trailhead capture cluster: the zero-friction captures that record work without breaking flow. Capture a bug ticket (bug), a small build ticket you will do now (todo), a fog idea (idea), a trigger-gated seed (seed), a verbatim note (note). A cohesion cluster of the trailhead skill split, loading the shared `_shared/` core; reached through the `/trailhead:<verb>` command wrappers and the bare `/trailhead` dispatcher. Not auto-invoked: it runs only when one of these verbs is dispatched.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
`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 two files, in order, and nothing else from `_shared/`: `<skill base>/../_shared/capture-core.md` (the compact capture reference: the standing rules, one lookup, the labels and create commands, the ticket body), then `<skill base>/references/capture.md`. `<skill base>` is this skill's **base directory** (Claude Code prints it as `Base directory for this skill:` when the skill loads; on another host, the directory holding this `SKILL.md`): resolve each path to an **absolute path** and open it with the **Read tool** on that absolute path. Never `cd` into a skills directory and never read a relative path from the shell (a `cd` compound followed by a read is denied by the search guard). `_shared/` is a **sibling** of this cluster's own directory (at… …

How to install
mdr add torvaldz/trailhead/trailhead-capture@sha256:deeba318b208fbb6The line at the top of this page pins the label git:20261029.fef01c9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
