**LoopX acts as a provider-neutral, local-first control plane that gives long-running AI agents durable, auditable state across multiple turns through a compact kernel tracking objectives, gates, todos, evidence, and quota.**

The **huangruiteng/loopx** repository implements a lightweight, standard-library-only runtime that attaches to any AI environment—from Codex CLI to Claude Code—to maintain continuous context across days or weeks of work. Unlike ephemeral chat sessions, LoopX persists the lifecycle of complex tasks through structured primitives implemented in [`loopx/quota.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/quota.py), [`loopx/todos.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/todos.py), and [`loopx/state_refresh.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/state_refresh.py).

## Core Architecture and Primitives

LoopX revolves around five core commands that drive the execution loop. These primitives are implemented across specific modules in the codebase:

- **`loopx quota should-run`** – Checks whether the registered agent has available quota and scheduler permission to act now (implemented in [`loopx/quota.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/quota.py))
- **`loopx todo claim`** – Claims ownership of the next bounded slice of work via [`loopx/todos.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/todos.py)
- **`loopx todo update`** – Writes back evidence and updates state after a turn completes (implemented in [`loopx/todos.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/todos.py))
- **`loopx refresh-state`** – Projects the next view for the runtime (e.g., Codex CLI) via [`loopx/state_refresh.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/state_refresh.py)
- **`loopx quota spend-slot`** – Persists quota consumption after a successful turn (implemented in [`loopx/quota.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/quota.py))

These commands enable six recurring patterns documented in the repository's README and capabilities docs.

## Common Use Cases for LoopX

### Multi-Day Engineering and Research Projects

When tasks span days or weeks, LoopX maintains **objectives, intermediate decisions, and evidence** in a reproducible format. The control-plane board described in the main README captures the full project lifecycle, ensuring that context survives across system restarts or runtime changes. This pattern appears in the Auto-Research showcase, where proposer, executor, and evaluator agents iterate on K-NN experiments while the loop surface displays todos, quota, and evidence.

### Issue and Pull Request Loop Management

LoopX records the complete lifecycle of software changes—from initial objective through gates to todos and final evidence. This pattern, referred to as "Issue-Fix capability" in the documentation, ensures that long-running PR reviews retain full context even when distributed across multiple contributors or AI agents. The state transitions are documented in [`docs/capabilities/issue-fix/README.md`](https://github.com/huangruiteng/loopx/blob/main/docs/capabilities/issue-fix/README.md).

### Recurring Heartbeat and Monitor Workflows

Scheduled monitoring tasks (e.g., "watch this metric every hour") execute as **bounded todos** that the kernel runs only when `quota should-run` permits. This prevents runaway execution while maintaining persistent awareness of recurring obligations. The heartbeat automation prompt referenced in the README demonstrates how LoopX handles temporal constraints without external cron dependencies.

### Projects with Safety Gates and Owner Boundaries

LoopX implements **gates** that expose concrete user judgments (such as "approve this change") while maintaining safe fallbacks when a gate blocks a lane. This use case appears in workflows handling private data or requiring human-in-the-loop approval, where the gate model in the Capabilities table defines concrete blocking and non-blocking checkpoints.

### Peer-Agent Teams and Ownership Handoffs

The **claim/lease mechanism** in [`loopx/todos.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/todos.py) enables multiple agents to coordinate without requiring a single durable leader. Agents claim ownership of specific slices, execute bounded turns, and update evidence, allowing seamless handoffs between Claude, Codex, and custom shells. The "Peer agents" section of the README describes this coordination pattern for distributed agent teams.

### Legible Creator and Operations Workflows

Long-running experiments in AutoML or research contexts keep **hypotheses, evidence, and promotion decisions** in a single navigable graph. The Office-Operations connector example demonstrates how value-connectors sync with external services while maintaining LoopX's audit trail, ensuring operational workflows remain transparent and reproducible.

## Practical Workflow Implementation

The following sequence demonstrates a typical LoopX workflow from initialization through completion. All commands execute from a connected project directory:

```bash

# 1️⃣ Initialise a new long-running goal (guided)

loopx start-goal --guided --project . --goal-text "Run a multi-day benchmark suite"

# 2️⃣ Diagnose the current state and view the objective

loopx doctor
loopx status

# 3️⃣ Decide whether the loop may run now (quota check)

loopx quota should-run   # Returns true/false plus scheduler hint

# 4️⃣ Claim the next todo (agent ownership)

loopx todo claim          # Reserves the slice for current agent

# 5️⃣ Execute a bounded turn (example: run a script)

python scripts/benchmark_run_status_snapshot.py

# 6️⃣ Update the todo with evidence (automatically captured)

loopx todo update

# 7️⃣ Spend the quota after a successful turn

loopx quota spend-slot

```

For custom runners, the `run_turn` helper in [`loopx/runtime.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/runtime.py) orchestrates this sequence programmatically, directly invoking the quota, todo, and state refresh APIs.

## Summary

LoopX addresses the state management gap in long-running AI agent workflows through:

- **Durable state primitives** (objective, gates, todos, evidence, quota) implemented in standard Python
- **Runtime-agnostic attachment** working with Codex App, Codex CLI, Claude Code, or custom shells
- **Distributed coordination** via claim/lease mechanisms for multi-agent teams
- **Safety and auditability** through explicit gates and evidence persistence
- **Recurring execution patterns** via quota-gated scheduling

The architecture suits multi-day engineering projects, issue lifecycle management, monitoring workflows, and research experiments requiring reproducible state across many execution turns.

## Frequently Asked Questions

### How does LoopX differ from simple checkpointing or chat history?

LoopX implements a **structured control plane** with explicit primitives (objectives, gates, todos) rather than raw message logs. According to the source code in [`loopx/todos.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/todos.py) and [`loopx/quota.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/quota.py), it enforces bounded turns with ownership claims and quota enforcement, creating an auditable graph of decisions rather than a linear conversation history.

### Can LoopX work with multiple AI providers simultaneously?

Yes. The repository demonstrates **cross-runtime implementation reviews** where Claude implements features while Codex reviews them. Because LoopX is provider-neutral and local-first, it captures ownership, evidence, and quota across any combination of runtimes that can execute shell commands.

### What happens when a gate blocks progress in a workflow?

The gate model documented in the Capabilities table provides **safe fallbacks** when user approval is required. If `loopx quota should-run` returns false or a gate requires intervention, the loop pauses while maintaining state, allowing resumption once the gate condition clears—either through manual approval or automated satisfaction of the blocking criteria.

### Is LoopX suitable for production automated monitoring?

Yes. The **heartbeat automation** pattern shows LoopX handling recurring monitoring tasks where `quota should-run` acts as a temporal gate. Since it requires only the standard library and local state, it serves as a lightweight, auditable coordinator for scheduled operations without external infrastructure dependencies.
