vlmkit
vlmkit
mizchi / skills

Entry-point for the `@mizchi/vlmkit` toolkit — VLM-driven frontend kit covering visual regression (snapshot / diff / regression-watch), markup synthesis from screenshots, design-token / theme / a11y / i18n audits, and a 2-stage VLM + LLM CSS auto-repair loop. Use when a coding agent has edited HTML/CSS and needs to know whether the visible output changed, where it changed, and which CSS properties drove the change — or when the task is markup-from-image / token / theme audit / fix-loop driven by VLM. This skill orients you to the 5 detailed sub-skills (vrt-visual-diff / vrt-migration-eval / vrt-markup-synth / vrt-regression-watch / vrt-css-fix-loop) and the verb-group CLI; pick the matching sub-skill once the task shape is clear.

app-ai-guardrails
app-ai-guardrails
a-tokyo / agent-skills

Scaffold a new production application with the full agentic-AI guardrail canon baked in from commit #1: a uniform 7-gate interface (lint, typecheck, test, coverage, build, e2e, audit) on each stack's native runner, strict types, maximal static analysis, coverage thresholds with teeth plus seed tests, pre-commit hooks, hardened CI with optional SonarCloud, supply-chain pinning, and an agent-ready AGENTS.md — every gate verified green before the first commit. Native adapters: Next.js, NestJS, Django, Go, Rust, Spring Boot; a discovery method maps the canon to other stacks. USE FOR: creating or scaffolding a new app, service, or API from scratch; bootstrapping a greenfield repo that AI agents will build in. DO NOT USE FOR: retrofitting an existing codebase or scaffolding a new package into an existing monorepo (both assume repo-root ownership), LLM-safety or content-moderation guardrails, or adding a single tool to an existing project.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
