data-modeling
Skill0 starsChanged 14 days agoNo licenceView on GitHub
Design application database schemas that can be trusted with money and history for decades — money as exact integers, ledgers instead of mutable balances, explicit state machines, immutable catalogs, point-in-time snapshots, tenant-scoped rows, and additive evolution. Use when creating or altering tables, writing migrations, modeling money, balances, payments, subscriptions, invoices, orders, or any record with a lifecycle, designing multi-tenant schemas, or reviewing a data model or migration. Triggers on tasks involving schema design, data models, ERDs, CREATE TABLE / ALTER TABLE, ledgers, audit trails, soft deletes, or status columns.

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
Show its rules and text
We split this skill into the rules it gives an agent
16 rules. 0 are common, 11 are distinctive, and 5 are very specific to this project.
0
Common
Most of the 15 edited versions we read keep these.
11
Distinctive
This author's own choices. Worth a look.
5
Very specific
Tied to their project's names, files or tools. Probably skip.
No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.
“Common” is measured: kept by at least 6 in 10 of the 15 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.

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.
