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. "Return" implies a read, but the description never states permissions, whether anything is mutated, rate limits, or what the evidence output actually contains.

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 front-loaded sentence with no filler sentences. It loses a point only because the jargon-dense phrasing ("buyer-ready drift controls") adds words without adding meaning.

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?

An output schema exists, so return-value explanation is not required, but with four undocumented parameters and no annotations, the description is far too thin for an agent to invoke this correctly or route to it over its many siblings.

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 four parameters (check_id, decision, source_id, protocol_id), and the description mentions none of them. The description provides no compensating meaning for what these identifiers select or how they interact.

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?

States a verb ("Return") and a resource ("MCP/A2A protocol conformance evidence"), which is more than a tautology, but "buyer-ready drift controls" is marketing jargon rather than a concrete deliverable. It gives no basis to distinguish it from close siblings like recipes_mcp_authorization_conformance_pack or recipes_mcp_tool_surface_drift_pack.

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 when-to-use guidance, no prerequisites, and no mention of alternatives among the ~60 sibling "pack" tools. The agent is left to infer selection from the name alone.

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