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.team-design-ui | Team-based design exploration — spawns creative director, product designer, visual designer, interaction designer, accessibility designer | | /devlyn.design-system | Design system reference and guidance | | /devlyn.update-docs | Sync all project docs with current codebase — cleans stale content, preserves roadmaps, generates missing docs | | /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

1. Run npx devlyn-cli in your project
2. The CLI copies the config files into .claude/
3. Claude Code automatically reads .claude/commands and .claude/skills
4. 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
