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

Annotations already declare readOnly=false, openWorld=true, idempotent=false, destructive=false, so the description is not obligated to restate the safety profile. It adds context annotations don't carry: required credential scope and the specific 403 failure mode for unclaimed sandbox workspaces, which is exactly the kind of precondition that prevents wasted calls. It could still note what a repeat sync does to existing catalog data.

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, action first, then parameter provenance, then the two gating requirements. Every sentence carries operational value; nothing is padded.

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 one-parameter, no-output-schema mutation tool, the description covers the action, the argument source, and both hard prerequisites including the exact 403 condition. The only gap is what the caller gets back or how a repeat call affects existing catalog state.

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% and the sole parameter is a UUID with its own description pointing to list_commerce_connectors. The description repeats that same cross-reference without adding format or selection detail, so it neither compensates nor detracts — baseline 3.

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 and resource — pull the catalog from one linked store — and adds the immediacy ('now') that separates it from scheduled syncs. It does not explicitly name the sibling sync_commerce_orders, so the catalog-vs-orders distinction is left to inference.

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 real preconditions (Last Price credential with commerce configure scope, claimed workspace) which effectively tell the agent when the call will fail. However, it never says when to prefer this over sync_commerce_orders or a scheduled pull, so alternative routing is only implied.

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