Update CDN firewall settings

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

Annotations already declare readOnlyHint=false and openWorldHint=true, so the '[WRITE]' tag and PATCH method are largely redundant. Beyond the caution about undocumented fields, the description discloses nothing about what settings get overwritten, permission/auth requirements, or the meaning of the opaque 'Offline FA known-bots sample' reference.

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?

It is short and front-loads the write/method info, which is good. But the sentences are fragmented and dominated by unexplained jargon, so brevity comes at the cost of clarity.

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 mutation tool with an open-ended settings object, low schema coverage, and no output schema, the description leaves too much unstated – what the settings fields are, what skip_global_firewall does, and what the PATCH returns or overwrites.

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 coverage is only 33%; settings and skip_global_firewall lack schema descriptions. The description only gestures at skip_global_firewall (via the jargon 'known-bots sample') and adds nothing about the settings object or domain field, so it fails to compensate for the coverage gap.

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 states a specific verb+resource: PATCH /domains/{domain}/firewall/settings, so the agent knows this updates firewall settings. It distinguishes the settings resource from rule-level siblings (create/update_firewall_rule) implicitly through the endpoint. No explicit sibling differentiation beyond that.

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?

'Pass only documented fields' is a constraint, not guidance on when to use this tool versus get_firewall_settings or update_firewall_rule. No prerequisites, no when-not-to-use, no alternative-routing are given.

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