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

Goes well beyond the destructiveHint/idempotentHint annotations by disclosing cascade effects: machine grants generated through the pool grant are revoked and dependent processes are stopped, while the pool itself survives. It also states there are no dependency blockers, which is exactly the risk information an agent needs before a destructive call.

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?

Two dense sentences with zero filler; the destructive consequence is front-loaded and the reassuring non-effects (pool retained, no blockers) follow. Every clause earns its place.

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 destructive tool with an output schema absent and annotations limited to boolean hints, the description fully covers what is destroyed, what is preserved, and whether blockers exist. Nothing needed to call it correctly is missing.

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 100% with all three IDs documented (orgID, projectID, poolGrantID with patterns), so the schema carries full parameter meaning. The description adds no additional parameter syntax or format detail, making the baseline 3 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?

States specific verbs and resource: removes the project's access to the machine pool and revokes the associated grants. It also distinguishes itself from the sibling pools_delete by explicitly noting 'The pool itself is retained', so an agent can tell it apart without opening the schema.

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 purpose is clear, but there is no explicit when-to-use or when-not guidance and no named alternative among the grant_pools_* and pools_delete siblings. Usage is implied by the tool name rather than stated.

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