Promote and complete the global agmsg agent-messaging environment

[orangewk]

Goal

Make the Windows user-global agmsg environment usable and discoverable across Claude Desktop, Codex, Qwen Code, and future CLI agents.

Current evidence

• Shared agmsg scripts and PowerShell wrapper are installed under C:\Users\orang\.agents\skills\agmsg.
• Claude ↔ Codex E2E succeeded on 2026-08-01 and 2026-08-04.
• agmsg-e2e34 currently has claude-desktop, codex-tui, and qwen-tui.
• Claude → Qwen currently has a PING but no ACK.
• Claude monitor is configured but not running; Qwen and the current Codex project are off.
• Claude global guidance still says agmsg is not a viable delegation path, which conflicts with the successful Claude ↔ Codex E2E.
• Qwen user settings contain both Standard and Token Plan DashScope endpoints, while the active model is Standard-side.

Ordered work

• Correct the stale Claude global guidance while retaining the boundary between agmsg messaging and direct model delegation.
• Add Qwen to the Claude /agmsg usage and spawn guidance, including bounded boot prompts and the no-idle-wakeup limitation.
• Re-register Claude monitor delivery and document the required session restart.
• Align Qwen authentication/model selection with the user's Token Plan endpoint without exposing credentials.
• Enable Qwen turn delivery where appropriate and complete a live Claude Desktop → Qwen TUI → Claude Desktop E2E.
• Update the PC-local usage map so each installed agent has a discoverable entry point.

Acceptance criteria

1. A fresh Claude session can discover /agmsg, join the intended team, and spawn or address Qwen with an explicit stop condition.
2. Claude monitor receives messages after the documented restart.
3. Qwen uses the intended Token Plan model/endpoint and can execute one model turn.
4. A live message sent from claude-desktop is acknowledged by qwen-tui and the ACK is observable in Claude's inbox/history.
5. Local instructions no longer contain contradictory claims that suppress the supported workflow.

Progress update: (1) corrected the stale Claude global guidance in C:\Users\orang\.claude\CLAUDE.md; agmsg is now documented as the active messaging path, distinct from direct model delegation. (2) extended C:\Users\orang\.claude\commands\agmsg.md with Qwen spawn/boot-prompt guidance and the idle-TUI limitation. (3) re-registered Claude monitor for C:/dev/agmsg-watcher-visibility; hook is present, but the Claude Desktop session must restart for its watcher to attach. (4) aligned C:\Users\orang\.qwen\settings.json to the existing Token Plan definition: qwen3.7-plus + token-plan endpoint + BAILIAN_TOKEN_PLAN_API_KEY reference; credentials were not changed. (5) set project Qwen delivery to turn; PowerShell Stop hook is present. (6) found and fixed the Qwen spawn root cause: a leading /agmsg actas prompt was consumed as a Qwen slash_command with sentToModel=false, so no model turn occurred. Fix is in PR #42 commit 099b463, Qwen tests 6/6. Live ACK is still pending because the current Qwen 0.21.8 TUI process remains in model/update processing without a transcript or ACK. Note: a diagnostic output accidentally included existing credential values; do not reuse those values and rotate the Token Plan key as a precaution.
