ralph-github

ralph-github is a skill for Claude Code from rubenmarcus/ralph-starter. It costs 15 tokens per session (215 once invoked), scanned A, original, MIT.

A tool that takes a GitHub issue or pull request—GitHub’s records for work and code changes—and turns its requirements into a coding task. It can run an automated build process for the task.

In plain words
What is it for?
Use it to fetch an issue or pull request, filter work by repository or label, implement one task, or process several tasks with separate branches and pull requests.
Why use it?
It removes the manual work of copying requirements from GitHub into a coding workflow and setting up separate work for each issue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ralph-github scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fetch specs from GitHub issues or PRs and run an autonomous coding loop to implement them.

  1. Use ralph_fetch_spec with source: "github" to preview the issue/PR:

    • identifier: repo URL, "owner/repo#123", or issue URL
    • Use project to filter by repo, label to filter by label
  2. Use ralph_run to build from the spec:

    • Set from: "github" and provide project (owner/repo)
    • Optionally filter with label (e.g., "good first issue", "bug")
    • Set auto: true, commit: true, validate: true for full automation
  3. For batch processing multiple issues, use ralph_run with auto: true — each issue gets its own branch and PR.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
