Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions authentication requirements and domain focus, but does not disclose rate limits, response format, or error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat verbose and mixes languages (English and Japanese), which may be acceptable for a multi-language tool but could be more concise. The key points are present but front-loaded with less critical details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool is a chat interface with no output schema, the description covers essential aspects: what topics it handles, authentication, pricing, and parameter usage. It is largely complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning beyond the schema by specifying that 'message' is required and 'history' is optional with a specific structure (array of {role, content}). This is helpful for invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool is an AI chat about specific domains (architecture, BIM, code, MU) and is distinct from the sibling tools which are more action-oriented (e.g., create_house, delete_zoning_rule).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear usage context: requires API key, has free initial credits, and accepts an optional history parameter. However, it does not explicitly state when not to use it or suggest alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools have distinct purposes, but some potential overlap exists (e.g., get_site_context and get_houki_rules both provide site conditions, and set_site_context vs. upsert_zoning_rule could be confused). Overall, descriptions help disambiguate.
Tools predominantly use a verb_noun pattern (e.g., create_house, update_house, set_visibility). A few outliers like houki_check and whoami break the pattern, but naming is mostly consistent.
29 tools is heavy but covers a broad domain (house design, construction, catalog, contractors, admin). Some tools are niche (e.g., list_incomplete_addresses, set_forkable), but each serves a clear purpose. Could be streamlined.
Core operations for house lifecycle (create, read, update, check) are present. Lacks explicit delete/archive for houses (only set_visibility), and no tool to update site context directly (only set via set_site_context). Minor gaps but domain is well-covered.
