create_milestone

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 disclosure. 'Create a new milestone' implies a write/mutation operation but reveals nothing about permissions required, whether creation is idempotent, what happens on success/failure, rate limits, or what the response contains. This is inadequate for a mutation tool with zero annotation coverage.

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 concise—a single three-word phrase—which is appropriately sized for a simple concept. However, it's under-specified rather than efficiently informative. It's front-loaded but lacks substance, so while it's not verbose, it doesn't earn its place with useful content.

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 complexity (a mutation operation with 3 parameters), lack of annotations, 0% schema description coverage, and no output schema, the description is completely inadequate. It doesn't explain what the tool does beyond the name, how to use it, what the parameters mean, or what to expect in return. This leaves critical gaps for an AI agent.

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%, meaning none of the 3 parameters (title, description, dueDate) are documented in the schema. The description provides no information about these parameters—not their purpose, format constraints (e.g., date format for dueDate), or examples. It fails to compensate for the schema's lack of documentation.

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 a new milestone' is a tautology that restates the tool name without adding specificity. It doesn't explain what a milestone is in this context, what resource it creates, or how it differs from similar tools like 'create_sprint' or 'create_project' in the sibling list. The verb 'create' is clear but the object 'milestone' lacks definition.

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 about when to use this tool versus alternatives. The sibling list includes related tools like 'create_sprint', 'create_project', and 'update_milestone', but the description offers no comparison or context about appropriate use cases, prerequisites, or exclusions.

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