Boost OS for Cursor

Make Cursor's agent work like a senior engineer

Cursor's agent is fast, agreeable, and has no memory of your last session. Boost OS adds the layer Cursor doesn't ship: 20 slash commands you invoke from the chat, guards that run automatically at commit and push time, and project memory every new chat starts from.

It installs into your repo as plain files, so it rides along in git and works for everyone who opens the project in Cursor. There is no extension and no settings to sync.

How it installs in Cursor

Paste one prompt into Cursor. No terminal.

Click the onboarding pill, paste one prompt into Cursor
The kernel lands in AGENTS.md, which Cursor's agent reads on every task
Commands install to .agents/skills/. Type /os in Cursor's chat to see the menu
All six always-on guards wire into .cursor/hooks.json across Cursor's shell, file-edit, and session events
Project memory scaffolds in .agents/memory/, detected from your actual stack

Where Cursor users start

The full menu

Every command below installs with that one prompt and appears in your Cursor chat the moment you type the slash. Browse all 20 commands.

/os: list every Boost OS slash command available in this project, grouped by category
/cost: break down a feature or vendor across money, build time, learning curve, lock-in, and ongoing maintenance
/design: shape a vague feature idea into a plan you can hand to /preflight before any code gets written
/explain: translate the previous output into plain language for a non-coder
/next: draft 2-3 builder-friendly prompts you could send next, based on the recent chat
/spawn: fan a task into parallel subagents when the work has independent parts
/audit: find legacy and dead code in a bounded scope, then delete with per-file confirmation
/health: check production error logs for a service in your stack and surface a grouped report
/mobile: audit one screen for mobile readiness and hand back a numbered plan you can give to /preflight
/preflight: audit a plan against the existing codebase to catch drift, bloat, redundancy, and misalignment before you start coding
/security: pre-deploy safety sweep across secrets, env hygiene, dependency advisories, and risky API routes
/sync: sync the agent's knowledge of installed library versions so it stops writing against outdated APIs
/vibe: sanity-check your uncommitted work and tell you whether you're on track or about to ship a problem
/forget: delete a saved subsystem reference
/recall: read a saved subsystem reference and pull its contents into the current chat
/remember: capture what this session learned about a subsystem into a reference file
/new: build your own custom slash command for this project through a short conversation
/pause: turn off the always-on parts of Boost OS without removing anything; /resume brings them back
/resume: turn the always-on parts of Boost OS back on after a pause
/uninstall: cleanly remove Boost OS from the project, including managed skills, project memory, and references (your own commands stay)
/update: check for and install Boost OS updates from any AI chat: newer commands, kernel improvements, fixes
/whats-new: see what shipped since your installed version, without installing anything
