async-debugging-specialist

A debugging assistant for asynchronous code, where tasks can run independently, and concurrency issues, where tasks overlap or interact unexpectedly.

In plain words
What is it for?
Use it to investigate problems in asynchronous programs and concurrent code.
Why use it?
It helps trace bugs that depend on timing, task order, or interactions between simultaneous operations.

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

async-debugging-specialist scanned grade A with 1 finding 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 3d 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.

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.

writing-skills

The skills under skills/ are staged into a sandbox and run autonomously against a target repo — no human is in the loop mid-run. A skill exists to wrangle determinism out of a stochastic agent: the goal is predictability, the agent taking the same process every run (not producing the same output). Everything below…
