audit-deep-logic

audit-deep-logic is a skill for Claude Code from daanvandenbergh/claudekit. It costs 0 tokens per session (7,704 once invoked), scanned A, original, no licence file.

A whole-codebase review that looks for deep logic bugs at the boundaries between modules, where separate parts of a system interact. It checks whether shared rules and assumptions stay true across different paths.

In plain words
What is it for?
Use it to audit cross-module contracts, invariants, deletion cascades, tenant scoping, and other system-wide behavior.
Why use it?
It can reveal failures that a file-by-file review misses, such as inconsistent deletion behavior or missing tenant restrictions on one route.

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-deep-logic 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 12d 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 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.
