cdn_get_cdn_zone_logs

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

With no annotations, the description carries the full burden. It does disclose the flexible identifier resolution behavior and states the return value ('CDN zone access logs with request details'), but it omits other behavioral details such as whether logs are delayed, any rate limits, date-range constraints, or timezone handling.

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 well-organized with a one-line purpose, a helpful resolution note, and a clean Args/Returns layout. It is concise, though 'use origin domain, CDN domain, or UUID' is partly redundant with the zone_identifier parameter description.

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 simple read-only log retrieval tool with one required parameter and an output schema, the description covers the essential parameter semantics. It is less complete on usage differentiation, optionality of dates, and edge-case behavior, but it does not leave an agent without enough to make a reasonable call.

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, and it does. It explains that zone_identifier accepts 'origin domain, CDN domain, or ID', specifies ISO date formats, and clarifies per_page as 'Number of items per page (default: 25)'.

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 and resource: 'Get access logs for a CDN zone.' This is specific enough to distinguish it from most tools, though it does not explicitly contrast it with related siblings like cdn_get_cdn_zone_stats or cdn_get_cdn_zone_summary.

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 tool's intended use is implied by its name and opening line, and the 'Smart identifier resolution' note gives useful context for identifying the zone. However, there is no explicit guidance on when to choose this tool over sibling CDN tools or what conditions make it inappropriate.

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