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

No annotations are provided, so the description carries the full behavioral burden. 'in place' implies mutation and the at-least-one-field rule is disclosed, but there is no information on permissions, whether edits are reversible, how unspecified fields are treated, or the null-to-clear semantics (which live only in the schema).

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?

Two tightly written sentences with zero waste. The mutation action is front-loaded and the constraint sentence follows logically.

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 mutation tool with no annotations and no output schema, the description covers the action and one constraint but omits behavioral aspects like permission requirements and handling of unmentioned fields. High schema coverage (88%) partially compensates, keeping this adequate but not complete.

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 88%, so the schema already documents parameters (including null-to-clear semantics) thoroughly; baseline 3 applies. The description names some mutable fields but adds no syntax or format detail beyond what the schema 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?

Clear verb ('Edit') + resource ('report') + enumerated mutable fields (title, description, HTML, producer attribution). An agent can distinguish it from create_report/get_report without opening the schema, though it doesn't explicitly name a sibling as the alternative.

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 only guidance is the validation constraint that at least one mutable field must be provided. There is no when-to-use context, no mention of the read/create/delete siblings, and no prerequisites such as ownership or permissions.

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