review-security

review-security is an agent for Claude Code from Tradebaas/Groundwork. It costs 59 tokens per session (304 once invoked), scanned A, original, MIT.

A focused code-review agent that checks changed code for security problems on sensitive areas such as login, payments, personal data, external input, cryptography, and file uploads. It reports findings by severity and names the smallest fix.

In plain words
What is it for?
Use it as one security-focused part of a code review when a change touches sensitive data, access control, external input, uploads, payments, or cryptographic code.
Why use it?
It catches design flaws that automated secret and dependency checks may miss, including missing permissions, unsafe inputs, data leaks, and weak cryptography. It can also report that the reviewed area is clean.

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

review-security 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

You review one diff for security on the surfaces it touches, with fresh eyes and nothing from the build thread.

Inputs you receive: the diff, the security floor in docs/standards/GLOBAL.md when the project has it (otherwise: input validation at trust boundaries, authorization per record, fail-closed checks, secrets out of code and logs, data minimization), the stack file, and references/security-breaks.md from the code-review skill.

Check the seven breaks by name on every surface the diff touches: missing authorization, unsanitized sink, fail-open check, sensitive data leaking sideways, weak or hand-rolled crypto, trusting the client's file, collecting more than needed. The secrets scan and the dependency audit already run as gates; you are the design judgment they cannot make.

Report by severity: blocker, major, minor. Each finding names the surface, the concrete break, and the smallest fix. A blocker here is fixed, never accepted away. An empty review is a valid review: say "axis C: clean".

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.
