Pins to python3.13 to match the Debian Trixie production target. Documents the dev setup in README and AGENTS.md so a fresh checkout gets a working `python` via `direnv allow` + editable installs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# AGENTS.md
|
|
|
|
Guidance for coding agents working in this repository.
|
|
|
|
## Mission
|
|
|
|
Build `left4me` according to the two implementation plans:
|
|
|
|
- `docs/superpowers/plans/2026-04-22-l4d2-host-lib-v1.md`
|
|
- `docs/superpowers/plans/2026-04-23-l4d2-web-app-v1.md`
|
|
|
|
Do not invent architecture outside these plans unless explicitly requested.
|
|
|
|
## Current Project State
|
|
|
|
- `l4d2host/` and `l4d2web/` implementation directories exist.
|
|
- Implementation plans remain the source of truth for contract changes and task sequencing.
|
|
|
|
## Non-Negotiable Constraints
|
|
|
|
### Workspace and tools
|
|
|
|
- Do not use git worktrees.
|
|
- Local Python venv is direnv-managed via `.envrc` (Python 3.13). After fresh checkout: `direnv allow`, then `pip install -e ./l4d2host -e ./l4d2web pytest`. See README **Local development** for details.
|
|
|
|
### Naming and boundaries
|
|
|
|
- Use `l4d2` naming consistently.
|
|
- Keep host library and web app as separate components.
|
|
- Do not collapse them into one package.
|
|
|
|
### Host library (`l4d2host` / `l4d2ctl`)
|
|
|
|
- Exposed CLI write command set is fixed:
|
|
- `install`
|
|
- `initialize <name> -f <spec.yaml>`
|
|
- `start <name>`
|
|
- `stop <name>`
|
|
- `delete <name>`
|
|
- CLI read commands are allowed for web/host boundary consistency:
|
|
- `status <name> --json`
|
|
- `logs <name> --lines <n> --follow/--no-follow`
|
|
- Runtime paths are rooted at `LEFT4ME_ROOT`, defaulting to `/var/lib/left4me`.
|
|
- Deployment/config management owns global units under `/usr/local/lib/systemd/system` and privileged helpers under `/usr/local/libexec/left4me`.
|
|
- Overlay directories are populated by the web app (workshop downloads, managed-global refresh). The host library only mounts them.
|
|
- Fail-fast subprocess behavior; pass raw stderr; propagate return code.
|
|
- No lock manager, no rollback, no preflight runtime checks.
|
|
- Delete missing instance/runtime dirs must succeed (no-op).
|
|
- Read APIs required for web app integration:
|
|
- `get_instance_status(name)`
|
|
- `stream_instance_logs(name, lines=200, follow=True)`
|
|
|
|
### Web app (`l4d2-web-app`)
|
|
|
|
- Flask + server-rendered templates + vendored HTMX.
|
|
- No external frontend framework/dependencies.
|
|
- Custom CSS with tokenized, consistent link and accent colors.
|
|
- Local username/password auth and `admin` flag.
|
|
- Persist command logs in `job_logs` table (retain indefinitely).
|
|
- Desired vs actual server state model.
|
|
- Live logs in UI for both jobs and servers.
|
|
- Web app host operations go through `l4d2ctl` via a host command client, not direct `l4d2host` imports.
|
|
- Blueprint semantics (locked):
|
|
- private per user in v1
|
|
- live-linked to servers
|
|
- no server-level overrides
|
|
- deleting in-use blueprint is blocked
|
|
- updates apply on next action
|
|
- servers can reassign blueprint anytime
|
|
|
|
## Delivery Workflow
|
|
|
|
1. Read both plan files fully before coding.
|
|
2. Execute plan tasks in order.
|
|
3. Keep changes scoped to one task at a time.
|
|
4. Run task-level tests before moving forward.
|
|
5. Do not claim completion without command evidence.
|
|
6. Keep docs updated when behavior/contracts change.
|
|
|
|
## Verification Expectations
|
|
|
|
Before claiming success on any step, run the relevant command and report actual output status.
|
|
|
|
Typical commands (once components exist):
|
|
|
|
- `pytest l4d2host/tests -q`
|
|
- `pytest l4d2web/tests -q`
|
|
|
|
## Change Control
|
|
|
|
- If a requested change conflicts with this file, follow explicit user instruction.
|
|
- If plans and code diverge, update plans or flag the mismatch clearly.
