What it does
Systematic Debugging is an agent skill from ed3dai/ed3d-plugins. Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `CREATION-LOG.md`, `test-academic.md` and `test-pressure-1.md`).
It sits in Development, covering Debugging, Root cause analysis and Failing and flaky tests. The repository describes itself as: Ed's repo of Claude Code plugins, centered around a research-plan-implement workflow. Only a tiny bit cursed. If you're lucky.
When your agent uses it
- Encountering any bug
- Unexpected behavior
- Before proposing fixes - four-phase framework (root cause investigation
- Pattern analysis
Example prompts
- “/systematic-debugging”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Root Cause Investigation
- Pattern Analysis
- Hypothesis and Testing
- Implementation
What it can do on your machine
Read from SKILL.md and the folder at commit 0c90f4b. 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 bash).
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 2.4k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 1,136 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,136 words (~2,434 tokens).
“Random fixes waste time and create new bugs. Quick patches mask underlying issues.”
