# 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): routes focused long-horizon work and never executes generated work
- [loop-graph compiler](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-graph/SKILL.md): shared executor + supervisor + ledger compile
- [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-deliver](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-deliver/SKILL.md): preset entry — requirement-delivery interview, then the same compile
- [loop-research](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-research/SKILL.md): preset entry — evidence-led solution comparison, then the same compile
- [preset contract](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-graph/docs/preset-contract.md): baseline versus goal-pack ownership
- [loop-graph model](https://github.com/levi-qiao/longgraph-skill/blob/main/skills/loop-graph/docs/model.md): node/edge invariants
