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

No annotations are provided, but the description clarifies that min_score is a floor-raiser and items are already editor-scored >=7. It does not mention any side effects or authorization requirements, but the tool appears read-only. Adequate transparency given the tool's nature.

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 well-structured paragraph. It front-loads the main purpose and then details parameters and usage guidance without unnecessary words.

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?

The tool is simple and the description covers usage, parameters, and alternatives. No output schema exists, but the return format is implied. Could mention pagination or response structure, but not critical for this tool.

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 0%, but the description explains each parameter: category lists example slugs, since_days default, min_score meaning, and limit default. This adds significant meaning beyond the schema alone.

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 provides 'newest items on the wire' and specifies the content type as 'freshest judged marketing/growth atoms'. It also distinguishes from sibling tools by directing users to search or topic_pulse for specific topics.

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?

Explicitly states when to use this tool ('what's new / what did I miss / catch me up' with no specific topic) and when not to (for specific topics, use search or topic_pulse).

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