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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only restates the action without mentioning side effects, such as what happens to the job after acknowledgment, whether it deletes the job, or any required permissions. This is a significant gap for a mutation tool.

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, concise sentence with no wasted words. It captures the essential action and target efficiently.

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?

Given the tool's complexity (3 parameters, no annotations, no output schema), the description is too sparse. It doesn't explain behavior after ack/nack, whether action is optional or defaults, or any prerequisites like having a lease. This makes the tool harder to use correctly without additional context.

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 only 33% (id has a description; job_id description is empty; action only has an enum). The description adds some meaning by explaining action as ack/nack and implying that job_id refers to the leased job. However, it doesn't fully compensate for the low coverage, leaving ambiguity around the default action and the id's role beyond being a queue identifier.

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 states the action (acknowledge/nack) and the target (a leased job). It distinguishes from sibling queue tools like queue_lease and queue_push by its specific verb and object, though it doesn't explicitly name alternatives.

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?

Usage is implied: you use this tool when you have a leased job and want to acknowledge or nack it. However, there is no explicit guidance on when to use it instead of other queue tools, nor are alternatives or exclusions mentioned.

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