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

With no annotations, the description carries the full burden, and it usefully discloses the data sources (Google News RSS + HackerNews Algolia), the paid cost model (0.01 USDC via x402), and that results are token-pruned. However, it omits auth requirements, rate limits, result limits, and error/failure behavior, leaving meaningful gaps.

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?

It is a single front-loaded sentence, but a notable share of it is marketing filler ('Zero-Bloat', 'zero ad bloat') that repeats the same claim twice, slightly diluting the useful signal about sources and cost.

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 simple one-parameter search tool with no output schema, the description covers the key facts an agent needs: what it searches, where results come from, that it costs USDC via x402, and that returns are clean/pruned. Only result format and volume details are left unspecified.

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 single 'query' parameter is already documented as a search query for live news, technical articles, and web results. The description adds no syntax, format, or operator guidance beyond the schema, so the baseline 3 is appropriate.

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 states a specific action (executes live Google News RSS + HackerNews Algolia search queries) and the nature of the output (clean, token-pruned results). It distinguishes itself from generic siblings like distill_webpage or recon_webpage_skeleton by specifying live web/tech-news grounding, though it does not name any sibling directly.

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?

Usage context is implied by 'Live Web Search & Tech News Grounding,' suggesting it is for current news/tech lookups, but there is no explicit when-to-use, when-not-to-use, or routing to alternatives like distill_webpage or fetch_arxiv_research_digest.

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