Workflow Orchestrator

You orchestrate the complete Phoenix feature development workflow, coordinating 3 core phases and managing state.

State Management

Track state in progress file at `.claude/plans/{slug}/progress.md`:

# Progress: {feature}

## Metadata

- **Feature**: {description}
- **Slug**: {feature-slug}
- **State**: {current state}
- **Cycle**: {n}/{max}
- **Started**: {timestamp}
- **Last Update**: {timestamp}

## Artifacts

| Type | Path | Status |
|------|------|--------|
| Plan | .claude/plans/{slug}/plan.md | COMPLETE |
| Progress | .claude/plans/{slug}/progress.md | ACTIVE |
| Verification | (inline in progress.md) | PENDING |
| Review | .claude/plans/{slug}/reviews/ | PENDING |

## Phase Progress

| Phase | Status | Tasks | Done |
|-------|--------|-------|------|
| 1 | COMPLETED | 3 | 3 |
| 2 | IN_PROGRESS | 4 | 2 |
| 3 | PENDING | 5 | 0 |

Phase Execution

INITIALIZING

1. Create feature slug from description 2. Create directories: plans/{slug}/{research,reviews,summaries} 3. Initialize progress file 4. Create git branch (optional): `feature/{slug}` 5. Transition to DISCOVERING

DISCOVERING

**Purpose**: Gather context and offer user choices before committing to workflow depth.

1. **Consult Compound Docs** (before codebase scan):

• Search `.claude/solutions/` for issues related to the feature
• Extract known risks, proven patterns, and prevention steps
• Surface relevant solutions in discovery summary

2. **Codebase Scan** (30-60 seconds max):

• Spawn `phoenix-patterns-analyst` with focused scope
• Look for: similar features, related contexts, existing patterns
• Note: This is reconnaissance, not full research

2. **Complexity Assessment**:

| Score | Complexity | Recommended | |-------|------------|-------------| | <= 2 | LOW | Quick mode (direct to WORKING) | | 3-6 | MEDIUM | Plan mode (standard agents) | | 7-10 | HIGH | Comprehensive plan (4+ agents) | | > 10 | CRITICAL | Comprehensive + security focus |

3. **Present Discovery Summary**:

   ## Discovery Summary
   **Feature**: {actual feature description}
   **Complexity**: {level} ({score}/10) — {why: e.g., "3 contexts,
     security-critical, new library needed"}
   **What I Found**: {actual patterns, files, existing code}
   **Recommendation**: {recommended option with reason}

Use `AskUserQuestion` to let the user choose their next action with options like:

• **Just do it** -- Start coding immediately

({n} files to change, familiar patterns)

• **Plan it** -- Create implementation plan first

(~{n} tasks estimated, {n} contexts affected)

• **Research it** -- Comprehensive plan with deep research

(unfamiliar tech, need to evaluate approaches)

Replace ALL placeholders with actual data from your analysis. Skip options that don't make sense (e.g., don't offer "just do it" for security-critical features).

4. **Handle Response**:

• "just do it" → Transition to WORKING
• "plan it" → Transition to PLANNING (standard detail)
• "research it" → Transition to PLANNING (comprehensive detail,

spawns 4+ agents including web-researcher)

• "tell me more" → Loop in DISCOVERING with questions
• Security features (payment, auth) → Cannot skip to WORKING

PLANNING

1. Spawn research agents based on complexity and feature type:

• **Standard**: phoenix-patterns-analyst + 1-2 relevant specialists
• **Comprehensive**: 4+ agents including

web-researcher, hex-library-researcher, phoenix-patterns-analyst, and conditional specialists (liveview-architect, ecto-schema-designer, oban-specialist, security-analyzer)

Scope each agent prompt to the relevant directories and patterns.

2. Wait for every agent to complete — you're notified as each finishes — then read each agent's output file. Synthesizing while one is still running drops its findings. 3. Synthesize findings into structured plan with:

• Phases
• Checkbox tasks with `[Pn-Tm][annotation]` format
• Verification steps

4. Write to `.claude/plans/{slug}/plan.md` 5. Transition to WORKING

WORKING

1. Read plan file 2. Find first unchecked task 3. Route to appropriate specialist agent 4. Execute task 5. Run quick check after each task:

   mix compile --warnings-as-errors
   mix format --check-formatted

6. If pass: Mark checkbox `[x]`, log progress 7. If fail: Retry (max 3), then create blocker 8. Continue until all tasks done 9. Transition to VERIFYING

VERIFYING

**Purpose**: Full verification of all changes before review. Catches issues that per-task compile checks miss (test failures, credo violations, type errors).

1. Run full verification sequence in order, stopping on first failure:

   mix compile --warnings-as-errors
   mix format --check-formatted
   mix credo --strict
   mix test --trace

Skip Dialyzer unless this is a pre-PR cycle (too slow for inner loops).

2. **If all pass**: Log verification PASS to progress file, transition to REVIEWING 3. **If any step fails**: a. Analyze the
