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

Goes well beyond annotations: discloses login requirement, permission scoping, serial execution with partial-success outcomes, and the ethical constraint of not marking completion for others. It also explains the updated/failed result shape, which annotations (idempotent, non-destructive, openWorld) cannot convey.

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?

Dense but well-structured with bracketed sections (需要登录 / 组合链 / 口径·坑) that front-load the login gate and the call chain. Every line carries operational content, though the block is longer than strictly minimal.

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 batch mutation tool with no output schema, it covers prerequisites, permissions, downstream result handling (updated/failed), execution semantics, and the sourcing of required ids, leaving nothing an agent needs to call it correctly unaddressed.

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 the schema documents the items array and enum itself, but the description adds real value by specifying the combo chain (derive organizationId and taskId from list_my_organization_tasks items[]) and noting the per-call batch limit context. This is above the schema-coverage baseline.

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 (改/set status) and resource (organization task) and even enumerates the target status values (TODO/DOING/DONE/CANCELLED) plus the batch nature. It also distinguishes itself from create_organization_task, which handles newly assigned tasks, so an agent can route correctly among siblings.

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 states when to use it (reporting status via a batch), the prerequisite (login required), and a key restriction (non-managers may only change tasks assigned to themselves). It names the alternative create_organization_task for assigning new work and notes AI division suggestions belong in App/web, giving clear when/when-not guidance.

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