subscribe_to_object_notifications

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

Description contradicts annotation: description claims idempotent when already subscribed, but annotation has idempotentHint: false. Also destructiveHint: true is consistent, but contradiction lowers score.

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 sentences, no redundancy. Front-loaded with main action, efficient.

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?

Covers core purpose but lacks usage guidance and behavioral details. Output schema exists, so return values not needed. Gap in idempotency explanation.

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 100%, so baseline 3. Description adds no parameter-specific meaning beyond schema's 'a string that will be trimmed'.

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?

Description clearly states the action (subscribe), target (notifications for raw Huly object), and mechanism (adding core collaborator row). It also notes idempotency. Distinct from sibling tool 'unsubscribe_from_object_notifications'.

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 explicit when-to-use or alternatives, but the description implies it is for subscribing to notifications via collaborator mechanism. However, it doesn't differentiate from sibling 'add_object_collaborator' which might have similar effect.

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