## What it does

This skill turns a validated build sheet into four JSON payloads for the environment, agent, session, and kickoff stages. `payload_generator.py` creates them in sequence. `launch_script_writer.py` then writes `launch.sh`, which chains the IDs and resumes from the last completed step when run again.

Before launch, `payload_validator.py` checks the generated files and scans for exposed API keys. The skill itself makes no network requests; the user runs `launch.sh`. That script reads `$ANTHROPIC_API_KEY` from the shell at runtime and keeps it out of files, payloads, and logs. The launch cannot proceed without the key in the environment.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install agent-launcher-skills@claude-code-skills
```
This installs the whole agent-launcher-skills plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill stage-launch -a claude-code
```

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

### Codex

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills stage-launch
```

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

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path agent-launcher/skills/stage-launch
```

### Windsurf (Devin Desktop)

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

### 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/alirezarezvani/claude-skills/tree/HEAD/agent-launcher/skills/stage-launch/SKILL.md

## When to use it
- turn a build sheet into four API payloads
- write a resumable `launch.sh` launcher
- validate artifacts before launch
- scan payloads for an Anthropic key leak
- create environment, agent, session, and kickoff in sequence

## Example prompts
- Run stage-launch for `./my-agent/build-sheet.json`.
- Generate the payloads in `./my-agent` and write its `launch.sh`.
- Validate `./my-agent` for an API-key leak before launching.

description: Phase 2 of building a Claude Managed Agent — turn a validated build sheet into exact API payloads and a resumable BYOK curl launch script, then launch (environment → agent → session → kickoff) using the founder's OWN Anthropic key. Use when the user says "launch it", "deploy the agent", "create the agent now", or when the orchestrator routes phase=stage-launch. payload_generator.py emits the four ordered payloads; launch_script_writer.py writes launch.sh that reads $ANTHROPIC_API_KEY at runtime and never embeds it; payload_validator.py runs a pre-launch check including an API-key-leak scan. No tool in this skill makes network calls — the user runs launch.sh themselves. Distinct from interview (planning) and grade-iterate (the outcome loop).

# Phase 2 — Stage → Launch

Turn the build sheet into runnable artifacts, then let the founder launch with
their own key. **No script here touches the network or the key** — the user runs
`launch.sh`.

## Workflow

1. **Generate payloads.**
   ```bash
   python3 scripts/payload_generator.py \
     --sheet ./my-agent/build-sheet.json --out-dir ./my-agent
   # -> ./my-agent/payloads/{01-environment,02-agent,03-session,04-kickoff}.json
   ```
   Agent toolset → `always_allow`; every MCP toolset → `always_ask` (baked into
   the agent payload's `permission_policies`).
2. **Write the launch script.**
   ```bash
   python3 scripts/launch_script_writer.py --out-dir ./my-agent
   ```
   `launch.sh` creates environment → agent → session → kickoff **in order**,
   chaining IDs, and **resumes** on re-run (each step skips if its `*.id` file
   exists). It reads `$ANTHROPIC_API_KEY` at runtime.
3. **Validate before launch.**
   ```bash
   python3 scripts/payload_validator.py --dir ./my-agent
   ```
   FAIL blocks — especially a `key_leak` finding. Fix and re-run.
4. **Minimal key step (never in chat).** Check the shell first:
   ```bash
   [ -n "$ANTHROPIC_API_KEY" ] && echo "key present" || echo "export ANTHROPIC_API_KEY=... first"
   ```
   Point the founder to platform.claude.com → API keys. **Never print the key to
   chat, never write it to a file.**
5. **Launch + watch the first poll.**
   ```bash
   export ANTHROPIC_API_KEY=...      # in their shell, not in chat
   ./my-agent/launch.sh
   ```
   Mark checkpoints with Console deep links. Then `goal_state.py set --phase
   grade-iterate` and advance.

## Hard rules (API-key safety)

- **The key never enters chat, a file, a payload, or a log.** `launch.sh` reads it
  from the environment; `payload_validator.py` scans for `sk-ant-…` leaks and FAILs.
- **Sequential launch.** environment → agent → session → kickoff. Watch the first
  poll foreground before declaring success.
- **Resumable.** Re-running `launch.sh` continues from the last created ID.

## Forcing-question library (recommend + cite)

1. "Is the key in your shell env already?" *Recommend:* check `$ANTHROPIC_API_KEY`
   before anything. *Cite:* this SKILL, key-safety rules.
