get_recall_precision

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

Annotations already declare readOnlyHint=true. The description goes further by stating it never recalibrates or persists, and details the returned fields (beta, precision level, override flags). This adds behavioral context beyond the annotation, though it doesn't cover all edge cases.

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 a single paragraph that front-loads the main purpose and then provides additional details. It is reasonably concise, though some sentences could be tightened. Every sentence adds value.

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 simple input (1 param, no output schema), the description thoroughly explains the return value and its relationship to the global default and override behavior. It is complete for a read-only tool of this complexity.

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?

The schema covers the single required parameter (agent_id) with a description. The tool description does not add meaning beyond that, but since schema coverage is 100%, a baseline of 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 reads an agent's effective recall precision, identifies it as the read-back companion to set_recall_precision, and specifies it is read-only. This distinguishes it from its sibling and provides a specific verb-resource combination.

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 explains when to use this tool (as a read-back companion to set_recall_precision, for UI loading before editing) and implies it should be used before writing. However, it does not explicitly mention alternatives or when not to use it, though the sibling set tool is clearly the counterpart.

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