ga4_events

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

No annotations are provided, so the description must fully disclose behavior. It does not mention whether the operation is read-only, what the output format is, whether pagination or limits apply, or any side effects. The description says nothing beyond the basic purpose, leaving the agent blind to critical behavioral details.

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 very short at seven words, which is concise, but it under-specifies the tool's purpose. It is front-loaded with the core idea but does not earn its place by adding enough value. It is not verbose, but it is too terse to be helpful.

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?

Given the tool has 4 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain the return value, any filtering semantics beyond event name, or the intended usage. An agent would struggle to call this correctly without external context.

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 75%, with startDate and endDate having format descriptions and property having an example. The description adds no parameter meaning itself. Since coverage is moderate and the remaining parameter (limit) is self-explanatory, the schema carries the burden adequately.

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 'GA4 events by event name' indicates the tool returns events, but it is vague about whether it lists event names, counts, or detailed event data. It does not specify a clear verb like 'get' or 'list', and does not distinguish it from sibling tools like ga4_run_report or ga4_top_pages.

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 guidance on when to use this tool versus alternatives. The description offers no context about typical use cases, prerequisites, or exclusions. An agent would not know why to pick this over ga4_run_report or gsc_search_analytics.

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