Cursor & Agent Configs

⚠️ Archived — no longer maintained (as of June 2026). This repo is read-only. The configs still work and are public domain — copy what's useful. For current, living guidance see agents.md and the Cursor docs. See SUNSET.md for why, and MIGRATION.md for the history.

Copy-paste configuration for getting the most out of Cursor and other AI coding agents in 2026 — built around the primitives Cursor actually ships today: AGENTS.md, scoped rules, subagents, Skills, and hooks.

This repo was rebuilt in 2026. It started in early 2025 as a pile of giant always-on .mdc rules — an approach that's now an anti-pattern (it burns context and predates subagents/Skills/hooks entirely). If you used the old version, see MIGRATION.md.

The five primitives — and when to use each

Rule of thumb: AGENTS.md first. Add a scoped rule only when you hit a real scoping need; reach for a subagent/Skill/hook when the job is delegation, on-demand knowledge, or hard enforcement respectively.

Also in here

• Stack starter packs — templates/: copy a ready AGENTS.md + matching scoped rule for Next.js, Python (uv), or Go.
• One config, every agent — scripts/sync-agents.sh generates CLAUDE.md / .github/copilot-instructions.md / GEMINI.md from your AGENTS.md. See docs/cross-tool.md.
• Hooks cookbook — examples/hooks/: more ready-to-wire hooks (block committing secrets, inject git context at session start, run the matching test on save).
• /init-agents-md — a Skill that inspects your repo and drafts an AGENTS.md for you.

Quick start

Copy what you want — nothing here requires a build step, Node, or npm.

git clone https://github.com/DVC2/cursor-agent-configs.git

# Option A: scripted (interactive, backs up anything it would overwrite)
cd your-project && /path/to/cursor-agent-configs/scripts/install.sh

# Option B: manual — copy only the pieces you want
cp -r cursor-agent-configs/.cursor/agents   your-project/.cursor/
cp -r cursor-agent-configs/.cursor/skills   your-project/.cursor/
cp    cursor-agent-configs/templates/AGENTS.md  your-project/AGENTS.md   # then edit it

Then restart Cursor. Rules auto-attach by glob; Skills/subagents load on demand (invoke a subagent with /code-reviewer, a Skill with /debug).

⚠️ Hooks run shell scripts on agent events. Read .cursor/hooks/*.sh before installing them, and only commit hooks your team trusts. They require jq.

Verify it loaded

• Rules: open a .ts/.js file — the matching rule attaches in the agent's context panel.
• Subagents/Skills: type / in Agent and confirm code-reviewer, debug, etc. appear.
• Hooks: jq . .cursor/hooks.json should parse; try a blocked command to see the guard fire.

Compatibility

Subagents and Skills require Cursor 2.4+ (nested subagents: 2.5+). AGENTS.md and .cursor/rules work broadly. The legacy single-file .cursorrules is deprecated — migrate to AGENTS.md + .cursor/rules.
