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

No annotations are present, so the description carries full responsibility for behavioral disclosure. It adequately covers what an agent needs to understand the tool's behavior: the seven-day time window, the order/ranking, the per-force event limit, and the included fields (date, impact, links). The verb 'Get' clearly marks it as read-only, and no side effects, auth, or rate-limit issues are implied. This goes beyond a bare summary but doesn't explicitly confirm safety semantics.

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?

A single sentence packs substantial detail without repetition or fluff. It front-loads the core action and resource, then elaborates on output contents and the optional filter. It could be split into two sentences for readability, but the density is justified by the need to explain a multi-part response with no output schema.

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 tool with one optional parameter, no annotations, and no output schema, the description is complete: it names the data period, the ordering, the per-force limit, the returned fields, and the optional filter. It handles the main ambiguity (what happens with no filter) via the word 'Optionally' and is sufficient for an agent to call it correctly without additional 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 coverage is 100% and the parameter description already states it is optional and lists valid force ids via enum. The description adds meaning by explicitly connecting the parameter to filtering behavior ('Optionally filter to one force'), which the schema alone does not state. This elevates it above the baseline 3 for covered schemas.

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 opens with a specific verb and resource ('Get the last seven days of ranked Blast Radius news') and details the exact output: the Top Headlines strip in order, up to five leading events per force, and per-event attributes. This clearly distinguishes it from siblings like get_force_reading or get_latest_update, which serve different data needs.

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 implies when to use the tool (to retrieve the Top Headlines news strip) and notes the optional force filter, but it never explicitly contrasts with alternatives such as ask_blast_radius or get_latest_update. No direct when-to-use/when-not-to-use guidance is provided, leaving the agent to infer appropriateness from the resource name and output description.

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