Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (devlyn-cli) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

devlyn-cli

A shared configuration toolkit for Claude Code — standardize AI-powered workflows across your team and projects.

Why devlyn-cli?

Claude Code is powerful out of the box, but teams need consistent workflows — shared commands, proven prompts, commit conventions, and reusable skills.

devlyn-cli installs a curated .claude/ configuration into any project, giving your team:

Battle-tested slash commands for debugging, code review, UI design, and more
Reusable AI agent skills for debugging, code review, and UI implementation
Product and feature spec templates
Commit message conventions

Zero dependencies. One command. Works with any project.

Quick Start

npx devlyn-cli

That's it. The interactive installer walks you through the setup.

# Non-interactive mode (for CI/CD)
npx devlyn-cli -y

# Update to the latest config
npx devlyn-cli@latest

# List all available commands and templates
npx devlyn-cli list

Commands

Slash commands are invoked directly in Claude Code conversations (e.g., /devlyn.resolve).

Command	Description
`/devlyn.resolve`	Systematic bug fixing with root-cause analysis and test-driven validation
`/devlyn.team-resolve`	Team-based issue resolution — spawns specialized agent teammates (root cause analyst, test engineer, security auditor, etc.)
`/devlyn.review`	Post-implementation code review — security, quality, best practices
`/devlyn.team-review`	Team-based multi-perspective code review — spawns specialized reviewers (security, quality, testing, product, performance)
`/devlyn.design-ui`	Generate 5 distinct UI style explorations from a spec or reference image
`/devlyn.implement-ui`	Team-based UI implementation/improvement — spawns component architect, UX engineer, accessibility engineer, responsive engineer, visual QA
`/devlyn.feature-spec`	Transform product specs into implementable feature specifications
`/devlyn.product-spec`	Generate or incrementally update product spec documents
`/devlyn.discover-product`	Scan a codebase to generate feature-oriented product documentation
`/devlyn.recommend-features`	Prioritize top 5 features to build next based on value and readiness
`/devlyn.design-system`	Design system reference and guidance
`/devlyn.handoff`	Create structured handoff docs for context window transitions

Skills

Skills are triggered automatically based on conversation context.

Skill	Description
`root-cause-analysis`	5 Whys methodology, evidence standards, and no-workaround rules for debugging
`code-review-standards`	Severity framework, quality bar, and approval criteria for code reviews
`ui-implementation-standards`	Design system fidelity, accessibility, animation quality, and responsive standards for UI work

Templates

Template	Description
`template-product-spec.md`	Comprehensive product specification template
`template-feature.spec.md`	Feature specification template
`prompt-templates.md`	Reusable prompt snippets for common tasks

Optional Skills & Packs

During installation, you can choose to add optional skills and third-party skill packs:

Addon	Type	Description
`cloudflare-nextjs-setup`	skill	Cloudflare Workers + Next.js deployment with OpenNext
`prompt-engineering`	skill	Claude 4 prompt optimization using Anthropic best practices
`pyx-scan`	skill	Check whether an AI agent skill is safe before installing
`vercel-labs/agent-skills`	pack	React, Next.js, React Native best practices
`supabase/agent-skills`	pack	Supabase integration patterns
`coreyhaines31/marketingskills`	pack	Marketing automation and content skills

How It Works

Run npx devlyn-cli in your project
The CLI copies the config files into .claude/
Claude Code automatically reads .claude/commands and .claude/skills
Invoke commands like /devlyn.resolve in your Claude Code session

The installation is idempotent — run it again at any time to update to the latest config.

Requirements

Node.js 18+
Claude Code CLI
