📝 WalkthroughWalkthroughWorkBuddy is added as an experimental OAuth provider. The integration imports local desktop credentials, registers the provider and adapter, maps models, forces streaming requests, sanitizes SSE responses, and delegates parsing to the OpenAI chat adapter. ChangesWorkBuddy provider integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The provider can reuse a cached Authorization header and send one account’s credentials on a later request; the current head also retains authentication-path and non-stream request-contract problems. Merge should be blocked until these issues are fixed. Sequence Diagram(s)sequenceDiagram

Reviewed exact head 281311e. The provider direction may be useful, but this head must not merge yet. I independently confirmed all four current automated findings against the implementation:
- The sanitizer searches only for LF-LF. CRLF-framed SSE is retained until EOF, so a live stream can withhold tokens indefinitely. Consume either delimiter with its full matched length and add a non-EOF CRLF regression.
- buildRequest replaces baseReq.headers instead of preserving them. That drops configured non-auth headers and the base JSON Content-Type. Merge the base headers first, apply auth headers afterward, then explicitly preserve JSON Content-Type and SSE Accept; test both.
- forceLogin passes importLocal off, but local desktop-session import is the only WorkBuddy login mechanism implemented here. A forced re-login therefore disables the only usable path. Keep the fallback enabled and add the force-login regression.
- Missing, non-numeric, non-positive, or overflowed expiresAt normalizes to 0 or a non-finite value and the session is still accepted. Reject those sessions before constructing or caching credentials and cover each malformed shape.
The existing focused suite is green (16/16) and typecheck passes, but it does not exercise these boundaries. Please fix the four cases, resolve the current threads, update onto latest dev, and rerun exact-head CI. Because this adds a desktop-session authentication surface, maintainer sponsorship should come only after those fixes and a fresh auth-boundary review.
Recognize CRLF SSE delimiters, merge base request headers, keep forceLogin on local import, and reject malformed desktop session expiry before caching credentials. Co-authored-by: Cursor <cursoragent@cursor.com>

Re-reviewing exact head 2821852d849c7d6a07b8ce2c58bde2e7ff175239 after the auth-boundary update. The four blockers from the previous review are fixed: CRLF records stream before EOF, configured headers and JSON/SSE media types are preserved, forced login still imports the desktop session, and malformed expiry values are rejected. The focused WorkBuddy suites pass 21/21; typecheck and privacy scan are clean.
One security/correctness blocker remains in src/adapters/workbuddy.ts. baseReq.headers is merged as a plain object before the WorkBuddy Authorization value is added. Header names are case-insensitive, but object keys are not: a configured lowercase authorization survives beside uppercase Authorization, and fetch combines or forwards both values. That can break WorkBuddy authentication and can send an unintended configured credential to the WorkBuddy endpoint.
Please construct a Headers object from the base headers, use set() for every WorkBuddy authentication header plus Content-Type and Accept, then convert it back to the adapter's record shape. Add a regression with a lowercase configured authorization asserting that exactly the WorkBuddy bearer remains.
I independently checked the new non-stream suggestion and do not consider it a blocker: this adapter intentionally forces the upstream WorkBuddy request to SSE and implements parseResponse by consuming that stream for non-streaming downstream clients. Rejecting the downstream request would remove supported behavior. The function comment should ideally say that forcing upstream streaming avoids WorkBuddy error 11101, because its current wording is easy to misread.
Keep the PR unsponsored and unmergeable until the case-insensitive credential-header boundary is fixed, the remaining thread is resolved, and exact-head CI is green.

Reviewed exact head 67acb3313e8f8f9c6c6ee24fb06e881f8fcaf965. The case-insensitive Authorization collision is fixed correctly, and local verification passes: 23/23 focused tests, typecheck, and privacy scan.
I am still requesting changes and am not applying maintainer-sponsored because the current authentication boundary is not safe or policy-complete:
- The request bearer and the WorkBuddy identity metadata are not taken from one OAuth snapshot.
responses/core.tsresolves the active stored credential and puts its access token inroute.provider.apiKey, butworkBuddyHeadersFromProviderseparately rereads the current desktop file forX-User-Id, domain, and enterprise identity. If the desktop app switches accounts while the stored token remains valid, one request can combine account A bearer with account B identity headers. Carry the WorkBuddy metadata from the sameOAuthAccessSnapshotinto a request-scoped adapter context (as Kiro does), and never reread the global desktop file during request construction. Add an account-switch regression proving no mixed request reaches upstream. readWorkBuddyAuthHeadersreturns its cached object by reference andworkBuddyHeadersFromProvidermutatesAuthorizationon that object. Remove this mutable shared-header path (preferred once item 1 is fixed), or return immutable copies and test token/account changes across consecutive requests.forceLogin/ add-account currently just reimports the already active desktop identity. Follow the owner direction: an add-account attempt must not silently claim success for the same uid; tell the user to switch the desktop account first, then import and verify that the identity actually differs.- This is a new canonical credential destination.
MAINTAINERS.mdrequires primary-source evidence before sponsorship: official endpoint/model documentation, current terms and legal entity, authorization for this desktop-session routing use, a named maintenance owner, and a verification date. Add the evidence and user documentation, including that refresh is local-file reimport rather than use of the stored refresh token.
The draft/readiness gate is still 0/4 and CI is intentionally blocked on the missing sponsorship. Keep it draft; do not request the label again until these boundaries and evidence are complete.
