list_milestones

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It only states the basic operation and return type, without mentioning pagination, sorting, filtering behavior, or potential performance implications. This is a significant gap for a list operation.

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 and well-structured with Args and Returns sections. Each sentence contributes useful information, but it could be slightly more polished by avoiding redundancy with the schema (e.g., repeating parameter names). Overall, it is efficient.

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 list tool with an output schema, the description covers the essential purpose and Parameters. However, it omits usage guidelines and behavioral details (e.g., whether params support pagination or sorting). Given the presence of an output schema, return values are less critical, but the lack of guidance on when to use this tool and its limitations makes it only minimally complete.

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 compensate. It does add meaning by specifying 'project_id: UUID of the project' and 'params: Optional query parameters as a dictionary', which provides type and optionality information beyond the bare schema. However, it does not explain what query parameters are supported or how they affect results, leaving room for improvement.

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 the tool's function: 'List all milestones in a project.' It uses a specific verb and resource with a project scope. However, it does not differentiate from sibling list tools such as list_milestone_work_items or list_cycles, so it does not fully meet the 5-level criterion for distinguishing from siblings.

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 retrieve_milestone or list_milestone_work_items. The description only lists parameters and return types, with no mention of 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.
