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 and largely drops it. It never states whether validation is synchronous, idempotent, or side-effect-free, whether it consumes credits or places any real call, or what happens on a failing validation. For a tool whose name suggests executing a test, the absence of any safety or side-effect disclosure is a significant gap.

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?

Three short sentences with the purpose stated first and the disambiguation second; nothing is padded. It is efficiently sized for the small amount of information it actually conveys.

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?

With three required parameters, no annotations, and no output schema, the description is the only source of behavioral and return information, and it omits both. An agent cannot tell what a successful validation returns, whether failures are surfaced as errors or results, or how to act on the outcome.

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% across three required parameters (workspaceId, id, revision), and the description explains none of them. The phrase 'the current draft' loosely gestures at the id/revision pair but gives no guidance on which revision must be supplied or whether the draft must already be saved, so the schema remains undocumented from both sources.

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 gives a verb ('validate') but the resource is referred to only as 'the current draft', never naming agents or the draft artifact, so the agent must infer scope from the tool name. The clarifying sentence 'this is configuration validation, not a voice-quality score' usefully narrows what kind of validation is performed, but it does not distinguish this from close siblings such as agents_save or agents_publish.

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?

'Use a draft SIP call to hear the result' implies the tool is meant for pre-publish validation of a draft, which is a real usage hint. However, it never states when to call this versus agents_save, agents_publish, or lines_test, nor any prerequisite (e.g., an existing draft revision must be saved first), leaving routing largely to inference.

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