eve — Claude Code skill: build backend agents on the framework

What eve does

eve is a filesystem-first framework for backend agents. An agent is a directory on disk containing instructions, skills, tools, connections, channels, subagents, and schedules. eve compiles and runs the whole thing.

The skill works in Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, and OpenCode. When you're creating, editing, or debugging an eve project, the skill guides you through syntax and file structure. Full documentation ships with the eve package—always read node_modules/eve/docs/README.md before you write eve code.

What it helps with

  • build a backend agent with persistent state
  • structure agent code as a filesystem hierarchy
  • connect tools, skills, and channels to an agent
  • set up schedules and subagents
  • test and debug agent logic

Example prompts for the agent

  • Help me create an eve agent with a tool to send emails
  • How do I add a new skill to an eve agent and wire it to a channel?
  • Debug this eve config—the agent won't trigger the schedule

# eve

eve is a filesystem-first framework for durable backend AI agents. An agent is
a directory on disk — instructions, skills, tools, connections, channels,
subagents, and schedules are all files — and eve compiles and runs it.

## Source of truth

The complete documentation ships inside the `eve` package. Do not rely on this
skill for guidance — always read the bundled docs, which match the installed
version exactly:

```
node_modules/eve/docs/
```

Start with `node_modules/eve/docs/README.md`. It contains the full
index and recommended reading order. Before writing any eve code, read the
relevant guide there first.

If `eve` is not installed yet, install it (`npm install eve`) or scaffold a new
agent with `npx eve init <agent-name>`, then read the bundled docs.
