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

Annotations already indicate destructive and idempotent behavior, so the description should add context beyond that. It mentions 'privacy-filtered project metadata' but does not clarify side effects, permissions, or what gets destroyed. The term 'Update' may also be misleading relative to the tool name 'cancel_queue_item'.

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 sentence, but it is not concise in a meaningful way – it is vague and does not provide actionable information. It could be longer to be useful, so it is under-specified rather than efficiently concise.

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 operation with 6 parameters and no output schema, the description is severely incomplete. It does not explain the effect, prerequisites, return value, or when to use it. The agent would be left guessing how to invoke it correctly.

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 coverage is 0%, meaning the description must explain parameters, but it does not. No mention of projectId, queueItemId, expectedVersion, idempotencyKey, or sessionId/executionId. The phrase 'project metadata' does not clarify parameter semantics.

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 states a specific action ('Update') and a resource ('hosted cancel queue item'), which is fairly clear. However, it does not distinguish from siblings like 'update_queue_item' or 'cancel_queue_type', and the phrase 'using privacy-filtered project metadata' is vague and unexplained.

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?

No guidance is given on when to use this tool versus alternatives such as 'cancel_queue_type' or 'preview_queue_type_cancel'. The description does not mention any conditions, exclusions, or recommended usage scenarios.

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