Trellis is an open-source engineering framework and agent harness for AI coding assistants that persists project specs, tasks, and cross-session memory into your repository. It auto-injects curated context into every AI session across 20+ coding platforms (Claude Code, Codex, Cursor, Gemini CLI, and more) so agents follow your team's conventions and workflow.

Use cases

  • give AI coding agents persistent memory of my project conventions
  • inject project specs automatically into Claude Code or Codex sessions
  • enforce a spec-driven workflow on AI coding assistants
  • share coding standards and tasks with a team using AI agents
  • manage task lifecycle and context for sub-agents
  • make any coding agent follow my engineering standards
  • stop AI assistants from starting every session from scratch

When to choose

  • you use AI coding assistants (Claude Code, Codex, Cursor, etc.) and want consistent, convention-following output across sessions
  • your team needs shared, versioned specs and task memory persisted in the repo
  • you want automatic context injection and workflow enforcement rather than manually maintained rules files like .cursorrules or CLAUDE.md
  • you work across multiple AI coding platforms and want one portable framework

When to avoid

  • you want a fully autonomous coding agent rather than a harness that scaffolds and constrains existing agents
  • your project is small enough that a single rules file suffices
  • you need a permissive license - Trellis is AGPL-3.0
  • you cannot install Node.js 18+ and Python 3.9+
