TASTE.md review of the changed code only. Checked: parity (T-1, T-2), configuration/env-var resolution (T-49, T-50, T-51), errors (T-57–T-64), deprecation/compatibility (T-65, T-66), the logging/API-client paths (T-46, T-60), and docstrings (T-69–T-71).
2 violations, both in the Code Interpreter fallback error path, which this PR rewrites in both languages:
packages/code-interpreter-js/src/messaging.ts: the default branch drops the response body, so JS and Python no longer report the same failure the same way (T-1, T-62).packages/code-interpreter-python/e2b_code_interpreter/models.py: an empty body produces a bare"500: "with no reason phrase (T-61). The format also diverges from JS (T-1).
Everything else complies. The removal is symmetric across JS, sync Python and async Python. ConnectionConfig resolution and User-Agent building go back to their prior form in both SDKs. The logger hooks are once again installed only when a logger is passed. The return request / return response added in createApiLogger is fine.
Not tied to a line: Python ConnectionConfig.request_source was a public (non-underscored) attribute in the last release. Removing it in a patch is fine only because it was never documented or meant for users, which is also why it should have been _request_source in the first place (T-18). Nothing to do here beyond being aware of it for T-65.

🟡 Cloudflare suites lose worker limits
When Cloudflare suites pass maxWorkers, the helper now ignores it. Their one-worker caps vanish, allowing concurrent live tests to exceed the shared sandbox budget.
Learn more
The shared Cloudflare Vitest helper used to forward maxWorkers to Vitest. Cloudflare suite configs, Desktop suite configs, and JS SDK suite configs still pass that option. Without forwarding it, Vitest picks its own worker concurrency, and the live-sandbox suites no longer honor their one-worker cap.
Example: The Code Interpreter Cloudflare suite passes maxWorkers: 1. The helper drops the value, so two test files can run concurrently instead of serially.
Recommended fix: Restore maxWorkers in CloudflareVitestConfigOptions, destructure it in createCloudflareVitestConfig, and forward it in the returned test options.

The Cloudflare helper no longer accepts or emits maxWorkers, while all three Cloudflare config callers still pass it and the CI workflows still set E2B_TEST_MAX_WORKERS: 1 (for example, the Code Interpreter workflow explicitly says this keeps one live-sandbox worker). Consequently those Cloudflare live-test runs are no longer constrained to one worker and can again multiply concurrent sandbox work, reintroducing the shared-production overload and flaky-CI risk that the cap was added to prevent. Keep maxWorkers in the option type/destructuring and forward it into test.maxWorkers.

🔴 Removing the maxWorkers option from createCloudflareVitestConfig silently breaks worker-concurrency caps for two callers that still pass it. packages/js-sdk/tests/runtimes/cloudflare/vitest.config.mts:36 and packages/code-interpreter-js/tests/runtimes/cloudflare/vitest.config.mts:6 still call createCloudflareVitestConfig({ maxWorkers: ... }), but the function no longer destructures or forwards maxWorkers into the returned test config, so the value is silently dropped at runtime. code-interpreter-js's suite, previously pinned to maxWorkers: 1, now runs with vitest's default worker parallelism against workerd. Fix: keep accepting and forwarding maxWorkers in CloudflareVitestConfigOptions/the returned test block, or update both call sites to drop the now-ignored option.
Why this was flagged
Both packages/js-sdk/tests/runtimes/cloudflare/vitest.config.mts:36 and packages/code-interpreter-js/tests/runtimes/cloudflare/vitest.config.mts:6 pass maxWorkers to createCloudflareVitestConfig. After this diff, the function's destructured params and returned test object (vitest.cloudflare.config.mts:34-87) no longer include maxWorkers, so it is silently discarded. On base, code-interpreter-js's Cloudflare worker test run was pinned to a single worker; now it runs with default parallelism in CI (code_interpreter_js_tests.yml, js_sdk_tests.yml), which can overload the Cloudflare Workers test pool / miniflare instances and cause flaky or resource-exhausted CI runs. No safeguard catches this because vitest config files are not type-checked before being loaded.
Verification: The candidate is factually correct and the drop is reachable at runtime. Base vitest.cloudflare.config.mts forwarded the option (interface, signature, and returned test object); the diff deletes all three.

Summary
Removes the
E2B_USER_AGENT_SOURCEenv var added in #1794, so SDK behavior no longer depends on whether code runs in CI. The variable shipped in the last release, so this PR includes a patch changeset fore2b,@e2b/python-sdk,@e2b/code-interpreterand@e2b/code-interpreter-python.What goes away (js-sdk, python-sdk, both Code Interpreter SDKs):
ConnectionConfig.requestSource/request_sourceand thesource/<value>token in the User-Agent.?source=<value>on Code Interpreter Jupyter requests.getJupyterRequestUrl/_jupyter_request_urlare removed and the URLs are back to${jupyterUrl}/executeetc.=== 'ci'paths:loggeris passed (no fallback toconsole.erroror thee2b.cilogger);X-E2B-Trace-IDin log lines;(trace_id=…)suffix in Code Interpreter errors (theincludeDiagnostics/include_diagnosticsargs are removed).E2B_USER_AGENT_SOURCE: ciin every workflow,vitest.cloudflare.config.mtsand the Cloudflarewrangler.jsonc.Code Interpreter errors for statuses other than 404 and 502 now produce the same message in both SDKs, in every environment:
For example, an empty 500 is now
500 Internal Server Errorin both, instead of500:in Python.The rest of the runtime code goes back to how it was before #1794 (the inverse of that PR's diff for these paths). Tests that only covered this feature are removed.
messaging.test.tsandtest_format_exception.pynow cover the fallback error message. The kernel-readiness retry helpers intests/setup.tsandconftest.pynow match500 Internal Server Errorexactly.The rest of #1794 is unchanged: the Desktop readiness fix, the Bun pin, the worker limits and the test hardening.
