tool-catalog skillA
tool-catalog is agent-read markdown (skill) from alpacalabsllc/skills-for-architects: Show Arch Studio help, available skills, agents and host-specific commands. Use for help, how do I use Arch Studio, what is Norma, or a capability directory..
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
# tool-catalog Before acting, read the [host contract](../../docs/host-harness-contract.md) and this component’s [declaration](host-contract.json) (`skill:tool-catalog`). Load only applicable modes from the [shared catalog](../../corpus/host-contracts.json); declarations do not grant access or permission. Use the actual host’s [delivery route](../../docs/host-adapters.md). Provide read-only help for “help”, “how do I use Arch Studio”, “what is Norma”, available skills, agents and commands. Start with the actual delivery channel and known workspace state when relevant; do not run setup just to answer help. Read the current [component registry](../../corpus/components.json) and [generated practice discovery](../../docs/practice-clusters.md). Select the requested scope and show names, short purposes and actual host-discovered entry points. A directory is generated from maintained metadata, not a second static skill list. For a broad help request give two or three useful next actions; a focused capability question gets a focused answer. …
