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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is fully covered by structured data. The description contributes nothing beyond that — no mention of what the response contains, whether it is scoped to a period, or what 'unassigned' implies.

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 endpoint path is duplicated verbatim in consecutive sentences, which is waste rather than conciseness. The operation ID and describe_operation pointer are the only non-redundant content.

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?

No output schema exists, so the description carries the burden of describing the return shape, and it does not. Combined with a 0%-documented parameter schema and a vague resource noun ('unassigned'), an agent cannot confidently call or interpret this tool.

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 0% and the description says nothing about the two parameters (an open-ended 'query' object and an empty 'params' object). For an endpoint whose only filtering mechanism is an untyped query blob, the description should explain accepted query keys, and it does not.

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 only repeats the raw endpoint path twice; it restates the title rather than explaining what 'unassigned leases' means in a journal-close context. An agent gets a resource path but no semantics to distinguish this from the dozens of sibling journal-close GET tools (batches, runs, profiles, setups).

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 when-to-use, when-not-to-use, or alternative guidance is given. The only actionable hint is the pointer to describe_operation for native request schemas, which is a meta-instruction rather than usage context.

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