Stop silent API breakage before it reaches production.
MY OWL detects breaking API and SDK changes, traces affected code through AST analysis, plans deterministic migrations, verifies the resulting code, and opens a GitHub Draft PR for human review.
THE REAL ENGINEERING PROBLEM
An API change is only the beginning.
When a vendor announces a breaking change or deprecates a parameter, the announcement itself solves nothing. The engineering team is left with an urgent investigation across dozens of repositories.
Which repositories are affected?
Package manifests show installed dependencies and pinned versions, but cannot confirm if the deprecated method is part of an active execution path.
Which call sites actually break?
Text search creates endless false positives from comments, mocks, and unrelated variables. Only compiler-grade Abstract Syntax Tree (AST) analysis isolates the true call sites.
What is the smallest safe migration?
Translating vendor prose into a minimal, syntax-safe patch without touching untouched logic or introducing subtle regressions into production.
THE WORKFLOW
From upstream change to reviewed code.
Vendor changelog parsed

MY OWL detects breaking changes in your dependencies and finds exactly where they impact your code.

From an upstream breaking change to a verified GitHub Draft PR.
See the deterministic migration engine in action.
From upstream API deprecation to AST call-site isolation, verification, and a Draft PR.
Watch the complete workflow on a real repository.
DEPENDENCY ≠ USAGE
Dependency presence is not the same as affected usage.
Having Stripe in your package.json does not mean the deprecated parameter is used.
MY OWL parses your TypeScript and JavaScript source files into an Abstract Syntax Tree using ts-morph. It traces variable bindings and inspects argument object literals to verify whether your code actually touches a modified signature.
DETERMINISTIC CODEGEN. NOT GENERATED GUESSWORK.
Predictable AST transformations.
MY OWL does not prompt an LLM to guess what your code should look like. It applies validated, rule-driven code transforms against your exact source baseline.
VERIFICATION BOUNDARY
Nothing reaches the Draft PR without verification.
Every proposed patch must pass compiler and test verification before a branch is pushed.
