Mark plugin for Claude Code
Ask an agent to plan your week from scratch and you get a different plan each time. The mark plugin gives Claude Code the Mark MCP connection and Mark's skills, short playbooks for jobs like planning a week of posts, so the agent follows the same steps each run.
Connecting an agent needs a Mark workspace. Mark is waitlist-only: self-serve signup is not open yet.
Install it
In Claude Code, add the marketplace and install the plugin.
claude plugin marketplace add Life-With-Data/mark-agent-pluginclaude plugin install mark@mark-gtmRun /mcp, select mark, and choose Authenticate. Sign in to Mark and pick the workspace.
What the plugin adds
A skill is a playbook the agent follows for one job. Skills call the same tools as any other request, so they do not skip review.
/mark:plan-week
Draft the week's posts from your pillars and the calendar.
/mark:draft
Draft a post or page for one channel with your brand's rules and Mark's checks, then save it for review.
/mark:review
Show posts waiting on you and what blocks approval, then act only on your choice.
/mark:performance-review
Read search and content results, then propose changes without saving them.
/mark:ai-visibility
See how AI assistants talk about you and draft FAQ answers.
/mark:site-fixes
Read the site audit and readiness. Mark never edits the site.
/mark:keyword-ideas
Research keywords, shortlist them, and save a brief as a draft.
/mark:brand-interview
Set up brand voice, phrases to avoid and claims from your files and a short interview, saving each only after you approve it.
Where it works
The plugin works in Claude Code, Cursor, Grok Bot, Codex, and VS Code through Agent Plugins. In ChatGPT, Windsurf or Grok, connect the MCP server instead, and add the skills if your agent reads skill folders.
More than one workspace
The plugin carries one connection, so it works in one workspace. If you work in several, install the skills on their own and add one MCP connection per workspace.

What does the Mark plugin add?
The Mark MCP connection and Mark's skills in one install. Skills show up as /mark:plan-week, /mark:draft and the rest.
Do I need a Mark account?
Yes. Skills need a Mark MCP connection, and the connection needs a Mark workspace. Mark is waitlist-only right now.
Do skills publish posts?
No. Skills save drafts for review, and by default a person approves before anything publishes. The review skill acts only on the choice you make.
Where is the source?
The plugin and skills are public on GitHub at Life-With-Data/mark-agent-plugin.
