ga4_update_property

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

With no annotations, the description carries the full burden of behavioral disclosure. It does state the partial-update behavior ('Only the fields you pass are changed'), which is useful. However, it omits crucial behaviors: the 'confirm' parameter is not explained (likely a confirmation flag for mutation), there is no mention of permissions, response format, or idempotency. For a mutating operation, this is insufficient.

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 extremely concise: two sentences with no filler. The primary purpose is front-loaded in the first sentence, and the critical partial-update behavior is clearly stated second. Every word 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?

Given no annotations and an output schema (not shown), the description still lacks crucial context: the 'confirm' field's purpose, the exact format for each field, and any prerequisites (e.g., required permissions or property ownership). An agent cannot safely call this tool correctly without additional knowledge, especially for a mutation that may have side effects.

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%, so the description must compensate for parameter meaning. It lists the field names (display_name, time_zone, currency_code, industry_category), which aligns with the schema's property names, but adds no format guidance (e.g., time zone format, currency code standard, industry category options). The 'confirm' parameter is entirely unexplained. The description adds only marginal value over the schema's property keys.

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') and the specific resource type ('GA4 property') along with exactly which fields it affects (display name, time zone, currency, industry). This distinguishes it from sibling tools like ga4_update_data_stream and ga4_create_property without needing to inspect the schema.

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 implies usage by listing updatable fields, but it does not explicitly say when to use this tool over alternatives (e.g., when you need to modify property-level settings rather than data streams) or mention any exclusions. The lack of comparison to ga4_get_property or ga4_create_property leaves the agent to infer context.

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