What Changed: Claude Code in 2026

Anthropic shipped several features since plugins launched in October 2025 that change how developers extend Claude Code:

• Agent Skills (SKILL.md) replaced static plugins as the primary extension point. Skills auto-activate based on conversation context — no slash commands needed. This repo now contains 1,900+ validated skills across 22 categories.
• ${CLAUDE_SKILL_DIR} is the official path variable for referencing files within a skill directory. It replaced the deprecated {baseDir} syntax. All 1,900+ skills in this repo use the current variable.
• Progressive Disclosure Architecture (PDA) keeps skill files concise (target: 150 lines) and offloads detailed references to a references/ subdirectory. Our 100-point grading rubric enforces this.
• Tool permissions (allowed-tools frontmatter) give each skill fine-grained access control. Scoped patterns like Bash(git:*) limit what system commands a skill can run.
• New frontmatter fields: context: fork (run in subagent), agent (subagent type), user-invocable (hide from slash menu), argument-hint (autocomplete), hooks (lifecycle events), and compatibility (AgentSkills.io standard for environment requirements).
• Claude 4.5/4.6 model family — Opus 4.6, Sonnet 4.6, Haiku 4.5 are the current models. Skills can specify model: sonnet or model: opus in frontmatter.

This README reflects the current state of the ecosystem as of March 2026.
