Convert PRDs to prd.json format for the Ralph autonomous agent system. Use when you have an existing PRD and need to convert it to Ralph's JSON format. Triggers on: convert this prd, turn this into ralph format, create prd.json from this, ralph json.
npx skills add majiayu000/claude-skill-registry --skill ralph-glowfinger-tagging-rugby-cli --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Ralph PRD Converter Converts existing PRDs to the prd.json format that Ralph uses for autonomous execution. --- ## The Job Take a PRD (markdown file or text) and convert it to `prd.json` in your ralph directory. --- ## Output Format ```json { "project": "[Project Name]", "branchName": "ralph/[feature-name-kebab-case]", "description": "[Feature description from PRD title/intro]", "userStories": [ { "id": "US-001", "title": "[Story title]", "description": "As a [user], I want [feature] so that [benefit]", "acceptanceCriteria": [ "Criterion 1", "Criterion 2", "Typecheck passes" ], "priority": 1, "passes": false, "notes": "" } ] } ``` --- ## Story Size: The Number One Rule **Each story must be completable in ONE Ralph iteration (one context window).** Ralph spawns a fresh Amp instance per iteration with no memory of previous work. If a story is too big, the LLM runs out of context before finishing and produces broken code. ### Right-sized stories: - Add a database column and migration - Add a UI component to an existing page - Update a server action with new logic - Add a filter dropdown to a list ### Too big (split these): - "Build the entire dashboard" - Split into: schema, queries

Run `npx skills add majiayu000/claude-skill-registry --skill ralph-glowfinger-tagging-rugby-cli --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
