update_milestone

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

No annotations are provided, so the description must cover behavioral traits. It mentions mutation ('updates') and verbosity options, but does not discuss error handling, required permissions, partial vs. overwrite behavior, or what happens if the milestone does not exist. The output schema exists but is not described.

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 concise with only two sentences. It provides essential information without redundancy, but could be better structured by grouping related details.

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 complexity of a mutation tool with 4 parameters (1 required, 3 optional) and an output schema, the description is incomplete. It lacks detail on verbosity values, error scenarios, and how kwargs are used. The output schema exists but the description does not leverage it.

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. It explains verbosity options and session_id default behavior, but 'milestone_id' and 'kwargs' are not described. 'kwargs' is particularly vague and leaves ambiguity about what can be updated.

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 'Updates details of an existing milestone,' which is a specific verb+resource combination. It distinguishes from sibling tools like create_milestone, get_milestone, and delete_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 implies usage for updating a milestone but does not explicitly state when to use this tool versus alternatives or when not to use it. No alternatives or exclusions are mentioned.

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