It tells the model what the objective +is and how to deliver it. It says nothing about two things the model has no +other cheap way to know. + +**How much of the window is left.** A Goal stops when `tokensUsed` reaches +`tokenBudget`, 30,000,000 by default, and gets one wind-down turn to hand off. +Until that turn arrives the model has no signal at all: it cannot tell turn 3 +of a long run from the turn before the budget stops it, so it cannot choose +between starting a broad investigation and finishing what it has. `get_goal` +can supply the figures, but asking on every turn would spend an extra tool call +to obtain context the runtime already holds when it schedules the turn. + +**Whether the last turn accomplished anything.** The verifier only ever sees a +terminal proposal. A turn that proposes nothing is judged by nobody -- and a +turn spent restating status is exactly the turn that proposes nothing. Nothing +in the prompt asks the model to notice that its previous turn changed nothing +and to do something different. + +Codex's continuation template runs to 56 lines and covers both: a budget block +with the same figures, plus work-from-evidence, no-progress, fidelity, and +completion-audit sections. Claude Code has no equivalent; its Stop hook feeds +back a refusal reason instead. + +## Design + +Two additions to the one place every host renders from. + +**A token-budget line**, when the runtime supplies figures: what has been +spent, out of what, how much remains, and how many turns are behind it. Spelled +out with locale grouping rather than abbreviated, since a prompt is read once +by a model and not squeezed into a footer. + +It sits after the standing objective guard and before the objective-updated +notice. The figures are context for the whole turn; the notice is about what +changed since the last one and reads last so it is acted on last. + +It stays out of the data block deliberately. The line contains trusted runtime +figures, while the block is explicitly framed as untrusted task data. Keeping +the line outside preserves that trust boundary. + +The remainder is clamped at zero. The wind-down turn runs with the window +already overspent, and a negative remainder would read as nonsense on the one +turn the figures matter most. + +**Four progress lines**, on every turn except the hand-off. They ask the model +to treat the workspace rather than the conversation as authoritative, to work +toward the end state the objective asks for rather than a more easily reached +one, to judge whether its previous turn actually changed anything before +spending this one, and to check every explicit requirement against citable +evidence before proposing completion. + +They are skipped on the wind-down turn, which is told not to start new work: a +line asking for "a different concrete action now" would contradict it. The +token-budget line is kept there, because a hand-off reports the numbers it +stopped at. + +The judge-your-previous-turn line is also held back on the Goal's first turn. +`create` schedules a continuation before any Goal turn has finished, so on +that one turn there is no previous turn to judge, and asking for the judgement +invites the model to describe one. A host that reports no figures at all says +nothing about which turn this is, so the line stands there: silence is not +evidence of a first turn. + +**Where the figures come from.** `GoalTurnHost.startGoalTurn` gains an optional +`usage`, and `flushContinuation` reads it off the record at scheduling time, +before the broadcast hands listeners a snapshot they may act on. The shared +`GoalContinuationUsage` type projects the three fields from `GoalRecord`, so +the runtime and renderer cannot drift into different shapes. The three hosts +copy it into their queue entries alongside the fields they already copy, and +pass it to the renderer. User-driven turns never render this prompt, so they +never carry figures. + +`usage` remains optional on the public host and renderer contracts for +embedders that have no runtime figures. Its absence omits only the token-budget +line; the progress guidance still renders on non-wind-down turns. + +## Scope + +- `goal-continuation-prompt.ts`: the shared `usage` type, renderer input, + `renderBudgetLine`, the four progress lines, their placement and their two + exceptions, and the `buildGoalContinuationParts` pass-through. +- `goal-runtime.ts`: the `usage` field on the host contract, and reading it off + the record in `flushContinuation`. +- `useMessageQueue.ts` and `use-llm-stream.ts`, `Session.ts`, + `nonInteractiveCli.ts`: one field copied through each host's queue entry. +- `docs/users/features/goals.md`: what each continuation turn now tells the + model. + +Not changed: the `get_goal` and `update_goal` tool descriptions; the blocked +audit, which qwen already runs as a three-turn fingerprint check in the +runtime rather than as prompt text; and the runtime's own bounds, which are +separate work. + +## Verification + +- `goal-continuation-prompt.test.ts`: complete-string expectations pin both + the ordinary production shape with usage and the wind-down shape.

H Once a Goal has billed a turn, the footer pill and every status card show what it has spent against the window it is allowed, as `1.2k/30.0m`. The figure counts the model calls the Goal makes in its own turns; subagents and the verifier's own checks are not included. The window is set by [`model.goalTokenBudget`](../configuration/settings.md); resuming a Goal that has spent its window grants another one on top of what it has already spent, so the figure reads `30.0m/60.0m` rather than starting over. A Goal with no budget shows only what it has spent. A Goal that has not billed a turn yet shows no figures at all. +Each turn the session takes on its own reports what the Goal has spent so far, how many turns are behind it, and — unless the Goal runs unbounded — the window it is allowed. Every such turn except the final wind-down hand-off also carries standing instructions to re-check the workspace rather than trust earlier turns' reports, to work toward the end state the objective asks for, to do something different when the previous turn changed nothing (from the second turn on, once there is a previous turn to judge), and to check every requirement against citable evidence before proposing that the Goal is done. + A long Goal periodically compresses the evidence it has recorded into checkpoint claims with a side model call, so later turns and the verifier still have it to cite. That call is bounded by [`model.goalCheckpointTimeoutSeconds`](../configuration/settings.md), 180 seconds by default; a checkpoint that does not finish in time is abandoned as an inconclusive check — the checkpoint stall streak is preserved rather than incremented — and a later turn retries it. The call is streamed, so the per-request transport timeout bounds only connect and first response, and the ceiling itself stops at the stream guards' 15-minute lifetime cap because past that the guard, not the setting, ends the call. That 15-minute limit on the setting is fixed, and raising the stream guard's own cap does not lift it. ## Interrupting a Goal diff --git a/packages/cli/src/acp-integration/session/Session.test.ts b/packages/cli/src/acp-integration/session/Session.test.ts index fd249ac59bc..868eee7de53 100644 --- a/packages/cli/src/acp-integration/session/Session.test.ts +++ b/packages/cli/src/acp-integration/session/Session.test.ts @@ -24386,6 +24386,61 @@ describe('Session', () => { ); }); + it('carries the spend figures into the continuation prompt', async () => { + // `usage` is optional on both sides of the host hop, so a dropped + // copy typechecks and shows up only as a prompt that lost its budget + // line on this host. + const permit: core.GoalTurnPermit = { + goalId: 'goal-1', + revision: 1, + turnId: 'turn-usage', + }; + mockGoalRuntime.getSnapshot.mockReturnValue({ + v: 2, + activity: 'running', + goal: { + goalId: 'goal-1', + revision: 1, + objective: 'check weather', + status: 'active', + evidenceCursor: { recordId: 'cursor-1' }, + turnCount: 4, + activeTimeMs: 0, + tokensUsed: 1_234, + createdAt: 1234, + updatedAt: 1234, + }, + }); + mockGoalRuntime.permitForTurn.mockImplementation((turnKey: string) => + turnKey === 'goal-runtime:turn-usage' ? permit : undefined, + ); + mockChat.sendMessageStream = vi + .fn() + .mockResolvedValue(createEmptyStream()); + + expect(boundGoalHost).toBeDefined(); + await boundGoalHost!.startGoalTurn({ + permit, + continuationContext: 'check weather', + usage: { tokensUsed: 1_234, tokenBudget: 30_000_000, turnCount: 4 }, + }); + + await vi.waitFor(() => { + expect(mockChat.sendMessageStream).toHaveBeenCalled(); + }); + const request = (mockChat.sendMessageStream as ReturnType) + .mock.calls[0]?.[1] as { message: Array> }; + expect( + request.message.some( + (part) => + typeof part['text'] === 'string' && + (part['text'] as string).includes( + 'Token budget: 1,234 of 30,000,000 tokens used, 29,998,766 remaining; 4 Goal turns finished.', + ), + ), + ).toBe(true); + }); + it('settles a Goal turn whose prompt rejects before the turn body runs', async () => { // `prompt()` rejects ahead of the try whose finally settles the turn // when `assertCanStartTurn` throws — a session that began closing diff --git a/packages/cli/src/acp-integration/session/Session.ts b/packages/cli/src/acp-integration/session/Session.ts index 7bf60aa0692..cc69e1aac6a 100644 --- a/packages/cli/src/acp-integration/session/Session.ts +++ b/packages/cli/src/acp-integration/session/Session.ts @@ -41,6 +41,7 @@ import type { GoalSnapshotV2, GoalStateCause, GoalTurnHost, + GoalContinuationTurn, GoalTurnPermit, ToolCallRequestInfo, ToolCallResponseInfo, @@ -615,15 +616,11 @@ type BeforeModelSendContext = { compressionFailed: boolean; }; -interface AcpGoalTurn { +interface AcpGoalTurn extends GoalContinuationTurn { permit: GoalTurnPermit; turnKey: string; controller: AbortController; origin: 'runtime' | 'user'; - continuationContext: string; - objectiveUpdated?: boolean; - windDown?: boolean; - verifierFeedback?: string; modelStarted: boolean; } @@ -2305,19 +2302,13 @@ export class Session implements SessionContext { ) { return; } + const { permit, ...continuation } = input; this.goalQueue.push({ - permit: { ...input.permit }, - turnKey: `goal-runtime:${input.permit.turnId}`, + permit: { ...permit }, + turnKey: `goal-runtime:${permit.turnId}`, controller: new AbortController(), origin: 'runtime', - continuationContext: input.continuationContext, - ...(input.objectiveUpdated - ? { objectiveUpdated: input.objectiveUpdated } - : {}), - ...(input.windDown ? { windDown: true } : {}), - ...(input.verifierFeedback - ? { verifierFeedback: input.verifierFeedback } - : {}), + ...continuation, modelStarted: false, }); void this.#drainGoalQueue(); diff --git a/packages/cli/src/nonInteractiveCli.test.ts b/packages/cli/src/nonInteractiveCli.test.ts index 8acb0e9d183..813887edc93 100644 --- a/packages/cli/src/nonInteractiveCli.test.ts +++ b/packages/cli/src/nonInteractiveCli.test.ts @@ -1295,6 +1295,39 @@ describe('runNonInteractive', () => { ); }); + it('carries the spend figures into a scheduled Goal continuation', async () => { + // The host copies `usage` onto its own turn record.
