read_articles_batch

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

With no annotations provided, the description fully carries the transparency burden. It discloses key behaviors: automatic 5-second delay for rate limiting, max 5 articles, failure isolation (single failure doesn't affect others), and expected time duration. It also mentions the return format, making the tool's behavior predictable.

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 well-structured with sections (overview, typical flow, args, returns, example, notes), front-loads the critical constraints (max 5, interval), and every sentence provides useful information without redundancy. It is appropriately sized for the tool's complexity.

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 has only 2 parameters and no annotations, the description is complete: it covers the usage workflow, parameter meanings, return format, a concrete example, and operational notes. The presence of an output schema reduces the need for detailed return explanation, and the description still covers it sufficiently.

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 no descriptions for parameters, but the description explains urls (required, max 5) and timeout (default 30, per-request timeout). This adds crucial semantics beyond the schema, enabling correct parameter usage.

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 it reads multiple articles in batch, with a max of 5 and a 5-second interval. It uses a specific verb and resource ('batch read articles'), distinguishing it from the sibling tool read_article which handles single articles.

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?

It provides a typical usage flow (search_news first, then batch read, then analysis) which gives clear context for when to use this tool. However, it doesn't explicitly state when not to use it (e.g., for a single article, read_article might be preferable), so it lacks explicit exclusions.

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