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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description usefully adds the sort key (source publish date) and direction (newest first), but says nothing about pagination, result caps, or whether the window is a hard cutoff — gaps that matter for a listing endpoint.

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?

Two short sentences with no filler; the ordering rule and the intended use are front-loaded and each sentence earns its place.

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?

For a two-optional-parameter read tool with no output schema, the description conveys the shape of the result (a recency-ordered list) but omits how many items come back and how the days/limit knobs behave. Adequate but with clear gaps.

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 0%: both 'days' and 'limit' have no descriptions, only types/defaults/bounds. The phrase 'this week' loosely maps to the days=7 default, but the description never explains the day-window parameter or what limit does. With low coverage, the description should compensate and largely does not.

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 ('browse') plus the resource (use cases) and adds the ordering semantics ('by source publish date, newest first'), so the agent knows this is a recency-sorted listing. It does not explicitly contrast itself with search_use_cases or use_cases_by_tool, but the browsing framing implicitly separates it from a search tool.

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?

'Use to browse what builders shipped this week' gives a concrete usage context, but there is no statement of when-not-to-use it or which sibling to pick for filtered/lookup queries (get_use_case, search_use_cases, use_cases_by_tool). Usage is implied rather than routed.

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