Game data status

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

readOnlyHint=true already declares this is a non-destructive read, so the safety profile is covered by annotations. The description adds the useful behavioral detail that results include cache location and per-file load/check state, which mild-compensates for the absent output schema, but it says nothing about the shape of the result, whether files are listed exhaustively, or what 'whether it loaded' looks like on failure.

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 tight sentence with no filler, and the most useful content (cache location) is front-loaded. Slightly under-specified rather than over-long, but nothing in it is waste.

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 zero-parameter read-only diagnostic with no output schema, describing the three things returned (location, last-checked time, load status) supplies most of what an agent needs to interpret the result. It could note what constitutes a stale/failed state, but the essentials are present.

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 takes no parameters, which is the baseline-4 case; there is nothing for the description to disambiguate. The description correctly implies the call is unconditional and takes no arguments.

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 the resource (game data cache/status) and enumerates the specific content reported: cache location, per-file last-checked timestamps, and load success. It is clear enough to distinguish from every sibling (which are build/analysis tools), but it is written as a noun phrase describing return content rather than stating the operation, so the 'what it does' verb is implicit (report/inspect status) rather than explicit.

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 when-to-use guidance, no mention of what a stale or failed load implies, and no routing to or away from any sibling tool. The agent must infer that this is a diagnostic call to check data freshness before running build operations.

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