cmux NEXT: suggested tasks on by default by teamleaderleo · Pull Request #22089 · manaflow-ai/cmux

teamleaderleo · 2026-10-19T19:29:46Z

Suggested-task chips are now on by default. An agent can suggest follow-up work (offer_session / suggest_tasks), and the chat shows it as a card with Start, Start all and Do it here. Started tasks become child chats beside this one, and their results come back here. Until now all of this sat behind the agent.suggestedTasks Debug toggle, which defaulted off, so nobody saw it.

The Debug toggle stays (DEV and NIGHTLY only). Turning it off removes the chips, and the daemon starts without ACPMUX_OFFER_TOOLS. Release and RC always use the default, so there the chips are always on and every local session gets the cmux-sessions MCP server. Leo's call on 2026-10-19: the chips shouldn't be off by default.

Verification

AcpmuxOfferToolsTests: byDefaultTheDaemonGetsTheOfferTools (new default) and turnedOffTheDaemonGetsNoOfferTools. The test commit (cmux NEXT: test that suggested tasks are on by default) is red: on base, an unset toggle launches the daemon without the offer tools. The flip makes it green. Not yet observed: cmux-next swift test is skipped on this PR (no full-ci), so the red-then-green is from reading the test, not a run; no local Swift build.
The chip UI itself is unchanged and covered by webviews/test/agent-pane-suggested-tasks.test.ts.
Risk: normal (risk_tier.py classify: Swift tunable, defaults snapshot, webview comments; the test and ci-target-graph.json are low). No migration: an unset toggle now reads on, and a stored true keeps its value. A stored opt-out was never written under the old default (the store drops values equal to the default), so earlier opt-outs come back on.
The ci-target-graph.json and schemas/defaults changes are PR-autofix regeneration, not part of this change.

Changelog

Changed: cmux NEXT shows agents' suggested tasks by default.

Summary by cubic

Suggested-task chips now show by default. The agent.suggestedTasks Debug toggle previously defaulted off, so agents' follow-up suggestions never appeared; it now defaults on. Turning it off still removes the chips and starts the daemon without ACPMUX_OFFER_TOOLS.

The daemon-offer test now covers both the default-on and turned-off cases.
Updates the CI target graph, removes stale default keys for browser focus-search and iPhone connections, and syncs the toggle's default across webview comments.

^{Written for commit 834fa8f. Summary will update on new commits.}

Review follow-up on #22089: three comments still said off by default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Review (subagent, correctness first): SHIP at 48b0a3e

The subagent reviewed ee15854; 48b0a3e only fixes three comments that still said off by default. The flip reaches both paths: the daemon through AgentPaneHost → offersSessionTools, and the page through .suggestedTasks at load, handshake and every change. The Chief host starts no daemon. Nothing needs migrating: the store drops values equal to the default, so earlier opt-outs come back on, which is intended. Non-blocking points, now in the body: Release and RC have no off switch, and AcpmuxOfferToolsTests hasn't run on this PR (swift test is skipped without full-ci).

…ff (#23284) * fix(cmux-next): let sessions.promptSuggestions turn suggested tasks off #21897 added the setting but ORed it with the agent.suggestedTasks Debug toggle, which #22089 had made default on, so turning the setting off did nothing. The setting now decides and defaults on (today's behavior); the Debug toggle defaults off and only forces suggestions on. The host's default closure reads forNextDaemon alone, which already carries both. The old test compared isOn to the Debug toggle's value, which hid the bug; the new one turns the setting off and expects suggestions off.
