CI / build (push) Has been cancelled
v2.0: state enforcement, project scoping, harness integration
State Enforcement (v2.0):
- .state file as single source of truth for task phase
- Approval gates for research, decomposition, design, test_design
- status.py --transition refuses illegal phase transitions
- status.py --validate-folder detects out-of-order artifacts
- status.py --audit checks all tasks for violations
- status.py --create-task is the only valid way to create tasks
- Pre-v2.0 tasks without .state are UNTRACKED -- all commands refuse them
- New --upgrade command bootstraps .state files for existing tasks

Project Scoping:
- --project flag added to all status.py commands across 16+ files
- _find_project_dir errors instead of silently falling back to ~/.automaton/
- --scope-check marks framework files OUT_OF_SCOPE when working on a project
- Dashboard handlers use stored project_root instead of re-detecting from CWD
- Prompts reference ~/.automaton/scripts/vram_detect.py (not {project}/.automaton/)

Harness Integration:
- status.py --can-edit now supports project-level checks (no --task required)
- --can-edit --file checks file scope without --task
- --json output for machine-readable harness integration
- opencode plugin (plugins/automaton-guard/plugin.ts) intercepts edit/write
- Git pre-commit hook (scripts/git-hooks/pre-commit) blocks commits without task
- Formal integration contract (contracts/harness-integration.md)

Other:
- upgrade.sh delegates to status.py --upgrade instead of manual heuristics
- Phase prompts reference --project {project} for multi-project scoping
- 200 tests passing (14 new)

# AGENTS.md — Automaton Framework
This file contains the information coding agents need to work effectively on the automaton framework itself.
## Project Overview
Automaton is a **contract-based, state-enforced workflow framework** for LLM agents. The framework enforces disciplined engineering workflows computationally via `.state` files, `status.py` phase gates, and approval gates — not just via prompts.
## Repository Layout

## Build & Test Commands
```bash
# Compile all Python files
python -m py_compile automaton/**/*.py automaton/dashboard/**/*.py
# Run the test suite
python -m pytest tests/ -v
# Run a single test file
python -m pytest tests/test_task.py -v
# Syntax-check shell scripts
bash -n scripts/*.sh
# Start the dashboard
python -m automaton.dashboard
```
## Conventions
- **Prompts** live in `prompts/` and use `{placeholder}` syntax.
- **Task paths** must always be written as `{project}/.automaton/tasks/{task-name}/`.
- **Scripts** should be written in Python if they need complex parsing or testing; Bash is OK for simple glue.
- **Tests** are required for any new Python code or significant script logic.
- **No orchestrator runtime** — keep the framework prompt-driven. Do not add an agent harness.
- **No Rust rewrite** — Python/Bash are the implementation languages.
- **State enforcement** — all phase transitions must go through `status.py --transition`. All task creation must go through `status.py --create-task`. All approvals must go through `status.py --approve`.
## State Enforcement (v2.0)
The framework enforces the state machine computationally:
- **`.state` file**: Each task has a `.state` file that is the single source of truth for its current phase
- **`status.py --transition`**: All phase transitions must go through this command; illegal transitions are refused
- **Approval gates**: Research, Decomposition, Design, and Test Design phases require explicit user approval before proceeding (`:awaiting_approval` → `:approved`)
- **`status.py --validate-folder`**: Detects out-of-order artifacts (phase skipping)
- **`status.py --audit`**: Comprehensive audit across all tasks for violations
- **`status.py --create-task`**: The only valid way to create task folders
- **`status.py --upgrade`**: Bootstraps `.state` files for pre-v2.0 tasks that lack them
- **FORBIDDEN actions in prompts**: Each phase prompt explicitly lists what agents cannot do
- **Untracked tasks**: Tasks without `.state` files are UNTRACKED. All commands (`--transition`, `--can-edit`, `--task`) refuse to operate on them. Run `--upgrade` to bootstrap `.state` files.
## Harness Integration
`status.py --can-edit` provides a pre-edit gate that any agent harness can call before allowing file modifications. This is the primary enforcement layer. See `contracts/harness-integration.md` for the full integration contract.
The framework provides three enforcement layers:
1. **Harness pre-edit hook** (`--can-edit`) — blocks edits before they happen. Supported by opencode via the `automaton-guard` plugin at `plugins/automaton-guard/`.
2. **Git pre-commit hook** (`scripts/git-hooks/pre-commit`) — blocks commits when no task is in an edit-allowed phase. Works for ALL harnesses.
3. **Prompt-based rules** (ALLOWED/FORBIDDEN sections) — advisory only, relies on agent discipline.
Modes:
- `--can-edit --project {p}` — Is editing allowed on this project? (checks for tasks in implement/doc_review)
- `--can-edit --project {p} --file {path}` — Same, plus file scope check
- `--can-edit --project {p} --task {t}` — Is this specific task in an edit-allowed phase?
- `--can-edit --project {p} --task {t} --file {path}` — Same, plus file scope check
- Add `--json` for machine-readable output
## Adding or Updating Prompts
1. Edit the relevant file in `prompts/`.
2. Run `python -m pytest tests/test_prompt_paths.py` to ensure task paths are canonical.
3. Update `CHANGELOG.md` under `[unreleased]`.
## Adding a New Script
1. Place the script in `scripts/`.
2. Make it executable if it is entry-point code (`chmod +x`).
3. Add tests in `tests/` if the script is Python.
4. Update `README.md` and any prompts that reference it.
## Dashboard Development
- The dashboard is a **web application** served by a Python HTTP server.
- Static assets are in `automaton/dashboard/html/`.
- Core logic is in `automaton/dashboard/core/`.
- The dashboard is scope-aware: framework mode when run from `~/.automaton/`, project mode otherwise.
## CI
Gitea CI runs on every push:
- `python -m py_compile`
- `python -m pytest tests/`
- `bash -n scripts/*.sh`
See `.gitea/workflows/ci.yml`.
