skill_installerlisted

# skill_installer Install a `.skill` bundle into `~/.ciel/skills/`. ## Operations - `install(path_or_bytes)` — unzip → validate schema → checksum → register. - `install.dry_run(path)` — what would happen without applying. - `install.uninstall(id)` — remove from registry; move to `~/.ciel/.attic/`. - `install.list()` — installed skills with versions. ## I/O Contract ```yaml io_contract: input: { op, path_or_id, "dry_run?" } output: { result, changes } idempotent: for_same_version side_effects: [fs, state_mutation] ``` ## Safety Installs always flow through `council/invocation_scopes/SKILL_INTEGRATION.md`. Bypass is forbidden by Constitution.
