Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.00296 |
| Opus 5 | $0.00030 | $0.00148 |
| Sonnet 5 | $0.00012 | $0.00059 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
ralph-review 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 11d 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
Ralph Review
Review the sprint as an evidence-backed delivery unit.
- Read repository instructions, the durable spec, sprint
README.md,IMPLEMENTATION_PLAN.md,relevant-specs.md,chunks.json, andSCRATCHPAD.md. - Inspect the actual commit range and changed artifacts. Do not accept summaries as proof.
- Verify every passed chunk against its acceptance criteria, validation logs, and commit evidence.
- Check final review, documentation, sprint-validation, and optional E2E hook states. Distinguish skipped, failed, interrupted, and completed hooks.
- Look for missing spec behavior, accidental scope, weak tests, stale documentation, unsafe orchestration state, and negative knowledge the next sprint must preserve.
- Report findings by severity, then give a clear verdict: complete, repairable before acceptance, or blocked. Name the exact evidence and next action.
Do not rewrite chunk state, manufacture evidence, or implement findings during a review-only request.
When installed beside $ralph-loop, consult references/review.md for the full shared rubric.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ralph-review is a skill published in the GitHub repository zacharygcook/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 296 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
