update_milestone_tool

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

With no annotations, the description carried the full burden of behavioral disclosure, but only says 'Update an existing milestone.' It omits that state transitions (e.g., close/activate via state_event) are possible, and gives no indication of idempotency, side effects, or required permissions. For a mutation tool with 7 parameters, this is thin.

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 four words with no fluff and is instantly scannable. It is as concise as possible while remaining grammatical, earning a top score for efficiency.

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 tool with 7 parameters, 2 required, and no annotations, this description is under-specified. It doesn't mention that only provided fields are updated, what state_event does, or what the response contains. While an output schema exists, the description fails to add value for an API with non-trivial update semantics.

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%, so the schema already documents all parameters, meeting the baseline of 3. The description adds nothing beyond the schema, but no additional clarification is strictly required. It's neutral, not additive.

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 the verb 'Update' and the resource 'an existing milestone' clearly. However, it largely restates the tool name and gives no details about what fields can be updated or side effects. It doesn't distinguish from sibling update tools beyond the subject.

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 on when to use this tool versus alternatives like create_milestone_tool or list_milestones_tool, nor mention of partial update semantics. There is no context that would help an agent decide when this is the right choice.

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