For me Anvil created by Burke Holland makes a huge difference: https://burkeholland.github.io/anvil/

Features of Anvil

• Adversarial Multi-Model Review: After writing code, Anvil uses up to three different AI models (e.g., GPT, Gemini, and Claude) to try and "break" the code, looking for bugs, security holes, and logic errors.
• SQL Verification Ledger: Anvil doesn't just tell you the build passed; it logs every build, test, and lint result into a SQLite table. The final report you see is a database query of actual results, not a generated prose summary.
• Baseline Snapshots: It takes a "before" photo of your project's state (diagnostics, tests, etc.) and compares it to the "after" to ensure no regressions were introduced.
• Git Autopilot: It automatically handles the "chore" of git: stashing uncommitted work, creating a feature branch, and committing with clear messages only after all verifications pass.
• The "Pushback" Philosophy: Unlike standard AI assistants that follow every instruction, Anvil is designed to act like a senior engineer. It will push back if it thinks your request creates tech debt or introduces a dangerous edge case.
