1. caveman

   1 22 71,068 9.3 JavaScript

   🪨 why use many token when few token do trick — Claude Code skill that cuts 65% of tokens by talking like caveman

   

   Project mention: Stop Paying for Noise: Trim LLM Tokens from Both Ends of the Pipe | dev.to | 2026-05-27

   If RTK handles the flood of input tokens, caveman disciplines the output. It is a Claude Code skill that instructs the model to respond with minimal words. The caveman repository states it “cuts 65% of tokens by talking like caveman.”

7. career-ops

   6 2 24,191 - JavaScript

   AI-powered job search system built on Claude Code. 14 skill modes, Go dashboard, PDF generation, batch processing.

   

   Project mention: Why I forked career-ops and shut down the tool I built | dev.to | 2026-04-23

   Last month I found career-ops by Santiago Ferreira — a Claude Code-native job search system with a Go-based TUI dashboard, portal scanners, batch evaluation, and an interview story bank. It does everything Rendure did, plus most of the job search workflow Rendure never touched. I forked it, plugged my own pipeline pieces into the parts that didn't fit me, and moved on.

10. 9router

    9 2 6,614 - JavaScript

    Unlimited FREE AI coding. Connect Claude Code, Codex, Cursor, Cline, Copilot, Antigravity to FREE Claude/GPT/Gemini via 40+ providers. Auto-fallback, RTK -40% tokens, never hit limits.

    

    Project mention: 9router: route Claude Code, Cursor, or Copilot through whichever free tier you've got | dev.to | 2026-05-09

    I was crawling GitHub trending for AI infra projects when I came across decolua/9router. It's the most thoughtful "stretch your free tiers" project I've seen for AI coding tools — and it does a few things I hadn't seen combined before. Worth a 60-second rundown for anyone burning through Cursor/Claude/Copilot budgets faster than they'd like.

11. firecrawl-mcp-server

    10 1 6,503 9.0 JavaScript

    🔥 Official Firecrawl MCP Server - Adds powerful web scraping and search to Cursor, Claude and any other LLM clients.

    

    Project mention: Show HN: MCP-recorder – VCR.py for MCP servers. Record, replay, verify | news.ycombinator.com | 2026-03-06

    --target https://mcp.devhelm.io

    It works with both HTTP and stdio transports. Scenarios are defined in YAML so it works with MCP servers in any language, and there's a pytest plugin if you want tighter integration. Secret redaction and environment variable interpolation are built in.

    To make sure this actually works on real codebases, I submitted several PRs to production MCP servers: monday.com's MCP server (https://github.com/mondaycom/mcp/pull/222), Tavily's MCP server (https://github.com/tavily-ai/tavily-mcp/pull/113), and Firecrawl's MCP server (https://github.com/firecrawl/firecrawl-mcp-server/pull/175). They went from zero schema coverage to full tool surface verification with a clean schema diff available on each tool change. One big benefit is that you can do verification and replay with no API keys — deterministic responses, no live requests to real servers.

    I wrote up a deeper dive into the schema drift problem and the VCR pattern for MCP here: https://devhelm.io/blog/regression-testing-mcp-servers

12. obsidian-smart-connections

    11 26 5,095 9.7 JavaScript

    Find related notes and excerpts while writing. Your link building copilot displays relevant content in graph + list view. A local embedding model powers semantic search. Zero setup. No API key.

    

    Project mention: Think with your second brain: a proper Claude Code harness for Obsidian | dev.to | 2026-05-20

    Smart Connections (repo) is the dominant Obsidian-AI plugin and does RAG over the vault. The harness uses Smart Connections' embedding cache as a secondary signal in Hybrid Mode, not as the primary retrieval mechanism.

13. playwright-skill

    12 2 2,754 7.3 JavaScript

    Claude Code Skill for browser automation with Playwright. Model-invoked - Claude autonomously writes and executes custom automation for testing and validation.

    

    Project mention: I Tried and Failed to Rebuild the 1996 Space Jam Website with Claude | news.ycombinator.com | 2025-12-07

    Just use Playwright Skill (https://github.com/lackeyjb/playwright-skill). It is a game changer. Otherwise it is Claude the Blind, as OP mentioned.

14. openusage

    13 1 2,142 - JavaScript

    Burning through your subscriptions too fast? Paying for stuff you never use? Stop guessing. OpenUsage is free and open source.

    

    Project mention: OpenUsage: Track all your AI usage, in one panel | news.ycombinator.com | 2026-04-30

15. pro-workflow

    14 1 1,907 - JavaScript

    Claude Code learns from your corrections: self-correcting memory that compounds over 50+ sessions. Context engineering, parallel worktrees, agent teams, and 17 battle-tested skills.

    

    Project mention: Stop Rebuilding Your Claude Code Setup - Scaffold It Once with Worclaude | dev.to | 2026-04-16

    The workflow draws from Boris Cherny's tips (creator of Claude Code at Anthropic), patterns from Affaan Mir's everything-claude-code (Anthropic hackathon winner), Karpathy's coding principles, and community repos like pro-workflow.

16. avoid-ai-writing

    15 2 1,690 7.9 JavaScript

    Skill that audits and rewrites content to remove AI writing patterns. Use it with your favorite agents including Claude Code, OpenClaw, and Hermes.

    

    Project mention: AGENTS.md, SKILL.md, DESIGN.md: How AI Instructions Split into Three Layers | dev.to | 2026-05-02

17. garden-skills

    16 1 1,248 - JavaScript

    ConardLi's open-source Skills collection, featuring web design, knowledge retrieval, image generation, and more.

    

    Project mention: How to Stop Your AI Coding Assistant From Being Useless at Specialized Tasks | dev.to | 2026-04-25

    As your collection grows, structure matters. A pattern I've seen work well — and one used by open-source skill collections like ConardLi's garden-skills on GitHub — is grouping skills by capability domain:

18. claude-delegator

    17 1 963 - JavaScript

    Delegate tasks to Codex and Gemini directly from within Claude Code. (by jarrodwatts)

    

    Project mention: One model is a guess. Three that agree is a plan. | dev.to | 2026-05-18

    I did not invent the delegation layer. claude-delegator is a fork of Jarrod Watts' original (MIT, upstream currently quiet), fully based on his design - I kept the structure and the license.

19. claude-unofficial-api

    18 2 743 8.2 JavaScript

    Unofficial API for Claude-2 via Claude Web (Also CLI)

    

20. chatgpt-artifacts

    19 1 511 9.4 JavaScript

    Bring Claude's Artifacts feature to ChatGPT

    

21. Lynkr

    20 12 447 9.2 JavaScript

    Streamline your workflow with Lynkr, a CLI tool that acts as an HTTP proxy for efficient code interactions using Claude Code CLI.

    

    Project mention: LiteLLM vs Lynkr for AI Coding Workflows: Where the Token Savings Actually Come From | dev.to | 2026-06-10

    I built Lynkr, so take this as a founder comparison. I’ll keep it honest: LiteLLM is a solid provider abstraction layer. But if your goal is specifically to reduce spend in Claude Code, Cursor, or Codex-style workflows, the difference is not “which gateway supports more providers.” The difference is whether the gateway cuts tokens before they reach the model.

22. claude-code-hooks

    21 1 418 5.8 JavaScript

    🪝 A growing collection of useful Claude Code hooks. Copy, paste, customize. (by karanb192)

    

    Project mention: Show HN: Claude Code Hooks – Block dangerous commands, protect secrets | news.ycombinator.com | 2026-01-26

23. cross-code-organizer

    22 4 335 8.7 JavaScript

    Cross-Code Organizer (formerly Claude Code Organizer): cross-harness config dashboard for Claude Code, Codex CLI, MCP servers, skills, memories, agents, sessions, security scanning, context budget, and backups.

    

    Project mention: Your Claude Code Settings Will Die With Your Machine | dev.to | 2026-04-07

    The scanner is extracted from Claude Code Organizer, so it knows exactly where to look. Not just ~/.claude/. It finds project-scoped .claude/ directories too, and decodes those hashed paths under ~/.claude/projects/.

24. InverseUI-Recorder

    23 1 333 6.0 JavaScript

    Intent-based UI automation that runs locally. Record real workflows, generate reusable scripts, and safely use local credentials and files.
