438 Task 33 Workflow Enforcement Af2ecdf3

TASK-33: Workflow Enforcement Mechanism

Status: ✅ Completed Created: 2025-01-22 Version: 5.9.0 Priority: CRITICAL

Context

Problem: Navigator has comprehensive workflow documentation (Task Mode, Loop Mode, autonomous completion) but zero enforcement. Claude can ignore all of it.

Evidence:

• User said "do all it's needed" (Loop Mode trigger) → I ignored it
• Task was substantial (complexity > 0.5) → No Task Mode activated
• NAVIGATOR_STATUS blocks never shown
• Workflow completely bypassed

Root Cause:

Layer 1: Documentation (CLAUDE.md, SKILL.md)     ✓ EXISTS
Layer 2: Configuration (.nav-config.json)         ✓ EXISTS
Layer 3: Enforcement mechanism                    ✗ MISSING

Goal: Make workflow enforcement automatic, not voluntary.

Success Criteria:

• Trigger phrases ("run until done", "do all it's needed") auto-invoke Loop Mode
• Substantial tasks auto-trigger Task Mode complexity check
• NAVIGATOR_STATUS blocks shown when Loop Mode active
• Workflow compliance is validated, not hoped for

Implementation Options

Option A: CLAUDE.md Enforcement Section (Simplest)

Add to CLAUDE.md a hard requirement section that's read at session start:

## WORKFLOW ENFORCEMENT (MANDATORY)

Before responding to ANY task request, you MUST:

1. **Check for Loop Mode triggers**:
   - "run until done", "do all it's needed", "keep going", "iterate until"
   - If found → Invoke nav-loop skill, show NAVIGATOR_STATUS

2. **Check task complexity**:
   - Multi-file changes, refactoring, new features → complexity > 0.5
   - If substantial → Invoke nav-task-mode, show phase tracking

3. **Never skip these checks**
   - This is NOT optional
   - Failure to follow = workflow violation

Pros: Simple, no code changes Cons: Still relies on Claude reading and following

Option B: nav-start Enforcement Gate

Modify nav-start to install an "enforcement context" that Claude must follow:

# In nav-start session output, add:
"""
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WORKFLOW ENFORCEMENT ACTIVE

Before responding to tasks, CHECK:
□ Loop trigger? → nav-loop
□ Substantial? → nav-task-mode
□ Neither? → Direct execution OK

Show this check in your response.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
"""

Pros: Shown every session, hard to miss Cons: Adds tokens, still voluntary

Option C: Skill Auto-Invocation via Plugin Hooks (Best)

Use Claude Code's hook system to intercept user messages:

// .claude/settings.json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": ".*",
        "hooks": [{
          "type": "command",
          "command": "python3 workflow_enforcer.py \"$USER_MESSAGE\""
        }]
      }
    ]
  }
}

workflow_enforcer.py:

def check_workflow(user_message):
    # Check Loop Mode triggers
    loop_triggers = ["run until done", "do all it's needed", "keep going", "iterate until"]
    if any(trigger in user_message.lower() for trigger in loop_triggers):
        return {"action": "invoke_skill", "skill": "nav-loop"}

    # Check complexity indicators
    complexity_indicators = ["refactor", "implement", "add feature", "fix all", "update all"]
    if any(ind in user_message.lower() for ind in complexity_indicators):
        return {"action": "invoke_skill", "skill": "nav-task-mode"}

    return {"action": "proceed"}

Pros: Automatic, no Claude cooperation needed Cons: Requires hook support, adds latency

Option D: Mandatory Workflow Block in Response (Pragmatic)

Require Claude to show a workflow decision block at the start of every task response:

Add to CLAUDE.md:

Every task response MUST start with:

┌─────────────────────────────────────┐
│ WORKFLOW CHECK                      │
├─────────────────────────────────────┤
│ Loop trigger: [YES/NO] → [action]   │
│ Complexity: [0.X] → [action]        │
│ Mode: [LOOP/TASK/DIRECT]            │
└─────────────────────────────────────┘

If you don't show this block, you're violating workflow.

Pros: Visible enforcement, self-documenting Cons: Adds tokens to every response

Recommended Approach

Phase 1: Option D (Mandatory Workflow Block)

• Immediate, no code changes
• Forces visible compliance
• Easy to verify

Phase 2: Option A (CLAUDE.md Enforcement Section)

• Reinforce in documentation
• Add to Forbidden Actions

Phase 3: Option C (Plugin Hooks)

• Long-term automation
• Remove reliance on Claude cooperation

Implementation Plan

Phase 1: Mandatory Workflow Block

Tasks:

• Add WORKFLOW CHECK requirement to CLAUDE.md
• Add workflow violation to Forbidden Actions
• Update nav-start to remind about workflow check

Files:

• CLAUDE.md - Add enforcement section
• skills/nav-start/SKILL.md - Add reminder in session output

Phase 2: Trigger Detection

Tasks:

• Create workflow_detector.py with trigger phrase matching
• Create complexity_scorer.py for quick complexity assessment
• Integrate into nav-start session initialization

Files:

• skills/nav-start/functions/workflow_detector.py (new)
• skills/nav-start/functions/complexity_scorer.py (new)
• skills/nav-start/SKILL.md - Call detector on start

Phase 3: Hook-Based Enforcement (Future)

Tasks:

• Investigate Claude Code hook capabilities
• Create PreToolUse hook for workflow enforcement
• Test latency impact

Files:

• .claude/settings.json - Add hooks
• hooks/workflow_enforcer.py (new)

Technical Decisions

Verify

# Test trigger detection
echo "run until done: fix the bug" | python3 workflow_detector.py
# Expected: {"loop_mode": true, "trigger": "run until done"}

# Test complexity scoring
echo "refactor auth to use JWT" | python3 complexity_scorer.py
# Expected: {"score": 0.8, "task_mode": true}

Done

• WORKFLOW CHECK block required in CLAUDE.md
• Workflow violation added to Forbidden Actions
• nav-start shows enforcement reminder
• Trigger phrases are detected (manual or automated)
• Claude actually follows the workflow (tested)

Anti-Patterns to Prevent

1. Direct response without check - Claude just answers without workflow evaluation
2. Ignoring trigger phrases - "do all it's needed" bypassed
3. Skipping complexity assessment - Substantial tasks done ad-hoc
4. Missing NAVIGATOR_STATUS - Loop Mode active but no status blocks
