📝 WalkthroughWalkthroughThe Devin adapter restores unique bare tool names to canonical namespaced identities. It rejects ambiguous names with a non-retryable 502 before dispatch, preserves unknown-name validation, documents the behavior, and adds focused tests. ChangesDevin tool identity restoration

리뷰 · 우선순위 74 / 80설명 이 PR은 Devin(Cognition) cloud-direct가 클라이언트 도구를 로컬 이름만 광고한 뒤, 응답에서 그 bare 이름을 그대로 Responses 브리지로 넘기던 구멍을 막습니다. 지금 고침은 요청마다 지금 tip의 Devin 방향( 경로 src/adapters/devin.ts buildDevinReturnedToolNameMap - bare name 충돌을 경로 src/adapters/devin.ts mapDevinToolCallStart - 충돌 시 경로 src/adapters/devin.ts restoreDevinReturnedToolName - 맵에 없는 이름은 원문 유지입니다. 공유 undeclared-tool 가드가 그다음 단계에서 막는다는 전제가 문서·테스트와 일치합니다. 경로 tests/providers/devin-adapter.test.ts - 유일 namespace 복원, canonical이 이미 온 경우, bare 경로 structure/adapters/registry.md - Devin 행에 return map 계약을 적어 둔 점이 좋습니다. 나중에 다른 기여자가 bare→namespace를 다시 빼지 않게 합니다. 메인테이너의 판단이 필요한 지점

Map each unique Cognition bare tool name back to the request-declared Codex identity before bridge validation. Refuse ambiguous local-name collisions instead of selecting by declaration order.

Reject collisions between canonical names and local names.
mapOcxToolsToDevin advertises tool.name, but the adapter also accepts canonical names on return (tests/providers/devin-adapter.test.ts:91-95). The map tracks only local names. For { namespace: "a", name: "x" } and { namespace: "b", name: "a__x" }, it maps a__x to b__a__x. A returned canonical a__x can therefore emit the second tool's identity. src/bridge.ts then resolves that identity through toolNsMap, so the call can dispatch to the wrong client tool.
Register both aliases and mark collisions as ambiguous. Add this case to the collision test.
Proposed fix
function buildDevinReturnedToolNameMap(
tools: OcxTool[] | undefined,
): ReadonlyMap<string, string | null> {
const names = new Map<string, string | null>();
+
+ const addOwner = (alias: string, canonical: string) => {
+ if (!names.has(alias)) {
+ names.set(alias, canonical);
+ } else if (names.get(alias) !== canonical) {
+ names.set(alias, null);
+ }
+ };
+
for (const tool of tools ?? []) {
const canonical = namespacedToolName(tool.namespace, tool.name);
- if (!names.has(tool.name)) {
- names.set(tool.name, canonical);
- } else if (names.get(tool.name) !== canonical) {
- names.set(tool.name, null);
- }
+ addOwner(tool.name, canonical);

}
return names;

Closing as landed: restoring namespaced Devin tool identities is on dev, merged inside lane C's cumulative tip #4487 (merge commit 55bb9f3, verified as an ancestor of origin/dev). Your authorship is preserved by a Co-authored-by trailer in the landed commit itself rather than only in the pull request body, so it counts on your contributor graph. The carry folded the review findings already on this pull request and added regression coverage where the lane found a gap. If you think something from this branch did not make it to dev, say so and I will reopen. |
Carry of lidge-jun#4457 by jeongjin0, with the unresolved CodeRabbit finding on src/adapters/devin.ts folded in. The return map tracked only advertised local names, but the adapter accepts canonical names on return too, which the existing catalog test pins. With { namespace: "a", name: "x" } and { namespace: "b", name: "a__x" }, a returned a__x is both the first tool's canonical identity and the second tool's advertised name. The map resolved it to b__a__x, so src/bridge.ts dispatched the call through the second tool's identity — a tool the caller may not have named. Register canonical identities as aliases of themselves and mark a conflicting alias ambiguous, so that name now fails before dispatch like any other ambiguous bare name. The unambiguous local name and the unrelated canonical name still resolve, and every existing case is unchanged: a single namespaced tool, a duplicate identical declaration, a bare/namespaced collision, and an undeclared name left for the shared guard.
