cf_firewall_events

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It merely restates that the tool fetches events and adds no context about pagination, date/time semantics, limits, rate restrictions, or possible failure modes.

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 with no filler and leads with the verb and resource. It is concise, though the brevity comes at the cost of helpful detail.

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 five parameters, no output schema, and no annotations, the description is too sparse. The optional filters 'since', 'until', 'limit', and 'action' are left ambiguous, so an agent cannot confidently construct a correct call beyond providing a zoneId.

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 20%, with only zoneId explained. The description does not define 'since', 'until', 'limit', or the intended meaning of 'action' despite the enum, so it fails to compensate 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 identifies a specific action (Gets) and resource (firewall events for a Cloudflare zone), which is enough to distinguish it from unrelated siblings like cf_list_dns_records or cf_purge_cache. However, it does not explicitly contrast it with partially overlapping tools like cf_get_analytics.

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?

There is no guidance about when to use this tool versus alternatives, nor any stated exclusions or prerequisites beyond the implied need for a zone. The description only conveys the resource type, leaving selection entirely to inference.

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