Key features include instruction in forms, push hands, and cultivating whole-body coordination through relaxed alignment.

This skill performs an exhaustive bulk extraction of feature flag names from a binary's namespace to build a complete inventory, cross-referencing them against documented sets to track progress. It distinguishes between gate and telemetry calls, provides completeness metrics, and is designed for campaigns that require a verifiable end condition. Use it upstream when you need a full catalog of flags, not just a sample, for systematic reverse-engineering or probe campaigns.

This skill helps developers systematically survey and synthesize theoretical literature on a given topic. It identifies seminal papers, key results, open problems, and cross-domain connections. Use it to kickstart research on an unfamiliar field, write literature reviews, or evaluate the novelty of a proposed contribution.

This skill provides a comprehensive framework for designing and executing insect population surveys, including sampling design, taxonomic identification, and biodiversity analysis. It calculates key ecological indices like Shannon-Wiener and Simpson's, performs statistical analyses, and generates reports. Developers should use it for baseline biodiversity assessments, environmental impact monitoring, and conservation planning.

This Claude Skill automates the complete workflow for submitting an R package to CRAN, including pre-submission checks and preparing the required `cran-comments.md` file. It handles initial releases, updates to existing packages, and re-submissions after reviewer feedback. Developers should use it when their package passes local checks with zero errors and warnings and has an updated version number.

This skill provides mystical correspondences and meditation techniques for the 22 Hebrew letters, drawing from Kabbalistic sources like the Sefer Yetzirah. Developers can use it to retrieve a letter's numerical value, elemental associations, and its classification as a mother, double, or simple letter. It is designed for studying the letters' symbolic dimensions beyond linguistics, including their paths on the Tree of Life.

This skill systematically solves trigonometric equations and triangle problems using identities, laws of sines/cosines, and inverse functions. It handles equation solving, triangle resolution from partial side/angle info (SSS, SAS, etc.), identity verification, and applied modeling. Use it for finding unknown angles, completing triangles, or real-world trig applications in surveying or physics.

This Claude Skill solves modular arithmetic problems including linear congruences, modular inverses, large modular exponentiation, and systems of congruences using the Chinese Remainder Theorem. It combines manual step-by-step reasoning with computational verification via the extended Euclidean algorithm and Euler's theorem. Developers should use it for number theory tasks involving cyclic groups, discrete log contexts, or simplifying complex modular expressions.

This skill solves electromagnetic induction problems by applying Faraday's law, Lenz's law, and circuit analysis for RL transients. It handles induced EMF from changing magnetic fields or moving conductors, determines current direction, and calculates inductance with magnetic energy storage. Use it when analyzing induction in loops/coils, motional EMF scenarios, or RL circuit switching behavior.

This skill simulates stochastic processes like Markov chains, SDEs, and MCMC samplers, providing sample paths for estimation and prediction. It includes key features like convergence diagnostics, variance reduction, and visualization tools. Use it when analytical solutions are intractable, you need Monte Carlo methods with convergence guarantees, or must sample complex posteriors.

This skill enables developers to design and simulate a minimal CPU from scratch, including defining its instruction set and building the datapath and control unit. It guides you through implementing the complete fetch-decode-execute cycle and verifying the processor by tracing a small program clock cycle by cycle. It's a capstone exercise for composing combinational and sequential logic blocks into a functional "computer inside a computer."

The Shiva Bhaga skill helps developers clear context by identifying and intentionally dismantling stale patterns, outdated assumptions, and dead-code noise. It is designed for use when accumulated context has become cluttered or a major pivot requires a clean slate. This controlled dissolution creates space for new, more effective approaches.

The "shine" skill helps Claude approach adversarial or defensive communication with genuine engagement and luminous clarity instead of force. It is designed for use in high-stakes or oppositional scenarios where standard argumentation fails, aiming to illuminate problems and dissolve resistance. The skill focuses on full presence and authentic investment to achieve resolution.

This skill enables adaptive, polymorphic APIs that present different interfaces based on environment context, similar to a cuttlefish changing its appearance.
