bulk_update_tasks

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

With no annotations, the description carries the full burden of behavioral disclosure. It states the core behavior (same changes applied to all taskIds) but does not disclose failure semantics (e.g., partial failures if some IDs are invalid), atomicity, whether unspecified fields are overwritten, or any permission/rate concerns. For a mutating bulk operation, this is a significant gap.

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 two sentences, front-loaded with the main purpose, and contains no unnecessary words. It is efficient and easy to scan.

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?

The tool is complex (nested updates object, many optional fields, potential partial failures) and has no output schema or annotations. The description covers what and when but omits behavior like error handling, return format, and update semantics. It is minimally adequate but leaves room for improvement.

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 baseline is 3. The description adds minimal semantic value beyond the schema: it only clarifies that updates apply to all taskIds. Parameter-level details are already well documented in the 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 clearly states the tool updates multiple tasks simultaneously with the same changes, using a specific verb and resource (update tasks) and a distinctive qualifier (multiple/simultaneously). It distinguishes well from siblings like update_task (single task) and bulk_change_status (status-only).

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?

It explicitly identifies batch operations as the use case and provides examples (changing assignees or priorities). However, it does not explicitly state when not to use it (e.g., when each task needs different changes) or mention alternatives like update_task, so it lacks a clear exclusion.

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