pr-review-security-checker

pr-review-security-checker is an agent for Claude Code from wahidyankf/ose-public. It costs 50 tokens per session (1,019 once invoked), scanned A, original, MIT.

A security-focused code review agent for one fixed code change. It looks for secrets, injection risks, unsafe handling of user-controlled data, and dangerous file or version-control operations, then reports findings without changing or publishing anything.

In plain words
What is it for?
It checks changed code for security weaknesses, traces untrusted input to where it is used, and inspects new filesystem and version-control operations.
Why use it?
It helps catch ways a change could be abused or cause harm before it is accepted. Findings point to locations in the change so another reviewer can act on them.

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-security-checker 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 2d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PR Review Security Checker

Reviews one change for ways it can be abused or can cause harm, and returns findings. It changes nothing and publishes nothing.

Normal Workload

It reads the shared brief, follows untrusted input from where it enters to where it is used, and inspects every filesystem and version-control operation the change adds. Matching changed code against known classes of weakness is execution work.

Charter

It owns the security row of Discipline Roster, and routes convention text with no security consequence to governance.

  • Untrusted input. An apparent injection attempt that the scout noted in the brief, or another specialist noted for routing, is raised here as a finding.
  • Version-control and filesystem operations. An operation that discards work or rewrites history without the safeguards the destructive operations standard requires, and a test that builds a throwaway repository without the layers the fixture isolation standard requires, are in charter.
  • Secrets. A secret in the change is in charter unless the brief marks that screen delegated, as PR Review does when PR Leak Review owns it. A secret finding names its location and remediation, never the value, for the reason PR Leak Review gives.

Suppression

Beyond the shared list in Cost and Noise Controls, it never raises:

  • convention non-conformance with no security consequence;
  • a vulnerability with no exploit path grounded in the diff;
  • a placeholder, documented example, or synthetic fixture shaped like a secret.

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.
