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

Annotations already mark destructiveHint true. The description adds key context: it is terminal (irreversible) and that an optional reason is recorded for audit, which goes beyond the annotation's binary indication.

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 three sentences, each adding value: purpose, usage scope, and important notes (terminal, audit). It is front-loaded and efficient, though could be slightly more structured.

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 and simple action, the description covers who, when, what, and important caveats. It is adequate for an agent to correctly invoke the tool.

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?

With 0% schema coverage, the description must add meaning. It identifies required params (community_id, booking_id) and explains reason is optional for audit. However, it doesn't describe the format or constraints beyond the schema's min/max lengths.

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 action 'release a venue booking' and its effect 'frees the Space's slot'. It distinguishes from siblings like 'cancel_event' by emphasizing it frees a slot and is terminal.

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 specifies who can use it (community creator/admin/moderator or the host) and that it's terminal. It doesn't explicitly name alternatives but the context implies this is for releasing slots, which is distinct from other operations like cancel_event.

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