Automated scan · human-rated AI repair

fix.

AST-guided repository audit — free and fully automated. The repair is done by human engineers, armed with AI agent teams.

fix is human-rated AI: the audit (syntax-aware indexing, dependency graph, price estimate) runs automatically and costs nothing. When you confirm the deposit, our engineers take over — they direct isolated AI agent sessions, review every change, and prove the result with real E2E suites before anything is committed.

Under the hood

How it works — technical details
  • AST-aware indexing: tree-sitter parses JS/TS/Swift and splits code strictly on syntax boundaries (classes, functions, hooks) up to 100 lines — no naive character splitting, no token-heavy greps.
    parse("repo"); split(syntax) 412 chunks · 618 edges
  • Graph dependencies: millisecond dependency queries give agents exact call hierarchies and edge risk flags (unhandled async promises, missing ESM extensions, UI/logic monoliths).
    query("deps") risk: unhandled_promise
  • Multi-agent tmux ADE: isolated Developer, Tester, and Orchestrator sessions coordinate over stdin/tmux pipe-pane; the Tester runs E2E suites blind, reporting only pass/fail to prevent prompt contamination.
    spawn("agent-team") dev + tester + orch
  • Payment-gated human repair: a 50% pre-payment confirmation creates an isolated git worktree and starts the repair session — our engineers drive the AI agents, review every change, and deliver a clean, test-verified PR.
