get_milestone

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

No annotations are provided, so the description carries the full burden. It states 'Get a specific milestone by ID', implying a read-only operation, but doesn't disclose behavioral traits such as authentication needs, error handling (e.g., what happens if the ID is invalid), rate limits, or response format. This leaves significant gaps for a tool with no structured safety hints.

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, efficient sentence: 'Get a specific milestone by ID'. It's front-loaded with the core action and resource, with zero wasted words, making it easy to parse quickly for an AI agent.

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 tool's simplicity (1 parameter, no output schema, no annotations), the description is minimal but incomplete. It lacks context on usage, behavioral details, or output expectations, which are crucial for an agent to invoke it correctly without annotations or output schema to fill in 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?

The input schema has 100% description coverage, with 'milestone_id' documented as 'Milestone ID'. The description adds no additional meaning beyond this, as it only repeats 'by ID' without explaining ID format, sources, or constraints. With high schema coverage, the baseline score of 3 is appropriate, as the schema does the heavy lifting.

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 specific milestone by ID' clearly states the action (get) and resource (milestone), but it's vague about what 'get' entails (e.g., retrieve details vs. fetch metadata) and doesn't distinguish it from sibling tools like 'get_milestones' (plural) or 'get_case', which suggests a basic but non-specific purpose.

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. For example, it doesn't mention if this is for retrieving a single milestone's details after listing with 'get_milestones' or how it differs from other 'get_' tools like 'get_case' or 'get_plan', leaving the agent without context for selection.

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