Get traceability matrix

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

The annotations already declare readOnlyHint=true, so the description doesn't need to restate that. The description adds some context about the report's content but does not disclose details like pagination behavior or response format. This is a slight improvement over no additional behavior info, matching the baseline for read-only tools with annotations.

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 sentences, with the action and resource front-loaded. Every word earns its place, efficiently conveying purpose and context without unnecessary filler.

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 read-only retrieval tool with good schema coverage and no output schema, this description is complete enough. It explains the purpose and the content of the returned matrix, and the 'coverage audits' hint is useful. While it doesn't detail pagination or filtering, those are well covered by the schema, so no major gaps remain.

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?

All parameters are already described in the JSON schema with 100% coverage. The description adds no additional parameter-level semantics, so it provides no value beyond the schema. Baseline 3 is appropriate when schema is the primary source of parameter information.

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 ('Retrieve') and resource ('requirement traceability matrix report'), and elaborates on the content ('requirements with their covering test cases'). This distinguishes it from sibling tools that are named differently (e.g., 'get_requirement_coverage' might focus on individual coverage rather than the entire matrix report).

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 provides a clear usage context: 'Useful for coverage audits.' This tells the agent when to use the tool, though it does not explicitly mention alternatives or exclusions. That is sufficient for a basic use case.

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