Guidance for fixing LaTeX overfull hbox warnings by replacing words with shorter synonyms from an allowed list. This skill applies when tasks involve modifying LaTeX documents to eliminate typographic warnings while adhering to strict word replacement constraints. Use when dealing with synonym-constrained text editing in LaTeX or similar markup languages.

This skill provides guidance for implementing headless terminal interfaces that programmatically control shell sessions. Use this skill when implementing terminal emulation, pseudo-terminal wrappers, or interfaces like BaseTerminal that require sending keystrokes and reading output from shell processes.

Guide for implementing MIPS CPU interpreters/emulators, particularly for running compiled MIPS ELF binaries. This skill applies when building virtual machines to execute MIPS32 code, creating emulators for retro game ports (like Doom), or implementing CPU simulators. Use for tasks involving ELF parsing, instruction decoding, syscall emulation, and memory management for MIPS architecture.

Guidance for installing and running Windows 3.11 in QEMU with VNC access and web-based noVNC interface. This skill should be used when tasks involve setting up legacy Windows 3.11 environments, configuring QEMU for DOS/Windows 3.x, or creating virtualized retro computing setups with remote access capabilities.

Generate hierarchical AGENTS.md structure for codebases to optimize AI agent token usage. Use when creating AGENTS.md files, documenting codebase structure, setting up agent guidance, organizing project documentation for AI tools, implementing JIT indexing, or working with monorepos that need lightweight root guidance with detailed sub-folder documentation. Covers repository analysis, root AGENTS.md generation, sub-folder AGENTS.md creation, and token-efficient documentation patterns.

Use when creating or developing anything, before writing code - refines rough ideas into bd epics with immutable requirements

Guidance for text embedding retrieval tasks using sentence transformers or similar embedding models. This skill should be used when the task involves loading documents, encoding text with embedding models, computing similarity scores (cosine similarity), and retrieving/ranking documents based on semantic similarity to a query. Applies to MTEB benchmark tasks, document retrieval, semantic search, and text similarity ranking.

Use to execute bd tasks iteratively - executes one task, reviews learnings, creates/refines next task, then STOPS for user review before continuing

Apply first-principles thinking to break down complex problems into fundamental truths and rebuild solutions from the ground up. Use when solving strategic decisions, breaking through blockers, or challenging assumptions. Triggers on first principles, Elon Musk methodology, fundamental truths, strip assumptions, physics of the problem, rebuild from scratch.

Guidance for extracting secrets from protected or obfuscated binaries through systematic static and dynamic analysis. This skill should be used when tasks involve reverse engineering executables, extracting hidden flags or keys, analyzing binary protections, or decoding obfuscated data within compiled programs.

Create distinctive, production-grade frontend interfaces with high design quality. Use when building web components, pages, or applications. Includes framework-specific guidance for Tailwind, React, Vue, and Rails/Hotwire ecosystems.

Guidance for building and installing Cython extension packages, particularly when resolving compatibility issues with modern Python and NumPy versions. This skill applies when installing legacy Cython packages, fixing NumPy 2.0 deprecation errors, resolving Python 3.x compatibility issues in extension modules, or troubleshooting Cython compilation failures. Use this skill for tasks involving setup.py with Cython extensions, deprecated NumPy type errors, or installing packages to system Python environments.

Guidance for sanitizing git repositories by identifying and removing sensitive credentials, API keys, tokens, and other secrets. This skill should be used when tasks involve cleaning repositories of secrets, preparing code for public release, auditing for credential exposure, or removing sensitive data from version control history.

Test klaude-code interactively using tmux with synchronous task completion. Use when testing UI features, verifying changes, or debugging interactive behavior. Eliminates polling/sleep by using KLAUDE_TEST_SIGNAL for precise synchronization.

Provides systematic approaches for solving multi-person scheduling problems with complex constraints. This skill should be used when finding meeting times, scheduling events, or solving optimization problems involving multiple calendars, availability windows, time-based constraints, preferences, and buffer requirements.

Guidance for setting up Git-based web deployment systems where pushing to a Git repository automatically deploys content to a web server. This skill should be used when tasks involve configuring bare Git repositories with post-receive hooks for automated web deployment, setting up lightweight web servers to serve deployed content, or creating Git-push-to-deploy workflows. Covers service persistence, permission management, and verification strategies.

This skill guides writing Ansible playbooks for server configuration. Use when hardening servers, installing packages, or automating post-provisioning tasks that cloud-init cannot handle.

Native HTML dialog patterns for Rails with Turbo and Stimulus. Use when building modals, confirmations, alerts, or any overlay UI. Triggers on modal, dialog, popup, confirmation, alert, or toast patterns.

Research and compile effective organic traffic and customer acquisition methods for new websites with zero ad spend. Includes traffic sources, community strategies, cold outreach scripts, and 30-day action plans with success stories.

This skill guides writing comprehensive RSpec tests for Ruby and Rails applications. Use when creating spec files, writing test cases, or testing new features. Covers RSpec syntax, describe/context organization, subject/let patterns, fixtures, mocking with allow/expect, and shoulda matchers.
