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

Annotations already cover readOnly=false, idempotent=true, destructive=true, openWorld=true, so the bar is lower. The description still adds real value: it discloses that activation is recurring, consumes 'credit caps', and that previously approved automatic delivery can publish to connected channels — a genuine side effect beyond the safety flags.

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 core action and followed by scope constraints. No filler, though the middle sentence about automatic delivery is slightly disconnected in flow.

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, so return values need not be described, but the four required parameters are fully undocumented at 0% coverage in both schema and prose. For a destructive, state-changing activation tool this leaves a noticeable gap.

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 description coverage is 0% and the description never explains brandId, automationId, revision, or idempotencyKey. It vaguely alludes to a 'saved recipe'/'saved automation type' (automationId) but adds no format, revision-checking, or idempotency semantics, so it fails to compensate for the documentation gap.

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 ('Activate') and resource ('recurring generation using the saved recipe and credit caps'), and scopes it via 'Only enhanced product images; the saved automation type must match this tool.' This differentiates it from the product_staging or retouch siblings, though it never names a sibling 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?

The 'saved automation type must match this tool' line implies this is the correct tool only for product-beautifier automations, and 'Previously approved automatic delivery' hints at an approval prerequisite. However, it gives no explicit when-to-use vs. resume_/pause_/update_product_beautifier_automation guidance.

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