About skgate

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

Annotations already cover readOnly/idempotent/closed-world safety, but the description adds genuinely new context: 'Read-only and offline: it answers from the binary alone and contacts nothing' clarifies there is no network dependency or side effect. It also enumerates the returned fields, though the output schema already documents the shape.

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?

Front-loaded with the verb and scope, followed by argument behavior, return shape, and the routing hint. Three tight sentences with no filler.

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 a zero-param tool with full schema coverage, existing annotations, and an output schema, the description supplies everything else an agent needs: what it answers, that it is offline/read-only, and when to call it relative to siblings.

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?

Zero parameters, so per calibration the baseline is 4. The description confirms 'Takes no arguments', which matches the empty schema and removes any ambiguity about hidden inputs.

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?

States a specific verb+resource ('Describe skgate') and enumerates exactly what it covers: what it is, running version, edition, licence, source and docs locations. An agent can distinguish it from list_features and config_help (both named) without opening any schema.

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 instructs 'Call it first to learn what skgate is before using list_features or config_help', naming both alternatives and the ordering condition that selects this tool. No inference required.

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