Installation Playbook

Fresh Setup (one shot)

The repo ships an install script that adds every marketplace and plugin in one go. Use this on a new machine:

./scripts/install-all.sh              # Tier 1 + 2 + 3
./scripts/install-all.sh --all        # include Tier 4
./scripts/install-all.sh --tier 1     # core only
./scripts/install-all.sh --dry-run    # preview without changes

It is idempotent — already-installed marketplaces and plugins are skipped.

Manual Setup (per-plugin)

# 1. Add marketplaces
claude plugin marketplace add yieon-lyon/lyon-skills
claude plugin marketplace add forrestchang/andrej-karpathy-skills
claude plugin marketplace add hashicorp/agent-skills
claude plugin marketplace add grafana/skills
claude plugin marketplace add whchoi98/aws-skills-for-claude-code

# 2. Install core plugins
claude plugin install lyon@lyon-skills
claude plugin install andrej-karpathy-skills@karpathy-skills

# 3. Install IaC plugins
claude plugin install terraform-code-generation@hashicorp
claude plugin install terraform-module-generation@hashicorp

# 4. Install observability plugins
claude plugin install grafana-lgtm@grafana-skills
claude plugin install grafana-core@grafana-skills

Update All

# Check for updates
claude plugin marketplace update

# Reinstall to get latest
claude plugin install {plugin}@{marketplace} --force

Marketplace Architecture

Each marketplace follows the Agent Skills standard:

├── .cursor-plugin/marketplace.json   # Cursor manifest (identical)
├── .agents-plugin/marketplace.json   # Codex manifest (identical)
├── skills/
│   └── {skill-name}/
│       ├── SKILL.md                  # Skill definition (frontmatter + body)
│       ├── references/               # On-demand reference docs
│       ├── scripts/                  # Executable helpers
│       └── assets/                   # Templates, schemas
└── skill-registry.json               # Optional flat index

SKILL.md Frontmatter Fields

Field	Required	Description

Adding a New Skill Source

When evaluating a new skill marketplace:

1. Check structure: Must have .claude-plugin/marketplace.json
2. Verify SKILL.md: Frontmatter with name and description fields
3. Test locally: claude plugin marketplace add {owner}/{repo} then preview
4. Review content: Skills should be concise (<500 lines), domain-specific
5. Update catalog: Add to the appropriate tier in this file
