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

Annotations already declare the safety profile: not read-only, not destructive, idempotent, and not open-world. The description adds that the operation concerns Google Calendar sync, which is useful context, but it does not explain side effects, auth requirements, or what happens to already-synced data.

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, front-loaded sentence with no wasted words. It is appropriately sized for a simple one-parameter disconnect operation.

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 the tool's simplicity, full schema coverage, and annotations covering safety, the description is nearly complete. It could be improved by clarifying whether existing calendar data remains intact or whether reconnection is possible, but nothing essential is missing for calling 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 description coverage is 100%, and the single calendarId parameter is fully documented as a Calendar UUID in the schema. The description mentions 'a calendar' but adds no further meaning beyond what the schema already provides, so the baseline of 3 applies.

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 gives a specific verb (Disconnect) and resource (a calendar from Google Calendar sync), making the action clear. It does not explicitly distinguish this from sibling tools like neuron_delete_calendar or neuron_google_calendar_status, so it misses the top score.

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 offers no when-to-use guidance, prerequisites, or alternatives. It does not say when to choose this over deleting a calendar or checking sync status, leaving the agent to infer usage entirely from the tool name.

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