What it does
08 Debug is an agent skill from ai-driven-dev/framework. Reproduce and fix a known bug, or find an unknown root cause by hypothesis validation. Use when the user wants to fix a bug, find why something breaks, or reopen a stuck investigation. Not for building a feature or reviewing a diff.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files and assets (for example `actions/01-reproduce.md`, `actions/02-debug.md` and `actions/03-reflect-issue.md`).
It sits in Development, covering Root cause analysis. The repository describes itself as: Marketplace Framework AI-Driven Dev : Context Engineering, Plugins, Agents, Skills, Hooks, Templates, SDLC. The licence is MIT.
When your agent uses it
- The user wants to fix a bug
- Find why something breaks
- Reopen a stuck investigation
Example prompts
- “/08-debug”
What it can do on your machine
Read from SKILL.md and the folder at commit 6e30640. 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.
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
08 Debug loads about 442 tokens when it runs, and up to ~720 if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 176 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: debug
Diagnose and fix issues through structured hypothesis validation, root-cause analysis, and a test-driven fix.
Actions
| # | Action | When to use |
|---|---|---|
| 01 | reproduce | A known bug must be fixed end to end: reproduce, test-driven fix, branch, PR |
| 02 | debug | Root cause unknown: enumerate hypotheses, validate each, confirm the cause |
| 03 | reflect-issue | Stuck or prior fixes failed: reopen the search space, instrument logs first |
Pick the one action matching the intent; never default to 01. Triggers like "reproduce and fix" route to 01, "why does this happen" to 02, "I'm stuck" or "previous fixes didn't work" to 03. Ask one question when the intent is ambiguous. Before running an action, read its file in actions/, not only the table or assets.
Transversal rules
- One action per run: follow only the matching action file.
- Scope each fix to its bug: never bundle drive-by refactors.
- Confirm the root cause before fixing; the diagnostic actions stop at a confirmed cause.
Assets
assets/task-template.md: the per-hypothesis tracking file the debug action fills.
References
