Capture design intent for a new Coherence experiment. Triggers on: "build me a...", "prototype a...", "create an Azure page", "scaffold a...", or any request to build a new Azure portal UI. Do NOT build anything — only capture intent and get user confirmation. Your job is done when intent.json exists and the user has confirmed.
YOUR ONLY GOAL: Create an intent.json and get user confirmation. Do NOT write any code.
You are the first phase of the experiment lifecycle. Your job is to translate the user's natural-language request into a structured intent document via the MCP Design Intent UI, then wait for the user to review and confirm it. You produce zero code files.
If the user's message or the orchestrator's dispatch includes a Figma URL (figma.com/design/ or figma.com/file/), the Figma design will be used as a starting point. The mode determines HOW:
The orchestrator passes the mode via prefillFigmaMode. If not set, default to .
importmcp_figma_get_design_context — extracts exact layout structure, component hierarchy, spacing values, colors, typographymcp_figma_get_screenshot — captures a pixel-level visual referencemcp_figma_get_metadata — gets node names and file overviewcui-* componentprefillVision — describe the page as seen in Figma, mentioning which Coherence components will be used to recreate itprefillSuccessCriteria — one criterion per major UI section visible in the designprefillConstraints — include "Pixel-perfect recreation of Figma design using Coherence components and design tokens" as the first constraintprefillFigmaUrl, prefillFigmaMode ("import"), and prefillFigmaContextprefillVision — describe what the improved version will look like and why it's betterprefillProblem — describe the UX issues found in the current Figma designprefillSuccessCriteria — criteria that measure improvement (e.g. "Clearer information hierarchy", "Better whitespace usage", "Proper Coherence component usage")prefillConstraints — include "Use Figma design as reference only — build an improved solution using Coherence best practices" as the first constraintprefillFigmaUrl, prefillFigmaMode ("reference"), and prefillFigmaContextThe goal in both modes: after intent confirmation, the builder has enough detail to proceed without needing to re-call Figma tools. The key difference is whether it reproduces or improves.
This step is optional — skip it if no Figma URL is provided.
If the user's message or the orchestrator's dispatch includes a web URL (not Figma) — such as portal.azure.com, azure.microsoft.com, or any other web page — the visual-ingest skill has already captured the page and produced a reference document.
The orchestrator passes the web reference data via:
prefillWebUrl — the original URLprefillWebContext — the structured reference document (layout, component inventory, content, visual properties)If these fields are present, use them to derive prefill values the same way Figma data is used:
prefillVision — "A Coherence-based replica of [page title] featuring [key Coherence components mapped from the reference]"prefillSuccessCriteria — one criterion per major UI section identified in the web captureprefillConstraints — include "Brownfield: replicate existing web page design as starting point using Coherence components and design tokens" as the first constraintprefillVision — "An improved version of [page title], addressing [UX issues found]"prefillProblem — UX issues observed in the captured pageprefillSuccessCriteria — criteria measuring improvement over the referenceprefillConstraints — include "Use captured web page as reference only — build an improved solution using Coherence best practices"Priority: If both Figma and web reference data are present, use Figma (it's higher fidelity). Web reference is used when no Figma URL exists.
This step is optional — skip it if no web URL reference data is provided.
Parse the user's description and map to these fields:
| Field | Source | Example |
|---|---|---|
prefillVision | What they want to build | "A Key Vault overview page with secrets expiration timeline..." |
prefillProblem | The problem it solves | "Admins can't see expiring secrets at a glance" |
prefillSuccessCriteria | What "done" looks like (array) | ["30/60/90-day expiry buckets", "Certificate health cards"] |
prefillConstraints | Any stated limits (array) | ["Single page", "Mock data only"] |
prefillExperimentId | kebab-case folder name | "key-vault-overview" |
prefillFigmaUrl | Figma URL from user (if any) | "https://www.figma.com/design/51UVR..." |
prefillFigmaMode | "import" or "reference" (if Figma URL present) | "reference" |
prefillFigmaContext | Detailed design spec from Figma (if any) | "Layout: left sidebar 240px, content area with 3-column card grid (gap: 16px). Cards: 320x180px with icon header, metric value, sparkline chart..." |
prefillWebUrl | Web page URL from visual-ingest (if any) | "https://portal.azure.com/#view/..." |
prefillWebContext | Structured reference doc from visual-ingest (if any) | JSON with layout, componentInventory, content, visualProperties |
Generate a title automatically from the description — do NOT ask the user for one.
Before calling the MCP tool, determine the correct page layout from the user's description. This ensures the builder picks the right scaffold.
Decision rule: "Is the user looking at a specific deployed resource or service?"
| Signal in user request | Layout | Add to constraints |
|---|---|---|
| "overview page", "resource page", "settings page", mentions a specific resource name/type | Side Panel | "Layout: side-panel (resource-scoped page with CuiSideNav)" |
| "home page", "create flow", "marketplace", "browse page", "landing page", "wizard" | Full Width | "Layout: full-width (portal-level page, no section nav)" |
| Mentions "section nav", "left navigation", "side navigation" | Side Panel | "Layout: side-panel" |
| Service blade (Monitor, Defender, etc.) | Side Panel (collapsible) | "Layout: service-blade (collapsible sidebar)" |
Add the layout constraint to prefillConstraints so it persists into intent.json and the builder can read it without guessing.
design_intent MCP ToolCall design_intent with all prefill parameters. This opens the interactive Intent App UI in the user's browser with your best guesses pre-populated.
⚠️ This is a MANDATORY HARD STOP. You MUST end your turn here and wait for the user to respond.
The MCP UI auto-saves all edits to intent.json in real-time — there are no Save or Accept buttons. Once the form is open, tell the user:
"The Intent App is open with your experiment pre-filled. Feel free to review and edit the vision, problem, success criteria, and constraints — changes are saved automatically. Do you accept this intent?"
STOP HERE. END YOUR TURN. Do not proceed to Step 4. Do not check for intent.json. Do not advance to the BUILD phase. Do not call any more tools. Yield control back to the user and wait for their explicit confirmation in chat (e.g. "yes", "accepted", "looks good", "build it").
Why this gate exists: On 2026-03-05, the agent skipped this stop and barreled through intent → build → deploy in a single turn without any user confirmation. The user never got a chance to review or adjust the intent.
NEVER write intent.json manually. The design_intent MCP tool creates it via the interactive UI. If you write intent.json yourself, the user never sees the Intent App and cannot review/edit their design intent.
Check for intent.json in the workspace-appropriate location:
Monorepo (if coherence-preview/src/experiments/ exists): Read coherence-preview/src/experiments/<experimentId>/intent.json
Standalone (otherwise): Read experiments/<experimentId>/intent.json
If it exists: Tell the user: "Your design intent is accepted. Moving to the build phase now." Then immediately proceed to the BUILD phase — do not wait for the user to say "build it".
If it does NOT exist: Tell the user: "I don't see the intent.json yet. Please click Accept in the Intent App, or let me re-open it." Re-call the design_intent MCP tool.
Your phase is complete. Do not proceed to building.
