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

Annotations only give readOnlyHint and openWorldHint; the description adds that it makes no provider calls and is safe to poll, which is real behavioral context beyond the structured fields. It doesn't detail latency or rate limits, but for a read-only status tool this is strong.

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?

Front-loaded with purpose and return shape, then usage guidance; every sentence earns its place. The trailing '[#01f20c]' artifact is stray noise that slightly detracts.

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?

With no output schema, the description does the work of describing the return payload (readiness flags, per-store breakdown, next_steps). An agent has enough to call and interpret it, though the semantics of each readiness flag aren't spelled out.

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 100% and the single workspace parameter is fully documented in the schema, including the multi-workspace failure mode. The description adds nothing about the parameter, so the baseline 3 applies.

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+resource (check account setup readiness) and enumerates what it returns (ready_to_design / ready_to_fulfill / ready_to_sell, per-store breakdown, ordered next_steps). This distinguishes it from sibling diagnostics like get_account_overview or check_connection_status.

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 when-to-use: 'Start here for any first-time setup, and call it again after each connection to confirm the state actually changed.' No named alternative/exclusion, so it stops short of a 5, but the context is clear.

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