arvan_update_caching_settings

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

Annotations indicate this is a mutation (readOnlyHint=false) that is not destructive (destructiveHint=false) and not idempotent (idempotentHint=false). The description adds an example of settings structure but does not disclose whether updates are incremental or full replacement, or any side effects. Some value added beyond 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 concise: one short sentence stating the purpose, followed by a brief example. No unnecessary words, and the main action is 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?

The description covers basic purpose and gives an example, but it lacks information about return values, error handling, idempotency, and prerequisites (e.g., domain must exist). It does not differentiate from sibling tools like arvan_purge_cache. Adequate for a simple tool but incomplete.

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 0%, so the description must compensate. It explains that 'settings' accepts caching fields as documented by ArvanCloud and provides an example. However, it does not describe the 'domain' parameter or list specific valid fields. The example provides some guidance but leaves ambiguity.

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 the verb 'Update', the resource 'caching settings', and the scope 'for a domain'. It distinguishes from siblings like arvan_get_caching_settings (read) and arvan_purge_cache (different action). The example further clarifies the action.

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 implies usage for updating caching settings but provides no explicit guidance on when to use this tool versus alternatives (e.g., arvan_get_caching_settings for reading, arvan_purge_cache for clearing cache). No prerequisites or context are mentioned.

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