Product Updates & Engine Changelog
Continuous improvements to AST matching, vendor API catalogs, verification gates, and GitHub App integrations.
Deterministic AST Matching Engine v2.4
We have upgraded our core Abstract Syntax Tree parser with sub-millisecond symbol resolution, parameter-level schema diffing, and support for complex TypeScript call-site expressions.
- Sub-millisecond AST symbol resolution across multi-package monorepos
- Parameter rename tracing for object-pattern destructured argument signatures
- Full support for TypeScript 5.4 import attributes and path mapping
- Zero false positives on unused or type-only third-party imports
Available immediately across all connected GitHub repositories.
Four-Gate Migration Verification Pipeline
Every automated migration plan now executes through a strict 4-gate safety harness before any draft PR is created, ensuring proposed diffs never violate syntax, types, or tests.
- Gate 1: In-memory AST syntactic validity and indentation consistency check
- Gate 2: TypeScript compiler diagnostic check ensuring zero type regressions
- Gate 3: Call-site scope boundary verification ensuring isolated diffs
- Gate 4: Isolated container dry-run test harness validation
Protects repositories against unsafe hallucinations and unexpected regressions.
GitHub App Granular Permissions & Webhook Scans
Our GitHub App integration now operates with strict least-privilege permissions: read-only repository tree access for AST analysis and write access strictly isolated to apiproof/* branches.
- Read-only code inspection with zero persistent repository code retention
- Automatic scan triggers on dependency lockfile and package.json commits
- Instant draft PR creation with full diagnostic diffs and confidence scoring
- Seamless repository selector supporting multi-repository organizations
Enhanced security controls for organizations with strict compliance requirements.
Expanded Vendor Catalogs: Stripe v18 & OpenAI v4.0
Added comprehensive breaking change catalogs for major vendor SDK releases, including Stripe's coupon-to-discounts migration and OpenAI's structured tool calling changes.
- Automated breaking change rule ingestion from vendor release notes and SDK changelogs
- Stripe coupon → discounts[] subscription migration rule
- OpenAI completion-to-chatCompletions migration rule catalog
- Supabase auth helper deprecation and SSR cookie refactoring rules
Monitored catalogs now cover over 50 vendor SDKs and API schemas.
