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

No annotations are provided, so the description carries the full burden. It mentions settling the earliest pending delivery, but it does not explain prerequisites, side effects, reversibility, ownership requirements, or what exactly 'approve your task' entails. The alias note is useful but does not disclose the underlying behavior in enough detail.

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 a single compact sentence that combines purpose, behavior, and usage guidance without redundancy. It front-loads the alias relationship and includes the usage preference parenthetically, making it efficient for an agent to parse.

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 simple one-parameter compatibility alias, the description gives enough to route an agent toward pick_task and to understand the basic action. However, with no annotations and no output schema, the lack of behavioral detail and expected return behavior leaves moderate gaps.

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?

The schema fully documents task_id with an example format, so the baseline is 3. The description does not add additional parameter-level meaning beyond what the schema already provides.

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 identifies approve_task as a compatibility alias for pick_task and states the intended action: approving a task and settling the earliest pending delivery. It is specific enough to convey the tool's role, though it relies somewhat on the sibling pick_task to fully define behavior.

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?

The description explicitly says the tool is 'kept for older agents' and instructs agents to 'prefer pick_task'. This gives clear guidance on when to use this tool versus the preferred alternative.

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