Configure rate limiting, manage auth secrets, set up CSRF protection, define trusted origins, secure sessions and cookies, encrypt OAuth tokens, track IP addresses, and implement audit logging for Better Auth. Use when users need to secure their auth setup, prevent brute force attacks, or harden a Better Auth deployment.
Create, critique, or revise prompts for Claude Design and similar AI UI prototype generators. Use when the user wants a visual UI prototype prompt, wants to improve an existing design prompt, shares a generated design for review, or needs prompts that preserve product semantics, domain rules, workflow state, and negative constraints instead of producing generic UI.
Write engineering design documents for architecture, API, framework, or product-contract decisions before implementation planning. Use when the user asks for a design doc, proposal, RFC-style design, contract design, or wants to debate system shape. Not for execution plans, milestone checklists, progress trackers, or implementation task breakdowns.
Write requested implementation plans, milestone checklists, execution trackers, and handoff plans from an accepted design or exact implementation direction. Use for planning artifacts only, not for ordinary implementation requests or design debate.
This skill should be used when the user asks to "review file organization", "check code layout", "identify layout smells", "audit folder structure", "review module organization", "check file naming", "find code structure issues", "review how code is organized", or mentions that AI-generated code is disorganized or hard to navigate. Works with Python and TypeScript codebases.
Share skills and top-level instructions across coding agents (Claude Code and others) via symlinks. Use for "set up multi-agent", "share skills between agents", "link AGENTS.md to CLAUDE.md", "unify agent configs", or pointing `.agents/skills` and `.claude/skills` at the same place. Auto-detects which side (`.agents/`+`AGENTS.md` or `.claude/`+`CLAUDE.md`) already has content and makes the other a symlink into it; defaults to `.agents/` canonical when starting fresh.
Set up Python quality gates (ruff lint/format, type checking, pytest + coverage, complexity, dead code, duplicates, file length) in any Python repo, wired through `prek` (pre-commit reimagined) with a `check.sh` orchestrator underneath. This skill should be used when the user says "add quality gates", "set up linting", "add python checks", "quality gate setup", "add prek", "add check script", "enforce code quality", or wants to establish code quality infrastructure in a Python project.
AlphaTab music notation in JS/TS apps. Use for @coderline/alphatab setup, Vite worker integration, fonts/soundfonts, playback controls, track rendering, AlphaTex, drum notation, and React integration.
