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

Annotations already declare idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful behavior: login requirement, the non-manager self-only restriction, serial execution with partial-success being normal, and the need to report updated/failed honestly. Only error semantics for invalid IDs/statuses are left unstated.

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?

Organized into clearly labeled sections (login/chain/pitfalls) that are front-loaded and each carry distinct information. Dense but not padded; slightly verbose for a single-parameter tool.

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?

With no output schema, the description usefully explains the updated/failed response shape, plus auth, permission, and partial-success caveats. Complete enough to invoke correctly, though it does not cover how to interpret or recover from failed entries.

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% and the nested items object documents organizationId, taskId, and status with enum values. The description restates the state enum and the batch behavior, which adds little beyond the schema, so the baseline 3 applies.

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+resource (改组织任务状态) and enumerates the allowed target states TODO/DOING/DONE/CANCELLED, plus the batch nature. It explicitly distinguishes itself from create_organization_task, so an agent can route correctly among the many sibling task tools.

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?

Gives an explicit composition chain (list_my_organization_tasks → this tool → report updated/failed) and names the alternative for a different intent (managers creating tasks use create_organization_task). It also states the permission condition for non-managers.

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