+# Browser Script Skill Capability Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Let zeroclaw-backed sgclaw skills call deterministic browser-context scripts through existing SuperRPA page-execution capabilities.
+
+**Architecture:** Reuse SuperRPA's existing page script execution path instead of inventing a parallel workflow executor. Extend sgclaw's browser pipe and zeroclaw skill-tool mapping so a skill can declare a browser script tool, execute a packaged script file with parameters, and receive structured JSON back in the current page context.
+
+**Tech Stack:** Rust (`sgclaw`, vendored `zeroclaw`), Chromium/SuperRPA C++, existing sgclaw browser pipe protocol, skill package `SKILL.toml` / `scripts/`.
+
+### Task 1: Define the browser-script contract
+
+**Files:**
+- Modify: `third_party/zeroclaw/src/skills/mod.rs`
+- Modify: `third_party/zeroclaw/src/tools/mod.rs`
+- Create: `third_party/zeroclaw/src/tools/browser_script_skill.rs`
+- Test: `tests/compat_browser_tool_test.rs`
+
+**Step 1: Write the failing test**
+
+Add a sgclaw-side test proving the browser tool schema accepts a script execution action with required browser-script fields and rejects missing script payload.
+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo test --manifest-path /home/zyl/projects/sgClaw/claw/Cargo.toml --test compat_browser_tool_test`
+Expected: FAIL because the browser tool still exposes only `click/type/navigate/getText`.
+
+**Step 3: Write minimal implementation**
+
+Extend the browser tool adapter and protocol-facing action parsing to support a deterministic script execution action carrying:
+- `action`
+- `expected_domain`
+- `script`
+- optional `args`
+
+**Step 4: Run test to verify it passes**
+
+Run: `cargo test --manifest-path /home/zyl/projects/sgClaw/claw/Cargo.toml --test compat_browser_tool_test`
+Expected: PASS for the new browser script action coverage.
+
+**Step 5: Commit**
+
+```bash
+git add tests/compat_browser_tool_test.rs src/compat/browser_tool_adapter.rs src/pipe/protocol.rs third_party/zeroclaw/src/skills/mod.rs third_party/zeroclaw/src/tools/mod.rs third_party/zeroclaw/src/tools/browser_script_skill.rs
+git commit -m "feat: add browser script skill tool support"
+```
+
+### Task 2: Wire browser script execution through the sgclaw host bridge
+
+**Files:**
+- Modify: `src/pipe/protocol.rs`
+- Modify: `/home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_pipe_protocol.cc`
+- Modify: `/home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_security_gate.cc`
+- Test: `/home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_pipe_protocol_mainline_unittest.cc`
+- Test: `/home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_process_host_mainline_unittest.cc`
+
+**Step 1: Write the failing tests**
+
+Add host-side tests proving:
+- sgclaw protocol accepts the new browser script action
+- handshake advertises the action
+- the security gate allows it only through the sgclaw host allowlist
+
+**Step 2: Run tests to verify they fail**
+
+Run the relevant SuperRPA unit tests.
+Expected: FAIL because the host protocol and allowlist do not yet include browser script execution.
+
+**Step 3: Write minimal implementation**
+
+Reuse existing SuperRPA router support by bridging the new sgclaw action to the host's page script execution capability instead of inventing a second execution path.
+
+**Step 4: Run tests to verify they pass**
+
+Run the same SuperRPA unit tests.
+Expected: PASS with the new action accepted end-to-end.
+
+**Step 5: Commit**
+
+```bash
+git add src/pipe/protocol.rs /home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_pipe_protocol.cc /home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_security_gate.cc /home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_pipe_protocol_mainline_unittest.cc /home/zyl/projects/superRpa/src/chrome/browser/superrpa/sgclaw/sgclaw_process_host_mainline_unittest.cc
+git commit -m "feat: expose browser script execution to sgclaw"
+```
+
+### Task 3: Convert Zhihu hotlist collection into a script-backed skill path
+
+**Files:**
+- Create: `/home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/SKILL.toml`
+- Create: `/home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/scripts/extract_hotlist.js`
+- Modify: `/home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/SKILL.md`
+- Modify: `tests/compat_runtime_test.rs`
+
+**Step 1: Write the failing test**
+
+Add runtime coverage proving the Zhihu hotlist export flow uses the skill-backed browser script tool instead of repeated `getText` probing.
+
+**Step 2: Run test to verify it fails**
+
+Run: `cargo test --manifest-path /home/zyl/projects/sgClaw/claw/Cargo.toml --test compat_runtime_test`
+Expected: FAIL because the current flow still uses `read_skill` plus generic `getText`.
+
+**Step 3: Write minimal implementation**
+
+Package the hotlist extractor as a deterministic browser script tool returning structured rows and update the skill description to require that tool before export.
+
+**Step 4: Run test to verify it passes**
+
+Run: `cargo test --manifest-path /home/zyl/projects/sgClaw/claw/Cargo.toml --test compat_runtime_test`
+Expected: PASS with the script-backed tool visible in logs and the generic repeated `getText` fallback removed from the primary path.
+
+**Step 5: Commit**
+
+```bash
+git add /home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/SKILL.toml /home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/scripts/extract_hotlist.js /home/zyl/projects/sgClaw/skill_lib/skills/zhihu-hotlist/SKILL.md tests/compat_runtime_test.rs
+git commit -m "feat: make zhihu hotlist extraction script-backed"
+```
+
+### Task 4: Fix plan visibility in the sgclaw frontend
+
+**Files:**
+- Modify: `/home/zyl/projects/superRpa/src/chrome/browser/resources/superrpa/devtools/functions/sgclaw-chat/sgclaw-chat_state.ts`
+- Modify: `/home/zyl/projects/superRpa/src/chrome/browser/resources/superrpa/devtools/functions/sgclaw-chat/sgclaw-chat.ts`
+- Test: frontend or host tests covering `[sgclaw/plan]`
+
+**Step 1: Write the failing test**
+
+Add coverage proving `[sgclaw/plan]` logs are treated as planner logs and preserve multiline task-step rendering.
+
+**Step 2: Run test to verify it fails**
+
+Run the relevant frontend or browser-side tests.
+Expected: FAIL because the current frontend only recognizes `[browser/plan]` or `[plan]`.
+
+**Step 3: Write minimal implementation**
+
+Accept `[sgclaw/plan]` as a planner log source and keep the plan text rendered as multiple visible lines.
+
+**Step 4: Run test to verify it passes**
+
+Run the same tests.
+Expected: PASS with sgclaw planner logs rendered correctly.
+
+**Step 5: Commit**
+
+```bash
+git add /home/zyl/projects/superRpa/src/chrome/browser/resources/superrpa/devtools/functions/sgclaw-chat/sgclaw-chat_state.ts /home/zyl/projects/superRpa/src/chrome/browser/resources/superrpa/devtools/functions/sgclaw-chat/sgclaw-chat.ts
+git commit -m "fix: render sgclaw planner logs in chat ui"
+```
+
+### Task 5: Full verification
+
+**Files:**
+- Verify only
+
+**Step 1: Run sgclaw Rust tests**
+
+Run: `cargo test --manifest-path /home/zyl/projects/sgClaw/claw/Cargo.toml`
+Expected: PASS.
+
+**Step 2: Run relevant SuperRPA unit tests**
+
+Run the updated sgclaw host and frontend tests.
+Expected: PASS.
+
+**Step 3: Run a manual browser acceptance flow**
+
+Verify that:
+- startup logs include runtime and skill versions
+- `[sgclaw/plan]` is shown as a real multi-line plan
+- Zhihu hotlist export invokes the script-backed skill tool
+- the flow returns a real `.xlsx` path without repeated self-referential output
+
+**Step 4: Commit verification artifacts if needed**
+
+Keep verification commits separate from behavior changes.
