debug-agent

debug-agent is a command for Claude Code from latestaiagents/agent-skills. It costs 8 tokens per session (348 once invoked), scanned A, original, MIT.

A command for finding and fixing problems in systems where several AI agents work together.

In plain words
What is it for?
Use it to investigate agent loops, wrong routing, lost state, tool failures, timeouts, and inconsistent results.
Why use it?
It provides a structured way to trace unexpected behavior, identify root causes, and verify fixes.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00008 $0.00348
Opus 5.5 $0.00003 $0.00139
Sonnet 5.5 $0.00002 $0.00070

Security

Grade A, and why

debug-agent 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 it actually says

/debug-agent

Diagnose and fix issues in your multi-agent system.

What I Need

Tell me:

  • What's the unexpected behavior?
  • Which agent(s) are involved?
  • Do you have traces/logs?
  • Is it reproducible?

Debug Process

Step 1: Identify Failure Point

I'll help locate:

  • Which agent failed
  • At what step in the workflow
  • What was the input/output

Step 2: Analyze Root Cause

Common issues:

  • Prompt ambiguity
  • Tool execution failures
  • State corruption
  • Infinite loops
  • Token limit exceeded

Step 3: Trace Analysis

If using LangSmith:

from langsmith import Client
client = Client()
runs = client.list_runs(project_name="your-project", error=True)

Step 4: Fix & Verify

I'll provide:

  • Specific fix for the issue
  • Test case to verify
  • Prevention measures

Common Issues

Symptom Likely Cause Fix
Agent loops forever No exit condition Add max_iterations
Wrong agent selected Poor routing Improve router prompt
State lost Missing checkpointer Add persistence
Timeout Agent stuck Add timeout + fallback
Inconsistent results Non-deterministic Set temperature=0

Debug Checklist

[ ] Check agent prompts for ambiguity
[ ] Verify tool definitions are correct
[ ] Inspect state at each transition
[ ] Review routing logic
[ ] Check for token limits
[ ] Verify checkpointing works
[ ] Test edge cases

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.
