# re0-loop

Drives repeated development loops through vertical slices, real-surface checks, and memo-based learning. Keeps projects focused on verified modules rather than code volume.

## What it does

\`re0-loop` guides an agent through a disciplined turn: FRAME, BUILD, DRIVE, RE0-MEMO, HATE, and RE0-WORK. Progress is measured by quality-cleared templates and eliminated anti-patterns, not accumulated files. The agent first establishes a thesis, then builds a single vertical slice. Unit tests serve as supporting proof, but real-surface validation is mandatory. For web projects this means a browser run, while APIs require real HTTP requests.

At the end of the pass, `re0-memo` captures lessons and next-cycle gates. When the next action is uncertain, `nba` reads the state and returns one specific step. An adversarial review skill or human attack must challenge the upcoming plan before building restarts. Only cleared modules receive version labels. A restart that retains key lessons counts as forward motion, so unverified code is allowed to die.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-loop -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/re0-loop/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/re0-loop/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-loop -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/re0-loop/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-loop -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/re0-loop/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install LilMGenius/paperthin re0-loop
```

2. **Manually: put the files in place**
- File: `.github/skills/re0-loop/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-loop -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/LilMGenius/paperthin --path skills/coil/re0-loop
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/re0-loop/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add LilMGenius/paperthin --skill re0-loop -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- enforce agent progress via vertical slices and real-surface verification
- record anti-patterns and rules between cycles using `re0-memo`
- challenge new plans before building through adversarial review
- prevent unverified modules from receiving version labels

## Example prompts
- Run re0-loop for the first vertical slice of our API.
- Execute the DRIVE step in a browser and verify the slice.
- Run re0-memo to record anti-patterns before planning the next lap.

name: re0-loop
description: "Run repeated build -> QA -> re0-memo -> re0-work cycles while preserving learning and letting code die. Use for long agentic projects where progress must be measured by quality-cleared templates, reusable modules, and eliminated anti-patterns rather than hours spent or features accumulated."
---

Run the cycle so learning compounds and code accumulation does not masquerade as progress.

## Goal

`re0-loop` keeps a project moving through repeated turns:

```text
FRAME -> BUILD -> DRIVE -> RE0-MEMO -> HATE -> RE0-WORK -> BUILD AGAIN
```

The unit of progress is not hours, files, panels, or features. It is the count of quality-cleared templates, reusable platform modules, and anti-patterns eliminated in later cycles.

## Workflow

1. Frame the thesis and quality gates.
2. Build one complete vertical slice.
3. Drive it through the real surface: browser for web apps, HTTP for API contracts, computer-use for desktop apps, and CLI only for data-shaped artifacts.
4. Run `re0-memo` to extract lessons, anti-patterns, and next-cycle gates.
5. Decide whether the next pass iterates in place or uses `re0-work`; when that call or the next move is unclear, `nba` reads the cycle state and returns the single next action.
6. Kill the next plan before build: use the project's adversarial review skill or a human-invoked attack when that skill is user-only.
7. Version only templates or modules that clear their gates.

## Rules

- Tests are supporting evidence, not the gate; every turn needs a real-surface proof sized to the artifact.
- Do not widen before the core loop clears.
- Do not confuse generated variety with structural variety. If many outputs converge to the same shape, the cycle failed the variety gate.
- Preserve negative corpus so later cycles can prove the same anti-pattern is gone.
- Let code die. A restart that preserves the right lessons is progress.
- Stop a lap when no outside truth enters; add evidence before another internal pass.

## Verification

Before finishing a lap:

1. The real surface was driven and evidence was captured.
2. The re0-memo names at least one lesson, anti-pattern, or gate that affects the next pass.
3. The keep/iterate/re0-work decision is explicit.
4. Any version label belongs only to a quality-cleared template or module.
