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

The description mentions 'pending event with escrow hold' and '[Auth Required]', disclosing key side effects and authentication needs. However, it does not cover other behavioral aspects like failure modes, idempotency, or whether the hold is reversible. With no annotations, the burden is higher.

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 extremely concise: one sentence plus an auth prefix. Every word adds value, and the auth requirement is front-loaded. No unnecessary detail.

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 no output schema, the description should mention what the tool returns (e.g., event details). It only says 'creates a pending event', missing return value. Parameter coverage is adequate, but overall completeness is minimal.

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?

Input schema coverage is 100% with good descriptions for all 5 parameters. The tool description adds no additional meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

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 books a time slot with a specialist and creates a pending event with escrow hold. The verb 'book' and resource 'event' are specific and distinguish it from sibling tools like search-specialists or create-contract-event.

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 the tool is for booking a specialist but provides no explicit guidance on when to use it versus alternatives, nor any exclusion criteria. The auth requirement is noted but not elaborated.

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