audit-blocking-io-async is a skill for Claude Code, Codex from danygiguere/audit-skills. It costs 64 tokens per session (139 once invoked), scanned A, original, MIT.

A code-review checklist for finding operations that block asynchronous programs, such as network calls, file access, pauses, or heavy calculations.

In plain words
What is it for?
Use it to review async handlers, coroutine code, event-loop services, and worker pools, then report verified issues with severity and file locations.
Why use it?
It helps prevent slow responses, stalled event loops, and services that stop handling other work while waiting.

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-blocking-io-async 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/operability/blocking-io-async.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.
