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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds a permission caveat ('your account's permissions'), but the MCP/business-workflow approval note is confusing noise for a pure read operation and discloses nothing about result shape or pagination behavior.

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?

It is short and front-loaded, but the second sentence is irrelevant boilerplate for a read tool, and brevity here is under-specification rather than economy.

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?

An output schema exists so return values needn't be explained, but a paginated list tool with default/max limits and a search filter must describe paging and filtering behavior. Neither the description nor the schema covers this, leaving the agent without enough to call it 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?

Schema description coverage is 0% for three parameters (limit with max 100 and default 50, offset, search), and the description says nothing about any of them. With zero schema documentation, the description had full responsibility to explain paging and search semantics and 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 says only 'Read milestone', which restates the resource without clarifying that this returns a paginated collection of milestones. It fails to distinguish the tool from siblings like get_milestone (single record), get_milestone_matrix, or list_milestone_column.

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 statement of when to use this tool versus get_milestone or the other milestone listers, and no prerequisites or exclusions. The approval-requirements sentence is boilerplate that gives no routing guidance.

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