getTolkCompilerVersion

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

No annotations are provided, so the description must carry the full behavioral burden. It does indicate this is a read-only operation by saying 'Returns,' and it implies no side effects, but it does not disclose the return format (e.g., whether it is a string, semver, or includes build metadata).

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 two short sentences with no redundant detail. The core behavior is front-loaded, and the usage hint is appended efficiently without wasting tokens.

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?

Given the tool's low complexity, zero parameters, and simple return purpose, the description covers the essential invocation context. The only slight gap is that with no output schema, the exact return type/format is not specified, but this is not critical for calling the tool correctly.

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 and the schema coverage is 100%, so there are no parameter semantics to explain. Per the calibration, zero-parameter tools receive a baseline of 4, and the description correctly focuses on the return value instead.

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 uses the specific verb 'Returns' and names the exact resource—'the current version of the Tolk compiler.' It is clearly distinguishable from sibling runTolkCompiler, which presumably executes compilation rather than reporting version information.

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?

The statement 'Use this to check compiler compatibility' gives a clear, concrete use case for the tool. However, it does not explicitly mention the alternative sibling tool or state when not to use this tool, so there is no exclusion guidance.

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