ConsoleMessages
ChatGPTShow console API messages (console.log, console.warn, console.error, etc.). Note: console errors are distinct from runtime exceptions — use UncaughtException and ReactException for those. Start with mode 'summary' for an overview with message counts and the last errors/warnings. Use 'messages' to browse the full paginated list (filter by level, text, node_modules visibility). Use 'message-detail' with a point reference for full detail on a single message including stack trace. Call RecordingOverview first for broader context.
DescribePoint
ChatGPTDescribes the application state at a code execution point. Shows the containing function with executed/not-executed annotations, variable values, and timestamps. Use dependencyChain=true to trace the full causal chain back to the origin event. Get execution points from other tools (ConsoleMessages, ReactRenders, ReduxActions, Logpoint, etc.).
Evaluate
ChatGPTEvaluates an expression at a code execution point. Use for ad-hoc value inspection beyond what DescribePoint shows. Supports any JS expression.
ExecutionDelay
ChatGPTComputes execution delays for functions based on their source length and the delay before the first breakpoint in each function executes. Each breakpoint is attributed to the innermost function covering it, and each function's weight is computed as its source length minus the sum of its children's lengths.
GetPointComponent
ChatGPTGets the React component being rendered at a code execution point.
GetPointLink
ChatGPTGenerates an app.replay.io link for users to inspect a given execution point.
GetStack
ChatGPTGets the call stack at a code execution point. Use to understand execution context. Pair with DescribePoint for full state.
InspectElement
ChatGPTGet size, layout, ancestry and render point information for a DOM element. Find relevant code before inspecting elements. Only use this tool sparingly — expensive, requires full DOM layout computation. Prefer ReactComponentTree for component structure.
ListSources
ChatGPTList the sources in the recording.
LocalStorage
ChatGPTDescribe all the accesses made to localStorage. Start with mode 'summary' (default) for a grouped overview: keys with access counts, final values, and timing. Use 'operations' to browse the full chronological access list with pagination. Use keyFilter to narrow by key name (substring match). For large apps, consider filtering by key pattern in results.
Logpoint
ChatGPTEvaluates an expression at breakpoint hits for a given path and line number. Returns up to 20 hits with their expression evaluation results. Use beginPoint/endPoint to narrow the range. Use column to target a specific statement on the line. Find source paths with ListSources or SearchSources first.
NetworkRequest
ChatGPTAnalyze network requests in the recording. Start with mode 'summary' (default) for high-level stats: total count, failed/slow counts, status code distribution, and top domains. Use 'requests' to browse a paginated table of all requests (filterable by urlFilter, startTime, endTime). Use 'detail' with requestIndex (from the 'requests' table) or requestId for full request/response headers, body content, event timeline, and backend function analysis. RECOMMENDED workflow: summary → requests → detail. Call RecordingOverview first for broader context about the recording.
PlaywrightSteps
ChatGPTShow all steps taken by Playwright in the recording. Start with mode 'summary' for a test overview with pass/fail status and duration. Use 'steps' with testIndex to see the step list for a specific test (get indices from 'summary'). Use 'step-detail' with stepNumber for inspector protocol commands of a single step (get step numbers from 'steps'). Use 'test-source' with testIndex to read the test source code. For failed tests, use failedOnly=true in 'steps' mode to focus on failures. Call RecordingOverview first for broader context.
ProfileGraph
ChatGPTProfiles dependency graph entry execution between two points in a recording. Enumerates all dependency graph entries including React fiber renders and effect calls, computes the execution associated with each by progress counter differences, traces each entry back to its source via the dependency chain, and groups results by source ordered by execution amount.
ProfileSampling
ChatGPTProfiles the native C++ replay engine using stack sampling between two execution points. Runs the replay engine from the begin point to the end point while collecting periodic stack samples, then analyzes the samples to produce a flat profile of where time is spent in native code.
ProfileStatements
ChatGPTProfiles JS statement execution between two points in a recording. Fetches all breakpoint hits between the points, breaks them down by function, resolves function names, and computes a flat profile and call tree showing statement hits per function and its callees.
ReactComponentTree
ChatGPTGet the structure of the React component tree at a point in time. Start with mode='summary' for an overview of component counts and top-level structure. Use mode='tree' to see a paginated, depth-limited hierarchy with collapse markers. Use mode='subtree' with 'component' to focus on a specific component's ancestors and descendants. Use 'nameFilter' to search for components by name. Use 'hideFilter' to remove noise (e.g. Provider, Consumer). For render-level analysis (timing, waste, causes), use ReactRenders instead.
ReactException
ChatGPTDescribe any exceptions thrown which caused React to unmount. This finds React error boundary crashes and render-phase exceptions. For non-React uncaught exceptions, use UncaughtException instead. RecordingOverview includes an error summary — call that first for context.
ReactRenders
ChatGPTAnalyze React renders in a recording. Start with mode 'summary' for a recording-wide overview of commits and render time. Use 'waste-rank' to find components with the most wasted renders. Use 'commits' to browse render commits chronologically. Use 'commit' with commitIndex for single commit detail (get indices from 'commits'). Use 'component' with componentName to see a component across all commits (get names from 'waste-rank'). Use 'fiber' with fiberId to see all renders for a specific fiber instance (add includeProps=true for prop values at each render). Use 'trigger-detail' with commitIndex to trace the dependency chain (click, network, dispatch) that triggered a commit. Use 'commit-fibers' and 'fiber-cause' for fiber-level causation analysis. Call RecordingOverview first for broader context.
ReadSource
ChatGPTRead up to 50 lines of code centered around the given line and see what statements executed.
RecordingOverview
ChatGPTProvides a comprehensive overview of a recording: test results, errors, environment info, network activity, React render performance, and suggested next investigation steps. Call this first to understand what happened in a recording before diving into specific tools. NOTE: The first call on a cold recording may take 3-4 minutes while initial data is computed. Set a longer timeout for this tool. Subsequent calls will be fast.
ReduxActions
ChatGPTAnalyze Redux actions in a recording. Currently covers Redux/RTK dispatches via source-level instrumentation. Start with mode 'summary' to see action type frequency and correlation stats. Use 'actions' to browse dispatches chronologically (filterable by actionType substring). Use 'action-detail' with actionIndex for full correlation data: timing breakdown, selector stats, component render timings, and dispatch origin location. Use 'impact' with actionIndex for a render impact report with optimization recommendations. Use 'state-shape' to see a lightweight key/type listing of the state tree (~200–400 tokens). RECOMMENDED: use state-shape FIRST to understand the state structure, then drill in. Use 'action-state' with actionIndex to see actual state values at a dispatch point. STRONGLY RECOMMENDED: use the 'path' param (e.g. path='auth.user') to drill into specific subtrees instead of dumping the entire state tree. Call RecordingOverview first for broader context about the recording.
Screenshot
ChatGPTLists all screenshot timestamps in the recording, or fetches a screenshot at a given timestamp. Call without timestamp to list all available timestamps. Call with timestamp to get a screenshot URL with mouse position, movements, and time since last click. Set base64=true for raw image data. RecordingOverview suggests a key screenshot timestamp — call that first.
SearchSources
ChatGPTSearch the sources in the recording and see which statements executed. Note: Playwright test runner code runs in Node outside the browser recording and won't appear here. Use PlaywrightSteps(mode: test-source) for Playwright test source.
TanStackQueries
ChatGPTAnalyze TanStack Query (React Query) cache events in a recording. Start with mode 'summary' for an overview of all queries with lifecycle stats. Use 'query-events' with queryHash to see the event timeline for a specific query. Use 'query-timeline' for a chronological view across ALL queries. Use 'query-state' with queryHash + eventIndex to inspect cached data at a specific event point. Observer-internal events are filtered by default; use eventType filter to include them. Call RecordingOverview first for broader context about the recording.
UncaughtException
ChatGPTDescribe any uncaught exceptions (runtime errors not caught by try/catch). For React-specific exceptions that unmounted the app, use ReactException instead. RecordingOverview includes an error summary — call that first for context.
UserInteractions
ChatGPTShow all user interactions (clicks and key presses) in the recording. Start with mode 'summary' (default) for interaction counts by type, time range, top keys pressed, and activity timeline. Use 'interactions' to browse a paginated chronological list with point references for DescribePoint, Evaluate, or GetStack. Use type filter ('click' or 'keypress') to narrow by interaction kind. Useful for understanding the sequence of user actions that led to a bug.
ZustandStores
ChatGPTAnalyze Zustand stores in a recording. Start with mode 'summary' to see all stores and their setState call counts. Use 'store-events' with a storeId to browse setState calls chronologically. Use 'store-state' with storeId and eventIndex to inspect the state at a specific setState call (shows the updater identity, incoming changes, merged result, and previous state). Call RecordingOverview first for broader context about the recording.
