audit-injection

audit-injection is a skill for Claude Code, Codex from danygiguere/audit-skills. It costs 36 tokens per session (108 once invoked), scanned A, original, MIT.

A security review checklist for code that puts user-provided values into database queries, shell commands, templates, or file paths.

In plain words
What is it for?
Use it to inspect specified code or the current changes, verify possible injection issues, and report their severity with file and line references.
Why use it?
It helps find injection risks, where input is interpreted as part of a command or query instead of ordinary data.

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

audit-injection 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 11d 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

Read ../audit/references/input-api-dependency/injection.md and apply its checklist to the code the user specified (or the current diff if none was given). Verify each candidate with ../audit/references/methodology/verify.md before reporting. Report findings with severity and file:line references.

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.
