# longgraph-skill

> Long-horizon agent skill for Claude Code, Cursor, Codex, and Grok Build.

> Durable ledger + clean-context supervisor + verified gates. Queue many long tasks

> (related or not) in one loop; switch hosts mid-run by re-sending the frozen prompt

> against the same files. Markdown prompt library, not an orchestration framework.

## Primary

- [README](https://github.com/levi-qiao/longgraph-skill/blob/main/README.md): overview, when to use, install, host compatibility

- [README (简体中文)](https://github.com/levi-qiao/longgraph-skill/blob/main/README.zh-CN.md)

- [Methodology](https://github.com/levi-qiao/longgraph-skill/blob/main/lib/methodology.md): why each constraint exists

- [Host references](https://github.com/levi-qiao/longgraph-skill/tree/main/skills/loop-graph/references): independently loaded loop/goal syntax and context model per host

## Skills (authoring → runtime)

- [Root `/longgraph`](https://github.com/levi-qiao/longgraph-skill/blob/main/SKILL.md): checks fit and delegates authoring to loop-graph; never executes generated work

- [loop-graph author](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-graph/SKILL.md): executor + supervisor + ledger

- [loop-converge](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-converge/SKILL.md): preset entry — code-convergence interview, then the same loop-graph compile

- [loop-graph model](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-graph/docs/model.md): node/edge invariants

## Install

/plugin install longgraph@longgraph-skill

```

Codex / Cursor (and local clone):

```sh

curl -fsSL https://raw.githubusercontent.com/levi-qiao/longgraph-skill/main/install.sh | sh

```
