# mission-slice-sop

Guides agents through a mission or slice, from resolving its context to checking the result and handing work off. Useful for projects that track delivery in OpenRig files.

## What it does

The skill sets out a working loop for missions and slices: resolve the selected project path, build and run the product, record what was verified, then pass the work on. A slice uses `SPEC.md`, `PROGRESS.md`, `PROOF.md`, and the `proof/` directory. A mission uses `SPEC.md` and `NOTES.md`.

Planning defines the goal and what counts as done. The builder runs the result, while QA compares the delivery with the plan and records a verdict. One agent can cover all three roles on a small slice. The records should support delivery, not hold it up: `rig scope audit` is advisory and does not block a build.

Before starting, the skill calls for `rig whoami --json` and a lookup from `project.yaml` through the selected context. For a real transfer, use `rig queue handoff`; it closes the source task and assigns a successor. `rig queue create` leaves an informational message instead, so it does not transfer ownership.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill mission-slice-sop -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/mission-slice-sop/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/mission-slice-sop/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill mission-slice-sop -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/mission-slice-sop/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill mission-slice-sop -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/mission-slice-sop/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mvschwarz/openrig mission-slice-sop
```

2. **Manually: put the files in place**
- File: `.github/skills/mission-slice-sop/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill mission-slice-sop -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mvschwarz/openrig --path packages/daemon/assets/plugins/openrig-core/skills/mission-slice-sop
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/mission-slice-sop/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill mission-slice-sop -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mvschwarz/openrig/tree/HEAD/packages/daemon/assets/plugins/openrig-core/skills/mission-slice-sop/SKILL.md

## When to use it
- record a slice's goal and completion criteria
- save verification evidence in `PROOF.md` and `proof/`
- restore agent context after compaction
- assign the next agent with a queue handoff
- compare a delivery with its plan and record the QA verdict

## Example prompts
- Work through the selected OpenRig slice using its specification.
- Check the slice result, add evidence to `PROOF.md`, and update `PROGRESS.md`.
- Hand this task to the next agent with `rig queue handoff`.

# Mission/Slice SOP — Part A

Use this skill to actually **do** mission/slice work: track on the canonical files, record what you proved, hand off through them, and survive compaction on them. **Do the work described here; do not merely explain the protocol.**

**Full convention SSOT:** repo `docs/reference/sdlc-conventions.md`; installed `$OPENRIG_HOME/reference/sdlc-conventions.md`. This skill is the concise Part-A teaching surface and does not replace the full convention.

## Resolve the work first

Run `rig whoami --json`, then resolve `project.yaml -> mission.yaml -> active
slice.yaml -> selected component or wave map -> addressed context`. The complete
lookup and precedence rule is `docs/reference/product-journey-sdlc.md#resolve-the-selected-path`
(installed: `$OPENRIG_HOME/reference/product-journey-sdlc.md#resolve-the-selected-path`).
Read the selected addresses and source needed for this task; skills available in
your profile are capabilities, not a mandatory reading list. No composition means
light Part A. Role names and idle seats add no gates. Explicit rigor and authored
wave boundaries retain their named checks.

The light inner loop is ground yourself → build → test with your own eyes →
iterate → record and return the whole outcome. The builder may hold this check
on a tiny change. Independent review runs only when selected, and once at an
authored wave boundary rather than once per slice.

Part B is defined in the conventions SSOT and runs only when explicitly assigned
to named work. If you believe it is needed, state the reason to the owner and
continue on the selected path until that choice changes.

## Proportionality — this SOP serves shipping; it is not the work itself

The working product is the deliverable. This bookkeeping exists so the work survives handoff, compaction, and review — nothing more. **Match it to stakes.** The `rig scope audit` backstop is **advisory and fail-open**: it never blocks a build and is not a gate you clear before proceeding. If you're spending more time on the convention files or the audit than on the running product, stop and go build. Running the full apparatus on a small change is the letter-worship failure, not diligence.
