atlas_data_freshness

Check per-source data freshness for OONI, IODA, CensoredPlanet, and Voidly probes to see when each was last ingested and how stale it is, ensuring data is current before use.

Instructions

Per-source data freshness — when each upstream feed (OONI, IODA, CensoredPlanet, Voidly probes) last ingested and how stale it is. Call to check whether data is current before relying on it.

Behavior4/5

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

With no annotations, the description carries the full burden. It accurately conveys the tool is a read-only status check, listing the feeds and what information is provided (freshness and staleness). No side effects or auth details are needed for this simple tool.

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

Conciseness5/5

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

Two sentences with no wasted words. Every phrase adds value: defines the output, lists sources, and gives usage advice.

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

Completeness5/5

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

Despite having no parameters and no output schema, the description fully covers what the tool does and why to use it. No additional details are needed for this straightforward status checker.

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

Parameters4/5

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

The tool has no parameters, so the description does not need to add parameter details. The schema coverage is 100% (empty), meeting the baseline expectation.

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?

The description clearly states the tool's purpose: to show per-source data freshness for specific upstream feeds (OONI, IODA, etc.). It distinguishes itself from other atlas tools that perform analysis rather than status checks.

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?

The description explicitly advises calling this tool to check data currency before relying on it, providing clear usage context. It does not specify when not to use, but the simplicity of the tool makes that unnecessary.

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