youtube-transcript
by michalparkola
Download YouTube video transcripts when user provides a YouTube URL or asks to download/get/fetch a transcript from YouTube. Also use when user wants to transcribe or get captions/subtitles from a YouTube video.
data-sleuth
by petekp
Identify non-obvious signals, hidden patterns, and clever correlations in datasets using investigative data analysis techniques. Use when analyzing social media exports, user data, behavioral datasets, or any structured data where deeper insights are desired. Pairs with personality-profiler for enhanced signal extraction. Triggers on requests like "what patterns do you see", "find hidden signals", "correlate these datasets", "what am I missing in this data", "analyze across datasets", "find non-obvious insights", or when users want to go beyond surface-level analysis. Also use proactively when you notice interesting anomalies or correlations during any data analysis task.
checkpoint
by petekp
Meta-cognitive decision support that analyzes current context and surfaces intelligent next-step options to the user. Use this skill when: (1) User explicitly invokes /checkpoint, (2) Significant work has been completed and a checkpoint is valuable, (3) Uncertainty or ambiguity exists about requirements or approach, (4) Task complexity has expanded beyond initial scope, (5) Before finalizing or committing to ensure nothing is missed. This skill pauses execution, assesses the situation holistically, and presents 2-5 contextually-appropriate options via AskUserQuestion, with a recommended option and rationale.
dspy-output-refinement-constraints
by OmidZamani
This skill should be used when the user asks to "refine DSPy outputs", "enforce constraints", "use dspy.Refine", "select best output", "use dspy.BestOfN", mentions "output validation", "constraint checking", "multi-attempt generation", "reward function", or needs to improve output quality through iterative refinement or best-of-N selection with custom constraints.
business-case-development
by aj-geddes
Build compelling business cases to justify investments and secure funding. Quantify benefits, assess costs, manage risks, and present compelling ROI arguments to leadership.
cost-optimization
by HermeticOrmus
Optimize cloud costs through resource rightsizing, tagging strategies, reserved instances, and spending analysis. Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies.
simplify
by brianlovin
Simplify and refine recently modified code for clarity and consistency. Use after writing code to improve readability without changing functionality.
dev-experts
by DeevsDeevs
"Apply opinionated developer personas for architecture decisions, production debugging, language-specific code review, comprehensive reviewer passes, and test strategy. Use when you need an architect plan, devops investigation, Rust/Python/C++ review, grumpy reviewer audit, or tester-driven test plan. Triggers: architect, devops, rust-dev, python-dev, cpp-dev, reviewer, tester, pre-merge review, refactor for maintainability."
python-performance-optimization
by NickCrew
Python performance optimization patterns using profiling, algorithmic improvements, and acceleration techniques. Use when optimizing slow Python code, reducing memory usage, or improving application throughput and latency.
initialize-ef-core-dbcontext
by jim60105
Initialize EF Core DbContext for an ASP.NET Core project using EF Core Power Tools CLI. Use when the user wants to scaffold a database context, generate entity models from an existing database, or set up Entity Framework Core with connection strings and dependency injection.
superpowers-tdd
by anthonylee991
Applies tests-first discipline (red/green/refactor) and adds regression tests for bugs. Use when implementing features, fixing bugs, or refactoring.
git-safety-hooks
by helderberto
Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations or add git safety guardrails.
tdd
by helderberto
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants test-first development, or requests TDD workflow.
readwise-prune
by edwinhu
Clean up stale Readwise Reader documents. Use when the user wants to declutter their reading library, remove old unread articles, or manage Reader inbox. Triggers on "clean up readwise", "prune reader", "delete old articles", "declutter reading list".
dev-tdd
by edwinhu
This skill should be used when the user asks to "implement using TDD", "test-driven development", "RED-GREEN-REFACTOR", or "write failing test first". Enforces test-first approach with RED-GREEN-REFACTOR cycle and execution-based verification.
testing-tdd
by jasonraimondi
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
meta-optimize-skill-md
by jasonraimondi
Reviews and improves existing skills by auditing clarity, trigger quality, workflow completeness, and instruction density, then rewriting SKILL.md with minimal-drift improvements. Use when user asks to improve a skill, review SKILL.md, optimize skill prompts, tighten skill descriptions, or refactor skill documentation.
