Schedule BlueSky Posts Using Google Sheets
Schedules BlueSky posts from a Google Sheet, handling threads and images, then updates the sheet with live post URLs.
What it does
You schedule BlueSky posts, threads, and image attachments directly from a Google Sheet without manual posting. The system automatically identifies ready content, publishes it with live URLs, and updates your sheet so you can track every post's status instantly.
Step by step
- Parse the Google Sheet rows to filter for status 'Ready' and group them by Thread ID.
- Download image files from provided URLs into memory or temporary storage before posting.
- Send HTTP POST requests to the BlueSky API endpoints for post creation and image upload.
- Update the specific row in Google Sheets with the new post URI and change status to 'Posted'.
Where the LLM does the work
- Generate the actual text content for posts if the sheet contains only prompts or outlines rather than final copy.
- Determine optimal thread breaks and formatting to ensure readability across different client displays.
- Handle complex error messages from the BlueSky API by deciding whether to retry, skip, or flag the row.
Watch out for
Image uploads require specific blob handling and content type headers so ensure your code correctly formats the multipart request.
Thread IDs must be unique per thread but consistent across all posts in that thread so validate this logic before batching.
Google Sheets API quotas can fill up quickly if you update every row individually so batch updates where possible.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Schedule BlueSky Posts Using Google Sheets: Schedules BlueSky posts from a Google Sheet, handling threads and images, then updates the sheet with live post URLs. ## Specification - What it does: You schedule BlueSky posts, threads, and image attachments directly from a Google Sheet without manual posting. The system automatically identifies ready content, publishes it with live URLs, and updates your sheet so you can track every post's status instantly. - Trigger: On a schedule (Scheduled · daily check for ready posts) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Google Sheets: Content calendar and status tracking - HTTP Request: Posting to BlueSky API - Code: Logic for threading and image handling ## Known pitfalls, handle each one explicitly in your implementation 1. Image uploads require specific blob handling and content type headers so ensure your code correctly formats the multipart request. 2. Thread IDs must be unique per thread but consistent across all posts in that thread so validate this logic before batching. 3. Google Sheets API quotas can fill up quickly if you update every row individually so batch updates where possible. ## Reference implementation https://n8n.io/workflows/12153 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Spreadsheet than Google Sheets?
Yes. Google Sheets is only the example spreadsheet in this recipe. The same flow works with Airtable, Baserow and Excel. Swap the spreadsheet connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for marketers who'd rather brief an agent than start from a blank doc.
