agent pane: localized strings for the failed-turn causes (split from #24312) by teamleaderleo · Pull Request #24529 · manaflow-ai/cmux

teamleaderleo · 2026-10-23T10:56:32Z

Leo-ask: ask-427cc7d8f5

Leo: "we need to have prettier errors" and "we also wanna make sure we have good recoverable/informative disk errors tailscale erros for acpmux".

What changes

This adds the localized strings for #24312's failed-turn card to the agent pane's catalog (webviews/src/agent-session/acpmux/Localizable.xcstrings). There are five keys in 21 languages, with non-English entries marked needs_review:

turn.failure.diskFull
turn.failure.tailscale
turn.failure.agentExited
turn.failure.spawnFailed
turn.failure.generic

No code reads these keys until #24312 lands, so this changes nothing on screen. The strings are split out so #24312 stays under the ~800-line rule. They are #24312's catalog lines unchanged, so once this lands, #24312's base merge drops them from its diff with no conflict.

Checks

On huge-blue at this head:

bun run check:catalog-keys (no repeated key): clean.
bun run strings: generates.
test/pane-english.test.ts: 3 pass.

Changelog

none

No capture: catalog only, nothing on screen changes.

Summary by cubic

Adds the localized strings for the agent pane's failed-turn error card to Localizable.xcstrings, with no visible behavior change. The five turn.failure.* keys ship in 21 languages, with the Japanese disk-full line reworded per review so it reads naturally.

No code reads these keys yet — PR #24312 consumes them. Landing them first keeps that PR under its size limit, and since they're copied unchanged, #24312's merge drops them from its diff with no conflict.

^{Written for commit 2ff0a5c. Summary will update on new commits.}

…out (#24312) * agent pane: a failed turn's error card that names the cause and the way out Leo: "we need to have prettier errors" and "we also wanna make sure we have good recoverable/informative disk errors tailscale erros for acpmux". A failed turn showed acpmux's bare "agent process closed" with an outlined Copy error. It now draws a card: one human cause line, the way out first (Retry, or Switch model for capacity and keys), and Details opening the agent's own words with Copy error. New kinds: a full disk, a tailnet that no longer reaches the chat's machine, an agent that quit mid-turn and one that could not start; anything unnamed reads "<agent> ran into a problem and stopped." acpmux's typed reason (the turn's errorCode, a string) wins over the words when it names one. The surface is the turn-error-card experiment (glass card, accent rail, quiet note); the glass card ships.

Quit and could-not-start now come last, after every named cause. - A tailnet host in a message that answered (a 401, a 529) read as Tailscale. Tailscale now needs a sign it did not connect. - A capacity failure drew no Retry in the card, though the test and the docs promise one after Switch model: Retry follows it, unfilled.
