Plugins

Claude Handoff to try A Claude Code plugin that generates structured handoff documents so any AI agent can pick up your work where you left off.

Added 16 May 2026

Install via /plugin marketplace add willseltzer/claude-handoff then /plugin install handoff. Run a handoff command at the end of a session to capture goal, progress, failed approaches, and resume instructions in a HANDOFF.md file. Useful when switching tools, hitting context limits, or pausing work overnight.

Includes:

  • /handoff:create — Full handoff with complete context
  • /handoff:quick — Minimal handoff, just the essentials
  • /handoff:resume — Continue from an existing handoff

Tools / IDEs

HumanLayer reference CodeLayer is an IDE built on Claude Code for orchestrating multiple agents in parallel, with keyboard-first workflows and worktree support.

Added 16 May 2026

Currently waitlist-only. Aimed at teams running fleets of agents across complex codebases. The team behind it coined 'context engineering' and publish useful frameworks worth reading independently of the product.

Includes:

  • 12 Factor Agents — Principles for building reliable LLM applications — github.com/humanlayer/12-factor-agents
  • Advanced Context Engineering (ACE-FCA) — Talk and framework for solving hard problems in complex codebases
  • AI That Works — Weekly podcast on getting the most from current models

Skills

Taste Skill to try Open-source SKILL.md files that stop AI coding agents from generating generic-looking frontends.

Added 16 May 2026

Install with npx skills add Leonxlnx/taste-skill. Works with Claude Code, Cursor, Codex, Gemini CLI, v0, Lovable, OpenCode, and AI Studio. Drop the skill files into your project and the agent picks them up automatically when generating UI.

Includes:

  • taste-skill — Default all-rounder for premium frontend output without forcing one visual style
  • gpt-tasteskill — Stricter variant for GPT and Codex models
  • image-to-code-skill — Generates design references first, then implements closely
  • redesign-skill — Visual audit and redesign pass for existing projects
  • soft-skill — Calm, expensive-looking interfaces with soft contrast and whitespace
  • output-skill — Prevents placeholders and half-finished work
  • minimalist-skill — Editorial product UI with restrained colour and sharp structure
  • brutalist-skill — Swiss typography, raw structure, sharper contrast (beta)
  • stitch-skill — Google Stitch-compatible semantic design rules
  • imagegen-frontend-web — Premium website reference image generation
  • imagegen-frontend-mobile — Mobile screen concepts and multi-screen flows
  • brandkit — Brand-kit overview images with logos, colours, mockups
Matt Pocock's Skills to try A collection of Claude Code skills from Matt Pocock targeting common AI-assisted engineering failure modes: misalignment, verbose output, broken code, and weak architecture.

Added 16 May 2026

Install with npx skills@latest add mattpocock/skills, then run /setup-matt-pocock-skills to configure issue tracking, labels, and documentation preferences per repo. Split into engineering skills — debugging, TDD, architecture, and breaking work into issues or PRDs — and productivity skills for compression, planning, and handoffs.

Includes:

  • diagnose — Systematic debugging loop for hard bugs
  • grill-with-docs — Alignment session that builds shared domain language
  • triage — Issue triage through state machines
  • improve-codebase-architecture — Identifies architectural improvements
  • setup-matt-pocock-skills — Per-repo configuration scaffold
  • tdd — Red-green-refactor test-driven development
  • to-issues — Breaks plans into independently grabbable issues
  • to-prd — Synthesises conversations into PRDs
  • zoom-out — Higher-level code context explanation
  • prototype — Throwaway prototypes for design exploration
  • caveman — Ultra-compressed communication (~75% fewer tokens)
  • grill-me — Exhaustive planning interview
  • handoff — Compact conversation summaries for handoffs
  • write-a-skill — Creates properly structured new skills
Shaping Skills to try Claude Code skills implementing the 'shaping' and 'breadboarding' methods from Basecamp's Shape Up, adapted for AI-assisted work.

Added 16 May 2026

Install by cloning into ~/.local/share/shaping-skills and symlinking each skill into ~/.claude/skills/ — skills must be direct children of that folder for discovery and updates. Document skills turn transcripts into project docs; the solo skills are experimental. Also ships a 'Ripple Check' hook that reminds Claude to update related documentation when editing shaped projects.

Includes:

  • /framing-doc — Turns conversation transcripts into framing documents
  • /kickoff-doc — Turns kickoff discussions into builder reference docs
  • /shaping — Iterates on requirements and solution together before building (experimental)
  • /breadboarding — Maps systems into UI and code affordances for vertical slices (experimental)
