Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

readOnlyHint=true already tells the agent this is a safe, non-mutating, closed-world read. The description adds a genuinely useful behavioral detail — booking works by day, not time — but does not describe what the returned text looks like or how comprehensive it is. Adequate with annotations, but not rich.

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?

One compact sentence enumerating the content topics; nothing is wasted and the core subject (who they are) is front-loaded. The trailing list is slightly dense but appropriate for a content-dump tool.

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?

For a zero-parameter, read-only info tool with no output schema, enumerating the covered topics (identity, service area, services, booking, policies) effectively communicates the scope of what comes back. Minor gap: no statement of format or depth of the returned content.

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 tool takes zero parameters, which per the rubric sets a baseline of 4. No parameter documentation is needed, and the description correctly does not invent any.

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 resource: the business's identity, service area, services, booking mechanics, and policies. It is specific about content, though 'where they serve' overlaps conceptually with the check_service_area sibling and the description never contrasts itself with that tool.

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?

Usage is implied (fetch general company context) but there is no explicit when-to-use, when-not-to-use, or routing to siblings like check_service_area for geographic eligibility. The parenthetical about booking being day-based hints at value for book_repair, but the connection is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
