Posting to ATProtocol

Short Posts (Bluesky)

300 grapheme limit. Facets required for @mentions and URLs (byte offsets, not char offsets).

# Single post
uv run python tools/thread.py "Post text here"

# Thread
uv run python tools/thread.py "Post 1" "Post 2" "Post 3"

# Reply thread
uv run python tools/thread.py --reply-to at://did:.../app.bsky.feed.post/... "Reply 1" "Reply 2"

# From file (posts separated by '---')
uv run python tools/thread.py --file draft.txt

tools/thread.py handles facet detection automatically for @mentions and URLs.

Common Errors

• 300 grapheme limit - Split into thread or use GreenGale
• Mentions not linking - Check facets with correct byte offsets
• Thread posts not connecting - Verify root and parent refs
