get_milestone

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

The description 'Fetch a milestone' is consistent with the annotations (readOnlyHint=true, destructiveHint=false, idempotentHint=true). It adds no behavioral context beyond what annotations already provide, such as error behavior or return format. However, the annotations cover the safety profile, so this is adequate.

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, concise sentence with no filler or redundant information. It is appropriately front-loaded and every word earns its place.

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 two-parameter read operation with rich annotations and complete schema descriptions, the description is adequate. It does not detail the return shape, but the tool name and context imply a milestone object. No output schema exists, but the minimal description still fills its purpose for a straightforward getter.

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 100%, with both project_id and milestone_id described as 'the id of the project' and 'the id of the milestone'. The description 'Fetch a milestone' does not add any additional parameter semantics beyond what the schema already provides. Baseline applies.

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 'Fetch a milestone' clearly uses a specific verb and resource, indicating a single milestone retrieval. It does not explicitly distinguish from list_milestones, but 'a milestone' implies a single resource. Overall, purpose is clear and unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives like list_milestones. There is no mention of when not to use it, prerequisites, or context. The description is purely declarative and offers no usage direction.

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