core.md read as a type grab-bag: LLM wire vocabulary up front, the agent/loop story buried, and no correspondence to packages/core. It now opens on the packages/core control spine — the package-by-package loop map with a Page column into session/system-prompt/tools/scope — and keeps only what the spine group declares plus the repo-wide patterns: the Agent handle with its delivery/cancellation/interception contracts, the SessionEvent envelope, branded ids, the …Map pattern. The conversation vocabulary (Message/ContentBlock, the model request, adapters — 17 type-equiv blocks) moves to llm-streaming.md, which now declares packages/llm end-to-end; the duplicate ContentBlockMap paste near its seam section folds into the moved section, and the manifest, LINK_MAP, README table rows, website label (Core data structures → Core), and inbound anchors follow. Every packages/<group>/README pair is now a thin front door in one shape: a why-first intro (bash's seam-pattern-first paragraph rewritten as 'shell execution for the agent'), the package table, and a closing pointer to the owning docs/subsystems page — the bash-style table stays the load-bearing middle. Load-bearing trailing paragraphs relocate rather than vanish: the fs no-timeout rationale becomes a filesystem.md section (both languages), session's four sectioned tables merge into one 12-row table, examples' legacy-bin H2 collapses to a pointer at jsonrpc-demo's README, and design rationale that already lives in an Agent Note or subsystem page is now linked instead of restated. All 40 pair records re-recorded.

# 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).

The subsystem reference — ids, backend/session contracts, send readiness, bounded reads — is [docs/subsystems/pty.md](../../docs/subsystems/pty.md); design and deferred boundaries in the [persistent PTY Agent Note](../../.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.md).
