Internal to the capstone suite - carries the shared rules (references/) and scripts every capstone subcommand reads; it exists so npx-skills installs ship them alongside the command skills. Not meant to be invoked directly; when invoked anyway, run references/../scripts/help.sh and output its stdout verbatim.
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
# Capstone: core (internal) This folder is the capstone suite's shared brain: `references/` (core rules, protocols, craft files) and `scripts/` (help, config initializer, lint, and `map-check.sh`, the script half of `map check` that the CI gate runs). Every other capstone skill resolves it as `../core/` from its own base directory, so install the whole suite; a lone capstone skill without `core` cannot run. Invoked directly, print the usage: run `scripts/help.sh` via bash from this skill's base directory and output its stdout verbatim; nothing else.
Read the whole file at its exact version.
How to install
mdr add gentbajko/capstone/core@sha256:68c2b5e146ee3cc8The line at the top of this page pins the label git:20260906.de9e720, 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.
