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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior, but the description adds useful data-exposure boundaries: metadata/approved fields only, with no secrets, contacts, or original files. That is meaningful behavioral context beyond the annotations, though authentication requirements and pagination behavior remain unspecified.

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 short and front-loads the read/data-scope constraint efficiently. Minor wording like 'through the existing application' is slightly vague but not enough to undermine its brevity.

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 list tool with no output schema and three undocumented parameters, the description omits return fields, pagination behavior, and query semantics. It covers data sensitivity well but is not complete enough for reliable invocation.

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 has three parameters with 0% description coverage, and the description says nothing about limit, query, or offset. The agent receives no explanation of query matching semantics, pagination limits, or expected filtering behavior.

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 clearly states a read operation over CE requirements, matching the tool name and resource. However, it does not distinguish this list tool from nearby siblings such as list_credential_ce_requirements or search_credential_requirements, leaving ambiguity about which CE-requirement access pattern this tool serves.

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 on when to use this tool versus alternatives, no stated preconditions, and no exclusions beyond the data-scope note. The agent must infer that this is a general listing endpoint 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.
