---description: Resume or start track implementation following TDD protocolagent: tier2-tech-lead---# /conductor-implementResume or start implementation of the active track following TDD protocol.## Prerequisites- Run `/conductor-setup` first to load context- Ensure a track is active (has `[~]` tasks)## CRITICAL: Use MCP Tools OnlyAll research and file operations must use Manual Slop's MCP tools:- `manual-slop_py_get_code_outline` - structure analysis- `manual-slop_py_get_skeleton` - signatures + docstrings- `manual-slop_py_find_usages` - find references- `manual-slop_get_git_diff` - recent changes- `manual-slop_run_powershell` - shell commands## Implementation Protocol1. **Identify Current Task:**   - Read active track's `plan.md` via `manual-slop_read_file`   - Find the first `[~]` (in-progress) or `[ ]` (pending) task   - If phase has no pending tasks, move to next phase2. **Research Phase (MANDATORY):**   Before implementing, use MCP tools to understand context:   - `manual-slop_py_get_code_outline` on target files   - `manual-slop_py_get_skeleton` on dependencies   - `manual-slop_py_find_usages` for related patterns   - `manual-slop_get_git_diff` for recent changes   - Audit `__init__` methods for existing state3. **TDD Cycle:**   ### Red Phase (Write Failing Tests)   - Stage current progress: `manual-slop_run_powershell` with `git add .`   - Delegate test creation to @tier3-worker:     ```     @tier3-worker          Write tests for: [task description]          WHERE: tests/test_file.py:line-range     WHAT: Test [specific functionality]     HOW: Use pytest, assert [expected behavior]     SAFETY: [thread-safety constraints]          Use 1-space indentation. Use MCP tools only.     ```   - Run tests: `manual-slop_run_powershell` with `uv run pytest tests/test_file.py -v`   - **CONFIRM TESTS FAIL** - this is the Red phase   ### Green Phase (Implement to Pass)   - Stage current progress: `manual-slop_run_powershell` with `git add .`   - Delegate implementation to @tier3-worker:     ```     @tier3-worker          Implement: [task description]          WHERE: src/file.py:line-range     WHAT: [specific change]     HOW: [API calls, patterns to use]     SAFETY: [thread-safety constraints]          Use 1-space indentation. Use MCP tools only.     ```   - Run tests: `manual-slop_run_powershell` with `uv run pytest tests/test_file.py -v`   - **CONFIRM TESTS PASS** - this is the Green phase   ### Refactor Phase (Optional)   - With passing tests, refactor for clarity   - Re-run tests to verify4. **Commit Protocol (ATOMIC PER-TASK):**   Use `manual-slop_run_powershell`:   ```powershell   git add .   git commit -m "feat(scope): description"   $hash = git log -1 --format="%H"   git notes add -m "Task: [summary]" $hash   ```   - Update `plan.md`: Change `[~]` to `[x]` with commit SHA   - Commit plan update: `git add plan.md && git commit -m "conductor(plan): Mark task complete"`5. **Repeat for Next Task**## Error HandlingIf tests fail after Green phase:- Delegate analysis to @tier4-qa:  ```  @tier4-qa    Analyze this test failure:    [test output]    DO NOT fix - provide analysis only. Use MCP tools only.  ```- Maximum 2 fix attempts before escalating to user## Phase CompletionWhen all tasks in a phase are `[x]`:- Run `/conductor-verify` for checkpoint
