Pollar News

Get a Pollar news event

get_event
Read-only

Fetches the full Pollar coverage of a single event by its slug (get slugs from search_news or list_top_news). Returns title, lead, full summary, source citations, mentioned people, locations, charts, links to the same story in other languages, and a canonical pollar.news url. When explainer is set, get_explainer returns a narrated walk-through of the story; when film is set, get_film returns the film's transcript.

  6. First observed

TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description usefully enumerates the payload (title, lead, summary, citations, people, locations, charts, language variants, canonical URL), but much of that duplicates the output schema rather than adding new behavioral context such as caching, rate limits, or errors on bad slugs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action and slug source, then the payload, then related-tool routing. The long return-value enumeration is slightly list-heavy but every clause maps to a real field group.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema and safety annotations already present, the description supplies exactly what those lack: how to obtain the required slug, what the payload conceptually contains, and which sibling handles explainer/film variants. Only the undefined locale parameter remains unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%: slug is documented, but locale (enum, default 'en') carries no description in either schema or description. The description adds the useful hint that slugs are per-locale only indirectly, and never explains the locale parameter's effect. Marginal value over the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Fetches the full Pollar coverage of a single event by its slug') and immediately distinguishes itself from list/search siblings by naming where slugs come from. An agent can tell what this returns without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: slugs come from search_news or list_top_news, and it names the conditional alternatives get_explainer and get_film when the event carries those forms. No explicit 'when not to use', but the context is clear and actionable.

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