pyo3-maturin-bindings
by pmcfadin
"Python bindings for Rust libraries using PyO3 and maturin. Use when working on Python bindings to Rust code, including creating or modifying pyfunction/pyclass definitions, converting types between Rust and Python, handling errors across the FFI boundary, managing the GIL and memory, building wheels with maturin, publishing to PyPI, testing binding code, or debugging binding issues. Tuned for CQLite (Cassandra CQL bindings) with feature parity tracking."
Rust Performance & Safety Patterns
by pmcfadin
Zero-copy deserialization, async I/O patterns, lifetime management, memory-efficient parsing, and safe handling of unsafe code for SSTable parsing. Use when working with performance optimization, memory efficiency, async/await, borrowing/lifetimes, zero-copy patterns, or memory usage under 128MB target.

gpui-entities
by cnwzhu
Entity and context patterns for state management in GPUI. Use when managing component state, implementing entity lifecycle, handling subscriptions, or avoiding common entity access pitfalls.
NEON-SOUL
by live-neon
Automated soul synthesis for AI agents. Extracts identity from memory files, promotes recurring patterns to axioms (N>=3), generates SOUL.md with full provenance tracking. Bundled processing engine — no manual Q&A needed.
consciousness-soul-identity
by live-neon
Discover who you're becoming through your own experience. Automated soul synthesis that reads your memory, finds the patterns you keep returning to, and builds an identity document grounded in evidence — not assumptions.

react-best-practices
by tdimino
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
jetbrains-vmoptions
by buYoung
Provides JetBrains IDE VM options knowledge for version-specific GC selection and memory/performance tuning (JDK 17/21, IDE 222+). Cross-platform only.
go-profiling-optimization
by gopherguides
"Profile and optimize Go performance: pprof CPU/memory/block/mutex profiles, allocation analysis, escape analysis, sync.Pool, GOGC/GOMEMLIMIT tuning, benchmarks with -benchmem, PGO workflow, execution tracing. Use when user asks 'why is this slow', 'is this allocating', mentions pprof/profiling, runs benchmarks, or needs to reduce p99 latency. SKIP for general Go idioms — use go skill."
bench
by gopherguides
"Generates and runs statistically useful Go benchmarks with allocation and profile analysis. Use for benchmark creation or measured performance comparison; do not use for general correctness tests."
building-sales-team
by manojbajaj95
Help users build and scale their sales organization. Use when someone is hiring their first salespeople, deciding when to bring on sales leadership, structuring sales compensation, or transitioning from founder-led sales.
profile
by gopherguides
"Profiles Go CPU and memory behavior, identifies bottlenecks, and verifies measured optimizations. Use for evidence-driven performance work; do not use for benchmark generation alone."
backlink-analyzer
by manojbajaj95
Analyzes backlink profiles to understand link authority, identify toxic links, discover link building opportunities, and monitor competitor link acquisition. Essential for off-page SEO strategy.

by manojbajaj95
Track engagement metrics, measure campaign ROI, and analyze content performance across Instagram, Facebook, YouTube, and TikTok.
optimize
by gopherguides
"Analyzes Tailwind CSS bundle size, source coverage, class usage, and build performance. Use for read-only optimization reports; use --fix only when safe project changes are requested."
competitor-analysis
by manojbajaj95
Analyze competitive landscape to identify strengths, weaknesses, opportunities, and threats. Inform product strategy and positioning based on market insights.
analyze-docker-build-errors
by dykyi-roman
