feat(opencode): native OpenCode plugin with per-turn injection, write reminders, compaction flush, session-idle gate and pwf tools

New npm package opencode-planning-with-files under
.opencode/packages/opencode-planning-with-files/ (TypeScript, Vitest):

- chat.message appends the framed active plan (plan head, normalized
  progress tail, findings pointer) to every user message, or a
  once-per-turn ambiguity notice when a direct child project carries its
  own live plan
- tool.execute.after appends the progress reminder to write, edit,
  patch, multiedit and apply_patch output
- experimental.session.compacting keeps the plan pointer and attestation
  hash in the compaction context
- event session.idle runs the completion gate in gated mode and
  re-prompts the session with the gate reason through the SDK (Tier 2);
  child sessions are never re-prompted, the shared .stop_blocks and
  .gate_last_ledger counters and PWF_GATE_CAP bound it
- tools pwf_init (root or .planning/<date>-<slug>/, mode autonomous or
  gated with the v3 markers and attestation), pwf_status, pwf_check

The resolver, ambiguity rule, gate decision table, init markers,
attestation check and frame format mirror resolve-plan-dir.sh,
inject-plan.sh, check-complete.sh --gate, init-session.sh and the Hermes
plugin. Each session resolves its plan from its own OpenCode directory.
PWF_PLAN_ROOT fails closed, PLANNING_DISABLED silences every hook.

Also: .opencode/commands/pwf.md and pwf-status.md in OpenCode's command
format, a dogfood entry .opencode/plugins/planning-with-files.ts that
loads the plugin from source when this repository is opened in OpenCode,
.opencode/package.json tracked with the @opencode-ai/plugin dependency,
and a vitest (OpenCode plugin) CI job.

Verified live in OpenCode 1.18.21: plugin loaded, pwf_init/pwf_status/
pwf_check listed, /pwf and /pwf-status listed, a real session message
received the framed plan as a synthetic part.

description: Start planning-with-files (task_plan.md, findings.md, progress.md); flags --gated, --autonomous, --template analytics, then an optional plan name
---
Start the planning-with-files workflow for this project.
Arguments given: "$ARGUMENTS"
1. Call the `pwf_init` tool. Map the arguments: `--gated` sets mode "gated", `--autonomous` sets mode "autonomous", `--template analytics` sets template "analytics"; every remaining word forms the plan name. A name creates an isolated `.planning/YYYY-MM-DD-<slug>/` plan and makes it the active plan; no name uses the project root.
2. Read the created `task_plan.md`, `findings.md` and `progress.md` from the directory the tool reports, then fill in the goal, the next step and the phases for the task at hand before any other work.
3. Follow the planning-with-files skill from then on: update `progress.md` after every action, log errors in the plan, and mark phases complete as they finish.

# opencode-planning-with-files
Native [OpenCode](https://opencode.ai) plugin for [planning-with-files](https://github.com/OthmanAdi/planning-with-files): persistent file-based planning for AI coding agents. The plan lives on disk in `task_plan.md`, `findings.md` and `progress.md`; this plugin keeps it in the model's context on every turn and can hold the session open until the plan reports complete.
## Install
Add the plugin to `opencode.json` (project) or `~/.config/opencode/opencode.json` (global):
```json
{
"$schema": "https://opencode.ai/config.json",
"plugin": ["opencode-planning-with-files"]
}
```
OpenCode installs the package on the next start. Install the skill text as well so the agent knows the workflow:
```bash
npx skills add OthmanAdi/planning-with-files --skill planning-with-files -g
```
That command lands in `~/.agents/skills/planning-with-files/`, one of the paths OpenCode reads natively.
## What the plugin does
| Hook | Behavior |
|---|---|
| `chat.message` | Appends the active plan to every user message: the framed head of `task_plan.md`, the normalized tail of `progress.md`, a pointer to `findings.md`. Resolves `PLAN_ID`, then `.planning/.active_plan`, then the newest `.planning/<slug>/task_plan.md`, then the legacy root file |
| `tool.execute.after` | Appends a progress reminder to the output of `write`, `edit`, `patch` and `multiedit` while a plan exists |
| `experimental.session.compacting` | Keeps the plan pointer and its attestation hash in the compaction summary |
| `event` (`session.idle`) | Completion gate in gated mode: while an `in_progress` phase remains, the plugin re-prompts the session with the gate reason. Block cap `PWF_GATE_CAP` (default 20) and ledger stall detection release the session; child sessions are never re-prompted |
| tools | `pwf_init` (root or `.planning/<date>-<slug>/`, `mode: autonomous` or `gated` with attestation), `pwf_status`, `pwf_check` |
Autonomous and gated plans inject only when `.attestation` (slug) or `.plan-attestation` (root) matches the SHA-256 of `task_plan.md`. `PLANNING_DISABLED=1` silences every hook; `PWF_PLAN_ROOT=<absolute path>` pins the project root and fails closed when it does not resolve. A live plan in a direct child project makes a cwd guess ambiguous and nothing is injected, with a one-line notice.
## Commands
Copy `pwf.md` and `pwf-status.md` from the repository's `.opencode/commands/` into `~/.config/opencode/commands/` (or your project's `.opencode/commands/`) to get `/pwf [--gated] [plan name]` and `/pwf-status`.

/**
* planning-with-files core for the OpenCode plugin.
*
* Pure functions over the filesystem, no OpenCode imports, so the plugin
* entry can stay a thin adapter and this module can be tested directly.
* Behavior mirrors the shell route (resolve-plan-dir.sh, inject-plan.sh,
* check-complete.sh --gate, init-session.sh) and the Hermes plugin:
*
* - plan resolution: PLAN_ID, .planning/.active_plan (BOM tolerant), newest
* .planning/<slug>/task_plan.md, legacy root task_plan.md; slug validation,
* containment, no symlinks; PWF_PLAN_ROOT pin fails closed; a live plan in a
* direct child project makes a cwd guess ambiguous (issue #212)
* - framed injection: bounded payload, content-derived nonce, DATA ONLY preamble
* - attestation: autonomous and gated plans inject only with a matching SHA-256
* - gate: mode token, in_progress phase (per-field max of both status formats),
* block cap PWF_GATE_CAP, ledger stall; shares .stop_blocks/.gate_last_ledger
* - init: root or dated slug directory, .active_plan pointer, v3 markers

* OpenCode plugin entry for planning-with-files.

* Only the plugin function is exported from this module: OpenCode treats every
* exported function of a plugin module as a plugin, so the helpers live in
* ./core.js. Hooks (all fail open: a planning error never breaks a turn):
*
* - chat.message: append the framed active plan to the outgoing user message
* (or a once-per-turn ambiguity notice), plus the queued write reminder
* - tool.execute.after: append the progress reminder to write-like tool output
* - experimental.session.compacting: keep the plan pointer and attestation in
* the compaction summary
* - event session.idle: the completion gate in gated mode, re-prompting the
* session with the gate reason (Tier 2: follow-up inject)
* - tools pwf_init, pwf_status, pwf_check for the model
