Checklist Schedule Assignee Filter Options

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds only that it returns a JSON array of filter values, which is minimal. It does not disclose pagination behavior, performance, or other constraints beyond what annotations infer.

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 three sentences: purpose, usage context, and API reference. It is concise and front-loaded, but the API endpoint line is somewhat duplicative of the title. No unnecessary fluff.

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?

Given the low complexity (3 parameters, no output schema, good annotations), the description covers the core purpose and return type. However, it does not explain pagination parameters or the impact of the 'page' and 'per_page' parameters, which are in the schema but lack context.

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 coverage is 100%, with each parameter having a description. The description mentions that project_id is required but adds no additional meaning on top of the schema. Baseline 3 is appropriate.

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 tool is used to populate a filter UI with valid values for Inspections, and the name and title specify "assignee". However, it does not explicitly differentiate this tool from sibling filter option tools (e.g., equipment, location), relying on the name alone.

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 says "Use this to populate a filter UI" but gives no guidance on when to use this tool versus alternatives like other filter tools. No exclusions or context on prerequisites beyond project_id.

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