trailhead-capture is the capture cluster of the trailhead skill: the zero-friction captures that record work without breaking flow. bug captures a bug ticket; todo captures a small build ticket you will do now; idea captures a fog idea; seed captures a trigger-gated seed; note captures a verbatim note. Everything lives on the GitHub Issues; the repo holds code only.
Load first, in order
Before doing anything, read ../_shared/load-first.md and follow it: the shared-core load contract (the six core files, in order, then the effective config). _shared/ is a sibling of this cluster's own directory (at ../_shared/), never a child of it; its absence from a listing of the cluster dir is expected, not a missing core.
A capture writes at most one issue; no isolation workspace is set up.
Routing: verb to engine
The first word of the arguments is the verb (bug, todo, idea, seed, or note); the rest is the text (or --of <ticket> <text> for bug).
bug/todo/idea/seed/notetoreferences/capture.md: the full per-verb protocol and the note/idea/seed/todo spectrum. Read that file and follow it.
The cross-cluster situational references and technique bodies these captures call live in _shared/; this cluster names each by its ../_shared/... path where it needs one.
