cache

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

With no annotations, the description carries the full burden of behavioral disclosure. It names the actions but does not warn that 'clear' is destructive, what 'disable'/'enable' affect, or whether these actions persist across sessions. The word 'Inspect' also downplays the mutating actions.

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 brief and front-loaded with the tool's purpose, followed by a clean parameter list. The only structural issue is the mismatch between 'stats or clear' and the four listed actions.

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 tool is simple and has an output schema, so return-value details are not required. But a cache-control tool that includes a destructive action needs warnings and scope information, which are absent. The description does not fully prepare an agent to invoke the mutating actions safely.

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 provides only a loosely typed optional string with no enum or description, so the description's explicit list of allowed values ('stats' | 'clear' | 'disable' | 'enable') is genuinely useful. However, it does not explain the meaning or side effects of each action value.

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 clear verb ('Inspect') and resource ('response cache') and lists the actions it supports, which separates it from the unrelated sibling tools. However, the first sentence says 'stats or clear' but the Args section includes 'disable' and 'enable', creating a small scope inconsistency.

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?

There is no guidance about when to use this tool, when not to use it, or what problem it solves beyond the obvious. The action names imply possible uses, but the description never explains scenarios like stale cache, troubleshooting, or re-enabling the cache.

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