+# Expected Domain Arg Fix 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:** Fix browser_script_skill_tool to pass expected_domain to wrapped JS scripts.
+
+**Architecture:** Insert the normalized expected_domain back into args HashMap after domain normalization, before script wrapping.
+
+**Tech Stack:** Rust, serde_json
+
+---
+
+## Files
+
+- Modify: `src/compat/browser_script_skill_tool.rs:210` - Insert expected_domain back into args
+
+---
+
+### Task 1: Insert expected_domain into args
+
+**Files:**
+- Modify: `src/compat/browser_script_skill_tool.rs:210`
+
+- [ ] **Step 1: Add expected_domain to args after normalization**
+
+Edit `src/compat/browser_script_skill_tool.rs`, insert after line 209 (`eprintln!("[execute_browser_script_impl]   expected_domain: {}", expected_domain);`):
+
+```rust
+    args.insert("expected_domain".to_string(), Value::String(expected_domain.clone()));
+```
+
+The context around line 209-211 should look like this after the edit:
+
+```rust
+    eprintln!("[execute_browser_script_impl]   expected_domain: {}", expected_domain);
+    args.insert("expected_domain".to_string(), Value::String(expected_domain.clone()));
+
+    for required_arg in tool.args.keys() {
+```
+
+- [ ] **Step 2: Run tests to verify the fix**
+
+Run: `cargo test browser_script_skill_tool --no-fail-fast -- --nocapture`
+
+Expected: All tests pass, including `execute_browser_script_tool_runs_packaged_script_with_expected_domain`
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/compat/browser_script_skill_tool.rs
+git commit -m "fix: pass expected_domain to wrapped browser scripts"
+```
