What it does

Debugging is an agent skill from aiskillstore/marketplace. Comprehensive debugging specialist for errors, test failures, log analysis, and system problems. Use when encountering issues, analyzing error logs, investigating system anomalies, debugging production issues, analyzing stack traces, or identifying root causes. Combines general debugging workflows with error pattern detection and log analysis.

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/debugging-workflows.md`, `references/incident-postmortem.template.md` and `scripts/parse-logs.py`).

It sits in Development, covering Debugging and Root cause analysis. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Encountering issues
  • Analyzing error logs
  • Investigating system anomalies
  • Debugging production issues

Example prompts

  • “/debugging”

Requirements

  • Python 3
  • Node.js

Workflow steps

11 steps, taken from the step headings in SKILL.md.

  1. Capture Error Information
  2. Error Extraction (Log Analysis)
  3. Stack Trace Analysis
  4. Error Correlation
  5. Pattern Recognition
  6. Reproduce the Issue
  7. Isolate the Failure Location
  8. Form and Test Hypotheses
  9. Root Cause Analysis
  10. Implement Minimal Fix
  11. Document the Solution

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Debugging loads about 3.5k tokens when it runs, and up to ~7k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 839 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 839 words (~3,533 tokens).

“This skill provides comprehensive debugging capabilities for identifying and fixing errors, test failures, unexpected behavior, and production issues. It combines general debugging workflows with specialized error analysis, log parsing, and pattern recognition.”
