"""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
