Create Milestone

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

The description offers no behavioral details beyond what annotations already provide (readOnlyHint=false, destructiveHint=false). It does not disclose side effects, required permissions, or handling of duplicate milestones. The description adds no extra context to the annotation set.

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 only one sentence, so it is very concise with no fluff. However, it is under-specified; it repeats the title almost verbatim and provides no additional structure or information that would help an agent.

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?

For a create tool with four required parameters and no output schema, the description is incomplete. It does not explain return values, side effects, or how this tool fits among many siblings. The lack of behavioral and parameter information makes it difficult to invoke 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?

The description does not explain any of the four parameters. The input schema covers only two parameters with descriptions (estimated_start, estimated_finish), leaving name and project undocumented. With 50% schema coverage, the description should compensate but does not.

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 states a clear verb+resource ('Create a new milestone'), which is specific enough to identify the tool's core function. However, it does not add any contextual scope (e.g., that it operates within a project) or differentiate itself from sibling create tools beyond naming the resource.

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?

There is no guidance on when to use this tool versus alternatives. It simply says 'Create a new milestone' without mentioning prerequisites, exclusions, or when another tool (like milestone_update or milestone_delete) would be more appropriate.

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