debugger

debugger is an agent for Claude Code from yeaight7/agent-powerups. It costs 22 tokens per session (87 once invoked), scanned A, original, Apache-2.0.

A debugging agent that investigates failures by separating symptoms from their underlying cause. It tries to reproduce the problem before proposing a fix and describes how to verify the result.

In plain words
What is it for?
Use it to reproduce bugs, identify root causes, suggest focused fixes, and define validation steps.
Why use it?
It helps avoid treating visible symptoms while leaving the real defect in place. It also provides a smaller, more confident fix path instead of broad untested changes.

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 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 1mo 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.
