ralph-validate

ralph-validate is a skill for Claude Code, Codex from rubenmarcus/ralph-starter. It costs 15 tokens per session (121 once invoked), scanned A, original, MIT.

A project-validation skill that detects and runs available tests, code checks, and build commands.

In plain words
What is it for?
Use it to validate projects with package scripts, Makefile targets, or common test, lint, and build setups.
Why use it?
It provides a repeatable check that the project still works after changes, without requiring you to remember every validation command.

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-validate 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 5d 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

Run all detected validation commands for a project.

  1. Use ralph_validate with the project path
  2. Auto-detects validation commands from:
    • package.json scripts (test, lint, build)
    • Makefile targets
    • Common patterns for the detected project type
  3. Returns pass/fail status with output for each command

Use ralph_status first to check the overall project state and implementation plan progress.

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.
