Get Zone Analytics Tool

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

readOnlyHint=true already declares this as a safe read, so the description only needs to add context. It reinforces the read-only summary nature and adds the zone exclusivity rule, but says nothing about auth requirements, rate limits, or the timezone/aggregation behavior of the date range.

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?

Three tight lines, front-loaded with the purpose, then return contents, then the one invocation caveat. No filler or repetition.

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 an output schema present, the field list is arguably redundant but harmless, and the exclusivity rule covers the main ambiguity. The only remaining gap is guidance on default behavior when no zone is supplied, which is minor given all four parameters are optional and documented.

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 100%, so the baseline is 3, but the description adds a genuine constraint the schema does not express: zone_id and zone_name are mutually exclusive. That is real added meaning beyond the structured fields.

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?

States a specific verb and resource — 'Get zone traffic analytics summary' — and enumerates what the summary contains (requests, visitors, bandwidth, cache ratio, status codes). It is clear what the tool returns, though it never names the sibling analytics tools (get_top_pages_tool, get_traffic_by_country_tool) that an agent might confuse it with.

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 'Provide either zone_id or zone_name, not both' line gives an invocation constraint, which is useful. However, it says nothing about when to pick this tool over the other analytics siblings, or what happens if no zone is supplied (all params are optional and defaulted).

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