Thread: how I wired streaming tool-use with the Claude API in ~40 lines. The trick is buffering partial JSON until the block closes.
for await (const ev of stream) {
if (ev.type === 'content_block_delta')
buf += ev.delta.partial_json ?? '';
if (ev.type === 'content_block_stop')
handleTool(JSON.parse(buf)), buf = '';
}
Tiny tool of the week: paste a messy meeting transcript, get back decisions + owners + due dates as a checklist.
74Made a CLI that turns any error stack trace into a plain-English explanation + a likely fix. Pipe stderr into it.
