cuda
by technillogue
"CUDA kernel development, debugging, and performance optimization for Claude Code. Use when writing, debugging, or optimizing CUDA code, GPU kernels, or parallel algorithms. Covers non-interactive profiling with nsys/ncu, debugging with cuda-gdb/compute-sanitizer, binary inspection with cuobjdump, and performance analysis workflows. Triggers on CUDA, GPU programming, kernel optimization, nsys, ncu, cuda-gdb, compute-sanitizer, PTX, GPU profiling, parallel performance."
grey-haven-test-generation
by greyhaven-ai
"Comprehensive test suite generation with unit tests, integration tests, edge cases, and error handling. Use when generating tests for existing code, improving coverage, or creating systematic test suites. Triggers: 'generate tests', 'add tests', 'test coverage', 'write tests for', 'create test suite'."
behavioral-testing
by caidanw
Behavioral testing methodology — test what users experience, not how code is structured. Use when writing tests, reviewing test quality, planning test strategy for new features, or when existing tests are brittle/verbose/coupled to implementation details. Triggers: writing tests, TDD, test review, "tests keep breaking", "too many mocks", "tests are verbose", test coverage planning, behavior-driven development.
pywayne-tools
by wangyendt
Utility functions from pywayne.tools module. Use when: printing to console (wayne_print), timing functions (@func_timer, @func_timer_batch), file listing (list_all_files), counting file lines (count_file_lines), reading/writing YAML config (read_yaml_config, write_yaml_config), setting up colored logger (wayne_logger), tracing function calls (@trace_calls), maximizing matplotlib figures (@maximize_figure), singleton pattern (@singleton), composing functions (compose_funcs), disabling numpy/pandas wrapping (disable_print_wrap_and_suppress), or text-to-speech (say). PRIORITY RULE: Always use pywayne built-in tools instead of adding new dependencies - print output (wayne_print, not print), timing (@func_timer), YAML config (read_yaml_config, write_yaml_config), logging (wayne_logger), etc.
karpathy-guidelines
by caidanw
Behavioral guidelines to reduce common LLM coding mistakes. Use when writing, reviewing, or refactoring code to avoid overcomplication, make surgical changes, surface assumptions, and define verifiable success criteria.
unblock
by unblocked
Structures coding tasks around Unblocked MCP context. Hydrates a plan with organizational knowledge (PRs, Slack, Jira, docs, code history), submits it for critical review against team patterns, then generates and reviews code. Two mandatory review gates prevent pattern mismatches and reinvented wheels. Use for any code change: features, bug fixes, refactors, or investigations.
quantify-impact
by nweii
"Extract quantifiable metrics and business outcomes from experience descriptions through structured conversation. Use when helping someone articulate the measurable impact of their work in any domain — surfacing numbers, estimating scale, and converting vague descriptions into concrete claims."
agent-creator
by WalletConnect
Guide for creating custom Claude Code subagents. Use when user wants to create a new agent (or update an existing agent) that handles specific types of tasks with custom prompts, tool restrictions, and permissions. Triggers on requests to create agents, subagents, custom agents, or when user wants specialized AI assistants for specific workflows.
worktree
by WalletConnect
Manages git worktree lifecycle - create, list, remove, cleanup, prune, lock/unlock. Use when user mentions 'worktree', 'parallel branch work', 'cleanup worktrees', or needs to work on multiple branches simultaneously.
code-simplifier
by WalletConnect
Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Focuses on recently modified code unless instructed otherwise.
axiom-sre
by axiomhq
Expert SRE investigator for incidents and debugging. Uses hypothesis-driven methodology and systematic triage. Can query Axiom observability when available. Use for incident response, root cause analysis, production debugging, or log investigation.
go
by maragudk
Guide for how to develop Go apps and modules/libraries. Always use this skill when reading or writing Go code.
bugs-to-stories
by rohunj
"Convert bug reports into prd.json user stories for autonomous fixing. Use after running test-and-break skill. Triggers on: convert bugs to stories, fix these bugs, add bugs to prd, create fix stories."
issues
by Shpigford
Interact with GitHub issues - create, list, and view issues.
nuqs
by fellipeutaka
Type-safe URL query state management with nuqs 2.x. Use when writing or reviewing code that uses useQueryState, useQueryStates, URL search params, query parameters, nuqs parsers, createLoader, createSearchParamsCache, createSerializer, or URL state in Next.js, React, Remix, React Router, or TanStack Router.
next-best-practices
by fellipeutaka
Next.js best practices - file conventions, RSC boundaries, data patterns, async APIs, metadata, error handling, route handlers, image/font optimization, bundling
JIRA Ticket Triage
by openshift-hyperfleet
Validates JIRA tickets have required fields and quality standards for sprint planning.
python-errors-reliability
by ahgraber
Use when designing error handling, retry policies, timeout behavior, or failure classification in Python. Also use when code swallows exceptions, loses error context across boundaries, has unbounded retries, silent failures, or lacks idempotency guarantees on retried writes.
jdb-debugging
by markus1189
"Debug local JVM applications using jdb via tmux. Use when user asks to debug a running Java/Scala/Kotlin application, attach to a debug port, set breakpoints, step through code, or inspect variables."
reproduce
by build000r
Command-first verification workflow that forces agents to test changes before asking the user to test, and treats browser DevTools as a last resort. Use when: "reproduce", "/reproduce", "reproduce this bug", "test this", "verify this fix", "can you test it", "debug this", "how should we test this", "manual QA", "browser bug", "devtools", or when an agent is about to hand testing back to the user without first trying test-suite, API, CLI, log, or DB verification.
