transition-model-version-stage

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

Without annotations, the description should disclose behavioral traits. It only says 'transition', ignoring side effects like archiving (handled by a parameter), permissions, or impact on other versions. The description does not add value beyond the name.

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 a single sentence with no unnecessary words. It is efficiently short, though it could be expanded with key details without losing conciseness.

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 lack of output schema and annotations, and the tool's moderate complexity (4 parameters, one optional with behavior impact), the description is incomplete. It does not explain return values, failure modes, or the effect of 'archiveExistingVersions', leaving the agent with insufficient guidance.

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% with only the 'stage' parameter having an enum description. The description does not explain any parameters. However, parameter names are self-explanatory (name, version, stage, archiveExistingVersions), so the schema partially compensates. The description adds nothing new.

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 'Transition a model version to a new stage' clearly identifies the verb (transition) and resource (model version stage). It distinguishes from sibling tools like 'update-model-version' which may cover other modifications. However, it lacks specificity about what 'transition' entails (e.g., moving version between stages).

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?

No guidance is provided on when to use this tool versus alternatives like 'update-model-version' or 'set-registered-model-alias'. There is no mention of prerequisites, prohibited transitions, or context for use.

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