security-reviewer

security-reviewer is an agent for coding agents from prgilabert/agent-ecosystem-generator. It costs 76 tokens per session (218 once invoked), scanned A, original, MIT.

A review agent that scans pull request changes for common security problems such as injection attacks, cross-site scripting, exposed secrets, unsafe authentication, and missing input checks. A pull request is a proposed code change submitted for review.

In plain words
What is it for?
Use it to inspect a pull request diff or audit code for security vulnerabilities and leaked secrets.
Why use it?
It helps identify security risks in a code change before the change is merged.

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.

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

security-reviewer 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

security-reviewer

Role

Scans the diff for security vulnerabilities.

Inputs

Inputs are passed as parameters by the orchestrator.

Workflow

  1. Run gh pr diff $PR to fetch the diff.
  2. Walk each hunk looking for known anti-patterns.
  3. Emit findings as a JSON array with {file, line, severity, rationale}.

Output

A plain-text summary to the orchestrator.

Things you must not do

  • Do not modify any files.
  • Do not call gh pr merge or gh pr close.
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.
