Identify the implementation scope:
```
git diff --name-only HEAD~5
git status
```
Locate relevant specification: UPP-1.3.spec.md or related spec files
Identify affected providers/modules

Step 2: Spawn Review Sub-Agents

Delegate parallel reviews to sub-agents for:

Agent Focus	Review Scope
Spec Compliance	Compare implementation against spec requirements
Code Standards	Organizational consistency, naming, patterns
API Validation	Search web to validate API parameters, endpoints, payloads
Regression Check	Search codebase for potential breaking changes

Step 3: Synthesize Reports

Collect sub-agent findings and compile:

Compliance gaps - Missing or incorrect spec implementations
Quality issues - Code smells, inconsistencies, design concerns
API correctness - Validated against official documentation
Regression risks - Potential breaking changes identified

Output Format

# Implementation Review Report

## Summary
[One paragraph overview]

## Spec Compliance: [PASS/PARTIAL/FAIL]
- [ ] Requirement 1
- [ ] Requirement 2

## Code Quality Issues
| Severity | File | Issue | Recommendation |
|----------|------|-------|----------------|

## API Validation
[Findings from web search validation]

## Regression Risks
[Identified risks and mitigation]

## Release Readiness: [READY/BLOCKED/NEEDS WORK]
[Estimation with blockers listed]

Notes

Always validate external API usage against current documentation
Cross-reference with existing provider implementations for consistency
Flag any deviations from established patterns
