View and manage code-to-spec discrepancies. Detects API changes, function signature mismatches, and documentation gaps. Supports brownfield analysis and code-spec comparison.

Use when implementing features or adding functionality - dispatches incremental-tdd-agent that enforces ONE test at a time, preventing batch test writing that defeats incremental design discovery. Maintains discipline through entire feature implementation (10+ test cycles)

Use when encountering bugs, test failures, unexpected behavior, errors, or performance problems - dispatches systematic-debugging-agent that enforces 4-phase process (root cause investigation, pattern analysis, hypothesis testing, implementation) to prevent quick-fix attempts and ensure proper debugging

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Guidance for finding probability distributions that satisfy specific statistical constraints such as KL divergence targets, entropy requirements, or moment conditions. This skill should be used when tasks involve constructing discrete or continuous probability distributions with specified divergence measures, entropy values, or other distributional properties through numerical optimization.

Alpha and beta diversity analysis for microbiome data. Calculate within-sample richness, evenness, and between-sample dissimilarity with phyloseq and vegan. Use when comparing community composition across samples or testing for group differences in microbiome structure.

Simplify overly complex Django code and detect Django-specific anti-patterns. Use when user asks to simplify, refactor, or improve Django code, find N+1 queries, detect Django anti-patterns, optimize QuerySets, or analyze Django project architecture. Triggers on requests involving Django models, views, QuerySets, ORM optimization, serializers, forms, signals, middleware, or Django best practices. For general Python analysis, use the python-simplifier skill instead.

Django framework workflow guidelines. Activate when working with Django projects, manage.py, django-admin, or Django-specific patterns.

Expert on Intel 8237A DMA Controller for ES-1841. Provides guidance on DMA transfers, floppy/HDD data transfer, DRAM refresh, page registers, and channel configuration.

Captures Dmitrii's distinctive writing voice and preferences for all written outputs. Use when creating case studies, blog posts, articles, documents, emails, proposals, PRDs, specifications, messages, or any written content on Dmitrii's behalf. MUST be invoked for any mid-to-long form content creation.

Specialized skill for designing primers to insert DNA sequences into circular plasmids using Q5 site-directed mutagenesis (SDM). This skill should be used when tasks involve inserting sequences into plasmids, designing primers for Q5 SDM insertions, or converting an input plasmid to an output plasmid with additional sequence. The skill provides workflows for understanding Q5 SDM mechanics, proper primer design with annealing regions, Tm calculation, and critical verification strategies.

This skill provides guidance on finding and using D&D 5e rules for campaign content creation.

A comprehensive DnD campaign and adventure creation skill for game masters and creative content creators. Helps design complete campaigns, adventures, NPCs, encounters, maps, and storylines tailored for tabletop play. Use this when designing D&D content, creating campaign worlds, developing adventure hooks, designing encounters, or building narrative structures for player tables.
