# Implementation: Status Script
## Changes Made
### 1. Core script: `scripts/status.py` (980 lines)
Full implementation of all commands specified in the SPEC:
- `--task {name}` — Shows phase, allowed/forbidden actions, next artifact, next phase, approval status
- `--list` — Lists all tasks with phase and next step
- `--create-task {name}` — Creates task folder with `.state`=new, validates kebab-case, refuses duplicates
- `--transition {phase}` — Validates and writes `.state` transitions, refuses illegal transitions, refuses past `:awaiting_approval` without `--approve`, validates required artifacts and forbidden artifacts
- `--approve` — Transitions `:awaiting_approval` → `:approved`, records in `.state.approvals`, refuses if not in awaiting_approval sub-state
- `--validate-folder` — Checks for out-of-order artifacts, flags manually created tasks
- `--audit` — Four categories: out-of-order artifacts, state-artifact inconsistency, unauthorized git modifications, manually created tasks
- `--claim / --release` — Multi-agent task claiming with `.state.lock` files, timeout, overclaiming
- `--next-available / --available` — Work discovery for multi-agent, filters by agent role
- `--can-edit` — Returns ALLOWED/DENIED based on current phase
- `--scope-check` — Returns IN_SCOPE/OUT_OF_SCOPE for file paths
- `--same-session` — Heuristic session check
### 2. Approval sub-states
- Phases with approval: research, decomposition, design, test_design
- Sub-states: `{phase}:awaiting_approval` and `{phase}:approved`
- `--transition` refuses past `:awaiting_approval` without `--approve`
- `--approve` records timestamp and approver in `.state.approvals`
### 3. Forbidden artifacts per phase
- Full mapping from SPEC implemented in FORBIDDEN_ARTIFACTS dict
- `--validate-folder` checks and reports violations
- `--transition` refuses if forbidden artifacts exist
### 4. Multi-agent support
- Agent Configuration parsed from `.agent.md`
- `.state.lock` files with agent ID, phase, claimed timestamp, expiry
- Configurable lock timeout (default 30 min)
- `--claim` validates agent is configured for the phase
- `--next-available` returns highest-priority unclaimed task matching agent phases
### 5. Tests: `tests/test_status.py` (25 tests)
- Create task (valid, invalid names, duplicates)
- State transitions (legal, illegal, approval gates)
- Approval gates (approve, refuse wrong phase, record log)
- Folder validation (valid, no state file, out-of-order artifacts)
- Artifact validation (missing required, forbidden)
- Show task (phase display, allowed/forbidden)
- List tasks
- Tool hooks (can-edit, scope-check)
- Audit (manual tasks, clean tasks)
## Files Created
- `scripts/status.py` (980 lines)
- `tests/test_status.py` (25 test cases)
## Test Results
- 183 tests passing (including all 25 new status.py tests)
- Python compilation clean
