milestone_list

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

With no annotations, the description carries the burden of behavioral disclosure. The verb 'List' implies a read-only operation, and the filter values give some sense of behavior, but the description does not explicitly state side effects, authorization needs, or pagination behavior. It is minimally adequate for a listing tool.

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 short and front-loaded with the main action, followed by a compact list of parameter values. Every sentence earns its place, and there is no redundant or vague filler.

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 simple tool with two optional parameters and an output schema, the description covers the essential invocation details, including allowed values. It lacks explicit usage guidance and a clear statement of non-mutation, but these gaps are minor for a straightforward listing operation.

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 schema provides only property names with string/null types and no enums, so the description fully compensates by enumerating valid values for both parameters: kind as 'release' or 'stream' and state as 'open'/'closing'/'shipped'/'archived'. This adds essential meaning beyond the schema.

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 specific verb and resource: 'List milestones with optional filters.' This clearly identifies what the tool does and distinguishes it from sibling milestone tools like milestone_create or milestone_status. The purpose is immediately understandable.

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 such as milestone_audit_query or milestone_status. It only describes what the tool does, not the conditions that would make it the right choice among the many sibling tools.

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