buildarc – Convert Claude Code sessions into ready-to-post content

Summary: buildarc is a CLI tool that processes all Claude Code session transcripts to extract key moments like decisions and pivots, then formats them into content suitable for platforms such as Twitter and LinkedIn. It automates content creation from raw session data without uploading any information externally.

What it does

buildarc parses multiple Claude Code .jsonl session files at once, scrubs sensitive data, and outputs formatted posts, threads, and build journals. It runs locally using only Node.js built-ins and requires a single command: npx buildarc.

Who it's for

It is designed for developers and creators who use Claude Code and want to convert their session histories into public content efficiently.

Why it matters

buildarc solves the challenge of manually extracting and formatting extensive session data into shareable content, enabling users to document their build process without reopening raw files or exposing data externally.
