Create cache

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

Annotations indicate this is a write operation (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds no behavioral details beyond that, such as whether duplicate names cause errors, whether creation is immediate or asynchronous, or any cost implications. It does not contradict annotations.

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 extremely concise (one sentence of four words), which is efficient and front-loaded. However, it could be slightly more informative without becoming verbose, such as indicating the cache type or that it creates a managed resource. The brevity risks under-specification.

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?

Given the tool creates a cloud resource, the description omits important context like organizational scope (e.g., which organization or project the cache belongs to), potential cost implications, and the fact that it requires prior configuration like `laravel_cloud_list_regions` for valid regions. The schema covers parameters well, but the high-level context is missing, making it incomplete for a complex operation.

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 each parameter having a clear description (e.g., 'Cache name.' for name, and enums with size details). The tool description adds no additional semantic value beyond the schema, so baseline 3 is appropriate. It does not compensate for any missing schema details.

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 'Create a new cache,' which clearly indicates the action (create) and the resource (cache). It distinguishes from sibling tools like `laravel_cloud_list_caches`, `laravel_cloud_get_cache`, etc. However, it lacks specificity about what constitutes a cache in this context (e.g., Laravel Valkey/Redis) but is otherwise clear.

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?

The description provides no guidance on when to create a cache versus alternative actions like updating or listing. It does not mention prerequisites, such as requiring an existing organization or project, nor does it direct users to related tools like `laravel_cloud_list_regions` for choosing a region (though that hint is in the schema). No when-to-use or when-not-to-use information is given.

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