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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds useful behavior: passing a requirement id returns one item, omitting it returns all, no credential is needed, and results include properties, alternative implementations, and remediation/verification commands. No contradiction with annotations exists.

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 front-loaded with the primary use case and then compactly explains scope, behavior, and invocation. It is dense but not bloated; every sentence contributes useful information. A slightly tighter structure would be possible, but the current form remains efficient.

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 simple optional-parameter schema, rich annotations, and lack of an output schema, the description provides enough context for correct invocation: what the tool reads, how to select a single requirement, that credentials are unnecessary, and what kinds of information are returned. It does not describe the exact response shape, but that is a minor gap for this read-only lookup tool.

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?

The schema already documents the single optional 'requirement' parameter with an example, achieving 100% coverage. The description adds practical semantics by clarifying that omission reads the entire standard and that the parameter selects a single finding, which helps an agent decide how to invoke the tool.

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 specific resource (the provider-neutral production requirements standard), a clear verb context ('know what a production finding means'), and gives a concrete example like TC-PROD-0041 from the productionize CLI. It clearly differentiates this from other capability-exploration tools by focusing on the standard itself and its remediation commands.

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 explicitly states when to use the tool ('Use this when you need to know what a production finding means, or what production actually requires') and how to tailor the call. It does not explicitly mention when not to use it or name sibling alternatives, so it falls just short of full guidance.

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