debugger

debugger is an agent for Claude Code from haposoft/cafekit. It costs 37 tokens per session (1,639 once invoked), scanned A, original, no licence file.

A debugging and incident-investigation coding agent that examines failures in code, continuous integration, logs, databases, performance, and front-end behaviour to find their exact causes.

In plain words
What is it for?
Use it to investigate bugs, production incidents, failing builds, slow systems, database problems, and front-end failures, then produce a fix plan that can be checked.
Why use it?
It replaces guesswork with evidence about what went wrong, while leaving the repair itself to another step or person.

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

debugger 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 2d 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.

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.
