diagnose

diagnose is a skill for Claude Code from eduwxyz/my-awesome-skills. It costs 0 tokens per session (2,088 once invoked), scanned A, original, no licence file.

A bug-diagnosis skill that turns a reported symptom into a fix and a regression test. A regression test is an automated check that helps ensure the same bug does not return.

In plain words
What is it for?
It is for investigating bugs, asking focused questions, reproducing failures, implementing fixes, and adding tests that cover them.
Why use it?
It guides investigation when a bug report is vague, requires reproduction before fixing, and records the fix in a test when possible.

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

diagnose 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The deterministic trigger from Phase 1. A test name, a curl, a script — whatever the loop is.

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.
