## [Unreleased]
## [0.1.21] - 2026-03-24
### Added
- `edit_file` tool for targeted string replacement edits (no external API required)

- `web_fetch` tool for fetching URL content as readable text
- Syntax highlighting inside diffs with line numbers
- Streaming infrastructure for Anthropic SSE API (disabled pending incremental markdown rendering)
