- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
- Added local CONNECT proxy with TLS interception to capture Claude API traffic.
- Drives Claude Code via headless PTY/xterm and extracts the first /v1/messages exchange.
- Added `claude:trace` npm script and CLI with JSON/text output modes.
- Added integration test using a fake Claude script against a local TLS server.
