Prompt to paste

I want to install this Agent Skill for this project in Codex.

Source SKILL.md: https://github.com/majiayu000/claude-skill-registry/blob/HEAD/skills/data/mission-ralph/SKILL.md

First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/mission-ralph/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

Copying this prompt does not install or run the skill. Review third-party files before use. Codex skill guide

/mission-ralph - Automatic Background Execution

Launch the Ralph loop in background. Runs automatically until all tasks complete or a critical blocker halts execution.

The Process

Validate feature - Check feature exists and has tasks
Activate feature - Run bd update FEATURE_ID --status in_progress
Ask launch mode - "Start Ralph in mprocs (visible) or background (invisible)?"
Launch Ralph:
- If background: Run the script directly
- If visible: Print the command for user to run in a new terminal window
Inform user - Tell them how to monitor progress
Exit - HOUSTON's job is done, Ralph takes over

Launch Command

bash skills/mission-ralph/scripts/ralph.sh FEATURE_ID &

Or with visible mode (mprocs TUI):

bash skills/mission-ralph/scripts/ralph.sh FEATURE_ID --visible

What Ralph Does

Ralph spawns fresh Pods for each task in a loop:

Get next ready task via bd ready
Spawn Pod (Scout -> Worker -> Inspector -> Analyst -> Airlock)
Handle result (complete, retry, or create blocking bug)
Continue until no tasks remain or critical halt

Each Pod includes a Scout phase that gathers codebase context before Worker executes.

User Communication

If background mode:

HOUSTON: Ralph loop launched for feature FEATURE_ID.

         Ralph runs automatically in background.
         Check progress: /capcom

         You'll be notified on:
         - Feature completion
         - Critical blocker (requires intervention)

         Safe to close this session.

If visible mode:

HOUSTON: Run this command in a new terminal window:

         bash skills/mission-ralph/scripts/ralph.sh FEATURE_ID --visible

         This opens mprocs with live task progress.
         Check status anytime: /capcom

Monitoring

/capcom - Check feature status and task progress
bd list --parent FEATURE_ID - See all tasks
bd ready - See what's next in queue
bd dep tree FEATURE_ID - See task hierarchy and status

Exit Codes

Code	Meaning
0	Feature complete
1	Critical blocker - check `/capcom`
2	Configuration error
