get_versions

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

No annotations provided, so description covers key behaviors: lists return fields and states response is signature-verified. Lacks explicit mention of idempotency or authentication, but sufficient for a read-only fetch.

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 focused sentences, no redundant information, front-loaded with action and resource.

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 single parameter and no output schema, the description covers return fields, verification, and a use case. Could specify if history is limited (e.g., pagination), but 'full version history' implies completeness.

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 100% with a clear description for agent_handle. The tool description does not add further information about the parameter beyond what the schema provides.

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?

Description clearly states it fetches full version history with specific fields (semver, hashes, timestamps), distinguishing it from sibling tools that handle track records or UTRs. Includes a use case.

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?

Provides useful context: 'useful for understanding which version of an agent's policy produced a given track record.' Does not explicitly exclude other uses or name alternatives, but context is clear.

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