Outcome

Add explicit local Cline SDK sessions in Python and TypeScript through the same owned Node bridge. Refs TWA-101.

Scope

  • Require caller-installed @cline/sdk@0.0.82 and Node >=22.14; no CLI/ACP fallback or hub operations.
  • Run commands through the public bash executor hook and existing Harness process runners, including cleanup after forced SDK-worker loss.
  • Require explicit builtin-only features; preserve native approval defaults or caller-selected callbacks, exact identity/resume, raw events and per-turn/cumulative usage.
  • Ship public APIs, SPEC, capability docs, release notes, packaged worker and matching native-SDK/synthetic-provider conformance together. Preserve landed OpenHands and Factory Droid support.

Validation

  • Exact-head macOS and Ubuntu CI passed every configured Python, Bun, typecheck/build and packaged Node step: run 34440643927.
  • Local integration acceptance: 174 Python session/Cline/Droid tests, strict TypeScript check/build, and Bun plus packaged Node Cline/Droid conformance. Production teardown deadlines were not relaxed.
  • Exact 39af241 archive built sdist/wheel and npm tarball. Fresh consumers verified imports from installed site-packages and local node_modules; real-SDK/synthetic-provider smoke/conformance passed, including follow-up, exact resume and forced-worker-loss cleanup.
  • Independent Grok 4.6 xhigh Standards and Spec reviews cover 39af241. CodeRabbit's final incremental review completed; its earlier threads are resolved, and its outside-diff OpenHands HTTPS suggestion was assessed against the existing caller-owned TLS contract.

Limits

Native-runtime qualification used Node 22.22.2, disposable configuration and synthetic providers; authenticated-provider generation was not run. Stock SDK/ACP shell execution failed forced cleanup, so ACP and escaping native extensions remain unsupported. No auth/hub operations or package publication. Package metadata is Python 0.3.22 / TypeScript 0.2.27, preserving the documented minor-version skew.

📝 Walkthrough

Walkthrough

This change adds optional Cline SDK sessions for Python and TypeScript, with a Node worker bridge for native Cline execution. It also extends the shared session contract and both runtimes for Factory Droid SDK sessions and caller-owned OpenHands sessions. The Python and TypeScript runtimes now share more owned-process and teardown handling. The test suite adds Cline conformance coverage, synthetic provider support, worker fault injection, and invalid-option checks. Documentation, release notes, package metadata, and CI steps now describe and validate the new session paths.

- Line 21: Update samePath to tolerate nonexistent paths by using the existing
realpathOrSelf behavior from sessions.ts instead of calling realpathSync
directly, while preserving its current string and absolute-path checks and
equality semantics.

In `@tests/test_cline_sdk.py`:
- Line 39: Bound the provider handshake in the test setup around
provider.stdout.readline() with a 5-second timeout, matching the TypeScript
counterpart, so a missing endpoint fails promptly instead of hanging. Ensure the
watchdog also accounts for the provider’s stderr pipe so startup output cannot
block the helper.

twaldin dismissed coderabbitai[bot]’s stale review September 10, 2026 04:37

Both review threads are resolved: CodeRabbit withdrew the strict-realpath finding, and fdf4e86 fixed bounded provider readiness and stderr draining. Independent Grok 4.6 xhigh Standards and Spec reviews cover final head af26505. Dismissing the stale request-changes state, not recording an approval; the latest optional CodeRabbit review was rate-limited.

Require HTTPS before accepting the OpenHands API key.

openhands.endpoint accepts HTTP, while the session sends apiKey in the WebSocket authentication frame and HTTP requests. An on-path observer can read the key.

Reject non-HTTPS endpoints before creating the transport, and add a rejection test.

Proposed fix
   const endpoint = normalizeEndpoint(raw.endpoint, 'openhands.endpoint')
+  if (!endpoint.startsWith('https://')) {
+    throw invalid('openhands.endpoint must use https because the session API key is sent on every transport')

Assessed the final CodeRabbit review on 39af241. The outside-diff OpenHands plaintext-HTTP risk is real but already explicit in the landed contract: callers select an HTTP(S) origin and own TLS, endpoint trust and server authentication enforcement; HTTP is not encrypted. See the pinned OpenHands contract.

An HTTPS-only rejection would break the documented HTTP server flow and change the existing OpenHands API rather than fix a Cline regression. Keeping that caller-owned transport contract unchanged in this Cline PR; no source change for this suggestion. Both earlier inline review threads are resolved. Independent Grok Standards/Spec reviews and both-platform CI cover this exact head.
