## What it does

This skill guides authoring per-seat agent starting points in OpenRig. A starter binds an agent role, initial context, and session origin into a manifest. Value comes strictly from functionality. Pruning context to make a starter smaller damages capability, so starters keep whatever volume the seat needs.

The lifecycle tracks six stages: captured, named, inspectable, used, promoted, and deprecated. The resolver validates entry schemas and blocks secret leakage. It injects the YAML file through `guidance_merge` on startup. Combining `starter_ref` with `session_source.mode: fork` in one RigSpec is currently rejected.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mvschwarz/openrig agent-starters
```

2. **Manually: put the files in place**
- File: `.github/skills/agent-starters/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/mvschwarz/openrig --path skills/_canonical/core/agent-starters
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill agent-starters -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/skills/_canonical/core/agent-starters/SKILL.md

## When to use it
- author declarative starter manifests with defined roles and context
- inspect provenance and block credential leakage in starter artifacts
- refresh an agent seat using `rig expand` and a starter reference
- retire outdated starter configurations through formal deprecation

## Example prompts
- Create a reviewer-v1 starter manifest with pull request evaluation context and assigned roles
- Inspect the provenance and session source of starter reviewer-v1
- Configure rig expand to refresh the reviewer seat with starter_ref reviewer-v1

# Agent Starters

A named, reusable per-seat starting point. Composes an agent role, startup
context, optional native session source, and provenance into something a
user or rig can choose when creating, refreshing, or packaging a seat.

This registry-backed startup context is distinct from the `rig agent-image`
surface and from a VM image. See the current behavior below before treating
optional session provenance as an executable native session source.

## Use this when

- Creating a new seat from a known-good starting context.
- Refreshing a seat with `rig expand` and `starter_ref`.
- Authoring a new starter (registry entry).
- Inspecting an existing starter's provenance, freshness, or recommended status.
- Promoting / deprecating starters in the registry.
- Composing a starter with a Composable Priming Pack (record manifest id/version, runtime, source session id or transcript path, ready-check evidence, freshness state).

## Don't use this when

- You want VM-style deterministic state capture. Starters don't capture VM state.
- You want to copy provider auth material into a starter. **Starters refer to session sources and context; they do NOT copy credentials.**

## What makes a starter valuable

A starter is valuable when it is **functional** — it carries the context the seat needs to do its task well. Functional is the *only* measure of a good starter. Size is not: a smaller starter is not a better one, and a bigger one is not worse. Whatever it took for the seat to become genuinely capable at its job is the right starter — 80K tokens or 800K.

Capture the seat as it naturally is at a functional, proven point. Don't pad it with context the seat doesn't use, and — just as important — don't strip context out to make it smaller. Size is an *outcome* of what the seat needed, never a target.

Never compact, summarize, or shrink a seat in order to make or "lean" a starter. There is nothing valuable in "smaller," and compaction is lossy — you would trade away the exact capability the starter exists to preserve. (Compaction is a separate last-resort step for a seat genuinely near its context limit, with its own before/after plan — never part of capturing a starter.)

## Authoring lifecycle — 6 conceptual states

1. **Captured** — a useful seat/session/context pattern is identified.
