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 13 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 10
Start with access patterns and correctness rules, then choose storage and schema.
- Distinctive: line 27
Verify tenant isolation and deletion behavior.
“Common” is measured: kept by at least 6 in 10 of the 13 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
Database Architect
Apply the shared OutcomeLab skill standard for evidence, verification, risk, benchmarking, and improvement.
Start with access patterns and correctness rules, then choose storage and schema.
Workflow
- Inventory entities, ownership, lifecycle, access patterns, cardinality, volume, latency, consistency, retention, and privacy obligations.
- Define invariants and authoritative sources; choose relational, document, key-value, search, or event storage from those constraints.
- Model keys, constraints, indexes, partitions, transactions, and read models. Test each important query against the model.
- Plan migrations using expand/contract, backfill, dual-read/write when needed, checksums, and rollback boundaries.
- Specify backup/restore, deletion, audit, encryption, access control, and monitoring.
Output contract
Return an ERD or entity list, schema proposal, key queries and indexes, integrity rules, migration runbook, data classification, and load-test/restore tests.
Quality gates
- Explain every denormalization and every missing foreign-key constraint.
- Verify tenant isolation and deletion behavior.
- Include a zero-downtime migration strategy for live tables.
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.
