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

With no annotations, the description carries the full burden and does well: it discloses atomic compare-and-swap behavior, exactly-one-winner semantics, the 409 outranked payload, invitee echo/visibility to the owner, and conferencing link attachment. It leaves idempotency_key semantics and permission/auth expectations unexplained.

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 front-loaded with the core finalize/CAS behavior, then optional fields and conferencing. Three short paragraphs with no wasted sentences; every part adds useful invocation or behavioral context.

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?

The core commit semantics and conflict behavior are complete, and an output schema exists to cover return values. But for a 7-parameter mutation with no annotations and 0% schema coverage, the description should also explain idempotency_key, metadata, and start/end expectations.

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 for all parameter meaning. It explains title, invitee shape, and with_conferencing, but omits start/end format expectations, metadata, and critically the idempotency_key, leaving several parameters undocumented.

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?

States a specific verb and resource ('Finalize a booking') and adds the distinguishing concurrency semantics: atomic compare-and-swap at slot level, exactly one agent succeeds per race window. This clearly separates it from hold/cancel/approval siblings without needing their schemas.

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 usage context: commit a slot that is being finalized, with conflict behavior on 409. However, it does not explicitly say when to use this versus create_hold, or when not to use it, so the guidance remains implied rather than explicit.

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