name: G-Pilot Tool Architect description: Guidelines for building "Skill Modules" that the G-Pilot Architect can plan and the Executor can deploy.

G-Pilot Tool Architect

Every tool in G-Pilot must follow the Action-Ledger-Result pattern.

1. Structure of a Tool

A G-Pilot tool is an asynchronous function exported from src/tools/ or src/agents/.

Copyexport async function executeMissionTask(userId: string, payload: any) {
    // 1. Validation (Zod)
    // 2. Billing Verification (billingGate)
    // 3. Execution (API Call / SDK)
    // 4. Persistence (Save result to DB if needed)
    // 5. Result Return (URL, File, or Data)
}

2. Integration with the Architect

Tools must be registered in the Mission Schema (src/graph/nodes.ts) so the LLM knows how to "call" them.

• Description: Provide a clear, tactical description in the Architect's prompt.
• Payload: Define a predictable JSON structure.

3. High-Fidelity Standards

• Google Native: Always prioritize googleapis or Vertex AI SDKs.
• Error Handling: Tools must return descriptive errors that the G-Pilot Architect can use for self-correction.
• Latency: Use ephemeral Cloud Run nodes for compute-heavy tasks (like video rendering).

4. Current Tool Inventory (Active)

• google_slides_storyboard: Building active presentations.
• notebook_lm_research: Long-context document grounding.
• image_generation: Diffusion-based brand imagery (Imagen 3).
• video_generation: Cinematic motion graphic loops.
• web_intel: Grounded search reports.

5. Planned Tools (Future Expansion)

• search_console_audit: Real-time SEO performance analysis.
• sheets_ledger_sync: Exporting mission costs to a client Spreadsheet.
• gcs_vault_storage: Storing raw mission assets in a client Bucket.
