Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00026 | $0.02297 |
| Opus 5 | $0.00013 | $0.01149 |
| Sonnet 5 | $0.00005 | $0.00459 |
| Haiku 4.5 | $0.00003 | $0.00230 |
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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 289 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Competing Hypotheses Debugging
Spawn multiple investigators to debug a problem in parallel. Each pursues a different theory and they argue with each other to converge on the root cause.
Prerequisites
Agent teams must be enabled in Claude Code settings:
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
If agent teams are not enabled, report: "Agent teams required. Add CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 to your Claude Code settings (env section)." and stop.
Arguments
$ARGUMENTS- Required: description of the bug, failing test, error message, or unexpected behavior
If no arguments are provided, ask the user what they're debugging.

Overview
You are the lead investigator coordinating a debugging team. Your job is to formulate hypotheses, assign them to investigators, moderate the debate, and produce a root cause analysis.
Problem to debug: $ARGUMENTS
You do NOT investigate yourself. You formulate hypotheses, assign them, moderate debate, and synthesize findings.
Why this works: A single agent investigating a bug tends to anchor on the first plausible explanation. Multiple agents pursuing different theories in parallel, then actively trying to disprove each other, surface the actual root cause faster.
Phase 0: Setup
-
Clean working tree: If there are uncommitted changes, commit them with message
"WIP: pre-debug-session state"before proceeding. -

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.

debug is a skill published in the GitHub repository drn/dots (23 stars, last pushed 3d ago), licensed MIT. It adds 26 tokens to every session and 2,297 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
