Output And Evidence

• Save list/summarize outputs under output/alibabacloud-wxz-website-builder/.
• Keep conversation IDs and event summaries in each evidence file.

Prerequisites

pip install -r requirements.txt

• All dependencies are pinned to exact versions in requirements.txt.
• Credentials are resolved via the default credential chain (no explicit AK/SK needed).

Authentication

This skill relies on the Alibaba Cloud default credential chain. Do NOT set AK/SK explicitly. The SDK automatically resolves credentials in the following order:

1. Environment variables: ALIBABACLOUD_ACCESS_KEY_ID / ALIBABACLOUD_ACCESS_KEY_SECRET
2. Shared config file: ~/.alibabacloud/credentials
3. RAM role / ECS metadata service (when running on Alibaba Cloud instances)

Region: ALIBABACLOUD_REGION_ID defaults to cn-hangzhou.

How to obtain AccessKey (if user doesn't have one)

If the user has no AccessKey yet, guide them through these steps (see references/ak-setup-guide.md for full details):

1. Login: Open https://www.aliyun.com and log in (or register)
2. Create RAM user: Go to https://ram.console.aliyun.com/users → "Create User" → check "OpenAPI Access" → save the AK/SK immediately (Secret is only shown once!)
3. Grant permissions: Add a custom policy with the following Actions (least-privilege):
   • zero2staff:CreateAIStaffConversation
   • zero2staff:CreateAIStaffChat
   • zero2staff:ListAIStaffChatEvents
   • zero2staff:ListAIStaffChatMessages
   • zero2staff:GetAIStaffPreviewUrl
4. Configure: Write to ~/.alibabacloud/credentials or set environment variables

CRITICAL: When guiding the user, remind them:

• Do NOT use root account AccessKey — always use RAM sub-user
• Save the AccessKey Secret immediately — it's only shown once during creation
• Never commit AccessKey to git

If the user encounters auth errors, refer to the troubleshooting table in references/ak-setup-guide.md.

Application Lifecycle

The complete flow has 3 phases. Follow them sequentially.

IMPORTANT — Agent-driven polling: The chat command fires the request and returns immediately. The agent then drives the polling loop via the poll command. Between each poll, the agent MUST show the user a progress message so they know what's happening (use progressDetail for rich messages).

Phase 1: Create Conversation
        ↓
Phase 2: Fire requirement chat → poll → HITL → Fire resume → poll → ... → PRD ready
        ↓
Phase 3: Fire code generation → Show link → poll loop with progress → Get preview URL → Done

Phase 0: Auth Setup

Ensure Alibaba Cloud credentials are configured via the default credential chain (see Authentication section above).

Phase 1: Create Conversation

MUST create a conversation before any chat operation:

CONV=$(python scripts/aistaff_api.py create-conversation --text "build a popmart homepage")
CONV_ID=$(echo $CONV | jq -r '.ConversationId')
CHAT_ID=$(echo $CONV | jq -r '.ChatId')
SITE_ID=$(echo $CONV | jq -r '.SiteId')

Returns flat JSON: {ConversationId, SiteId, ChatId, SectionId, BotId, Title}.

Phase 2: Requirement Collection + PRD

This phase collects requirements and generates a PRD. The platform may ask multiple HITL rounds (basic info → features → language, etc.). To keep things fast:

• Only the first HITL round should be shown to the user (basic project info).
• All subsequent HITL rounds must be auto-filled with the form's default/pre-selected values and resumed immediately — do NOT ask the user.

Step 1: Fire requirement collection

python scripts/aistaff_api.py chat \
  --text "build a popmart homepage" \
  --conversation-id $CONV_ID \
  --biz-id $SITE_ID

Tell user: "Analyzing your requirements, please wait..."

Step 2: Poll until first HITL form arrives

Call poll every 5 seconds until phase is waiting_for_input:

python scripts/aistaff_api.py poll \
  --conversation-id $CONV_ID \
  --biz-id $SITE_ID \
  --last-event-id 0

Between each poll, show the user a progress message based on phase:

• processing → "Analyzing requirements..."
• fetching_reference → "Fetching reference site info..."
• waiting_for_input → First HITL form arrived, proceed to Step 3.

Step 3: First HITL — collect answers from user

Extract questions from the metaData.arguments of the message.tool event where name: "AskUserQuestion". Present these questions to the user via the AskUserQuestion tool (typically: app name, business description, target users, reference site).

Step 4: Fire resume with --phase generate_prd

CRITICAL: On the first HITL resume, always pass --phase generate_prd --user-navigation generate_prd.

python scripts/aistaff_api.py chat \
  --text '{"App Name": "POP MART Official", "Main Service": "Trendy Toys", "Target Users": "Gen Z trendsetters", "Reference Site": "None"}' \
  --conversation-id $CONV_ID \
  --biz-id $SITE_ID \
  --chat-id $CHAT_ID \
  --chat-status interrupt \
  --phase generate_prd \
  --user-navigation generate_prd \
  --hidden --without-refer

The --text JSON keys MUST match the header values from the form.

Tell user: "Requirements received, generating product plan..."

Step 5: Poll loop — auto-fill subsequent HITL rounds until PRD is ready

Poll every 5 seconds. Based on phase / summary, take action:

• phase == "waiting_for_input" (another HITL question) → Auto-fill immediately using the answers field from the AskUserQuestion event, then fire resume again. Tell user: "Refining requirement details..."
• phase == "generating_prd" → Tell user: "Generating PRD, please wait..."
• phase == "fetching_reference" → Tell user: "Fetching reference materials..."
• summary.chatStatus == "success" + summary.hasPrd == true → PRD ready, proceed to Phase 3.
• summary.chatStatus == "fail" → Ask user whether to retry.

# Poll:
python scripts/aistaff_api.py poll \
  --conversation-id $CONV_ID --biz-id $SITE_ID --last-event-id $LAST_EVENT_ID

# Auto-fill (use the "answers" field from the AskUserQuestion event):
python scripts/aistaff_api.py chat \
  --text '{"Core Features": ["Product Showcase", "Brand Story", "News"]}' \
  --conversation-id $CONV_ID --biz-id $SITE_ID --chat-id $CHAT_ID \
  --chat-status interrupt --phase generate_prd \
  --user-navigation generate_prd --hidden --without-refer

Key rule: The platform's AskUserQuestion event always includes an answers field with sensible defaults. For rounds after the first, always use these defaults directly instead of prompting the user.

Phase 3: Code Generation

When PRD is ready:

Step 1: Fire code generation

python scripts/aistaff_api.py chat \
  --text "Confirm app generation" \
  --conversation-id $CONV_ID \
  --biz-id $SITE_ID \
  --phase generate_code \
  --without-refer

Step 2: Show site link immediately

MUST show before and after code generation:

https://wanwang.aliyun.com/webdesign/home#/ai/manage/prd?conversationId=<CONV_ID>

Tell user: "Code generation started. This typically takes 2-5 minutes. You can check the project via the link above while I track the progress..."

Step 3: Poll loop with progress updates

Poll every 10 seconds. Show the user progress between each poll:

python scripts/aistaff_api.py poll \
  --conversation-id $CONV_ID --biz-id $SITE_ID --last-event-id $LAST_EVENT_ID

Progress messages (use progressDetail for rich messages):

• phase == "processing" + latestFile exists → "Generating code... Writing: {latestFile.semantic} ({filesWrittenCount} files generated)"
• phase == "processing" + no latestFile → "Generating code... N events processed"
• phase == "processing" + lastMessage exists → Also show the assistant's latest message as context
• phase == "success" → Site is ready! Proceed to Step 4.
• phase == "fail" → Ask user whether to retry.

Step 4: Get preview URL

MUST call this after code generation completes (summary.chatStatus == "success"). Starts the preview sandbox and returns the live preview URL.

PREVIEW=$(python scripts/aistaff_api.py get-preview-url --conversation-id $CONV_ID)
PREVIEW_URL=$(echo $PREVIEW | jq -r '.urlMap.https // .urlMap.http // empty')

Tell user: "Site built! Getting preview URL..."

The first call may take a few seconds as the sandbox starts up. If the preview URL is not yet available, retry after 10 seconds (up to 3 retries). Show the preview URL: "Preview URL: {PREVIEW_URL}"

--restart: Pass --restart to restart the app in the sandbox (e.g., after a modification). Not needed for the initial build.

Step 5: Handle completion

• summary.chatStatus == "success" → Site is ready. Show site link + preview URL.
• summary.chatStatus == "fail" or summary.hasError == true → Ask user whether to retry. Do NOT auto-retry.

After Initial Generation

• Use chat with --conversation-id to modify the site.
• Each modification uses the same chat + poll pattern.
• After each modification completes, call get-preview-url --restart to refresh the preview.
• Show the site link + preview URL again after each modification.

Decision Table

Available Commands

create-conversation

python scripts/aistaff_api.py create-conversation --text "user question"

Returns: {ConversationId, SiteId, ChatId, SectionId, BotId, Title}.

chat

Fire an async chat message and return immediately. Automatically drains old SSE events before firing. Use poll afterwards to track progress.

python scripts/aistaff_api.py chat --text "description" --conversation-id <ID> --biz-id <ID> [options]

Key parameters:

• --text TEXT: Message text or form answers JSON (required)
• --conversation-id ID / --biz-id ID: Required identifiers
• --chat-id ID + --chat-status interrupt: For HITL resume
• --phase {requirement_collect,generate_prd,generate_code}: Phase to enter
• --user-navigation TARGET: Navigation target (use generate_prd with --phase generate_prd)
• --hidden / --without-refer: Hide message / skip reference context
• --verbose: Show debug info

Returns: {conversationId, chatId, status: "fired", error}.

poll

Single-shot status check — fetches new events once + checks message status, then returns immediately. Designed for agent-driven polling loops.

python scripts/aistaff_api.py poll --conversation-id <ID> --biz-id <ID> [--last-event-id N]

Key parameters:

• --last-event-id N: Cursor from previous poll (default: 0). Pass the lastEventId from the previous poll result.
• --max-output-events N: Limit events in output (default: 10, 0=unlimited)

Returns: {conversationId, lastEventId, newEvents, phase, summary, progressDetail, events}

summary fields: chatStatus, hasError, errorMsg, hasPrd, toolsCalled

progressDetail fields — use these to build informative progress messages:

• filesWrittenCount: Total files generated so far
• activeTools: Tools currently in progress (status=wait). Empty when all completed
• latestFile: {path, semantic, status} — most recent file being written (show semantic to user)
• allFiles: Complete list of files written, each with path and semantic
• lastMessage: Latest assistant text message (truncated to 200 chars)
• toolProgress: Per-tool status list with name, status (wait/done), semantic

Suggested progress messages:

• latestFile.status == "wait": "Generating: {latestFile.semantic}..."
• latestFile.status == "done" + activeTools empty: "{filesWrittenCount} files completed, waiting for next step..."
• filesWrittenCount > 0 + activeTools not empty: "Generating code... {filesWrittenCount} files done, writing: {latestFile.semantic}"
• lastMessage not empty: Show it as additional context

phase values:

list-messages

Query the latest chat messages. Returns the last N messages (default: 10).

python scripts/aistaff_api.py list-messages --conversation-id <ID> [--tail 10]

Key usage: Use this to check ChatStatus of the last message when poll shows no progress.

get-preview-url

Get the live preview URL after code generation. Starts the sandbox if needed.

python scripts/aistaff_api.py get-preview-url --conversation-id <ID> [--restart]

Parameters: --conversation-id ID (required), --restart (restart app in sandbox, useful after modifications)

Returns: {urlMap: {https: "...", http: "...", sessionId: "..."}}

MUST call after chatStatus == "success" in Phase 3. First call may take a few seconds (sandbox startup). If URL is empty, retry after 10s (up to 3 retries).

SSE Event Constraints

• Each new chat round may wipe previous SSE events. The chat command automatically drains old events before firing.
• When using poll, pass the lastEventId from the previous poll result to avoid re-processing events.
• During code generation, the platform may auto-trigger multiple "magic fix" rounds. The poll command detects this via event summary.
