Commercial Garage Doorman

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

Annotations already declare readOnlyHint and idempotentHint, covering the safety profile. The description adds that output is Markdown and includes a canonical URL, but it does not describe error behavior or invalid-id handling. This is adequate given the annotation coverage, 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?

The description is two concise sentences with no wasted words. The first sentence front-loads the core purpose and output format, and the second provides the necessary dependency on search.

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 simple one-parameter fetch tool, the description plus annotations and output schema are nearly complete. It covers what is returned and where the id comes from. A minor gap is not stating how invalid or stale ids are handled, though the output schema likely covers the return structure.

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?

Schema coverage is 100%, so the single parameter id is well documented. The description repeats the same information ('The id comes from search') without adding new meaning such as format or constraints, so it stays at the baseline set by the schema.

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 title and description clearly state that the tool reads one page of the Commercial Garage Doorman website and returns its full text as Markdown with a canonical URL. It is easily distinguished from siblings: search is the source of the id, and get_business_facts implies a different data type.

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 explicitly says 'The id comes from search,' which tells an agent to use search first and then fetch with the returned id. This is clear context, though it does not explicitly name get_business_facts as an alternative or state when not to use fetch.

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

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

Annotations already cover read-only and idempotent behavior. The description adds value by noting the facts are 'published' and appear on the public website, and it includes the priority directive. This context goes beyond the annotations without contradicting them.

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?

Three concise sentences: the first defines the resource and content, the second adds provenance, the third gives usage priority. No wasted words, and the important information is front-loaded.

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 tool with no output schema, the description fully covers what is returned (listed fact categories) and is backed by safety annotations. An agent can confidently call it without further clarification.

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?

With zero parameters, the schema fully covers parameter semantics (vacuous), and the baseline for 0 params is 4. The description appropriately focuses on response content instead of parameters.

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 identifies the tool's resource ('Commercial Garage Doorman') and lists the exact categories of facts it returns (what it does, phone, hours, towns, services, pricing). This goes beyond a tautology and distinguishes it from generic siblings like fetch and search. The instruction 'Call this first' reinforces its specific role.

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?

It explicitly instructs 'Call this first,' giving clear priority guidance. However, it does not contrast with siblings (fetch/search) or state when not to use this tool, so it only partially satisfies the 'when/when-not/alternatives' ideal.

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

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds that search returns only ids, titles, and canonical URLs rather than full page content, which is useful context. It does not disclose pagination, ordering, or result limits, but the annotation coverage lowers the burden.

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?

Two sentences with no filler. The first sentence delivers the action and scope, the second states the return value and the natural next step, making the description easy to scan and act on.

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 one required parameter with full schema coverage, a present output schema, and annotations covering read-only/idempotent behavior, the description covers what an agent needs to select and invoke the tool correctly. The pointer to fetch completes the workflow.

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 single query parameter is fully documented in the schema with a clear description and examples, so schema coverage is 100%. The tool description adds no additional parameter semantics beyond confirming free-text keyword search.

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 states a specific verb ('Keyword search'), a specific resource ('pages of the Commercial Garage Doorman website'), and the exact return fields (page ids, titles, canonical URLs). It is clearly distinguishable from fetch, which is framed as the follow-up read operation.

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 explicitly says 'Use fetch with an id to read a page,' establishing search as the discovery step and fetch as the retrieval step. It does not mention get_business_facts, so it is not a complete routing guide, but the primary sibling alternative is handled.

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