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

No annotations are provided, so the description must carry the burden. It discloses that the tool returns title, description, and URL, and instructs to always reference the URL in responses. However, it does not mention pagination, sorting, or any side effects (likely read-only). Adequate but lacks depth.

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?

The description is a single sentence but covers the main action, scope, and output. It could be more concise by separating the behavioral instruction, but it is not overly verbose. The front-loading is adequate.

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?

Given the tool's simplicity (one parameter, no output schema, no nested objects), the description is complete: it explains what is searched, what fields are returned, and how to use the results. No missing critical information.

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% because the only parameter 'query' has a description. The tool description adds minimal value beyond the schema, stating 'from search query' which is obvious. 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 clearly states the tool searches for articles written by the CODENIVERSE team, specifies the topics (AI agent, automation, etc.), and explains it returns title, description, and URL. It distinguishes from siblings like get_article (retrieves a single article) and search_faq (searches FAQ).

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 usage for searching team articles but does not explicitly state when to use this tool versus alternatives (e.g., when to use get_article instead). No exclusions or prerequisites are mentioned.

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