LoopFlow automates Claude Code with YAML-defined agent loops and verification gates.

LoopFlow addresses common limitations in unattended agent workflows by enforcing a distinct reviewer persona that must output an explicit pass verdict, applying hard USD ceilings on every iteration, and maintaining a shared Markdown memory file that is appended after each run and injected into subsequent prompts. Optional git worktree isolation further prevents concurrent loops from interfering with the main working tree while every step records a resumable session identifier for later inspection. The tool runs entirely locally with no additional services or keys required beyond an existing Claude Code installation. Users initialize a project with starter loop templates for tasks such as test fixing, technical debt auditing, and documentation synchronization, then execute them directly from the command line with optional dry-run previews. Each loop step invokes Claude Code in headless mode, passing the current memory, prior outputs, and any gate feedback so the process becomes progressively more informed without manual intervention.
Define a YAML loop with a fix step that runs the test suite and diagnoses failures, followed by a separate review gate that inspects diffs and re-runs tests to confirm no weakening occurred.
Create pipelines where one agent implements changes and a skeptical reviewer agent must output a PASS verdict before the loop succeeds, using appended memory files to retain learnings across iterations.
Set max_usd and max_iterations limits in the loop definition so the system stops automatically if costs exceed the ceiling or attempts are exhausted, while logging session IDs for later resumption.

Our take: LoopFlow is a solid coding & dev choice. It's valued for eliminates self-grading by using distinct reviewer agents and enforces cost control via budgets and iteration caps. The main trade-off is requires claude code installed and authenticated. A good pick if you want capable AI without a high upfront cost.
LoopFlow is a CLI tool that lets users define goals, agent pipelines, and verification gates in a single YAML file so Claude Code runs iteratively until the gate passes or limits are reached.
