get_digest_brief

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

Discloses that it is free, rate-limited at 5/min per IP, requires no wallet/API key, and returns only a title/summary without analysis. Since no annotations exist, this description fully covers the safety/access profile.

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?

Three concise sentences deliver purpose, endpoint, cost, rate limit, and auth requirements without waste. Front-loaded with main purpose.

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-parameter tool with no output schema, the description provides sufficient context: what it returns, what it omits, access constraints, and alternative. Complete for its complexity.

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?

The input schema has zero parameters, so baseline score 4 applies; description adds no parameter details because none exist.

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?

Clearly states the tool returns a teaser with title and summary, explicitly excludes analysis, and identifies the endpoint. Distinguishes from siblings by contrasting with the paid get_digest tool.

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?

Explicitly mentions the alternative get_digest for the full paid digest, and specifies costs, rate limit, and auth-free access, providing clear when-to-use guidance.

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