v2.2.0: Core + First-Run Install Wizard + antislop-ui skill

What's new in v2.2.0

antislop is now a system: a lean, always-loaded core (antislop.md) plus optional additive skills, one per concern, shipping one per version.

First-Run Install Wizard (in the core)

• New install flow: download antislop.md once, tell your agent to read it, and the agent walks you through choosing skills, downloading them, and setting up the pointer for you.
• An offer, not a requirement: antislop.md alone remains a complete filter.
• The wizard asks which skills to install (multi-select, "All" recommended), downloads the chosen files into the same folder as the core, appends a managed pointer block at the end of your entry file (AGENTS.md / CLAUDE.md / GEMINI.md / etc.) without touching existing content, and asks the usage-mode question.
• Honest direction handling: if no DESIGN.md exists, antislop recommends having one and offers three paths (user-supplied direction, agent-supplied with a warning, or skip with the "draft without direction" label).

New skill: antislop-ui (UI / visual)

• Deep-dives the UI/visual concern: color, layout, components, decoration, structural flow, and motion. 28 patterns in the tell-why-fix shape, each citing the governing core rule (R-XX), plus a UI Skill Checklist that runs alongside the core Delivery Gate.
• Additive, never duplicated: references core rules by number and loads with the core, never instead of it.

Docs

• README rewritten as the system index with the new install instructions.
• ROADMAP updated: v2.2.0 marked done; antislop-copywriting is next (v2.3.0).

Backward compatible

• Existing single-file users keep a complete filter.
• Existing manual pointers are merged, not duplicated.
