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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior. The description adds useful scope: only metadata/approved fields are returned, and secrets, contacts, and original files are excluded. It could say more about pagination or authorization requirements, but it meaningfully extends the annotation-level safety profile.

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?

Two sentences, front-loaded with the main action and followed by a useful field-scope caveat. The phrase 'through the existing application' is mild filler, but overall it is compact and readable.

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?

No output schema exists, and the description does not compensate by explaining the shape of returned requirement records or the meaning of targetId. For a four-parameter list tool with zero schema descriptions, this leaves the agent under-informed about how to invoke it correctly.

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 there are four parameters, including the required targetId. The description does not explain targetId, query, limit, or offset, so the most important input semantics are entirely absent.

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 states a read operation over 'credential ce requirements,' which is a recognizable resource, but 'ce' is never expanded and 'through the existing application' adds ambiguity rather than precision. It also does not distinguish this tool from nearby siblings such as list_ce_requirements or search_credential_requirements.

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 the many credential/CE-related siblings. The description implies a filtered read but gives no conditions, prerequisites, or exclusions.

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