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

Annotations already indicate this is read-only and non-destructive. The description adds meaningful context by promising not to expose coaching notes or private contact fields, which is a useful privacy behavior beyond the annotation. 'Bounded' also hints at limited scope, though the exact bound is not detailed.

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?

A single sentence that front-loads the action and resource, then adds the key privacy qualifier. There is no filler, repetition, or extraneous detail; each part earns its place.

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?

For a low-complexity read tool with zero required parameters and a fully covered schema, the description covers the essential scope and privacy boundary. It could be slightly richer by clarifying what 'coaching signals' includes, but nothing critical is missing for an agent to call 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 100%, so both `limit` and `technician_id` are already documented in the input schema. The description does not need to add parameter-level detail, and it does not meaningfully go beyond the schema. Baseline 3 applies.

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 opens with a specific verb ('Reads') and names a concrete resource: bounded technician performance and coaching signals for the authenticated workspace. It also differentiates itself by stating what it excludes (coaching notes, private contact fields), making its scope clear relative to sibling tools.

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 implies the tool is appropriate when an agent needs technician performance or coaching signals within the authenticated workspace. However, it does not explicitly say when to prefer this over a sibling tool or when not to use it, leaving some inference to the agent.

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