Adds three things learned while testing the devMode change end-to-end against the staging embed: (1) assert iframe.src verbatim and explicitly check for dev_mode=undefined when a default is removed from DEFAULT_PARAMS; (2) add a raw window.addEventListener("message") observer before the SDK's embedInitId gating to diagnose launch timeouts, including which replies do and do not echo the id; (3) run Parcel from the package directory, clear .parcel-cache on deserialize errors, and use ss -ltnp/pkill -f since lsof is absent. Also records that a devMode: true launch against staging intermittently timed out once and passed on every rerun, so that case should always be run twice.

Review Change Stack

Note

Reviews paused

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

Use the following commands to manage reviews:

  • @coderabbitai resume to resume automatic reviews.
  • @coderabbitai review to trigger a single review.

Use the checkboxes below for quick actions:

  • ▶️ Resume reviews

Walkthrough

Added a testing skill that documents staging setup, importer and React harness workflows, cross-origin uploads, failure scenarios, diagnostics, required secrets, and cleanup procedures.

Changes

SDK harness testing

Layer / File(s) Summary
Staging harness setup
.agents/skills/testing-sdk-harnesses/SKILL.md
Documents staging authentication, JWT setup, harness startup, troubleshooting, local-source testing, and multi-instance observability.
SDK interaction and validation
.agents/skills/testing-sdk-harnesses/SKILL.md
Documents cross-origin file injection, iframe interaction, launch failure assertions, React rejection detection, and iframe URL checks.
Diagnostics and cleanup
.agents/skills/testing-sdk-harnesses/SKILL.md
Documents raw message tracing, staging-specific diagnostics, required secrets, and cleanup steps.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 7a45b

The updated testing guidance can validate the wrong code revision and can report a clean harness when captured files were actually changed, leading to misleading test results. These bounded correctness issues should be fixed or explicitly accepted before merging.

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Security Check

Explanation

The PR adds an unsafe cleanup command. Line 146 archives every non-ignored untracked file into the predictable /tmp/harness-baseline-untracked.tgz. This can include .env files and credentials. The archive is not used by the later verification commands. With the observed umask 0022, a reproduced archive was mode 0644 in world-searchable /tmp, so local users can read its contents. The PR therefore introduces an unaddressed local secret-disclosure risk.

Resolution

Remove the plaintext archive command. If content snapshots are required, store only hashes in a mktemp -d directory with mode 0700, use umask 077, handle filenames safely, and delete the temporary snapshots after verification. Apply the same protection to /tmp/harness-baseline.patch, which can also contain sensitive tracked changes.

- Around line 22-24: Document that the local JWT server used by the harness must
support CORS for the harness origins localhost:4242 and localhost:4243,
including Access-Control-Allow-Origin on token responses, or expose the endpoint
through the harness origin instead; keep the existing secret-handling and
token-fetch behavior unchanged.
- Line 42: Update the cleanup guidance in the testing SDK harness instructions
to remove broad whole-directory restoration commands such as git checkout --
packages/importer-react/src. Instead, direct users to use a dedicated worktree
or inspect git diff and revert only the exact harness edits, preserving
unrelated uncommitted changes.
- Around line 29-30: Update the testing harness instructions around the yarn
test commands to explicitly require running each long-running server in a
separate terminal, or provide safe backgrounding and cleanup instructions.
Preserve the existing ports and package-specific commands.

- Line 131: The harness cleanup instructions should preserve pre-existing
worktree state: capture the initial git status before running, remove or revert
only files and edits introduced by the current run, and compare the final status
against that baseline rather than requiring an empty status. Update the cleanup
guidance near the harness workflow without deleting unrelated untracked scratch
files.
