Start and drive a large project (more than one agent session can hold) as a map of decision tickets on GitHub Issues, resolving one at a time until the way to the destination is clear. Self-contained (zero external-plugin dependencies: trailhead ships its own `trailhead-*` engine agents and needs only an authenticated gh CLI): map-based onboarding and a discuss→plan→execute→verify engine with atomic commits, with everything (map, discussion, plan, verification) living on the Issues. Invoke…
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` charts a large project as a **shared map on GitHub Issues**, then works its **tickets** one at a time until the way to the destination is clear. This skill is the **entry point**: bare `/trailhead` runs **smart entry** (detect the repo state and propose the next move); a verb runs that verb's engine. Everything lives on the 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 path before reading. `_shared/` is a **sibling**… …

How to install
mdr add torvaldz/trailhead/trailhead@sha256:219c1bfe9e128a3fThe line at the top of this page pins the label git:20261014.955d843, 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.
