Clear job and output
The source explains when to use the Skill, what to bring, and what a useful result looks like.
This is not an automated list sorted by stars. Inclusion requires a clear job, traceable source, useful documentation, and explainable risk boundaries.
Selection method
There is no universal winner across jobs. Selections are reviewed for usefulness, evidence, maintenance, risk, and alternative value.
The source explains when to use the Skill, what to bring, and what a useful result looks like.
Repository popularity is contextual. Documentation, source depth, maintenance, and test evidence carry more weight.
Thin source files, unclear identity, abandoned projects, or unbounded external actions are excluded.

End-to-end discipline for turning any large data source (audio libraries, email takeouts, document corpora, chat exports, API dumps) into brain pages at scale.

State is tracked in a durable JSON manifest (see MANIFEST-PATTERN.md) so any crash, session boundary, or subagent fan-out resumes from ground truth instead of memory.
