pr-review

pr-review is a skill for Claude Code, Codex from thejefflarson/soundcheck. It costs 59 tokens per session (798 once invoked), scanned A, original, MIT.

A fast security gate for pull requests, which are proposed code changes for review. It examines only changed files and reports Critical and High severity issues from OWASP and AI-security categories.

In plain words
What is it for?
Use it in pull-request CI to check changed code for issues such as injection, path traversal, missing CSRF protection, unsafe redirects, server-side request forgery, and newly added secrets.
Why use it?
It gives CI a focused check that can block serious vulnerabilities before a change is merged. It is designed for small diffs and does not perform the deeper threat modeling or attack-chain analysis used by larger reviews.

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

pr-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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pull Request Security Gate (A01:2025–A10:2025 + LLM01:2025–LLM10:2025)

What this checks

Fast single-pass review of the files in a pull request diff. Reports only Critical and High severity findings. Designed for CI: completes in seconds-to-minutes on haiku, well under the time a developer expects to wait on a PR check. This is the per-PR gate. For nightly or deep audits, reach for security-review or contract-review.

Vulnerable patterns

Soundcheck's per-category skills (injection, csrf, ssrf, broken-access-control, authentication-failures, hardcoded-secrets, path-traversal, prompt-injection, …) auto-invoke when their description matches code in the diff. Examples this gate is expected to catch on a routine PR:

  • SQL or shell string built from request data — injection
  • Path opened from a URL parameter without normalization — path-traversal
  • A new credential string-literal in a config file — hardcoded-secrets
  • A new state-changing endpoint without csrfProtectioncsrf
  • A new fetch to a caller-supplied URL with no host allowlist — ssrf

Procedure

This skill is the coordinator — it does the reading; per-category skills supply the patterns. No subagents.

- [ ] Read every file in the supplied changed-file list once
- [ ] Apply soundcheck's per-category skills as their descriptions match
- [ ] Filter findings to severity Critical or High
- [ ] Emit findings table only (no chains, no design review)
- [ ] Append the machine-readable <soundcheck-findings>[...] block

For each finding, the table row contains:

| Severity | File:Line | Skill | Finding | Fix |

  • Severity is Critical or High; drop Medium and Low.
  • File:Line must be inside the supplied changed-file list.
  • Skill names the auto-invoking soundcheck skill the pattern matched.
  • Finding is one short sentence a non-security developer can act on.
  • Fix is one short sentence; link or quote the secure pattern from the relevant skill's Fix immediately block.

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.

pr-review is a skill published in the GitHub repository thejefflarson/soundcheck (20 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 798 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 2026-08-30.
