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

No annotations are provided, so the description must fully disclose behavioral traits. It describes the relationship type (MAPS_TO) and gives an example, but lacks information on pagination, potential large response size, error conditions (e.g., control not found), and whether the operation is read-only. The basic function is conveyed, but important behavioral details are missing.

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 core description is two sentences and an example, which is concise. However, the 'Responses' section is poorly formatted and adds noise ('200: Successful Response (Success Response)') without providing useful information. This detracts from the overall conciseness.

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?

The tool is simple (one parameter, no output schema), and the description explains the mapping concept and use case. However, it lacks explicit parameter documentation, behavioral details (pagination, errors), and does not leverage the sibling list to differentiate. It is minimally complete but has clear gaps.

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 description coverage is 0%, so the description must compensate. It implies that 'code' is the identifier of the control (e.g., from the example 'AC-1'), but it does not explicitly define the parameter's format, expected values, or provide an example. The description adds some meaning beyond the schema but is not fully explicit.

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 it 'Get cross-framework mappings for a control' and explains it returns controls mapped via MAPS_TO relationships. However, it does not differentiate from the sibling tool 'agent_cross_framework_map', which likely has a similar purpose. The example (NIST 800-53 equivalents of ISO 27001) adds concreteness.

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 says 'use it to find equivalent controls across different compliance frameworks' which implies the context of use. However, it does not specify when not to use it or mention alternatives, particularly the sibling 'agent_cross_framework_map'. The usage context is implied but not explicit.

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