Summary

  • The Integrations > Cursor card predicted the Reasoning ladder from a hand-copied mirror of Cursor Private Inference's built-in effort table. This reads the table from the detected install instead (extensions/cursor-agent-exec/dist/main.js), so the prediction follows a Cursor update; the static 3.18.25 mirror stays as the fallback when no install is found or the literal cannot be parsed.
  • New src/integrations/cursor-effort-table.ts: bounded, read-only parse of the minified family table (regex, ladder, default, outputCap, bare gpt-5 rule), cached by path+mtime+size. predictCursorEffort in models-capabilities.ts resolves ladder + source + family. The status route adds effortTable: { source, version, families } and a per-row family; the dashboard API client type in cursor-api.ts mirrors the two fields; no visual change in this PR (rendering lands in a follow-up).
  • Roadmap and evidence: devlog/_plan/260902_cursor_bundle_effort_table/010 (docs(devlog): Cursor bundle effort-table roadmap (wp0) #3272).

Verification

  • bun run typecheck → exit 0
  • bun test tests/cursor-effort-table.test.ts tests/cursor-integration-status.test.ts tests/core-lab-boundary.test.ts tests/cursor-local-models-schema.test.ts → 38 pass / 0 fail
  • Live against the installed build: effortTable {"source":"bundle","version":"3.18.25","families":16}; anthropic/claude-opus-5 → low/medium/high/xhigh/max [anthropic-opus-5], cursor/grok-4.6 → minimal…xhigh [grok-4.6], anthropic/claude-fable-5-1 → null (Cursor 3.18.25 has no fable family)
  • Fallback activation is a test case (missing install, missing literal, malformed regex → static mirror)

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

  • New Features

    • Cursor integration status now identifies effort-control families and whether settings come from the installed Cursor bundle or a fallback mirror.
    • Effort settings adapt to the installed Cursor version when bundle data is available.
    • Models without reasoning support no longer show unsupported effort controls.
    • Added fallback behavior when Cursor bundle data is unavailable or invalid.
  • Documentation

    • Added guidance covering Cursor effort controls, model capabilities, configuration, and verification.

Merge Risk: 🔵 Low · up to 25ff6

The PR updates Cursor effort prediction to read a bounded local bundle with a static fallback and adds provenance to integration status, so impact is limited mainly to displayed status data. It is mergeable with owner awareness for model-ID matching, the bundle size-check race, and completion of the required validation commands.

이 PR은 방금 dev에 들어온 #3272 로드맵의 wp1 구현입니다. Integrations > Cursor 카드가 Reasoning 사다리를 손복사 미러(src/server/models-capabilities.tsCURSOR_EFFORT_FAMILIES)로만 예측하던 것을, 탐지된 Cursor Private Inference 설치의 extensions/cursor-agent-exec/dist/main.js에서 family 테이블을 읽어 따라가게 합니다. 지금 체크아웃한 dev HEAD는 345e2175c (docs(devlog): Cursor bundle effort-table roadmap (#3272))이고, 그 tip에는 이미 devlog/_plan/260902_cursor_bundle_effort_table/ 전체가 있습니다. Private Inference 스택(#3230+#3231+#3247+#3248+#3249)과 cursor-detect / status 라우트 / GUI 타입은 그대로인 상태에서, 이 PR이 비는 구멍은 “번들 테이블을 실제로 읽는 코드”입니다.

새 파일 src/integrations/cursor-effort-table.ts는 읽기 전용·32 MiB 상한·(path, mtime, size) 캐시·파싱 실패 시 null로 정적 폴백을 타게 설계되어 있습니다. predictCursorEffort가 ladder·source·family를 돌려주고, status 라우트는 effortTable: { source, version, families }와 행별 family를 노출합니다. GUI는 타입만 맞추고 렌더는 wp4 후속으로 미룹니다. 테스트는 fixture 파싱·예측·폴백·캐시·status 주입까지 38개로 잡혀 있고, 본문 검증(typecheck + 관련 bun test + 실기 3.18.25 프로브)도 로드맵 010과 맞습니다. types.ts/config.ts 대분할과 무관하고, 중복 close 대상도 아닙니다.

다만 브랜치에 이미 머지된 #3272와 같은 docs 커밋(063671ce3)이 아직 들어 있습니다. tip은 345e2175c인데 PR 쪽은 그 merge commit의 조상이 아니라서, 그대로 머지하면 plan 파일이 다시 한 번 올라오거나 리베이스가 필요합니다. draft 상태이므로 Ready 전에 dev 위로 docs 커밋을 빼고 feat만 올리는 게 맞습니다. CI에는 FAILURE 한 칸이 보이니, 리베이스 후 체크도 다시 초록인지 확인해야 합니다.

라인 58 - src/integrations/cursor-effort-table.tsindexOf('=[{id:"anthropic-') 앵커는 첫 family id가 항상 anthropic-로 시작한다고 가정합니다. Cursor가 테이블 순서를 바꾸면 전체 파싱이 null로 떨어져 정적 폴백만 씁니다. 동작은 안전하지만, 실패 이유를 status/로그에 한 줄 남기면 운영이 편합니다.

라인 86 - 같은 파일의 bare gpt-5 규칙은 미니파이 변수명 t를 하드코딩합니다(if(/.../.test(t))). 식별자가 바뀌면 bareGpt5만 null이 되고 family 배열은 살아 남습니다.

라인 73-87 - src/server/models-capabilities.ts predictCursorEffort는 테이블이 non-null이면 unmatched·bare 실패도 source: "bundle" + ladder: null로 끝납니다. bare 규칙만 파싱 실패했을 때 gpt-5.*가 정적 미러로 안 떨어지고 null이 됩니다. “부분 파싱 성공 = 번들 권위” 정책인지, bare 실패 시 정적 폴백을 섞을지 정해야 합니다.

경로 gui/.../cursor-api.ts - effortTable·family 타입만 추가되고 카드 UI는 안 그립니다. wp4 범위라 의도된 분리지만, Ready 전에 “타입만 / 렌더 후속”을 본문에 한 줄 더 박아 두면 리뷰어 혼선이 줄어듭니다.

경로 PR 커밋 063671ce3 vs dev #3272 - plan 문서 내용이 tip과 동일합니다. 리베이스로 docs 커밋을 drop하고 8af13df33 feat만 남기세요. 문서 재추가는 필요 없습니다.

경로 draft / CI - draft 유지·체크 일부 FAILURE 상태에서는 랜딩 후보가 아닙니다. 리베이스 후 typecheck·관련 테스트·enforce 계열이 초록인지 확인하세요.

메인테이너의 판단이 필요한 지점

  • bare gpt-5 규칙 파싱 실패 시: 전체 null(지금과 같이 정적 폴백) vs family만 살리고 bare만 정적으로 섞기
  • 번들 source인데 모델 unmatched일 때 null을 “Cursor에 컨트롤 없음”으로 확정할지, 정적 미러에만 있는 선반영 엔트리(예: 앞으로 넣을 fable)를 섞을지
  • wp1만 Ready로 올리고 wp2(max_output)·wp4(GUI 힌트)는 별 PR로 갈지 (로드맵·이 PR 범위는 이미 그렇게 잡혀 있음)
  • Windows/Linux 번들 리터럴이 darwin fixture와 다를 때 011 기록 + 정적 폴백만 쓸지 (010 escalation과 동일)

너의 추천
방향은 맞고 우선 머지 후보입니다. 지금은 draft를 유지한 채 (1) origin/dev(345e2175c) 위로 리베이스하며 docs 커밋을 제거하고, (2) 관련 테스트·CI를 다시 초록으로 맞춘 뒤, (3) bare gpt-5 하드코딩/anthropic- 앵커 실패 시 관측 가능성만 짧게 보강한 다음 Ready로 전환하세요. 코드 품질·폴백·주입 테스트는 이미 랜딩 수준입니다. types/config 분할·중복 close 대상이 아닙니다.

P2 Badge Reject partially parsed effort tables

When a Cursor update adds an unrecognized property to only one family row, this strict entryRe silently skips that row while the later families.length !== 0 check accepts the rest of the table. The status route then reports source: "bundle", and models belonging to the skipped family receive reasoning: null instead of using the static fallback; for example, inserting newFlag:!0 into the first fixture row yields a 15-family table with anthropic-opus-5 missing. Validate that the complete table window was consumed, or reject any unparsed family row so the optional integration degrades to the static table.

Fixed in 965b300: the parser now counts {id:" openers in the table window and returns null unless every one was consumed, so a build that adds a property to one family falls back to the static mirror. Regression case added (newFlag:!0 on the first row → null).

P2 Badge Catch failures when compiling the bare GPT regex

If an installed bundle is corrupt or being replaced and the extracted bare-GPT pattern is malformed while the family table remains parseable, this new RegExp throws because it is outside the guarded family-pattern compilation. That exception escapes loadCursorEffortTable and turns GET /api/native-integrations/cursor into a 500 instead of selecting the documented static fallback. Compile this pattern under the same error handling and return null for the whole parse on failure.

P2 Badge Document the installed-bundle prediction source

This changes the dashboard's Reasoning predictions from a fixed mirror to data read from the user's installed Cursor version, with a static fallback, but docs-site/src/content/docs/guides/cursor-private-inference.md:99-117 still presents one unconditional effort matrix and does not explain bundle provenance or fallback behavior. After a Cursor update changes the table, the documented ladder can therefore contradict the dashboard; update the guide to describe the installed-bundle source and qualify the existing matrix as the fallback snapshot.

Tracked: the guide update is the last phase of this stack (devlog 060_wp6_guide.md) and will qualify the matrix as the 3.18.25 fallback snapshot and describe the installed-bundle source.

No GUI change in this PR: gui/src/pages/integrations/cursor-api.ts only gains two TypeScript fields on the API client type; nothing renders differently. The dashboard rendering ships separately with a screenshot.

In
`@devlog/_plan/260902_cursor_bundle_effort_table/030_wp3_effort_variant_rows.md`:
- Around line 106-113: The parseEffortRowId flow must resolve exact known IDs
before interpreting the synthetic effort-row suffix. Update the surrounding
lookup logic to check static, live, custom, combo, policy, and alias identifiers
first, returning the exact match unchanged; only apply the separator and
declared-effort parsing when no exact ID exists.
- Around line 115-117: Update the table-less decision paths, including the logic
around cursorEffortFamily and the additional row-expansion, request-parsing, and
management-status sites, to resolve and reuse the installed effort table via the
shared helper. Ensure predictCursorEffort(...).ladder is used when available,
with cursorEffortFamily only as the fallback, so all decisions consistently
reflect the installed bundle.
- Around line 129-135: Update the routed-row variant generation to provide a
non-empty Cursor Fable ladder for claude-fable-5-1, preferably through the
appropriate capability data. In the guard near canonicalizeReasoningEfforts, use
predictCursorEffort(...).ladder from the installed table first, falling back to
cursorEffortFamily(row.id) only when no prediction exists, so table-less Kimi
and Qwen rows retain their configured variants.

In
`@devlog/_plan/260902_cursor_bundle_effort_table/040_wp4_gui_provenance_hint.md`:
- Around line 24-25: Complete the Cursor status contract by adding tableLess and
effortRows to CursorModelExpectation and the corresponding client type, emit
both fields from the management route, and assert their values in
tests/cursor-integration-status.test.ts. Keep the GUI state aligned with the
management API response so the page can safely consume these fields and support
table-less guidance.
- Line 38: Move the visible fallback placeholders from CursorIntegrationPage
into localization: add locale keys for the unknown version placeholder and em
dash, then replace the inline "?" and "—" values with t(...) lookups while
preserving the existing integration labels and fallback behavior.
- Line 45: The non-focusable no-control marker span needs an accessible
description that does not depend on the title tooltip. Update the marker near
the cursor control rendering to use localized descriptive text via
aria-describedby, visually hidden text, or visible cell text, while preserving
the existing dash and localization key.
- Around line 9-10: Add bun run lint:i18n and bun run build to the verifier and
acceptance criteria alongside the existing GUI checks, ensuring the documented
validation covers UI translation changes and the full build.
- Line 69: Update the integrations.cursor.effortRowsOn localization message to
use the existing pluralization mechanism or distinct singular/plural keys, so
zero and multiple counts render “effort rows” while a count of one renders
“effort row”; add or update coverage for zero, one, and multiple rows.

In `@src/integrations/cursor-effort-table.ts`:
- Line 89: Update loadCursorEffortTable so constructing the bare GPT-5 RegExp
from bareRe[1] is covered by the existing parse-failure handling; invalid
patterns must return null rather than throw, allowing the static fallback to
run. Add a fixture covering an invalid bareRe pattern and assert loading returns
null without throwing.
- Line 122: Update loadCursorEffortTable to open the bundle once, validate its
size with fstat on that descriptor, and read from the same descriptor so path
replacement cannot bypass the 32 MiB limit; ensure the descriptor is closed on
every success and error path, and add coverage for replacement between
validation and reading.
- Line 63: Update parseCursorEffortTable to verify that entryRe consumes every
table entry, not only whether families is non-empty; return null when any
valid-looking entry contains an unrecognized property so predictCursorEffort
uses the static fallback. Add a regression fixture covering an otherwise valid
entry with an extra property.

In `@src/server/models-capabilities.ts`:
- Around line 73-89: Update predictCursorEffort to accept the matched capability
row and endpoint-wide extendedCapabilitiesDetected state, then honor
requiresReasoningCapability before returning a ladder for both bundle and static
prediction paths. Preserve unsupported results when Gemini or legacy rows fail
their capability gates, and add regression coverage for supported and
unsupported Gemini cases.

In `@tests/cursor-effort-table.test.ts`:
- Around line 91-102: Expand the cache invalidation test around
loadCursorEffortTable to cover each cache-key component: keep mtimeMs unchanged
while changing size and assert readText runs again, then use a distinct INSTALL
path and assert another read. Preserve the existing assertions for the initial
cache hit and modification-time change.
- Line 70: Extend the test covering missing cursor-effort data to call
loadCursorEffortTable with an undefined install and missingStat, and assert that
it returns null. Keep the existing missing-bundle-file assertion intact so both
fallback branches remain covered.

Resolve exact model IDs before parsing synthetic rows.

The plan states that exact known IDs take precedence, but parseEffortRowId accepts any terminal --<declared-effort> suffix before performing an exact-ID lookup. Because -- is not globally forbidden, a real model such as <known-id>--high would be rewritten to <known-id> and receive injected effort metadata. Resolve static, live, custom, combo, policy, and alias IDs before applying the synthetic grammar.

Use the installed effort table for every table-less decision.

Lines 15-18 require predictCursorEffort(...).ladder with cursorEffortFamily as the fallback. These sites call cursorEffortFamily directly. A changed installed bundle can therefore make row expansion, request parsing, and management status disagree with the bundle. Thread the resolved WP1 result through a shared table-less helper.

Also applies to: 124-126, 324-334

Provide a ladder for Fable rows and use the installed Cursor table.

  • The routed-row call at devlog/_plan/260902_cursor_bundle_effort_table/030_wp3_effort_variant_rows.md:167 passes m.reasoningEfforts. The Anthropic registry registers claude-fable-5-1 without reasoningEfforts or modelReasoningEfforts (src/providers/registry.ts:1313-1315). Therefore, lines 129-135 receive an undefined ladder and emit no Fable variants. Add a dedicated Cursor Fable ladder or declare the model ladder in the appropriate capability data.
  • Kimi and Qwen have non-empty configured ladders. However, line 125 still uses cursorEffortFamily(row.id) instead of WP1's bundle-first predictCursorEffort(...).ladder. This treats cursor/kimi-k3 as table-matched and suppresses its variants even though WP1 classifies it as table-less. Use the installed-table prediction for this guard and retain the static family only as its fallback.

Exercise the missing-install branch.

This test passes INSTALL, so stat: () => null verifies a missing bundle file, not a missing install. Add loadCursorEffortTable(undefined, missingStat) and assert null; otherwise the missing-install fallback can regress without failing the suite.

As per path instructions, tests under tests/** must add focused regression coverage for behavior changes in src/**.

Test every cache-key component.

The test name claims coverage for bundle path, modification time, and size, but only mtimeMs changes. Keep the modification time constant while changing size, then use a second install path and assert that readText runs again for both cases.
