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

Annotations already declare this as a safe, read-only, idempotent, non-destructive operation, but the description adds substantial behavioral context beyond that: machine-only entries, reuse of author text, reviewed navigation questions, preservation of original wording and attribution, optional next_steps with a guided-tour invitation, and no booking or sending. This is rich disclosure for a read tool.

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 front-loaded with the main action and stays reasonably tight across four sentences. Some phrases, such as 'reviewed navigation questions bound to complete current passages', are dense, but each sentence contributes relevant context.

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 read tool with annotations and an output schema, the description is complete enough: it covers purpose, prerequisite ID source, behavioral nuances, attribution, next_steps, and the no-booking boundary. Nothing essential for correct invocation is missing.

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 schema has 0% description coverage and only one parameter, so the description must carry the semantic load. It does so by explicitly tying place_id to a value returned by search_knowledge, which is the key information an agent needs. It does not add format details, but those are largely covered by the schema's type and length constraints.

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 uses a specific verb, 'Read', and names concrete resources: published introduction, author passages, questions, and related topics for a place ID. It distinguishes itself from search_knowledge by requiring an ID returned by that tool, though it does not explicitly distinguish itself from get_answer, get_questions, or get_services.

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 gives a clear prerequisite: the place_id must come from search_knowledge. It also states 'No booking or sending', which sets a usage boundary. It does not, however, explicitly say when to use this instead of sibling tools like get_questions or get_answer.

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