Create several tasks

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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=false. The description adds the batch behavior and per-entry list targeting, but does not disclose partial-failure semantics, atomicity, or return behavior. Given the annotations present, this is acceptable but not rich.

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 concise sentences that are front-loaded with the core action, immediately followed by usage guidance and a useful nuance. No filler or redundancy.

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 description covers purpose, usage, and one behavioral nuance, but for a batch mutation tool it omits important operational details such as atomicity, partial-failure handling, and whether created tasks are returned. Given no output schema, some of this context would be valuable for the agent.

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 parameters are fully documented. The description adds meaningful semantic value by clarifying that each array entry can target a distinct list, which informs the use of the optional 'list_id' field beyond what the schema states.

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 uses the specific verb 'Add' with the resource 'several tasks at once', clearly distinguishing this batch operation from the sibling 'create_task'. It also names the exact scenario ('when the user lists multiple things') and notes that entries may target different lists.

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?

Provides explicit guidance: 'Use this instead of repeated create_task calls when the user lists multiple things.' This tells the agent when to use this tool and which alternative to avoid, effectively covering both the when and the when-not.

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