atlas_timeline

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

No annotations provided, so the description carries full burden. It mentions returning events with permalinks, but does not disclose potential limitations like data freshness, pagination, behavior on invalid country_code, or what happens if no events exist. Minimal behavioral detail.

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?

Two concise sentences that front-load key information (what, for whom, time range, outcome) with no wasted words. Highly 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?

Moderate complexity with 2 params and no output schema. The description explains input meaning and mention of permalinks, but lacks output structure details (e.g., list vs array, sorting, maximum events). Could be more complete given missing output schema.

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 coverage is 100% and both parameters are described in the schema. The description adds context (timeline includes forecasts, incidents) but does not add new meaning to the parameters themselves. Baseline 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 returns a 'unified historical timeline' for a country, specifying event types (forecasts, resolved outcomes, incidents) and that each event has a permalink. It distinguishes from sibling tools by focusing on timeline/historical view.

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?

No explicit guidance on when to use this tool versus alternatives like atlas_search or atlas_digest. The description implies it's for a comprehensive historical view, but lacks specific when-to-use or when-not-to-use instructions.

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