# Jixu Documentation

- [Introduction](/docs): A durable single-Agent Harness for TypeScript.
- [Quick start](/docs/quick-start): Install Jixu, open the TUI, or create your first Harness in TypeScript.

- **Foundations**
- [Core model](/docs/core-model): The small set of concepts that define Jixu.
- [Execution model](/docs/execution-model): How Jixu turns durable facts into explicit external work and durable outcomes.
- [Threads](/docs/threads): Create, continue, pause, interrupt, inspect, and clear one durable Agent history.

- **Continuity**
- [Recovery, Replay, and Fork](/docs/recovery-replay-fork): Three different operations for continuity, inspection, and branching.
- [Context continuity](/docs/context): Compile a bounded working set without turning provider context into durable authority.

- **Packages**
- Packages
  - [Packages](/docs/packages): Compose Jixu from independently installable runtime, adapter, Tool, and testing packages.
  - [jixu-ai](/docs/packages/jixu-ai): Install the jixu command, reference TUI, and public application facade.
  - [jixu-core](/docs/packages/core): The durable single-Agent Harness, Thread API, deterministic Kernel, and adapter ports.
  - [jixu-llm](/docs/packages/llm): Provider-neutral model capability resolution and first-party LLM Drivers.
  - [jixu-store-jsonl](/docs/packages/store-jsonl): An inspectable local JSONL Store for Events, Artifacts, and Checkpoints.
  - [jixu-store-sqlite](/docs/packages/store-sqlite): A transactional local SQLite Store for Events, Artifacts, and Checkpoints.
  - [jixu-tools-node](/docs/packages/tools-node): Opt-in file and local shell Tools with explicit workspace and process boundaries.
  - [jixu-tools-jina](/docs/packages/tools-jina): Bounded Web Search and URL Reader Tools backed by Jina.
  - [jixu-testkit](/docs/packages/testkit): Deterministic fixtures and the shared EventStore contract suite.

- **Next**
- [Coming next](/docs/coming-next): Near-term capability areas, their intended boundaries, and what is not available yet.

- **Reference**
- [Tools and safety](/docs/tools-and-safety): Permission, scope, durable approval, and the limits Jixu states explicitly.
- [Framework setup](/docs/framework): Define an Agent, bind Drivers and a Store, then create a durable Thread.
- [Reference TUI](/docs/cli): Operate durable Threads from the native Jixu terminal interface.
- [Guarantees and boundaries](/docs/guarantees): What Jixu commits to, and where it deliberately stops.
