ContextKit

Context Engineering for AI Development

Give your AI assistants (Cursor, Claude, Copilot, Codex, OpenCode, Gemini, Aider, Continue, Windsurf) structured context through markdown files. ContextKit creates a knowledge base that ensures AI generates code matching your exact patterns, style, and architecture—no more hallucinated code or mismatched conventions.

ContextKit is a CLI tool that provides context-engineering capabilities by creating .contextkit/ directories with project standards, guidelines, and patterns that AI assistants read automatically.

Why ContextKit?

The problem: LLMs are great at syntax, not at your conventions. Generic AI output requires manual fixes for style, structure, and architecture.

The solution: ContextKit provides your AI with:

• Glossary of project terminology and domain-specific terms (e.g., your entity, feature, and module names)
• Standards for code style, testing patterns, and architecture
• Templates with canonical component shapes

Update .md files as your project evolves; the AI follows.

Multi-Platform Support

Works with: Cursor • Claude Code • GitHub Copilot • Codex CLI • OpenCode • Gemini CLI • Aider • Continue • Windsurf

Each platform gets auto-loaded bridge files (CLAUDE.md, AGENTS.md, GEMINI.md, .windsurfrules, etc.) so your AI tools read project standards automatically. Claude Code uses @ imports in CLAUDE.md to load standards content directly into context — no extra token cost from manual file reads.

Quick Start (60s)

1. Install the CLI

npm i -g @nolrm/contextkit

2. Set up your project

cd your-project
contextkit install

Creates .contextkit/ with skeleton standards files in your project.

3. Generate your standards

Run /analyze in your AI tool — it scans your codebase and fills the skeleton files with your project's conventions.

Done. Your AI tools now have project-specific context.

Multi-Team Workflow

Perfect for teams where members use different AI tools:

# First team member - sets up the project with their tool
contextkit install claude   # or: contextkit install (interactive picker)

# Each additional team member adds their platform
ck claude      # creates CLAUDE.md + .claude/rules/
ck cursor      # creates .cursor/rules/ (scoped .mdc files)
ck copilot     # creates .github/copilot-instructions.md
ck codex       # creates AGENTS.md
ck opencode    # creates AGENTS.md
ck gemini      # creates GEMINI.md + .gemini/settings.json
ck aider       # creates CONVENTIONS.md + .aider/rules.md
ck continue    # creates .continue/rules/ + config.yaml
ck windsurf    # creates .windsurfrules + .windsurf/rules/
ck vscode      # alias for copilot

Each platform generates bridge files that the AI tool auto-reads. If a bridge file already exists (e.g., you have a custom CLAUDE.md), ContextKit appends its section below your content instead of overwriting. Share your .contextkit/standards/*.md files with the team and everyone gets the same context.

Prompt

"Add checkout flow for customer"

What the AI does with ContextKit

• Reads glossary.md → checkout = checkout process; customer = customer account
• Applies code-style.md → strict TS, functional components
• Follows testing.md → numbered test cases

Result (diff)

- const Checkout = () => <button>Buy</button>
+ export function CheckoutFlow({ customer }: { customer: string }) {
+   // Uses customer from glossary context
+   return <div>Checkout for {customer}</div>
+ }

Use it in your tool

Cursor — rules auto-load from .cursor/rules/, slash commands in .cursor/prompts/

/analyze    # scan codebase and generate standards
/review     # code review with checklist
/fix        # diagnose and fix bugs

Claude Code — CLAUDE.md uses @ imports to auto-load all standards into context every session (no manual reads needed, saves tokens). Slash commands in .claude/commands/.

/analyze    # scan codebase and generate standards
/review     # code review with checklist
claude "create checkout flow for customer"

GitHub Copilot — reads .github/copilot-instructions.md automatically

@.contextkit Create checkout flow for customer

Codex CLI — reads AGENTS.md automatically

codex "create checkout flow for customer"

OpenCode — reads AGENTS.md automatically

opencode "create checkout flow for customer"

CLI (Chat with AI)

ck ai "create a button"

Slash Commands

ContextKit installs reusable slash commands for supported platforms:

Claude Code — available as /analyze, /review, etc. in .claude/commands/ Cursor — available as slash commands in Chat via .cursor/prompts/

Both platforms delegate to the universal command files in .contextkit/commands/, so you maintain one set of workflows.

Squad Workflow

The squad workflow turns a single AI session into a structured multi-role pipeline. Each role has its own slash command that reads and writes to a shared handoff file (.contextkit/squad/handoff.md), simulating a team of specialists.

Pipeline Roles

Single-Task Flow

/squad "add dark mode support"        # PO writes the spec
/squad-architect                       # Architect designs the plan
/squad-dev                             # Dev implements the code
/squad-test                            # Tester writes and runs tests
/squad-review                          # Reviewer gives the verdict

Batch Flow

Pass multiple tasks to /squad and it automatically runs in batch mode:

/squad "add dark mode" "fix login bug" "refactor checkout"
# PO writes specs for all three tasks

/squad-run
# Runs Architect → Dev → Test → Review for each task sequentially

Agent mode (Claude Code only): Use /squad-run-agents instead of /squad-run to spawn parallel subagents — one per task per phase — so all tasks progress simultaneously rather than one at a time.

/squad "add dark mode" "fix login bug" "refactor checkout"

/squad-run-agents
# Phase 1: architect agents for all 3 tasks run in parallel
# Phase 2: dev→test→review pipeline runs in parallel per task

Feedback Loop

Any downstream role can raise questions for an upstream role. When this happens, the pipeline pauses and directs you to the right command:

Reviewer has questions for Dev → run /squad-dev to clarify
Tester has questions for Architect → run /squad-architect to clarify
Architect has questions for PO → run /squad to clarify

After clarifications are added, re-run the asking role's command to continue. This prevents misunderstandings from compounding through the pipeline.

Visual Assets (Optional)

If you have a screenshot, mockup, or design image relevant to the task, paste or attach it when running /squad. The PO agent will save it to .contextkit/squad/assets/ and reference the path in the handoff. Architect and Dev agents automatically read any listed assets when they pick up the handoff.

Git Hooks & Quality Gates

ContextKit can optionally install Git hooks during ck install. Uses git config core.hooksPath to point Git at .contextkit/hooks/ — no external dependencies like Husky required. Works in any git repo, not just Node.js projects.

For Node.js projects, a prepare script is automatically added to package.json so hooks activate for all developers after npm install — no need for everyone to run ck install.

Framework-Aware Quality Gates

The pre-push hook detects your project type and runs the right quality checks automatically. All gates skip gracefully when tools aren't installed.

Commit Message Format

When the commit-msg hook is enabled, all commits must follow this format:

<type>(<scope>): <description>

Types: feat, fix, docs, style, refactor, test, chore

Examples:

git commit -m "feat(auth): add login page"
git commit -m "fix: resolve null pointer in checkout"
git commit -m "docs: update API reference"
git commit -m "test(cart): add edge case coverage"

Hooks are optional and can be skipped with ck install --no-hooks.
