Get Milestone

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

Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is clear. However, the description adds no further behavioral context (e.g., what happens if the milestone does not exist, authentication requirements, or rate limits).

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 one succinct sentence with no superfluous words. It is front-loaded with the core action. However, it could be slightly more informative without losing 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?

Given the number of sibling tools and the lack of an output schema, the description omits important context: what the tool returns (e.g., milestone object fields), how to scope the query with project_id, and how it differs from more specific milestone retrieval tools. This leaves the agent with 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%, and the description does not explain the parameters (project_id, milestone_id) beyond their names. While 'milestone_id' is self-explanatory, the optional 'project_id' is not clarified, leaving ambiguity about its necessity or relationship to the milestone.

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 'Get a milestone by ID' clearly states the verb (Get), resource (milestone), and method (by ID). It is specific and effectively distinguishes this tool from sibling tools like gitlab_create_milestone, gitlab_delete_milestone, and others.

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 no guidance on when to use this tool vs alternatives such as gitlab_list_milestones, gitlab_get_milestone_issues, or other milestone retrieval tools. No context on prerequisites or typical use cases is given.

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