workspace_release

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

The description states 'Idempotent' while annotations set idempotentHint=false, which is a direct contradiction. This is a serious inconsistency that undermines trust in the tool's behavioral metadata.

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?

Three sentences, all essential: action, idempotency, side effects, and a misuse caution. No wasted words.

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?

For a simple one-parameter tool, the description covers purpose, side effects, and safety considerations. However, the contradiction with annotations and lack of error-case detail keep it from a perfect score.

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?

Only 'lease_id' is mentioned by name, with no additional meaning beyond the schema. With 0% schema description coverage and one parameter, the description fails to compensate by explaining the format, source, or behavior related to the lease_id.

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 an exclusive workspace lease') with a specific resource and identifier ('by lease_id'). It distinguishes itself from sibling tools like workspace_acquire and workspace_status.

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?

Provides clear context on use (release a lease) and a critical caution ('Do not use to steal another writer's lease unless you possess their lease_id'). It does not explicitly name alternatives, but the when-not-to-use guidance is valuable.

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