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

Annotations already declare readOnlyHint=true, so the description is not burdened with basic safety. It adds value by specifying scope ('the caller's') and content ('settings, payment methods enabled'), which goes beyond the annotation. No contradictions.

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 plus the endpoint. Every word is informative with no waste. Front-loaded with the key verb and resource. Ideal conciseness.

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?

Tool has no parameters or output schema, so complexity is low. The description covers purpose and scope adequately. However, it could briefly mention that it returns the full organization object to avoid uncertainty, but not essential.

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?

No parameters exist, so schema coverage is 100%. The description does not need to add parameter details. Baseline of 4 is appropriate as there is nothing missing.

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?

Clearly states the verb 'Get', resource 'organization configuration', and provides specific examples of what it returns ('settings, payment methods enabled'). The HTTP path further confirms the action. Distinguishes from sibling tools like 'get_entity' which target entities rather than the organization.

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?

Implies usage for retrieving the caller's own organization config, but provides no explicit guidance on when to use vs alternatives, nor any when-not-to-use conditions. Lacks exclusions or context that would help an agent decide between this and related tools like 'mercoa_get_entity'.

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