v2026.7.20

Breaking Changes

• Replaced the snapshot-style todowrite/todoread pair with one phased, op-based todo tool; the todowrite builtin extension id remains for loader compatibility.

Added

• Added a /todo command for user-side todo management: view, overlay edit (Markdown checklist), copy, export/import (default TODO.md), and fuzzy-matched append/start/done/drop/rm; user edits persist as senpi.todo-state entries and notify the agent next turn.
• Added antml as a valid compat.toolCallFormat in custom models.json provider and model definitions: ANTML <function_calls>/<invoke> text-tool protocol with Claude-Code-style failure tolerance.
• Added built-in llama.cpp router support with /login connection setup and /llama Hugging Face model search and downloads, explicit loading, unloading, and live progress. See llama.cpp.
• Added extension registration for complete pi-ai providers, including native authentication, model refresh, filtering, and streaming behavior.

Changed

Fixed

• Fixed Kimi Coding sessions to show API-equivalent implied costs with the subscription indicator.
• Fixed OpenAI Responses early stream endings to trigger automatic retry instead of ending the agent run (#6727).
