Summary

  • Adds an experimental Devin/Cognition/Windsurf adapter using the unofficial cloud-direct Connect-RPC transport (GetChatMessage), with live model discovery via GetCascadeModelConfigs.
  • ocx login devin imports ~/.pi/agent/auth.json by default, with a Windsurf browser sign-in fallback.
  • The adapter is runTurn-only (like Cursor): buildRequest/parseStream are disabled with an error, and all streaming flows through runTurn -> streamChatEvents.
  • Fixes two issues found during end-to-end verification:
    • Terminal done/usage: the adapter forwarded text, reasoning, and tool events but never emitted the internal terminal done event or usage, leaving Claude Code and Codex hanging on stream completion. Now captures usage/stopReason, maps "length" to "max_tokens", and emits done after the stream unless aborted.
    • Cognition content filter: Claude Code's built-in TaskOutput tool description contains the exact 7-word phrase "Takes a task_id parameter identifying the task", which triggers a Cognition server-side exact-phrase blocklist and returns permission_denied regardless of model or account tier. Binary-search verified the trigger is case-sensitive, whitespace-exact, and substring-matched. The cloud-direct encodeToolDef layer rewrites the known phrase to a meaning-preserving form ("Accepts ..."), alongside the existing 6998-char length truncation.
  • Updates stale adapter-registry-authority and adapter-tool-conformance tests for the new Devin registry entry (runTurn-only adapter, skipped from wire-path conformance).

Verification

  • bun test tests/devin-adapter.test.ts -- 5 pass (registration, message/tool mapping, model filtering, token import, blocklist rewrite)
  • bun test tests/adapter-registry-authority.test.ts -- 6 pass
  • bun test tests/adapter-tool-conformance.test.ts -- 5 pass
  • bun run privacy:scan -- passed
  • bun x tsc --noEmit -- no new errors (2 pre-existing timeout/RequestInit errors on upstream/dev in fetch-helpers.ts/claude-messages.ts)
  • Live cloud-direct test: streamChatEvents with swe-1-7 returned PONG with end_turn and usage
  • Proxy /v1/messages test: unsanitized trigger phrase -> permission_denied; sanitized -> PONG with usage
  • Proxy /v1/responses test: tool calling returned tool_use block (get_weather, stop_reason: tool_use); compaction trigger returned exactly one compaction output item with ocx1:-prefixed summary
  • ocx claude end-to-end: Claude Code v2.1.266 with swe-1-7 (devin) -- PONG received; Read tool used successfully (AGENTS.md); /compact completed successfully

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed. -- Follow-up: Devin is not yet documented in docs-site/ (adapters reference, providers guide). Pre-existing gap from the initial adapter commit; will address in a separate docs PR.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. -- OAuth token import reads ~/.pi/agent/auth.json (local file, no logging); no secrets exposed; content-filter rewrite is meaning-preserving.

Import an existing Pi Devin API key, expose ocx login devin, and route
GetChatMessage plus live GetCascadeModelConfigs discovery through a new
runTurn adapter.
… phrase

The Devin adapter forwarded text, reasoning, and tool events but never
emitted the internal terminal `done` event or usage, leaving Claude Code
and Codex hanging on stream completion. Add usage/stopReason capture,
map Devin's "length" finish to "max_tokens", and emit `done` after the
stream unless aborted.

Claude Code's built-in TaskOutput tool description contains the exact
7-word phrase "Takes a task_id parameter identifying the task", which
triggers a Cognition server-side exact-phrase blocklist and returns
permission_denied regardless of model or account tier. Binary-search
verified the trigger is case-sensitive, whitespace-exact, and
substring-matched. Rewrite the known phrase to a meaning-preserving
form ("Accepts …") in the cloud-direct encodeToolDef layer, alongside
the existing 6998-char length truncation.

Update stale adapter-registry-authority and adapter-tool-conformance
tests for the new Devin registry entry (runTurn-only adapter, skipped
from wire-path conformance).

설명

이 PR은 Cognition/Windsurf(Devin)용 실험적 비공식 cloud-direct 어댑터를 넣는다. 작성자 wtfsayo, 브랜치 feat/devin-adapter, base는 dev(맞음). 현재 로컬 dev HEAD는 8026405d9(#4067 wp7 proxy-stop refusal reason, package 2.49.0)이고 이번 웨이크에서 SHA는 변하지 않았다. 변경 규모는 약 +2793/−7, 파일 23개. 핵심은 (1) src/adapters/devin.ts runTurn-only 어댑터(Cursor처럼 buildRequest/parseStream은 막고 streamChatEvents로만 스트림), (2) src/adapters/devin/cloud-direct/* Connect-RPC protobuf 수동 인코딩(GetUserJwt / GetCascadeModelConfigs / GetChatMessage), (3) src/oauth/devin*~/.pi/agent/auth.json 로컬 임포트 우선 + Windsurf 브라우저 토큰 paste → RegisterUser, (4) PROVIDER_REGISTRY/ADAPTER_REGISTRY/OAUTH_PROVIDERS/provider-fetch 라이브 모델 필터, (5) Claude Code/Codex가 안 끝나던 문제를 고치려고 usage·stopReason·done 이벤트 방출, (6) Cognition 서버 문구 블록리스트(TaskOutput 설명의 exact phrase)를 description rewrite로 우회. 테스트는 tests/devin-adapter.test.ts + registry/conformance 갱신. 본문에 라이브 프록시·ocx claude e2e 통과 주장도 있다.

dev 대비 의미가 있나. OpenCodex는 Cursor·Kiro·Qoder처럼 비표준 업체 와이어를 자체 어댑터로 흡수하는 제품 방향이고, Devin/Windsurf 모델 레인(swe-1-7 등)을 피커에 올리면 사용자 선택지가 늘어난다. runTurn-only·라이브 카탈로그·terminal done/usage 수정·블록리스트 우회까지 한 번에 묶은 건 “반쯤 동작하는 스케치”가 아니라 e2e를 의식한 첫 슬라이스다. 다만 지금 dev tip은 2.49.x 백로그 마감(wp6 Bun, wp7 stopProxy 메시지, #3719/#3379/#3774/#3781/#3782 슬라이스 유지)이고 신규 벤더 OAuth 표면MAINTAINERS.md의 security review · maintainer-sponsored가 필요한 축이다. 게이트가 이미 unsponsored_surface로 hygiene fail + Draft + intake: hygiene-blocked를 걸었다. types.ts/config.ts 분할 무효화·중복 close 대상은 아니다.

라인 - 이게 무슨 문제다

게이트 unsponsored_surface - src/oauth/devin.ts, src/oauth/devin/login.ts, src/oauth/devin/register-user.ts, src/oauth/devin/types.ts, src/oauth/index.ts가 인증 표면이라 메인테이너 스폰서 라벨 없이는 Ready/머지 불가. enforce-target도 같은 이유로 fail. 기능 리뷰와 별개로 지금 상태는 Draft가 맞다.

src/providers/registry.ts Devin 엔트리 들여쓰기 - id: "devin" 앞에 공백이 과도하고, 바로 아래 기존 xai 블록의 id: "xai"는 들여쓰기가 사라져 {\nid: "xai", 형태가 됐다. 동작은 깨지지 않을 수 있어도 리뷰/포맷 회귀이고, 머지 전에 prettier/수동으로 정렬해야 한다.

src/server/request-log.ts contextWindowForModel - adapter === "devin"일 때 inferCursorContextWindow(modelId)를 부른다. Cursor discovery 휴리스틱이다. 이 PR의 Devin 레지스트리는 modelContextWindows에 swe-1-7=256k, gpt-5-6-*=1050k 등을 따로 넣었는데, 요청 로그 쪽은 Cursor 추정값을 쓰게 되어 usage/context 로그가 Devin 카탈로그와 어긋날 수 있다. Devin 전용 테이블(또는 registry modelContextWindows)을 읽게 바꿔야 한다.

src/adapters/devin/cloud-direct/chat.ts 파일 머리 주석 - “Tools … DOES NOT yet support”, docs/CLOUD_DIRECT.md, src/plugin.ts:planToolCall을 가리킨다. 같은 파일에 encodeToolDef·블록리스트 rewrite·도구 스트림이 있고, PR 본문은 tool_use/compaction e2e를 주장한다. 레포에도 docs/CLOUD_DIRECT.md는 없다(upstream pi-devin-auth에서 복사한 잔여로 보임). 주석/문서 경로가 코드와 모순이라 유지보수자가 “도구 미지원”으로 오해한다. 헤더를 현재 동작에 맞게 고치고 없는 doc 링크는 빼거나 opencodex 경로로 옮겨야 한다.

src/adapters/devin.ts cascadeIds Map - 어댑터 인스턴스 수명 동안 _clientThreadId/previousResponseId 키를 무한 적재한다. Cursor 쪽 continuity/store 패턴과 달리 eviction이 없다. 장기 프록시 프로세스에서 스레드가 많으면 메모리만 는다. TTL·max-size·thread end 시 delete 중 하나가 필요하다.

src/providers/registry.ts dashboardPreset: true + featured: false + note에 Experimental unofficial - 대시보드 프리셋에 실험적 비공식 브릿지가 올라가면 일반 사용자가 OAuth/ToS 위험을 모르고 켠다. 첫 랜딩은 dashboardPreset: false(또는 advanced-only)가 더 안전해 보인다. 제품 판단.

src/adapters/devin/cloud-direct/chat.ts Cognition blocklist rewrite - Claude Code TaskOutput의 exact 7단어만 테이블에 있다. Cognition이 문구를 바꾸거나 다른 built-in tool 문구를 추가하면 다시 permission_denied로 전 구간이 죽는다. 테스트는 rewrite 한 줄 잠금뿐이라, 실패 시 사용자에게 “content filter / tool description blocked”를 명시하는 에러 매핑과, 알려진 phrase 목록을 한곳에 모아 두는 주석/이슈 링크가 필요하다.

비공식 프로토콜 리스크 - server.codeium.com Connect-RPC, 고정 WINDSURF_VERSION_STRING = '2.0.0', 수동 protobuf, JWT mint 캐시. Cursor 어댑터와 같은 부류지만 Cognition ToS·계정 정지·스키마 드리프트는 메인테이너가 공개 제품에 실을지 결정해야 한다. “Generated with Devin” + 대량 vendor dump는 리뷰 부담도 크다(cloud-direct만 천 줄 넘게).

anySignal 폴리필 - cloud-direct/auth.ts, chat.ts(추정), oauth/devin/register-user.ts에 동일 구현이 중복된다. 공통 유틸로 빼지 않으면 Node 18 폴백 버그 픽스가 세 곳에 갈린다.

문서 - 작성자도 adapters reference / providers guide 미반영을 follow-up으로 인정. experimental이어도 ocx login devin·모델 목록·비공식 경고 한 페이지는 같은 열차에 있는 편이 사용자·리뷰어에게 낫다.

메인테이너의 판단이 필요한 지점

  • OAuth/인증 표면을 maintainer-sponsored로 받을지, 아니면 비공식 Cognition 브릿지라 닫거나 fork/experimental 플래그 뒤에만 둘지.
  • ToS·계정 위험 고지를 제품 UI/노트에 얼마나 강하게 넣을지(dashboardPreset 여부 포함).
  • 2.49.x 마감 열차와 직교하므로, 스폰서 후 독립 머지할지 / 다음 minor에 미룰지.
  • request-log context window를 Devin 테이블로 고치는 것을 머지 조건으로 둘지.
  • 문서 PR을 같은 랜딩에 필수화할지 follow-up으로 허용할지.

너의 추천

지금 당장 머지하지 말 것(Draft + hygiene-blocked가 맞음). 닫을 필요는 없다 — 방향·e2e·done/usage 수정은 가치가 있다. 작성자/메인테이너 다음 스텝: (1) registry 들여쓰기·xai id 복구, (2) request-log Devin context window를 Cursor 추정에서 분리, (3) chat.ts 머리 주석/없는 CLOUD_DIRECT.md 참조 정리, (4) cascadeIds eviction 또는 상한, (5) dashboardPreset 재검토, (6) 메인테이너가 OAuth 표면을 보안 리뷰한 뒤 maintainer-sponsored 부여, (7) 가능하면 providers/adapters 문서 최소 한 줄. 그다음 Ready + CI green 후 dev 독립 머지 후보. types/config 분할 무효화·중복 close 아님. 2.49 tip 슬라이스(#3719 등)와 파일 충돌은 거의 없어 보이지만, 스폰서 없는 인증 표면이라 우선순위는 중하위(49)로 둔다.

Live model discovery via GetCascadeModelConfigs returns effort-suffixed
variants (e.g. gpt-5-6-sol-medium), not bare base ids. The adapter was
sending bare ids that the cloud rejects. Now resolveWireModelUid appends
the reasoning effort (or "medium" default) for models that require a
suffix, and passes through no-suffix models (swe-1-7, glm-5-2, kimi-k2-7)
unchanged. Verified against the live catalog: all 11 static base models
resolve to UIDs the account can actually serve.

Also:
- Fix claude-fable-5 → claude-fable-5-1 (correct version in live catalog)
- filterDevinConfiguredModelsByLiveDiscovery now keeps a base model when
  its effort-suffixed variants appear in the live catalog, instead of
  dropping it
- Remove all "Pi CLI" / "Devin/Pi CLI" references from code and docs;
  the credential is described as "the local Devin credential" and the
  browser flow as "Auth0 browser sign-in"

Inline comments:
In `@src/adapters/devin/cloud-direct/auth.ts`:
- Around line 216-219: Update the inFlight handling in
src/adapters/devin/cloud-direct/auth.ts lines 216-219 and
src/adapters/devin/cloud-direct/catalog.ts lines 194-196: create shared promises
without callers’ signals, retain the internal timeout guards, and race each
caller’s await against that caller’s own signal. Add a regression test near the
existing Devin tests that aborts the first of two concurrent same-key requests
while in flight and verifies the second resolves.
- Around line 110-118: The auth flow must reject non-HTTPS API hosts before
credentials are assembled or any cached-host path runs. Add a shared
requireSecureHost resolver, invoke it in mintUserJwt before buildMetadata and
before cached-host reuse, allow only explicitly supported loopback exceptions,
and use the normalized host for auth, catalog, and chat requests.
- Around line 148-152: Remove the raw response body from CloudAuthError messages
in the authentication response handling. For the missing-JWT case, report only
the response size and parsed field numbers, never buf.toString output; for the
non-2xx response at the existing status-handling branch, use a fixed
status-and-length message. Ensure response.failed cannot receive upstream body
content.
- Around line 39-54: Extract anySignal into the shared signals.ts helper and
have it return both the combined AbortSignal and a cleanup function; retain the
native AbortSignal.any path and ensure fallback listeners are removed during
cleanup. Update the mintUserJwt and streamChatEvents flows in auth.ts and
chat.ts to invoke cleanup in finally after the combined signal is no longer
needed, while preserving cancellation throughout the full stream lifetime.

In `@src/adapters/devin/cloud-direct/catalog.ts`:
- Around line 197-208: Update getCachedCatalog and clearCachedCatalog to use the
existing auth.ts-style cacheEpoch invalidation pattern: increment the epoch when
clearing, capture the current epoch before awaiting fetchCatalog, and only
assign cached when the captured epoch still matches. Preserve the existing
inFlight cleanup and return behavior.
- Around line 126-135: Keep the request timeout and caller-abort forwarding
active through the response body reads in the catalog-fetch flow, rather than
clearing them immediately after fetch resolves. Move the cleanup currently in
the finally block surrounding fetch so it runs only after resp.text or
resp.arrayBuffer completes, while preserving HTTP error handling and cleanup on
fetch or body-read failure.

In `@src/adapters/devin/cloud-direct/chat.ts`:
- Around line 828-836: Update the catalog pre-flight in the chat request flow so
model validation runs only when catalog.byUid is non-empty; treat an empty
catalog as unavailable information and continue to the chat call. Preserve the
existing not_listed and disabled ModelNotAvailableError behavior for entries
found in a non-empty catalog, and keep fetchCatalog failures passed through as
before.
- Around line 1014-1022: Add an explicit maximum frame-length check in the
live-stream drain loop before waiting for or allocating the frame body,
rejecting or terminating processing when the server-supplied len exceeds the
configured/sensible Connect frame ceiling. Preserve normal handling for valid
frames and ensure an oversized prefix cannot leave chunkQueue growing
indefinitely; anchor the change to the loop reading len and the surrounding chat
stream parser.
- Around line 993-996: Update the idleController abort handler to cancel the
active stream through reader.cancel(...) rather than resp.body.cancel(...), and
handle the returned promise rejection to prevent an unhandled rejection.
Preserve the existing abort reason and settle rejection behavior.
- Around line 236-255: Update collapseSystemIntoUser to flush pendingSystem
before every non-system turn, including assistant and function_call_output/tool
messages, so synthesized system content precedes those messages; retain the
existing user-message wrapping behavior and trailing flush. Add a focused
regression test covering leading system, assistant, and tool messages to verify
the resulting order.

In `@src/adapters/devin/live-models.ts`:
- Line 74: Update the live-model mapping helper so it returns discovered model
IDs without casting incomplete `{ id }` objects to T. In
fetchProviderModelsWithAuth, construct complete CatalogModel rows for
discovered-only models using provider: name and
catalogHintsFromProviderConfig(...), preserving provider identity and metadata.

In `@src/codex/catalog/provider-fetch.ts`:
- Line 1679: Update the Devin discovery failure path around
markProviderDiscoveryFailed to first guard with isCurrentCacheGeneration(), then
call both markModelsFetchFailure(name) and markProviderDiscoveryFailed(...)
using the existing reason mapping, before returning the degraded catalog.

In `@src/oauth/devin.ts`:
- Line 97: Update loginDevin so result.apiServerUrl is stored in Devin-specific
credential metadata rather than the generic apiBaseUrl field. Validate supported
Devin/Windsurf server URLs, preserve the metadata through normalizeCredential
and refresh, and use it when configuring the Devin provider before
createDevinAdapter consumes provider.baseUrl. Add a regression test covering an
EU or FedStart api_server_url.

In `@src/oauth/devin/register-user.ts`:
- Line 91: Validate the parsed registerApiServerUrl in registerUser before
constructing or sending the RegisterUser request, and reject any endpoint whose
protocol is not HTTPS. Preserve the existing URL normalization and request flow
for valid HTTPS URLs, ensuring firebase_id_token is never sent to an HTTP
endpoint.
- Around line 160-166: Update the RegisterUser response handling around
WindsurfRegistrationError so a missing name does not reject a response with a
non-empty api_key. Default the optional name to an appropriate fallback before
returning the credential, while preserving its use as the optional email display
label in the devin OAuth flow.

In `@src/oauth/devin/types.ts`:
- Around line 34-48: Remove the unused PersistedCredentials interface from the
Devin OAuth types, including its fields and outdated command-specific
documentation. Preserve OAuthLoginResult because it is still required by
registerUser, and leave OAuthCredentials and other active types unchanged.

In `@src/server/claude-messages.ts`:
- Line 812: Remove the Devin adapter from the estimated-usage conditions in
src/server/claude-messages.ts:812 and src/server/chat-completions.ts:156,
leaving only adapters without reported per-turn input tokens. Ensure Devin
routes preserve the accurate usage emitted by the Devin usage event and do not
write JSON-serialization estimates into estimateClaudeRequestTokens or

Extract anySignal into a shared helper with cleanup support. The fallback executes on supported Node 18–20.2 runtimes because package.json allows Node >=18, and AbortSignal.any is unavailable there. Both src/adapters/devin/cloud-direct/auth.ts#L39-L53 and src/adapters/devin/cloud-direct/chat.ts#L57-L71 add { once: true } listeners without removing them when the request completes. Reusing a long-lived caller signal can therefore retain one closure per mint or stream. Move the implementation to src/adapters/devin/cloud-direct/signals.ts, return a cleanup function, and call it in finally after mintUserJwt or streamChatEvents no longer needs the combined signal. Keep the current AbortSignal.any branch and preserve signal cancellation for the full stream lifetime.

CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Reject non-HTTPS API hosts before constructing credential requests

host accepts CloudChatRequest.apiServerUrl, and registerUser copies api_server_url without validating its scheme. buildMetadata places the persistent api_key in field 3 before fetch uses host directly. An HTTP host therefore sends the credential without transport encryption.

Add a shared requireSecureHost resolver. Call it before buildMetadata in mintUserJwt and before any cached-host fast path. Reject non-HTTPS hosts, except loopback hosts if local development requires them. Use the normalized result for the auth, catalog, and chat requests.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

The request-dedup caches store a promise that carries the first caller's abort signal, so one caller's cancellation propagates to unrelated callers. Both modules build a shared in-flight promise by passing the first caller's signal into the underlying fetch, then hand that same promise to every later caller for the same key. The cancellation scope of caller A therefore becomes the cancellation scope of callers B and C. The fix is the same in both places: start the shared work with an internal-only lifetime, and race each caller's own signal against the shared promise.

  • src/adapters/devin/cloud-direct/auth.ts#L216-L219: stop passing signal into mintUserJwt for the shared promise. mintUserJwt already applies its own MINT_TIMEOUT_MS guard. Wrap each caller's await so it rejects on that caller's own signal only.
  • src/adapters/devin/cloud-direct/catalog.ts#L194-L196: stop passing signal into fetchCatalog for the promise stored in inFlight. Keep the internal CATALOG_FETCH_TIMEOUT_MS guard, and race each caller's own signal against the shared promise. Note that fetchCatalog also forwards its signal into getCachedUserJwt, so the auth-side fix is a prerequisite for this one.

Add a regression test near the existing Devin tests: start two concurrent requests for the same api_key, abort the first during the in-flight window, and assert the second still resolves.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

The 10s timeout and the caller signal stop protecting the request before the body is read, so a stalled body blocks chat indefinitely.

fetch resolves when the response headers arrive, not when the body completes. The finally block at Lines 126-129 runs at that moment: it calls clearTimeout(timer) and cleanupOnAbort(), which removes the forwarding listener from the caller's signal. Both body reads happen afterwards — resp.text() at Line 132 and resp.arrayBuffer() at Line 135. Those reads have no timeout and no cancellation path.

Failure mode: the catalog endpoint returns 200 headers and then stalls the body. await resp.arrayBuffer() never settles. ac can no longer be aborted by the timer or by the caller.

The consequence reaches the chat path. streamChatEvents awaits getCachedCatalog before it sends the chat request (src/adapters/devin/cloud-direct/chat.ts Line 827). A stalled catalog body therefore hangs the whole chat turn — precisely the deadlock the comment at Line 102 says this timeout prevents. The .catch(() => null) at chat.ts Line 827 does not help, because the promise never settles.

Fix: keep the guard alive until the body has been consumed.

🐛 Proposed fix — extend the guard across the body read

devin is an accurate-usage adapter, so it must not join the estimated-usage adapter set. Both sites add devin to a list reserved for adapters that report no per-turn input tokens. src/adapters/devin.ts:130-220 consumes a usage cloud event and emits real inputTokens/outputTokens on the terminal done event. finalizedUsage in src/server/request-log.ts:1199-1208 then applies Math.max(reported, estimate) and stamps estimated: true, so a JSON-serialization estimate that exceeds the provider count silently replaces the accurate value — the exact regression the comment at src/server/claude-messages.ts:808-811 prohibits (audit 133 R1#7).

  • src/server/claude-messages.ts#L812-L812: remove || route.provider.adapter === "devin" from the condition, or gate the estimateClaudeRequestTokens assignment on the absence of reported Devin usage.
  • src/server/chat-completions.ts#L156-L156: remove || route.provider.adapter === "devin" from the condition so the messages/tools estimate is not written to logCtx.usageLogInputTokens for Devin routes.

💡 Result:

As of September 2026, the models you inquired about have the following context window and documentation details: SWE-1.7 Cognition's proprietary coding model for the Devin autonomous agent [1][2]. Context Window: 256K tokens [3][2]. Documentation: Official details are provided via Cognition's blog [1] and referenced in benchmarking and agentic model tracking platforms like BenchLM and Awesome Agents [3][2]. It is not sold as a standalone API model but is bundled into Devin subscription plans [2]. GPT-5.6 Sol OpenAI's flagship reasoning model in the GPT-5.6 family [4][5]. Context Window: 1,050,000 (1.05M) tokens [4][5]. Documentation: Available via the official OpenAI API documentation, Microsoft Foundry Model catalog, and OpenAI product indices [4][6][5]. Claude Fable 5 (and 5.1) Anthropic's high-capability model family for demanding reasoning and long-horizon agentic work [7][8]. Context Window: 1,000,000 (1M) tokens [7][9]. Documentation: Available via the Anthropic Platform documentation, covering specifications, pricing, and migration paths (specifically for the newer 5.1 version) [7][8][10]. Devin Context Awareness Devin Desktop uses an internal RAG-based context engine (including specialized subagents like Fast Context with SWE-grep models) to manage codebase awareness, pinning, and retrieval, rather than relying solely on a single model context window [11][12]. Documentation for Devin's CLI and Desktop features can be found at docs.devin.ai [13][11].

🌐 Web query:

site:cognition.com/blog/swe-1-7 "context" tokens

💡 Result:

In the context of large language models (LLMs), tokens are the fundamental units of text that a model processes. An LLM breaks down input text into these smaller components—which can be characters, sub-words, or words—before performing computations. The context window refers to the maximum number of tokens an LLM can process in a single input sequence, encompassing both the user's prompt and the model's generated output [1]. When an agent or model approaches this context limit, it can no longer incorporate additional information without removing or summarizing existing data [1]. To manage this, techniques such as self-compaction are used, where the model summarizes its current working state to free up space within the context window for continued operation [1].

Do not route Devin through inferCursorContextWindow. inferCursorContextWindow returns CURSOR_DEFAULT_CONTEXT_WINDOW (128,000) when no heuristic matches; it does not return undefined. Therefore the discovered Devin model swe-1-7 reaches capEstimateAtContextWindow with a 128,000-token cap, while gpt-5-6-sol matches the Cursor GPT-5 rule and receives 272,000. Return undefined for devin, or add a Devin-specific map with verified limits and regression tests.

Do not depend on a real home-directory credential.

importLocalPiDevinAuth() returns undefined when ~/.pi/agent/auth.json is absent. Line 60 then fails on clean CI workers because cred?.source is undefined.

Mock the file read and provide a fixture with a valid devin.access value. This verifies the import contract without requiring a developer or CI credential.

Login is now always the Auth0 browser sign-in flow — no more importing
from ~/.pi/agent/auth.json. Removed importLocalPiDevinAuth, the
importLocal/forceLogin opts on loginDevin, and the PiDevinAuthSlot
shape. The OAuth entry in src/oauth/index.ts calls loginDevin(ctrl)
with no opts.

Updated the registry note, adapter error message, and docs to describe
only the browser flow.

The model roster now comes entirely from Cognition's
GetCascadeModelConfigs endpoint, not from a hardcoded static seed.

- fetchDevinUsableModels collapses effort-suffixed variants to base ids
  (e.g. gpt-5-6-sol-high → gpt-5-6-sol) and filters out internal
  MODEL_* enum constants, returning the real callable base models for
  the signed-in account (41 models on the test account, vs 11 hardcoded)
- provider-fetch.ts uses the live-discovered base models directly as the
  roster instead of filtering them through DEVIN_STATIC_MODELS
- The adapter's resolveWireModelUid now consults the cached live catalog
  to pick the exact wire UID the account can serve, instead of a
  hardcoded no-suffix set. Degraded mode still appends "medium"
- DEVIN_STATIC_MODELS is retained only as a degraded-mode fallback for
  when there is no API key or discovery fails
- Removed filterDevinConfiguredModelsByLiveDiscovery (no longer needed)
- Added collapseDevinModelUid regression test

Validated 13 Major findings from CodeRabbit; fixed the 10 that are
real bugs. Skipped 3 defense-in-depth items (apiServerUrl scheme
validation, error message slice) where the host is hardcoded to the
trusted Cognition endpoint.

Fixes:
- Remove devin from estimated-usage adapter set in claude-messages.ts
  and chat-completions.ts — Devin reports accurate usage, so the
  estimate would overwrite real token counts (audit 133 R1#7)
- Default name to "Devin account" when RegisterUser omits it instead
  of failing login
- Call markModelsFetchFailure on Devin discovery failure so
  isModelsFetchCoolingDown engages (matches Cursor branch)
- Construct CatalogModel rows with provider + catalog hints instead
  of bare { id } — fixes routing identity for discovered-only models
- Treat empty catalog (schema drift) as "no catalog" so chat passes
  through instead of failing every request
- Flush pending system text before non-system turns (assistant/tool)
  so system instructions keep their leading position
- Cap Connect-RPC frame length at 16MB to prevent memory exhaustion
  from a corrupt length prefix
- Race each caller's abort signal against the shared in-flight
  promise in getCachedUserJwt and getCachedCatalog so one caller's
  cancellation never propagates to unrelated callers
- Keep catalog fetch timeout alive until after body read — fetch
  resolves on headers, not body completion
- Add cacheEpoch to clearCachedCatalog so an in-flight fetch racing
  with a clear can't repopulate the cache
