debug-helper

debug-helper is a skill for Claude Code, Codex from ifiokjr/monopi. It costs 28 tokens per session (342 once invoked), scanned A, original, MIT.

A debugging guide for analyzing errors, logs, crashes, and slow programs. It lays out a process from reading the failure and locating its source to reproducing, fixing, and verifying the result.

In plain words
What is it for?
Use it to inspect stack traces and logs, find relevant code, create minimal reproductions, profile Node.js, Python, or Go programs, and verify fixes or optimizations.
Why use it?
It helps turn vague error messages or performance complaints into a traceable investigation with a measured baseline and a confirmed cause.

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-helper 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 6d 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 Helper

Systematic debugging workflow.

Error Analysis

  1. Read the error: full stack trace and error message
  2. Locate: find the source file and line
    # Search for the error origin
    grep -rn "ErrorClass\|error_function" src/
    
  3. Context: read surrounding code (±30 lines)
  4. Reproduce: identify minimal reproduction steps
  5. Root cause: trace the data flow to find where it goes wrong
  6. Fix: minimal change that addresses the root cause
  7. Verify: run the failing case to confirm the fix

Log Analysis

  1. Read the log file or output
  2. Identify patterns: timestamps, error levels, request IDs
  3. Correlate events across log lines
  4. Summarize: what happened, when, and why

Performance Profiling

  1. Measure: get baseline numbers first
    time <command>
    
  2. Profile: use language-appropriate tools:
    • Node.js: --prof, clinic.js
    • Python: cProfile, py-spy
    • Go: pprof
  3. Identify: find the hotspot (usually 1-2 functions)
  4. Optimize: fix the bottleneck
  5. Verify: measure again, compare with baseline

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.
