file_release

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

The description adds specific behavior (releasing reservations) beyond the annotations (readOnlyHint: false, idempotentHint: true), but it does not disclose side effects, error conditions, or what happens if the reservation does not exist or is already released.

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 a single, focused sentence with no redundancy. It is appropriately short for the simple action it describes, though it omits crucial details that would make it more useful.

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 description lacks essential context such as when to use the tool, prerequisites, or behavioral nuances. Since there is no output schema, it also does not clarify expected outcomes, leaving the tool under-specified for practical use.

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?

The description does not explain any of the parameters (e.g., agent, patterns, lease_id). It gives no indication of how parameters affect the operation, leaving the schema to carry the full burden without any supplemental clarification.

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) and the resource (file reservations) with a specific context (held by an agent). It is concise and distinct from sibling tools like file_reserve and file_renew.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites, or any conditions that warrant its use. It only states what it does, not when to call it.

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