create_milestones

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

No annotations are provided, so the description carries full burden for behavioral traits. It explains the return format (unified response with items, counts, per-item errors), which is helpful, but fails to disclose side effects, permissions, idempotency, or error handling beyond per-item errors. The description is adequate but not comprehensive.

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, front-loaded with the core purpose, and no superfluous words. Every sentence adds value (purpose and return format). This is an example of efficient, well-structured documentation.

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 no output schema, the description adequately explains the return format. Parameter details are fully covered in the schema. However, the tool is a creation operation and lacks context on prerequisites, required permissions, or idempotency. The sibling list includes many creation tools but no differentiation is provided. Overall, reasonably complete for a straightforward creation tool but with minor 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 covers 100% of parameters with descriptions, so the schema does most of the work. The description adds no additional meaning for parameters, only mentioning the return structure. Baseline 3 is appropriate given high schema coverage.

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 verb 'Create' and the resource 'milestones', and mentions the array-based interface supporting both single-item and batch calls. However, it does not explicitly distinguish this tool from sibling tools like 'create_boards' or 'create_projects', leaving the differentiation implicit.

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 versus alternatives (e.g., other creation tools in the sibling list). It only mentions that single and batch calls use the same interface, but does not specify prerequisites, constraints, or exclusion criteria.

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