Enforce strict code quality conventions across Python, TypeScript, and Go codebases — naming precision, casing rules, import discipline, declaration ordering, symmetry, dead code elimination, and magic value refactoring. Audit repositories or files for violations and generate fix reports.
npx claudepluginhub oborchers/fractional-cto --plugin pedantic-coderScan all CLAUDE.md files in the repository and check code for compliance with project-specific guidelines
Audit an entire repository for pedantic violations — systematically scans the codebase for naming, casing, symmetry, ordering, consistency, and structural issues
Review the current code for pedantic violations — naming, casing, symmetry, ordering, consistency, dead code, and every small detail that matters
This skill should be used when the user is abbreviating identifiers, using acronyms, or when a codebase has inconsistent short forms like btn/button, msg/message, req/request. Covers the abbreviation decision framework, approved short forms, and the rule that consistency beats brevity.
This skill should be used when the user is naming boolean variables, writing predicate functions, using flags or toggles, or when code contains ambiguous boolean names like flag, status, check, active without proper prefixes. Covers is/has/can/should prefixes, positive naming, and the rule that a boolean's name must read as a true/false question.
This skill should be used when the user is writing code with mixed casing conventions, choosing casing for identifiers, enforcing casing consistency across a codebase, or when camelCase and snake_case appear in the same file. Covers per-context casing rules, acronym handling, and the absolute prohibition of mixed conventions.
This skill should be used when the user's code contains commented-out code blocks, unused imports, unreachable branches, TODO/FIXME comments that have been sitting for more than a day, or comments referencing removed functionality. Covers the elimination of dead code and the rule that version control remembers so you don't have to.
This skill should be used when the user is organizing code within a file, ordering class members, structuring module exports, or when a file has constants mixed with functions mixed with classes in no predictable order. Covers file-level ordering, class member ordering, and the rule that every file should have the same shape.

Enhances code agents with Go best practices covering performance, modern syntax, generics, patterns, testing, error handling, and concurrency.
Full-spectrum design patterns skill: Detect anti-patterns, diagnose architectural debt, and generate production-ready refactored code. Covers GoF, SOLID, Clean Architecture, DDD, CQRS, Microservices, and Cloud patterns.
Mindful AI coding framework — discipline over cleverness. Skill + 21 slash commands + 8 specialist agents + 5 runtime hooks + 15 default checklists + Master Orchestrator + Gravity hub. Works on any model tier (Opus/Sonnet/Haiku). Integrates Claude Design for visual work.
Comprehensive code formatting plugin with Prettier integration. Use when you need to format code, validate formatting, or maintain consistent code style. Activates with phrases like 'format my code', 'check formatting', or 'apply code style'. Supports JavaScript, TypeScript, JSON, CSS, Markdown, and many other file types with automatic formatting on file operations.
Organize, sort, and clean import statements
This skill should be used when the model needs to ensure code quality through comprehensive linting and formatting. It provides automatic linting workflows for orchestrators (format → lint → resolve via concurrent agents) and sub-agents (lint touched files before task completion). Prevents claiming "production ready" code without verification. Includes linting rules knowledge base for ruff, mypy, and bandit, plus the linting-root-cause-resolver agent for systematic issue resolution.
Research-backed best practices for building modern, production-grade Python packages — project structure, pyproject.toml, typing, testing, CI/CD, documentation, versioning, API design, packaging, security, and developer experience
Transforms Claude Code conversation transcripts into polished, first-person blog posts through an interactive 5-stage pipeline — parse, triage, outline, draft, polish — with human editorial gates at every stage
Structured thinking methods that counteract LLM reasoning biases during problem exploration — first principles, inversion, constraint manipulation, perspective forcing, analogy search, and more, with user-gated parallel subagent exploration for deep dives
Research-backed, opinionated guidance for designing world-class RESTful APIs — routes, naming, errors, auth, caching, webhooks, and more, distilled from Stripe, GitHub, Twilio, Shopify, Google, and Microsoft
Research-backed visual design principles for websites, presentations, documents, and any visual medium — grounded in VisAWI, Gestalt psychology, and empirical aesthetics research

Generic AI gives you suggestions. fractional-cto gives you standards.
Each skill encodes a proven engineering principle (naming precision, API design patterns, cloud governance) and enforces it the moment Claude detects relevant work. You get the rigor of Stripe's API design, Nielsen Norman's usability research, and production cloud architecture baked into every session. No bookshelf required.
The skills are deliberately opinionated. They don't present five options and ask you to choose. They tell you what to do, cite why, and show you the code. If you disagree, edit the skill. It's just markdown.
Every plugin activates the moment your Claude session starts. A session hook fires, reads the plugin's skill index, and injects it into context. From that point on, Claude knows what principles exist and when to apply them.

Each plugin carries review checklists, good/bad pattern comparisons, working code examples, and a dedicated reviewer agent for deeper audits.
