apply_haproxy_changes

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

The description adds that this batches pending changes, but annotations already declare idempotentHint=true and destructiveHint=false. It does not disclose potential side effects like service reload or failure conditions if no changes are pending, which would be useful but is offset by the existing annotation coverage.

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 two sentences, front-loaded with the primary action, and contains no redundant or extraneous information. Every word contributes to understanding the tool's purpose and usage.

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 no parameters and an output schema, this description provides enough context: it clearly defines the action and the exact condition for invoking it. An agent can confidently select and call this tool without ambiguity.

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?

The tool takes zero parameters and schema coverage is 100%, so there is nothing for the description to elaborate. The baseline for 0 params is 4, and the description appropriately omits parameter information.

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 'Apply pending HAProxy configuration changes' with a specific verb (apply) and resource (HAProxy configuration). It also contextualizes the action by referencing apply_immediately=False, distinguishing it from immediate-apply tools in the sibling list like apply_firewall_changes.

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?

It explicitly says 'Use this after making changes with apply_immediately=False to batch-apply them,' providing clear when-to-use guidance. It does not mention alternatives or exclusions, but the trigger condition is actionable.

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