reference-pack skillA
reference-pack is agent-read markdown (skill) from garrytan/gbrain: Reference skill demonstrating the 10/10 skillpack contract. Adds a "what does this skillpack do" answer to the user's agent..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# reference-pack This is the canonical reference for a third-party gbrain skillpack. Read its tree once and you know how to author one. ## What this skill does When the user asks how third-party gbrain skillpacks work, this skill points them at the four artifacts every pack ships: - `skillpack.json` — declares pack metadata + which artifacts the doctor scores (skills, unit_tests, e2e_tests, llm_evals, routing_evals, runbooks, changelog). - `skills/<name>/SKILL.md` — frontmatter (name, description, mutating, triggers) plus markdown body. Agents route on `triggers:`; the body is the in-context instruction set. - `runbooks/bootstrap.md` — agent-readable post-scaffold steps. gbrain DISPLAYS this after `scaffold` lands; the agent walks per-step at its own discretion. No auto-executor (codex T1 supply-chain hardening). - `CHANGELOG.md` — Keep-a-Changelog shape. The doctor's `changelog_ present_and_current` dimension fails if there's no `## [<version>]` entry matching the manifest's `version`. ## What the doctor scores Ten binary dimensions, split into: **Core (5; must all pass to publish at any tier):** 1. `manifest_valid` — schema-validates skillpack.json …
