The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 19
Delete only safe set; run tests/typecheck.
- Distinctive: line 20
If maybe: quarantine with comment or feature-owner ask — don’t guess.
- Distinctive: line 31
Delete because “agent says unused” without search
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Dead Code Safe Delete
Overview
AI leaves unused helpers. Delete only with evidence of non-use; prefer small PRs.
Steps
- Candidate list (files/symbols).
- Evidence: search references, exports, dynamic imports, routes, reflection.
- Mark: safe-delete | maybe (dynamic) | keep.
- Delete only safe set; run tests/typecheck.
- If maybe: quarantine with comment or feature-owner ask — don’t guess.
Exit criteria
- Evidence per candidate
- Only safe items removed (or none)
- Tests/typecheck plan
- Maybes not deleted silently
Anti-patterns
- Delete because “agent says unused” without search
- Huge delete mix with features

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
