# pty/ — persistent PTY capability family
|
|
|
|
English | [中文](README.zh.md)
|
|
|
|
`PTY` stands for **Pseudo-Terminal**（伪终端）. This capability provides persistent, owner-scoped terminal sessions for workflows that require state across tool calls or interactive stdin. PTY complements the one-shot bash and filesystem tools; it does not replace their stronger per-operation contracts.

|
| Package | Role | ctx key |
|
|
|---|---|---|
|
|
| [`pty`](pty/README.md) (`@deepseek-ai/dsh-pty`) | Backend registry, branded ids, exact-Agent ownership, session operations, and awaited cleanup | `ctx.pty` |
|
|
| `pty-local` (`@deepseek-ai/dsh-pty-local`) | Shell backend over `ctx.subprocess.spawnTerminal`: readiness detection, bounded terminal state, sandbox policy, and session operations | registers on `ctx.pty` |
|
|
| `tool-pty` (`@deepseek-ai/dsh-tool-pty`) | Six model-facing tools and generic task integration for background sends | registers on `ctx.tools` |
|
|
|
|
The design and deferred boundaries live in the [persistent PTY Agent Note](../../.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.md).
