get_build_prompt

Read-only

Generate a complete, builder-ready PRD and implementation guide for turning one of your ideas into a working app with a specific AI coding tool. Returns the same enriched prompt as the in-app builder workspace, tailored to the chosen builder. Supported builders: lovable, replit, bolt, v0, cursor, base44, deepagent, claude-code, windsurf, tempo, cline, devin, rork, mistral-vibe. Read-only and free; copy the output straight into the target builder.

A4/5.0

Behavior4/5

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

The description adds value beyond annotations: it confirms read-only (consistent with readOnlyHint: true), states it's free, lists supported builders, and clarifies that the output matches the in-app builder workspace. Annotations already cover the safety profile, so this additional context is useful.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences (about 50 words), front-loaded with the main action, and includes all key information: purpose, output equivalence, supported builders, and safety/cost. No wasted or redundant words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 3 parameters, annotations, and an output schema, the description covers purpose, output, supported builders, and read-only nature. It does not mention prerequisites (e.g., idea must exist) or error handling, but these are minor gaps for a tool with a clear read-only profile.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% – each parameter has a description. The tool description repeats the list of supported builders already in the builderId parameter description, but does not add new semantic meaning beyond the schema. Baseline 3 is appropriate when schema already documents parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool generates a 'complete, builder-ready PRD and implementation guide' for turning ideas into apps with a specific AI coding tool. It specifies the verb 'Generate' and the resource 'PRD and implementation guide', and distinguishes itself from sibling tools like get_idea_summary or get_investment_memo by focusing on builder output.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context: when you want a prompt for a builder tool. It mentions supported builders and that it's read-only and free. However, it does not explicitly state when not to use this tool or compare it to alternatives (e.g., other get_* tools that produce different outputs).

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