MCP server registration and workflow skill for answering data questions against the Chord warehouse.
The Claude Code plugin + standalone skill for answering data questions against the Chord warehouse using the Chord Copilot MCP server.
This repo ships two install paths from the same source of truth — pick whichever fits your client:
curl | bash script that drops
SKILL.md into ~/.claude/skills/chord-copilot/. Useful for Claude
Desktop or any MCP client that reads SKILL.md but doesn't support
Claude Code plugins. Requires a separate claude mcp add step.The MCP server itself (the wren-ai-service implementation) lives in a separate Chord repo. This repo only contains the user-facing onboarding artifacts.
Two commands. The first adds this repo as a plugin marketplace; the second installs the chord-copilot plugin from it.
/plugin marketplace add chordcommerce/chord-copilot
/plugin install chord@chord
That installs:
chord-copilot MCP server (via the bundled .mcp.json) — no
separate claude mcp add step needed.copilot workflow skill (from skills/copilot/SKILL.md), which
appears in Claude Code as chord:copilot.Restart Claude Code and you're done.
The plugin's .mcp.json points at http://localhost:5555/mcp/ by
default. If your wren-ai-service runs elsewhere, edit the installed
copy under ~/.claude/plugins/ or override via claude mcp commands.
Two steps, in order:
# Local wren-ai-service:
claude mcp add chord-copilot --transport http http://localhost:5555/mcp/ --scope user
# Or any deployed instance: swap in your wren-ai-service host.
curl -fsSL https://raw.githubusercontent.com/chordcommerce/chord-copilot/main/install.sh | bash
Restart your client.
install.sh options./install.sh [--scope user|project] [--project-dir <path>] [--ref <ref>] [--force]
--scope user (default) → ~/.claude/skills/chord-copilot/.--scope project → <project-dir>/.claude/skills/chord-copilot/.--project-dir <path> — defaults to pwd.--ref <branch|tag|sha> — pin which version of SKILL.md to fetch
(also CHORD_SKILL_REF env var). Defaults to main.--force — overwrite an existing install without prompting.claude mcp list # should show `chord-copilot` connected
ls ~/.claude/skills/ # standalone install path
ls ~/.claude/plugins/ # plugin install path
Then ask Claude "How many orders did we have last month?" — the skill
should auto-trigger and walk through the retrieval-grounded SQL workflow:
search_schema → search_saved_views / search_sql_pairs →
search_instructions → draft SQL → execute_sql.

Covers scientific figures, manuscript writing and polishing, reviewer assessment, citation retrieval, data availability, paper reading, literature search, response letters, paper-to-PPTX conversion, and evidence-grounded Chinese invention patent drafting. Rules are organized as reusable skill folders with explicit workflows and quality checks.
Persistent file-based planning for AI coding agents. Crash-proof markdown plans (task_plan.md, findings.md, progress.md) that survive context loss and /clear, with an opt-in completion gate and multi-agent shared state. Manus-style. Works with Claude Code, Codex CLI, Cursor, Kiro, OpenCode and 60+ agents via the SKILL.md standard. Includes Arabic, German, Spanish, and Chinese (Simplified and Traditional).
