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

Annotations already establish the mutation profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false). The description adds genuine behavioral content beyond them: the operation is atomic and it returns live CRUD URLs, curl snippets, and contract links, which is important since no output schema exists. It still omits what happens on partial failure or whether repeated calls are safe.

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?

Two sentences with no filler. The scope (what gets scaffolded) is front-loaded and the return artifacts follow, so an agent gets the essentials on the first read.

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 mutation tool with no output schema, the description usefully covers the return payload and the atomic semantics. It is slightly thin on failure behavior and on how it relates to the granular create_* siblings an agent could otherwise call, leaving a small gap for such a large, all-in-one operation.

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 each parameter is well documented with examples, so the schema carries the parameter burden. The description only restates the content categories (resources, typed fields, seed records, endpoints) without adding format, constraints, or interaction rules, matching the baseline of 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?

Specific verb ('scaffold') plus a precise resource ('entire relational domain backend') and an enumeration of what it creates (resources, typed fields, seed records, endpoints). The 'atomically... in a single call' framing implicitly distinguishes it from the granular create_resource/create_endpoint siblings, though it never names them.

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?

No explicit when-to-use or when-not-to-use guidance. The atomic/single-call phrasing hints that this is the bulk alternative to create_resource and create_endpoint, but the description never routes the agent between them or states prerequisites such as needing an existing workspace.

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