Restart PHP

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

Does not disclose behavioral traits beyond the action itself. No mention of side effects, required permissions, or that it returns an operation_id (which is already stated but minimal). Annotations only have openWorldHint, so description should add more context.

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?

Extremely concise: single sentence that conveys the core action and return value. No wasted words, front-loaded.

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?

Adequate for a simple tool with one parameter and an output schema. However, lacks any mention of when restart is needed, potential risks, or error handling. Could be more complete for a restart action.

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 does not add extra meaning to the environment_id parameter. It correctly implies the parameter is needed but adds no details beyond schema.

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 (restart) and resource (PHP) with scope (for an environment). Distinct from sibling tools like 'kinsta.tools.php-version' which deals with version, not restart.

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 on when to use this tool versus alternatives. Does not mention prerequisites, such as needing an environment ID or that restarting may disrupt service.

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