refresh_cache

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

The description mentions parallel fetching and cache bypass, which are key traits. But without annotations, it should disclose potential costs (external fetches) and safety (non-destructive but mutates cache). Currently lacks these.

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?

Two sentences with no redundancy. The first sentence states the main action, the second explains the parameter behavior. Efficient and well-structured.

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?

With an output schema and a single optional parameter, the description covers the essential information for invocation. Minor gap: doesn't mention the effect on other tools' data (e.g., get_policy will now show fresh data).

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 only parameter 'keys' has no schema description, but the description clarifies its meaning: omit to refresh all, provide to refresh specific. This adds value beyond the schema.

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 action (re-fetch policy documents via parallel) and resource (ASF website), and it distinguishes from sibling tools that read the cached policies.

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?

It explains when to use the tool (to bypass cache and force refresh) and how to scope the refresh (omit keys for all, provide keys for specific). However, no explicit 'when not to use' or alternatives.

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