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

With no annotations, the description carries the full burden, and it does so thoroughly. It discloses that the tool is PAID, that it returns a recipe rather than directly modifying files, that certain marked files must be copied verbatim and never rewritten, and that a share code is required. This is strong behavioral disclosure well beyond a generic 'emit an app' phrase.

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?

The description is dense but every sentence earns its place: cost signal, core purpose, return format, critical handling instructions, and prerequisite. It is front-loaded with the most decision-relevant fact (PAID) and avoids filler.

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?

The description is largely complete for a tool with no output schema: it explains what will be returned, what to do with returned files, and what input is needed. It doesn't cover error cases or what happens on invalid share codes, but for selecting and invoking the tool, the essential context is present.

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%, so the schema already documents appId and override well. The description reinforces that appId is the share code from the composer, matching the schema description, but it adds no substantially new parameter-level meaning. Baseline 3 is appropriate.

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 and resource: 'Turn a recipebooq canvas into a working app' with concrete outputs like navigation, providers, tab bar, screens, and components. It also explains what the tool returns (a recipe with files, paths, dependency install line, and ordered steps), which clearly distinguishes it from the sibling get/list/check tools.

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?

The description gives a clear trigger context: use this when a canvas should become a working app, and it states the required prerequisite (the composer's share code). It doesn't explicitly name alternatives or say when not to use it, but the tool's purpose is so distinct from the sibling inspection tools that the usage context is effectively clear.

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