Bluesky Repost Caption

Purpose

Write a short caption to accompany a Bluesky repost of the full newsletter.

Inputs

• Required: MONTH: YYYY-MM
• Optional: START_DATE: YYYY-MM-DD
• Optional: END_DATE: YYYY-MM-DD
• Optional: CACHE_DIR: default .cache
• Optional: HIGHLIGHTS: list of must-include items

Steps

1. Determine the date range. Use START_DATE and END_DATE if provided, otherwise use the full calendar month for MONTH.
2. Load cached data from .cache/YYYY-MM/summary.json and per-repo JSON files. If missing, run the cache refresh skill first.
3. Select 1 key highlight to tease the newsletter.
4. Draft a single caption that stays under 240 characters.
5. Use a relaxed, all-lowercase tone.
6. Use plain text only. Do not use Markdown links or images.
7. Do not include links in the repost caption. If a link is explicitly requested, put it on its own line.
8. Limit hashtags to 0 to 1. Avoid @ mentions unless requested.
9. Save to newsletter/YYYY-MM/bluesky-repost.md.

Output

• The Markdown file path.
