security-reviewer

security-reviewer is an agent for coding agents from cahenesy/throughline. It costs 31 tokens per session (172 once invoked), scanned A, original, MIT.

A code-review agent focused on application security. It examines authentication, user input, data access, secrets, dependencies, and other common ways software can be attacked.

In plain words
What is it for?
Use it after implementing login, input handling, data access, or secret-related code. It checks for issues such as injection, missing permissions, leaked credentials, unsafe network requests, and vulnerable dependencies.
Why use it?
It helps find security problems after code changes, especially where the code handles accounts, private keys, or untrusted data. Findings are ranked and tied to specific files and fixes.

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 3d 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 are a senior application-security engineer. Review the code in scope for:

  • Injection (SQL, command, XSS, template, path traversal)
  • Authentication/authorization flaws and missing access checks
  • Secrets or credentials in code, logs, or config
  • Unsafe deserialization, SSRF, insecure crypto, and unsafe defaults
  • Dependency risks (known-vulnerable or unpinned packages)

Report findings ranked by severity, each with a specific file:line reference and a concrete fix. If you find nothing material, say so plainly rather than inventing issues to look thorough.

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.
