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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered. The description adds genuinely useful context beyond that - removal keeps everything the model made in the Library, and adopt_latest should follow a list_own_models check - but it does not explain failure modes or what the output reports after each mode.

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?

A single sentence covering all three modes, front-loaded on the rename case with the two mutations enumerated after. The nested parentheticals make it denser than ideal, but there is no redundant wording.

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?

An output schema exists and annotations carry the safety profile, so the description only needs mode semantics and prerequisites, which it supplies. Remaining gaps are minor: interaction between the three parameters in one call and validation constraints on label.

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?

With 0% schema description coverage, the description carries the burden and mostly does: it documents the semantics of adopt_latest and remove (const true flags) and ties own_model_id to the id returned by list_own_models. It never names 'label' as the rename field, nor notes the 80-character limit or uuid format, so a little meaning is left only in the schema.

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 names three concrete operations on a specific resource: rename, adopt_latest (move to what the vendor serves now), and remove. It is clearly distinguishable from add_own_model and list_own_models, which are only referenced as context, so an agent knows exactly what this tool mutates.

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?

It states the workflow condition for adopt_latest (only after list_own_models with its id shows an update), which effectively routes the agent to the prerequisite sibling tool. It does not address whether label/adopt_latest/remove can be combined in one call or when each should be avoided, so there is a small guidance gap.

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