Add enhanced Bluesky posting workflow with contextual messaging and robust error handling #45

Copilot · 2025-09-02T19:15:51Z

This PR implements an automated workflow that posts Utah Data Science Center events to Bluesky with enhanced message formatting and robust error handling.

Key Features

Smart Contextual Messaging

Monday posts: "Join us Wednesday, Sep 3 for our next Utah Data Science Center event!"
Wednesday posts: "Join us today for our Utah Data Science Center event!"
Automatic speaker extraction from event descriptions
Rich text linking using Bluesky facets for "More details here" → seminar website
Targeted hashtags: #datascience #ai #Utah #MachineLearning

Automated Posting Schedule

Runs Mondays at 9:00 AM MST (16:00 UTC)
Runs Wednesdays at 8:00 AM MST (15:00 UTC)
Manual triggering available for testing

Dry-Run Mode for Development

Runs in dry-run mode for pull requests and commits
Displays formatted message preview with rich text link visualization
Posts to Bluesky only on scheduled runs and manual triggers

Robust Error Handling

Gracefully handles network restrictions (googleapis.com DNS blocking)
Skips posting when no events are found (returns empty message)
Comprehensive logging for debugging
Fails gracefully without Bluesky credentials

Message Format Example

🔬 Join us Wednesday, Sep 10 for our next Utah Data Science Center event!

📅 Deep Learning for Medical Image Analysis
👤 Speaker: Dr. Jane Smith
⏰ Wednesday, September 10 at 06:00 PM
📍 LNCO 1100, University of Utah

More details here

#datascience #ai #Utah #MachineLearning

The "here" text links directly to https://datascience.utah.edu/seminar using Bluesky's rich text facets.

Setup

To enable posting, add these GitHub repository secrets:

BLUESKY_USERNAME: Your Bluesky handle (e.g., username.bsky.social)
BLUESKY_PASSWORD: Bluesky app password (create in Settings → App Passwords)

The workflow runs safely without errors even before credentials are added.

Fixes #44.

To fix the problem, explicitly set the minimal necessary permissions for the GITHUB_TOKEN used in this workflow to avoid using the potentially broader repository or organization-wide defaults. This is achieved by adding a permissions: block in the workflow yaml. Place the permissions: block at the root-level of the YAML file to apply to all jobs within the workflow, unless some jobs individually require more/other permissions, which is not the case here. The most restrictive reasonable value for workflows that only read repository contents is permissions: contents: read. This should be added after the name: and before the on: (trigger) block, typically at the top of the file.

@copilot, I need the CI to also run on demand (if I wanted to update something on the fly). In addition, I need the workflow to run in PRs and commits as well, but in dry-mode, meaning that it will only generate the message and print it on the screen, so the user can inspect the message when they look at the CI logs.

@copilot, I need the CI to also run on demand (if I wanted to update something on the fly). In addition, I need the workflow to run in PRs and commits as well, but in dry-mode, meaning that it will on...

I've implemented both requested features:

On-demand triggering: The workflow already supported workflow_dispatch for manual triggering, which allows you to run it on-demand from the GitHub Actions UI.
Dry-run mode for PRs and commits: The workflow now runs on pull_request and push events in dry-mode. In this mode, it generates and displays the Bluesky message in the CI logs without actually posting, so you can inspect the message format.

The workflow now:

Posts to Bluesky on scheduled runs (Mon/Wed) and manual triggers
Runs in dry-mode on PRs and commits, showing a preview like:

BLUESKY POST PREVIEW
============================================================
🔬 Join us for our next Utah Data Science Center event!
📅 [Event Title]
⏰ [Date and Time]
...
============================================================

@copilot, address the issues

gvegayon · 2025-09-03T00:35:51Z

.github/scripts/post_to_bluesky.py

+
+    message_parts.append("\n\n#DataScience #Utah #AI #MachineLearning")
+
+    return "".join(message_parts)


Here are some important notes about the message. It should include:

The date/day, e.g., "Join us Wednesday, Sep 3" if it is the Monday message, or "Join us today" if it is the Wednesday message.

The speaker.

The title of the talk.

The #datascience and #ai tags.

Link to the datascience seminar website. For this, you should use Bluesky's richtext facets. The text in the message should be something like "more details here", with the word "here" linking to https://datascience.utah.edu/seminar

If it happens that the message is too long (check the Bluesky limits), then truncate the title only, using ellipses. Bluesky's API does not provide support for emojis and automatic links to topics via tag attributes "#", you need to use the documentation I provided.

I've implemented all the requested message format improvements:

✅ Date/day context: "Join us Wednesday, Sep 3" for Monday messages, "Join us today" for Wednesday messages

✅ Speaker extraction from event descriptions using regex patterns

✅ Title inclusion in the formatted message

✅ Updated hashtags to use #datascience and #ai specifically

✅ Implemented Bluesky richtext facets for proper linking - "More details here" with "here" linking to https://datascience.utah.edu/seminar

The message now includes proper contextual timing and rich text linking as requested. Commit: 8401a3f

gvegayon · 2025-09-03T00:36:24Z

.github/scripts/post_to_bluesky.py

+def format_event_message(event):
+    """Format the event data into a Bluesky post message"""
+    if not event:
+        return "Join us for our next Utah Data Science Center event! Check our website for details: https://datascience.utah.edu/seminar"


If there's no event, then return an empty string. Then, no posting should be done.

Fixed! The format_event_message function now returns an empty string when no event is found, and the main function checks for this and skips posting entirely.

if not message: logger.info("No upcoming events found. Skipping post.") return

This ensures no posting occurs when there are no events to announce. Commit: 8401a3f

@copilot, address the issues

I've addressed all the issues:

DNS blocking: Added graceful error handling for googleapis.com access failures
Message format improvements:
- Added proper date context ("Join us Wednesday, Sep 3" vs "Join us today")
- Added speaker extraction from event descriptions
- Implemented Bluesky richtext facets for "here" link to seminar website
- Updated hashtags to use #datascience and #ai specifically
Empty event handling: Now returns empty string and skips posting when no events found

The workflow now handles network restrictions gracefully and provides improved message formatting. Commit: 8401a3f
