Autonomous Refactoring

From breaking changes
to merged PRs —
zero hallucinations.

Tools like Dependabot only bump version numbers in configuration files. ApiPatch understands actual code semantics, validates changes through AST syntax trees, and submits ready-to-merge Pull Requests.

  • DocHunter™ Grounding: Resolves live PyPI/npm documentation and changelogs before writing code.
  • AST Verification & Compile Guarantee: Deterministically verifies that generated code compiles and runs error-free before PR creation.
  • Target Runtime & CI/CD Safe: Respects repository build matrices, Dockerfiles, and runtime pins without breaking builds.
  • Atomic GitHub Commits: Opens live PRs directly on target repositories via Git Database REST API.

Under The Hood

Engineered for real-world production codebases.

Zero guesswork. Grounded in live documentation, secured by AST compilers, and delivered via atomic Git commits.

DocHunter™ Live Grounding

Instantly pulls live official documentation, changelogs, and migration guides from PyPI, npm, and GitHub APIs in under 100ms to eliminate hallucinations.

AST Verification & Compile Guarantee

Parses refactored Python and JavaScript/TypeScript through deterministic AST linters. Guarantees code compiles and runs error-free with zero broken imports or structural regressions.

Target Runtime & CI/CD Matrix Awareness

Inspects GitHub Actions matrices, pyproject.toml, package.json engines, and Dockerfile to strictly guarantee refactorings never violate pinned runtime targets or break client CI builds.

Autonomous GitHub PR Pipeline

Run apipatch pr owner/repo to audit remote repositories, fork, create isolated branches, commit refactorings, and open live PRs automatically.

10x Parallel Async Auditing

Multi-threaded candidate file pre-filtering scans thousands of files concurrently using lightweight fast AST regex parsers before invoking the LLM.

Multi-LLM Engine & Webhook Daemon

Optimized for Google Gemini 2.5 Flash Lite, Claude 3.7 Sonnet, and GPT-4o with automatic fallback. Deploy with apipatch webhook for continuous 24/7 CI dependency monitoring.

Command Line Interface

One command to audit.
One command to patch.

ApiPatch provides intuitive CLI commands for local audits, proactive repository discovery, and autonomous pull requests.
