Each `bash` foreground run starts a fresh shell, so shell-local cwd, exported variables, virtual-environment activation, functions, job-control state, and interactive child processes end with that call. + +That gap excludes workflows whose state lives in a terminal rather than a file: stepping through `gdb`, exploring in a Python or Node REPL, driving a line-oriented editor such as `ed`, or returning to a shell after interrupting its foreground command. The generic [`ctx.tasks`](../../../../packages/tasks/README.md) runtime retains background-operation handles and output, but it does not provide interactive stdin or terminal semantics. + +The existing `bash`, `read`, `write`, and `edit` tools remain the reliable default for bounded, auditable operations. A PTY is an additional capability for work that genuinely requires terminal state, not evidence that those tools are defective or candidates for removal. + +## Proposal + +Add an optional `packages/pty/` capability family that exposes agent-owned, persistent, line-oriented PTY sessions. It follows the repository's [capability pattern](../../implemented/architecture/2026-06-13-capability-seams.md), coexists with the existing command and filesystem tools, and does not change `agent-loop`. + +The first delivery supports interactive shells and line-oriented REPLs on Linux and macOS. Full-screen terminal applications, keystroke sequences, BEL-triggered control flow, session restoration after process loss, and cross-agent session sharing are explicitly deferred until the basic lifecycle is proven. + +### Package topology + +| Package | Role | ctx key | +|---|---|---| +| `dsh-pty` | `PtyService`, branded `PtySessionId`, backend registry, owner-scoped session contract, and result types | `ctx.pty` | +| `dsh-pty-local` | [`node-pty`](https://github.com/microsoft/node-pty)-based local backend, platform process inspection, bounded terminal buffer, sandbox resolution, and process-tree supervision | registers a backend on `ctx.pty` | +| `dsh-tool-pty` | Six model-facing tools, task-runtime integration for background sends, guidance, and ACP render intents | registers on `ctx.tools` | + +Idle detection is backend behavior, not a second public seam. A remote or container backend may have authoritative readiness signals that do not resemble local `/proc` inspection; every `PtyBackend` therefore returns the common send result while owning its detection mechanism internally. + +### Agent ownership and identity + +`PtyService` stores live sessions process-locally, but every session is owned by the exact `Agent` passed through the tool execution context. The service mints an opaque `PtySessionId`; an optional model-chosen `name` is display metadata and is unique only within that owner. Every operation targets `sessionId`, and `list`/`read`/`signal`/`kill` reject callers other than the owner. + +The initial design has no plugin-load auto-start sessions. `pty_spawn` creates a session only during an agent tool call, when ownership and the owning event-sourced session are known. Deployments that later need declarative startup must compose it through unpublished agent setup rather than create shared global terminals. + +Agent-scope disposal closes registrations first, then awaits quiescent teardown of every owned PTY. Backend or tool-plugin reload does not orphan sessions: ownership lives in `PtyService` until the agent ends, following the same service-owned-record pattern as [`ctx.tasks`](../../../../packages/tasks/tasks/README.md). + +### Security and process boundary + +A registered `shell` backend constrains how a terminal starts; it does not constrain commands typed after startup. `dsh-pty-local` therefore applies two protections before spawning: + +- It builds a scrubbed child environment using the same credential-shaped-name policy as `bash-local`, removing ambient `*KEY*`, `*SECRET*`, `*TOKEN*`, and harness-managed variables unless an explicit trusted mapping supplies them. +- Its `sandbox` config is `required | optional | disabled`, defaulting to `required`. `required` fails plugin load when `ctx.sandbox` is unavailable; `optional` uses the provider when present; `disabled` is an explicit unconfined opt-in. The selected provider wraps the session argv once and remains the process boundary for the PTY lifetime. + +Sandboxing confines local process effects but does not make arbitrary shell input safe: network calls and other external side effects remain governed by deployment policy. Tool descriptions state that PTY sessions are less auditable than one-shot tools and should be used only when persistence or interactive stdin is necessary. + +The implementation uses only public `node-pty` capabilities: child PID, `data` and `exit` notifications, `write`, `resize`, and `kill`. It does not assume access to the native master fd or call `waitpid` from TypeScript. Platform process inspectors derive process-group and session membership from `/proc` on Linux and `ps` on macOS. + +### Six model-facing tools + +| Tool | Purpose | Result | +|---|---|---| +| `pty_spawn` | Create an owner-scoped session from a registered backend type | `{ sessionId, name, type, motd }` | +| `pty_send` | Send text, optionally submit Enter, and wait for readiness or register a background task | bounded viewport plus wait and session status; background also returns `taskId` | +| `pty_read` | Read a bounded page from retained scrollback | `{ text, totalLines, lineBegin, lineEnd, truncated }` | +| `pty_signal` | Send one allowed signal to the current foreground process group | `{ delivered, targetPgid }` | +| `pty_kill` | Close one session and await process-tree quiescence | `{ killed }` | +| `pty_list` | List the caller's live sessions | owner-scoped session summaries | + +`pty_send({ sessionId, text, submit?, background? })` treats `text` as UTF-8 bytes and resolves `submit` to `true` in the tool implementation. When `submit` is true it writes the platform Enter sequence after the text; when false it writes only the text, allowing control characters and REPL fragments without hidden content heuristics. + +Foreground sends return a bounded rendered delta and two independent facts: `waitReason` (`stdin_read | inferred_idle | timeout | session_exit`) and `sessionStatus` (`running` or `exited` with exit code or signal). `session_exit` refers to the PTY's top-level shell process, not an arbitrary foreground command whose status the shell consumes. A timeout never implies process exit. + +With `background: true`, `dsh-tool-pty` registers the in-flight send on `ctx.tasks` and returns immediately with `taskId`. `task_output(wait: true)` waits, reads incremental output, and records the final result; `task_kill` forwards cancellation as `SIGINT` and escalates only through the PTY backend's owned teardown path. If the task surface is absent, background mode fails before writing input. No PTY-specific `sleep` tool or general wake-up seam is added. + +`pty_read` pages backward from the newest retained line. The backend enforces both line and UTF-8 byte caps on retained scrollback and the complete returned value, so one oversized line cannot bypass the bound. `truncated` distinguishes retention loss from an ordinary viewport delta. + +`pty_signal` accepts the closed set `SIGINT | SIGTERM | SIGKILL | SIGTSTP | SIGHUP`. The backend resolves the terminal foreground process group at execution time. `SIGKILL` is rejected when that group is the top-level shell, directing the caller to `pty_kill`; a failed group lookup fails the operation instead of signaling a guessed PID. + +### Local readiness detection + +The local backend runs three bounded tiers. All timings are validated config fields: `pollIntervalMs`, `exactProbeAfterMs`, `idleSilenceMs`, and `timeoutMs`. + +On Linux, the inspector reads the shell's terminal foreground PGID from `/proc//stat`, enumerates every process and thread in that process group, and probes their current syscalls. A positive Tier 1 result requires an observed stdin wait: direct `read(0)`, a permitted read of a `select`/`pselect6` or `poll`/`ppoll` argument containing fd 0, or an epoll interest list containing fd 0. Unreadable process memory and unrecognized syscalls are misses, never positive guesses. Architecture tables contain only syscall numbers defined by the corresponding Linux UAPI; unsupported architectures skip Tier 1. + +On macOS there is no exact syscall tier. Output silence returns `inferred_idle` for any foreground process group, including Python and `gdb`; `ps`-derived terminal PGID is used for signaling, not as proof that only the shell can be idle. Pure process-inspector logic is injectable and unit-tested on Linux, while a macOS CI job exercises the real PTY and process-table path. + +Tier 2 returns `inferred_idle` after `idleSilenceMs` without output. A sleeping or network-blocked command can therefore look ready. Tier 3 returns `timeout` after `timeoutMs` so a foreground tool call cannot hold the agent indefinitely. The result preserves the distinction; callers may wait through `ctx.tasks`, signal the foreground group, or inspect from another session. + +`node-pty` data notifications feed one streaming decoder and terminal parser. Parser carry state handles UTF-8 and terminal query sequences split across chunks. The first delivery normalizes line-oriented output and detects alternate-screen entry, but it does not promise correct interaction with a full-screen application. + +### Model-visible output and durability + +The existing durable `tool/call` and `tool/result` events are the source of truth for text sent by the model and rendered output returned to it. `pty_spawn` returns its MOTD through the logged tool result; foreground `send`/`read`/`list`/`signal`/`kill` results are logged the same way. The PTY packages do not duplicate raw byte streams into custom session events. + +Background sends use the existing task completion notice and `task_output` result path, so any output that reaches a later model request is likewise durable. Raw terminal bytes remain bounded process-local state and are neither persisted nor restorable. A future opt-in transcript sink would need its own retention, credential, and privacy contract. + +### Process-tree teardown + +The top-level `node-pty` child is treated as the POSIX session leader, but the owned resource is the complete OS process session, not one PID. On close, the backend stops callbacks, sends `SIGTERM` to all still-matching session members, closes the PTY, awaits `node-pty` exit plus process-inspector quiescence, then sends `SIGKILL` to verified survivors after configurable `disposeGraceMs`. Membership snapshots include process-start identity so PID reuse cannot redirect escalation. + +Teardown reports root exit and survivor cleanup independently. It does not claim success merely because the shell exited; disposal resolves only after no captured session member remains or returns a structured cleanup failure naming the survivors. + +### Composition and rollout + +The example composition remains opt-in and safe by default: + +```yaml +plugins: + '@deepseek-ai/dsh-sandbox-local': + '@deepseek-ai/dsh-pty': + '@deepseek-ai/dsh-pty-local': + config: + sandbox: required + scrollbackLines: 10000 + scrollbackMaxBytes: 4194304 + maxReadBytes: 262144 + pollIntervalMs: 50 + exactProbeAfterMs: 150 + idleSilenceMs: 3000 + timeoutMs: 30000 + disposeGraceMs: 3000 + '@deepseek-ai/dsh-tool-pty': +``` + +The package ships concise tool guidance explaining persistent state, owner isolation, uncertain idle results, cleanup, and the preference for existing one-shot tools when interaction is unnecessary. It does not add a global system-prompt recommendation or mount PTY in shipped defaults. + +### Deferred work + +- Full-screen TUI support, named key sequences, BEL interruption, terminal resize tools, and alternate-screen snapshots require a separately proven model-facing contract. +- Declarative per-agent startup requires an agent-setup composition point; plugin-load global sessions remain prohibited. +- Session restoration across harness-process loss requires an out-of-process owner and a versioned protocol. +- Network-egress policy and rollback of external side effects are broader than PTY and remain separate security work. +- Windows/ConPTY support requires a backend with Windows-native process ownership and signaling semantics. + +## Alternatives considered + +**Replace `bash`, filesystem tools, or task tools with PTY.** Rejected. One-shot tools retain stronger validation, approval, sandbox, output-bound, and replay contracts. PTY is reserved for interactive state. + +**Add persistent mode to `bash`.** Rejected. Returning on readiness rather than process exit, retaining a process tree across calls, and exposing interactive stdin create a different ownership and failure contract. + +**Require native master-fd access from `node-pty`.** Rejected. Its public API exposes no master fd. The local backend instead derives foreground and session membership from supported OS process metadata and treats unreadable metadata as a detector miss. + +**Publish `PtyIdleDetector` as a replaceable registry.** Rejected. Only the local backend needs these platform probes, while remote backends may receive readiness over their own protocol. Backend replacement already provides the necessary extension point. + +**Add a PTY-specific `sleep` tool.** Rejected. `ctx.tasks` already owns bounded waiting, cancellation, completion notices, and model-facing collection. A second general wake mechanism would cross the agent-loop boundary and duplicate that contract. + +**Include TUI sequences and BEL handling in the first delivery.** Rejected. The source prototype treats those paths as timing-sensitive and still records unresolved alternate-screen and interaction failures. Line-oriented PTY use proves the core value without making those unverified behaviors foundational. + +**Use an out-of-process daemon immediately.** Rejected for the initial in-process capability because current persistent front doors already keep a Cordis context alive. A daemon becomes justified by cross-process restoration or multi-client attachment, both deferred here. + +## Acceptance criteria + +- `packages/pty/{pty,pty-local,tool-pty}` build as the interface, local implementation, and model consumer; backend registrations dispose cleanly. +- Every live PTY has one service-minted `PtySessionId`, one exact `Agent` owner, owner-fenced operations, and awaited cleanup on agent disposal; concurrent agents may reuse display names without sharing state. +- `dsh-pty-local` uses only public `node-pty` APIs and contains no master-fd or TypeScript `waitpid` assumption. +- Environment tests prove credential-shaped ambient variables are absent. `sandbox: required` fails at load without a provider, and real composition proves the provider wraps the long-lived session process. +- Linux fixtures cover pipelines, a stdin-reading non-leader process, a stdin-reading non-main thread, unreadable process memory, supported UAPI syscall tables, unsupported architectures, and false-positive rejection. macOS process-inspector logic reaches 100% coverage on Linux, and macOS CI drives a real bash and Python REPL. +- Foreground tests exercise `stdin_read`, `inferred_idle`, `timeout`, and top-level session exit without treating a foreground command exit as directly observable. +- Background sends register `ctx.tasks` work, return before readiness, stream bounded output through `task_output`, honor task cancellation, and fail before writing when the task surface is absent. +- Scrollback and every model-facing result enforce final UTF-8 byte bounds, including a single oversized line and multibyte boundary cases. +- `pty_signal` resolves the live foreground group, rejects lookup failure and shell-targeted `SIGKILL`, and never falls back to a guessed PID. +- Disposal tests start foreground and background descendants, including a signal-ignoring child, then prove every captured process identity is gone immediately after awaited agent disposal. +- A test-only `cordis.yml` boots through the Loader on Linux and macOS, mounts the real local backend plus sandbox, and drives spawn/send/read/signal/kill/list through the real tool registry. ACP and headless snapshots pin the six schemas, bounded results, errors, and render intents. +- TUI, sequence, BEL, auto-start, Windows, and crash-restoration behavior are absent from the public schema and documented as deferred rather than simulated by fixtures. +- Package READMEs and JSDoc document configuration, ownership, failure, cancellation, bounds, sandboxing, model-visible effects, and limitations; `docs/architecture.md` and generated catalogs update with the implementation. +- The repository CI-equivalent sequence in root `AGENTS.md` passes, including `test:coverage`, snapshots, documentation, build, hygiene, and built-entry smokes. + +## Risks + +**Idle below Linux Tier 1 is heuristic.** Output silence cannot distinguish a prompt from sleep or network I/O. The typed result preserves uncertainty, and bounded timeout plus task waiting and signaling keep control with the model. + +**Persistent state can drift from the model's belief.** The model may forget its cwd or active REPL. Session summaries and retained output help recovery, but no prompt can make state persistence deterministic. + +**A shell can cause external side effects.** Session sandboxing and environment scrubbing reduce local exposure but do not undo pushes, API calls, or messages. Deployments that cannot tolerate those effects must omit PTY or add network policy. + +**Process loss destroys terminal state.** In-process sessions do not survive a harness crash or restart, and raw scrollback is not durable. Important work must be committed to files or another durable system. + +**`node-pty` is a native dependency.** Installation, supported Node versions, prebuild availability, and platform behavior

个面向模型的工具 + +| 工具 | 用途 | 结果 | +|---|---|---| +| `pty_spawn` | 从已注册的后端类型创建按 owner 隔离的会话 | `{ sessionId, name, type, motd }` | +| `pty_send` | 发送文本、可选提交 Enter，并等待就绪或注册一个后台任务 | 有界

`sessionStatus`（`running`，或携带退出码或信号的 `exited`）。`session_exit` 指 PTY 顶层 shell 进程退出，不指由 shell 消费状态的任意前台命令。timeout 从不意味着进程已经退出。 + +当 `background: true` 时，`dsh-tool-pty` 在 `ctx.tasks` 上注册进行中的发送，并立即返回 `taskId`。`task_output(wait: true)` 负责等待、读取增量输出并记录最终结果；`task_kill` 将取消转发为 `SIGINT`，只有 PTY 后端拥有的 teardown 路径可以升级信号。若 task 对外接口不存在，后台模式必须在写入输入前失败。设计不新增 PTY 专用的 `sleep` 工具或通用唤醒 seam。 + +`pty_read`

shell 时拒绝 `SIGKILL`，并指引调用方使用 `pty_kill`；进程组解析失败时操作直接失败，而不是向猜测的 PID 发送信号。 + +### 本地就绪检测 + +本地后端执行 3 个有界层级。所有时间参数都是经校验的配置字段：`pollIntervalMs`、`exactProbeAfterMs`、`idleSilenceMs` 和 `timeoutMs`。 + +在 Linux 上，检查器从 `/proc//stat` 读取 shell 的终端前台 PGID，枚举该进程组中的每个进程与线程，并检查它们当前的 syscall。Tier 1 只有观察到 stdin 等待才返回正结果：直接 `read(0)`、获准读取且含 fd 0 的 `select`/`pselect6` 或 `poll`/`ppoll` 参数，或者含 fd 0 的 epoll interest list。无法读取的进程内存和未识别的 syscall 都是 miss，绝不作为正向猜测。架构表只包含对应 Linux UAPI 定义的 syscall number；不支持的架构跳过 Tier 1。 + +macOS 没有精确 syscall 层。任何前台进程组输出静默都会返回 `inferred_idle`，包括 Python 和 `gdb`；从 `ps` 推导的终端 PGID

`disposeGraceMs` 后向已验证的存活者发送 `SIGKILL`。成员快照包含进程启动身份，避免 PID 复用把升级信号发给无关进程。 + +teardown 独立报告根进程退出与存活进程清理。它不会只因 shell 退出就声称成功；dispose 只有在已捕获的会话成员全部消失后才完成，否则返回结构化清理失败并列出存活者。 + +### 组合与推行 + +示例组合保持

A daemon becomes justified by cross-process restoration or multi-client attachment, both deferred here. -## Acceptance criteria +## Verification -- `packages/pty/{pty,pty-local,tool-pty}` build as the interface, local implementation, and model consumer; backend registrations dispose cleanly. -- Every live PTY has one service-minted `PtySessionId`, one exact `Agent` owner, owner-fenced operations, and awaited cleanup on agent disposal; concurrent agents may reuse display names without sharing state. -- `dsh-pty-local` uses only public `node-pty` APIs and contains no master-fd or TypeScript `waitpid` assumption. -- Environment tests prove credential-shaped ambient variables are absent. `sandbox: required` fails at load without a provider, and real composition proves the provider wraps the long-lived session process. -- Linux fixtures cover pipelines, a stdin-reading non-leader process, a stdin-reading non-main thread, unreadable process memory, supported UAPI syscall tables, unsupported architectures, and false-positive rejection. macOS process-inspector logic reaches 100% coverage on Linux, and macOS CI drives a real bash and Python REPL. -- Foreground tests exercise `stdin_read`, `inferred_idle`, `timeout`, and top-level session exit without treating a foreground command exit as directly observable. -- Background sends register `ctx.tasks` work, return before readiness, stream bounded output through `task_output`, honor task cancellation, and fail before writing when the task surface is absent. -- Scrollback and every model-facing result enforce final UTF-8 byte bounds, including a single oversized line and multibyte boundary cases. -- `pty_signal` resolves the live foreground group, rejects lookup failure and shell-targeted `SIGKILL`, and never falls back to a guessed PID. -- Disposal tests start foreground and background descendants, including a signal-ignoring child, then prove every captured process identity is gone immediately after awaited agent disposal. -- A test-only `cordis.yml` boots through the Loader on Linux and macOS, mounts the real local backend plus sandbox, and drives spawn/send/read/signal/kill/list through the real tool registry. ACP and headless snapshots pin the six schemas, bounded results, errors, and render intents. -- TUI, sequence, BEL, auto-start, Windows, and crash-restoration behavior are absent from the public schema and documented as deferred rather than simulated by fixtures. -- Package READMEs and JSDoc document configuration, ownership, failure, cancellation, bounds, sandboxing, model-visible effects, and limitations; `docs/architecture.md` and generated catalogs update with the implementation. -- The repository CI-equivalent sequence in root `AGENTS.md` passes, including `test:coverage`, snapshots, documentation, build, hygiene, and built-entry smokes. +- Per-file coverage pins owner fencing, concurrent reservations, lifecycle cleanup, readiness tiers, sanitizer carry state, UTF-8 bounds, task integration, schemas, and render intents. +- Linux process fixtures cover non-leader and non-main-thread stdin waits, unreadable process state, supported syscall tables, unsupported architectures, and false-positive rejection; macOS inspector logic is injected into the same unit suite. +- Real `node-pty` tests exercise shell state, shared sandbox policy, environment scrubbing, signals, a TERM-ignoring descendant, and immediate post-disposal quiescence on supported hosts. +- A Loader-driven `cordis.yml` test mounts the real three-package composition, while ACP and headless snapshots pin the six schemas, bounded results, error rendering, and terminal/generic cards through opt-in overlays. +- Package contracts, the architecture map, core data structures, generated catalogs, and the website API describe the same shipped surface. +- The repository CI-equivalent sequence owns type, lint, coverage, snapshot, documentation, build, hygiene, demo, and built-entry verification. -## Risks +## Consequences + +**Persistent terminal state is available without weakening one-shot tools.** Shell and REPL state can survive tool calls, while `bash`, `read`, `write`, and `edit` retain their narrower validation, approval, and replay contracts. **Idle below Linux Tier 1 is heuristic.** Output silence cannot distinguish a prompt from sleep or network I/O. The typed result preserves uncertainty, and bounded timeout plus task waiting and signaling keep control with the model. **Persistent state can drift from the model's belief.** The model may forget its cwd or active REPL. Session summaries and retained output help recovery, but no prompt can make state persistence deterministic. +**A daemonized descendant can leave the captured tree.** A process that reparents before teardown is no longer discoverable from the `node-pty` root. The implementation accepts that cleanup gap instead of risking SID-wide signals to unrelated processes. + **A shell can cause external side effects.** Session sandboxing and environment scrubbing reduce local exposure but do not undo pushes, API calls, or messages. Deployments that cannot tolerate those effects must omit PTY or add network policy. **Process loss destroys terminal state.** In-process sessions do not survive a harness crash or restart, and raw scrollback is not durable. Important work must be committed to files or another durable system. diff --git a/.agents/notes/proposed/feature/2026-07-16-persistent-pty-sessions.zh.md b/.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.zh.md similarity index 64% rename from .agents/notes/proposed/feature/2026-07-16-persistent-pty-sessions.zh.md rename to .agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.zh.md index f244992abc..7f2ee00804 100644 --- a/.agents/notes/proposed/feature/2026-07-16-persistent-pty-sessions.zh.md +++ b/.agents/notes/implemented/feature/2026-07-16-persistent-pty-sessions.zh.md @@ -1,6 +1,6 @@ # Agent Note: 持久化 PTY 会话 -Status: proposed +Status: implemented [English](2026-07-16-persistent-pty-sessions.md) | 中文 @@ -12,11 +12,11 @@ harness 可以运行前台与后台命令、编辑文件和委派工作，但无 现有 `bash`、`read`、`write` 和 `edit` 工具仍是有界、可审计操作的可靠默认选项。PTY 是对确实需要终端状态的工作的补充功能，不说明这些工具有缺陷，更不意味着要移除它们。 -## 提案 +## 决策 -新增可选的 `packages/pty/` 功能家族，向模型提供由 agent 拥有、持久化且面向行式交互的 PTY 会话。它遵循仓库的 [capability pattern](../../implemented/architecture/2026-06-13-capability-seams.md)，与现有命令和文件系统工具并存，并且不修改 `agent-loop`。 +可选的 `packages/pty/` 功能家族提供由 agent 拥有、持久化且面向行式交互的 PTY 会话。它遵循仓库的 [capability pattern](../../implemented/architecture/2026-06-13-capability-seams.md)，与现有命令和文件系统工具并存，并且不修改 `agent-loop`。 -首次交付在 Linux 和 macOS 上支持交互式 shell 与行式 REPL。全屏终端应用、按键序列、BEL 触发的控制流、进程丢失后的会话恢复以及跨 agent 共享会话都明确推迟，直到基础生命周期得到验证。 +当前实现在 Linux 和 macOS 上支持交互式 shell 与行式 REPL。全屏终端应用、按键序列、BEL 触发的控制流、进程丢失后的会话恢复以及跨 agent 共享会话都明确推迟。 ### 包拓扑 @@ -32,7 +32,7 @@ idle 检测属于后端行为，不是第二条公共 seam。远程或容器后 `PtyService` 在进程内保存活会话，但每个会话都由工具执行上下文传入的确切 `Agent` 拥有。服务铸造不透明的 `PtySessionId`；模型可选填的 `name` 只是显示元数据，仅在该 owner 内唯一。所有操作都以 `sessionId` 为目标，`list`/`read`/`signal`/`kill` 会拒绝 owner 之外的调用方。 -初始设计不提供插件加载期 auto-start 会话。`pty_spawn` 只在 agent 工具调用期间创建会话，此时所有权和所属的事件溯源会话都已确定。若部署后续需要声明式启动，必须通过尚未发布的 agent setup 组合，而不能创建全局共享终端。 +实现不提供插件加载期 auto-start 会话。`pty_spawn` 只在 agent 工具调用期间创建会话，此时所有权和所属的事件溯源会话都已确定。未来的声明式启动功能必须通过尚未发布的 agent setup 组合，而不能创建全局共享终端。 agent scope dispose 时先关闭注册，再等待全部所属 PTY 静默退出。后端或工具插件 reload 不会遗留会话：所有权持续存放在 `PtyService` 中，直到 agent 结束，与 [`ctx.tasks`](../../../../packages/tasks/tasks/README.md) 的服务持有记录模式一致。 @@ -41,11 +41,11 @@ agent scope dispose 时先关闭注册，再等待全部所属 PTY 静默退出 注册的 `shell` 后端只约束终端如何启动，不约束启动后输入的命令。因此 `dsh-pty-local` 在 spawn 前应用两层保护： - 它使用与 `bash-local` 相同的凭证形态名称策略构建清洗后的子进程环境，移除环境中的 `*KEY*`、`*SECRET*`、`*TOKEN*` 和 harness 管理的变量，除非显式的可信映射提供这些值。 -- 它的 `sandbox` 配置为 `required | optional | disabled`，默认 `required`。`required` 在缺少 `ctx.sandbox` 时于插件加载期失败；`optional` 在提供方存在时使用；`disabled` 是显式选择无约束模式。所选提供方只包装一次会话 argv，并在 PTY 的整个生命周期中充当进程边界。 +- 它要求 `ctx.sandbox` 和共享的 `ctx.sandboxPolicy`。后端在 spawn 时，以部署默认值为底折叠 owner 的有效 session mode，并只包装一次 shell argv；该 mode 与 workspace root 在 PTY 的整个生命周期中充当进程边界。`danger-full-access` 是现有的显式无约束选择，不另设 PTY 私有 bypass。 沙箱限制本地进程副作用，但不会让任意 shell 输入自动安全：网络调用和其他外部副作用仍由部署策略治理。工具描述会说明 PTY 会话比一次性工具更难审计，只应在确实需要持久状态或交互式 stdin 时使用。 -实现只使用 `node-pty` 的公共功能：子进程 PID、`data` 与 `exit` 通知、`write`、`resize` 和 `kill`。它不假设能访问原生 master fd，也不从 TypeScript 调用 `waitpid`。平台进程检查器在 Linux 上通过 `/proc`、在 macOS 上通过 `ps` 推导进程组和会话成员关系。 +实现只使用 `node-pty` 的公共功能：子进程 PID、`data` 与 `exit` 通知、`write`、`resize` 和 `kill`。它不假设能访问原生 master fd，也不从 TypeScript 调用 `waitpid`。平台进程检查器在 Linux 上通过 `/proc`、在 macOS 上通过 `ps` 推导前台进程组和父子进程身份。 ### 6 个面向模型的工具 @@ -58,11 +58,11 @@ agent scope dispose 时先关闭注册，再等待全部所属 PTY 静默退出 | `pty_kill` | 关闭一个会话并等待进程树静默退出 | `{ killed }` | | `pty_list` | 列出调用方的活会话 | 按 owner 隔离的会话摘要 | -`pty_send({ sessionId, text, submit?, background?

Mark a todo `completed` the moment it is done (do not batch completions), and allow no `in_progress` item only once all work is complete. Skip the list for trivial single-step tasks. Statuses: `pending` (not started), `in_progress` (being worked on now), `completed` (finished).", + "parameters": { + "type": "object", + "properties": { + "todos": { + "type": "array", + "description": "The COMPLETE task list, replacing any previous list.", + "items": { + "type": "object", + "properties": { + "content": { + "type": "string", + "description": "What the task is — a short imperative line." + }, + "status": { + "type": "string", + "description": "pending (not started) | in_progress (now) | completed (done).", + "enum": [ + "pending", + "in_progress", + "completed" + ] + } + }, + "required": [ + "content", + "status" + ] + } + } + }, + "required": [ + "todos" + ] + } + }, + { + "name": "workflow", + "description": "Run a JavaScript workflow script that orchestrates subagents at scale. Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const — no oneOf/pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

It starts an interactive shell under the shared `ctx.sandboxPolicy`, strips credential-shaped ambient environment variables, retains bounded line-oriented output, detects readiness, and tears down the captured process tree rooted at the `node-pty` child. + +## Plugin (`pty-local`) + +The plugin injects `pty`, `sandbox`, and `sandboxPolicy`, then registers the configured backend type (`shell`). `danger-full-access` starts the shell directly; confined modes wrap the exact shell argv through `ctx.sandbox`. The current session-level sandbox override is resolved at spawn and remains fixed for the PTY lifetime. + +Linux readiness combines a private bash prompt marker, foreground-process-group syscall inspection, silence fallback, and absolute timeout. macOS uses the prompt marker plus silence/timeout because it has no `/proc` syscall surface. Unrecognized or unreadable process state is never a positive exact-idle signal. + +## Model Experience + +### Indirect consumer + +#### What the model sees + +Nothing directly. Through `@deepseek-ai/dsh-tool-pty`, the model may receive bounded MOTD, send deltas, scrollback pages, readiness reasons, and cleanup errors. + +#### Token effect + +None until a consumer returns bounded backend output. Retained PTY scrollback is not placed in model history by this package. + +#### KV Cache effect + +No direct invalidation; the consumer owns prompts, schemas, and appended results. + +## Known Limitations and Deferred Work + +- Line-oriented output is normalized; full-screen alternate-buffer interaction is unsupported. +- Linux exact probes support x64 and arm64 UAPI tables; other architectures use prompt-marker and silence/timeout readiness. +- A descendant that daemonizes and reparents before teardown leaves the captured tree; cleanup never broadens to the launcher PID's POSIX session because that can include unrelated processes. +- Sessions do not survive harness process exit. diff --git a/packages/pty/pty-local/package.json b/packages/pty/pty-local/package.json new

mints opaque session ids, routes creation through named backends, fences every operation to the exact live `Agent`, and awaits backend quiescence when that agent or the service disposes. + +## Contract + +- Backends register one stable `type` and return an unpublished `PtyBackendSession`; failed or cancelled setup must clean partial resources. +- A successful spawn publishes one `PtySessionId`. The optional `name` is owner-local display metadata, never authority. +- One session accepts at most one live send operation. Reads and signals may observe it; another send fails until the operation settles. +- `PtySendResult.waitReason` and `sessionStatus` are independent. `session_exit` describes the top-level PTY process, not an arbitrary foreground command. +- `kill()` and disposal resolve only after the backend's captured process tree is quiescent. A cleanup failure rejects instead of claiming success. + +The seam contains no `node-pty`, sandbox, tool-schema, prompt, task, or terminal-rendering policy. Implementations own terminal mechanics; consumers own model presentation and optional background-task registration. + +## Model Experience + +### Indirect consumer + +#### What the model sees + +Nothing directly. This package registers no prompt or tool; `@deepseek-ai/dsh-tool-pty` owns visible schemas and result text. + +#### Token effect + +None directly. Live session state stays process-local until a consumer returns a bounded result. + +#### KV Cache effect + +No direct invalidation; the named consumer owns request-prefix changes. + +## Known Limitations and Deferred Work + +- Sessions are process-local and are not restored after a harness restart. +- Cross-agent sharing is intentionally absent; a future shared-session design needs a separate authority contract. diff --git a/packages/pty/pty/package.json b/packages/pty/pty/package.json new file mode 100644 index 0000000000..658a92cfb7 --- /dev/null +++ b/packages/pty/pty/package.json @@ -0,0 +1,35 @@ +{ + "name": "@deepseek-ai/dsh-pty", + "description": "Persistent PTY session seam for the DeepSeek Harness — owner-scoped ids, backend registry, interactive sends, reads, signals, and awaited cleanup", + "version": "0.0.1", + "private": true, + "type": "module", + "main": "lib/index.js", + "types": "lib/types/index.d.ts", + "exports": { + ".": { + "types": "./lib/types/index.d.ts", + "default": "./lib/index.js" + }, + "./src/*": "./src/*", + "./package.json": "./package.json" + }, + "files": [ + "lib/index.js", + "lib/types/**/*.d.ts", + "lib/types/**/*.d.ts.map", + "src" + ], + "license": "BSD-3-Clause", + "peerDependencies": { + "@deepseek-ai/dsh-agent": "^0.0.1", + "@deepseek-ai/dsh-brand": "^0.0.1", + "cordis": "^4.0.0-rc.7" + }, + "devDependencies": { + "@deepseek-ai/dsh-agent": "workspace:^", + "@deepseek-ai/dsh-brand": "workspace:^", + "@deepseek-ai/dsh-session": "workspace:^", + "cordis": "^4.0.0-rc.7" + } +} diff --git a/packages/pty/pty/src/index.ts b/packages/pty/pty/src/index.ts new file mode 100644 index 0000000000..17ddfd8721 --- /dev/null +++ b/packages/pty/pty/src/index.ts @@ -0,0 +1,356 @@ +/** + * Owner-scoped persistent PTY registry.

The harness already exposes exact session enumeration and raw event inspection, but every host independently parsing logs would duplicate compaction folding, provenance filtering, size limits, error behavior, and persistence. Encoding host markup directly into the agent message contract would also bind the core loop to one UI syntax. + +## Decision + +`@deepseek-ai/dsh-session-reference` is one context consumer service at `ctx.sessionReferences`. Hosts normalize their protocol into `SessionReferenceInput[]`, call `prepare()` before enqueue, and pass the returned contexts through the generic `SendOptions.contexts` boundary. Core agent packages know only that one queued message may carry frozen `HookContext[]`; they do not parse session URIs or read another log. + +`dsh-session:` is the canonical host-independent identifier. JSON string encoding precedes base64url so quotes, slashes, backslashes, Unicode, newlines, and every other JavaScript string value round-trip without delimiter ambiguity. TUI renders that URI inside `@[label](uri)` and ACP uses standard `resource_link`; text-only clients may use the same inline mention. Explicit Markdown mentions and resource links reject malformed URIs. Bare text becomes a reference only for a non-empty base64url-shaped payload, whose decode must still be canonical; empty or punctuation-only uses remain ordinary discussion text. + +The service uses `ctx.sessionQuery.readSurface(sessionId)`, which loads one live-preferred corpus observation, folds it with the session package's canonical surface algorithm, and returns a detached header, capture seq, and current nodes. FTS is not a dependency: v1 discovery filters only id and cwd, and future title/body search can replace the candidate layer without changing reference identity or preparation. + +## Snapshot and projection + +Preparation deduplicates in first-appearance order, rejects the target id, enforces at most three references by default, and performs all reads in parallel. It returns no partially prepared context: any read, cancellation, validation, or budget error rejects the operation before `send()` or `steer()`. A source is read before enqueue, so later source messages, compaction, deletion, or persistence replacement cannot change the target session. + +Projection retains direct-user messages and steering, completed assistant text, and checkpoint user messages carrying the canonical source exported by `dsh-compact`. That marker is part of the compaction capability contract rather than a backend package name. Projection excludes shadowed pre-compaction nodes, tools and results, reasoning, injected context, other plugin user messages, log-only records, and incomplete assistant chunks. Repeated compaction therefore exposes only the latest folded checkpoint lineage still on the current surface plus its retained tail; there is no raw/current switch and no shadow recovery. + +One aggregated context is serialized as JSON beneath a fixed untrusted-background warning. The warning tells the model not to follow instructions, permission claims, or tool requests from referenced sessions unless the current user repeats them. Tag-safe serialization emits every data `<` as the lossless JSON escape `\u003c`; source strings therefore cannot spell the surrounding XML-like tags. The same serializer drives per-reference and total byte accounting. Context metadata records source and retention facts, while the visible bytes persist through the existing `context/message` event so target replay satisfies the model-visible/log-reconstructable invariant without a new event type. + +## Message ownership + +`send()` and `steer()` snapshot content, resolved source, and contexts together as one deeply frozen lossless-JSON inbox record. A claimed ordinary message exposes its attached contexts as the default `agent/prompt-submit` additional contexts; a block writes neither user message nor contexts. The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream content and contexts unless it intentionally replaces them. Drained steering bypasses `agent/prompt-submit` and writes `steering/message` before its contexts. Late steering retains the same record when converted to queued input, while cancellation, disposal, and terminal discard drop message and contexts together. `agent/queued` reports the frozen contexts so the observation event describes the complete retained item. + +This preserves host driving semantics: TUI decides `send()` versus `steer()` from the agent state after preparation, so only its queued path dispatches UserPromptSubmit hooks; ACP continues to call `send()` once per `session/prompt`. Reference preparation is not a new steering protocol and does not create a turn by itself. + +## Host adapters + +TUI combines session candidates with the existing `@` file provider. It prepares only submissions containing structured mentions, disables duplicate submit while awaiting snapshots, restores failed input, and renders persisted session-reference context as a compact source list instead of exposing the complete JSON in the terminal. + +ACP extracts `dsh-session:` resource links and canonical inline mentions while preserving ordinary resource-link rendering. A valid reference without the optional service returns a capability-unavailable RPC error, and preparation failure occurs before the in-flight turn slot and agent send. A preparation-specific abort owner makes `session/cancel` and bridge teardown stop pending reads. Picker UI remains an ACP client responsibility. + +## Budget and retention + +The defaults cap one serialized reference at 65,536 UTF-8 bytes and the complete prompt, fixed warning included, at 196,608 bytes. Retention preserves current compact checkpoints and the newest conversation unit before dropping older non-checkpoint messages. An oversized retained text uses `dsh-retention` head/tail slicing and records exact omitted bytes; if fixed metadata and warning bytes cannot fit, preparation fails rather than silently exceeding the contract. + +## Alternatives considered + +- **Wait for SQLite FTS5** — rejected because snapshot correctness requires exact id reads and canonical surface folding, not content search. FTS improves discovery only. +- **Put mention syntax in `Agent.send()`** — rejected because it would make the core protocol parse TUI/ACP presentation and prevent typed non-text hosts from sharing the semantic layer. +- **Implement references inside TUI and ACP separately** — rejected because projection, security warning, retention, and persistence would drift across hosts. +- **Replay the raw source log or restore shadowed events** — rejected because compact defines the current model surface and may intentionally retire sensitive or expensive history. +- **Resume or fork the source** — rejected because the feature supplies read-only background for one target message, not identity or lifecycle continuity. +- **Inject at request time by rereading the source** — rejected because the reference would become nondeterministic, cancellation races could alter its bytes, and target replay would depend on external mutable state. + +## Verification + +Unit and integration coverage pins URI round-trips and text-boundary punctuation, explicit malformed references, candidate ranking, projection exclusions, backend-independent compact checkpoints, tag-safe framing, deduplication, self-reference, count limits, all-or-nothing reads, cancellation, byte retention, frozen message ownership, prompt blocking, send/steer ordering, missing capability, ordinary ACP resource links, and compact TUI rendering. A keyless TUI snapshot runs the real agent loop: the source surface replaces old user/assistant history with a compact checkpoint, the target submits a mention, and the captured model request contains the checkpoint and retained tail but not either shadowed string. + +## Consequences + +The new plugin is the stable semantic boundary and adds no persistence schema, event type, FTS dependency, source subscription, or compact shadow access. Standard TUI/ACP demo bundles mount it explicitly; custom hosts remain unchanged until they mount the service and adapt their input. Reference contexts increase target history size within configured bounds and can later be summarized by ordinary target compaction, after which the source session is irrelevant. diff --git a/.agents/notes/implemented/feature/2026-07-21-cross-session-references.zh.md b/.agents/notes/implemented/feature/2026-07-21-cross-session-references.zh.md new file mode 100644 index 0000000000..e3a93db086 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-07-21-cross-session-references.zh.md @@ -0,0 +1,58 @@ +# Agent Note: 跨会话引用 + +Status: implemented + +[English](2026-07-21-cross-session-references.md) | 中文 + +## 问题 + +TUI 与 ACP（Agent Client Protocol）用户需要把另一场对话中的相关工作带入一条新消息，但不恢复、不 fork，也不让源 transcript（文本记录）对当前会话拥有权威性。harness 已经提供准确的会话枚举与原始事件检查，但若每个宿主都独立解析日志，就会重复实现压缩（compaction）折叠、来源过滤、大小限制、错误行为和持久化。把宿主标记直接编码进 agent（智能体）消息契约，还会让核心循环绑定某一种 UI 语法。 + +## 决策 + +`@deepseek-ai/dsh-session-reference` 是注册在 `ctx.sessionReferences` 上的单一上下文消费服务。宿主先把各自的协议规范化为 `SessionReferenceInput[]`，在入队前调用 `prepare()`，再通过通用的 `SendOptions.contexts` 边界传递返回的上下文。核心 agent 包只知道一条排队消息可以携带已冻结的 `HookContext[]`；它们既不解析会话 URI，也不读取其他日志。 + +`dsh-session:` 是与宿主无关的规范标识符。系统先执行 JSON 字符串编码，再执行 base64url 编码，因此引号、正斜杠、反斜杠、Unicode、换行符以及其他任意 JavaScript 字符串值都能无损往返，不会因分隔符产生歧义。TUI 把该 URI 渲染到 `@[label](uri)` 中，ACP 使用标准 `resource_link`；纯文本客户端可以使用同一种行内提及标记。显式 Markdown 提及标记与资源链接会拒绝格式错误的 URI。裸文本只有在负载非空且形状符合 base64url 时才会成为引用，而且解码过程仍须通过规范性校验；空负载或只含标点符号的用法仍按普通讨论文本处理。 + +该服务使用 `ctx.sessionQuery.readSurface(sessionId)`：它优先从实时会话加载一次语料观察结果，使用会话包的规范表层算法执行折叠，并返回与源数据分离的会话头、捕获序号和当前节点。FTS 不是功能依赖：v1 的候选发现只按 id 和 cwd 过滤；未来的标题或正文搜索可以替换候选层，而无需改变引用标识或准备过程。 + +## 快照与投影 + +准备过程按首次出现的顺序去重、拒绝目标会话自身的 id，并且默认最多允许三个引用，所有读取均并行执行。该过程不会返回部分完成的上下文：任何读取、取消、校验或预算错误都会在调用 `send()` 或 `steer()` 前拒绝本次操作。源会话在入队前完成读取，因此源会话后续新增消息、执行压缩、被删除或替换持久化内容，都无法改变目标会话中的快照。 + +投影会保留直接用户消息与 steering（中途引导）、已完成的 assistant 文本，以及携带由 `dsh-compact` 导出的规范来源标记的检查点用户消息。该标记属于压缩功能契约的一部分，而非某个后端包名称。投影会排除压缩前已被遮蔽的节点、工具及其结果、推理（reasoning）、注入的上下文、其他插件用户消息、仅用于日志的记录，以及尚未完成的 assistant 分片。因此，重复压缩只会暴露当前表层仍保留的最新折叠检查点谱系及其尾部消息；系统不提供 raw/current 开关，也不恢复被遮蔽的内容。 + +系统把一个聚合上下文序列化为 JSON，并置于固定的不可信背景警告之后。该警告要求模型不要遵循被引用会话中的指令、权限声明或工具请求，除非当前用户再次提出这些内容。标签安全序列化会把数据中的每个 `<` 无损转义为 JSON `\u003c`；因此源字符串无法拼出外围类似 XML 的标签。逐引用和总字节核算使用同一个序列化器。上下文元数据记录来源与保留事实；模型可见字节通过现有 `context/message` 事件持久化，使目标回放在不新增事件类型的前提下满足「模型可见／日志可重建」不变量。 + +## 消息所有权 + +`send()` 与 `steer()` 会把内容、解析后的来源和上下文一起快照为一条深度冻结、无损 JSON 的收件箱记录。普通消息被认领后，其附带的上下文会作为 `agent/prompt-submit` 的默认附加上下文公开；提示词被阻止时，系统既不写入用户消息，也不写入上下文。waterfall（瀑布式事件）返回的 allow 结果具有最终权威性，因此监听器包装 `next()` 时会保留下游内容与上下文，除非它有意替换这些值。排空 steering 消息时会绕过 `agent/prompt-submit`，先写入 `steering/message`，再写入其上下文。延迟到达的 steering 转换为排队输入时保留同一条记录；取消、dispose（资源释放）和到达终止态后的丢弃则会同时丢弃消息与上下文。`agent/queued` 会报告已冻结的上下文，使观察事件能够描述完整的保留项。 + +这保留了宿主的驱动语义：TUI 在准备完成后根据 agent 状态决定调用 `send()` 还是 `steer()`，因此只有它的排队路径才会分派 UserPromptSubmit 钩子；ACP 则继续调用 `send()`，每个 `session/prompt` 调用一次。引用准备过程不是新的 steering 协议，本身也不会创建轮次。 + +## 宿主适配器 + +TUI 把会话候选与现有 `@` 文件提供方组合在一起。它只准备包含结构化提及标记的提交；等待快照时禁用重复提交；失败时恢复输入；渲染持久化的会话引用上下文时只显示精简的来源列表，不在终端中暴露完整 JSON。 + +ACP 提取 `dsh-session:` 资源链接和规范的行内提及标记，同时保留普通资源链接的渲染方式。若引用有效但可选服务未挂载，系统会返回「功能不可用」RPC 错误；准备失败会发生在占用进行中轮次槽位并调用 agent send 之前。引用准备过程单独拥有中止控制权，因此 `session/cancel` 和桥接释放都能停止待处理的读取。选择器 UI 仍由 ACP 客户端负责。 + +## 预算与保留策略 + +默认配置把单个序列化引用限制在 65,536 个 UTF-8 字节以内，并把包含固定警告在内的完整提示词限制在 196,608 个字节以内。保留策略会优先保留当前压缩检查点和最新的对话单元，再丢弃较旧的非检查点消息。若保留文本过大，系统使用 `dsh-retention` 进行首尾切片并记录准确的省略字节数；若固定元数据与警告所需的字节无法容纳，准备过程会失败，而不会悄然超出契约。 + +## 考虑过的替代方案 + +- **等待 SQLite FTS5**：不予采纳，因为快照正确性依赖按准确 id 读取和规范表层折叠，而不是内容搜索。FTS 只改进候选发现。 +- **把提及标记语法放入 `Agent.send()`**：不予采纳，因为这会迫使核心协议解析 TUI／ACP 的表现层，并阻止带类型的非文本宿主复用同一语义层。 +- **在 TUI 和 ACP 中分别实现引用**：不予采纳，因为投影、安全警告、保留策略和持久化会在不同宿主之间逐渐偏离。 +- **回放原始源日志或恢复被遮蔽的事件**：不予采纳，因为压缩定义了当前模型表层，并且可能有意淘汰敏感或开销高昂的历史内容。 +- **恢复或 fork 源会话**：不予采纳，因为本功能只为一条目标消息提供只读背景，不提供身份或生命周期连续性。 +- **在请求时重新读取源会话并注入**：不予采纳，因为这会让引用变得不确定，取消竞态可能改变其字节内容，目标回放也会依赖可变的外部状态。 + +## 验证 + +单元与集成测试覆盖 URI 无损往返与文本边界标点、显式格式错误的引用、候选排序、投影排除规则、与后端无关的压缩检查点、标签安全封套、去重、自引用、数量限制、读取的全有或全无、取消、字节保留、冻结的消息所有权、提示词阻止、send／steer 顺序、功能缺失、普通 ACP 资源链接，以及 TUI 精简渲染。无密钥 TUI 快照会运行真实的 agent loop（智能体循环）：源表层用一个压缩检查点替换旧的用户／assistant 历史，目标会话提交一个提及标记，捕获到的模型请求包含该检查点和保留的尾部消息，但不包含任一被遮蔽的字符串。 + +## 后果 + +新插件构成稳定的语义边界，不会新增持久化 schema、事件类型、FTS 依赖、源会话订阅或对压缩所遮蔽内容的访问。标准 TUI／ACP 演示组合包会显式挂载它；自定义宿主在挂载该服务并适配输入前保持不变。引用上下文会在配置的界限内增大目标历史，随后可由目标会话的普通压缩进行摘要；完成压缩后，源会话便不再相关。 diff --git a/docs/agent-lifecycle.md b/docs/agent-lifecycle.md index 2134c8b355..b732708e1f 100644 --- a/docs/agent-lifecycle.md +++ b/docs/agent-lifecycle.md @@ -23,7 +23,7 @@ sequenceDiagram Driver-->>SDK: agent/status running Driver->>Session: turn/start Driver->>Hooks: agent/prompt-submit waterfall -

Every backend marks its replacement `user/message` with the package-exported `COMPACT_CHECKPOINT_SOURCE`; consumers call `isCompactCheckpointSource()` instead of coupling checkpoint recognition to one backend. Implementations must forward the supplied signal to summarization. The seam owns no pricing API: the singleton [`ctx.tokenMeter`](token-meter.md) directly owns estimation and replay, while `dsh-compact-basic` owns retention, event sequencing, routed summarization calls, and their configuration. Pressure compaction runs at serial `agent/post-step`, after successful assistant output, tool results, buffered context, and steering are durable but before `step/end`. Once pressure or canonical overflow qualifies, compact-basic invokes optional [`ctx.toolResultPrune`](../../packages/compact/compact-tool-result-prune/README.md) before range selection, remeasures through `ctx.tokenMeter`, and can advance the surface without a summary. Failed-request recovery runs through `agent/request-error` after the failed step closes and authorizes a fresh numbered-step retry only when the surface replacement generation advances, even if later summary work throws after pruning; cancellation still wins. Region boundaries preserve tool-call/result pairing but not whole turns, allowing early closed steps of one oversized turn to compact. `dsh-compact-basic` owns thresholds, retained-tail policy, overflow caps, and failure handling. diff --git a/docs/core-data-structures/core.md b/docs/core-data-structures/core.md index dfdc258cb0..0fe1769135 100644 --- a/docs/core-data-structures/core.md +++ b/docs/core-data-structures/core.md @@ -340,6 +340,22 @@ The fourteen event variants (`turn/start`, `turn/end`, `step/start`, `step/end`, Source: [`packages/core/agent/src/types.ts`](../../packages/core/agent/src/types.ts) +```ts type-equiv +/** + * Message options.

If claimed, it is the sole ordinary message in its turn; its contexts are the prompt waterfall's default additional contexts and therefore append only after admission. The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream `content` and `additionalContexts` unless it intentionally replaces them. A successor waits for the preceding ordinary turn's checkpoint to settle, while cancellation, disposal, a prompt block, or a pre-start failure may drop its contexts with the message. Running `steer()` enters the same record shape in the steering FIFO without dispatching `agent/prompt-submit`: an open turn records the steering message followed by its contexts at the next steering checkpoint before a request or continuation decision, but policy can still stop before another step; steering left after turn close and its checkpoint becomes later queued input with contexts intact unless terminal turn policy, cancellation, or disposal discards it. Open-turn `inject()` uses the same accepted-value boundary but defers in a FIFO while the current step executes assistant tool calls; successful batches place it after all results, and interrupted batches drain it before turn close.

Tag-safe serialization emits every data `<` as the lossless JSON escape `\u003c`; source strings therefore cannot spell the surrounding XML-like tags. The `## My request:` text is a routing cue rather than the trust boundary: referenced data may spell those words inside a JSON string, but it cannot forge the closing `` tag or escape the data region. The same serializer drives each source's independent byte accounting. The context declares `prompt-prefix` placement, so AgentLoop persists one `user/message` or `steering/message` containing the snapshot, `## My request:` delimiter, and effective direct prompt.

The waterfall's returned allow is authoritative, so a listener wrapping `next()` preserves downstream content and contexts unless it intentionally replaces them. After admission, absent or `separate` placement writes an independent `context/message`, while `prompt-prefix` placement bakes context and the effective request into one prompt event.

Late steering retains the same record when converted to queued input, while cancellation, disposal, and terminal discard drop message and contexts together. `agent/queued` reports the frozen contexts so the observation event describes the complete retained item. This preserves host driving semantics: TUI decides `send()` versus `steer()` from the agent state after preparation, so only its queued path dispatches UserPromptSubmit hooks; ACP continues to call `send()` once per `session/prompt`. Reference preparation is not a new steering protocol and does not create a turn by itself. ## Host adapters -TUI combines session candidates with the existing `@` file provider. Candidate lookup follows the editor's cancellation signal, and session id, cwd, and mention labels escape external terminal controls while the canonical URI retains the original id.

Raw `assistant/chunk` events are replay/UI data and are **skipped** in derivation (the assembled message is authoritative). An **empty-content** `assistant/message` is also skipped — a max-tokens step cut off with no content still records an `assistant/message` to host its usage/provenance, but a content-less assistant turn must not enter the provider transcript. - `tool/result` → a user message carrying a `tool-result` block. - `context/message` → a user-role message carrying its `content` verbatim at its chronological position.

Token accounting reads per-step `assistant/chunk { type: 'usage' }` records and treats `assistant/message.usage` as the committed-step fallback when no usage chunk exists; failed model-request attempts have no assistant message, so their usage chunk is the durable accounting record. An operational error's step number is on `turn/end.reason` for `kind: 'error'`, with normalized `LlmFailure` facts for a final model-request failure and message/code for other live errors.

The signal remains authoritative through terminal policy and is retired immediately before `turn/end` publication, so terminal observers and the following durability flush cannot cancel completed turn work. `agent/pre-step` and `agent/post-step` are serial checkpoints around a step's durable work, while `agent/request-error` is the failed-model-request recovery waterfall: it receives the exact error, normalized failure facts, immutable prior-retried facts, and signal after the failed step closes; a retry opens a new numbered step. `agent/turn-stop` is the terminal serial fold: it runs after ordinary continuation and steering folding, and a returned stop remains in force through turn close and flush so later steering cannot create an extra step or turn.

An effective call emits `agent/cancel-requested` with the cause before clearing queued and steering work; observers may synchronize state but cannot veto cancellation. The same-process typed seam adds no runtime validation or compatibility fallback for untyped callers. Repeated active-turn cancellation is first-wins for the signal, and idle cancellation is a safe no-op with no notification. ACP maps to `user`, while in-process parent propagation maps to `parent`. The cause is runtime-only; durable `turn/end` stays coarse `aborted`. - `agent.whenIdle()` — resolve once the agent reaches quiescence after settling out of `running` (idle → immediately; disposed → awaits the loop exit).
