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

Annotations provide only openWorldHint, so the description carries the behavioral burden and does so well: it discloses a non-obvious side effect (auto-heal that performs association + fulfillment sync and retries once), the default state, and the resulting write semantics. These are exactly the hidden behaviors an agent needs before invoking a mutating sync.

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?

Purpose and prerequisite are front-loaded correctly and most sentences earn their place, but the final line is a stray bracketed artifact ('[#32962d]') and the auto-heal clause is dense enough to require re-reading. Minor bloat rather than efficient brevity.

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 5-param, no-output-schema mutation tool, the description covers the risky parts well (prerequisites, auto-heal, draft default), so an agent can call it safely. It is still incomplete on parameter semantics — integration_uuid and workspace are unexplained, and there is no note on what a successful sync returns or how to detect partial success.

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% across 5 parameters. The description compensates partially: it gives meaning to 'state' (defaults to draft, live only on explicit request) and names product_uuid and store_uuid in the prerequisite call signature. However, integration_uuid and workspace are never explained anywhere, leaving two required/optional params undocumented.

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 precise verb and resource ('Sync one product to a sales channel ... as a listing') and even names the concrete channel types (WooCommerce/Shopify/Wix). An agent can immediately distinguish this from sync_to_fulfillment, unsync_from_channel, or set_channel_settings.

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?

Explicit prerequisite ordering (sync_to_fulfillment must run first), the exact failing condition to avoid ('product not associated with store'), an alternative that collapses the pipeline (ship_product), and a usage constraint ('Defaults to DRAFT — only push live when the user explicitly asks'). This is textbook when/when-not/alternative guidance.

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