# implement

The command works through unfinished Conductor track tasks and updates their status. With TDD enabled, it writes a failing test before implementing the change.

## What it does

Before starting, the command checks that Conductor is set up and reads `conductor/workflow.md` for TDD strictness, commit strategy, and phase checks. It selects a track by ID or from the incomplete tracks listed in `conductor/tracks.md`, then loads the plan, spec, metadata, and project context.

For each task, it updates the plan, runs tests, and commits changes according to the workflow configuration. When a phase is done, it runs the listed checks and waits for explicit approval before moving on. Tool, test, and Git failures stop the run and prompt the agent to offer next steps.

Conductor needs to be initialized first: `conductor/product.md`, `conductor/workflow.md`, and `conductor/tracks.md` must exist. If they do not, the command suggests running `/conductor:setup`. At the end, it checks acceptance criteria and offers to sync documentation and archive, delete, or keep the track.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install conductor@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/commands/implement.md` — Call it with /implement. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/implement.md` — Call it with /prompts:implement. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/implement.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/implement.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/conductor/commands/implement.md

## When to use it
- work through unfinished tasks in a track plan
- apply a TDD cycle to planned changes
- update task status and track progress
- pause when tests or Git operations fail
- verify a finished phase and request approval

## Example prompts
- Implement the plan for track `auth_20250115` using the Conductor workflow.
- Work on task `2.3` in track `auth_20250115` with TDD enabled.
- Continue the unfinished track, then pause after phase verification for my approval.

# Implement Track

Execute tasks from a track's implementation plan, following the workflow rules defined in `conductor/workflow.md`.

## Pre-flight Checks

1. Verify Conductor is initialized:
   - Check `conductor/product.md` exists
   - Check `conductor/workflow.md` exists
   - Check `conductor/tracks.md` exists
   - If missing: Display error and suggest running `/conductor:setup` first

2. Load workflow configuration:
   - Read `conductor/workflow.md`
   - Parse TDD strictness level
   - Parse commit strategy
   - Parse verification checkpoint rules

## Track Selection

### If argument provided:

- Validate track exists: `conductor/tracks/{argument}/plan.md`
- If not found: Search for partial matches, suggest corrections

### If no argument:

1. Read `conductor/tracks.md`
2. Parse for incomplete tracks (status `[ ]` or `[~]`)
3. Display selection menu:

   ```
   Select a track to implement:

   In Progress:
   1. [~] auth_20250115 - User Authentication (Phase 2, Task 3)

   Pending:
   2. [ ] nav-fix_20250114 - Navigation Bug Fix
   3. [ ] dashboard_20250113 - Dashboard Feature

   Enter number or track ID:
   ```

## Context Loading

Load all relevant context for implementation:

1. Track documents:
   - `conductor/tracks/{trackId}/spec.md` - Requirements
   - `conductor/tracks/{trackId}/plan.md` - Task list
   - `conductor/tracks/{trackId}/metadata.json` - Progress state

2. Project context:
   - `conductor/product.md` - Product understanding
   - `conductor/tech-stack.md` - Technical constraints
   - `conductor/workflow.md` - Process rules

3. Code style (if exists):
   - `conductor/code_styleguides/{language}.md`

## Track Status Update

Update track to in-progress:

1. In `conductor/tracks.md`:
   - Change `[ ]` to `[~]` for this track

2. In `conductor/tracks/{trackId}/metadata.json`:
   - Set `status: "in_progress"`
   - Update `updated` timestamp

## Task Execution Loop

For each incomplete task in plan.md (marked with `[ ]`):

### 1. Task Identification

Parse plan.md to find next incomplete task:

- Look for lines matching `- [ ] Task X.Y: {description}`
- Track current phase from structure

### 2. Task Start

Mark task as in-progress:

- Update plan.md: Change `[ ]` to `[~]` for current task
- Announce: "Starting Task X.Y: {description}"

### 3. TDD Workflow (if TDD enabled in workflow.md)

**Red Phase - Write Failing Test:**

```
Following TDD workflow for Task X.Y...

Step 1: Writing failing test
```

- Create test file if needed
- Write test(s) for the task functionality
- Run tests to confirm they fail
- If tests pass unexpectedly: HALT, investigate

**Green Phase - Implement:**

```
Step 2: Implementing minimal code to pass test
```

- Write minimum code to make test pass
- Run tests to confirm they pass
- If tests fail: Debug and fix

**Refactor Phase:**

```
Step 3: Refactoring while keeping tests green
```

- Clean up code
- Run tests to ensure still passing

### 4. Non-TDD Workflow (if TDD not strict)

- Implement the task directly
- Run any existing tests
- Manual verification as needed

### 5. Task Completion

**Commit changes** (following commit strategy from workflow.md):

```bash
git add -A
git commit -m "{commit_prefix}: {task description} ({trackId})"
```

**Update plan.md:**

- Change `[~]` to `[x]` for completed task
- Commit plan update:

```bash
git add conductor/tracks/{trackId}/plan.md
git commit -m "chore: mark task X.Y complete ({trackId})"
```

**Update metadata.json:**

- Increment `tasks.completed`
- Update `updated` timestamp
