create_project_milestone

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

The description discloses the important default behavior (dry_run=true) and implies it is a write operation, consistent with readOnlyHint=false. It adds value beyond annotations by explaining the preview mode.

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?

Two succinct sentences with no wasted words. The first sentence states purpose; the second highlights a critical behavioral detail.

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 description covers creation purpose and dry_run behavior but lacks information on return value or success response. With no output schema, it would benefit from mentioning what the tool returns after creation.

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 coverage is 100% with clear parameter descriptions; the description adds no new meaning beyond stating the dry_run default, which is already in the schema. Adequate but no added value.

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 'milestone on a project', which is specific and distinguishes it from sibling tools like 'create_milestone' or 'close_milestone'.

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., 'create_milestone' for group milestones, 'close_project_milestone'). The mention of dry_run default is a usage note but not about tool selection.

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