- Fixed `SYSTEM.md` integration to correctly include custom-rendered sections like rules and skills.
- Consolidated system prompt validation by requiring `<skills>` tag presence instead of specific prose.
- Removed redundant system prompt math-formatting tests and orphaned task batch documentation tests.
- Replaced regex-based markdown detection with a stateful parser in `detectLiveReflowingMarkdown`.
- Correctly ignore table delimiters and mermaid markers when they appear inside fenced code blocks.
- Added tests to verify that code blocks containing markdown-like syntax do not prevent commit stability.
- Prevent object reference sharing between agent snapshots and stream events by deep-cloning tool-call arguments.
- Stabilize GFM tables and Mermaid diagrams during streaming by delaying transcript block commits until content finalization.
- Implement session resume safety to prevent crashes when working directories are missing.
- Add comprehensive test suites to verify streaming commit stability and immutable snapshot isolation.
beautiful-mermaid@1.1.3 measures label width in UTF-16 code units, but
terminals render East Asian characters (Hangul/CJK/kana) and emoji 2
columns wide, so fenced mermaid blocks in assistant messages and
render_mermaid tool output had misaligned box borders for non-Latin
labels (upstream: lukilabs/beautiful-mermaid#119, #122).
Adds a patchedDependencies entry rebuilding the ASCII renderer to
measure terminal display columns: grapheme-cluster segmentation
(Intl.Segmenter), wcwidth-style policy (East Asian Wide + emoji
presentation + ZWJ/VS16/flag sequences = 2 columns; text-presentation
symbols like the renderer's own arrowheads stay narrow), and atomic
wide-glyph cell pairs so label collisions cannot shift row widths.
The patch modifies only existing files (bun cannot patch in new files,
and the exports "bun" condition loads src/ directly, so both src and
dist are patched). It mirrors the upstream PR and should be dropped
once the fix ships in a beautiful-mermaid release; a new CJK alignment
regression test keeps that transition honest.
Verified: bun test packages/coding-agent/test/modes/components/
assistant-message-mermaid.test.ts (8 pass, incl. new display-column
alignment regression test); bun test packages/utils (154 pass); Korean
flowchart renders with uniform display-column row widths through the
patched package.
- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
- Added asynchronous Kitty conversion for assistant tool images using `convertToPng`, keyed per tool-call entry with cached and in-flight tracking.
- Updated assistant image rendering to prefer converted PNGs for Kitty terminals while preserving existing behavior for other protocols.
- Added a unit test that verifies WebP tool images are converted and rendered as Kitty image output instead of the raw image/webp fallback.
