Remove the one-consumer bounded-read primitive and shared terminal lifecycle controller, make terminal cleanup one awaited provider operation, and reuse one Code Runtime contract suite. Keep only reproduced cancellation and policy fixes; defer unproven replacement, prompt-attribution, and streaming-frame concerns to scoped markers.
pty/ — persistent PTY capability family
English | 中文
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 (@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.
