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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered externally. The description adds useful context about the computed metrics and the date-range scoping, but says nothing about return format, aggregation granularity, or whether results are paginated.

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 resource and metric set, zero filler. Every clause carries information.

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 three optional params, no output schema, and annotations covering safety, the description's enumeration of returned metrics is the key missing piece and it supplies it. It is nearly complete, only lacking any note on result ordering or per-tech grouping behavior.

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 defaults documented in the schema itself, so the baseline is 3. The description only restates the optional technician filter and adds no syntax or format detail beyond the 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?

States a specific verb+resource (per-technician performance) and enumerates the outputs (jobs scheduled, completed, completion rate) over a date range. This is clearly distinguishable from generic list tools, though it does not explicitly contrast with close siblings such as tech_workload or technician_jobs.

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 phrase 'Optionally restrict to one technician' gives a usable condition for the technician_id parameter, but there is no explicit when-to-use guidance relative to sibling performance/workload tools and no exclusions. Usage is implied rather than stated.

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