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

With no annotations, the description carries the transparency burden. It conveys that this is a read operation via 'Retrieve' and describes the return format as 'structured sequences with delegation readiness signals'. However, it does not disclose safety/read-only status explicitly or mention any limitations, permissions, or error conditions, leaving some gaps.

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 two concise sentences. It front-loads the primary action, provides a clarifying parenthetical, lists filters, and states the return type. Every sentence contributes meaningful information with no redundancy.

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?

The tool is a relatively simple get/filter operation with optional parameters and an output schema, so the description does not need to detail return values. It covers purpose, key filters, and return format. It is slightly incomplete in not describing the operator_id parameter or exhaustive cadence/delegation values, but overall it is adequate for selecting and invoking the 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?

Schema description coverage is 0%, so the description must compensate. It mentions 'cadence (daily, weekly, monthly)' and 'delegation status', but the enum values are incomplete (missing quarterly/event_triggered and the delegation_status values). It does not mention the operator_id parameter at all, which is a required input concept for scoping the records.

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 the verb 'Retrieve' and the resource 'operating rhythm records for an operator', with an explanatory parenthetical that distinguishes the concept from calendar data. It is specific and differentiates from sibling tools like get_operator_profile or get_signals_feed by focusing on temporal behavioral patterns.

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 provides clear context on when to use the tool by framing it as capturing actual human behavior 'not what their calendar says'. It also mentions filterability by cadence and delegation status, which suggests use cases, but it does not explicitly name exclusions or alternatives.

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