Social media

Typefully Social Media Agent eve Template

A Slack-based social media agent built on eve. Team members @mention it in Slack and it runs their social presence through Typefully: drafting posts and threads for X, LinkedIn, Threads, Bluesky, and Mastodon, scheduling and managing the publishing queue, uploading media, reading analytics, and pulling briefs from Notion. Long-form pieces are shared as Notion pages.

• Lives in Slack. Answers @mentions and DMs, replies in threads, and renders approvals as buttons.
• Works on your Typefully account. The connection authenticates with your Typefully API key (TYPEFULLY_API_KEY), so drafts and scheduling run against your real workspace. Plain drafting is friction-free; scheduling or publishing a post (publish_at) and deleting drafts, comments, or threads pause for approval before they run.
• Pulls from and drafts into Notion. Briefs and source material come from Notion pages through the same user-scoped OAuth flow, long-form pieces are drafted back as pages, and page updates and moves are gated on approval.
• Stores files in Vercel Blob. Export threads, save images and attachments, and read them back, authenticated by the project's OIDC token.
• Posts a weekly analytics digest. Every Monday it pulls Typefully post and follower analytics and posts two tables to a Slack channel you choose (TYPEFULLY_ANALYTICS_CHANNEL).

Deploy

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 prompt for your Typefully API key (sets TYPEFULLY_API_KEY),
• 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 working on your social posts.

Tech stack

One secret to manage. Slack and Notion authenticate through Vercel Connect, and Vercel Blob and AI Gateway through Vercel OIDC — no keys to manage for any of them. The one credential you supply is the Typefully API key, set as the TYPEFULLY_API_KEY environment variable in the Vercel project (and in .env.local for local development).

Quick start with an AI coding agent

If you're working with an AI coding agent like Claude Code or Cursor, you can use this prompt to have it help you with building your agent:

I want to build a Slack agent with the eve framework, using the Typefully social media agent template. Read the setup instructions at https://agent-resources.dev/typefully-eve-template.md and follow them. They will cover deploying the template, building with eve, how everything works overall, and more.

Pairing with the content agent template

The eve content agent template is a full content assistant with a house voice and style skills for long-form surfaces this agent doesn't cover (blog posts, release notes, newsletters). Instead of merging all of that into this agent, you can deploy it as its own agent and let this one delegate to it through eve's remote agents feature.

1. Deploy the content agent template as its own Vercel project.
2. Add a remote subagent file to this repo. The filename is the tool name, and vercelOidc() handles deployment-to-deployment auth with no shared secret:

// agent/subagents/content_writer.tsimport { defineRemoteAgent } from "eve";import { vercelOidc } from "eve/agents/auth";
export default defineRemoteAgent({  url: () => process.env.CONTENT_AGENT_URL ?? "https://your-content-agent.vercel.app",  description:    "Drafts blog posts, LinkedIn and X posts, release notes, and newsletters in the house voice. " +    "Pass the surface, the source material, and any constraints in the message.",  auth: vercelOidc(),});

3. Set CONTENT_AGENT_URL in this project's environment and mention the new subagent in agent/instructions.md so the agent knows when to hand off.

The remote agent runs in its own deployment with its own skills and connections, and it never sees this agent's conversation history, so this agent packs everything the writer needs into the call message. The result comes back as a normal tool result, the same shape as the local researcher and reviewer subagents.

Local development

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

vercel linkvercel 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 Typefully, Notion, and Blob flows. The Slack surface itself only runs against a deployment. Ship changes with:

eve deploy

Linting and formatting

This project uses Ultracite (a Biome preset) for linting and formatting:

pnpm check      # check formatting and lint rulespnpm fix        # auto-fix what is fixablepnpm validate   # lint + typecheck + eve discovery diagnostics

Setting up the connectors by hand

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:

# Typefully API key — paste your key from Typefully Settings when promptedvercel env add TYPEFULLY_API_KEY
# Notion connector (prints the UID notion/social-media-agent -> NOTION_CONNECTOR)vercel connect create notion --name social-media-agent
# Slack connector (note the UID, e.g. slack/<name> -> SLACK_CONNECTOR), then point its# event trigger at the route the agent servesvercel connect create slack --name <name> --triggersvercel connect attach slack/<name> --triggers --trigger-path /eve/v1/slack
# Blob store, connected to the project for all environmentsvercel blob create-store <name> --access public --yes

Customizing

• Behavior: edit agent/instructions.md. It describes the whole workflow: load the right skill first, ground work in the user's real social sets and drafts, draft freely but schedule and delete only on approval, draft long pieces into Notion, and get a fresh-eyes review before proposing a draft.
• Approval gates: edit the approval policy in agent/connections/typefully.ts (the DELETE_TOOLS / PUBLISH_TOOLS lists and the publish_at check) and the APPROVAL_REQUIRED_TOOLS list in agent/connections/notion.ts to change which MCP tools pause for a human decision.
• Skills: edit or add skills in agent/skills/. Each folder holds a SKILL.md plus its reference files. The five *-style skills carry per-platform guidance and a banned-words.json that the lint_against_style tool checks drafts against; writing-quality carries the generic prose rules. The reviewer subagent keeps its own identical copy of writing-quality under agent/subagents/reviewer/skills/.
• 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.
• Weekly analytics digest: set TYPEFULLY_ANALYTICS_CHANNEL to the Slack channel id it should post to. Change the day or time in agent/schedules/weekly-analytics.ts (the cron is evaluated in UTC), and edit agent/tools/post_analytics_report.ts to change the report format. In dev, trigger a run with curl -X POST http://localhost:3000/eve/v1/dev/schedules/weekly-analytics.

The agent auto-updates as you edit these files.
