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

The description goes well beyond annotations by disclosing login requirements, notification side effects, collaborator authorization constraints, non-idempotency with no dedup key, and the recommended verification workflow. These are substantive behavioral facts that annotations alone do not convey, and nothing contradicts the annotations.

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 dense but well-structured, front-loading the core action and login requirement before important caveats. Every sentence carries meaningful guidance about authorization, idempotency, notifications, or verification, with no filler.

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 side-effecting, non-idempotent creation tool with no output schema, the description covers the most important operational concerns: authorization, notification, timeout handling, and verification via get_collaboration_goal. It does not explicitly describe the success return value, but its verification guidance effectively compensates for that gap.

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 only 20%, so the description must compensate. It does clarify assigneeId semantics (omitted means self, must be a goal collaborator if specified), but it does not explain title, detail, or goalId meaning beyond obvious inference, and dueAt semantics are left to the schema. That is partial compensation for a low-coverage schema.

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 and resource: creating a task within a collaboration goal, and it explicitly covers assignment behavior when assigneeId is provided. This distinguishes it from siblings like create_collaboration_goal and update_collaboration_task, since it is clearly about task creation/assignment rather than goal creation or task modification.

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 gives clear usage context: call only after the user authorizes assigning to a collaborator, use get_collaboration_goal to verify before/after creation, and do not auto-retry on timeout or unclear results. It does not explicitly mention update_collaboration_task as the alternative for changing an existing task, so it stops short of a full when-not-to-use statement.

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