list_events

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

No annotations are provided, so the description carries the full behavioral burden and delivers almost nothing. It does not disclose ordering ('latest' by what field?), whether results are capped or paginated, freshness/refresh behavior, or any auth or scope constraints. The existence of an output schema excuses return-value description, but the operational behavior remains opaque.

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?

A single short sentence with no filler and a front-loaded noun phrase. It is efficient, though the brevity is closer to under-specification than to disciplined conciseness.

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 (one optional integer, output schema present), which lowers the bar, but the description still fails to explain the recency semantics behind 'latest' or how this differs from news_feed. For a list tool with an unlabeled limit parameter, that is a meaningful shortfall.

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?

There is one parameter, limit, with 0% schema description coverage, so the schema contributes no semantics. The description only hints at relevance via 'latest' and says nothing about what limit counts (events, days?) or what the default of 20 means in practice, leaving a real gap for the single knob the caller can turn.

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 phrase 'Latest news events in the store' identifies the resource (news events) and implies a listing/recency behavior, but never states a verb and never distinguishes the tool from the sibling news_feed or analyze_news. An agent can guess it fetches a recent-events list, but cannot tell why it would pick this over news_feed.

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?

There is no when-to-use guidance, no exclusions, and no reference to any alternative. With news_feed and analyze_news in the sibling set, the lack of routing guidance leaves the selection decision entirely to guesswork.

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