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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds that the output is tangible ('working code or a ready prompt'), which is useful. However it says nothing about the api_key parameter, any auth requirement, rate limits, or how the openWorld recommendation is bounded.

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?

A single sentence that front-loads the deliverable (recommend products, step-by-step setup, working code) before the qualifying context. It is dense but not padded. Slight reading cost from cramming inputs onto the same line.

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, open-world advisory tool with no output schema, the description conveys the core value. Gaps remain: the role of the api_key, why 'device' matters, and any signal separating this from sebbi_overview or sebbi_gateway_setup are absent.

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 75%, above the threshold where the schema carries most of the load, so baseline is 3. The description reinforces two parameters (stack via 'Python, Node, Lovable, Zapier, a website builder', and goal via 'what they want to achieve') with extra examples, but it does not address device or the api_key parameter, which is entirely undocumented in both schema and description.

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 names a specific verb pair (recommend products + give step-by-step setup) and a concrete resource (sebbi.pro products, working code or a ready prompt). It is clear what the tool produces. It does not explicitly distinguish itself from nearby siblings such as sebbi_overview or sebbi_gateway_setup, so it stops short of a 5.

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?

Usage is implied through the input framing ('how the customer builds... and what they want to achieve'), which tells the agent the context that suits this tool. There is no explicit when-to-use, when-not-to-use, or named alternative to route against, so it remains at an implied level.

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