From the SKILL.md

# Slack Agent Development Skill

This skill builds Slack agents with **eve** — Vercel's filesystem-first framework for durable backend agents — using **Vercel Connect** for Slack credentials:

- **eve** (`eve` package) — agent runtime, tools, channels, durability
- **@vercel/connect** — brokered short-lived Slack tokens; no bot tokens or signing secrets to manage

## Skill Invocation Handling

When this skill is invoked via `/slack-agent`, check for arguments and route accordingly:

### Command Arguments

| Argument | Action |
|----------|--------|
| `new` | **Run the setup wizard from Phase 1.** Read `./wizard/1-project-setup.md` and guide the user through creating a new Slack agent. |
| `configure` | Start wizard at Phase 2 or 3 for existing projects |
| `deploy` | Start wizard at Phase 5 for production deployment |
| `test` | Start wizard at Phase 6 to set up testing |
| (no argument) | Auto-detect based on project state (see below) |

### Auto-Detection (No Argument)

If invoked without arguments, detect the project state and route appropriately:

1. **No `package.json` with `eve` and no `agent/` directory** → Treat as `new`, start Phase 1
2. **Has eve project but no `agent/channels/slack.ts`** → Start Phase 2 (Slack connector + channel)
3. **Has Slack channel but no `SLACK_CONNECTOR` configured** → Start Phase 3
4. **Configured but not deployed** → Start Phase 5 (the Slack surface only works on a deployment)
5. **Deployed but no tests** → Start Phase 6
