Cache status

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

No annotations are present, so the description must carry the behavioral burden. 'Report' signals a read-only operation and 'how fresh' indicates the output is a freshness assessment rather than a mutation. However, it does not define what 'fresh' means (e.g., timestamp threshold) or state that it never triggers a refresh.

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?

A single sentence in active voice with the key concept 'how fresh' front and center. There is no filler, no restatement of the title, and every word earns its place.

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?

For a parameterless tool the description is adequate, but with no output schema or annotations it leaves the exact response shape (timestamp? age? fresh/stale flag?) and freshness criteria undefined. A brief note on what the result provides would make it complete.

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 tool has zero parameters, so the 100% schema coverage is trivially complete and there is no parameter burden for the description to carry. The description adds no parameter semantics, but none are needed.

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 names a specific verb ('Report') and resource ('this server's cached library snapshot'), and 'how fresh' makes it unambiguous that this is a status/read operation. It does not explicitly contrast it with steam_cache_refresh or steam_cache_clear, but the wording is enough to distinguish it from them.

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 on when to call this tool instead of steam_cache_refresh or steam_cache_clear, or what to do if the snapshot is stale. The purpose implies it is for checking freshness, but that is left to inference rather than stated.

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