goal-mode support and harden behavior that can only be judged after the full loop exists. + +This phase is complete when goal mode can run in a headless command path with machine-readable outcome data, and the implemented feature has explicit decisions for stale reminders, repeated injections, vague-goal intake, and budget behavior. + +## Background + +Phases 1a through 5 build the interactive goal mode. +They store durable state, expose user controls, inject goal context, account usage, continue automatically, run an evaluator, and verify the full TUI flow. + +The research review also identified non-interactive goal mode as part of mature `/goal` behavior. +This repository already has CLI prompt paths under `apps/kimi-code/src/cli`. +Those paths need separate planning because they do not share the TUI slash-command loop. + +## Reason + +Goal mode is most useful for long-running work and CI-style checks. +Interactive-only support leaves out the headless use case. + +Some behavior also needs real-session evidence: + +- repeated `GoalInjector` reminders +- repeated `goal_continuation` prompts +- stale historical reminders after resume +- vague or non-verifiable goals +- evaluator strictness +- evaluator model choice +- budget defaults and budget stop wording +- terminal snapshot retention +- context-clear behavior while a goal exists + +This phase keeps those concerns visible without blocking the first working interactive implementation. + +## Concrete Changes + +Add a headless goal entry point in the existing CLI prompt path. +Use the existing `apps/kimi-code/src/cli` structure rather than creating a second runtime. + +The headless path shall support a command equivalent to: + +```text +kimi -p "/goal " +``` + +or the nearest existing prompt-mode syntax in this repository. + +It shall: + +- create or resume a session +- parse the `/goal` command with the same objective cap and budget options as the TUI +- treat a resumed stale active goal as paused unless the headless invocation explicitly asks to resume it +- start the main-agent turn +- wait for the goal to reach a terminal state +- stream normal assistant output +- emit a final machine-readable goal summary when requested +- return distinct exit codes for success, blocked, impossible, budget-limited, interrupted, and error + +Add goal events to the SDK event stream

stale budget numbers confusing the model, design a replacement strategy: + +- either replace the previous goal reminder instead of appending each step +- or keep appending but make the reminder explicitly say it is a fresh runtime snapshot + +Review continuation prompt history. +`GoalContinuationController` appends `goal_continuation` user messages as real conversation history. +Long goals can produce repetitive replay history. +Decide whether to accept this transcript growth, summarize old continuation prompts during compaction, or replace continuation prompts with a lighter internal marker. + +Review vague-goal intake. +Phase 3 gives the model a `CreateGoal` tool and a well-formedness rubric. +The TUI `/goal` path in Phase 2 remains deterministic. +After dogfooding, decide whether `/goal ` should stay deterministic or become model-assisted intake: + +- deterministic create is faster and predictable +- model-assisted intake catches vague, compound, or non-goal input before state is created + +If model-assisted intake is adopted, add a new phase rather than changing Phase 2 in place. +That phase should route `/goal ` to a structured intake prompt and let `CreateGoalTool` create the state only when the objective is well formed or the user insists. + +Review hard budget defaults. +Confirm whether `DEFAULT_GOAL_TURN_BUDGET` is enough as the default safety cap. +Decide whether to add default token or wall-clock budgets in config. + +Review evaluator model choice. +Phase 4d uses the main agent `llm` first, with a constructor seam for a future judge model. +Decide whether to add a config field for a small or fast evaluator model after measuring cost and judgment quality. + +Review terminal snapshot retention. +Terminal goals intentionally remain in `state.json` until `/goal clear` or replacement. +Decide whether to keep that indefinitely, expire terminal snapshots after a bounded number of resumes, or archive the last terminal summary somewhere outside `metadata.custom.goal`. + +Review context clear behavior. +Kimi goal state lives in `Session.metadata.custom.goal`, so clearing agent context does not automatically clear the goal. +Decide whether the existing context-clear command should clear, pause, or leave goals alone. +If it leaves goals alone, document the difference from agents where `/clear` also clears the active goal. + +Review blocked behavior. +Confirm that terminal `blocked` state, reason, evidence, and `/goal` status give enough user feedback. +If not, add a user-visible notice event or a TUI panel. + +## Tests + +Add headless integration tests near the existing CLI prompt tests. + +The tests shall cover: + +- headless `/goal` creates a goal and waits for terminal `complete` +- headless `blocked`, `impossible`, `budget_limited`, `interrupted`, and `error` outcomes return distinct exit codes +- optional machine-readable summary includes goal id, status, reason, budgets, and evidence +- disabled `goal-command` flag treats `/goal ...` as ordinary prompt text or returns the existing feature-disabled behavior +- headless runs preserve `goal.*` audit records + +Extend `packages/agent-core/test/harness/goal-session.test.ts` or add adjacent focused tests for hardening items: + +- replayed historical goal reminders do not create new `GoalInjector` output without an

contract or handled by the chosen compaction or dedupe strategy +- terminal `blocked` status retains reason and evidence across resume +- budget wrap-up text runs once +- `DEFAULT_GOAL_TURN_BUDGET`

The high-level shape agrees. The +internals, however, diverge in ways that will ripple through later phases. + +### Findings + +**❌ 1. SDK/RPC exposure is front-loaded on Branch 2.** +Branch 2's Phase 1a already edits `rpc/core-api.ts` and `rpc/core-impl.ts` to expose +`createGoal/getGoal/pauseGoal/resumeGoal/cancelGoal/clearGoal` on `SessionAPI`. Branch 1 +keeps Phase 1a as a pure store + session wiring and defers all SDK exposure to **Phase 2** +("expose goal lifecycle via SDK and wire the /goal slash command"). Not a bug, but the +phase boundaries differ — Branch 2's Phase 2 will likely look smaller / different. Worth +watching that Branch 2 doesn't *also* re-touch these files in its Phase 2. + +**❌ 2. `GoalSnapshot` is a fundamentally different type.** +- Branch 1: a *flattened, computed* view — all goal fields hoisted to the top level + plus a nested `budget: GoalBudgetReport` (remaining/limits/`*Reached`/`overBudget`). + Also exposes `GoalBudgetReport`, `isTerminalGoalStatus()`. +- Branch 2: a *wrapper* — `{ goal: SessionGoalState | null, remainingTokens, overBudget, + tokenBudgetReached, turnBudgetReached, wallClockBudgetReached }`. No `GoalBudgetReport` + type; no `remainingTurns` / `remainingWallClockMs`; budget limits stay nested under + `goal.budgetLimits`. + +This is the biggest divergence. Every downstream consumer (slash command output, model +tools, continuation controller, evaluator, headless summary) reads the snapshot, so the +two branches' later phases will not be line-comparable here. Branch 2 also drops the +distinction between `GoalToolResult` (`{goal: SessionGoalState|null}`) and the snapshot. + +**❌ 3. `recordModelReport` loses dedicated fields on Branch 2.** +Branch 1 stores `lastModelReportStatus`, `lastModelReportReason`, `lastModelReportEvidence` +as first-class state fields and never changes status (it records the model's *requested* +terminal state as evidence for the continuation controller / evaluator to act on). +Branch 2 drops those three fields entirely and instead appends an entry to `lastEvidence` +(`{ kind: 'model_report', summary: ": " }`). Branch 1's Phase 4c/4d +continuation+evaluator logic keys off `lastModelReportStatus`; if Branch 2 keeps this +shape it will need a different continuation strategy. **Track whether Branch 2's later +phases can recover the requested status from a stringified evidence summary.** + +**⚠️ 4. `GoalEvidence` shape differs.** +- Branch 1: `{ summary, detail?, source? }`. +- Branch 2: `{ kind, summary }`. +Both persist in the durable record, so they are not interchangeable across branches. + +**⚠️ 5. `GoalActor` typing.** +Branch 1 defines a typed union `'user'|'model'|'evaluator'|'continuation'|'runtime'|'system'` +and threads it through every input. Branch 2 uses plain `string` for `actor` and hard-codes +literals (`'user'`, `'runtime'`, `'model'`, `'evaluator'`) at call sites. Branch 2 loses +compile-time actor validation. + +**❌ 6. Store ownership model: callbacks vs cached state.** +- Branch 1: stateless store over `readState()` / `writeState()` callbacks — metadata is the + single source of truth, re-read on every operation, and `writeState` is **awaited**. +- Branch 2: caches `this.state` in memory, reads metadata only in the constructor, and + persists via fire-and-forget **`void this.persist()`** (sync methods). + +Risks on Branch 2: (a) if session metadata is mutated elsewhere, the cached `this.state` +goes stale; (b) fire-and-forget writes are not ordered/awaited, so a crash or a rapid +create→update sequence can lose or reorder a persist; (c) `createGoal` etc. are synchronous +and return before the write lands. Branch 1's awaited model is safer. + +**❌ 7. Usage deltas are not clamped on Branch 2.** +Branch 1 clamps with `Math.max(0, input.tokenDelta)` / `Math.max(0, input.wallClockMs)`. +Branch 2 adds the raw delta (`current.tokensUsed + input.tokenDelta`), so a negative delta +would *decrement* recorded usage. Minor but a real defensiveness gap. + +**⚠️ 8. Goal ID generation.** +Branch 1: `randomUUID()`. Branch 2: `goal-${Date.now()}-${counter}` with a module-level +counter that resets per process. Fine within a session, but not globally unique and not +collision-proof across restarts within the same millisecond+counter window. + +**⚠️ 9. `incrementTurn` actor.** +Branch 2 sets `updatedBy: 'runtime'` and overwrites `lastEvidence` with the (possibly +undefined) input evidence on every turn; Branch 1 only sets `lastEvidence` when provided. +Branch 2 can therefore clear previously recorded evidence on a bare `incrementTurn()`. + +**✅ 10. Shared, consistent pieces.** +`errors/codes.ts` goal error codes are identical (51 added lines on both). `GoalStatus` +union, `GoalBudgetLimits`, `DEFAULT_GOAL_TURN_BUDGET = 20`, `MAX … = 4000`, the +create-with-`replace` guard, and pause/resume/cancel/clear semantics all agree at the +behavioral level. + +### Net assessment for Phase 1a +Same architecture and intent, but **not drop-in compatible**: the snapshot type, evidence +shape, model-report storage, and persistence model differ enough that downstream phases +will diverge structurally. The items most likely to become *functional* problems later +are #3 (model-report fields the continuation/evaluator need) and #6 (fire-and-forget +persistence). Everything else is stylistic or a minor robustness gap. + +--- + +## Phase 1b — goal audit records, replay ignore, resume normalization + +| | Branch 1 (`70ee3c6`) | Branch 2 (`cc1f6c8`) | +|---|---|---| +| Files | records/index.ts, records/types.ts, goal.ts, session/index.ts, 2 tests, TRACKER.md | same minus TRACKER.md | + +**This phase converges strongly.** Both branches independently arrived at the same design: + +- **✅ Audit-only goal records.** Identical taxonomy — `goal.create`, `goal.update`, + `goal.account_usage`, `goal.continuation`, `goal.report`, `goal.evaluate`, `goal.clear` — + and both wire them into `restoreAgentRecord` as **replay-ignored** (goal state is restored + from `metadata.custom.goal`, never rebuilt from records). Same architectural decision. +- **✅ `normalizeMetadata` resume semantics match exactly:** drop malformed goals, drop a + stale `cancelled` goal (clear didn't complete), convert `active` → `paused` with + reason `"Paused after session resume"` and emit a `goal.update` audit record, leave + `paused`/terminal goals intact. +- **✅ Pending-records queue + flush pattern matches:** both buffer audit records emitted + before the main-agent sink exists and flush via `flushPendingRecords()`; both wire the + sink as `() => this.agents.get('main')?.records` and flush around `normalizeMetadata`. + +### Findings (divergences, all minor) + +**⚠️ 1. Async vs sync, again.** Branch 1's `normalizeMetadata` is `async` and awaits each +write; Branch 2's is sync with `void this.writeMetadata()`. Same behavior, same persistence +risk already noted in Phase 1a #6. + +**⚠️ 2. Record type fidelity.** Branch 1's record event types reuse the strong +`GoalActor / GoalBudgetLimits / GoalEvidence / GoalStatus` types from `session/goal`. +Branch 2 declares them loosely (`status: string`, `actor: string`, +`budgetLimits: Record`, inline `{ kind; summary }[]`). Consistent with the +Phase 1a typing divergence; no functional impact but weaker type-safety on the audit path. + +**⚠️ 3. `goal.account_usage` record shape differs.** +- Branch 1: discriminated — `usageKind: 'token' | 'wall_clock'` + `delta` + both + `tokensUsed`/`wallClockMs` snapshots + optional `source`. +- Branch 2: no discriminant; distinguishes by which optional field is present + (`tokensUsed?` vs `wallClockMs?`), `source` is required, and the wall-clock record passes + the **sentinel** `source: 'wall_clock'` rather than a real source. Slightly hacky but works. + +**⚠️ 4. `goal.create` / `goal.clear` record fields.** Branch 1's `goal.create` carries +`actor`; Branch 2 carries `completionCriterion` instead (no actor). Branch 1's `goal.clear` +carries `actor` + `reason`; Branch 2's carries only `goalId`. Branch 2's records are +lighter and lose the actor attribution that Branch 1 keeps end-to-end. + +**⚠️ 5. Validation helper.** Branch 1 factors a reusable `isValidGoalState()`; Branch 2 +inlines the check against a `validStatuses` array. Cosmetic. + +### Net assessment for Phase 1b +The hard part — deciding records are audit-only and getting resume normalization right — is +**implemented the same way on both branches**. Remaining differences are the same +typing/async stylistic gaps already flagged in Phase 1a, plus lighter audit-record payloads +on Branch 2 (notably the dropped `actor` attribution).

No `GoalBudgetReport`, + `remainingTurns`, or `remainingWallClockMs`. Downstream consumers will read goal fields + via `snapshot.goal.*`, not top-level. Same structural break flagged for Branch 2. +- ❌ **Dropped `lastModelReportStatus/Reason/Evidence` state fields.** `recordModelReport` + folds the report into `lastEvidence` as + `{ description: "Model report: ", source: 'model_report' }`. Branch 1's + continuation/evaluator (Phase 4c/4d) key off `lastModelReportStatus`; whether Branch 3 + can recover the requested status from this stringified evidence is the thing to watch in + its later phases. +- ⚠️ **`string` actors** (no `GoalActor` union) — loses compile-time actor validation. + +### Unique to Branch 3 +- ⚠️ **A third `GoalEvidence` shape:** `{ description, source? }`. + (Branch 1 = `{ summary, detail?, source? }`; Branch 2 = `{ kind, summary }`.) All three + branches picked a different evidence record — none are interchangeable. +- ⚠️ **`GoalToolResult` keeps both** raw + snapshot: + `{ goal: SessionGoalState | null, goalBudgetReport?: GoalSnapshot }`. +- ⚠️ **`record*` return types differ:** `recordTokenUsage/WallClock/incrementTurn/ + recordEvaluatorVerdict` return `void` (Branch 1 returned `GoalSnapshot | null`, + Branch 2 returned `GoalSnapshot`). Callers can't chain on the updated snapshot. + +### Findings / risks +- ❌ **Weakest goal-ID scheme of the three.** `goalId = \`goal-${Date.now()}\`` — no UUID + (Branch 1) and not even Branch 2's `-${counter}` suffix. Two goals created in the same + millisecond collide. Low probability, but the weakest of the three branches. +- ❌ **Usage deltas not clamped.** `tokensUsed += input.tokenDelta` / + `wallClockMs += input.wallClockMs` with no `Math.max(0, …)` (Branch 1 clamps). A negative + delta would decrement usage. Same gap as Branch 2. +- ⚠️ **Usage/turns accrue while `paused`.** `recordTokenUsage`, `recordWallClockUsage`, + `incrementTurn` guard on `isActiveOrPaused(status)`, so a paused goal keeps accruing + usage. Branch 1 (and Branch 2) only accrue while `active`. Possibly intentional, but a + behavioral difference worth confirming. +- ⚠️ **`recordModelReport` has no status guard.** It records even on a terminal goal + (only throws if no goal exists). Branch 1 required an active goal; Branch 2 returned + early when not active. +- ⚠️ **`budgetLimits` spread ordering bug-risk.** `{ turnBudget: input… ?? DEFAULT, + ...input.budgetLimits }` — because `...input.budgetLimits` is spread *last*, an explicit + `turnBudget: undefined` in the input would overwrite the defaulted value back to + `undefined`, defeating the safety cap. Branch 1/2 set `turnBudget` last so the default + always wins. Only triggers if a caller passes an explicit `undefined`. + +--- + +## Phase 1b — goal audit records + resume normalization (`94a7f83`) + +Files: `records/index.ts`, `records/types.ts`, `session/goal.ts`, `session/index.ts`, test. + +### What matches (converges with Branch 1) +- ✅ **Audit-only goal records with replay-ignore.** Same `goal.*` taxonomy + (create/update/account_usage/continuation/report/evaluate/clear) wired into + `restoreAgentRecord` as no-ops; goal state is restored from `metadata.custom.goal`, never + rebuilt from records. Same core decision as both other branches. +- ✅ **`normalizeMetadata` resume semantics match:** drop malformed, drop stale + `cancelled`, convert `active` → `paused` and emit a `goal.update` audit record, leave + paused/terminal intact. +- ✅ **Pending-queue + `flushPendingRecords()`** buffering before the main-agent sink + exists — same pattern as Branch 1. + +### Divergences +- ❌ **Audit records embed the whole `SessionGoalState`.** `goal.create` and `goal.update` + are `{ goal: SessionGoalState }` — the entire mutable record is snapshotted into each + record, rather than Branch 1's discrete typed fields (`goalId/status/actor/…`). Distinct + from Branch 2's loose discrete fields too. Replay ignores them, so this is an + audit-readability/size difference, not a correctness one — but `actor`/`reason` are no + longer top-level on the record (they live inside the embedded goal). +- ❌ **`goal.report` / `goal.evaluate` drop `evidence`.** Branch 3's records carry only + `{ requestedStatus, reason }` / `{ verdict, reason }`. Branch 1 (and Branch 2) include an + `evidence` array. The audit trail loses the evidence that motivated a report/verdict. +- ⚠️ **`goal.continuation` drops `goalId`** (`{ turnsUsed }` only); Branch 1 includes it. +- ⚠️ **`account_usage` shape** matches Branch 2 (presence of `tokensUsed?`/`wallClockMs?`, + required `source`, sentinel `source: 'wall_clock'` for wall-clock) rather than Branch 1's + discriminated `usageKind`+`delta`. +- ⚠️ **Resume actor label is `'system'`** (Branch 1/2 used `'runtime'`). +- ⚠️ **Weaker status validation in normalize.** Branch 3 checks only + `typeof goal.status !== 'string'`; Branch 1/2 validate against the known-status set, so a + bogus status string (e.g. `"foo"`) would survive Branch 3's normalization. +- ⚠️ **`normalizeMetadata` is sync and fire-and-forgets its writes** (`void this.setGoalData(…)`), + unlike the rest of Branch 3, which awaits — a small internal inconsistency. + +### Net assessment (Phases 1a–1b) +Branch 3 looks like the strongest of the two WIP attempts so far: it keeps Branch 2's +cleaner type layout while restoring Branch 1's safe, awaited, single-source-of-truth +persistence. The items most likely to bite later are the same Branch-2 lineage issues — +**the dropped `lastModelReport*` fields** (continuation/evaluator dependency, Phase 4c/4d) +and **the wrapper-snapshot break** — plus Branch 3's own weak goal-ID scheme and the +audit-record evidence/field losses. None are blocking at this stage. + +--- + +## Phase 2 — SDK API + `/goal` command surface (`9324015`) + +Files closely match Branch 1's Phase 2 (`c14b025`): same TUI command files +(`dispatch.ts`, `goal.ts`, `index.ts`, `registry.ts`), `flags/registry.ts`, RPC +(`core-api.ts`, `core-impl.ts`, `session/rpc.ts`), and node-sdk (`rpc.ts`, `session.ts`, +`types.ts`). Branch 3 additionally edits `agent-core/src/index.ts` (+23, re-exporting goal +types). Both gate the feature behind the same flag (registry diff is a comment-only +change, so the flag entry itself is effectively identical). + +### What matches Branch 1 +- ✅ **Same SDK session surface:** `createGoal / getGoal / pauseGoal / resumeGoal / + cancelGoal / clearGoal`. +- ✅ **Same RPC surface** on `SessionAPI` (create/get/pause/resume/cancel/clear). +- ✅ **Same `/goal` subcommand grammar:** `status` (default), `create`, `pause`, `resume`, + `cancel`, `clear`, plus `replace`. +- ✅ **`metadata.custom.goal` is reserved** on both — generic metadata updates that touch + `goal` are rejected with `GOAL_METADATA_RESERVED` and the existing goal is preserved. + +### Divergences / findings +- ❌ **`/goal create` ignores budget flags on Branch 3.** Branch 1 parses + `--max-tokens` / `--max-turns` / `--max-minutes` (and `tokenBudget`/`turnBudget`) from the + command text. Branch 3's parser returns `{ kind: 'create', objective: input }` — the + whole remainder is the objective, with no flag parsing — so a TUI user can only ever get + the default `turnBudget = 20`. Budgets are settable via the SDK (`createGoal({budgetLimits})`) + but **not** via the slash command. Functional gap vs Branch 1. +- ⚠️ **`getGoal` returns the wrapper snapshot.** Branch 1 returns `GoalToolResult` + (`{ goal: GoalSnapshot | null }`); Branch 3 returns `GoalSnapshot` (its + `{ goal, remainingTokens, … }` wrapper). Direct consequence of the Phase 1a snapshot-type + divergence; SDK consumers read different shapes. +- ⚠️ **Control payloads thread an explicit `actor`.** Branch 1 uses one shared + `GoalControlPayload` (`{ reason? }`) for pause/resume/cancel/clear and defaults the actor + internally. Branch 3 defines separate `Pause/Resume/Cancel/ClearGoalPayload`, each with + `actor: string` + `reason?`, and the SDK methods accept `{ actor?, reason? }` defaulting to + `'user'`. Branch 3 leaks the actor concept to SDK callers. +- ⚠️ **`replace` is a distinct parse `kind`.** Branch 3 parses `replace` as its own command + kind that maps to create-with-`replace:true`; Branch 1 folds it into `create` as a boolean. + Same outcome, different structure. +- ⚠️ **Metadata-reservation strictness.** Branch 1 rejects when the `goal` *key is present* + (`'goal' in patchCustom`); Branch 3 rejects only when `custom.goal !== undefined`, so a + patch carrying `goal: undefined`/`null` slips past the guard (though the existing goal is + then restored, so no data loss). +- ⚠️ **Test coverage.** Branch 1 adds a node-sdk `session-goal.test.ts` (72 lines); Branch 3 + has no SDK-layer goal test in Phase 2 (its added tests are TUI-command + resolve/registry). + +### Net assessment (Phase 2) +The user-facing and SDK surfaces line up well — same commands, same RPC/SDK methods, same +reservation guard. The one real functional gap is **budget flags not being parseable from +`/goal create`** on Branch 3. The rest are the expected downstream of earlier type choices +(wrapper snapshot, explicit actors) plus a thinner SDK test surface. + +--- + +## Phase 3 — model goal tools: `CreateGoal` / `GetGoal` / `UpdateGoal` (`727bcf9`) + +Both branches add the same three model-facing tools (`.ts` + `.md`), register them in +`tools/builtin/index.ts`, `agent/tool/index.ts`, and `profile/default/agent.yaml`. Branch 1 +also adds a `goal/shared.ts` helper (41 lines); Branch 3 has none. + +### The key semantic matches ✅ +**`UpdateGoal` is a *report*, not a status change, on both branches.** Both call +`store.recordModelReport({ requestedStatus, reason, evidence })` and explicitly do **not** +end the goal — the continuation controller / evaluator decide later. This is the most +important design decision in this phase and the two branches agree on it. + +### Divergences / findings +- ❌ **`CreateGoal` mis-attributes the actor on Branch 3.** Branch 1 passes + `actor: 'model'` so a model-initiated goal records `startedBy: 'model'`. Branch 3 forwards + `args` straight to `createGoal`, and `createGoal` (Phase 1a) hard-codes + `startedBy: 'user'`. So on Branch 3 **every goal looks user-started even when the model + created it** — audit/attribution inconsistency vs Branch 1. +- ❌ **`CreateGoal` schema omits two budget fields on Branch 3.** Branch 1's + `BudgetLimitsSchema` exposes all five limits (`tokenBudget`, `turnBudget`, + `wallClockBudgetMs`, **`noProgressTurnLimit`, `failureTurnLimit`**). Branch 3's schema + exposes only the first three, so the model cannot set no-progress / failure limits through + the tool (they exist on the type but aren't surfaced). Pairs with the Phase 2 finding that + `/goal create` can't set budgets either. +- ❌ **`recordModelReport` storage still lacks the structured requested-status (carried over + from Phase 1a).** Branch 1 stores `lastModelReportStatus/Reason/Evidence` as fields; Branch + 3 only appends `lastEvidence: { description: "Model report: ", source: 'model_report' }`. + The tool layer is consistent, but Branch 3's later continuation/evaluator phases will have to + recover the requested status by string-parsing that evidence entry. **Still the top thing to + watch in Phase 4c/4d.** Branch 3's `recordModelReport` also has no active-status guard. +- ⚠️ **Tool docs (`.md`) are much terser on Branch 3** — 3 lines each vs Branch 1's + 20 / 5 / 14 lines (`create` / `get` / `update`). Since the `.md` is the tool description the + model sees, Branch 1 gives the model substantially more guidance on when/how to use each + tool. Factual commit difference (not judging the runtime effect). +- ⚠️ **Wiring style differs.** Branch 1 constructs tools with the `Agent` and resolves the + store via `requireGoalStore(agent, name)` + `isGoalToolError` (the `shared.ts` helpers), + giving a uniform "goal feature disabled" error path. Branch 3 injects + `SessionGoalStore | undefined` directly and inlines the undefined-check / `KimiError` + handling in each tool. +- ⚠️ **Evidence shape** (`{description, source?}` vs `{summary, detail?, source?}`) and + **tool output** (raw wrapper snapshot vs `{ goal, goalBudgetReport }`) differ — both direct + consequences of the Phase 1a type choices. +- ⚠️ **Schema strictness.** Branch 1's zod schemas are `.strict()` (reject unknown keys); + Branch 3's are not. + +### Net assessment (Phase 3) +The load-bearing decision — model tools *report*, they don't terminate the goal — is +**implemented identically**. The notable regressions vs Branch 1 are concrete and small: +**model-created goals attributed to `user`**, and **`noProgressTurnLimit`/`failureTurnLimit` +not settable** by the model. The dropped structured model-report fields remain the one item +that could turn into a functional problem once the continuation controller and evaluator land. + +--- + +## Phase 4a — goal context injection / `GoalInjector` (`dc3f46a`) + +Both add `agent/injection/goal.ts` (a `DynamicInjector` subclass) and register it in +`injection/manager.ts`. This is the most substantively different phase so far — the two +branches took genuinely different approaches to *how often* and *what* to inject. + +### The big divergence: injection cadence +- **Branch 1 — inject the full reminder every active step.** `getInjection()` returns the + complete goal reminder whenever the goal is `active`; there is no throttling or + deduplication. Always fresh, simplest possible, but repeats the full block every model + step (more tokens). +- **Branch 3 — full/sparse/skip cadence with dedup.** `GoalInjector` computes a *variant* + from conversation history: + - first injection → **full**; + - a `user` message since last injection → **full** (re-prime); + - ≥ `GOAL_FULL_REFRESH_TURNS` (5) assistant turns → **full** refresh; + - ≥ `GOAL_DEDUP_MIN_TURNS` (2) assistant turns → **sparse** (short objective+progress); + - otherwise → **skip** (`null`). + + This is a deliberate anti-staleness / token-saving design: re-prime the full goal + periodically and after each user turn, with a lightweight reminder in between. It is the + more sophisticated of the two on the specific axis of *keeping the goal alive over many + turns*, where Branch 1 simply brute-forces it by always re-injecting in full. + +### Content differences +- ❌ **Prompt-injection hardening only on Branch 1.** Branch 1 wraps the objective in + `` / `` and explicitly tells the model + to treat it as *data, not instructions* that override system/developer/tool/permission + rules. **Branch 3 injects the raw objective as plain text** (`Objective: `) with no + untrusted framing — a security/hardening regression vs Branch 1. +- ⚠️ **Budget guidance differs.** Branch 1 emits 3-band guidance (within / ≥75% approaching / + ≥100% over, computed from the max budget fraction across turns+tokens+time). Branch 3 emits + budget *warnings* only at a single ≥80% threshold (per-budget), plus a "budget limit + reached" line in the sparse variant. +- ⚠️ **Branch 3 omits self-report / evaluator surfacing.** Branch 1's reminder includes + `Latest self-report: — ` (`lastModelReportStatus`) and + `Latest evaluator verdict: …`. Branch 3 surfaces neither — a direct consequence of having + dropped `lastModelReportStatus` in Phase 1a, so the model never sees its own last report + echoed back. +- ⚠️ Branch 1 also surfaces wall-clock elapsed with a `formatElapsed` helper and + remaining-budget figures; Branch 3 shows used/limit but not "remaining". + +### Wiring / gating +- ⚠️ **Branch 3 self-gates inside the injector:** `if (this.agent.type !== 'main') return` + and `if (!flags.enabled('goal-command')) return`. Branch 1's injector only checks store + presence + active status (main-only attachment / flag gating handled elsewhere; its + `manager.ts` change is larger, ~18 lines, vs Branch 3's +2-line registration). + +### Net assessment (Phase 4a) +This is a real design fork, not a stylistic one. **Branch 3's cadence system is arguably +better at the "don't let the model forget the goal" problem** — periodic full refresh + +re-prime after user turns + sparse in between — whereas Branch 1 keeps it simple by always +re-injecting. However, Branch 3 **drops Branch 1's `` prompt-injection +framing** (a hardening regression) and, because it has no `lastModelReportStatus`, cannot +echo the model's last self-report or the evaluator verdict back into context. Net: Branch 3 +is more refined on injection frequency, less hardened on injection content. + +--- + +## Phase 4b — goal token accounting in `TurnFlow.afterStep` (`4d2cfdf`) + +Both branches hook `agent/turn/index.ts` to charge goal token usage on every session agent +step, using the same basis: `recordTokenUsage({ tokenDelta: grandTotal(usage), agentType, +source: 'agent_step' })`. Branch 3 also revises `session/goal.ts` usage APIs. + +### Consistent ✅ +- Same accounting trigger (every agent step) and same delta (`grandTotal(usage)`) with + `source: 'agent_step'`. +- ✅ **Branch 3 fixed the paused-accrual issue flagged in Phase 1a.** It changed the guards in + `recordTokenUsage` / `recordWallClockUsage` / `incrementTurn` / `recordEvaluatorVerdict` + from `!isActiveOrPaused(status)` to `status !== 'active'`, so usage now accrues only while + the goal is `active` — matching Branch 1. + +### Divergences / findings +- ❌ **Branch 3's afterStep call is fire-and-forget.** Branch 1 `await`s + `recordTokenUsage(...)` inside the step (and guards on `getActiveGoal() != null` first). + Branch 3 calls `this.agent.goals?.recordTokenUsage({...})` **without `await`**. The method + itself awaits its own write, but because the turn flow doesn't await the method, the persist + isn't ordered against the rest of the step — rapid successive steps can interleave the + read-modify-write of `tokensUsed`. This is the same fire-and-forget theme that Branch 3 + otherwise avoids, re-appearing at this specific call site. +- ⚠️ **Branch 3 drops `agentId` from accounting.** Branch 1 adds an `agentId` getter + (`basename(homedir)`) and records it; Branch 3 made `agentId`/`agentType` optional on + `RecordTokenUsageInput` and passes only `agentType`. So Branch 3's `goal.account_usage` + audit records have no per-agent-id attribution. +- ⚠️ **Guard placement.** Branch 1 checks `getActiveGoal() != null` at the call site (skips + the call entirely when inactive); Branch 3 always calls and relies on the method's internal + `status !== 'active'` early-return. Equivalent outcome. +- (Aside: Branch 1's Phase 4b commit also contains a stray empty `packages/agent-code` path — + a Branch-1 artifact, irrelevant to Branch 3.) + +### Net assessment (Phase 4b) +Accounting semantics line up, and Branch 3 cleaned up its own earlier paused-accrual bug +here — a good sign it's self-correcting. The one real concern is the **non-awaited +`recordTokenUsage` in the hot turn path**, which can race the goal-state read-modify-write; +the dropped `agentId` is a minor audit-fidelity loss. + +--- + +## Phase 4c — `GoalContinuationController` autonomous loop (`815d00e`) + +Both add `agent/goal/continuation.ts` and rework `turn/index.ts` to drive autonomous +continuation after a stopped step. The control flow is structurally parallel — increment +turn, account wall-clock, accept a model terminal report, enforce hard budgets, reconcile +`maxStepsPerTurn`, otherwise append a continuation prompt and continue. + +### ⭐ The payoff of the Phase 1a `lastModelReportStatus` divergence +This is where the dropped field finally matters. + +- **Branch 1** reads it directly: + ```ts + if (goal.lastModelReportStatus === 'complete' | 'blocked' | 'impossible') { + await store.updateGoal({ status: goal.lastModelReportStatus, actor: 'continuation', + reason: goal.lastModelReportReason, evidence: goal.lastModelReportEvidence }); + return STOP; + } + ``` +- **Branch 3** has no such field, so it **reverse-engineers the status out of a formatted + evidence string**: + ```ts + const modelReportStatus = goal.lastEvidence?.find(e => e.source === 'model_report'); + if (modelReportStatus) { + const reportedStatus = goal.lastEvidence?.[0]?.description; // assumes index 0 + const match = reportedStatus?.match(/^Model report: (\w+)$/); // parses the string + if (match && ['complete','blocked','impossible'].includes(match[1])) { + await updateGoal({ status: match[1], actor: 'model', + reason: goal.lastEvidence?.slice(1).map(e => e.description).join('; ') ?? '…' }); + } + } + ``` + +**It works on the happy path** (because `recordModelReport` always writes the marker at +`lastEvidence[0]` with `source:'model_report'`), but it is exactly the brittle coupling +predicted in Phase 1a: +- ❌ **Writer/reader coupled by a string format.** The status only survives the round-trip + while the literal `` `Model report: ${status}` `` template and the `/^Model report: (\w+)$/` + regex stay in sync. Any wording change silently breaks terminal detection — the goal would + then never complete via self-report. +- ❌ **`find`-anywhere vs read-`[0]` mismatch.** It locates the marker with `find()` (any + index) but then reads `lastEvidence[0].description`. Today the marker is always at 0, so + it's latent, but the two assumptions can drift apart. +- ⚠️ **`lastEvidence` is overloaded.** `incrementTurn` and `recordEvaluatorVerdict` also + overwrite `lastEvidence`, so the model-report marker is fragile shared state rather than a + dedicated field. (Step 5 runs before `incrementTurn` in the same call, so the immediate + path is safe, but the field is doing triple duty.) +- ⚠️ **Reason/evidence fidelity.** Branch 1 forwards the structured + `lastModelReportReason` / `lastModelReportEvidence`; Branch 3 reconstructs the reason by + `join('; ')`-ing the remaining evidence descriptions. + +### Other divergences +- ⚠️ **Terminal actor.** Branch 1 records the self-report terminal as `actor: 'continuation'`; + Branch 3 uses `actor: 'model'`. +- ⚠️ **Turn-increment ordering.** Branch 1 increments the turn *before* the model-report + check (the reporting step counts as a continuation turn); Branch 3 checks the report + *before* incrementing (the reporting step is not counted). Minor accounting difference. +- ✅ **Return contract — Branch 3 is arguably cleaner here.** Branch 3 returns + `ShouldContinueAfterStopResult | undefined`, using `undefined` for "goal mode not + applicable, defer to default turn behavior". Branch 1 returns `STOP` (`{continue:false}`) + when disabled, which is a firmer hand. Branch 3's "no opinion" signal is the nicer design. +- ⚠️ **Once-only wrap-up mechanism.** Branch 3 uses explicit `budgetWrapUpUsed` / + `maxStepsWrapUpUsed` boolean latches; Branch 1 relies on `markBudgetLimited` flipping the + goal terminal so the next step stops at the status guard. Both run the wrap-up exactly once. +- ❌ **`finalizeWallClock` is fire-and-forget on Branch 3** (`void recordWallClockUsage(...)`, + and it's a sync method) and it *skips* the final interval if the goal is no longer active; + Branch 1 `await`s it and records regardless of terminal state. Same fire-and-forget theme + as Phase 4b. +- ✅ Continuation + budget-wrap-up prompts are semantically equivalent; Branch 3 additionally + re-states the `Objective:` inline in both prompts (consistent with its no-`` + injection style). + +### Net assessment (Phase 4c) +Functionally the two controllers should behave the same on normal runs, **including +self-report termination** — Branch 3 did make the model's `complete/blocked/impossible` +report end the goal. But it pays for the Phase 1a type shortcut here: terminal detection now +hinges on a **string template matched by regex**, which is the single most fragile line in +the whole Branch 3 implementation. Recommend Branch 3 either restore a structured +`lastModelReportStatus` field or, at minimum, centralize the marker format as a shared +constant used by both writer and reader. The fire-and-forget `finalizeWallClock` is a +secondary concern. + +--- + +## Phase 4d — independent `GoalEvaluator`, integrated into continuation (`ceafdd5`) + +Both branches add an LLM-based `agent/goal/evaluator.ts` and rewire the continuation loop so +that **goal completion is evaluator-driven**. Strong architectural convergence here. + +### ⭐ Important: this largely *moots* the Phase 4c fragility finding +Phase 4c flagged Branch 3's regex parse of the model-report string as "the single most +fragile line." **Phase 4d removes that block entirely** (on both branches): +- **Branch 1** deletes its `lastModelReportStatus` "Level-1 terminal decision" and instead + passes the report to the evaluator as advisory `modelReport` evidence; the **evaluator's + verdict** is now the terminal trigger. +- **Branch 3** deletes the regex-parse terminal block and replaces it with + `extractModelReport()` → fed to the evaluator as an advisory string. + +So the model-report status is **no longer load-bearing** on either branch. Branch 3's +string extraction still exists (`extractModelReport` finds `source:'model_report'` and joins +descriptions), but if it ever broke, the evaluator would simply lose a hint and still judge +from conversation context. **Net: the 4c risk drops from "could prevent goal completion" to +"could lose an advisory hint."** A good example of why watching consecutive commits matters — +the 4c snapshot looked dangerous in isolation; 4d resolved it. + +### What matches Branch 1 ✅ +- Independent evaluator over the main agent's `llm`, strict-JSON output. +- **Identical verdict taxonomy:** `continue | complete | blocked | impossible | no_progress`. +- Completion is **evaluator-driven**; the model self-report is advisory only. +- Evaluator tokens are charged to the goal budget with `source: 'goal_evaluator'`. +- Terminal verdicts (`complete/blocked/impossible`) → `updateGoal(actor:'evaluator')` → stop. +- `no_progress` honored against `noProgressTurnLimit`; evaluator failures tracked against + `failureTurnLimit` → `markError`. Budgets re-checked after the (token-spending) evaluator call. + +### Divergences / findings +- ⚠️ **Evaluator testability seam.** Branch 1 injects a `createEvaluator` factory + + `GoalEvaluatorLike` interface so tests (and future variants) can swap the judge. Branch 3 + hard-codes `new GoalEvaluator(ctx.llm)` inside the controller — no seam, harder to unit-test + the loop without a live LLM. +- ⚠️ **Error modeling.** Branch 1 keeps evaluator failure separate (`recordEvaluatorFailure` + + an ok/error result union). Branch 3 folds it into the verdict union as a pseudo-verdict + `'error'` (`GoalEvaluatorVerdict | 'error'`) routed through `recordEvaluatorVerdict`. + Branch 3's is more compact but overloads the verdict field. +- ⚠️ **Evaluator token sum.** Branch 1 uses `grandTotal(result.usage)`; Branch 3 hand-sums + `inputOther + output + inputCacheRead + inputCacheCreation`. If `grandTotal` covers any + other component, Branch 3 will under/over-count evaluator tokens versus the rest of its + accounting (which *does* use `grandTotal` in Phase 4b). Worth reconciling to one helper. +- ❌ **Budget re-check ordered *before* the terminal verdict on Branch 3.** In Branch 3 the + post-evaluator code runs the budget re-check (step "8") and `markBudgetLimited` **before** + it applies a `complete/blocked/impossible` verdict (step "7" — note the stale, out-of-order + comment numbers). Consequence: if the evaluator returns `complete` *and* its own token cost + tipped the goal over budget, the goal is marked **`budget_limited` instead of `complete`**. + A genuinely-finished goal can be mislabeled. Recommend applying the terminal verdict before + the budget re-check. (Branch 1 records the verdict and checks the terminal verdict in a + flow that doesn't appear to subordinate completion to the post-eval budget check — worth a + side-by-side confirm, but Branch 3's ordering is the riskier of the two.) +- ❌ **`noProgressTurnLimit` / `failureTurnLimit` are effectively unreachable on Branch 3.** + This is the concrete payoff of the Phase 2/3 gaps: those two limits can't be set from + `/goal create` (Phase 2) or the `CreateGoal` tool schema (Phase 3) — only via the raw SDK. + So Branch 3's `no_progress`-limit and evaluator-failure-limit stop conditions exist in code + but **almost never fire** in practice, because the limits default to `undefined`. Branch 1 + exposes all five budget fields in the `CreateGoal` schema, so these stops are reachable. +- ⚠️ Evidence shape in the evaluator prompt differs (`{description,source?}` vs `{summary}`), + consistent with the long-standing evidence-shape divergence. +- ✅ Branch 3 added the `consecutiveNoProgressTurns` / `consecutiveFailureTurns` counting to + `recordEvaluatorVerdict` in this phase (it was absent in its 1a version), so the counters + the limits rely on are now maintained. + +### Net assessment (Phase 4d) +The core decision — **an independent evaluator owns completion, the model only reports** — is +implemented the same on both branches, and it retroactively neutralizes the 4c fragility. +The remaining Branch 3 concerns are (1) the **terminal-verdict-vs-budget ordering**, which can +mislabel a completed goal as budget-limited, and (2) the **unreachable no-progress/failure +limits** stemming from the earlier surface gaps. The missing test seam and the bespoke token +sum are lower-severity polish items. + +--- + +## Phase 5 — end-to-end integration + gates (`8265869`) + +Both branches add an end-to-end harness test `test/harness/goal-session.test.ts` (Branch 1 +214 lines, Branch 3 193). Beyond that the two Phase 5 commits have **different character**: +- **Branch 1** is a clean integration commit: harness test + **flag/env-var docs** + (`docs/en/configuration/env-vars.md`, +15) + a one-line turn fix + a dispatch test tweak. +- **Branch 3** bundles the harness test with a **lint-cleanup sweep across the goal modules** + (removing now-unused `ErrorCodes`/type imports, `_`-prefixing unused params, type + narrowing). This implies earlier Branch 3 phases were committed carrying lint debt that's + only being paid down now; Branch 1 kept each phase clean. + +### ✅ Two more self-corrections on Branch 3 +The Phase 5 cleanup quietly fixes two issues, one of which I flagged earlier: +- ✅ **`await this.agent.goals?.recordTokenUsage(...)`** in `turn/index.ts` afterStep — the + missing `await` I flagged in **Phase 4b** is now added, closing the read-modify-write race + on `tokensUsed`. +- ✅ **`await this.markGoalOnCancel()`** — another missing-await fixed on the cancel path. +- ⚠️ Also narrows `error.details?.['maxSteps'] !== undefined` → `typeof … === 'number'` + (more robust maxSteps detection). + +### Findings / remaining gaps +- ❌ **No user-facing flag/env-var docs on Branch 3.** Branch 1's Phase 5 documents the goal + feature flag / env vars in `docs/en/configuration/env-vars.md`; Branch 3 ships none. A + documentation gap for shipping the feature. +- ❌ **The two Phase 4d bugs are still unaddressed** — the terminal-verdict-vs-budget + ordering (completed goal can be mislabeled `budget_limited`) and the unreachable + `noProgressTurnLimit`/`failureTurnLimit`. Phase 5's sweep was lint-only and didn't touch + these. +- ⚠️ **`clearGoalInternal(_actor, _reason)`** — Branch 3 now formally ignores the actor and + reason on clear (params `_`-prefixed), confirming the lighter clear-audit attribution noted + back in Phase 1b. Branch 1 threads actor/reason through clear. +- ⚠️ `UpdateGoal` input `status` type narrowed from `GoalStatus` to the literal + `'complete' | 'blocked' | 'impossible'` — a small correctness tightening unique to Branch 3. + +### Net assessment (Phase 5) +Both reach an end-to-end-tested state. Branch 3 continues its pattern of **fixing its own +earlier rough edges** (two missing awaits closed here), which is reassuring. The notable +deltas vs Branch 1 are process/polish: Branch 3 carried lint debt into a late catch-up +commit and **still lacks the feature-flag documentation** Branch 1 shipped. The substantive +4d behavioral bugs remain open going into Phase 6. + +--- + +## Phase 6 — headless goal mode + hardening (`b22fc19`) + +Both add headless `/goal` execution with a terminal-status → exit-code mapping and a printed +summary. Branch 1 puts it in a dedicated `cli/goal-prompt.ts`; Branch 3 puts +`resolveGoalExitCode` in `cli/run-prompt.ts` and extracts shared parsing into a new +`apps/kimi-code/src/utils/goal.ts`. Branch 3's phase also adds **SDK events**, which +Branch 1 does not have. + +### ✅ Branch 3 capabilities Branch 1 lacks +- ✅ **SDK goal lifecycle events.** Branch 3 emits `goal.created`, `goal.updated` + (with `previousStatus`), `goal.evaluated`, `goal.continued`, `goal.cleared` over the SDK + event stream (store gets an injected `emitEvent`; the continuation controller emits + `goal.continued`). Branch 1 has only the internal audit *records* from Phase 1b — no + real-time SDK event surface. This is a genuine observability win for Branch 3. +- ✅ **The Phase 2 budget-flag gap is fixed here.** The new `utils/goal.ts` parses + `--max-tokens` / `--max-turns` / `--max-minutes` (→ `tokenBudget` / `turnBudget` / + `wallClockBudgetMs`), shared by both the `/goal` slash command and headless mode. The + `tui/commands/goal.ts` shrank by ~92 lines as it adopted the shared parser. Good + deduplication and a real fix to the earlier gap. + +### ❌ Findings +- ❌ **Headless exit-code contracts are incompatible — and Branch 3 conflates failure with + success.** Only `complete = 0` agrees. Otherwise: + + | status | Branch 1 | Branch 3 | + |---|---|---| + | complete | 0 | 0 | + | error | **1** | **0** (default) | + | blocked | 3 | 10 | + | impossible | 4 | 11 | + | budget_limited | 5 | 12 | + | interrupted | 6 | **0** (default) | + | cancelled | 7 | 130 | + + The values simply differ (fine on its own), but **Branch 3 maps `error` and `interrupted` + to `0`**, so a script can't distinguish an errored or interrupted goal from a completed + one. Branch 1 gives every non-complete terminal state a distinct non-zero code. This is a + real headless-usability regression on Branch 3. +- ❌ **`noProgressTurnLimit` / `failureTurnLimit` are *still* unreachable.** The new + `utils/goal.ts` parser handles only the three basic budgets — it does not parse the + no-progress / failure limits, and the `CreateGoal` tool schema still omits them (Phase 3). + So the Phase 4d no-progress and evaluator-failure stop conditions remain effectively + dormant for all non-SDK callers. This is now the longest-standing open gap. +- ❌ **The Phase 4d terminal-verdict-vs-budget ordering bug remains** (completed goal can be + mislabeled `budget_limited`). Not touched in Phase 6. +- ⚠️ Branch 3's `goal.ts` adds a `GoalEventEmitter` typed as + `(event: { type: string; [k:string]: unknown }) => void` — loosely typed (untyped payload), + whereas the `rpc/events.ts` event interfaces are precise; the store-side emit isn't checked + against them. + +### Net assessment (Phase 6) +Branch 3 ends strong on *features* — it ships **SDK lifecycle events Branch 1 never added** +and finally closes the budget-flag parsing gap. But its **headless exit-code contract is +weaker** (error/interrupted indistinguishable from success), and the two structural problems +carried from Phase 4d (verdict/budget ordering; unreachable no-progress/failure limits) +survive to the end. + +--- + +## Overall verdict (Phases 1a–6 complete on both branches) + +Branch 3 reached **full phase parity** with Branch 1. It is a *hybrid* design: it took +Branch 2's cleaner type layout (wrapper `GoalSnapshot`, `string` actors, no dedicated +`lastModelReport*` fields) but restored Branch 1's safer **awaited, single-source-of-truth +persistence**. The two implementations are **behaviorally equivalent on the core happy path** +— create → inject → autonomous continuation → evaluator-driven completion — and they made the +same load-bearing decisions (audit-only records, replay-ignore, resume→paused normalization, +model-reports-are-advisory, evaluator owns completion). + +**Where Branch 3 is genuinely better than Branch 1:** +- Smarter injection cadence (full/sparse/refresh dedup) vs Branch 1's always-full re-inject — + more relevant to keeping the goal alive over long runs. +- SDK goal lifecycle events (Branch 1 has none). +- Cleaner continuation return contract (`undefined` = defer vs Branch 1's blanket `STOP`). +- A visible pattern of **self-correcting its own earlier issues** (paused-accrual in 4b, + missing awaits in 5, budget-flag parsing in 6). + +**Open issues on Branch 3, by severity:** +1. ❌ **4d ordering bug** — a `complete` verdict can be overridden to `budget_limited` when the + evaluator's own tokens cross the budget. Mislabels finished goals. *Highest priority.* +2. ❌ **`noProgressTurnLimit` / `failureTurnLimit` unreachable** outside the raw SDK — the + evaluator's no-progress / failure stops rarely fire. +3. ❌ **Headless exit codes conflate `error`/`interrupted` with success (`0`).** +4. ⚠️ **No `` prompt-injection framing** in context injection (Branch 1 + hardens this; security regression). +5. ⚠️ **Fragile model-report string coupling** — mostly mooted by 4d (advisory only) but still + present via `extractModelReport`. +6. ⚠️ Weakest goal-ID scheme (`goal-${Date.now()}`, same-ms collision); missing flag/env-var + docs; thinner type-safety (no `GoalActor`, non-`.strict()` schemas, third distinct + `GoalEvidence` shape); no evaluator test seam; bespoke evaluator token sum vs `grandTotal`. + +**Bottom line:** Branch 3 is a credible, broadly-consistent reimplementation that even +surpasses Branch 1 on a few axes (injection cadence, SDK events). It is *not* a drop-in match +— the public types (snapshot shape, evidence shape, exit codes, event surface) differ enough +that consumers are not interchangeable. Before it could be considered on par with the +finished Branch 1, the items worth fixing are, in order: the **4d verdict/budget ordering**, +the **unreachable no-progress/failure limits**, the **headless exit-code conflation**, and +restoring the **`` hardening**. + diff --git a/plan/phase-07-goal-ux-and-budget.md b/plan/phase-07-goal-ux-and-budget.md new file mode 100644 index 00000000..6a63486d --- /dev/null +++ b/plan/phase-07-goal-ux-and-budget.md @@ -0,0 +1,148 @@ +# Phase 7: Goal UX and Budget Model + +## Goal + +Make goal mode visible and controllable in the TUI, and replace the surprising +default turn cap with a counters-plus-evaluator model.
