trailhead chart cluster: the verbs that give a map its start or bring outside work into it. Chart a new map from a loose idea (new), adopt an existing codebase into a map (adopt), open a ticket of any type on the fly (ticket), triage issues opened by others into the map (inbox), and run a standalone grilling session (grill). A cohesion cluster of the trailhead skill split, loading the shared `_shared/` core; reached through the `/trailhead:<verb>` command wrappers and the bare `/trailhead`…
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-chart` is the **chart cluster** of the trailhead skill: the verbs that give a map its start or bring outside work into it. `new` charts a new map from a loose idea; `adopt` maps an existing codebase into a map; `ticket` opens a ticket of any type on the fly; `inbox` triages issues opened by others; `grill` runs a standalone grilling session. Everything lives on the GitHub Issues; the repo holds code only. ## Load first, in order Before doing anything, load `<skill base>/../_shared/load-first.md` and follow it: the shared-core load contract (the six core files, in order, then the effective config). `<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 the 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). The same rule covers every later `../_shared/...` or `references/...` path in this skill: resolve it against the base directory to an absolute… …

How to install
mdr add torvaldz/trailhead/trailhead-chart@sha256:d29d6c8e703affabThe line at the top of this page pins the label git:20261104.db0ddd4, 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.
