Change Planning

Analyze uncommitted git changes and understand their ripple effects through the codebase.

Quick Decision

Tool Reference

noodlbox_detect_impact

Detect which processes are affected by git changes.

noodlbox_detect_impact(
  repository: "current",
  change_scope: "all",
  include_content: false,
  max_processes: 10
)

Parameters:

• change_scope: What changes to analyze (see table above)
• base_ref: Branch/commit to compare against (for "compare" scope)
• include_content: Include symbol source code in response
• max_processes: Limit results per page

Risk Assessment

Workflow Checklist

Pre-Commit Review

Pre-Commit Checklist:
- [ ] Run impact detection (scope: staged)
- [ ] Check changed_symbols count
- [ ] Review each impacted_process
- [ ] Verify changes are intentional
- [ ] Split commit if impact > 10 processes

Code Review

Code Review Checklist:
- [ ] Run impact detection (scope: compare, base_ref: target_branch)
- [ ] Check cross-community impact
- [ ] Verify test coverage for impacted areas
- [ ] Flag high-centrality changes
- [ ] Document coordination needs

For detailed workflow guidance, see workflows.md.

Example: Pre-Commit Check

Task: "What will my changes affect before I commit?"

Step 1: Run impact detection
noodlbox_detect_impact(
  repository: "current",
  change_scope: "staged"
)

→ Summary:
  changed_symbols_count: 3
  total_impacted_processes: 7

→ Changed symbols:
  - validatePayment (src/payments/validator.ts:42) - Modified
  - PaymentError (src/payments/errors.ts:15) - Modified
  - formatAmount (src/payments/utils.ts:88) - Modified

→ Impacted processes:
  - "Checkout flow" (5 steps affected)
  - "Payment retry" (3 steps affected)
  - "Webhook handler" (2 steps affected)

Step 2: Assess risk
Changed: 3 symbols → Low
Impacted: 7 processes → Low
Cross-community: None → Low
Overall: Low risk

Step 3: Verify intentionality
All impacted processes are payment-related.
Changes are contained within the payments module.
✓ Safe to commit

Checklist for this example:

- [x] Run impact detection (scope: staged)
- [x] Check changed_symbols count (3 - low)
- [x] Review impacted processes (7 - all payment-related)
- [x] Verify changes are intentional (yes, contained)
- [ ] Split commit if needed (not needed)

Output Format

Low Impact (< 10 processes)

## Impact Summary

- **Changed**: 3 symbols in 2 files
- **Affected**: 7 processes
- **Risk**: Low

## Changed Code

| Symbol | File | Type |
|--------|------|------|
| validatePayment | src/payments/validator.ts:42 | Modified |

## Affected Flows

1. **Checkout flow** - 5 steps include changed symbols
   - Entry: `handleCheckout` → `processPayment` → `validatePayment`
   - Risk: Low (isolated change)

## Recommendations

- [ ] Run payment integration tests
- [ ] Verify checkout flow manually

High Impact (> 10 processes)
