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

Annotations already declare destructive, idempotent, and open-world behavior, and the description adds genuinely new context beyond them: webhooks, workspace notifications, and automation-rule triggers that fire as side effects, plus the note that permissions are enforced at workspace, project, and account level. It stops short of describing what happens on a stale-version conflict, which is the main behavioral unknown left for a concurrency-controlled mutation.

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?

Six short sentences, front-loaded with the action and the version precondition, then the bulk alternative, then retry and permission notes. Every sentence carries information an agent needs to invoke this correctly; nothing is restated from the schema or annotations.

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 5-param destructive mutation with nested patch objects and no output schema, the description covers versioning, side effects, permissions, and idempotent retry, which is most of what an agent needs. The one notable omission is conflict behavior when the supplied version is stale.

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 40%, so the description must compensate, and it does for the two hardest required params: it explains that version must come from get_tasks/get_items/get_workspace, and that requestId must be unique and reused specifically when retrying the same action. It says nothing about placement or how patch fields interact, so it does not fully close the coverage gap.

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 a specific verb and resource set ('Update an authorized project, task, or resource') and adds the key qualifier 'using its current version', which is the distinguishing mechanic of this tool. It also names the sibling it is not (items_update) so the agent can separate it from the bulk variant without opening either 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?

Explicitly routes bulk work to items_update, and states the precondition that the caller must first obtain the current version via get_tasks, get_items, or get_workspace. It also gives retry guidance tied to requestId, which is a when-to-use condition in practice.

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