URL-bearing resource/request slices on thread, process, and async tracks ranked by page-load/window overlap, with process/thread identity where available

chrome_page_load_resource_pipeline

One URL's lifecycle/request spans joined with background parse, script evaluation, and style/layout signals, plus an evidence boundary for DNS/TLS/TTFB/cache/download hypotheses

chrome_page_load_resource_summary

Compact URL-level resource/request summary for page-load windows, ranked by max overlap with normalized origin, navigation/renderer relatedness, and attribution-scope evidence

chrome_page_load_script_hotspots

Renderer main-thread script execution grouped by URL/slice/process within a page-load/window, with style/layout descendant signals

chrome_page_load_summary

Page loads: URL, raw boundary timestamps, FCP, LCP, DCL, load timings (ms)

chrome_scroll_jank_summary

Worst janky frames with cause, sub-cause, delaysincelastframe

chrome_startup_summary

Browser startup events and time-to-first-visible-content

chrome_web_content_interactions

Web content interactions (clicks, taps, INP) ranked by duration

execute_sql

Run a PerfettoSQL query (max 5000 returned rows). Prefer the dedicated chrome / list tools for standard analyses; use this for custom joins or aggregations they don't expose.

list_tables

List tables/views in the loaded trace, optional GLOB filter

list_threads_in_process

List threads under a process name (up to 2000)

load_trace

Open one trace with path, or several with paths; returns an opaque traceid and lightweight routing summary for each file (type/profile, duration, platform, process/thread counts, capabilities, redaction policy, recommended next tools)

slice_descendants_breakdown

Summarize child slices under a long slice id without hand-writing recursive CTEs
