Declarative skill deck governance. `deck link` reconciles the working set to match skill-deck.toml — deny-by-default removes undeclared skills. DEFAULT patterns: PHASE SWITCH via separate deck files (deck link --deck phase<N>.toml), SEED bootstrap (minimal deck → agent self-expands via deck add + curator discovery). Always restores parent deck. Zero state pollution between phases. INNATE FIRST: after compaction, session reload, or skill refresh — read every innate skill's full SKILL.md before…
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
# lythoskill-deck: Declarative Skill Deck Governance > What matters is not how many skills you have, but which ones the agent sees at the same time. > **Invocation.** Body text uses the `deck <cmd>` shorthand. Run commands as > `bunx @lythos/skill-deck@0.21.0 <cmd>` (no install), or > `lythoskill-deck <cmd>` if installed globally. The bare `deck` name is an > in-repo alias convention in the lythoskill monorepo only — NOT a registered > bin (the npm package registers `lythoskill-deck`). Same mapping: `arena` → > `@lythos/skill-arena`, `curator` → `@lythos/skill-curator`, `cortex` → > `@lythos/project-cortex`. > Want the shorthand? Register it yourself — e.g. > `alias deck='bunx @lythos/skill-deck@latest'` in your shell config. > Optional, your machine, your choice. ## Core Model `skill-deck.toml` declares desired state. `deck link` makes the working set (default `.claude/skills/`) match — creates symlinks for declared skills, removes everything else. Deny-by-default: undeclared skills do not exist in the agent's view. ``` Cold Pool (~/.agents/skill-repos/) → deck add → skill-deck.toml → deck link → .claude/skills/ …

How to install
mdr add lythos-labs/lythoskill/lythoskill-deck@sha256:612721eb9bc63c44The line at the top of this page pins the label v0.21.0, 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.
