The file
We split this skill into the rules it gives an agent
4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
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 13
Keep feature flags or compatibility shims when risk is high.
- Distinctive: line 14
Remove dead legacy code only after verification.
- Distinctive: line 18
Do not big-bang rewrite when incremental is possible.
- Distinctive: line 20
Document interim dual-path states and the removal criteria.
≈ “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.
Files
Migrate Code
Strategy
- Inventory call sites and compatibility constraints.
- Choose expand/contract: add new path, dual-write/read if needed, remove old path last.
- Migrate in thin vertical slices that stay shippable.
- Keep feature flags or compatibility shims when risk is high.
- Remove dead legacy code only after verification.
Rules
- Do not big-bang rewrite when incremental is possible.
- Preserve behavior with characterization tests before moving logic.
- Document interim dual-path states and the removal criteria.
- Match the target pattern already established in the repo when one exists.
Exit Criteria
- Old path unused or clearly deprecated
- Tests cover migrated behavior
- Rollback approach known
Does it work?
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.
- It worked
- Partly
- It didn't
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.
