Release notes

Nanocoder v1.23.0

What's Changed

  • Added ask_user tool for interactive question prompts. The LLM can now present the user with a question and selectable options during a conversation, returning their answer to guide the next step. Uses a global question-queue to bridge the tool's suspended Promise with the Ink UI component.

  • Added per-project cron scheduler for running AI tasks on a schedule. Schedule files live in .nanocoder/schedules/ as markdown prompts with YAML frontmatter, managed via the /schedule command (create, add, remove, list, logs, start). Includes cron expression parsing, sequential job queue with deduplication, dedicated scheduler mode with auto-accept, and run history logging.

  • Added centralized graceful shutdown system. A ShutdownManager now coordinates cleanup of all services (VS Code server, MCP client, LSP manager, health monitor, logger) on exit, preventing orphaned child processes and dangling connections. Configurable via NANOCODER_DEFAULT_SHUTDOWN_TIMEOUT env variable. Closes #239.

  • Added file operation tools: delete_file, move_file, create_directory, and copy_file. Reorganized existing file tools into a file-ops/ directory group.

  • Added readline keybind support to text input. Replaces ink-text-input with a custom TextInput component supporting Ctrl+W (delete word), Ctrl+U (kill to start), Ctrl+K (kill to end), Ctrl+A/E (jump to start/end), and Ctrl+B/F (move char). Closes #354.

  • Added /context-max command and NANOCODER_CONTEXT_LIMIT env variable for manual context length override on models not listed on models.dev. Resolution order: session override > env variable > models.dev > null. Closes #379.

  • Added /ide command matching the --vscode flag for toggling VS Code integration from within a session.

  • Added persistent context percentage display in the mode indicator, replacing the previous context checker component.

  • Added include and path parameters to search_file_contents tool for scoping searches to specific file patterns and directories.

  • Added Kanagawa theme.

  • Refactored the skills system into custom commands, eliminating redundant parsers, loaders, and test suites. Commands gain optional skill-like fields (tags, triggers, estimated-tokens, resources) for auto-injection and relevance scoring. The /skills command is removed and its functionality absorbed into /commands with new subcommands (show, refresh). Thanks to @yashksaini-coder for the initial skills implementation in PR #370.

  • V2 type-safe tool system overhaul with defensive parsing. Implements a three-tiered defense system for handling chaotic LLM outputs, preventing crashes from non-string responses and enabling robust self-correction. Includes universal type safety with ensureString(), response normalization, confidence system inversion, ghost echo deduplication, and AI SDK contract fixes. Local LLM experience is now significantly more stable. Thanks to @cleyesode. Closes #362.

  • Fix: XML parser now uses optimistic matching for consistency with the JSON parser. Thanks to @cleyesode.

  • Fix: Bash tool now emits progress immediately on stdout/stderr data instead of waiting for the 500ms timer, so fast-completing commands show streaming output.

  • Fix: Recognize 127.0.0.1 as a local server URL and tighten error classification. Ollama users configuring 127.0.0.1 instead of localhost no longer experience misleading connection errors. Replaced broad connect substring match with specific error codes to prevent misclassifying "disconnect"/"reconnect". Closes #366.

  • Fix: Skip loading git tools when not inside a git repository.

  • Fix: Strip ANSI escape codes before running regex matching in tool formatters.

  • Fix: Gap in layout during auto-compact.

  • Fix: Hardened write_file validation and MCP client type safety.

  • Fix: Use local TextInput component instead of the missing ink-text-input package.

  • Fix(mcp): Use Python-based mcp-server-fetch instead of non-existent npm package.

  • Security: Semgrep and audit fixes.

  • Dependency updates: ai 6.0.95, @ai-sdk/anthropic 3.0.46, @ai-sdk/google 3.0.30, undici 7.22.0, sonic-boom 4.2.1.
