The 7 AI Skills Every Software Developer Should Have Installed in 2026
After testing dozens of developer-focused AI skills, these are the seven that have proven genuinely useful across different tech stacks and workflows β not just impressive demos, but tools that hold up under daily use.
Staying on top of communications across multiple channels is a real challenge for modern teams. Signal CLI helps by enabling send signal messages and look up signal recipients via the local signal-cli installation on macos. use when the user asks to message someone on signal, send a signal text/attachment, list signal contacts, or resolve a recipient by name/nickname/phone number directly from your AI assistant, without switching apps or logging into separate platforms.
Signal CLI works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) β an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Signal CLI once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.
Getting started with Signal CLI takes about two minutes. Place the skill at `~/.claude/skills/signal-cli/` (personal, all projects) or `.claude/skills/signal-cli/` (project-specific), then restart your AI client. From that point, typing `/signal-cli` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.
Signal CLI has been installed 2,006 times, making it one of the more actively used skills in the Communication category. The install rate suggests it solves a real, recurring need rather than a niche edge case. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
Place the skill folder at ~/.claude/skills/signal-cli/ for personal use (all projects), or .claude/skills/signal-cli/ for project-specific use. Restart your AI client, then invoke with /signal-cli or let the AI discover it automatically.
Signal CLI supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
