Create dynamic OpenGraph images for social media sharing using Next.js ImageResponse API. Use when adding OG images to new pages, updating existing OG images, or implementing page-specific social previews.

This skill implements test-driven development workflow using the red-green-refactor cycle. Use when building new features or fixing bugs that require test coverage. Framework-agnostic methodology that works with any testing framework and programming language. Triggers on requests to implement features using TDD, write tests first, or follow test-driven development practices.

Guidance for analyzing log files and generating summary reports with counts aggregated across multiple date ranges and severity levels. This skill applies when tasks involve parsing log files by date, counting occurrences by severity (ERROR, WARNING, INFO), and outputting structured CSV summaries across time periods like "today", "last 7 days", or "last 30 days".

Develop and modify the AILANG Collaboration Hub UI. Use when user asks to add features to the monitoring dashboard, modify the approval queue, update the message center, or make changes to the React frontend.

Research competitor pain points from review platforms (G2, Capterra, Reddit) to find wedge opportunities. SaaS/B2B focus. Use for market validation, competitive analysis, or deciding whether to build. Always concludes with brutally honest viability assessment.

Guidance for building MIPS interpreters or emulators that execute MIPS binaries. This skill applies when implementing CPU emulation, ELF loaders, instruction decoders, or syscall handlers for MIPS architecture. Use when tasks involve creating virtual machines for MIPS executables, interpreting MIPS assembly instructions, or emulating MIPS system calls.

Expert guidance on modern React patterns including hooks, composition, state management, and concurrent features. Use when implementing React components or refactoring existing code.

This skill guides writing Infrastructure as Code using OpenTofu (open-source Terraform fork). Use when creating .tf files, managing cloud infrastructure, configuring providers, or designing reusable modules.

Write implementation plans with appropriate templates based on complexity. Provides minimal, standard, and comprehensive templates for different scope levels.

Guidance for solving ARC-AGI style pattern recognition tasks that involve git operations (fetching bundles, merging branches) and implementing algorithmic transformations. This skill applies when tasks require merging git branches containing different implementations of pattern-based algorithms, analyzing input-output examples to discover transformation rules, and implementing correct solutions.

This skill monitors PR CI checks by polling GitHub status until completion or timeout. Use when the user requests to check CI status, wait for CI to pass, monitor PR checks, or verify build status. Applicable for queries like "check my CI", "wait for CI to pass", "is my PR green", or "monitor CI checks".

Guidance for Bayesian MCMC sampling tasks using RStan. This skill applies when implementing hierarchical Bayesian models, configuring Stan/RStan for MCMC inference, or working with posterior distributions. Use for tasks involving Stan model specification, RStan installation, MCMC diagnostics, and Bayesian hierarchical modeling.

Guide for debugging and fixing bugs in the OCaml garbage collector, particularly memory management issues in the runtime's sweeping and allocation code. This skill applies when working on OCaml runtime C code, investigating segfaults in GC operations, or fixing pointer arithmetic bugs in memory managers with size-classed pools and run-length encoding.

Guidance for optimizing numerical linear algebra computations, particularly finding eigenvalues of small dense matrices faster than standard library implementations. This skill applies when the task involves performance optimization of matrix operations, beating numpy/scipy performance baselines, or writing high-performance numerical code with Cython/LAPACK.

Guidance for implementing high-performance portfolio optimization using Python C extensions. This skill applies when tasks require optimizing financial computations (matrix operations, covariance calculations, portfolio risk metrics) by implementing C extensions for Python. Use when performance speedup requirements exist (e.g., 1.2x or greater) and the task involves numerical computations on large datasets (thousands of assets).

Your guide to the marketing toolkit. Diagnoses where you are in your marketing journey and recommends the right skills, agents, and workflows to use next.

Guidance for configuring Nginx web servers with custom logging, rate limiting, and static content serving. This skill should be used when tasks involve setting up Nginx server blocks, configuring custom log formats, implementing rate limiting, or serving static files on specific ports.

Guidance for data resharding tasks that involve reorganizing files across directory structures with constraints on file sizes and directory contents. This skill applies when redistributing datasets, splitting large files, or reorganizing data into shards while maintaining constraints like maximum files per directory or maximum file sizes. Use when tasks involve resharding, data partitioning, or directory-constrained file reorganization.

Guidance for building pMARS (portable Memory Array Redcode Simulator) from source. This skill should be used when tasked with compiling pMARS, building Core War simulators from source packages, or creating headless/non-X11 builds of legacy C software from Debian source packages.
