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
2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 8 edited versions we read keep these.
2
Distinctive
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 8
Write the shape before the handlers.
- Distinctive: line 25
Do not add a service, a queue, or a second database until a route needs it.
“Common” is measured: kept by at least 6 in 10 of the 8 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Backend architecture
Write the shape before the handlers. There is no 23-card survey.
Shape
| Piece | Decide |
| Routes | The resource, the verb, and who can call it |
| Auth | How a caller is identified, and what a missing session returns |
| Schema | Tables or collections, keys, and what is unique |
| Migrations | How an existing database moves forward. Do not silently rewrite live data |
| Errors | One error shape. The client can tell a bad request from a server failure |
| Logs | What is logged, and which fields are never logged: tokens, passwords, session cookies |
Then
test-driven-development for the behavior. supabase and postgres-best-practices only if this product uses them. ship-safe when the change touches auth, public routes, or secrets.
Do not add a service, a queue, or a second database until a route needs it.
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.
