+# Progressive Browser Script Template Enhancement Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Enhance the `browser_script_with_business_logic` template in Rust to generate complete, runnable browser scripts with proper HTTP handling, status determination, and error handling.
+
+**Architecture:** Modify `src/generated_scene/generator.rs` to replace the current incomplete JavaScript template with an enhanced version that includes: direct URL usage (fixing the URL construction bug), jQuery + fetch dual HTTP client support, complete status determination (blocked/error/partial/empty/ok), and enhanced entrypoint with page context validation.
+
+**Tech Stack:** Rust, JavaScript (browser script), serde_json
+
+---
+
+## File Structure
+
+| File | Action | Purpose |
+|------|--------|---------|
+| `src/generated_scene/generator.rs` | Modify | Replace `browser_script_with_business_logic` function with enhanced template |
+
+---
+
+### Task 1: Fix URL Building in buildRequest()
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs:308-321` (current `buildRequest` function in template)
+
+**Current bug:** The template uses `new URL(endpoint.url, window.location.origin)` which incorrectly constructs URLs based on the current page's origin instead of using the complete endpoint URL directly.
+
+**Goal:** Replace the buggy URL construction with direct URL usage.
+
+- [ ] **Step 1: Write the failing test**
+
+Create a test file to verify URL construction behavior:
+
+```javascript
+// Test that URL is used directly without window.location.origin
+const assert = require('assert');
+
+// Mock a complete URL in endpoint
+const endpoint = { url: 'http://20.76.57.61:18080/gsllys/api/test', method: 'POST' };
+
+// Expected: buildRequest should return the URL directly
+// NOT: new URL(endpoint.url, 'http://different-origin.com')
+```
+
+- [ ] **Step 2: Implement the fix**
+
+Replace the `buildRequest` function in `browser_script_with_business_logic` (lines 308-321 in the generated template):
+
+**Current (buggy):**
+```javascript
+function buildRequest(args, endpoint) {
+  const url = new URL(endpoint.url, window.location.origin);
+  const params = { ...STATIC_PARAMS, ...args };
+  for (const [key, value] of Object.entries(params)) {
+    if (value !== undefined && value !== null) {
+      url.searchParams.set(key, String(value));
+    }
+  }
+  return {
+    url: url.toString(),
+    method: endpoint.method || 'GET',
+    headers: { 'Content-Type': 'application/json' }
+  };
+}
+```
+
+**Fixed:**
+```javascript
+function buildRequest(args, endpoint) {
+  // Use endpoint.url directly - it's already a complete URL
+  const url = endpoint.url;
+  const method = endpoint.method || 'POST';
+  const headers = { 'Content-Type': 'application/json' };
+  const body = JSON.stringify({ ...STATIC_PARAMS, ...args });
+  return { url, method, headers, body };
+}
+```
+
+Locate this in `src/generated_scene/generator.rs` within the `browser_script_with_business_logic` function (around line 308 in the format! string). Replace the entire `buildRequest` function definition.
+
+- [ ] **Step 3: Verify the change**
+
+Run `cargo build` to verify the Rust code compiles:
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds without errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/generated_scene/generator.rs
+git commit -m "fix(generator): use endpoint.url directly in buildRequest to fix URL construction bug"
+```
+
+---
+
+### Task 2: Add jQuery + fetch Dual HTTP Client Support
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs:355-368` (current `defaultDeps` object in template)
+
+**Goal:** Add jQuery `$.ajax` as primary HTTP client with fetch as fallback for environments without jQuery.
+
+- [ ] **Step 1: Replace defaultDeps with enhanced version**
+
+Replace the current `defaultDeps` object in the template with enhanced jQuery + fetch support:
+
+**Current:**
+```javascript
+const defaultDeps = {
+  validatePageContext: async () => true,
+  queryData: async (args) => {
+    const endpoint = API_ENDPOINTS[0];
+    if (!endpoint) throw new Error('No API endpoint configured');
+    const request = buildRequest(args, endpoint);
+    const response = await fetch(request.url, {
+      method: request.method,
+      headers: request.headers
+    });
+    if (!response.ok) throw new Error(`HTTP ${response.status}: ${response.statusText}`);
+    return response.json();
+  }
+};
+```
+
+**Enhanced:**
+```javascript
+const defaultDeps = {
+  validatePageContext(args) {
+    const host = (globalThis.location?.hostname || '').trim();
+    const expected = (args.expected_domain || '').trim();
+    if (!host) return { ok: false, reason: 'page_context_unavailable' };
+    if (host !== expected) return { ok: false, reason: 'page_context_mismatch' };
+    return { ok: true };
+  },
+
+  async queryData(args) {
+    const endpoint = API_ENDPOINTS[0];
+    if (!endpoint) throw new Error('No API endpoint configured');
+    const request = buildRequest(args, endpoint);
+
+    // Prefer jQuery (internal pages typically have it)
+    if (typeof $ !== 'undefined' && typeof $.ajax === 'function') {
+      return new Promise((resolve, reject) => {
+        $.ajax({
+          url: request.url,
+          type: request.method,
+          data: request.body,
+          contentType: 'application/json',
+          dataType: 'json',
+          success: resolve,
+          error: (xhr, status, err) => reject(new Error(
+            `API failed (${xhr.status}): ${err} | body=${(xhr.responseText || '').substring(0, 200)}`
+          ))
+        });
+      });
+    }
+
+    // Fallback: fetch API
+    if (typeof fetch === 'function') {
+      const response = await fetch(request.url, {
+        method: request.method,
+        headers: request.headers,
+        body: request.method !== 'GET' ? request.body : undefined
+      });
+      if (!response.ok) {
+        const text = await response.text().catch(() => '');
+        throw new Error(`HTTP ${response.status}: ${text.substring(0, 200)}`);
+      }
+      return response.json();
+    }
+
+    throw new Error('No HTTP client available (need jQuery or fetch)');
+  }
+};
+```
+
+This code goes into the format! string in `browser_script_with_business_logic` function in `src/generated_scene/generator.rs`.
+
+- [ ] **Step 2: Verify the change**
+
+Run `cargo build` to verify:
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/generated_scene/generator.rs
+git commit -m "feat(generator): add jQuery + fetch dual HTTP client support in template"
+```
+
+---
+
+### Task 3: Add determineArtifactStatus Function
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs` (add new function to template before `buildArtifact`)
+
+**Goal:** Add complete status determination logic supporting blocked/error/partial/empty/ok statuses.
+
+- [ ] **Step 1: Add determineArtifactStatus function to template**
+
+Insert the following function into the template, before the `buildArtifact` function:
+
+```javascript
+function determineArtifactStatus({ blockedReason = '', fatalError = '', reasons = [], rows = [] }) {
+  if (blockedReason) return 'blocked';
+  if (fatalError) return 'error';
+  if (reasons.length > 0) return 'partial';
+  if (!rows.length) return 'empty';
+  return 'ok';
+}
+```
+
+This should be placed in the template string between `normalizeRows` and `buildArtifact` functions.
+
+- [ ] **Step 2: Verify the change**
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/generated_scene/generator.rs
+git commit -m "feat(generator): add determineArtifactStatus for complete status determination"
+```
+
+---
+
+### Task 4: Enhance buildArtifact Function
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs:334-353` (current `buildArtifact` function in template)
+
+**Goal:** Enhance `buildArtifact` to use `determineArtifactStatus` and accept additional parameters.
+
+- [ ] **Step 1: Replace buildArtifact function**
+
+Replace the current `buildArtifact` function with enhanced version:
+
+**Current:**
+```javascript
+function buildArtifact(args, rows) {
+  return {
+    type: 'report-artifact',
+    report_name: '{scene_id}',
+    status: rows.length > 0 ? 'ok' : 'empty',
+    period: {
+      mode: args.period_mode,
+      mode_code: args.period_mode_code,
+      value: args.period_value,
+      payload: normalizePayload(args.period_payload)
+    },
+    org: { label: args.org_label, code: args.org_code },
+    column_defs: COLUMN_DEFS,
+    columns: {columns_json},
+    rows,
+    counts: { detail_rows: rows.length },
+    partial_reasons: [],
+    reasons: []
+  };
+}
+```
+
+**Enhanced:**
+```javascript
+function buildArtifact({ status, blockedReason = '', fatalError = '', reasons = [], rows = [], args }) {
+  return {
+    type: 'report-artifact',
+    report_name: REPORT_NAME,
+    status: status || determineArtifactStatus({ blockedReason, fatalError, reasons, rows }),
+    period: {
+      mode: args.period_mode,
+      mode_code: args.period_mode_code,
+      value: args.period_value,
+      payload: normalizePayload(args.period_payload)
+    },
+    org: { label: args.org_label, code: args.org_code },
+    column_defs: COLUMN_DEFS,
+    columns: COLUMNS,
+    rows,
+    counts: { detail_rows: rows.length },
+    partial_reasons: reasons.filter(r => r && !r.startsWith('api_') && !r.startsWith('validation_')),
+    reasons: Array.from(new Set(reasons.filter(Boolean)))
+  };
+}
+```
+
+- [ ] **Step 2: Verify the change**
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/generated_scene/generator.rs
+git commit -m "feat(generator): enhance buildArtifact with determineArtifactStatus integration"
+```
+
+---
+
+### Task 5: Enhance buildBrowserEntrypointResult Function
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs:370-405` (current `buildBrowserEntrypointResult` function in template)
+
+**Goal:** Complete rewrite of entrypoint with proper validation flow, page context check, and error handling.
+
+- [ ] **Step 1: Replace buildBrowserEntrypointResult function**
+
+Replace the entire `buildBrowserEntrypointResult` function:
+
+**Current:**
+```javascript
+async function buildBrowserEntrypointResult(args, deps = defaultDeps) {
+  const validation = validateArgs(args);
+  if (!validation.valid) {
+    return {
+      type: 'report-artifact',
+      report_name: '{scene_id}',
+      status: 'error',
+      error: 'Validation failed: ' + validation.errors.join(', '),
+      column_defs: COLUMN_DEFS,
+      columns: {columns_json},
+      rows: [],
+      counts: { detail_rows: 0 },
+      partial_reasons: [],
+      reasons: validation.errors
+    };
+  }
+
+  try {
+    const rawData = await (deps.queryData ? deps.queryData(args) : Promise.resolve([]));
+    const rows = normalizeRows(rawData);
+    return buildArtifact(args, rows);
+  } catch (error) {
+    return {
+      type: 'report-artifact',
+      report_name: '{scene_id}',
+      status: 'error',
+      error: error.message,
+      column_defs: COLUMN_DEFS,
+      columns: {columns_json},
+      rows: [],
+      counts: { detail_rows: 0 },
+      partial_reasons: [],
+      reasons: [error.message]
+    };
+  }
+}
+```
+
+**Enhanced:**
+```javascript
+async function buildBrowserEntrypointResult(args, deps = defaultDeps) {
+  // 1. Parameter validation
+  const validation = validateArgs(args);
+  if (!validation.valid) {
+    return buildArtifact({
+      status: 'blocked',
+      blockedReason: 'validation_failed',

+```
+
+---
+
+### Task 6: Add Helper Functions and Constants
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs` (add helper functions to template)
+
+**Goal:** Add utility functions used by the enhanced template.
+
+- [ ] **Step 1: Add helper functions after COLUMN_DEFS constant**
+
+Add these utility functions to the template after the constant definitions:
+
+```javascript
+const REPORT_NAME = '{scene_id}';
+const COLUMNS = {columns_json};
+
+function pickFirstNonEmpty(...values) {
+  for (const value of values) {
+    if (typeof value === 'string' && value.trim() !== '') {
+      return value.trim();
+    }
+  }
+  return '';
+}
+
+function isNonEmptyString(value) {
+  return typeof value === 'string' && value.trim() !== '';
+}
+```

+- [ ] **Step 2: Verify the change**
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 3: Commit**
+
+```bash

+git commit -m "feat(generator): add helper functions for enhanced template"
+```
+
+---
+
+### Task 7: Update Module Exports
+
+**Files:**
+- Modify: `src/generated_scene/generator.rs:407-409` (current module.exports in template)
+
+**Goal:** Update module exports to include new functions.
+
+- [ ] **Step 1: Update module.exports**
+
+Replace the current export block:
+
+**Current:**
+```javascript
+if (typeof module !== 'undefined') {
+  module.exports = { buildBrowserEntrypointResult, normalizePayload, validateArgs, buildRequest, normalizeRows, buildArtifact, API_ENDPOINTS, STATIC_PARAMS, COLUMN_DEFS };
+}
+```
+
+**Enhanced:**
+```javascript
+if (typeof module !== 'undefined') {
+  module.exports = {
+    buildBrowserEntrypointResult,
+    normalizePayload,
+    validateArgs,
+    buildRequest,
+    normalizeRows,
+    determineArtifactStatus,
+    buildArtifact,
+    API_ENDPOINTS,
+    STATIC_PARAMS,
+    COLUMN_DEFS,
+    COLUMNS,
+    REPORT_NAME
+  };
+}
+```
+
+- [ ] **Step 2: Verify the change**
+
+```bash
+cargo build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/generated_scene/generator.rs
+git commit -m "feat(generator): update module exports for enhanced template"
+```
+
+---
+
+### Task 8: Integration Test - Generate and Verify Script
+
+**Files:**
+- Test: Generate a skill package and verify the output
+
+**Goal:** Verify the enhanced template generates valid JavaScript.
+
+- [ ] **Step 1: Build the project**
+
+```bash
+cargo build --release
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 2: Generate a test skill package**
+
+Use the scene generator to create a test skill:
+
+```bash
+# Assuming you have a test scene directory
+cargo run --bin sg_scene_generate -- --source-dir "examples/test-scene" --scene-id "test-enhanced" --scene-name "Test Enhanced" --output-root "tmp_test_enhanced" --scene-info-json '{"sceneId":"test-enhanced","sceneName":"Test Enhanced","apiEndpoints":[{"name":"testApi","url":"http://example.com/api/test","method":"POST"}],"staticParams":{},"columnDefs":[["col1","Column 1"]]}'
+```
+
+Expected: Skill package generated without errors.
+
+- [ ] **Step 3: Verify generated script syntax**
+
+Check the generated JavaScript for syntax errors:
+
+```bash
+node --check tmp_test_enhanced/skills/test-enhanced/scripts/collect_test_enhanced.js
+```
+
+Expected: No syntax errors.
+
+- [ ] **Step 4: Run the generated test**
+
+```bash
+node tmp_test_enhanced/skills/test-enhanced/scripts/collect_test_enhanced.test.js
+```
+
+Expected: Test passes (may fail on API call, but artifact structure should be valid).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add -A
+git commit -m "test: verify enhanced template generates valid JavaScript"
+```

+## Execution Handoff
+
+Plan complete and saved to `docs/superpowers/plans/2026-04-17-progressive-template-enhancement-plan.md`. Two execution options:
+
+**1. Subagent-Driven (recommended)** - I dispatch a fresh subagent per task, review between tasks, fast iteration
+
+**2. Inline Execution** - Execute tasks in this session using executing-plans, batch execution with checkpoints
+
+Which approach?
