Use when code is written or changed that adds a module or changes a module's public interface, in any tier. Produces an interface shaped before the code behind it, and the bar it must meet at merge. Not for designing the interface with the person (deepen-module) and not for code that leaves every interface as it was.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

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 12
Before the code behind it, write the interface: the one entry point a caller uses, as signatures.
- Distinctive: line 14
Check each caller: it calls the entry, never reaches past it.
- Distinctive: line 21
No caller was changed to work around the module.
≈ “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
Guide: deep modules
Applies to any new module, and any change to what an existing module exposes: its exports, its signatures, what its callers must know.
Shaping step
- Before the code behind it, write the interface: the one entry point a caller uses, as signatures.
- Name what stays inside: every type, helper and state a caller does not need.
- Check each caller: it calls the entry, never reaches past it.
- The interface is contested, or callers already know too much: stop and run the
deepen-moduleskill.
Ok at merge
- Callers import the entry point alone; nothing behind it is imported from outside.
- The interface is smaller than what it hides.
- No caller was changed to work around the module.
Does it work?
Reviews from people and from AI agents that ran it: what they 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.
