Marmite 0.3.2 Release Notes

We're excited to announce Marmite 0.3.2! This release introduces embedded AI agent skills, native AT Protocol publishing via standard.site, and the Marmite Playground - an interactive web app for trying marmite in the browser.

New Features

Embedded AI Agent Skills

Marmite now ships with a comprehensive Agent Skill embedded directly in the binary. The skill follows the open agent-skills format, making marmite projects instantly usable by AI coding agents like Claude Code, Codex, Gemini CLI, Cursor, and others. (#438)

The embedded skill contains a main SKILL.md with workflow-based documentation and 10 reference files covering every aspect of marmite - from CLI flags and configuration to templates, shortcodes, and deployment guides.

New CLI flags:

  • marmite --skill - Print the embedded SKILL.md to stdout
  • marmite --skill-install - Install the skill into .agents/skills/marmite/ (standard agent-skills location)
  • marmite --skill-install-claude - Install the skill into .claude/skills/marmite/ (Claude Code convention)
$ cd myproject
$ marmite --skill-install --skill-install-claude

The skill files are compiled into the binary at build time using rust_embed, so they are always available offline and always match the installed marmite version. With the skill installed, an AI coding agent has full context to create sites, add content, configure templates, set up deployment, and more.

Getting started: After installing or upgrading marmite, run the following in your project directory:

cd myproject
marmite --skill-install --skill-install-claude

That's it. Your project is now AI-agent-ready.

AT Protocol & standard.site Integration

Marmite now supports native integration with the AT Protocol and the standard.site specification. This allows you to publish your blog posts to the decentralized social web (e.g., discoverable inside Bluesky) while keeping your Marmite site as the canonical source. (#448)

This feature is fully optional and opt-in. Key capabilities:

  • Authentication - Resolves your handle via DNS or .well-known endpoints, finds your PDS using the PLC directory, and authenticates with an app password
  • Publishing - Publishes posts as site.standard.document records to your PDS, with change detection to only push new or modified content
  • Verification - Automatically generates /.well-known/site.standard.publication and injects <link> tags for publication and document discovery
  • Dry-run support - Preview what would be published without making changes (--dry-run)

Configuration in marmite.yaml:

atproto:
  handle: "myhandle.bsky.social"
  publication_uri: "at://did:plc:.../site.standard.publication/..."
  publish_content: true

See the AT Protocol standard.site documentation for setup and usage details.

Thanks to Eduardo Cuducos for this contribution!

Marmite Playground

A new interactive web application that lets you try Marmite directly in the browser without installing anything. The playground supports live editing of content and configuration, auto-complete, and auto-navigation between pages. (#359)

Try it at play.marmite.blog. The playground is a separate application in the playground/ directory, deployable via Docker.

CLI Changes

Optional Input Folder for Skill Commands

The --skill, --skill-install, and --skill-install-claude flags do not require an input folder argument. They work like --version and --help - just run them from anywhere.

For all other commands, the input folder remains required and behaves exactly as before.

AT Protocol Subcommands

Two new subcommands for AT Protocol publishing:

  • marmite <folder> auth - Authenticate with your atproto PDS using an app password
  • marmite <folder> publish - Publish posts to your PDS as site.standard.document records

The publish subcommand supports --force (re-publish all posts, ignoring change detection) and --dry-run / -n (preview what would be published without making changes).

Breaking Changes

None in this release.

Fixes

  • Fixed Chinese/CJK character tags generating duplicate entries - Non-ASCII tags (Chinese, Japanese, Korean, etc.) appeared twice in tag lists because the backward-compatibility layer stored tags under both slugified and original keys, and the Group Tera function iterated over all entries without filtering. Fixed by filtering backward-compat duplicates in the Group function and recovering original tag names for display. Also centralized all slugify calls through a new wrapper module with a Unicode fallback for scripts the slug crate cannot transliterate, and overrode Tera's built-in slugify filter for consistency. (#449, #452)
  • Fixed playground resize handle - The resize handle in the Marmite Playground was not working correctly. (#359)
  • Fixed playground responsive layout - Improved responsive behavior for the playground on smaller screens. (#359)
  • Fixed clippy pedantic warnings in atproto module - Cleaned up code quality warnings in the AT Protocol module. (#453)

Dependency Updates

  • arborium 2.16.0 -> 2.18.0 (pinned to =2.18.0; 2.18.1 has a C scanner bug that breaks zig cross-compilation)
  • chrono 0.4.44 -> 0.4.45
  • frontmatter-gen 0.0.5 -> 0.0.6
  • log 0.4.29 -> 0.4.33
  • regex 1.12.3 -> 1.12.4
  • rss 2.0.12 -> 2.0.13
  • serde_json 1.0.149 -> 1.0.150

New dependencies for AT Protocol support: ureq (with JSON feature), shrike, sha2, dirs.
