panelica_domains_get_v1_domains_id_php

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

Annotations already provide readOnlyHint, idempotentHint, and destructiveHint=false, so the description's 'Read-only' line adds little. It does add the required scope (domains:read) and the explicit HTTP method, which is useful operational context, but it does not disclose return shape or any pagination/list behavior.

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 very compact and front-loaded, with no filler: HTTP method, category, required scope, and read-only status are each on their own line. The opening 'List php' is redundant with the tool title and could be replaced with a clearer noun phrase, which keeps this from a 5.

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 simple read-only, single-parameter GET endpoint, the path, scope, annotation safety profile, and parameter schema together cover most operational needs. However, there is no output schema and the description does not clarify what the returned PHP items represent, leaving some ambiguity about the exact resource being listed.

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 schema already fully documents the sole parameter as a required string path parameter 'id', so description-level parameter explanation is not necessary. The description adds no extra meaning about what kind of id is expected or how it should be formatted; baseline 3 is appropriate given 100% schema coverage.

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 verb and resource ('List php') plus the HTTP path, so it is not a pure tautology. However, 'php' is undefined: it could mean PHP versions, PHP configuration, or installed runtimes for a domain, and it does not distinguish this from sibling tools like the PATCH php endpoint or the global PHP versions listing.

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 about when to use this tool versus alternatives such as panelica_domains_patch_v1_domains_id_php or panelica_php_get_v1_php_versions. The scope and category are stated, but there are no use-case conditions, exclusions, or alternative routing.

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