How to Stop Claude Code Loops in Next.js Monorepo: Fix 'Infinite recursive git-diff analysis on large directories'
what is happening
Claude Code can get trapped repeatedly inspecting large git diffs and rerunning `next build` when unresolved type errors exist in a Next.js monorepo. The loop is typically caused by oversized repository context, recursive diff analysis, and agents attempting to validate fixes by rebuilding indefinitely. Reducing the analysis scope, excluding unnecessary directories, and enforcing retry and token limits prevents runaway loops while making debugging deterministic.
manual fix
Limit Claude Code to the affected workspace, ignore generated and dependency folders, fix the root TypeScript error before triggering another full build, and cap automatic retries. If the agent continues repeating the same git-diff or `next build` cycle without making progress, stop execution, reset the context, and restart with a narrower task scope.
capping calls & killing loops automatically
if you want to prevent runaway background processes from burning through API credits, you can set budget caps and loop limits directly in terminal using guardrail.
