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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful context beyond that: the anchor lines are generated by Claude from the headlines, and coverage spans all radars, telling the agent the content is synthesized rather than raw data.

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 front-loaded sentence that leads with the resource and then qualifies the content; no filler. It is slightly dense with parenthetical-style detail but every clause carries information.

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?

For a zero-required-parameter read tool with no output schema and full schema coverage, the description covers what the tool returns and who authors the content. The shape of the returned broadcast (per-radar grouping, line counts) is left unstated, but nothing needed to invoke it correctly is missing.

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 100% and the single lang parameter is a fully enumerated field with a documented default, so the schema carries the load. The description names the three languages in prose but adds no format or behavior detail (e.g. fallback when a language is unavailable) beyond the enum.

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?

States a specific resource — the current Orb Studio broadcast — and describes its content (top headlines across all radars plus short anchor lines), which distinguishes it from sibling radar tools like get_radars and get_radar. The retrieval verb is only implied by the name, but an agent can tell what it 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.

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

No explicit when-to-use guidance and no named alternatives; the word 'Current' hints at a snapshot of the latest edition but never says whether to prefer this over get_radars or get_radar for headline retrieval. The agent must infer the routing decision.

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