Description

Adds the enchantments collection, published at ghcr.io/jartan-llc/enchantments: Dev container Features for reproducible development environments. Each has scenario tests in CI, and pins and digest-checks what it downloads.

• claude-code: Claude Code, with its login and settings in a volume that survives rebuilds.
• container-env: per-device environment variables, kept in a volume and exported into login shells and VS Code, so no repo holds them.
• gh-config: the GitHub CLI's login, kept in a volume across rebuilds.
• grimoire: Claude Code plugins from the grimoire marketplace, for each clone.
• liza, liza-toolchain: Liza's rules and multi-agent workflow, and its agent tools (code indexes, code search).
• codebase-memory-mcp: a code graph, registered as an MCP server.

Collection checklist

• Collection name
• Maintainer name
• Maintainer contact link (i.e. link to a GitHub repo, email)
• Repository URL
• OCI Reference (must be the collection root, e.g. ghcr.io/<owner>/<repo> — one entry per repository, not one per Feature; do not include http:// or https://)
• I acknowledge that this collection provides new functionality, distinct from the existing collections part of this index.
