Claude and Codex can both predict your next message after a turn. Claude Code shows it as a prompt suggestion, and the Codex app has its Tab suggestion. T3 Code never showed either one.
Now there is a Labs option, Suggest next prompt, off by default. When it is on and a Claude or Codex turn completes, the empty composer shows the predicted next message. Press Tab to fill it in, then edit or send it, or press Escape to dismiss it.
The hint is a key, so it never reads as part of the suggested prompt:
| Labs option | Claude suggestion | Codex suggestion |
|---|---|---|
| Labs option | Claude suggestion | Codex suggestion |
Why Labs, off by default: each suggestion is one extra model request, so it uses some plan usage. The request reuses the turn's prompt cache, but cached input still counts.
How it works
promptSuggestionsEnabled is a server setting shown in Settings > Labs. Adapters read it live: Codex before each sample, so a change applies at once; Claude when it opens a query, so open Claude threads follow a change after they restart.isDelegatedAppThread).promptSuggestions option and forward the prompt_suggestion message it sends after result. Claude decides when to suggest. It skips the first turn, turns near the usage limit, and sometimes others. We also skip runs that only replay background work, because a late suggestion there belongs to the user turn before it.thread/sample request. It runs one low-effort response on a hidden fork that shares the parent's prompt cache, and fails quietly on Codex versions without that request.prompt_suggestion.updated adapter event in its event pump, the same way it handles command_output.delta, and keeps the latest suggestion per thread in memory. Clients read it from a new orchestration.subscribePromptSuggestion stream, which checks the thread before each suggestion and never serves one for a deleted thread. The client subscribes only when the setting is on, the device has a mouse or trackpad, and the thread has a run./clear arms a fresh session, and during dictation. Tab fills it through the same path as other inserts, so the typing guard sees it. Escape dismisses it for that run in every open composer.thread/sample needs Codex 0.165 or later. main already pins managed Codex to 0.166.0.Not included, as follow-ups: mobile (no Tab key, needs a tap control), an eval for the Codex sample prompt, and a unit test for the composer key handler's Tab and Escape branches (checked by hand in a real client). Codex runs UserPromptSubmit hooks on the sample turn; that is upstream behavior.
Proof: vp run check:changed passes. Adapter tests cover root, MCP-launched, subagent, and remote threads, and turning the flag off after a Codex session opens. A session-manager test covers deleted threads. Each fails without its guard. In a dev server with the Labs option on, Claude Haiku 5.5 and Codex GPT-5.6 Luna threads showed suggestions, Tab filled them, and Escape dismissed them with Tab then moving focus out of the composer.

be831The opt-in Labs feature shows predicted next prompts after Claude and Codex turns. A few minor concerns remain: very long suggestions are not clamped, Codex sampling relies on the provider's own timeout, and suggestions are sampled while background work runs. None of these blocks the workflow.

Explanation
The title "feat: Labs option to suggest your next prompt after Claude and Codex turns" matches the main change. The changeset adds an opt-in Labs setting (promptSuggestionsEnabled) that shows a predicted next prompt in the composer after Claude or Codex turns. Adapters, the session manager, the new RPC stream, and the composer UI all support that feature. The title is specific and uses a conventional commit prefix. It is 74 characters, which is slightly long but readable.
Explanation
The description covers the problem (Claude and Codex next-prompt suggestions were never shown in T3 Code), the change (a Labs setting, adapter and session-manager transport, and composer behavior), and verification (checks run, adapter and session-manager tests, manual dev-server testing, and an independent verifier's report). It also documents scope limits and follow-ups. Two template items are weak. The Scope and approval section gives no linked triaged issue or maintainer approval. It also does not say why the change qualifies as focused configuration of an established capability. The Problem section does not state expected behavior or reproduction steps in the template's form. The description also omits the template's required model/harness line in a clear form, though it names Claude Code and Sol-loop tooling. The verification section is detailed. The PR is a substantial feature, not a small fix, so the missing approval link is a material gap under the template.
Resolution
Add a Scope and approval entry. Link the triaged issue or discussion where a maintainer approved this direction and scope, and include the approval comment. If no prior approval exists, explain why this qualifies as focused configuration of an established capability. Explain what already exists (for example, the existing composer and adapter paths), what the Labs option controls, and why its effects stay within that capability. Reword the Problem section to state expected behavior and a reproduction path. Confirm the model and harness line at the end of the description, in the form the template asks for.

Apply the switch to existing Claude sessions.
serverUpdateSettings updates settings but does not close the affected provider sessions. Reconciliation replaces the provider instance, but existing sessions use a separate session scope and ProviderSessionManagerV2.open returns an existing runtime without reopening the adapter. That runtime keeps the old promptSuggestions value, so disabling the switch can still generate suggestions in an existing thread.
Close or refresh affected sessions when the setting changes, and add a focused regression test.

Not changing this. Like every provider setting (launch args, binary path, auto-compact window), the Labs flag applies when a provider session opens, and the Labs row says "Applies to new sessions." Settings updates never close running sessions; serverUpdateSettings does not call closeInstance. Applying one flag mid-thread would mean restarting the Claude query.
@t3dotgg You're right. openSession captures the flag, which matches the Labs row’s “Applies to new sessions” contract. I incorrectly treated the lack of an update to existing sessions as a defect. I withdraw this finding; no session restart or regression test for immediate application is needed.
I couldn't check this conversation for new learnings, so no new learning was saved.

Do not offer a Tab-only suggestion on touch-only mobile web.
When the mobile composer expands, this condition can offer the suggestion and display a “⇥ Tab” hint. A user with only a software keyboard has no tap action to accept it. Hide the offer on that surface until it has a tap action, or add one. (raw.githubusercontent.com)

Fixed in 11fd8e9. The composer now skips the suggestion when useMediaQuery({ pointer: "coarse" }) matches, so touch-only screens get neither the hint nor Tab acceptance. A tap control is a follow-up, together with the mobile app.
@t3dotgg The supplied code confirms that !coarsePointer gates both the suggestion hint and Tab acceptance. This addresses the finding. The tap control can remain a follow-up.

Bound the best-effort sample request.
If thread/sample does not answer, its fork remains pending until the session scope closes. Repeated completed turns can accumulate pending requests. Apply a timeout before Effect.forkIn(scope) so a stalled experimental endpoint releases each request. As per coding guidelines, “Make sure all changes are considerate of performance impact.”

Codex already bounds this on its side. thread/sample gives up after SAMPLE_TIMEOUT (30s) in codex-rs/app-server/src/thread_sample.rs and answers with an error, so each fork ends. Versions without the method answer method-not-found right away.
@t3dotgg Thanks for the correction. I missed Codex’s server-side timeout. With SAMPLE_TIMEOUT returning an error after 30 seconds, the existing Effect.catchCause handles that failure and the fork ends. The unbounded-request concern does not apply, so I withdraw this finding. No change is needed here.

Skip sampling while descendant work is active.
If a root turn completes while a subagent is still running, retainSettledContext can be false because it checks work retained for the root turn. This branch then samples before the subagent finishes, although the prediction is intended for a finished run. Include active descendants in the eligibility check.

This is intended. The composer shows a suggestion only when its runId is the thread's latest run and that run is completed (usePromptSuggestion.ts). A suggestion sampled while child work runs stays hidden until the run finishes. Waiting for descendants here would skip every turn that leaves work running.
@t3dotgg You're right. I conflated suggestion generation with suggestion display. usePromptSuggestion.ts requires a matching latest runId and a completed run before it returns the suggestion. Adding a descendant check here would skip sampling, not defer it. I withdraw this finding. No change is needed.

Clear prompt suggestions when thread.deleted is committed.
subscribePromptSuggestion reads the cached value by thread ID and performs no existence or per-thread access check. AuthOrchestrationReadScope is the only authorization gate for this RPC. A client that knows a deleted thread ID can therefore still receive its cached suggestion until eviction or restart.
Connect cache invalidation to the thread.deleted handling owned by the orchestration deletion flow. Remove the parent and cascaded side-chat IDs from the ProviderSessionManager cache. Do not add this side effect to the pure ThreadDeletion.ts planner.

Fixed in 11fd8e9. subscribePromptSuggestion now reads the thread before emitting each suggestion and sends null for a missing or deleted thread, so neither open nor new subscribers get it. The test "stops serving prompt suggestions once a thread is deleted" covers a late suggestion after deletion. Clearing on detach was not enough: deletion skips stopped sessions, and a late Codex sample could add the entry back.
@t3dotgg The supplied implementation addresses this finding. subscribePromptSuggestion checks the thread before emitting a non-null suggestion and returns null for deleted threads or failed lookups. This also prevents delivery when a late Codex sample repopulates the cache.
The read-time check is a valid alternative to deletion-time cache invalidation.

When native event logging is configured, enabling promptSuggestions causes the SDK’s prompt_suggestion frame to be written to a retained log before this adapter handles it. shouldPersistProviderEvent does not exclude that frame.

Not changing this. The native event log is an opt-in diagnostic log that already stores every user prompt and full assistant message for the thread, so a one-line suggestion frame adds no new kind of exposure. "Not persisted" in this PR means the orchestration database and projections, which never see suggestions. The filter in shouldPersistProviderEvent exists to drop high-volume token deltas for log size.
@t3dotgg Understood. I conflated orchestration persistence with opt-in diagnostic logging. With that scope clarified, retaining prompt_suggestion frames in the native event log does not violate the intended behavior. I withdraw this finding. No filter change is needed.

Already covered. This review was of fa24347. 11fd8e9 added "ProviderSessionManagerV2 stops serving prompt suggestions once a thread is deleted", which drives subscribePromptSuggestion through its initial null, a delivered suggestion, and deletion with a late suggestion. Not adding eviction or isolation cases: the store is a plain per-thread map.

@t3dotgg Confirmed in ProviderSessionManager.test.ts: the test covers the initial null, a delivered suggestion, and null after deletion with a late suggestion. My claim that the subscription path had no coverage is outdated.
I withdraw the request for additional isolation and eviction cases. I inspected the test but did not run it.

Allow keyboard users to dismiss the suggestion.
When a suggestion is visible, Tab inserts it instead of moving focus. A keyboard user cannot move forward from an empty composer without changing the draft. The editor prevents the default Tab action. (raw.githubusercontent.com)
Allow Escape to dismiss the suggestion so the next Tab moves focus.
Based on learnings, “interactive elements need logical keyboard access.”

Fixed in be059be. Escape in an empty composer now dismisses the current run's suggestion, so the next Tab moves focus. Escape skips IME composition first. I checked it in a dev server: suggestion shown, Escape brings back the default placeholder, Tab moves focus to "Attach files", and the composer stays empty.
@t3dotgg Thanks. The Escape handler now checks IME composition before dismissing the suggestion without changing the draft. Your dev-server check confirms that the next Tab moves focus to “Attach files.” This addresses the finding.
I couldn't check this conversation for new learnings, so no new learning was saved.

Skip sampling while root-owned background work remains.
If a root turn completes while its background command or MCP app capture is still running, retainSettledContext is true, but this condition still sends thread/sample. The request consumes a cached sample before that work finishes. Require !retainSettledContext here and cover this case in the replay test. This is separate from the previously reported active-descendant case. As per coding guidelines, “Make sure all changes are considerate of performance impact.” (raw.githubusercontent.com)

Not changing this. An earlier review removed that guard on purpose: turns that leave a background command running, such as a dev server, are common, and with the guard they never got a suggestion. The composer shows a suggestion only once its run is completed, so a sample taken while the command runs stays hidden until then. Each sample is one low-effort cached request either way.
@t3dotgg Understood. I withdraw this finding. retainSettledContext preserves late background events; it does not make the completed root turn ineligible for a suggestion. Adding !retainSettledContext would suppress suggestions for long-running commands, not defer them, because releaseSettledTurnIfIdle does not sample again. The composer’s completed-run check controls when the suggestion appears. No change is needed for this finding.

Guard stale prompt-suggestion events before replacing the per-thread value.
Each completed root run forks an independent sample request. If the newer run's sample completes first, a late response from the older run overwrites the newer entry because ProviderSessionManager performs an unconditional replacement. The web hook then rejects that older runId, so the latest completed run displays no suggestion.
Add a shared per-thread ordering guard at the producer or store. Accept an event only when its run is still the latest completed run, or when it carries a newer per-thread sequence.

Not changing this. Codex already orders these. thread/sample compares the parent history revision before and after the sample and fails with "sample source changed" when a newer turn has started (codex-rs/app-server/src/thread_sample.rs, the history_version() check after cleanup). A late sample from an older run therefore errors, and samplePromptSuggestion drops it. A sample that finishes before the next turn starts is emitted before that turn exists, so it cannot overwrite a newer suggestion. The client also shows a suggestion only for the latest completed run.
@t3dotgg Understood. My finding did not account for Codex’s history_version() validation. The "sample source changed" error prevents the stale response described in my finding, and samplePromptSuggestion catches that error without emitting an update.
I withdraw the finding. No additional ordering guard is needed for this scenario.

Independent verification performed on November 4, 2026, of PR #28047 at a66caa6983c37745c92bb0c6e9387267ea76ab5e on macOS arm64, using the web client at 1280×800 and Codex CLI 0.166.0 signed in with ChatGPT.
I checked the unmodified PR head in a separate worktree with isolated .t3 state. Two disposable test threads used real gpt-6-luna turns; their thread/sample responses produced different suggestions. No suggestion or provider response was injected.
Verified:
Focused existing tests:
| 1 | vp test run apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts apps/server/src/orchestration-v2/ProviderSessionManager.test.ts -t 'suggestion' |
Result: 10 passed across 3 files. 468 other tests were excluded by the name filter. No repo-wide suite was run.
No defect was confirmed in these scenarios, and no source changes were needed. This is a focused validation result, not approval to merge.
Limits: real Claude sessions, packaged Electron, mobile, remote/relay/tunnel connections, IME and overlapping-turn races were not manually tested. The test threads were created by the development server CLI and are displayed as agent-authored initial messages. The web composer displayed its existing Astra draft selection; persisted runs and provider requests confirm both executed test turns used gpt-6-luna. This validation does not assess that separate selection behavior.
Evidence:
The recordings are accelerated and cropped to the conversation/composer area to exclude the machine label and sidebar. The draft text and interactions are unmodified. Original full-window screenshots and recordings remain private. The public bundle omits local paths and internal request, thread and response identifiers.
