New
- Show read and edit paths relative to the session working directory in the transcript when the path is inside it.
- Group narration-free tool runs in the transcript with expandable read previews.
Changed
- Compact the TUI prompt and session info footer: top and bottom prompt rules, cwd and model with context usage on the footer lines.
- Replace the prompt activity indicator with a braille-dot spinner whose gap orbits the cell and whose accent color pulses.
- Cut TUI prompt-echo and startup latency: cache session index and transcript reads by file stamp, memoize catalog and git/skill-path lookups, run auto-naming and the update check off the startup path, and reserve submitted prompts so a fast second submit queues instead of cancelling.
- Reduce text input latency and CPU usage by coalescing streamed text appends, running full garbage collection when the agent settles, and keeping 80 transcript items mounted instead of 200.
- Tighten transcript spacing and omit whitespace-only blocks.
Fixed
- End a run as aborted instead of erroring when a cancel arrives during tool execution, keeping a hook's cancel reason as the error message.
- Name cut-off and missing tool call arguments in errors instead of reporting "path must be a string", and suggest sending less per call when arguments were cut off.
