minerva-rubric-feedback

A cross-platform AI plugin that gives structured feedback on rubric (HC / LO) applications in Minerva assignment PDFs or Google Docs.

For each tagged rubric it evaluates three dimensions:

• (a) Body — does the body text actually demonstrate the HC, or is the tag performative?
• (b) Footnote — Strong / Adequate / Weak, with specific reasoning
• (c) Past professor feedback — did you address what was flagged in prior assignments?

Features:

• Multi-agent discipline evaluation — AH, CS, NS, SS parallel Sonnet agents
• Grammar and typo checks — parallel Haiku agents
• Google Drive / Docs integration — read assignments by URL or title
• Cross-platform — Claude Code, Cursor, Codex, Gemini CLI

Installation

Run this in your project directory:

npx minerva-rubric-feedback

Installs all platform files automatically:

• Claude Code: .claude/skills/rubric-feedback/ + CLAUDE.md + hooks
• Cursor: .cursor/rules/rubric-feedback.mdc
• Codex: AGENTS.md
• Gemini CLI: GEMINI.md

Then install Playwright (needed to scrape past assignment feedback):

pip install playwright && playwright install chromium

Google Drive Setup

Authenticate Google Drive MCP to read assignments from Drive:

• Claude Code: /mcp → select "claude.ai Google Drive"
• Cursor: add to .cursor/mcp.json:

  {
    "mcpServers": {
      "google-drive": {
        "url": "https://drivemcp.googleapis.com/mcp/v1"
      }
    }
  }

• Codex / Gemini: configure Google Drive OAuth in your MCP client
