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

Adds behavior beyond the annotations: decisions are logged in review history (audit side effect) and there's a hard validation rule blocking approval of culturally flagged visuals. That validation rule is not derivable from readOnlyHint=false, idempotentHint=true, destructiveHint=false. It doesn't describe what happens to the adaptation's state post-decision, so not a 5.

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?

Three short sentences, front-loaded with the action, followed by the audit consequence and the hard constraint. Every sentence carries information an agent needs.

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 3-parameter mutation with annotations covering the safety profile and no output schema, this is nearly sufficient. Minor gaps remain around what the tool returns and whether an already-decided adaptation can be re-reviewed.

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 schema coverage at 33%, only the note field is documented in the schema, and the description restates its conditional requirement when requesting changes. The decision enum semantics (approved vs changes_requested) are clarified in prose, but adaptation_id gets no explanation of what it identifies or where to obtain it.

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 pair and resource: approve an adaptation or request changes, with the note requirement clarified. It's clearly distinguished from generate_adaptations and list_adaptations by being the decision step, though it doesn't name those siblings explicitly.

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?

Gives a concrete eligibility gate — visuals that failed the cultural risk review cannot be approved — and clarifies the two decision paths. It lacks explicit when-not/alternative routing, but the preconditions are clear enough to act on.

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