Multi-platform installation guide for GrepAI. Use this skill when installing GrepAI on macOS, Linux, or Windows.
Helps users discover and apply shared coding solutions when they ask "has anyone solved this", "search for a fix", "find a workaround", or want proven patterns before debugging from scratch. Uses `npx shareful-ai search` to find relevant shares, compare options, and recommend the best match.
Guides setup of a shareful.ai shares repository. Runs npx shareful-ai init to create the directory structure, explains the repo layout, and walks through next steps. Use when the user wants to "set up shareful", "create a shares repo", "start sharing solutions", or "initialize shareful".
PostgreSQL database design, migration, and performance optimization best practices. This skill should be used when writing, reviewing, or refactoring database schemas, migrations, or query patterns. Triggers on tasks involving PostgreSQL databases, schema design, migration optimization, or data modeling.
Rust best practices and code quality guidelines for writing idiomatic, safe, and performant Rust code. This skill should be used when writing, reviewing, or refactoring Rust code. Triggers on tasks involving Rust programming, code review, error handling, type safety, or performance optimization.
Fundamental design principles based on Don Norman's "The Design of Everyday Things". Use when you need to: (1) design affordances and signifiers into interfaces, (2) analyze why products are confusing, (3) apply constraints to prevent errors, (4) design clear feedback mechanisms, (5) bridge gulfs of execution and evaluation, (6) create intuitive conceptual models, (7) apply human-centered design, (8) understand why users make errors and design fault-tolerant systems.
This skill provides guidance for implementing headless terminal interfaces that programmatically control shell sessions. Use this skill when implementing terminal emulation, pseudo-terminal wrappers, or interfaces like BaseTerminal that require sending keystrokes and reading output from shell processes.
Guidance for processing financial documents (invoices, receipts, statements) with OCR and text extraction. This skill should be used when tasks involve extracting data from financial PDFs or images, generating summaries (CSV/JSON), or moving/organizing processed documents. Emphasizes data safety practices to prevent catastrophic data loss.
Behavior design framework based on BJ Fogg's "Tiny Habits". Use when you need to: (1) diagnose why users aren't completing key actions, (2) reduce friction using the Ability Chain, (3) design effective prompts, (4) create tiny behaviors that compound into retention, (5) audit motivation-ability mismatches, (6) design onboarding that builds lasting habits, (7) apply B=MAP to improve activation and retention metrics.
Manage software complexity through deep modules, information hiding, and strategic programming. Use when the user mentions "module design", "API too complex", "shallow class", "complexity budget", or "strategic vs tactical". Covers deep vs shallow modules, red flags for complexity, and comments as design documentation. For code quality, see clean-code. For boundaries, see clean-architecture.
Build production-ready systems with stability patterns: circuit breakers, bulkheads, timeouts, and retry logic. Use when the user mentions "production outage", "circuit breaker", "timeout strategy", "deployment pipeline", or "chaos engineering". Covers capacity planning, health checks, and anti-fragility patterns. For data systems, see ddia-systems. For system architecture, see system-design.
Talk to customers without leading them using Mom Test rules: discuss their life not your idea, ask about specifics in the past, and talk less. Use when the user mentions "customer interviews", "validate my idea", "users say they want it but don't buy", "leading questions", or "The Mom Test". Covers commitment and advancement, avoiding compliments, and extracting signal from noise. For product-market fit, see jobs-to-be-done. For rapid prototype testing, see design-sprint.
