app_categories__get

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

Annotations already indicate readOnlyHint, idempotentHint, and destructiveHint=false. The description simply says 'Read' and provides the HTTP method, adding no behavioral context beyond annotations. No mention of response format, error handling, or relationship-related 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 a single, compact sentence that immediately conveys the primary action and target, followed by the endpoint. No filler or redundant words. It is appropriately sized for a simple getter.

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 get-by-ID operation with strong annotations and complete schema descriptions, the description is adequate. It makes the core operation clear, though it could mention that related data can be included via the include parameter. The lack of an output schema is mitigated by the simplicity of the resource.

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?

Input schema covers all three parameters with descriptions, achieving 100% schema_description_coverage. The tool description itself adds no parameter details beyond mentioning the ID. Baseline of 3 applies because the schema carries the parameter documentation burden.

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's function with a specific verb and resource: 'Read one app category by ID.' This distinguishes it from sibling list and related-resource endpoints. The REST endpoint [GET /v1/appCategories/{id}] reinforces the single-resource 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 implies usage for fetching a single category by ID, but does not explicitly mention when to use alternatives like list, parent, or subcategories. Context suggests the appropriate use case, but no exclusions or alternative tool references are provided.

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