```

• ebb-ai - Defers any "do it later" / "by tomorrow" / "overnight" task to the cleanest electricity-grid hour inside a deadline. 40-70% lower CO2 per task, 50% cheaper via Anthropic/OpenAI Batch APIs. 9 MCP tools, per-task carbon receipts, Apache-2.0. By @Vitalini ```

Why this fits

ebb-ai ships a Claude Code plugin with a bundled SKILL.md (skills/ebb-ai/SKILL.md) — the auto-invocation skill that tells Claude when to defer a task. The plugin marketplace install (/plugin marketplace add Vitalini/ebb-ai → /plugin install ebb-ai) is one line.

Real use case: any deferrable LLM workflow — overnight summaries, batch evaluations, scheduled compliance scans, document processing. When the user says "do this later" or "by tomorrow", the skill routes the task through /ebb-ai:defer instead of dispatching synchronously, and the MCP server picks the cleanest electricity-grid hour inside the deadline.

Project facts

• Apache-2.0
• 204 passing tests (TypeScript + Python ports)
• Ships an MCP server, a Claude Code plugin, and a native OpenClaw plugin from the same monorepo
• Real grid feeds: UK National Grid ESO (key-less), US EIA, ENTSO-E, Electricity Maps
• Live demo: https://www.ebb-ai.com
• Source: https://github.com/Vitalini/ebb-ai

Checklist

• Real use case (not theoretical) — public Show-HN-ready release at v0.8.2
• Well-documented (https://www.ebb-ai.com/docs)
• Includes examples (live planner at /plan)
• Tested across Claude Code (plugin), Cursor (MCP config), Claude Desktop (MCP config), and any MCP host
• Safe — confirms before destructive operations (cancel + retry are idempotent)
• Portable across Claude platforms
• Alphabetical order maintained (inserted between D3.js and FFUF)
