codebase-audit

A broad review of a codebase that uses many focused checks to look for problems in Python, React, Go, documentation, and website files.

In plain words
What is it for?
Use it to inspect a whole repository, collect findings, and decide which problems to address first.
Why use it?
It helps uncover issues across a large project instead of relying on one manual review. The results are saved for discussion and sorting with the user.

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 B, and why

codebase-audit scanned grade B with 2 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 yesterday.

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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

RUN_DIR="_audit/runs/$(date +%Y-%m-%d-%H%M%S)-$$" && mkdir -p "$RUN_DIR/findings" && if test -d _audit/latest && ! test -L _audit/latest; then rm -rf _audit/latest; else rm -f _audit/latest; fi && ln -sfn "runs/$(basenam

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Expected in a hook, worth knowing in a rule or an instructions file.

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.

codebase-audit is a skill published in the GitHub repository Aureliolo/synthorg (9 stars, last pushed yesterday), with no licence file. It adds 44 tokens to every session and 47,665 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (recursive force delete, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
