🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Walkthrough

Replaces adaptive MSP timeout/flags with a fixed TIMEOUT and simplifies send_message; removes jumbo-frame tracking; adds dynamic import bootstrap for MSP debug tools and many new debug modules (README, barrel, dashboard, queue monitor, stress tester, test runner); treats test environments as compatible and bumps one test API version.

Changes

Cohort / File(s)	Change Summary
MSP core changes src/js/msp.js	Removed messageIsJumboFrame and JUMBO_FRAME_SIZE_LIMIT; removed adaptive MIN_TIMEOUT/MAX_TIMEOUT/timeout; added fixed TIMEOUT = 1000; per-request start timestamp added; simplified connection check and duplicate detection; timer created only for new requests; timer callbacks log long-run warnings and clear timers; removed adaptive timeout scaling; adjusted send/callback invocation semantics.
MSP helper adjustment src/js/MSPHelper.js	process_data now invokes callbacks only when there is no CRC error (removed callbackOnError handling); timer cleanup and callback removal preserved.
Main bootstrap src/js/main.js	Added dynamic import of ./msp/debug/msp_debug_tools.js with dev logs and failure warning; made firstRun retrieval null-safe (getConfig("firstRun") ?? {}) and guarded static-tab initialization.
Browser compatibility src/js/utils/checkBrowserCompatibility.js	Added isTestEnvironment detection (Node/Jest) and treat test environments as compatible in the compatibility check.
Tests test/js/msp/MSPHelper.test.js	Bumped API version constant from API_VERSION_1_46 to API_VERSION_1_47; removed callbackOnError: true from one test entry.
Debug tooling barrel & wiring src/js/msp/debug/index.js src/js/msp/debug/msp_debug_tools.js	New barrel and wiring file: re-exports debug modules, prints console banner, and auto-starts basic monitoring on dev hosts via dynamic import and status listener.
Debug documentation src/js/msp/debug/MSP_DEBUG_README.md	New README documenting MSP Debug Tools features, APIs, usage, tests/scenarios, dashboard interactions, and troubleshooting.
Debug dashboard UI & API src/js/msp/debug/msp_debug_dashboard.js	New MSPDebugDashboard class and exported singleton mspDebugDashboard; builds DOM/CSS UI, canvas live metrics, pause/resume behavior, keyboard shortcut, throttled rendering, and exposes window.MSPDebug API.
Queue monitor instrumentation src/js/msp/debug/msp_queue_monitor.js	New MSPQueueMonitor class and lazy mspQueueMonitor proxy; instruments MSP methods to collect metrics, alerts, thresholds, listener notifications, analysis, reporting, and supports destroy/restore.
Stress test harness src/js/msp/debug/msp_stress_test.js	New MSPStressTest class and lazy mspStressTest wrapper implementing nine stress tests, suite runner, integration with monitor, reporting/grading, and public test APIs.
Browser test runner src/js/msp/debug/msp_test_runner.js	New MSPTestRunner exposing quick monitoring, runTest/runFullSuite, analyze/report, stress scenarios, quickHealthCheck, and global window.MSPTestRunner.

Pre-merge checks and finishing touches

❌ Failed checks (1 warning, 1 inconclusive)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.
Description Check	❓ Inconclusive	The PR description lists the main intents (fixed timeout, test fixes/updates, and added MSP monitoring tools) with checkboxes and screenshots, so it conveys high-level objectives, but it does not follow the repository template structure nor does it document several review-critical details. Missing items that affect reviewability include explicit mention of breaking or public API changes (the send_message signature change and removed properties/constants), a concise file-level summary of the large new debug modules (paths and exported/global APIs), and CI/test results or reproduction instructions for the "fix yarn test" claim. Because those omissions materially affect reviewers and downstream consumers, I cannot conclusively mark the description as complete.	Expand the PR description to include a concise list of changed files/modules (notably src/js/msp.js and the new src/js/msp/debug/* files), explicitly document any breaking API changes (send_message signature, removed constants/properties), and add CI/vitest output or a link plus reproduction steps for the test fixes; also note the new global APIs (window.MSPDebug, window.MSPTestRunner) and whether consumers must update integrations, and confirm the intended commit/squash strategy before merge.

✅ Passed checks (1 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title "Improve msp send" is concise and directly reflects the core changes to the MSP send logic in src/js/msp.js (fixed TIMEOUT, send_message refactor, jumbo-frame cleanup), so it is related and specific rather than generic. However the PR also introduces substantial new debugging and testing tooling (msp debug modules, queue monitor, stress tests, dashboard) and test updates which the title does not surface. Under the repository's guidelines a focused, partially-related title is acceptable, so this check passes. Reviewers would benefit from a slightly broader title or an expanded one-line subtitle to make the full scope obvious at a glance.

@haslinghuis Based on my review of the latest PR status, I can see that CodeRabbit's most recent activity was a "COMMENTED" status (not "CHANGES_REQUESTED") on September 19, 2025, which was after their last review requesting changes. This suggests that the critical issues have been addressed.

The last "CHANGES_REQUESTED" review from CodeRabbit was followed by your response and then a final "COMMENTED" status from CodeRabbit, which typically indicates informational feedback rather than blocking issues.

From the extensive review history, CodeRabbit has provided feedback on:

• MSP timeout handling and retry mechanisms
• Duplicate request detection
• Memory leak prevention
• Debug tools implementation
• Test coverage updates

The current state appears to be that all major requested changes have been addressed. The PR should be ready to proceed unless there are any specific concerns you'd like to address. You may want to do a final check of the CI/build status to ensure everything is passing before merging.
