opnsense_acme_add_challenge

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

No annotations exist, so description must disclose behavior. It states it adds a configuration but does not clarify that changes are not active until apply, though the instruction to run apply implies this. Lacks details on permission requirements or side effects.

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?

Two sentences, front-loaded with purpose, followed by a crucial usage tip and next step. No wasted words; every sentence is informative.

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 an add tool with a rich schema, the description covers core behavior and key guidance. Absence of output schema is acceptable for a create operation; the follow-up action is mentioned. Could mention that it is not immediately active, but the apply instruction suffices.

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?

Input schema has 100% coverage with descriptions for all 9 parameters. The description adds value by highlighting the Cloudflare-specific parameter usage, reducing ambiguity over which fields to use.

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 tool adds a DNS-01 challenge configuration for certificate validation, distinguishing it from sibling tools like delete/update challenge. It specifies the resource and action unambiguously.

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?

Provides guidance to use dedicated dns_cf_* fields for Cloudflare instead of dns_environment, and mentions the follow-up `opnsense_acme_apply`. Does not explicitly exclude other providers but context is clear.

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