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.
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
# 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. …

How to install
mdr add alpacalabsllc/skills-for-architects/tool-catalog@sha256:99f3717f538545f0The line at the top of this page pins the label git:20260920.ef0a19e, 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.
