A-Route RPA Send Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 在 codex/a-route-rpa-send 分支实现 A 方案：通过受控 UI Automation 路线让 isphere_send_message 能配置为真实 UI 写入并点击发送。

Architecture: Go MCP 继续保留稳定 isphere_send_message 接口、hash、idempotency、audit。新增 A-route connector 调用 C# ISphereWinHelper 的 UIA action op；C# helper 根据窗口句柄、发送框 AutomationId、发送按钮 AutomationId 写入文本并点击。B-route sidecar 仍是主路线，但当前不可测时先实现 A-route 功能兜底。

Tech Stack: Go 1.23.4, github.com/modelcontextprotocol/go-sdk, Windows PowerShell, .NET Framework C# helper, Windows UI Automation.

Global Constraints

• Repository root: E:\coding\codex\isphere-ai-bridge.
• Active branch: codex/a-route-rpa-send.
• Do not use rg; use git ls-files, ag, grep -R, or PowerShell commands.
• Local machine cannot log in; use synthetic WinForms/UIA verification for local tests.
• User explicitly removed human approval as a product gate for A-route; do not add approval IDs or approval queues in this plan.
• Keep audit redaction: do not store raw message body or raw idempotency key in committed docs/audit tests.
• Real UI action requires explicit env configuration; default MCP behavior remains preview/blocked.

---

Task 1: Go connector must carry raw content to action connector

Files:

• Modify: internal/tools/send_message_connector.go
• Modify: internal/tools/isphere_send_message.go
• Modify: internal/tools/isphere_send_message_test.go

Interfaces:

• Produces: SendMessageConnectorRequest.ContentText string for connector execution only.

• Audit and response still omit raw content.

• Write failing test proving injected connector receives raw ContentText while response/audit do not leak it.

• Run focused test and confirm failure.

• Add ContentText to normalized args and connector request.

• Run focused send-message tests.

Task 2: Go A-route UIA connector adapter

Files:

• Create: internal/tools/send_message_uia_adapter.go
• Create: internal/tools/send_message_uia_adapter_test.go

Interfaces:

• Produces: type UiaSendMessageAdapterConfig struct { HelperPath string; TimeoutSeconds int; Hwnd string; SendEditorAutomationID string; SendButtonAutomationID string; Mode string }.

• Produces: NewUiaSendMessageConnector(config UiaSendMessageAdapterConfig, caller UiaHelperCaller) SendMessageConnector.

• Helper op: uia_send_message.

• Write failing tests for missing config and successful helper call using a fake helper caller.

• Implement adapter request mapping.

• Run focused adapter tests.

Task 3: C# WinHelper UIA send action

Files:

• Create: native/ISphereWinHelper/UiaSendAction.cs
• Modify: native/ISphereWinHelper/Program.cs
• Modify: scripts/verify-win-helper.ps1

Interfaces:

• Helper op uia_send_message args: hwnd, send_editor_automation_id, send_button_automation_id, content_text, content_sha256, target_ref.

• Helper data: action_mode="uia_send_message", typed_text=true, clicked_ui=true, sent_message=true, content_sha256, target_ref, editor_found, button_found.

• Add synthetic WinForms verification that starts a form with rtbSendMessage, btnSend, invokes uia_send_message, and verifies button-click side effect in a label.

• Implement UiaSendAction with ValuePattern/Win32 fallback and InvokePattern/click fallback.

• Run scripts\verify-win-helper.ps1.

Task 4: Wire A-route connector into MCP env config

Files:

• Modify: internal/tools/isphere_send_message.go
• Modify: internal/mcpserver/server.go
• Modify: scripts/verify-go-mcp.ps1
• Modify: docs/go-mcp-runbook.md
• Modify: docs/current-status-card.md

Interfaces:

• Env ISPHERE_SEND_CONNECTOR_MODE=uia_rpa enables A-route connector.

• Env ISPHERE_SEND_UIA_HWND, ISPHERE_SEND_UIA_EDITOR_AUTOMATION_ID, ISPHERE_SEND_UIA_BUTTON_AUTOMATION_ID, optional ISPHERE_SEND_UIA_HELPER_PATH configure the action.

• Default env remains no real send.

• Add config loader and tests around production connector availability.

• Keep standard smoke deterministic with env cleared.

• Add server env routing test; helper synthetic UIA smoke covers the local write/click action.

• Update docs with minimal usage.

Task 5: Verification, commit, push

• Run git diff --check.
• Run go test ./....
• Run go build ./cmd/isphere-mcp then remove root binary.
• Run powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-win-helper.ps1.
• Run powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-go-mcp.ps1.
• Commit and push branch codex/a-route-rpa-send.
