Claude-Pipeline: Command for Claude Code

Verify plan-design alignment before build.

---

Prerequisites

Check that both design and plan exist:

SESSION_DIR=$(cat .claude/artifacts/current.txt 2>/dev/null)
if [ -z "$SESSION_DIR" ]; then
  echo "ERROR: No active session. Run /arm first."
  exit 1
fi
if [ ! -f "$SESSION_DIR/design.md" ]; then
  echo "ERROR: No design.md found. Run /design first."
  exit 1
fi
if [ ! -f "$SESSION_DIR/plan.md" ]; then
  echo "ERROR: No plan.md found. Run /plan first."
  exit 1
fi

Drift Detection

Use the drift-detector agent.

Input:

• Read design.md from the current session directory
• Read plan.md from the current session directory

Process:

1. Extract all design requirements:

   • Components to create
   • APIs to implement
   • Database changes
   • Behavior specifications
   • Error handling requirements

2. Map each requirement to plan step(s)

3. Check for drift types:

   • Missing Coverage: Design requirement not in plan
   • Scope Creep: Plan step not justified by design
   • Contradictions: Plan conflicts with design
   • Incomplete Steps: Plan step missing required detail

4. Output drift-report.md

Verdict Rules

ALIGNED if:

• All design requirements covered
• No unjustified scope creep
• No contradictions
• All steps complete

DRIFT_DETECTED if:

• Any requirement uncovered
• Unjustified scope creep
• Any contradiction
• Critical incomplete step

---

Output

After detection, report:

## Drift Detection Complete

**Session:** {session-directory}
**Verdict:** [ALIGNED | DRIFT_DETECTED]

### Coverage
- Design requirements: [N]
- Covered by plan: [N]
- Missing: [N]

### Issues Found
[List any drift issues]

### Next Step
[If ALIGNED] Run `/build` to implement the plan.
[If DRIFT_DETECTED] Fix the drift issues:
- Missing coverage: Update /plan
- Scope creep: Justify or remove
- Contradictions: Resolve which is correct

User Override

If drift is detected but the user wants to proceed anyway:
