Within seconds, the bot replies in-thread with a structured summary \u2013 name, location, years of experience, top 3 skills, last 3 roles, education, salary expectations, and LinkedIn \u2013 plus an action card to save the candidate to a Google Sheet for follow-up.\n\nBuilt for fast, mid-call lookups (not batch screening). Pairs with **Workflow B** which handles the Save to Sheet button.\n\n## \u2699\ufe0f How It Works\n1. **Watch Channel for Messages** listens for new messages in your CV channel\n2. **Guard: Ignore Self & No-File Filter** skips the bot's own posts and plain text messages\n3. **Guard: Supported MIME** filters to PDF, PNG, or JPG only\n4. **Download File from Slack** fetches the binary using a Bearer token\n5. **easybits: Extract CV Fields** pulls 8 structured fields from the CV\n6. **Build Summary & Action Card** formats the Slack summary + Block Kit payload\n7. **Post Summary to Thread** posts the markdown summary\n8. **Post Action Card to Slack** posts the buttons via direct API call\n\n## \ud83d\udee0\ufe0f Setup Guide\n### 1. Install the easybits Extractor node\n**n8n Cloud:**\n- Open n8n \u2192 **Settings \u2192 Community nodes \u2192 Install**\n- Enter `@easybits/n8n-nodes-extractor` and click install\n- Refresh \u2013 the **easybits Extractor** node will appear in your node panel\n\n**Self-hosted n8n:**\n- SSH into your n8n instance\n- Run: `npm install @easybits/n8n-nodes-extractor` (in your n8n root directory)\n- Restart your n8n instance\n- The Extractor node will appear after restart\n\n**Get your API key:**\n- Sign up at `https://go.easybits.tech/cn` (free plan supports up to 10 fields per Extractor \u2014 this workflow uses 8)\n- Create an Extractor for CVs with the 8 fields documented in the **Extract & Format** sticky\n- Copy your API key, then in n8n: **Credentials \u2192 Add credential \u2192 easybits Extractor API** and paste\n\n### 2. Create the Slack app\nGo to api.slack.com/apps \u2192 **Create New App**:\n- **Bot Token Scopes:** `chat:write`, `files:read`, `channels:history`, `channels:read`\n- **Event Subscriptions:** subscribe to `message.channels`\n- Install to workspace and copy the **Bot User OAuth Token** (`xoxb-...`)\n- Invite the bot to your CV channel: `/invite @YourBotName`\n\n### 3. Set up n8n credentials\n- **Slack API** credential \u2013 for the trigger node\n- **Header Auth** credential \u2013 name: `Authorization`, value: `Bearer xoxb-...` (uses your bot token). Needed for the file download and the action card HTTP call.\n\n### 4. Configure the workflow\n- Set the channel in **Watch Channel for Messages**\n- Replace `UYOURBOTID` in **Guard: Ignore Self & No-File Filter** with your actual bot user ID\n- Attach the Slack and Header Auth credentials to all nodes that need them\n\n### 5.
