explain_label

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

With no annotations provided, the description carries the full disclosure burden. It does state 'Read-only', which usefully signals a safe non-mutating operation, but it says nothing about how it behaves when the label is absent, what 'drift' refers to, or any error outcomes.

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 short sentences with the core action front-loaded and zero padding; 'Read-only' is a clipped fragment but semantically efficient. Appropriately sized for a simple list operation.

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 two-param read tool with no annotations and no output schema, the description is minimally adequate: it explains the action and lists paths. However, it never defines 'drift', gives no sense of the returned list's structure, and leaves one parameter unaddressed.

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 coverage is 50%: 'repo' is documented in the schema, but 'label' has no schema description. The description partially compensates by clarifying 'label' as a 'version label', adding meaning beyond the schema, but 'repo' receives no additional context.

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 and resource: list the differing paths under a version label. This is clear enough to act on, but it does not differentiate itself from the sibling 'compare' tool, which likely also surfaces differences, leaving the agent to infer which is appropriate.

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 condition selecting this over alternatives like 'compare' or 'check_versions', and no prerequisites stated. The only guidance-like content is 'Read-only', which is a safety trait rather than usage direction.

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