Ga4.Admin.List Key Events

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

No annotations are supplied, so the description carries the full burden and does not state that this is a read-only operation, whether results are paginated, or what access/permissions a property requires. The only added context is the 'key events = conversions' gloss.

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?

One front-loaded sentence with no filler. It is efficient, though the brevity borders on under-specification rather than tightness.

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 one-parameter list tool with an output schema that covers return values, the description is minimally adequate. It leaves the agent without pagination behavior, identifier format, or read-only confirmation.

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% for the single parameter, but the phrase 'under a GA4 property' establishes that property_id identifies the GA4 property, which is the main semantic an agent needs. It still omits the expected identifier format (numeric vs 'properties/NNN').

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?

Specific verb (List) plus resource (key events) and a scope (under a GA4 property), with the useful parenthetical that these are conversions. It is clearly distinct from ga4.admin.create_key_event by the verb, though the description itself does not name the sibling.

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?

No statement of when to use this versus the reporting tools (ga4.report) or create_key_event; the agent must infer that this is for enumerating existing conversion definitions. No prerequisites or exclusions are given.

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