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

Annotations already declare destructiveHint=true, idempotentHint=true, openWorldHint=true and readOnlyHint=false, so the safety profile is partly covered. The description adds useful context (uses saved recipe and credit caps, approved delivery can publish to connected channels), but it never explains what makes resuming destructive or how the idempotency key affects retries.

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 that are front-loaded, but fragments like 'Only written carousel sections' and 'the saved automation type must match this tool' are cryptic and force interpretation rather than conveying precise meaning.

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?

Annotations and an output schema cover much of the picture, and the description notes publishing behavior and credit caps. However, for a destructive, open-world mutation tool with 0% param documentation and no title, the notable gaps around revision/idempotency semantics and preconditions leave the agent under-informed.

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% for all four required params. The description vaguely gestures at the saved recipe/automation type but does not explain revision (optimistic concurrency) or idempotencyKey (retry safety), which are the two non-obvious parameters an agent must supply correctly.

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 (resume) plus the resource (recurring generation from a saved recipe), and the name anchors it to the carousel creator automation. It is distinguishable from activate_* and pause_automation siblings, though the phrasing 'the saved automation type must match this tool' is workaround-ish rather than plainly saying it resumes this specific automation.

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 gives an implicit precondition ('the saved automation type must match this tool') and hints that previously approved delivery will publish, but never states when to choose resume over activate_/pause_automation or what state the automation must be in. Usage is implied rather than explicit.

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