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

With no annotations provided, the description carries the full behavioral burden, and it does substantial work: it explains what a resolved response includes, warns against claiming success on unresolved outcomes, and discloses that Knowbase validates recipe/statuses but does not inspect the caller's environment or authenticate the lookup id. It does not detail side effects or error responses, but the key trust and boundary information is present.

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 compact and front-loaded, opening with the tool's role in the workflow and then covering action, success criteria, failure handling, and validation boundaries in four efficient sentences. Every sentence contributes distinct information, and there is no filler or redundant schema repetition.

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 (7 required parameters, no output schema, no annotations), the description provides a solid workflow anchor and explains the high-level output contract (receipt and final report) plus the unresolved/inconclusive behavior. It does not fully specify the response structure beyond that, but the rich parameter schema compensates for most 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?

Schema description coverage is 100%, and each parameter already has a clear description, including the important 'returned by diagnosis' relationship and the criterion status enum. The description adds a high-level instruction to submit the ids and observations, but this largely restates what the schema already communicates. The baseline of 3 is appropriate because the schema is doing 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 a concrete action ('Close the loop after knowbase_diagnose identifies a structured resolution') and specifies what the tool does: apply every listed step, run every verification criterion, and submit ids and observations. This clearly distinguishes it from sibling tools because it is explicitly positioned as the post-diagnosis completion step.

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 clearly states when the tool is appropriate: after knowbase_diagnose has identified a structured resolution. It also provides behavioral guidance for unresolved or verification_inconclusive responses, telling the agent not to claim success, to follow nextAction, and to call the tool again. It does not exhaustively contrast against every sibling, but the sequential relationship to knowbase_diagnose is clear.

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