Enforces use of Context7 MCP for all external library documentation. Prevents API hallucination by requiring real-time doc fetching before any external library call. Auto-triggered when external library usage is detected in code context.

Reading coach: guides users through books systematically with knowledge compilation, mastery testing, spaced repetition, and knowledge querying. Triggers on "read this book", "book study", "start studying", "/book-study".

Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, or extract information from web pages.

Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.

When the user wants to audit, review, or diagnose SEO issues on their site. Also use when the user mentions "SEO audit," "technical SEO," "why am I not ranking," "SEO issues," "on-page SEO," "meta tags review," "SEO health check," "my traffic dropped," "lost rankings," "not showing up in Google," "site isn't ranking," "Google update hit me," "page speed," "core web vitals," "crawl errors," or "indexing issues." Use this even if the user just says something vague like "my SEO is bad" or "help with SEO" — start with an audit. For building pages at scale to target keywords, see programmatic-seo. For adding structured data, see schema-markup. For AI search optimization, see ai-seo.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Use this skill to migrate legacy Android camera implementations (Camera1 or raw Camera2 APIs) to CameraX. CameraX is a lifecycle-aware Jetpack library built on top of Camera2 that resolves camera rotation issues and handles device dependencies.

Learn how to install and migrate to Jetpack Navigation 3, and how to implement features and patterns such as deep links, multiple backstacks, scenes (dialogs, bottom sheets, list-detail, two-pane, supporting pane), conditional navigation (such as logged-in navigation vs anonymous), returning results from flows, integration with Hilt, ViewModel, Kotlin, and view interoperability.

Android development skill suite from Google. Use when working on Android apps, Kotlin code, Jetpack libraries, Android Gradle Plugin (AGP), Jetpack Compose UI, CameraX, Navigation component, app performance profiling, Google Play publishing, Android system APIs, or Android XR/immersive experiences. Triggers include "Android app", "Kotlin", "Jetpack Compose", "AGP migration", "CameraX", "Play Store", "Android performance", "Gradle upgrade", or any Android-specific development task.

Provides guidelines for developing projected applications for Android Display AI Glasses using the Jetpack Compose Glimmer UI toolkit. This skill covers foundational Glimmer design principles, workflows for implementing Jetpack Compose Glimmer, and interaction models for the glasses form factor. Use this skill to build an Android XR Augmented Experience application with Jetpack Compose Glimmer that adheres to the Glimmer design system for optimized Glasses styling.

Create distinctive, production-grade frontend interfaces with high design quality. Avoids generic AI aesthetics in favor of premium, modern UI.

Comprehensive performance and architecture optimization for React and Next.js. Use this for code reviews, refactoring, or building new components.

Helps users discover and install agent skills. Use this when the user asks "how do I do X", "find a skill for X", or wants to extend agent capabilities.

Senior-engineer code review: spec compliance first, then SOLID, security, performance, and code quality. Produces a structured P0-P3 severity report. Blocking issues (P0/P1) must be resolved before merge. Triggers on keyword "review" or when REVIEW workflow is active.

Structured ideation before committing to a design. Socratic questioning to surface hidden requirements and constraints. Produces 2-3 concrete approaches with explicit tradeoffs. Runs at the start of the PLAN workflow.

Chain PLAN + BUILD + REVIEW automatically. Pauses at plan for human OK.

Systematically understand an unfamiliar codebase or feature area. Outputs a populated .ohc/PROJECT.md with stack, architecture, conventions, entry points, and gotchas. Run at project start or when entering new feature territory.

PRD-loop persistence mode: iterate BUILD until verifier passes or max blocked attempts. Triggers ralph keep going keywords and /ohc-ralph. Deactivate via stop ralph.

Dispatch multiple specialized subagents to work in parallel on independent tasks using git worktrees to prevent conflicts. Use when a plan has 3+ independent tasks or total work >2h. Triggers when BUILD workflow runs a multi-task plan.

Normalize user-provided specs in any format into .ohc/doc-sources.md plus a traced plan. Triggers: from my docs, existing spec, external spec, /ohc-document-intake.

Pre-merge checklist, changelog entry, PR description, and worktree cleanup. Ensures no debug code, all tests pass, documentation updated. Triggers on keyword "ship" or when SHIP workflow is active.

Transform a goal into a precise executable task list saved to .ohc/plans/. Run before any task >30 minutes. Includes deep interview, approach selection, task decomposition with success criteria. Triggers on keyword "plan".

Ultra-compressed communication mode that removes filler while preserving technical accuracy. Use when the user explicitly asks for "caveman mode", "compressed mode", or to stay terse/compressed until told to stop.

Anti-overengineering rules. Use when writing, reviewing, or refactoring code. Enforces surgical changes, explicit assumptions, minimal scope, and verifiable success criteria. Extended from Karpathy guidelines for team AI workflows.

Post-session learning loop. Compares plan vs actual, extracts novel patterns, updates USER.md and PROJECT.md, promotes draft skills. Run after any session >30 minutes. Triggers on keyword "retro" or auto-suggested by on-stop hook.

Hypothesis-driven debugging loop. Forces explicit hypothesis formation before any fix attempt. Prevents guess-and-check debugging. Use when investigating or fixing an observed bug, failing test, runtime error, broken behavior, or performance regression.

RED-GREEN-REFACTOR discipline. Write failing test first, minimum code to pass, then refactor. Enforces verifier check before claiming any task done. Triggers on keyword "tdd" or when BUILD workflow is active.

Meta-skill for creating new skills in oh-my-colab format. Use when RETRO identifies a pattern worth formalizing. Ensures correct folder structure, 200-line discipline, proper frontmatter, and token-efficient design.
