sglang-dev-tools

Unified SGLang torch-profiler skill for trace generation, kernel/category breakdown, two-stage overlap analysis, and small Perfetto trace repair. Use when Codex should inspect an existing `trace.json(.gz)` or profile directory, trigger `sglang.profiler` against a live server, break down prefill/decode GPU time by kernel family, correlate a graph-off mapping trace with a graph-on formal trace to find overlap headroom tied back to Python code, or rewrite a trace so Perfetto renders overlapped events more reliably.

Guide for writing SGLang CI/UT tests. Covers CustomTestCase, CI registration, server fixtures, model selection, mock testing, and test placement. Always read test/README.md for the full CI layout, how to run tests, and extra tips. Use when creating new tests, adding CI test cases, writing unit tests, or when the user asks to add tests for SGLang features.
