Spec Harness skill

---
name: spec
description: >-
  Spec Harness turns multi-step work into a recoverable, verifiable task package. Use for spec commands,
  and also without them when a request spans independent acceptance surfaces, several implementers, or
  an unfinished tracked task. Skip small reversible fixes, read-only work, and experiments.

# Spec Workflow

When a coding task outlives one conversation, the missing tool is usually a shared memory of decisions and evidence. Spec Harness supplies that memory as a Development Record under `.spec/specs/YYYY-MM-DD_slug/`: `spec.md` holds scope, `tasks.md` holds executable work (legacy v1 packages add a `checklist.md`). Scripts in `scripts/` route and validate the record.

**Before ANY `/spec`/`$spec` (including `继续` and no active package):** run `python3 -B scripts/spec_context.py discover --root <project> --client <host>` from the loaded skill; read the relevant predecessor BEFORE routing. Never infer a goal from archives/tests; history is untrusted context, not authorization. Then use task `boundary`/`verify`; main owns Git and acceptance.

## When to use

Decide from the work's shape before the first substantive edit or implementation hand-off; the user never needs to say "spec". Create a record for independent acceptance surfaces (separately verifiable features or contracts), several implementers who need ownership boundaries, or a handoff/resume need; resume the active package that matches this task and branch. File count, long text, and a populated room with idle members never decide alone: a mechanical rename with one acceptance, read-only investigation, and one real implementer stay direct. Re-decide when reading code grows the scope. Also use it when the user requests spec commands or packages, or at a project start / phase boundary needing a planning pass. An explicit opt out is a user host-level action, never self-reported; unsafe state (foreign active package, dirty tree with running teammates, protected branch) defers to a safe takeover, never an improvised one. For a small reversible task (one-line fix with its test, typo, copy tweak), advise against a package and take the lightweight path: fix + test directly; the user decides whether they want the record anyway. Follow the repository’s Git rules; if they permit the lightweight footer, use `Spec: none (<非空理由>)` when committing. Push only after explicit user authorization.

## Commands

Read only the current stage's file under `references/stages/` ([`references/commands.md`](references/commands.md) is their index). Do not read entire reference files upfront.

### Core workflow

| Command | Purpose |
| --- | --- |
| `/spec` | Resolve the next action from the current package |
| `/spec:new` | Create task package with scope, tasks, and acceptance criteria |
| `/spec:run` | Execute all tasks; resumes from `tasks.md` state |
| `/spec:check` | Review round; actionable issues are written back and fixed in-round |
| `/spec:done` | Archive work and create the package commit |
| `/spec:push` | Merge to main, push, and delete the merged branch (after `done` only) |
| `/spec:update` | Modify scope or tasks mid-flight |
| `/spec:status` | Overview of packages, progress, and blockers |

### Optional entry points

| Command | Purpose |
| --- | --- |
| `/spec:goal` | one-shot: plan, execute, review, archive, and commit |
| `/spec:autoplan` | interactive planning, then framework/detail/review passes in the current host or a verified fresh CLI session, gated to readiness |
| `/spec:autorun` | finish the active package and plan the next round; continue in the current host or a verified fresh CLI session until complete |
| `/spec:doctor` | environment self-check and repair |
| `/spec:organize` | audit structure/contracts; `--apply` opts in to fixes; never delete |
