Manage Task List

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=false, establishing a mutating, destructive profile. The description's action list is consistent with those annotations and adds the concrete 'clear completed tasks' behavior, but it doesn't disclose consequences such as whether delete or clear_completed are permanent or whether update merges or replaces list properties. It adds some value beyond annotations without contradicting them.

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?

A single 11-word sentence with zero filler; the action list is front-loaded immediately after naming the resource. The only minor redundancy is that 'Manage task lists' closely echoes the tool title, but the colon-structured format is efficient and scannable.

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 structured data carries most of the burden: a full output schema covers return values, per-parameter schema descriptions cover inputs, and annotations cover the safety profile. The main gap is that action-selection semantics—which task_list_id applies to which action and what clear_completed actually does—are only implied by the schema, not explained in the description. Adequate for a well-annotated tool, but not rich.

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 every parameter (title, action, task_list_id, user_google_email) already has a documented description, including which actions require which fields. The description only restates the action enum values already present in the schema, adding no new meaning. The baseline 3 applies since the schema does the heavy lifting.

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 names the resource (task lists) and enumerates four concrete actions (create, update, delete, clear completed), which makes the tool's scope specific. It is implicitly distinguished from siblings: manage_task operates on individual tasks, and list_task_lists/get_task_list are read-only counterparts. The generic opener 'Manage' is slightly weak, but the action enumeration compensates.

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?

No guidance is given on when to use this tool versus alternatives. The description never mentions that list_task_lists/get_task_list are the read-only options for task lists, nor that manage_task handles individual tasks, and it doesn't explain when each action (create vs update vs delete vs clear_completed) is appropriate. With dozens of siblings, the agent must infer selection entirely from the schema.

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