Bluesky Sentiment (Go)

Small Go CLI that samples recent Bluesky posts, scores sentiment, and prints an ASCII trend chart for the last hour.

By default it uses a lightweight local word-list model (zero API cost). Optional Claude relabeling is available only for uncertain posts, with strict per-run call limits.

Why this keeps token spend low

• Local sentiment pass on all posts first.
• Only low-confidence posts are sent to Claude.
• Batches multiple posts into one Claude call.
• Hard cap with --claude-max-calls.
• Text is truncated before sending to Claude.

Quick start

go run .

Example output includes:

• Sample size in past hour
• Overall positive/neutral/negative counts
• 6 buckets of 10-minute sentiment bars (+ positive, = neutral, - negative)

Claude-assisted mode

Set your key and enable relabeling:

export CLAUDE_API_KEY="your_key_here"
go run . --use-claude --claude-model claude-3-5-haiku-latest --claude-max-calls 2

Useful flags

• --queries "the,and,that,this,with" sample terms used for public search
• --window 60 minutes of data to include
• --limit 30 posts per query term
• --max-posts 180 total deduped posts cap
• --uncertain-cutoff 1 local score threshold to escalate
• --claude-batch-size 20 posts per Claude call
• --claude-max-calls 3 max Claude calls per run

Notes

• This script uses Bluesky public search API as a lightweight approximation of "current mood".
• It is intentionally small and cheap, not a production firehose analytics pipeline.
