create_milestone

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

With no annotations, the description carries full burden. It indicates a write operation ('create') but does not disclose side effects, authentication needs, idempotency, or return value behavior. The date format hint is the only behavioral detail.

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 very concise: one sentence plus a format note. It is front-loaded and wastes no words. However, it could include a bit more context without becoming verbose.

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 5 parameters, an output schema, and sibling tools, the description is woefully incomplete. It does not leverage output schema or sibling relationships to provide context (e.g., how to obtain project_id). The tool's creation nature demands more setup guidance.

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%, so the description must add meaning. Only 'due_date' gets format clarification (YYYY-MM-DD). No information is provided for 'platform', 'project_id', 'title', or 'description' beyond their schema titles.

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 'Create a new milestone in a project', specifying the action ('create') and resource ('milestone') with project context. This distinguishes it from sibling tools like update_milestone, close_milestone, and list_milestones.

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 on when to use this tool versus alternatives (e.g., update_milestone). Prerequisites like having a valid platform and project_id are not mentioned. The description lacks any when-to-use or when-not-to-use advice.

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