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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, and the description confirms nothing beyond that. It does not disclose what the response contains, whether a missing ID errors or returns empty, or any permissions/rate-limit context.

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 one substantive sentence is duplicated verbatim, and the operation ID and describe_operation pointer are boilerplate. Brevity is there, but every sentence is either repeated or administrative, so no information is front-loaded beyond the raw route.

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?

With no output schema, the description carries the burden of saying what a CAM period object contains (period dates, lease scope, status) and it says nothing. For a nested-object, 0%-coverage, no-output-schema tool, the definition is not complete enough for confident selection or result interpretation.

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 the description adds nothing about periodId — no format (UUID vs. numeric), no source (where to obtain a period ID), and no mention of the optional free-form query object. Only the ':periodId' path token hints that it is a path parameter, which is minimal compensation for a 0%-coverage schema.

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 route string 'GET /api/cam/periods/:periodId' conveys a verb and resource, so the agent can infer this fetches a single CAM period by ID. But it is never stated in plain language, and nothing distinguishes it from siblings such as get_cam_periods_2dd78ed797a3dcb9f48dc89e (the collection) or the many get_cam_periods_by_periodId_* sub-resource endpoints.

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 CAM periods list endpoint or the period sub-resource endpoints. The only actionable hint, 'describe_operation provides native request schemas', is a pointer to another tool for schema lookup, not usage guidance.

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