# Eve Content Agent Template

A Slack-based content assistant built on [Eve](https://beta.eve.dev). Writers @mention it in
Slack and it drafts blog posts, LinkedIn posts, release notes, and newsletters in your house
voice, pulling source material from Notion and publishing approved pieces back to Notion as
the signed-in writer.

**Lives in Slack.** Answers @mentions and DMs, replies in threads, and renders approvals as buttons.**Writes in your voice.** One editable style skill per surface (blog, LinkedIn, release notes, newsletter), enforced by a deterministic style-lint tool.**Grounded in Notion.** Each writer signs in to their own Notion through Vercel Connect, so drafts are created as the real person with their own permissions, with no shared secret.**Stores files in Vercel Blob.** Export drafts, save images and attachments, and read them back, authenticated by the project's OIDC token.

Deploying with the button provisions everything the agent needs and wires it up for you:

- a
**Slack** connector (sets`SLACK_CONNECTOR`

, with the event trigger pointed at`/eve/v1/slack`

), - a
**Notion** connector (sets`NOTION_CONNECTOR`

), - a
**Vercel Blob** store for the asset tools.

Once deployed, @mention the bot in your Slack workspace to start drafting.

[Vercel Connect](https://vercel.com/docs/connect)[Vercel Blob](https://vercel.com/docs/vercel-blob), authenticated by OIDC[Vercel AI Gateway](https://vercel.com/docs/ai-gateway)(default: Claude Opus 4.8)[Vercel Sandbox](https://vercel.com/docs/sandbox)[Ultracite](https://www.ultracite.ai/)(Biome)**Zero static keys.** Authentication runs entirely on [Vercel Connect](https://vercel.com/docs/connect)
(Slack and Notion) and [Vercel OIDC](https://vercel.com/docs/oidc) (Vercel Blob and AI
Gateway). There are no API keys or client secrets to manage in code or `.env`

files: Notion is
authorized per writer in the browser, and Blob and the model authenticate with the project's
OIDC token.

Link the project you deployed (or a fresh one) and pull its environment:

```
vercel link
vercel env pull
```

Then run the development server and link a model provider with `/model`

in the TUI:

```
pnpm dev
```

You can chat with the agent directly in the dev TUI to test the drafting, style-lint, Notion, and Blob flows. The Slack surface itself only runs against a deployment. Ship changes with:

```
eve deploy
```

This project uses [Ultracite](https://www.ultracite.ai/) (a [Biome](https://biomejs.dev/)
preset) for linting and formatting:

```
pnpm check   # check formatting and lint rules
pnpm fix     # auto-fix what is fixable
```

The Deploy button provisions these for you. To set them up manually (for a project you didn't
create with the button), use the [Vercel CLI](https://vercel.com/docs/cli):

``` php
# Notion connector (note the printed UID, e.g. mcp.notion.com/notion -> NOTION_CONNECTOR)
vercel connect create mcp.notion.com --name notion

# Slack connector (note the UID, e.g. slack/<name> -> SLACK_CONNECTOR), then point its
# event trigger at the route the agent serves
vercel connect create slack --name <name> --triggers
vercel connect attach slack/<name> --triggers --trigger-path /eve/v1/slack

# Blob store, connected to the project for all environments
vercel blob create-store <name> --access public --yes
```

**Voice:** edit the per-surface skills in`agent/skills/*/SKILL.md`

, and the`references/banned-words.json`

each one lints against. Add a new surface by adding a new skill folder.**Behavior:** edit`agent/instructions.md`

.**Model:** edit`agent/agent.ts`

(or run`/model`

in the dev TUI).**Tools:** add or change tools in`agent/tools/`

. The filename is the tool name.

The agent auto-updates as you edit these files.
