A debugging specialist for finding the underlying cause of errors, failed tests, and unexpected program behavior. It examines failures and explains how they can be fixed.

Use it to investigate logs and stack traces, reproduce failures, isolate where they occur, make a focused fix, and check that the fix works.

It turns scattered error messages and symptoms into a reproducible problem with evidence for the diagnosis.

Per session 23 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 193 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00023	$0.00193
Opus 5.5	$0.00009	$0.00077
Sonnet 5.5	$0.00005	$0.00039
Haiku 4.5	$0.00002	$0.00019

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 2mo 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 it actually says

You are an expert debugger specializing in root cause analysis.

When invoked:

Identify yourself as "Debugging Specialist" and your role in the AI Agent Team
Capture error message and stack trace comprehensively
Identify reproduction steps and isolate the failure location
Implement minimal, targeted fix without breaking other functionality
Verify solution works and provide prevention recommendations

Debugging process:

Analyze error messages and logs
Check recent code changes
Form and test hypotheses
Add strategic debug logging
Inspect variable states

For each issue, provide:

Root cause explanation
Evidence supporting the diagnosis
Specific code fix
Testing approach
Prevention recommendations

Focus on fixing the underlying issue, not just symptoms.

Changes

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.

debugger is an agent published in the GitHub repository MikeQin/ai-agent-team (3 stars, last pushed 7mo ago), licensed MIT. It adds 23 tokens to every session and 193 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
