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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world corpus, so the safety profile is covered. The description adds value beyond them by disclosing the shape of the result (title, description, url) and a hard behavioral requirement that answers must cite the article url — information the annotations do not carry. It omits ranking order and result-count limits.

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 compact clauses: what is searched, what is returned, how to use the result. The scope information is front-loaded and nothing is redundant. It could be tightened slightly, but every sentence earns its place.

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 single-parameter read-only search tool with rich annotations and full schema coverage, the description supplies everything an agent still needs: the corpus boundary, the return fields, and the citation obligation. No output schema exists, yet the return values are described inline, so nothing material 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 'query' parameter already documents that a single word or short phrase works better than a long sentence, including an example. The description only restates 'from a search term', adding no syntax or formatting detail beyond the schema, so the baseline of 3 applies.

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 verb (search) plus resource (articles authored by the CODENIVERSE team) and enumerates the covered topic areas (AI agent, automation, cloud, SEO, digital transformation), which makes the corpus scope unambiguous. It also names the returned fields. It stops short of explicitly contrasting with siblings like search_faq or get_article, so a 4 rather than a 5.

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 is only implied: the reader infers it should be called for keyword lookups over the article corpus, and the closing line mandates citing the article url in the answer. There is no explicit statement of when NOT to use it, nor a pointer to search_faq or get_article as alternatives, leaving routing to inference.

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