debug

debug is a skill for Claude Code, Codex from arbiterForge/codeArbiter. It costs 68 tokens per session (2,197 once invoked), scanned A, original, AGPL-3.0.

A guided investigation process for finding the root cause of a defect when the cause is not yet known. It gathers evidence and produces a decision without changing code.

In plain words
What is it for?
Use it to capture a bug, test possible explanations, collect evidence, decide what was found, and hand the result to a fix or decision workflow.
Why use it?
It separates diagnosis from fixing, reducing the risk of changing code before the actual problem is understood.

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

debug 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 5d 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.
