Tecgos AI Kit CLI

Build smarter with AI-powered development workflows.

Tecgos AI Kit prepares a repository for AI-assisted development. It generates a root AGENTS.md, specialist agents, skills, workflows, planning artifacts, and editable architecture diagrams so your AI host starts with clear rules instead of guesses.

The CLI writes files and instructions. It does not run a model, execute subagents, or contact an AI provider.

  • One-command workspaceGenerate AGENTS.md, specialist agents, skills, workflows, and planning artifacts with the init command.
  • Bring your stackStart frontend, backend, fullstack, mobile, or existing repositories with recommended values preselected.
  • Plan before codingUse plan, spec, and task commands to leave a written trail before implementation.
  • Editable diagramsGenerate Excalidraw diagrams for system context, flows, and other architecture views.
  • Configure your AI hostWrite project-scoped configuration for Codex, Claude Code, Copilot, Cursor, OpenCode, and other supported hosts.

Illustrative commands for the published package. The CLI writes the workspace; your AI host does the rest.

Install

Start with one command.

Requires Node.js 20.11+.

Or install globally: npm install -g tecgos-ai, then tecgos-ai init.

$ npx tecgos-ai init

No telemetry or API keys. Generation works offline, and the CLI never edits global host configuration.
