panelica_php_get_v1_php_versions

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds one genuinely useful piece of context beyond annotations: "Required scopes: domains:read", which an agent needs to know before calling. The "Read-only" line is redundant with annotations but consistent, and no contradiction exists.

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 five short lines, each earning its place: the action, the endpoint, the category, the required scope, and the read-only flag. It is front-loaded with the core purpose and contains zero filler or repetition.

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 parameterless, read-only list operation with annotations covering the safety profile and the description providing the auth scope, little is missing. The only gap is clarifying its relationship to the Laravel-specific PHP versions endpoint, which is a minor omission given the tool's simplicity.

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 has zero parameters and an empty input schema, so the baseline is 4. There is nothing for the description to explain about parameters; it correctly remains silent.

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 states a specific verb and resource: "List PHP versions" is unambiguous, and the HTTP endpoint GET /v1/php/versions reinforces the target. It is distinct from the closest sibling panelica_laravel_apps_get_v1_laravel_php_versions by naming the generic PHP endpoint, though it does not explicitly call out that distinction.

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 when-to-use or when-not-to-use guidance is provided. The endpoint path and Category: PHP tag imply context, but the description never tells the agent to prefer this over the Laravel-specific PHP versions sibling or explains the difference between them.

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