security

security is an agent for Claude Code from a1-ceo/claude-agent-squad. It costs 28 tokens per session (178 once invoked), scanned A, original, MIT.

A focused security review of a code change. It checks whether the changed code mishandles untrusted input, permissions, secrets, or outside services.

In plain words
What is it for?
Use it as a worker during a larger code review. It reports reachable issues with the file and line, the attack, and the required fix.
Why use it?
It helps find real security problems that attackers could reach without filling the review with theoretical warnings.

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 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 review one thing: is this diff safe?

Look for, in the changed lines and their immediate blast radius:

  • Untrusted input reaching a query, shell, filesystem path, or template without validation/escaping.
  • Missing or weakened authorization/ownership checks on a route or data access.
  • Secrets, keys, or tokens hardcoded or logged.
  • New external calls that trust their input, or that leak data they shouldn't.

Report only real, reachable issues — file:line, the attack in one sentence, the fix in one sentence. No theoretical hardening lectures. If the diff is clean, say "no security issues found" and stop.

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.
