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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds useful pagination behavior (20 items per page, hasMore/page continuation) and newest-first ordering, going beyond the structured safety hints.

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 sentences are front-loaded with purpose and pagination mechanics, with no filler. The sentence about filters being listed by botclaw_get_catalog is slightly indirect but still earns its place by pointing to discovery.

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 an output schema present, return values need not be explained. However, for a six-parameter tool with 0% schema coverage, the description leaves several filter parameters opaque, though it does direct the agent to botclaw_get_catalog for their values.

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%, so the description must compensate. It explains content_type (default news and alternatives) and page continuation, but leaves product, category, language, and selected unexplained, failing to cover most of the six parameters.

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 verb and resource: 'Read the latest dated agent news, newest first,' making the scope clear. It does not explicitly differentiate itself from siblings like botclaw_get_daily or botclaw_search, but the 'latest' and ordering cue are reasonably distinct.

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?

Gives implied usage guidance by naming content_type alternatives (guide, experience, review) and pointing to botclaw_get_catalog for filters. However, it does not state when to prefer this tool over siblings such as botclaw_search or botclaw_get_daily.

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