audit-codebase

audit-codebase is a skill for Claude Code, Codex from AleksandarBisevac/claude-plugins. It costs 88 tokens per session (493 once invoked), scanned A, original, MIT.

A guide for auditing an entire codebase as tracked, resumable work. A codebase is the full collection of source code and related files in a project; the audit uses phases recorded in an audit plan.

In plain words
What is it for?
It is for starting an audit, checking its status, finding the next phase, running a phase, or diagnosing problems in a repository-wide cleanup.
Why use it?
It prevents a large cleanup from becoming an untracked one-off review and makes it possible to resume, inspect progress, or diagnose a blocked phase.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the audit plugin — 2 skills, 20 commands, 4 agents, 6 hooks shipped together

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

audit-codebase 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 4d 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

Auditing a codebase with the audit plugin

This skill exists to be found, not to explain anything. Everything it knows is one of three files; read the one that matches and follow it exactly.

Do not use this for

A one-shot review of the working diff or a pull request. /review, /security-review and the native code-review tooling are the right answer there, and reaching for a manifest to look at ten changed lines is pure overhead. This is for work that spans sessions and has to survive being interrupted.

Route

Check for a manifest first — docs/audit/audit-plan.json by default, or manifestPath in .claude/audit.config.json.

Situation Command
No manifest yet /audit:init — generates one from the codebase
A manifest exists, and the question is "where are we" /audit:status
A manifest exists, and the question is "what now" /audit:next
Run the next phase end to end /audit:phase <id>
Something is not working and it is not obvious why /audit:doctor

Read ${CLAUDE_PLUGIN_ROOT}/commands/<name>.md and do what it says. Those files are the source of truth; nothing here restates their procedure, because two copies of a procedure is one copy and one lie.

The one thing worth knowing before starting

/audit:init spawns several agents and is the most expensive command here. If the person has not committed to the pipeline yet, /audit:usage --backfill costs nothing, reads transcripts already on disk, and shows them what their existing work has cost — see the audit-spend skill. That is a better first move than a manifest they did not ask for.

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.

audit-codebase is a skill published in the GitHub repository AleksandarBisevac/claude-plugins (4 stars, last pushed 3d ago), licensed MIT. It adds 88 tokens to every session and 493 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
