AgentLoopKit

A drop-in engineering loop for software agents.

An open-source Baseframe Labs developer tool.

Your software agent can produce a diff. AgentLoopKit helps you decide whether that work is reviewable, verifiable, and merge-ready.

It gives Codex, Claude Code, Cursor, OpenCode, Gemini CLI, GitHub Copilot CLI, and other engineering agents a local acceptance layer: task contracts, safety rules, verification evidence, review-readiness scores, PR descriptions, and reviewer handoffs.

Unstructured automation produces code. Agentic engineering produces auditable work.

ProjScan finds the risk. AgentLoopKit controls the work. AgentFlight proves the result.

The screenshots and terminal demos in this README are generated from committed sources in docs/assets/readme/ with Playwright and VHS. You can regenerate them locally.

What It Does

AgentLoopKit is a repo-level toolkit for developers using Codex, Claude Code, Cursor, OpenCode, Gemini CLI, GitHub Copilot CLI, and other engineering agents.

Keep your agent, IDE, and CLI. AgentLoopKit gives those tools a repeatable local workflow:

1. Specify the task.
2. Constrain the risk.
3. Implement the smallest useful change.
4. Verify with real commands.
5. Review the diff.
6. Hand off with evidence.
7. Ship only when the work is reviewable.

Run init inside an existing repository and AgentLoopKit creates:

• .agentloop/ for tasks, reports, handoffs, gates, policies, templates, and agent instructions
• AGENTS.md for agent-facing repo guidance
• AGENTLOOP.md for the working loop
• agentloop.config.json for local command and path settings

Generated AGENTS.md includes a specialist roster for product, CLI, template, verification, security, release, docs, compatibility, MCP, and repo-steward work. It helps future agent sessions split work without adding a background service.

The CLI demo shows the normal path: initialize a repo, create a task, run reviewed verification, score review readiness, draft PR copy, inspect review context, and trace why a file changed.

Install

Use it with npx from the repository you want to configure:

cd /path/to/your/repo
npx agentloopkit init --dry-run
npx agentloopkit init

init writes files into the current directory. --dry-run previews the same plan and writes nothing.

Commit the generated harness baseline before your first feature task when you want clean diff evidence. If the harness files are still uncommitted, explain-diff, Guard, and resume packs will include those generated files as local work, which is accurate but noisier than the steady-state loop.

After setup, non-init commands search upward for the nearest agentloop.config.json and use that folder as the AgentLoop root. You can run agentloop status, agentloop verify, agentloop ship, or agentloop prepare-pr from a nested source folder and still write tasks, reports, runs, and handoffs to the initialized repo root.

Do not run init from your home directory unless you intend to configure your home folder. AgentLoopKit refuses that by default; --force allows it and prints a home-directory target warning. If you want local agent guidance but do not want to commit the generated files, use local-only mode:
