update_bulk_tasks

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the bulk nature and efficiency, but doesn't disclose important behavioral traits like whether this requires specific permissions, whether updates are atomic or partial, what happens on partial failures, rate limits, or what the response looks like. For a mutation tool with zero annotation coverage, this is inadequate.

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 extremely concise and well-structured. The first sentence establishes purpose, followed by clear bullet points for identification requirements, and a final sentence about partial updates. Every sentence earns its place with zero waste.

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 this is a mutation tool with no annotations and no output schema, the description is incomplete. It doesn't address critical contextual information like authentication requirements, error handling, response format, or performance characteristics. The partial update statement is helpful but insufficient for a bulk mutation operation.

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%, so the schema already documents all parameters thoroughly. The description adds minimal value beyond the schema by emphasizing the identification requirements (taskId preferred, taskName requires listName) and the partial update behavior. This meets the baseline 3 for high schema coverage.

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 clearly states the verb ('Update') and resource ('multiple tasks'), and specifies the scope ('efficiently'). It distinguishes from siblings like 'update_task' (singular) and 'update_list' (different resource), but doesn't explicitly contrast with 'move_bulk_tasks' or 'delete_bulk_tasks' which also operate on multiple tasks.

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 provides implied usage guidance by specifying identification requirements (taskId alone preferred, or taskName+listName) and stating 'Only specified fields will be updated.' However, it doesn't explicitly state when to use this tool versus alternatives like 'update_task' (singular) or 'move_bulk_tasks', nor does it mention prerequisites or exclusions.

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