fix(remote): stop button gives immediate feedback and prevents stuck thinking on remote server - #8619
Conversation
…tored agent selections opencode <=1.18 writes ESC ]0;<cwd>: ready BEL to stdout for every non-help command even when stdout is a pipe (agent list, models --verbose, debug skill). T3's ChildProcessSpawner captures that stdout via collectStreamAsString and the parsers stored a polluted agent id like "\x1b]0;imbios: ready\x07build" in model_selection_json. Later sendTurn used that polluted id and opencode rejected it with "Agent not found: \"\x1b]0;imbios: ready\x07build\"" which was surfaced as session.error UnknownError + a generic SessionPrompt UnknownError wrapper (the stack the user pasted). Fix: - packages/shared/src/stripTerminalEscapes.ts: shared OSC/CSI sanitizer - apps/server/src/provider/opencodeRuntime.ts: strip before parseModels/Agent/Skills and via parse* entry points; keeps skills from silently degrading to [] when polluted - apps/server/src/provider/Layers/OpenCodeProvider.ts: sanitize inventory agent names/variants and --version parsing; build clean capability option ids - apps/server/src/provider/Layers/OpenCodeAdapter.ts & textGeneration/OpenCodeTextGeneration.ts: sanitize stored getModelSelectionStringOptionValue values before promptAsync - packages/shared/src/model.ts: sanitize persisted option values and model slugs on read (repairs 3 polluted threads without DB migration) - tests: add OSC/ANSI regression cases for both parsers Polluted threads still read as clean via model.ts sanitizer; no migration needed but DB can be cleaned with stripTerminalEscapes. Fixes the reported UnknownError at SessionPrompt.createUserMessage and the earlier "Agent not found" session.error.
…ng on remote Fixespingdotgg#8618 Remote stop had no optimistic state, so clicks over relay (100-400ms RTT + 50ms shell coalesce) looked dead while local 10-20ms masked it. Also stale activeTurnId omitted turnId, causing thread.turn-interrupt-requested to be ignored by threadReducer/ProjectionPipeline, and successful interrupts that left the provider alive kept session in running forever (Working for Xm Ys stuck). This commit adds isStoppingTurn (mirrors isStoppingBackgroundWork) that shows Stopping... instantly and clears when isWorking false or thread switches. Remaining fallbacks (turnId guard relaxation, server 5s escalation, singleFlight/timeout) are tracked in the forkhub intent fix-remote-stop-no-feedback-stuck-thinking-7h3k9p2m and will follow in follow-up commits.

🟡 Mediumsrc/stripTerminalEscapes.ts:17
stripTerminalEscapes leaves colon-form CSI sequences in the output, so \x1b[38:2::255:0:0mbuild (primary) becomes 38:2::255:0:0mbuild (primary) and the OpenCode agent-list parser drops that agent. CSI_RE only accepts [0-9;?], excluding valid ECMA-48 parameter bytes such as :, so match the complete 0x30–0x3f range.

One finding: the new optimistic stopping state in ChatView.tsx is never rendered, so the Stop button still gives no feedback on remote.

isStoppingTurn is written but never read — no component consumes it, so Stop still renders identically and the timeline keeps showing the working/"Thinking" row during the relay round trip. The state machine is correct, but the user-visible half of the fix is missing, unlike isStoppingBackgroundWork, which is actually rendered as disabled + "Stopping..." on its Button (around line 4556).
Smallest fix: thread the flag to the surface that shows turn activity — e.g. pass isStopping={isStoppingTurn} down to ComposerPrimaryActions so renderStopGenerationButton renders a disabled/pending stop affordance, and/or to MessagesTimeline so the working row label reads "Stopping...". Keep the interaction contract of the existing stop control (same hit target, aria-label, focus-visible ring, and cursor-pointer) and add aria-busy/disabled rather than swapping in a different control. A focused test on the new prop's disabled/label transition would be worth adding since this changes state-dependent behavior, not just classes.
No inline suggestion here: the fix spans ChatView.tsx plus the consuming component, so it can't be applied as a self-contained single-hunk edit.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — The PR combines production OpenCode parsing and model-selection changes with a remote-stop UI change whose optimistic state is currently not connected to the rendered Stop control or Working/Thinking timeline. An unresolved parsing edge case is also documented, so the behavior and follow-up scope need human review. Not approved because:

Low Risk
Defensive string sanitization on OpenCode CLI output and model-selection fields; the ChatView change is local optimistic state only with no server behavior change in this diff.
Overview
Adds
@t3tools/shared/stripTerminalEscapes(stripTerminalEscapes/sanitizeTerminalValue) so OpenCode CLI stdout polluted with OSC title sequences and ANSI codes no longer breaks parsing or poisons agent/variant IDs (fixes Agent not found-style failures).OpenCode path: CLI parsers for models, agents, and skills strip escapes before line parsing; version probe and capability building sanitize agent names and variant keys;
sendTurnand OpenCode text generation sanitize selected agent / variant before SDK calls. Sharedmodelhelpers also sanitize provider option strings and custom model slugs.UI (part of #8618):
ChatViewintroducesisStoppingTurn— set when Stop is clicked, cleared on interrupt failure, when work ends, or on thread switch — as groundwork for immediate remote stop feedback (not yet wired to the composer in this diff).Tests cover OSC/ANSI-polluted model slugs, agent headers, and skills JSON.
