Guidance for implementing path tracers and ray tracers to reconstruct or generate images. This skill applies when tasks involve writing C/C++ ray tracing code, reconstructing images from reference images, or building rendering systems with spheres, shadows, and procedural textures. Use for image reconstruction tasks requiring similarity matching.

Provides systematic approaches for solving constraint-based scheduling problems, such as finding meeting times that satisfy multiple participant availability windows, preferences, and existing calendar conflicts. This skill should be used when tasks involve scheduling with constraints, calendar conflict resolution, time slot optimization, or finding valid time windows across multiple inputs with hard and soft constraints.

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.

Generate Product Requirements Document (PRD) through interactive Q&A.Use when: clarifying feature requirements, defining user stories, establishing acceptance criteria, starting a new feature.Keywords: PRD, product requirements, requirements document, feature requirements, user stories, acceptance criteria.This is the first step of the spec-driven development workflow (or second if research was done first).

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.

This skill provides guidance for extracting secrets from vulnerable executables. It should be used when tasks involve binary analysis, reverse engineering executables to find hidden flags/secrets, or exploiting buffer overflows and other vulnerabilities to extract protected data. Applicable to CTF challenges, security research, and authorized penetration testing scenarios.

This skill should be used when organizing and structuring Personal Knowledge Management (PKM) vaults, particularly Obsidian vaults using the Linking Your Thinking (LYT) methodology. Use this skill when the user asks to analyze notes, create MOCs (Maps of Content), find related notes, organize folders, generate Index.md files, or improve vault structure. This skill provides Python scripts for vault analysis, link finding, and MOC generation, along with LYT methodology references and templates.

Coordinates 9 specialized audit workers (security, build, architecture, code quality, dependencies, dead code, observability, concurrency, lifecycle). Researches best practices, delegates parallel audits, aggregates results into single Linear task in Epic 0.

This skill provides guidance for fixing LaTeX overfull hbox warnings by making synonym substitutions. It should be used when the task involves resolving LaTeX line-breaking issues by replacing words with synonyms from an allowed list, particularly when the goal is to reduce line width without changing meaning.

Apple firmware and binary reverse engineering with the ipsw CLI tool. Use when analyzing iOS/macOS binaries, disassembling functions in dyld_shared_cache, dumping Objective-C headers from private frameworks, downloading IPSWs or kernelcaches, extracting entitlements, analyzing Mach-O files, or researching Apple security. Triggers on requests involving Apple RE, iOS internals, kernel analysis, KEXT extraction, or vulnerability research on Apple platforms.

Research and analysis skill for in-depth technical investigation.Use when: analyzing technical problems, exploring solutions, investigating issues, comparing technologies, understanding root causes.Keywords: research, analyze, investigate, technical problem, comparison, evaluation, deep dive, root cause analysis.This is the optional first step of the spec-driven development workflow, before create-prd.
