create_haproxy_frontend

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

The annotations indicate readOnlyHint=false and destructiveHint=false, which match the 'Create' action, so there is no contradiction. However, the description adds no behavioral context about side effects, like whether changes require apply_haproxy_changes, impact on existing configurations, or required permissions.

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 concise sentence, but it is almost entirely redundant with the tool name. It is not verbose, yet it under-specifies; a slightly more informative summary would merit a higher score.

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 tool with 9 parameters and related HAProxy management tools, the description is minimal. It does not explain the role of a frontend, how it connects to backends, or when to choose this over other HAProxy tools. The output schema covers return values, but usage context is severely lacking.

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%, with detailed parameter descriptions for bind_addresses, ssloffloadcert, and others. The description itself adds no parameter meaning beyond what the schema already provides, so the baseline score of 3 applies.

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 'Create an HAProxy frontend listener' clearly states the action (create) and resource (HAProxy frontend). It distinguishes from other frontend tools like update/delete/search, though it doesn't elaborate on what a frontend is or provide context for when it should be used.

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?

No guidance is given on when to use this tool versus alternatives such as create_haproxy_backend or update_haproxy_frontend. It does not mention prerequisites, related configuration steps, or when applying changes is necessary.

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