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

Description claims idempotency ('Idempotently initialize') but annotations set idempotentHint=false, a direct contradiction. No other behavioral details provided.

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?

Two succinct sentences with key information front-loaded. Every word adds value without redundancy.

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?

While an output schema exists, the description omits critical input context (engagement_id, milestones structure). For a tool with two parameters and nested objects, this is insufficient.

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%, and the description adds no parameter-specific meaning. It fails to explain the engagement_id or milestones array, despite the schema having complex nested fields.

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?

Description clearly states 'initialize stable engagement milestones' with a specific verb and resource. The idempotency mention and retry behavior distinguish it from sibling tools like update_consulting_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?

Implies use for initial setup via 'initialize' and idempotency, but does not explicitly state when to use versus update_consulting_milestone or other alternatives. No exclusion criteria provided.

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