Making complex codebases auditable and outage-free

Lyaris pairs AST analysis with the Claude API to audit multi-file pull requests, catch race conditions, and synthesize reproducible test suites before code hits production.

How it works

Two systems, one shared intelligence layer

Deterministic AST code traversal joined with Claude-powered semantic reasoning across your whole repository.

System 01

Semantic PR Analysis Engine

Ingests changed files alongside downstream API contracts, database migrations, and schema definitions to detect silent breaking changes before merge.

System 02

Automated Test Synthesizer

Transforms detected race conditions and edge invariants into executable Vitest and PyTest suites that reliably reproduce issues in CI before code merges.

Capabilities

Inspect, verify, & prove code invariants before merge

Every pull request traverses an exhaustive multi-repository graph. Lyaris uncovers architectural decay, unhandled async states, and invariant breaches deterministically.

  • AST Schema Analysis

    Static syntax tree traversal cross-verifies database schemas and client types across repo boundaries.

  • Race Condition Sentinel

    Flags concurrent access on shared resources, un-mutexed transactions, and async callback traps.

  • Invariant Prover

    Formally verifies system safety contracts and generates reproducible test assertions automatically.

  • Zero-Retention Isolation

    Zero-storage ephemeral runtime: customer code is parsed in memory and flushed immediately upon completion.

Lyaris Agents

Autonomous agents that audit, verify, & protect

Continuous background intelligence that watches every pull request, commits review notes directly to GitHub, and enforces architectural invariants.

Architecture Governance Agent

Contract Integrity & Dependency Graph

Maintains an immutable dependency map across all internal repositories. Any breaking API drift or schema divergence across microservices is prevented before deployment.
