Trace cross-file regressions, audit library migrations, and generate verified codemods directly from repository diffs using Anthropic's extended context models.
Inspect multi-file diffs in real time. Switch migration presets or simulate an active Claude Sonnet 5.5 audit run.
Designed specifically for complex monorepos, continuous upgrades, and large-scale architectural refactors.
Scans symbol dependencies and call graphs across full monorepos to evaluate side effects. Traces hidden runtime failures before they propagate into production build steps.
Emits ready-to-merge unified git patch files (.patch) for detected breaking changes. Apply instantly with git apply or branch via CI bot.
Runs AST parsers locally on your developer machine. Only minimal semantic diff context is routed through Claude's Zero-Data-Retention API. Code is never stored or trained on.
Processes thousands of lines of TypeScript definitions, Prisma schemas, and Next.js router boundaries simultaneously to uncover subtle contract drifts.
Filters out cosmetic whitespace, re-indentations, and comment changes. Only true semantic AST modifications and exported signature alterations trigger alerts.
Drop one GitHub Action into .github/workflows. Automatically posts inline review comments on breaking PR lines with patch suggestion blocks.
Run tracespec audit directly against local commits or staging branches. TraceSpec parses AST deltas, streams diff tokens to Claude Sonnet 5.5, and outputs actionable patches.
