What it does

Tool Catalog is an agent 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.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `README.md` and `host-contract.json`).

The repository describes itself as: Claude Code skills for architecture, real estate, and workplace strategy. Type /skill-name and go. The licence is MIT.

When your agent uses it

  • How do I use Arch Studio
  • A capability directory

Example prompts

  • “/tool-catalog”

Requirements

  • Pre-approved tools (allowed-tools): Read

What it can do on your machine

Read from SKILL.md and the folder at commit 657bfd5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tool Catalog loads about 803 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~803

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

tool-catalog

Before acting, read the host contract and this component’s declaration (skill:tool-catalog). Load only applicable modes from the shared catalog; declarations do not grant access or permission. Use the actual host’s delivery route.

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 and generated practice discovery. 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.

For Arch Studio onboarding or troubleshooting beyond a directory answer, the Norma support procedure owns that support outcome; its presence does not imply an active email service or shared chat history.

Norma coordinates work; direct skill invocation remains valid. A substantial task may benefit from a workplan and approved team; a quick task needs no extra gate. Records require accessible selected workspace files. For workflows explicitly declared harness-native, the host follows the owner's complete procedure using its actual capabilities; no Arch Studio runner or executable installation is required. Report the selected workflow's actual declaration and any unresolved capability gap; do not infer catalog-wide execution support. A hosted connection or a displayed skill alone proves neither file access nor completed work. Optional agent profiles are available only when actual host registration/delegation is observed, including the Norma worker after context and approval are resolved.

This directory procedure has no registered operation IDs or record effects. Read its maintained metadata through the actual delivery channel and use the completion contract. Do not invent dispatch operations, run an installer, activate another workflow or perform setup merely to answer a help question. Report unknown host capabilities as unknown.

For external-source directories use the source catalog with geography/topic filtering. Return matching original links, distinguish code sources from related datasets, and state available-manifest coverage. No content retrieval, studio setup or permission is required for listing. Missing LA routes do not substitute NYC. See moments for state facts and the source contract for interpretation boundaries.
