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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, so the safety profile is largely covered. The description adds real value by promising preservation of 2-step carts and 1-click upsells, which is exactly the kind of collateral damage an agent would worry about on a layout mutation. It stops short of saying what does get overwritten or whether a bad sync can be rolled back.

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?

Two short sentences, front-loaded with the verb and resource, followed by a compact example. Nothing is wasted and the reader hits the important preservation caveat immediately.

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 mutating tool with full annotation coverage and fully documented parameters, it is close to sufficient. Missing is what the sync target/source of truth is, what the operation returns or how progress is reported (no output schema), and behavior on conflicting existing layout changes.

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 100%, so the baseline is 3, but the embedded example call demonstrates a concrete, practical parameter combination (locationId + funnelId + dryRun=true). That illustrates the recommended preview-first usage pattern in a way the schema alone does not.

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 (synchronize) and resource (HighLevel funnel step layout), plus a notable preservation guarantee for 2-step carts and 1-click upsells. Siblings are all agency/audit tools, so no differentiation is needed, but the description never says what the layout is synced *from* (template, location default, another step).

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 only usage signal is an example invocation with dryRun=true, which hints at a preview-first pattern. There is no explicit statement of when this tool applies versus doing nothing, no prerequisites (e.g. funnel must already exist), and no exclusions.

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