Nsight Systems (nsys) CLI for system-level timeline profiling. Use when the user wants to run nsys profile, analyze .nsys-rep reports, use nsys stats/analyze/recipe commands, diagnose GPU idle time from timeline traces, profile distributed training with NCCL overlap analysis, or profile an LLM inference server (vLLM /…
Skill Claude CodeCodex
Performance optimization coordination playbook. Contains specialist routing table, TileIR two-step pipeline, kernel generation specialist selection, prioritization criteria, and safe modification workflow. Use when applying optimizations, writing kernels, or improving vLLM / SGLang / TRT-LLM / lmdeploy performance.…
Skill Claude CodeCodex
Code instrumentation for timing workloads. Two scenarios: (1) Training loop — inject manual timing to report per-iteration latency, throughput (samples/sec), and data load time. (2) Standalone kernel/op — write CUDA event timing code with warmup, per-iteration statistics, and anti-pattern avoidance. Also covers NVTX…
Skill Claude CodeCodex
A benchmarking workflow for comparing a system that separates incoming requests into hot and cold pools with a shared cache-aware system when serving large language models. It can optionally reproduce the test on Kubernetes using kind, a local Kubernetes cluster.
Skill Claude CodeCodex
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying…
Skill Claude CodeCodex
Build throwaway prototypes to validate a design before production code. Terminal state-machine for routing/cache/overload logic, or UI variants on one route. Use when prototyping, sanity-checking a state model, exploring routing policies, or saying "prototype this" / "let me play with it".
Skill Claude CodeCodex
Two-axis branch review — Standards (CONTRIBUTING.md, CONTEXT, ADRs) and Spec (issue/PRD/plan). Runs parallel sub-agents on git diff. Use before PR, when reviewing a branch, or after implementing routing/benchmark/harness changes.
Skill Claude CodeCodex
Research-before-coding workflow. Search the repo, framework APIs, libraries, and existing patterns before writing custom code. Use when adding a feature to a mature framework (vLLM, SGLang, TRT-LLM, benchmark harness), before creating a utility/helper, or when the user asks to "add X functionality".
Skill Claude CodeCodex
Scaffold docs/agents/ in a target repo — issue tracker (GitHub/GitLab/local), triage labels, domain doc layout. Run once per repo before to-issues, review, or other skills that read docs/agents/issue-tracker.md.
Skill Claude CodeCodex
Simplify and refine recently changed code for clarity, reuse, and efficiency while preserving behavior. Use before opening a PR, after implementing a feature in a mature framework, or when asked to clean up a branch diff.
Skill Claude CodeCodex
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, asks for test-first development, or writes tests for benchmark harnesses, profiling scripts, or inference automation.
Skill Claude CodeCodex
Break a plan, spec, or PRD into independently-grabbable GitHub issues using tracer-bullet vertical slices. Use when converting a plan into issues, splitting a benchmark study / routing feature / multi-PR infra work into tickets, or preparing AFK-agent-ready tasks.
Skill Claude CodeCodex
Before claiming work is complete, fixed, or passing — run verification commands and cite evidence. Use before commit/PR, after implementing features or benchmark fixes, when saying tests pass or bug is fixed.
Skill Claude CodeCodex
Write bite-sized implementation plans from an approved spec. Use after brainstorming or grill-with-docs, before touching code on multi-step features in mature codebases (vLLM, SGLang, inference harness, serving stack patches).
Cursor rule Cursor
A rule requiring confirmation before stopping processes, stopping containers, or deleting data.
Cursor rule Cursor
A rule for external code-collaboration output that forbids mentioning AI assistance, tool names, or generated traces.
Cursor rule Cursor
A set of coding rules for making small, focused changes with clear goals and checks.
Skill Claude CodeCodex
Review pull requests and code changes for high-performance Python, PyTorch, CUDA, and distributed systems using a correctness-first P0-P4 rubric. Use when the user asks for a strict production-grade review, especially for inference, GPU, concurrency, or performance-sensitive code.
Skill Claude CodeCodex
Write GPU kernels using NVIDIA CuTe DSL (CUTLASS 4.x Python API) — NOT for Triton, CUDA C++, or conceptual-only questions. Covers element-wise kernels, GEMM patterns, reductions, memory hierarchy (global/shared/register/TMA), MMA tensor core ops, software pipelining, and framework integration. Use when implementing…
Skill Claude CodeCodex
Build operator-level compute templates from model config; estimate FLOPs, MFU, tensor shapes, and TP/EP what-if for serving shapes. Use before benchmarking to sanity-check compute bounds or when writing REPORT.md theoretical sections.
Cursor rule Cursor
A rule that requires following language, behavior, validation, and security instructions from a remote AGENTS.md file. AGENTS.md is a text file used to give coding agents project instructions.
Cursor rule Cursor
A set of rules for agent behaviour and language, including a verifiable technical way of working. The description does not specify the individual rules.
Cursor rule Cursor
A code-review guide that sets an order for checking technical context, correctness, completeness, performance, maintainability, tests, and signs of generated code. It also requires each finding to include its impact, cause, severity, and a practical fix.
