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

No annotations exist, so the description carries the full burden. It states the action ('get') and result ('quote') but does not disclose that this is a network call, whether it is read-only, or any rate-limiting/cost hints. The empty [COST: ] placeholder provides no information. Still, the operation is simple and generally expected to be a junk fetch, so it is not heavily misleading.

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?

One short, direct sentence with no unnecessary words. The [COST: ] placeholder is empty but does not materially detract. The essential information is front-loaded and efficient.

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 minimal complexity (no params, output schema exists), the description is probably sufficient for a competent agent. It misses a tiny bit of nuance: it doesn't mention the quote sources or that it is an external API call, but these are not required for a one-liner tool. The empty [COST: ] is a slight gap but not harmful.

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 input schema defines zero parameters, so the description cannot add parameter meaning. With no parameters at all, the baseline is 4: no investment in parameter documentation is needed.

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?

Description uses a specific verb ('Get') and concrete resource ('random inspirational quote'), unambiguously distinguishing it from sibling quote tools like get_kanye_quote or get_trump_quote. The intent is immediately clear even without inspecting the schema.

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 'random inspirational quote' implies when to use it, but it does not explicitly mention alternatives or any context excluding other quote tools. There is no direct 'use this when...' guidance, leaving some ambiguity among numerous sibling quote-fetching tools.

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