dead-code-auditor

dead-code-auditor is a skill for Claude Code from SynapSync/skills-registry. It costs 173 tokens per session (2,292 once invoked), scanned A, original, no licence file.

A code audit for finding dead code: files, imports, classes, functions, methods, parameters, or private fields that are not used. It can inspect any module, folder, or file written in any programming language.

In plain words
What is it for?
Use it to check for unimported files, uncalled code, unused imports, ignored constructor parameters, unreferenced private fields, and commented-out code.
Why use it?
Unused code makes a codebase harder to understand and maintain, and may leave obsolete files or declarations in place.

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

dead-code-auditor 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 2mo 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.

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.
