Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds ACP-backed OpenCode 2.0 sessions and authenticated text-generation paths. Configuration can race with session reload and target a closed session, while configured remote passwords may be sent through Basic authentication without transport validation; the new provider process boundary also needs explicit containment ownership.

Effect service conventions review of the new OpenCode 2.0 ACP code. Three small violations found; everything else (namespace subpath imports, dependency acquisition via yield* Tag, inline service interface additions on AcpSessionRuntime) looks consistent with the conventions.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces significant new capability: OpenCode 2.0 preview support with automatic binary detection, background service adoption, session reload functionality, and UI changes for free-form questions. The scope of new integration and runtime behavior changes warrants human review. You can add or adjust custom eligibility rules. Learn more. |

stdout before constructing failure details or local provider health-check
messages. Update the startup readiness flow around setReadyFromStdoutChunk and
the OpenCodeRuntimeError detail construction to remove or replace any “server

failure-path test verifying the password never appears.

- Around line 384-390: Update the createOpenCodeSdkClient configuration in the
server connection generator so configured remote credentials are included only
when the target URL uses HTTPS; never attach openCodeSettings.serverPassword to
non-loopback HTTP URLs. Preserve generated loopback credentials separately, and

One finding: the composer attachment dedupe key lost its field separators, which can silently drop a restored stash image. The free-form pending-input copy changes (widened activeQuestion prop, pendingCustomAnswerLabel, panel option gating) look consistent with the panel's new no-options path.
Posted via Macroscope — UI Consistency
A merge cleanup stripped literal NUL bytes from the stash-restore dedupe key and snapshot key, letting distinct field combinations collide and silently drop restored stash images. Use explicit \u0000 escapes matching composerImageDedupKey.
The opencode2 preview went through ACP over stdio, spawning one child process per provider instance and losing the shared background service that v2 clients use. The HTTP adapter already speaks the v2 SDK and its event stream, so the ACP layer was a worse copy of what we had. - auto-upgrade the default "opencode" binaryPath to "opencode2" when it resolves (enabled instances only), no settings change needed - adopt an already-running OpenCode 2 background service from its registration file (~/.local/state/opencode/service.json) after a health check; explicit serverUrl/serverPassword still wins and adopted services are never killed - drop the opencode2 ACP adapter and route every opencode binary through the native HTTP adapter Model: ox-alpha (OpenCode)

Closing this in favor of a fresh, smaller OpenCode 2 integration that follows OpenCode's single-server attach model and keeps ACP changes out of scope. |

The OpenCode 2.0 preview ships as
opencode2and replaces the stable HTTP session flow with ACP. T3 Code previously treated that binary as stable OpenCode, so provider checks, inventory, sessions, cancellation, and text generation did not work correctly.This detects
opencode2, loads its CLI inventory with readable labels, runs chat sessions over ACP, maps model, effort, and mode selection, preserves approvals and elicitation, and recovers from the preview active-prompt race. Explicit server URLs stay on the HTTP adapter. Local text generation now captures the generated preview server password.Tested with 106 focused server tests, targeted lint and formatting, server typecheck, and the installed
opencode2 v0.0.0-beta-17639for inventory, ACP create/close/load, and authenticated HTTP endpoints.Built with GPT-5.6 in T3 Code via Codex.
Note
High Risk
Touches provider process spawning, HTTP Basic auth/passwords, ACP session lifecycle (reload/cancel), and MCP registration for shared servers. Failures here can break OpenCode sessions or leak credentials in diagnostics.
Overview
Adds first-class OpenCode 2.0 preview (
opencode2) support: auto-upgrade the defaultopencodebinary whenopencode2 --versionworks, parse v2 CLI inventory, skip the stable min-version gate, and expose an Effort model option. Local v2 servers authenticate with a generated Basic password (redacted in logs); an already-running Unix background service is adopted fromservice.jsonafter a health check. Explicit Binary path / server URL still win. MCP tools are not registered on external/adopted servers.ACP session runtime can now
reload(close + load, fail orphaned tool calls) andcancelAndWait. Config/mode/model writes serialize behind the prompt semaphore. Failed reload leaves the runtime Closed instead of restarting the child. Mock agent coverage expands for elicitation, pending tools, and ordered cancel/reload.Web and mobile composers keep free-form questions with empty
optionsinstead of dropping them, and copy/placeholders no longer mention option selection.Reviewed by Cursor Bugbot for commit 591181a. Bugbot is set up for automated code reviews on this repo. Configure here.
