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

Annotations already cover read-only, idempotent, non-destructive, and closed-world behavior. The description adds substantial operational context beyond that: hourly updates from 08:00 to midnight Bucharest time, a fallback before 08:00 returning last night's stories, Romanian-language output, and that each story includes every outlet's headline and link.

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 dense sentence but is front-loaded with the core purpose and every clause carries useful information. It could be slightly easier to scan with sentence breaks, but there is no filler.

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?

With no output schema and a simple one-parameter interface, the description fully explains what the tool returns, how results are ordered, update timing, fallback behavior, language, and included fields. Nothing essential for calling it correctly 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 coverage is 100% and the single limit parameter is fully documented in the schema. The description does not add any meaning beyond the schema, so the baseline of 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?

States a specific resource (today's main news stories in Romania), source (Agregator.ro), inclusion criterion (covered by at least two Romanian outlets), and ordering (most important first). This clearly distinguishes it from the financial sibling tools credite, curs_bnr, and dobanzi_depozite.

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 makes the tool's context clear — today's Romanian news — but does not explicitly say when to use it versus alternatives or provide exclusions. Usage is implied by the content description rather than guided.

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