What it does
Systematic Debugging is an agent skill from rileyhilliard/claude-essentials. Debugging framework that finds root causes before proposing fixes. Use when investigating bugs, errors, unexpected behavior, failed tests, or when previous fixes haven't worked.
Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/debugging-techniques.md`).
It sits in Development, covering Debugging and Root cause analysis. The licence is MIT.
When your agent uses it
- Investigating bugs
- Unexpected behavior
- Previous fixes havent worked
Example prompts
- “/systematic-debugging”
What it can do on your machine
Read from SKILL.md and the folder at commit 3a67a01. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
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
Systematic Debugging loads about 358 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 102 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.

- description
- Debugging framework that finds root causes before proposing fixes. Use when investigating bugs, errors, unexpected behavior, failed tests, or when previous fixes haven't worked.
If the current repo has its own rules/skills covering this topic (check .claude/rules/ and repo CLAUDE.md), those take precedence — apply this skill only where they're silent.
Systematic Debugging
If 3+ fixes have failed: Stop fixing symptoms. Question the architecture. The bug may be a design problem, not a code problem.
For multi-component systems: Add diagnostic logging at each component boundary before proposing fixes. See references/debugging-techniques.md for instrumentation patterns (binary search, git bisect, minimal reproduction, strategic logging, differential analysis).
For large or multi-file log investigations: Delegate to the @ce:log-reader agent for efficient analysis. Not needed for a single short stack trace.
Reporting Format
## Root Cause
[1-3 sentences explaining underlying issue]
Located in: `file.ts:123`
## What Was Wrong
[Specific problem - mutation, race condition, missing validation, etc. 1-3 sentences]
## The Fix
[Changes made and why they address root cause. 1-3 sentences]
## Verification
[How the fix was confirmed - e.g. reran the failing test, reproduced and retested manually]© rileyhilliard, MIT. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
