opnsense_acme_update_challenge

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

With no annotations provided, the description carries full transparency burden. It discloses that the tool performs a write operation and requires a separate apply step to commit changes, but does not mention error handling, permissions, or what happens if the UUID does not exist.

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 concise sentences: first states the action and identifier, second gives usage context and a critical follow-up step. No redundancy, front-loaded with key information.

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?

Covers purpose, usage context, and a necessary post-step. The lack of an output schema is partially mitigated by the clear mutation nature, but missing details about error scenarios or prerequisites (e.g., UUID must exist) prevent a perfect score.

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 baseline is 3. The description adds context by grouping parameters as 'credentials or settings', but does not elaborate beyond what the schema already provides for each parameter.

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?

Clearly states the action ('Update'), the resource ('existing ACME challenge/validation'), and the identifier method ('by UUID'). Mentions what can be changed ('credentials or settings'), and distinguishes from sibling tools like opnsense_acme_add_challenge (create) and opnsense_acme_delete_challenge (delete) by focusing on updates.

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 explicit guidance on when to use ('to change credentials or settings') and a necessary follow-up action ('Run opnsense_acme_apply afterwards'). Implicitly differentiates from add/delete siblings, though it lacks explicit 'when not to use' statements.

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