create_milestone

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

The description adds no behavioral context beyond what annotations already convey. It fails to mention side effects, return values, permissions, or any constraints, even though annotations present a baseline. With readOnlyHint=false and destructiveHint=false, the description's 'Create' is consistent, but it contributes nothing extra.

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 extremely short, but this is under-specification, not concise writing. A single sentence that simply restates the tool name does not earn its place and provides no useful information.

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 has five parameters, no output schema, and no behavioral disclosure. A create operation with this complexity requires explanation of return values, dependencies, and potential edge cases, all of which are missing. The description is wholly inadequate for an agent to use the tool correctly.

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% (every parameter has a description), so the baseline score is 3. The description itself adds no parameter-related insights, but the schema already documents all fields adequately, including required and optional properties.

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 'Create milestone' is a near-verbatim restatement of the tool name, providing no additional specificity about the resource or context. It does not distinguish the tool from sibling operations like update_milestone or list_milestones, and offers no insight into what a 'milestone' is in this domain.

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. It does not mention prerequisites, relationships, or situations where a different tool would be more appropriate, leaving the agent to infer applicability solely from the name.

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