What

Stranger walk 10-31: a webhook agent was created, the MCP snippet copied three times, the Terminal listener never copied, so the agent never answered.

• Listener available: the Claude Code MCP block is folded in a <details> under the listener, summary "Claude Code in your own sessions. This does not answer @mentions."
• No listener (Windows, or Linux in a pod that is not invite-only): the first line says <name> will not answer @mentions from here., with the existing "Run it here" action as a button when hosting is on. The MCP block stays open there, since it is the only way in.
• en and zh-CN strings.

Tests

Render tests for both cases (folded and labelled; wont-answer line first, MCP open, Run it here only when hosting is configured). V2AgentBYOListenSnippet 40/40 locally.

Walkthrough

The BYO screen now shows guidance when a listener is unavailable and offers hosted startup when configured. It keeps Claude Code MCP instructions visible without a listener and folds them into a disclosure when a listener is available. English and Simplified Chinese messages and tests cover these states.

Changes: BYO listener guidance

Summary

Listener states and MCP instructions frontend/src/v2/components/V2AgentBYO.tsx, frontend/src/i18n/locales/en.json, frontend/src/i18n/locales/zh-CN.json, frontend/src/v2/__tests__/V2AgentBYOListenSnippet.test.tsx

When the listener is unavailable, the screen shows a warning and, if hosting is configured, a “Run it here” action with inline startup errors. The MCP instructions remain visible in this state. When the listener is available, the instructions appear in a disclosure with a summary clarifying that they do not answer @mentions. The post-issue hosted offer is limited to cases where the listener is available. Translations and tests cover these states.

Merge Risk: Low · up to 8d49d

The screen currently shows the intended action, but the test does not protect against a duplicate button appearing after 30 seconds.

Self-review (Sonnet subagent, read-only) at 3bb63bc. Real finding: the new Run it here button's failure was only rendered inside the hosted-offer section, so after a copy a failed click showed nothing; and two hosted buttons could show together. Fixed in this head: the error renders beside the new button, and the offer section is skipped when there is no listener (the new button replaces it). Test covers the single button and the failed start. Nits not taken: IIFE kept (no hooks inside), summary wording. zh-CN checked. V2AgentBYO suites 176/176 locally.

Follow-up Comments

Test the single-button state after the delayed offer fires.

455-456: Trivial · Maintainability & Code Quality · Quick win

Test the single-button state after the delayed offer fires.

This assertion runs before the 30-second offer timer. If the listenerAvailable guard at V2AgentBYO.tsx Line 1946 is reverted, this test still passes. Advance that timer in the hosted/no-listener test, then assert that only the inline “Run it here” button appears. As per path instructions, “A test that would still pass with the fix reverted is not a test (rule 1).”

Update the hosted/no-listener test in V2AgentBYOListenSnippet.test.tsx to
advance the delayed offer timer before checking the button count, so the
assertion verifies that only the inline “Run it here” button appears after the
offer fires.

Browser check at 8d49db7 (headless Playwright, dev:live copy on :3202, API mocked: invite-only private pod, hosting configured; shots kept locally). Mocked render covers layout only; the live data goes in the post-deploy walk.

Both cases, at 1440 and 390, light and dark (8 renders), no horizontal scroll in any:

• With a listener (Mac): the MCP block is one folded <details>, summary "Claude Code in your own sessions. This does not answer @mentions."; opened, the snippet and Copy button fit at 390 in both themes.
• No listener (Windows): first line "seat-agent will not answer @mentions from here." with a "Run it here" button directly under it, then the existing reason; no <details>, the MCP block stays open as the way in. One Run it here button on the page.
