A two-way session bridge between VS Code Copilot Chat and external automation. 外部自动化与 VS Code Copilot Chat 之间的双向会话桥。
SessionBridge is an independent open-source product that provides a two-way session bridge between external scripts / unattended tasks (e.g. ProofRail, whois A/B flows) and VS Code Copilot Chat — it delivers messages and can also capture responses, supporting human review and confirmation at critical checkpoints.
It originates from the IPC Chat Sender practice in the whois project, but is
positioned as a standalone product:
- Session-level bidirectional (Session, not Send):
conversationId/turnIdidentify conversation turns and reuse VS Code's chat panel, history, and human–AI interaction mechanism. - Modes:
visible: message visible in the chat panel, supports human–AI exchange (primary mode; ProofRail development relies on it for review/approval).silent: LM API direct, zero UI, captures AI response (status tickets / unattended automation).auto: trysilentfirst, fall back tovisible.
- Cross-platform:
extension/(VS Code extension) +client/(Python 3 client as the primary implementation, PowerShell compat layer, and a POSIXshclient for Linux/macOS — same channel contract) +installer/(install/update/uninstall).
- Adopted SessionBridge /
sessbridge/ 会话桥: GitHub user/org 404, repo search 0, npm 404; semantically matches "session-level bidirectional". - Abbreviation rule: never use
sb(unpleasant association in Chinese internet context); prefersessorsbrinternally.

# 1. Install the extension (then reload the window)
powershell -File installer\install.ps1 -Force
# 2. Deliver a message (default visible: appears in the chat panel)
python client\sessbridge.py send --message "hello"
# 3. Silent mode: LM API direct, captures the AI response
python client\sessbridge.py send --message "status" --mode silent --model "DeepSeek V4 Flash"
# 4. PowerShell compat layer
.\client\ps\sessbridge.ps1 -Message "hello"
# 5. POSIX sh client (Linux/macOS)
sh client/sh/sessbridge.sh send --message "hello"
# 6. Contract tests

sessbridge-0.1.0.vsix and sessbridge-0.1.0-py3-none-any.whl (verify with
SHA256SUMS):
# --- VS Code extension (.vsix) ---
# Install (from a downloaded .vsix, or local dist/)
code --install-extension sessbridge-0.1.0.vsix
# Uninstall
code --uninstall-extension larsonzh.sessbridge
# --- Python client (wheel) ---
python -m pip install sessbridge-0.1.0-py3-none-any.whl
# Verify (console script on PATH, or python -m)
sessbridge --help
python -m sessbridge --help
# Uninstall
python -m pip uninstall sessbridgeThe wheel target is the
sessbridgemodule (stdlib only, no dependencies); the console script is only on PATH when the PythonScriptsdirectory is.
Authoritative spec: docs/RFC-sessbridge-channel-protocol-v1_EN.md
Boundary note: ProofRail (证轨) relies on the visible mode for human review
and confirmation at critical development checkpoints (see Modes above); its
unattended automation consumes the silent channel and file queue. visible
human interaction is a SessionBridge product capability.

SessionBridge 是一个独立开源产品:让外部脚本、无人值守任务(如 ProofRail / whois A/B 流程) 与 VS Code Copilot Chat 双向交互——既能投递消息,也能接收并捕获人工回复,支撑任务关键节点的 人工审核与确认。
它源自 whois 项目的 IPC Chat Sender 实践,但定位为独立产品:
- 会话级双向(Session 而非 Send):以
conversationId/turnId标识对话回合,利用 VS Code 现有聊天面板、聊天记录与人机交互机制,支持人与 AI 交流。 - 模式:
visible:消息在聊天面板可见,支持人与 AI 交流(主要工作方式;ProofRail 开发期关键 节点的人工审核/确认依赖此模式)。silent:LM API 直达、零 UI 干扰、捕获 AI 响应(无人值守状态票等自动化场景)。auto:先 silent,失败回退 visible。
- 跨平台:
extension/(VS Code 扩展)+client/(Python 3 跨平台客户端为主,PowerShell 兼容层与 POSIXsh客户端(Linux/macOS)共享同一通道契约)+installer/(安装/更新/卸载)。
- 采用 SessionBridge /
sessbridge/ 会话桥:GitHub 用户/组织 404、仓库检索 0、 npm 404,全部未占用;语义贴合“会话级双向交互”。 - 简称纪律:不用
sb(中文互联网语境存在不雅联想);内部建议sess或sbr。
