ga4_update_property

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

No annotations provided, so the description bears full responsibility. It indicates a write operation and lists updatable fields, but it does not disclose whether updates are partial (patch) or replacement, or any side effects, rate limits, or authorization details beyond the environment variable.

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 a single sentence plus a requirement note, with no wasted words. It front-loads the action and resource, making it easy to scan.

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 7 parameters, 2 required, no output schema, and no annotations, the description covers key updatable fields and the requirement flag but lacks details on other parameters like updateMask, return values, or error handling. It is adequate but has notable 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 description coverage is only 14% (only property has a description). The description adds meaning by listing the updatable fields (displayName, timeZone, currencyCode, industryCategory) but does not cover all parameters (e.g., updateMask). It partially compensates for the low schema coverage.

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 clearly states the action (Update), the resource (GA4 property), and lists specific updatable fields (displayName, timeZone, currencyCode, industryCategory). The [GA4 WRITE] prefix distinguishes it as a write operation among many read tools.

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?

The description mentions prerequisites (GA4_MCP_ENABLE_WRITES=true and confirm=true) which gives context, but it does not explicitly state when to use this tool versus alternatives like ga4_update_account or when not to use it.

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