fix(chat): remember model, effort and mode per agent on the host - #9410
The host now remembers the model, effort and mode a user last set in a chat, per agent, and new chats start on them. Every client that creates chats through the host (desktop, mobile, CLI, automations) gets this without its own change.
Recovery, fork, rewind and resume-after-update keep the source chat's model and effort as well as its mode. Before, a recovered desktop chat went back to its launch model, and an ACP chat lost its model on a host update.
Desktop stops keeping its own copy (localStorage chatModeByAgent, chatModelLabel, and the label-based model pass in SessionView). The pane records what the session runs on and sends it back on restart.
Why / Context
ACP's session/set_config_option changes a setting for one session only (verified in OpenCode's ACP server, cli/src/acp/sessions.tsselect). No agent persists it. With no saved choice, a new chat ran on the agent's own default. For opencode acp that is the newest released model (core/src/model.tsModel.default falls back to available[0], sorted newest-first), which today is Crouton Alpha Free. OpenCode's TUI checks the recent models in ~/.local/state/opencode/model.json first, which is why the terminal looked right. Rule adopted: the agent decides what options exist, and Paradev remembers what the user chose.
How It Works
Storage: new chat_selections table in the host's chat.db (harness, category ∈ model | thought_level | mode, value), with one row per agent and category, so it stays small. SelectionMemory reads and writes it. A write is best effort and logs on failure.
Recording:commands.setConfigOption and commands.setMode record a value once the agent accepts it. Adapters' setMode now resolves whether the mode was taken. Plan mode is never recorded as a starting mode, the same rule savedChatMode had. createSession also records its explicit picks when the client sets the new optional rememberSelections flag (used today only by the migration below).
Starting: in createSession, later sources win: saved choices (new chats only) → the replaced chat's journaled selections → explicit modelId/effortId/modeId.
Mode is gated: the saved mode applies only when interactive is set, which only the chat router sets (desktop/mobile chat panes). Automations, CLI and New Workspace launches keep today's behaviour unless they pass a mode, because nobody is watching to answer an approval. Saved model and effort apply to every new chat, which is what fixes the New Workspace case in SUPER-3167.
Applying:AcpAdapter.applyStartSelections sets the model, then the effort once the model change is answered, because effort levels depend on the model. Matching uses the existing startOptionId, so stale ids are ignored and the agent's default is kept.
Shared shape:ChatSelections (modelId/effortId/modeId) and sessionSelections(state) in @superset/chat/core replace the scattered mode-only handling. HarnessStartOptions, HarnessFactoryOptions and UnfinishedSession are built on it.
Desktop migration: on a new chat, a mode still saved in chatModeByAgent is sent as the start mode with rememberSelections: true. The desktop deletes its entry only when the host is at or above CHAT_SELECTIONS_MIN_HOST_VERSION. An older host drops the unknown flag and keeps getting the mode from the desktop, as before.
Manual QA Checklist
Not run in this cloud workspace: it has no OpenCode install and no desktop display. Please check:
OpenCode chat: pick DeepSeek V4.1 Flash, open a new worktree with chat → it starts on DeepSeek, not Crouton Alpha Free
Claude chat: set effort High, open a new chat → model and effort carry over
Switch model mid-chat, quit and relaunch the app → the chat resumes on the switched model, not the launch model
Set "Ask for approval" in a chat, then run an automation on the same agent → the automation does not start in Ask mode
User with an existing saved non-default mode from an older build → first new chat starts in it; chatModeByAgent entry is then gone
Enter plan mode, then open a new chat → it does not start in plan
bun test: chat 108/108, chat-runtime 457/457, desktop 9397/9397
host-service 2722 pass / 23 fail. The same 23 fail on a clean main checkout in this sandbox (workspace naming sessions and a health.check stamp test), so they're unrelated.
Mobile tsc fails here because @superset/host-service/router declarations aren't built. None of the errors touch changed code.
New tests, each confirmed to fail without its fix:
commandsSelections.test.ts: a new chat starts on the remembered picks and an explicit pick wins; a chat nobody opened gets model+effort but not mode; a replacement resumes on the replaced chat's model, effort and mode
acpAdapter.test.ts: start effort is sent only after the start model is answered
widened sessionInfoFromState / sessionInfoPaneData tests: the pane records model and effort, not just mode
Compatibility Matrix
createSession / rewindSession gain an optional effortId. An old host drops it, and the effort is then not applied.
Old desktop → new host: keeps sending its localStorage mode and launch model as explicit choices, which still win. It gains host memory for anything it doesn't send.
New desktop → old host: the desktop keeps its saved mode and sends it on every new chat, as today; it only deletes it once a host reports CHAT_SELECTIONS_MIN_HOST_VERSION or newer. Effort and the new host memory are simply absent. MIN_HOST_SERVICE_VERSION is not raised.
CHAT_SELECTIONS_MIN_HOST_VERSION = "2.0.6" assumes this ships in the next release after 2.0.5. Bump it if the release that carries this PR gets a different version.
interactive is a host-internal command field, not part of the tRPC input, so clients can't set it.
Design Decisions
Host, not renderer storage: one memory for desktop, mobile, CLI and automations, plus journal access for resume paths.
Mode gated on interactive, model/effort not: a remembered "ask" mode would stall a headless run. A remembered model only changes which model runs.
Migration in this PR:packages/trpc/AGENTS.md asks for schema migrations in their own PR, but that rule is for the cloud packages/db. This is the host's local SQLite, shipped with the code that reads it, so splitting it out gains nothing.
Review follow-up
superset-home (fixed in 8437473e): the mode is saved only after the agent accepts it; rewindSession lets explicit values win; SelectionMemory.get is best effort; the legacy mode is kept until the host is new enough to store it (CHAT_SELECTIONS_MIN_HOST_VERSION, via rememberSelections).
cubic / CodeRabbit inline comments (fixed in 3a357456, each with a test that fails without it):
Picks sent with rememberSelections are saved only once the agent reports it took them (AcpAdapter.startSelections()), storing the agent's own id.
A pick that settles after a newer one from the same chat no longer overwrites it.
The start effort is skipped when the agent refuses the start model.
Start selections wait up to 1 s for an agent that lists its options after session/new; the first prompt waits with them. This replaces the grace SessionView's label pass used to give.
Rewinding a stopped chat carries its journaled selections.
The terminal-to-chat fork loader no longer depends on the legacy localStorage mode: an interactive resume outside a journal starts in the remembered mode, and the new fallbackModeId (the harness default) applies only when nothing else names one.
A model picked in the agent switcher is remembered: desktop marks every new chat's explicit picks as the user's.
isSelectionCategory checks own keys only.
Not changed:
Dropped chatModelLabel in saved panes: it was only ever written alongside chatModelId, which the adapter maps onto the agent's options, so saved panes keep their model.
Forward effortId to the native Codex adapter: chat presets use codex-acp; the native adapter never supported effort, so this is a separate, existing gap.
Clear chatEffortId when a model offers no effort: the adapter finds no effort option to apply, so a stale id is ignored.
Agent switch from a restricted chat sends agent-default: intended; it keeps "never more access than the chat being left". Before this PR the target's saved mode could override that.
Known Limitations
New Workspace keeps its own model/effort/mode prefs (useAgent*Preference) and sends them as explicit picks. Moving that picker to the host's memory is SUPER-3049's "remove Default" work.
First-ever OpenCode chat (nothing saved yet) still starts on OpenCode's ACP default. Upstream fix: make opencode acp honour model.json recents.
Rollback
Revert the PR. The chat_selections table stays but is unused; it is harmless.
Users who already moved their saved mode to the host lose it on rollback (localStorage entry deleted), and new chats start in the agent default.
Summary by CodeRabbit
New Features
New chats can reuse the most recently selected model, effort level, and starting mode for the same chat engine where supported. Choices made for a new chat take precedence.
Replacement chats retain the replaced chat’s model, effort level, and mode. Forked and rewound chats retain their model and effort selections.
Improvements
Pending prompts are sent as soon as a session is ready, without waiting for model configuration to finish.
The change adds per-harness storage for model, effort, and mode selections. Runtime commands merge remembered and session-specific selections, and harness adapters apply and report accepted values. Desktop chat flows pass effort selections and synchronize session selection metadata into pane state.

…host
ACP makes a model, effort or mode change last for one session, so a new
chat started on the agent's own default. For OpenCode that is the newest
release (Crouton Alpha Free), not the model the user picked (SUPER-3167).
- chat.db gets a chat_selections table: the last model, effort and mode a
user set in a chat, per harness. setConfigOption and setMode record it.
- A new chat starts on the remembered model and effort. It starts in the
remembered mode only when a person opened it from a chat client; a run
nobody watches cannot answer an approval.
- Recovery, fork, rewind and resume-after-update carry the source chat's
model and effort, not only its mode.
- The ACP adapter applies a start effort after the start model, because
the effort levels on offer depend on the model.
- createSession and rewindSession accept an optional effortId.
- The pane records the model and effort the session runs on, as it does
the mode, and sends all three when the chat restarts. A resumed chat no
longer goes back to the model it was launched with.
- Drop the label-based model pass in SessionView: the adapter already
maps a launch model onto the agent's options and holds the first
prompt until it is set.
- savedChatMode stops writing. A mode saved there moves to the host on
that agent's next new chat, then the entry is deleted.

The selection tests create new chats only before disposing the runtime. A runtime-local map could pass them without persisting selections. Add a test that picks a model, effort, and mode, reopens the same database, and checks a new interactive chat’s selections.

- Line 465: Update the agent-switch flow around explicitSelections(parsed) to
remember an explicitly selected model only after the agent accepts it. Do not
update selection memory for recovery selections, and preserve the existing
startup model-application behavior.
- Around line 732-733: Update the selection merge near explicitSelections and
sessionSelections so explicit model and effort values take precedence over
values carried from sourceLive during rewind. Preserve carried values for
selections that were not explicitly provided.
- Line 733: Update the stopped-session rewind selection resolution around
sessionSelections(sourceLive?.state) to use selections from the replayed session
when the source state has none and no explicit selections were provided.
Preserve explicit selections as highest priority so remembered model and effort
values do not override the replayed source values.

Confirm host selection memory before deleting the saved mode.
An older compatible host can accept setMode without remembering it. The desktop then deletes the saved preference, so later fresh chats can start in a different mode. Retain the preference until the host confirms it supports selection memory.

Clear obsolete effort selections from pane data.
When a complete options update removes thought_level, clear chatEffortId without clearing it during partial startup. Recovery and rewind otherwise forward the old value. If the restarted agent offers that effort again, the adapter can apply it. Preserve the absence through restart rather than restoring a remembered effort.

Apply delayed model selections before sending the first prompt.
If an ACP agent advertises model options after session/new, the host skips the requested model and does not retry it. The first prompt can run on the default model. Retain the selection until options arrive and coordinate prompt dispatch, with a fallback for agents that never advertise options.

If an ACP agent rejects a mode change, this code still saves the requested mode. A later interactive chat can apply it if the agent accepts it then, including a full-access mode after an approval-required selection. Persist the mode only after the adapter confirms it.

When a client creates a codex session with an explicit effortId, the adapter discards it. Codex runs with its configured effort instead of the requested effort. Preserve the selection and apply it to turn/start.

Verdict: minor issues. The host-side design is sound. With the real Claude ACP agent, a new chat now starts on the remembered model, effort and mode (sonnet / high / acceptEdits), where the parent commit fell back to opus / default. Remembered model and effort survive a host restart, and plan mode is not remembered.
Findings (reviewed at 33795776):
AcpChatPane.tsx:245-254: localStorage mode is deleted even when an old host doesn't store it. Gate forgetSavedChatMode on host version.
commands.ts:732-733: in rewindSession the source session's live selections now override the explicit modelId/effortId, unlike createSession. Swap the spread order or drop the fields.
commands.ts:630-631: setMode stores the mode before the agent accepts it. setConfigOption waits for acceptance.
selections.ts:22: get isn't best effort like remember, so a read error fails every createSession.
AcpChatPane.tsx:409-412: an agent switch from a restricted chat now always sends agent-default, which overrides the target agent's remembered mode. Is that intended?
Not verified: the OpenCode case itself (no real opencode in the sandbox) and the desktop chat-pane flows (no local workspace allowed). CI is green; local chat/chat-runtime/desktop tests and tsc pass.
- setMode is saved only once the agent accepts it, as setConfigOption
already was. Adapters' setMode now resolves whether it was taken.
- rewindSession lets an explicit model, effort or mode win over the
source chat's, the same order as createSession.
- SelectionMemory.get is best effort: a read error starts the chat on
the agent's defaults instead of failing createSession.
- A legacy desktop mode now reaches the host as createSession's new
rememberSelections flag, and desktop deletes its copy only when the
host is new enough to keep it (CHAT_SELECTIONS_MIN_HOST_VERSION), so
an older host no longer loses it.

Persist startup selections only after the agent accepts them.
live.create starts the harness asynchronously. This call saves explicit selections before the agent confirms them. If startup fails or the agent refuses a selection, later chats can reuse a value that was never applied. Persist each selection after confirmation, rather than after session creation.

- Settings a client marks as the user's picks are saved only once the
agent reports it took them (new AcpAdapter.startSelections), and the
value saved is the agent's own id.
- A pick that settles after a newer one from the same chat no longer
overwrites it.
- The start effort is skipped when the agent refuses the start model.
- Start selections wait a moment for an agent that lists its options
after session/new, and the first prompt waits with them.
- Rewinding a stopped chat starts on that chat's journaled selections.
- A chat a person resumes outside a journal (the terminal-to-chat fork
loader) starts in the remembered mode; the new fallbackModeId applies
only when nothing else names a mode.
- Every new chat desktop opens marks its explicit picks as the user's,
so a model picked in the agent switcher is remembered.
- isSelectionCategory checks own keys only.

Summary
chatModeByAgent,chatModelLabel, and the label-based model pass inSessionView). The pane records what the session runs on and sends it back on restart.Why / Context
ACP's
session/set_config_optionchanges a setting for one session only (verified in OpenCode's ACP server,cli/src/acp/sessions.tsselect). No agent persists it. With no saved choice, a new chat ran on the agent's own default. Foropencode acpthat is the newest released model (core/src/model.tsModel.defaultfalls back toavailable[0], sorted newest-first), which today is Crouton Alpha Free. OpenCode's TUI checks the recent models in~/.local/state/opencode/model.jsonfirst, which is why the terminal looked right. Rule adopted: the agent decides what options exist, and Paradev remembers what the user chose.How It Works
chat_selectionstable in the host'schat.db(harness,category∈model | thought_level | mode,value), with one row per agent and category, so it stays small.SelectionMemoryreads and writes it. A write is best effort and logs on failure.commands.setConfigOptionandcommands.setModerecord a value once the agent accepts it. Adapters'setModenow resolves whether the mode was taken. Plan mode is never recorded as a starting mode, the same rulesavedChatModehad.createSessionalso records its explicit picks when the client sets the new optionalrememberSelectionsflag (used today only by the migration below).createSession, later sources win: saved choices (new chats only) → the replaced chat's journaled selections → explicitmodelId/effortId/modeId.interactiveis set, which only the chat router sets (desktop/mobile chat panes). Automations, CLI and New Workspace launches keep today's behaviour unless they pass a mode, because nobody is watching to answer an approval. Saved model and effort apply to every new chat, which is what fixes the New Workspace case in SUPER-3167.AcpAdapter.applyStartSelectionssets the model, then the effort once the model change is answered, because effort levels depend on the model. Matching uses the existingstartOptionId, so stale ids are ignored and the agent's default is kept.ChatSelections(modelId/effortId/modeId) andsessionSelections(state)in@superset/chat/corereplace the scattered mode-only handling.HarnessStartOptions,HarnessFactoryOptionsandUnfinishedSessionare built on it.chatModeByAgentis sent as the start mode withrememberSelections: true. The desktop deletes its entry only when the host is at or aboveCHAT_SELECTIONS_MIN_HOST_VERSION. An older host drops the unknown flag and keeps getting the mode from the desktop, as before.Manual QA Checklist
