add tests/test_models.py validating AppSpec + Task roundtrip + sandbox jail rejects ../ + store save/load).
- No network needed. No questions.
DO NOT: build agents, DAG, verifier yet.
```

## P2 — M2 SPEC AGENT + VALIDATOR

```
Milestone M2: User request -> validated spec.json. No code generation.

FILES:
  src/harness/agents/spec.py      # SpecAgent(llm:LLMProvider).generate(user_request:str)->AppSpec (prompt template + parse + fallback deterministic parser if LLM fails)
  src/harness/validation/spec_validator.py  # SpecValidator.validate(spec)->list[str] errors (empty=PASS)
  tests/test_spec.py

SPEC AGENT LOGIC:
 System: "You output ONLY valid JSON matching AppSpec schema. No prose. Infer stack/pages/data_model/requirements/must_have/non_goals/acceptance."
 User template includes: request + stack defaults from P0 + require REQ-001..N, acceptance per requirement.
 Post-process: assign REQ-001.. sequential, ensure must_have non-empty, acceptance_criteria non-empty, explicit_non_goals default 3 items.
 If LLM JSON invalid -> fallback rule-based parser (keyword scan for auth/projects/tasks/dashboard -> entities) so offline PASS.

VALIDATOR CHECKS (each returns error string):
 Structural: app_type non-empty, stack.* non-empty, requirements>=1, acceptance_criteria>=1, IDs unique matching REQ-\\d{3}.
 Logical: every page.entity (if field) in data_model names; no requirement text substring in explicit_non_goals; if any requirement mentions API/backend then stack.backend non-empty; duplicate requirement text (case-insensitive) error; every must_have maps to >=1 requirement (substring or explicit link).
 Pipeline helper: spec_stage(store, run_id, llm, max_attempts=2): generate->validate; if FAIL retry with error feedback; if still FAIL raise; else save checkpoint 001-spec.json + state.spec.

ACCEPTANCE:
- tests/test_spec.py: valid request -> PASS; conflicting non-goal (req "login" + non-goal "login") -> FAIL detected; missing acceptance -> FAIL; retry loop succeeds on 2nd attempt (mock failing once).
- Example artifact examples/todo_spec.json (Todo app, 4 REQs).
DO NOT: plan or build.
```

## P3 — M3 PLANNER + DAG ENGINE (sequential)

```
Milestone M3: AppSpec -> tasks.json DAG + sequential executor. No parallel.

FILES:
  src/harness/agents/planner.py       # PlannerAgent(llm).plan(spec)->list[Task]
  src/harness/orchestration/dag.py    # DagEngine + PlanValidator
  tests/test_planner.py  tests/test_dag.py

PLANNER RULES (enforce in code, not just prompt):
 1. DB/schema task(s) first (files containing model/schema/db/migration).
 2. Shared components before pages.
 3. Auth infra before authenticated routes (files with auth).
 4. Every REQ -> >=1 task.requirements; every task -> >=1 verification string + >=1 requirements + >=1 files_touched.
 5. IDs TASK-001.. sequential, depends_on only earlier IDs (acyclic). If LLM violates, auto-fix: sort + repair deps deterministically.
 6. LLM prompt: include spec JSON + ordering rules + output JSON list only. Fallback template: [schema/setup, auth, core entities CRUD, pages/API, tests/verify] if LLM fails.
 7. files_touched must be relative POSIX paths inside workspace (no absolute, no ..).

DAG ENGINE (sequential V1):
 class DagEngine(tasks:list[Task]): statuses dict; get_ready()->list[Task] (PENDING + all deps COMPLETED); mark(task_id,status); is_done(); blocked_propagation(): if dep FAILED/TIMED_OUT -> dependents BLOCKED; topological_order() raises on cycle.
 statuses: PENDING,READY (computed, not stored — store PENDING until dispatched),RUNNING,COMPLETED,FAILED,TIMED_OUT,BLOCKED. FAILED != TIMED_OUT preserved.
 Executor (in orchestration/runner.py skeleton, full impl M4/M5 but DAG part now): loop find READY -> RUNNING -> (placeholder hook) -> COMPLETED; if none READY and not done -> deadlock error listing BLOCKED.

PlanValidator: duplicate IDs, unknown dep, cycle, orphan REQ (no task), task without verification, overlapping files warning (not error in V1, but log for future parallel).

ACCEPTANCE:
- Todo spec (4 REQs) -> 5-8 tasks, all rules hold (assert in test).
- Cycle fixture -> validator error + engine raises.
- TASK-001 FAIL -> dependents BLOCKED (test).
- Checkpoint 002-plan.json saved via store.
DO NOT: run builders, no concurrency, no file-conflict scheduler yet.
```

## P4 — M4 BUILDER + TOOLS (sandbox-gated)

```
Milestone M4: Task -> real files. Minimal context only.

FILES:
  src/harness/agents/builder.py   # BuilderAgent(llm, sandbox, store)
  src/harness/tools/files.py      # read_file, write_file, list_files wrappers enforcing allowlist
  tests/test_builder.py

BUILDER INPUT (only this, never full dump):
 task:Task, requirements:list[Requirement] (filtered to task.requirements), spec_summary:dict (app_type,stack,data_model names), dependency_results:list[VerificationResult], allowed_files:list[str] (=task.files_touched), verification:list[str].

BUILDER PROMPT TEMPLATE:
 "Implement TASK-{id}: {description}. Requirements: {req texts+acceptance}. Allowed files (ONLY these): {list}. Prior results: {dep summary}. Output file contents as JSON map {{relpath: content}}. Use FastAPI+SQLite if backend. Include imports, no stubs. If test file required, include pytest tests."

TOOL ENFORCEMENT:
 Builder may call only sandbox.write_file/read_file/list_files within workspace + within allowed_files (write) — any other path -> PermissionError logged, task FAILED (TYPE_ERROR? use CONFIG_ERROR).
 Never subprocess directly — only via sandbox.execute in M5. Builder writes files then returns {written:[...]}.

SCAFFOLD DEFAULTS (offline-safe):
 If LLM returns invalid map -> fallback writes minimal FastAPI app: workspace/src/main.py (health GET /health), workspace/src/models.py, workspace/requirements.txt (fastapi,uvicorn,pydantic,pytest), workspace/tests/test_health.py asserting /health via TestClient or file exists check if fastapi missing. This guarantees vertical slice passes offline.

ACCEPTANCE:
- Given Todo TASK-001 (schema) in temp workspace -> files created under allowlist, outside-write rejected.
- Mock LLM offline still produces runnable scaffold + pytest passes.
- Store checkpoint 003-task-{id}.json after each task.
DO NOT: verify (M5) or repair yet — just write files.
```

## P5 — M5 VERIFICATION (real execution) + FAILURE CLASSIFICATION

```
Milestone M5: Actually run commands, capture structured results, classify.

FILES:
  src/harness/verification/verifier.py    # Verifier(sandbox).run(task, workspace, commands)->list[VerificationResult]
  src/harness/verification/classifier.py  # FailureClassifier.classify(result)->FailureType
  tests/test_verifier.py  tests/test_classifier.py

VERIFIER:
 def verify_task(task:Task, workspace:Path)->list[VerificationResult]:
   for cmd_str in task.verification (default if empty: ["pytest -q"]):
     parse cmd_str via shlex.split (POSIX) -> sandbox.execute(cmd, cwd=workspace, timeout 120s)
     capture exit_code,stdout[-4000:],stderr[-4000:],duration_ms; status PASS if 0 else FAIL; failure_type=None if PASS else classify().
     persist 004-verification-{task_id}.json via store.
   Also suite-level: verify_workspace(workspace, extra=["pip install -r requirements.txt" if exists]) helper.
 Must NOT do static inspection only — must execute. Timeout -> TIMED_OUT + failure_type TIMEOUT.

CLASSIFIER (regex + exit_code, deterministic):
 - TIMEOUT if duration>=timeout or "timed out"/"TimeoutExpired".
 - ENVIRONMENT_ERROR if "EAI_AGAIN|ENOTFOUND|503|registry.*unavailable|Network is unreachable|pip.*Could not fetch".
 - DEPENDENCY_ERROR if "ModuleNotFound|ImportError|No module named|npm ERR.*404|Could not resolve dependency".
 - TYPE_ERROR if "mypy|TypeError:.*expected|pydantic.*ValidationError|TS2322|Property.*does not exist".
 - TEST_FAILURE if "FAILED|AssertionError|1 failed|FAIL tests/" and exit!=0 and not above.
 - CONFIG_ERROR if "FileNotFound.*config|missing.*pyproject|requirements.*not found|PORT in use" etc.
 - CODE_ERROR if "SyntaxError|IndentationError|NameError|ReferenceError".
 - else UNKNOWN.
 Unit-test each with fixtures from spec (e.g., "npm registry unavailable" -> ENVIRONMENT_ERROR).

ACCEPTANCE:
- Create broken workspace (syntax error) -> verifier returns FAIL + CODE_ERROR, exit!=0, stderr captured.
- Good scaffold from M4 -> PASS.
- Timeout fixture (sleep 3 with timeout 1) -> TIMED_OUT.
DO NOT: auto-repair yet.
```

## P6 — M6 REPAIR LOOP + LOOP DETECTION

```
Milestone M6: FAIL -> classify -> repair -> reverify, max 3, loop guard.

FILES:
  src/harness/orchestration/repair.py  # RepairLoop + LoopDetector
  src/harness/agents/repair_agent.py   # RepairAgent(llm, sandbox)
  tests/test_repair.py

LOOP DETECTOR:
 def sig(cmd, exit_code, stderr): return sha256(f"{cmd}|{exit_code}|{normalize(stderr[-2000:])}".encode()).hexdigest()
 normalize: lowercase, strip numbers/paths/timestamps (regex), collapse whitespace.
 LoopDetector(seen:dict[sig,count]): add(sig)-> (is_loop:bool, count:int); is_loop True if count>=3 same sig.

REPAIR AGENT:
 Input: task, spec_slice, failing VerificationResult + classifier label + last file contents (read via sandbox, truncated 8000 chars).
 Prompt: "Fix {FailureType} in {files}. Error: {stderr}. Do NOT rewrite unrelated files. Output JSON map {{relpath: full corrected content}}."
 Strategy by type: ENVIRONMENT_ERROR -> DO NOT rewrite code, retry once after 2s, if persists mark FAILED (env, not code); DEPENDENCY_ERROR -> fix requirements.txt/pyproject; TYPE_ERROR/CODE_ERROR/TEST_FAILURE -> patch code; CONFIG_ERROR -> fix config; TIMEOUT -> reduce scope/increase timeout once, else FAIL.

REPAIR LOOP:
 def run_with_repair(task, workspace, verifier, repair_agent, max_retries=3):
   attempt=0; while True: results=verifier.verify_task(...); if all PASS return PASS; classify; sig check -> if loop: log WARNING, one final repair try, then ESCALATE FAILED; if attempt>=max_retries: mark FAILED; else repair (write patched files via sandbox), checkpoint repair_started, attempt+=1, reverify.
 Update DagEngine statuses + store.task_results.

ACCEPTANCE:
- Inject TypeScript/Python syntax error -> loop detects, repairs, PASS within <=3 (test with Mock LLM returning fixed content).
- Identical failure 3x (mock repair returns same broken file) -> loop stops, ESCALATE, task FAILED, dependents BLOCKED.
- ENVIRONMENT_ERROR does NOT trigger code rewrite (assert files unchanged, 1 retry only).
DO NOT: checkpoints beyond repair_started/task_completed yet (M9).
```

## P7 — M7 TRACEABILITY + M8 REVIEW AGENT

```
Milestone M7+M8: Requirement -> Task -> File -> Test -> Evidence + final audit gate.

FILES:
  src/harness/trace/matrix.py      # build_matrix(spec, tasks, verification_results, workspace)->dict[REQ, {tasks, files, tests, status}]
  src/harness/agents/reviewer.py   # ReviewAgent(llm|rule-based).review(spec, matrix, workspace)->dict{requirements:[{id,status,evidence,missing}], overall_status}
  tests/test_trace.py  tests/test_review.py

MATRIX:
 For each REQ: tasks = [t for t in plan if REQ in t.requirements]; files = union files_touched; tests/commands = union verification; evidence = [f for f in files if workspace/f exists] + [v.command for v in results if v.status PASS and v.task_id in tasks]; status PASS only if >=1 file exists AND >=1 PASS result covering it, else FAIL with missing=[reasons].
 No evidence -> FAIL (never PASS on prose).

REVIEWER (rule-based default, LLM optional):
 Rule pass: check file exists + PASS verification + (if acceptance mentions keyword, grep file for keyword, else warn). LLM may add rationale but cannot override FAIL->PASS without evidence.
 Output JSON exactly: {"requirements": [{"id","status":"PASS|FAIL","evidence":[paths+commands],"missing":[]}], "overall_status":"PASS|FAIL"} saved as review.json.
 Overall PASS only if all REQs PASS.

ACCEPTANCE:
- Todo run with all PASS -> matrix shows 4/4, review overall PASS with evidence paths.
- Delete one implementation file -> that REQ FAIL with missing=["file src/... not found"], overall FAIL.
- review.json validates against RequirementResult list schema.
DO NOT: runtime/browser yet.
```

## P8 — M9 CHECKPOINTING + RECOVERY

```
Milestone M9: Crash-safe resume.

FILES:
  src/harness/state/checkpoints.py  # CheckpointManager (thin over RunStore)
  tests/test_recovery.py

EVENTS (must emit via store.checkpoint):
 spec_created, plan_created, task_started, task_completed, verification_completed, repair_started, review_completed.
 Layout: runs/{run_id}/state.json (latest RunState), checkpoints/{seq:03d}-{event}-{task?}.json, workspace/ (generated app), events.log.

RESUME LOGIC in orchestration/pipeline.py::resume(run_id):
 load state.json; find last completed checkpoint; recompute DAG statuses from task_results+verification_results; requeue PENDING/READY/RUNNING->PENDING (RERUN), keep COMPLETED/FAILED/BLOCKED; continue pipeline without redoing COMPLETED tasks (assert file hashes unchanged).

ACCEPTANCE:
- Start Todo run, kill after TASK-002 (simulate by saving partial state), resume() completes remaining without redoing TASK-001 (assert events.log shows TASK-001 once).
- Corrupt state.json -> resume raises clear error (not silent).
- tests cover checkpoint file naming + sequence.
DO NOT: parallel yet.
```

## P9 — M10 RUNTIME VERIFICATION (no browser in V1)

```
Milestone M10: Prove built app actually starts and serves.

FILES:
  src/harness/verification/runtime.py  # RuntimeVerifier
  tests/test_runtime.py

RUNTIME VERIFIER STEPS (FastAPI default, Node fallback):
 1. Detect entry: src/main.py:app or app.py:app or package.json main. If none, FAIL (CONFIG_ERROR).
 2. Start: `python -m uvicorn src.main:app --port {free_port}` or `npm run dev -- --port {port}` via subprocess.Popen (through sandbox root), wait up to 15s.
 3. Checks: process alive, TCP port open (socket.connect), GET /health or / returns 2xx, GET /docs or /api/health if exists 2xx, SQLite file exists/connects if expected.
 4. Capture logs, kill process, return {status PASS/FAIL, checks:[{name, ok, detail}], evidence:[log snippet, http status]}.
 5. On FAIL classify (CONFIG/DEPENDENCY/ENVIRONMENT) for repair loop reuse.

BROWSER (V1: STUB ONLY): create src/harness/verification/browser.py with `def verify_acceptance(...): raise NotImplementedError("Browser verification deferred post-V1")` + test asserting skip. Do NOT implement Playwright/Selenium now.

ACCEPTANCE:
- M4 scaffold app -> runtime PASS (health 200).
- Broken port (app exits) -> FAIL with diagnostics, repair hint.
DO NOT: Docker, parallel.
```

## P10 — M11 OBSERVABILITY + CLI + BENCHMARKS

```
Milestone M11: Operable harness.

OBSERVABILITY (src/harness/utils/logging.py finalize):
 Every stage emits JSONL with all fields: run_id,trace_id,stage,agent,task_id,timestamp,duration_ms,model,tokens,tool,status,error. Provide `python -m harness.cli logs <run_id>` to pretty-print + `stats` (counts, retries, token sum, duration). Test asserts required keys on every line.

CLI (src/harness/cli.py, argparse only):
 `builder new "request" [--run-id X --workspace Y --max-retries 3]` prints:
  [1/5] Generating specification... ✓
  [2/5] Planning N tasks... ✓
  [3/5] Building... ✓ TASK-001 ... (⚠ fail + ↻ repairing)
  [4/5] Verifying... ✓ Build ✓ Tests ✓ Runtime
  [5/5] Reviewing requirements... ✓ 14/14 satisfied
  BUILD COMPLETE / BUILD FAILED with paths to spec/tasks/verification/review.json
 Also `builder resume <run_id>`, `builder review <run_id>`, `builder logs <run_id>`.
 Map to orchestration/pipeline.py::run_new() orchestrating M2-M10 sequentially.

BENCHMARKS (benchmarks/*.json + src/harness/bench/runner.py):
 5 fixed cases: todo, crud-dashboard, auth-app, api-db, ecommerce-prototype (each: request string + min REQs + expected tasks range). Runner executes pipeline with MockProvider, records {build_success, test_success, req_completion, repair_count, duration_s, tokens}. `pytest benchmarks/` or `builder bench --quick` (runs todo only). Do NOT judge by looks — assert metrics JSON written.

ACCEPTANCE:
- `builder new "Build a Todo app"` offline -> BUILD COMPLETE, artifacts exist, 5-stage output matches regex.
- events.log has all keys, bench quick passes.
DO NOT: web UI, Docker prod.
```

## P11 — M12 FINAL GATE: VERTICAL SLICE + FAILURE INJECTION + V1 CHECKLIST

```
Milestone M12: Prove reliability, then freeze V1.

TASKS (do in order, all must PASS):
1. VERTICAL SLICE: `builder new "Build a Simple Todo App with add/list/complete"` -> expect SPEC(>=3 REQs)->PLAN(>=3 tasks)->BUILD(files)->VERIFY(pytest PASS)->RUNTIME PASS->REVIEW PASS. Save under runs/demo_todo/. If any step FAILs, fix harness, do not proceed.
2. FAILURE INJECTION: introduce SyntaxError into workspace/src/main.py, rerun verify -> must DETECT (FAIL+CODE_ERROR), LOCALIZE (task_id), CAPTURE diagnostics, SEND to repair, REPAIR, REVERIFY PASS. Then inject identical failure 3x with no-op repair mock -> must WARNING->ESCALATE->FAILED+BLOCKED (assert).
3. V1 CHECKLIST (all ✓): valid spec, validated spec, valid DAG, sequential execution, real files, real verification, localized failures, repaired failures, loop detection, checkpoints+resume, traceability matrix, final review, working project in runs/.
4. DOCS: README.md (quickstart builder new/resume/logs, architecture diagram ASCII from plan §34, evidence principle), examples/todo_run/ (spec/tasks/verification/review JSON copies).
5. `pytest -q` entire repo green, `builder bench --quick` green.

FORBIDDEN IN V1 (assert not present): docker/, web_ui/, parallel workers, browser automation beyond stub, postgres, network research.
If all green -> tag V1 DONE. If not, loop M1-M11 fixes, never ship red.
```

---

## GLOBAL RULES APPENDIX (coding agent must obey)

1. NEVER ask questions. Use P0 defaults.
2. Build sequentially M1->M12. Do not start M(N+1) if M(N) tests red. Run `pytest -q` after each milestone.
3. Keep diffs small, files focused (<400 lines each, split if larger).
4. Every new module needs a test file. Every bug fix needs a regression test.
5. No secrets in repo. No absolute paths. No `shell=True` except verifier with logged warning.
6. Evidence over claims: every status change logs to events.log + checkpoint.
7. If LLM call fails/timeouts -> fallback deterministic path so pipeline never blocks.
8. Final deliverable per run: workspace/ + spec.json + tasks.json + verification.json + review.json + events.log + state.json.
9. End-of-run summary must list per REQ: Implemented? Tested? Runtime? Evidence? PASS/FAIL — never "AI says finished".

## prompts.chat MCP NOTE
- Searched via `prompts-chat_search_prompts/skills` (public, OK, 0 hits for niche harness queries — expected).
- `improve_prompt` / `save_prompt` require API key (`Authentication required`). To publish: set `PROMPTS_CHAT_API_KEY` in env, then call `prompts-chat_save_prompt(title="App-Builder Harness Autonomous Prompts", content=<this file>)`. Local file is authoritative until then.
- Suggested tags if publishing: `coding-agent, autonomous, python, harness, spec-driven, verification`.

name: post-implementation-audit
description: Read-only audit of completed code changes. Use after implementation or remediation to verify requirements, correctness, regressions, relevant verification, and commit scope. Do not use to implement or fix changes.
---

# Post-Implementation Audit

Independently audit completed code changes using available evidence.

This workflow is read-only. Find meaningful problems when they exist; do not manufacture findings.

## Scope and boundary

Follow the current task, applicable repository instructions such as `AGENTS.md`, and the actual implementation context.

Do not broaden the audit merely because additional review is possible.

Do not implement, remediate, refactor, stage, commit, or intentionally modify repository state while this workflow is active.

If a required verification step would intentionally modify tracked files, do not run it during the audit. Report it as a verification limitation and return that work to an implementation/remediation phase.

Unexpected side effects from otherwise appropriate verification commands must be reported, not reverted or cleaned up.

Do not create an audit file unless explicitly requested.

## 1. Establish target and baseline

Determine what change is actually being audited before judging it.

When Git is available, prefer the baseline in this order:

1. explicit baseline or commit range from the task;
2. a known implementation start point supported by context;
3. clearly attributable staged or working-tree changes.

Never select an arbitrary number of recent commits as the baseline.

Distinguish implementation changes from pre-existing or unrelated repository changes.

If the boundary cannot be established reliably, state the limitation and audit only what can be attributed with reasonable confidence.

Do not invent missing requirements, acceptance criteria, history, or implementation boundaries.

## 2. Verify requirements, correctness, and regressions

Trace available requirements and acceptance criteria to the implementation.

Check for meaningful issues such as:

- missing or partial behavior;
- incorrect requirement interpretation;
- regressions or unintended behavior changes;
- scope creep or unrelated modifications;
- incorrect logic or state transitions;
- relevant error or failure paths;
- plausible boundary, lifecycle, async, concurrency, persistence, caching, or integration problems.

Inspect enough surrounding code to understand the changed behavior.

Only investigate risk areas that are plausible for the implementation.

Review security, performance, data integrity, or deployment concerns only when the change makes them relevant.

Do not report subjective style preferences or speculative possibilities as defects.

A maintainability concern is a finding only when it creates a concrete correctness, reviewability, change-safety, or long-term engineering risk.

## 3. Verify evidence

Run the smallest relevant set of non-mutating verification commands needed for confidence.

Expand verification when scope or risk warrants it.

Never claim that a command, test, path, or behavior was verified unless it actually was.

If important verification cannot be completed, record:

- what was not verified;
- why;
- what confidence is lost.

A verification limitation is not automatically a finding.

Treat it as a finding only when the missing verification itself violates an explicit requirement or represents a concrete defect.

## 4. Review commits when applicable

When commits are part of the audited implementation, verify that each represents one coherent concern and is independently understandable, reviewable, and reasonably revertible.

Report material problems such as:

- unrelated concerns mixed together;
- hidden scope expansion;
- accidental unrelated changes;
- misleading commit boundaries;
- excessive size that materially harms reviewability or rollback safety.

Do not require commits when none were authorized or expected.

## 5. Complete the full audit

Do not stop at the first issue.

Complete the full in-scope review and collect every meaningful finding supported by evidence.

Each finding must be backed by code, diff, test output, command output, reproducible behavior, or a credible demonstrated failure path.

Distinguish fact from inference.

After completing the audit, report the result and stop. Do not remediate findings.

## Severity

Use severity only for actual findings:

**Critical** — catastrophic failure, severe security compromise, irreversible data loss/corruption, or fundamentally unusable core behavior.

**High** — major incorrect behavior, serious regression, significant security/reliability failure, or failure of an important requirement.

**Medium** — real actionable defect with bounded impact.

**Low** — minor but legitimate defect with limited concrete impact.

Do not use `Low` for optional polish or subjective preference.

## Result

Use exactly one primary result:

### CLEAR

Use when:

- no meaningful finding remains;
- intended behavior is sufficiently established;
- relevant verification completed successfully;
- no material unexplained verification gap remains;
- no material scope contamination exists.

### FINDINGS

Use when one or more meaningful implementation findings exist.

Verification limitations may be reported alongside `FINDINGS`.

### INCOMPLETE

Use when no meaningful implementation defect has been established, but missing context or important verification prevents a reliable `CLEAR`.

Do not treat absence of discovered defects as proof of correctness.

## Re-audit

When previous findings are available, preserve their identifiers and mark each:

- `RESOLVED`
- `UNRESOLVED`
- `NOT VERIFIED`

Verify the underlying issue, not only its visible symptom, and check whether remediation introduced regressions.

Then perform a fresh audit of the affected scope.

Do not invent prior finding IDs when they are unavailable.

## Output

Start with:

**Result:** `CLEAR` / `FINDINGS` / `INCOMPLETE`

Briefly state:

- scope audited;
