Guidance for optimizing numerical linear algebra computations, particularly finding eigenvalues of small dense matrices faster than standard library implementations. This skill applies when the task involves performance optimization of matrix operations, beating numpy/scipy performance baselines, or writing high-performance numerical code with Cython/LAPACK.

This skill provides guidance for creating polyglot files that are valid in both C and Python. It should be used when tasks require writing code that compiles and runs correctly as both a C program and a Python script, producing identical or specified output from each interpreter/compiler.

Generate or update component documentation with usage examples, props tables, and Storybook stories. Use when documenting new components or improving existing component docs.

Locate and retrieve specific documentation sections from DiPeO's docs/ by heading anchors or keywords. Returns minimal, targeted excerpts instead of full files. Use when you need precise documentation context without loading entire guides.

Guidance for SQL query optimization tasks. This skill should be used when optimizing slow SQL queries, improving database performance, or rewriting queries to be more efficient. Covers query plan analysis, benchmarking strategies, and database-specific optimization techniques.

Codify your brand's writing style into a reusable voice guide. Analyzes existing content to extract patterns, then generates a comprehensive style document for consistent messaging across all channels.

Skill on how to write a task. Use when user asks you to write a task (for Asana, Linear, Jira, Notion and equivalent). Also activates when user says "create task", "write task", or similar task creation workflow requests.

This skill guides writing of new Ruby code following modern Ruby 3.x syntax, Sandi Metz's 4 Rules for Developers, and idiomatic Ruby best practices. Use when creating new Ruby files, writing Ruby methods, or refactoring Ruby code to ensure adherence to clarity, simplicity, and maintainability standards.

This skill provides guidance for creating CoreWars warriors that achieve target win rates against multiple opponents. Use this skill when tasked with writing Redcode warriors, optimizing CoreWars strategies, or achieving specific win rate thresholds against a set of opponents. The skill covers systematic opponent analysis, parameter tuning methodologies, and common pitfalls in warrior design.

Update and maintain documentation to reflect current implementation after code changes, refactoring, or new features. Remove temporal language, verify accuracy against code, and keep docs current. Use when updating docs, syncing documentation, removing outdated info, or after implementing features.

Test implementation of thin router skill for DiPeO backend. Provides decision criteria and documentation anchors for FastAPI server, CLI (dipeo run/results/metrics/compile/export), SQLite schema, and MCP integration in apps/server/. Use when task mentions CLI commands, server endpoints, database queries, or MCP tools.

Use when creating new skills, editing existing skills, or verifying skills work - applies TDD to documentation by testing with subagents before writing

Top orchestrator for complete doc system. Delegates to ln-110 coordinator (project docs via 5 L3 workers) + ln-120-150 workers. Phase 4: global cleanup. Idempotent.

Create category-aware, AEO-optimized blog posts for Lightfast. Use when writing technology deep-dives, company announcements, or product launches.

Guidance for creating polyglot files that are valid in both Python and C. This skill applies when tasked with writing code that must be parseable and executable by both the Python interpreter and C compiler. Covers polyglot syntax techniques, testing strategies, and critical cleanup requirements.

Research best practices via MCP Ref/Context7 and create documentation (guide/manual/ADR). Single research, multiple output types.

This skill guides writing comprehensive Minitest tests for Ruby and Rails applications. Use when creating test files, writing test cases, or testing new features. Covers both traditional and spec styles, fixtures, mocking, and Rails integration testing patterns.

Router skill for DiPeO frontend (React, visual editor, GraphQL integration, TypeScript types). Use when task mentions React components, diagram editor, GraphQL hooks, or type errors. For simple tasks, handle directly; for complex work, escalate to dipeo-frontend-dev agent.

Write Ruby and Rails code in DHH's distinctive 37signals style. Use this skill when writing Ruby code, Rails applications, creating models, controllers, or any Ruby file. Triggers on Ruby/Rails code generation, refactoring requests, or when the user mentions DHH, 37signals, Basecamp, HEY, Fizzy, or Campfire style.

Guidance for implementing encoders/compressors that must produce output compatible with an existing decoder/decompressor. This skill applies when tasked with writing compression algorithms, arithmetic coders, entropy encoders, or any encoder that must be the inverse of a given decoder implementation.
