Design and write PostgreSQL databases, tables, columns and migrations in this organisation's house style — lowercase unseparated identifiers, `id` serial/bigserial primary keys, `organizationid` tenancy with a hand-named FK, the five-column audit block, soft delete via `isdeleted smallint`, booleans as `int2` 0/1, varchar+CHECK instead of Postgres ENUMs, no triggers and no ON DELETE cascades, partial indexes on `isdeleted = 0`, and hand-applied idempotent migration files with a header block and a commented rollback. Detects an existing schema's real conventions first, generates the DDL from the matching table shape (master / document / lineitem / map / log), then lints the result mechanically. Use whenever someone asks to create a database, add or alter a table or column, design a schema, write a migration, add an index or constraint, or review DDL for a Node/Express + PostgreSQL project.

    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

13 rules. 0 are common, 5 are distinctive, and 8 are very specific to this project.

  • 0

    Common

    Most of the 3 edited versions we read keep these.

  • 5

    Distinctive

    This author's own choices. Worth a look.

  • 8

    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 3 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.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

What did you use it for? e.g. Reviewing pull requests in a Rails app

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.
