refresh

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

Discloses network fetch, cache bypass, and the ability to refresh all libraries. No annotations exist, so description provides necessary behavioral context.

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 zero waste, action verb first, and essential details packed efficiently.

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?

Covers key behavior and parameter usage for a simple tool. Could mention return format or side effects, but sufficient given no output schema and low complexity.

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 has 0% coverage, but description explains the optional 'library' parameter and its default behavior (refresh everything when omitted), adding significant 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 clearly states the action (force-refetch), resource (library's docs), and distinguishes from siblings like get_docs and list_libraries by emphasizing bypassing cache.

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?

Explicitly states when to use (when fresh data needed) and implies when not to (if cached data acceptable). No explicit alternatives named, but context is clear.

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