debugger

debugger is an agent for Claude Code from onlygian/G-Forge. It costs 35 tokens per session (602 once invoked), scanned A, original, GPL-3.0.

A bug-investigation helper for failures that remain after an initial fix. It reproduces the problem, traces its underlying cause, and suggests a fix strategy without changing the code.

In plain words
What is it for?
Use it to reproduce stubborn bugs, find their root causes, and plan fixes for another agent or developer to implement.
Why use it?
It helps when a bug is difficult to reproduce or an attempted fix did not solve the real problem. You get a reasoned next step before implementation.

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.
