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

Adds context beyond annotations: explains the source (English Wikiquote) and locale behavior for non-English 'lang' values. No contradictions with annotations.

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?

Single sentence with no fluff. Key information front-loaded: 'Daily featured quote' with parenthetical detail about locale.

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?

Sufficient given simplicity (1 optional param, read-only, output schema exists). Could mention return format but output schema handles that.

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?

Only parameter 'lang' is not described in schema (0% coverage). Description explains its effect with an example ('lang=fr returns locale equivalent'), adding necessary meaning.

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?

Clearly states it returns a daily featured quote from English Wikiquote with optional language override. Not explicitly differentiating from sibling 'quotes' but the 'daily featured' and locale behavior provide distinction.

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?

Implies usage for fetching a daily quote in a specific locale, but lacks when-not-to-use or comparison to sibling 'quotes'. No alternative suggestions.

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