CLI Anything Nsight Graphics

Nsight Graphics CLI Skill

Command-line orchestration of official NVIDIA Nsight Graphics activities.

Capabilities

• Probe installed Nsight binaries and compatibility mode
• Launch an application detached under Nsight
• Attach Nsight to a running PID
• Trigger Graphics Capture or OpenGL Frame Debugger capture
• Trigger GPU Trace capture, auto-export, and summarize
• Analyze existing .ngfx-capture files through ngfx-replay
• Report clear compatibility diagnostics for .ngfx-gputrace inputs
• Trigger Generate C++ Capture

Commands

doctor

cli-anything-nsight-graphics --json doctor info

Agent Notes

• Prefer doctor info first to discover the available compatibility mode.
• Use doctor versions to list detected installs when multiple Nsight Graphics versions exist.
• Use --nsight-path to force a specific install directory or ngfx.exe.
• Use --json for programmatic workflows.
• Prefer gpu-trace capture --auto-export --summarize for one-step performance triage. The summary includes exported table inventory, metric inventory, frame-budget classification, workload classification, throughput ranking, bottleneck hints, and warnings for empty event/regime tables.
• Use replay analyze when the input is an existing .ngfx-capture file. With no analysis switches it exports metadata, logs, captured log errors, and a replay performance report, then adds structured analysis.highlights / analysis.warnings.
• ngfx-replay documents its input as a Graphics Capture file. .ngfx-gputrace inputs are accepted for clear diagnostics, but on Nsight Graphics 2026.1.0 they may report Invalid file header; use gpu-trace summarize for exported GPU Trace table analysis.
• replay analyze uses official ngfx-replay metadata/log/screenshot/perf-report outputs; it is not a RenderDoc-style shader, pipeline, texture, or resource inspector.
• Frame/GPU/C++ capture commands require a launch target through --exe or a preconfigured root-level --project.
• If a global cli-anything-nsight-graphics command points at an old worktree, reinstall from nsight-graphics/agent-harness with python -m pip install -e ..
