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

With no annotations, the description carries the behavioral burden. 'Return' signals a retrieval/report-like operation, which is a useful non-destructive cue, but it does not disclose whether checks run live, whether drift controls take action, or what inputs are required. Minimal but not misleading.

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?

A single sentence with no filler and the main noun phrase front-loaded. 'Buyer-ready drift controls' is jargon, but the structure is concise and easy to scan.

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 tool with four optional inputs, zero annotations, and dozens of closely related sibling tools, a one-sentence description is insufficient. The output schema may cover return values, but input semantics and tool-selection context are missing.

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 does not explain check_id, decision, source_id, or protocol_id. An agent cannot tell whether these are filters, identifiers, output selections, or configuration decisions; the parameter names provide only weak guesses.

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?

Names a specific deliverable (MCP/A2A protocol conformance evidence and buyer-ready drift controls) with a clear verb (Return), so an agent can tell what the tool does. It is distinguishable from generic sibling packs by its explicit protocol-conformance focus, though 'buyer-ready drift controls' remains somewhat vague.

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?

There is no guidance about when to use this tool versus the many sibling conformance, evidence, and control packs. The description implies a protocol-conformance use case, but it never states prerequisites, alternatives, or exclusion conditions.

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