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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The one behavioural addition is that market/kind get recorded into the link's tracking tags, which is genuinely useful, but nothing is said about what the returned onboarding content looks like or any access constraints.

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?

It is a single dense sentence, front-loaded with the audience condition before the content list, and the tracking-tag note is appended last. No filler, though the colon-list construction is a touch run-on.

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 read-only info tool with no output schema, the description usefully enumerates the returned topics (shop mechanics, payouts, availability, sign-up link) and explains the input side-effect. It is complete enough to call correctly, though it omits any mention of the closed-world/local scope.

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%, so both parameters are already documented, and the baseline is 3. The description adds only that market/kind land in the tracking tags of the generated link, a small but real increment over the schema's field descriptions.

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?

The description states exactly what content is returned: how a Fleek creator shop works, how payouts work, where shops are open, and the sign-up link. It implicitly distinguishes from the merchant_onboarding sibling by scoping to 'an individual with an audience', but never names the verb 'get'/'retrieve' explicitly, leaving the action slightly implied.

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 a clear target user ('an individual with an audience who wants to sell subscriptions'), which lets an agent route creator questions here. However, it never names alternatives such as merchant_onboarding or states when this tool should NOT be used, so the routing guidance 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.
