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

With no annotations, the description carries the full burden. It discloses that lunar festival/tithi dates are approximate and that date fields are ISO. It explains the aggregated nature of the return, though it does not detail auth or rate limits, which are assumed non-intensive. Overall sufficient for a read-only aggregation tool.

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 concise, front-loading the purpose in the first sentence and adding essential details without fluff. 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 tool returns a complex aggregated feed and an output schema exists, the description adequately covers the return structure. It lacks detail on the 'culture/immigration nugget' and 'trending community questions,' but the schema likely fills that gap. Overall complete for the context.

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 0%, so the description must compensate. It explains the `languages` parameter format and indicates `city` and `languages` are optional, but it omits `state` entirely. This partial coverage justifies a mid-range score.

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's purpose as a consolidated daily briefing about Indian America, listing specific components like festivals, events, movies, places, a cultural nugget, and community questions. It distinguishes itself from sibling tools that focus on individual topics.

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 positions the tool as 'Great for a daily briefing,' implying its use for a broad overview. It does not explicitly state when not to use it or name alternatives, but the purpose is clear enough for an agent to differentiate from more specific siblings.

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