+"""Extract a transcript from a claude.ai share URL.
+
+Usage (run inside browser-harness):
+    CLAUDE_SHARE_URL=https://claude.ai/share/<uuid> \
+    OUTPUT_DIR=/path/to/transcripts \
+    bh -c "$(cat agent-workspace/domain-skills/claude-ai/extract-share-transcript.py)"
+
+Requires: the user's running Chrome must be signed into claude.ai (share pages
+render the conversation only for authenticated viewers — see share-export.md).
+
+Writes two files into OUTPUT_DIR, named from the conversation title slug:
+    <slug>.json  — {title, source_url, turns: [{role, text}]}
+    <slug>.md    — Markdown with ## Human / ## Assistant headers
