cursor-handbook

🌐 Live handbook: https://girijashankarj.github.io/cursor-handbook/

The open-source rules engine for Cursor IDE — 117 components (rules, agents, skills, commands, hooks) that turn your AI into a senior engineer who follows your standards, knows your codebase, and never wastes a token.

Stop teaching your AI the same things every session. cursor-handbook gives Cursor permanent memory of your standards, security policies, and workflows — across every project, every team member, every prompt.

If cursor-handbook helps you, consider giving it a ⭐ — it helps others discover it.

Ways to use cursor-handbook

Pick the option that fits your workflow:

Option	Best for
1. Clone & copy	Use the full rules engine in your repo. Clone this repo, copy the .cursor folder into your project, then edit project.json and tailor rules/agents/skills to your stack.
2. Add from GitHub (Cursor UI)	Use rules, skills, or agents without cloning. In Cursor IDE go to Settings → Rules / Skills / Agents, click Add new → Add from GitHub, and paste this repo’s clone URL. Add only what you need.

| 3. Fork & customize | Maintain your own version. Fork this repo, adapt the .cursor files for your team or product, then use that fork across your projects or share it internally. | | 4. Pick and choose | Use individual components. Download only the production-ready, generic rules, skills, agents, commands, or hooks you need from this repo and drop them into your existing .cursor setup. | | 5. Handbook website | Browse components or read Guidelines (Cursor IDE topics) in the browser — GitHub Pages (optional; clone, ZIP, and command line still work). |

Improvements welcome. If you want to add or improve rules, skills, hooks, agents, or commands, see CONTRIBUTING.md and open an issue or PR.

Forking? Replace girijashankarj with your GitHub org/username in badges, clone URLs, scripts/setup-cursor.sh, .github/CODEOWNERS, and docs before pushing.

The Problem

Every time you open Cursor IDE, your AI assistant starts from zero. It doesn't know your:

• Code conventions and architecture patterns
• Security policies (and happily hardcodes your API keys)
• Testing thresholds (and runs the full 100K-token test suite when you just wanted a type check)
• Handler patterns, naming conventions, or folder structure

You end up repeating yourself, burning tokens, and fixing the same mistakes. cursor-handbook fixes this permanently.

---

Before vs After

Before cursor-handbook	After cursor-handbook
AI hardcodes API keys	Security rules block it
AI runs full test suite (~100K tokens)	Uses type-check (~10K) or single-file tests
You repeat conventions every session	Rules remember them — always on
Inconsistent code across team	One rules engine, one standard
No guardrails on expensive ops	Hooks warn or block dangerous commands

---

Who is this for?

Audience	Benefit
Solo developers	Consistent AI behavior without repeating yourself every session
Teams	Shared standards; everyone gets the same guardrails and conventions
Enterprises	Security, compliance, and token efficiency built in from day one

    style D fill:#8b5cf6,stroke:#7c3aed,color:#fff,stroke-width:2px

One-line install

git clone https://github.com/girijashankarj/cursor-handbook.git .cursor && make -f .cursor/Makefile init

Then edit .cursor/config/project.json and restart Cursor.

Step 1 — Clone

# Into your existing project
git clone https://github.com/girijashankarj/cursor-handbook.git .cursor

Step 2 — Configure

# Option A: One-command setup
make init

# Option B: Interactive generator
./scripts/init-project-config.sh

# Option C: Manual copy
cp .cursor/config/project.json.template .cursor/config/project.json

Edit .cursor/config/project.json — replace placeholders with your project details:

{
	"project": { "name": "my-api", "description": "Order management service" },
	"techStack": {
		"language": "TypeScript",
		"framework": "Express.js",
		"database": "PostgreSQL",
		"testing": "Jest",
		"packageManager": "pnpm"
	},
	"testing": {
		"coverageMinimum": 90,
		"testCommand": "pnpm run test",
		"typeCheckCommand": "pnpm run type-check"
	}
}

Step 3 — Restart Cursor IDE

Close and reopen Cursor. All 117 components are now active.

Step 4 — Verify

Try any of these:

/type-check          → Runs type checking (saves ~90K tokens vs full tests)
/code-reviewer       → AI reviews your code like a senior engineer
/generate-handler    → Scaffolds a complete API handler

Alternative: One-Line Setup

curl -fsSL https://raw.githubusercontent.com/girijashankarj/cursor-handbook/main/scripts/setup-cursor.sh | bash

Alternative: Git Submodule (for teams)

git submodule add https://github.com/girijashankarj/cursor-handbook.git .cursor
make init
# Or: cp .cursor/config/project.json.template .cursor/config/project.json

Typical Workflows

What You Want	What You Type	What Happens
Build a new endpoint	"Create a POST /orders endpoint"	Skill triggers full handler scaffolding (9 files, 7-step flow)
Review code	/code-reviewer	Agent checks security, performance, correctness, tests
Fix broken tests	/testing-agent fix these tests	Skill diagnoses failures, fixes mocks, verifies coverage
Quick validation	/type-check	Runs type check (~10K tokens) instead of full tests (~100K)
Deploy safely	/deployment-agent	Agent generates deployment checklist with rollback plan
Optimize a query	/query-opt-agent	Agent runs EXPLAIN ANALYZE, rewrites query, adds indexes

---

Processing Pipeline

Every prompt flows through a layered processing pipeline that ensures quality, security, and efficiency:

graph TD
    subgraph L1 ["Layer 1: Pre-Processing"]
        direction LR
        A1[Context Enrichment] --> A2[Shell Guard] --> A3[Pre-Commit Check]
    end

    subgraph L2 ["Layer 2: Rules Engine — Always Active"]
        direction LR
        B1[Token Efficiency] --> B2[Security Guardrails] --> B3[Code Standards]
        B3 --> B4[Architecture] --> B5[Testing Standards]
    end

    end

    subgraph L4 ["Layer 4: Post-Processing"]
        direction LR
        D1[Edit Validation] --> D2[Auto-Format] --> D3[Coverage Check]
    end

    L1 --> L2 --> L3 --> L4

    style L1 fill:#1e293b,stroke:#475569,color:#fff
    style L2 fill:#0c4a6e,stroke:#0284c7,color:#fff
    style L3 fill:#3730a3,stroke:#6366f1,color:#fff
    style L4 fill:#1e293b,stroke:#475569,color:#fff

Layer Breakdown

Layer 1 — Pre-Processing (Hooks) Before your prompt even reaches the AI, hooks inject your project context, block dangerous shell commands, and validate git operations.

Layer 2 — Rules Engine (30 Rules, Always Active) Every AI response is shaped by your rules. These aren't suggestions — they're hard constraints:

Rule Category	What It Enforces
Token Efficiency	No auto-running full tests/lint; confirm 50K+ ops
Security	No hardcoded secrets; no PII in logs; parameterized queries
Architecture	Handler pattern; dependency direction; error hierarchy
Code Organization	Naming conventions; import order; folder structure
Database	Soft delete only; required columns; migration safety
Testing	90%+ coverage; mock patterns; AAA pattern

Layer 3 — Specialized Processing Based on your prompt, the right component activates: an agent for complex tasks, a skill for guided workflows, or a command for quick operations.

Layer 4 — Post-Processing (Hooks) After code is generated, hooks validate the output, auto-format files, scan for leaked secrets, and verify test coverage.

Token Savings

cursor-handbook is engineered to cut your AI token costs by 30% or more:

pie title Token Usage Comparison (per operation)
    "Type Check (cursor-handbook)" : 10
    "Saved vs Full Tests" : 90

Without cursor-handbook	With cursor-handbook	Tokens Saved
Full test suite: ~100K tokens	/type-check: ~10K tokens	~90K (90%)
Full lint run: ~50K tokens	/lint-check (read_lints): ~2K tokens	~48K (96%)
Full test suite: ~100K tokens	/test-single: ~5K tokens	~95K (95%)
Unfiltered context: ~30K tokens	Context layering: ~10K tokens	~20K (67%)
Verbose AI output: ~15K tokens	Concise guidelines: ~5K tokens	~10K (67%)

Conservative estimate: A developer making 50 AI interactions/day saves ~200K tokens/day — that's real money at scale.

Why You Should Use This

For Individual Developers

• Save money — 30%+ reduction in token costs adds up fast
• Save time — Stop repeating your standards every session
• Better code — AI follows your patterns, not random internet patterns
• Security by default — Guardrails prevent accidental secret leaks
• Instant scaffolding — Full handler/component in seconds, not minutes

For Teams

• Consistency — Every developer gets the same AI behavior
• Onboarding — New team members get productive on day one
• Standards enforcement — Rules apply automatically, no code review friction
• Institutional knowledge — Your patterns are codified, not tribal knowledge
• Cost control — Token savings compound across the whole team

For Organizations

• Compliance — Security and data handling rules are always enforced
• Scalability — Same standards across 10 projects or 1,000
• Governance — Central control over AI behavior across all teams
• ROI — Measurable token savings and developer time savings
• Risk reduction — No more hardcoded secrets or PII in logs
