“Debugging”

Something is broken, failing, crashing or behaving wrong.

A 4-phase root cause debugging methodology to diagnose and fix failures without trial-and-error code guessing.

Debug numerical mismatches in Intel XPU CuTe/CUTLASS kernels, especially Xe DPAS/BDPAS fragment layouts, block-scale payloads, and fused SDPA/GEMM accumulators.

Systematic hook debugging workflow.

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes

UE5.6/UE5.7 debugging and validation workflow for logs, asset checks, and regression triage.

Use this skill for failing tests, compiler or interpreter errors, runtime exceptions, incorrect behavior, build failures, and regression diagnosis in any…

Diagnose and fix failed Quantum ESPRESSO calculations using only the relevant input/output/log artifacts.

Diagnose unexpected Reconify results.

4-phase systematic debugging: investigate, blast radius scan, root cause identification, TDD fix.

Disciplined diagnosis loop for hard bugs and performance regressions.

Use for bugs whose cause is not localizable — intermittent or flaky failures, "works on my machine", regressions with no stack trace, heisenbugs, wrong…

Reproduce and fix a deterministic test, smoke, runtime, or packaging failure with a regression test and documented evidence.

Use when a worker stalls, repeats errors or loses the task intent.

Use when UI state or returned content disappears, flashes, rolls back, saves but loses state, menus fail intermittently, or real browser behavior differs from…

Diagnose Local Coding Agent tunnel, DNS, TCP, TLS, proxy, organization, and office-network blocking issues.

Debug PWAs in your real browser via MCP: service-worker, cache, installability & framework state.

Diagnose failed Quark Torch PTQ installation, execution, script generation, or export attempts.

Diagnose gamepad-ui-engine 1.0.1 input, focus, custom-host transport, and lifecycle failures in a consumer application.

You are an error tracking and observability expert specializing in implementing comprehensive error monitoring solutions.

Diagnose CI/CD production deploy failures from screenshots, workflow logs, and environment evidence.

Systematic debugging with hypothesis tracking — reproduce, hypothesize, test, narrow, fix.

Use when working with error debugging multi agent review

Debug and verification workflow for runtime-bundle and module-resolution regressions.
