Nanocoder v1.29.0 Release Notes — What's New

What's Changed

Added the ability to attach to a running subagent session from the terminal UI for interactive debugging. This feature allows users to inspect exactly what a subagent is doing in real-time, including streaming text and reasoning. You can press Ctrl+S while a subagent is running to attach to it, cycle between multiple running subagents, and press Esc to detach.
Added privacy-aware prompt scrubbing. A new PrivacyContext scrubs sensitive content from prompts before they leave your machine, with tool-argument rehydration and privacy session support, a /privacy command to inspect what is being scrubbed, and automated scrubbing telemetry notifications. Thanks to @akramcodez.
Added an interactive questions system for plan mode, so the agent can ask structured questions while planning instead of guessing. Thanks to @akramcodez. Closes #96.
Added mode-specific provider and model configuration, so each development mode can use its own provider and model. Thanks to @akramcodez. Closes #277.
Added dual TUI screen modes, with a more reliable /clear and graceful exit handling. Thanks to @llupRisinglll.
Added multiline cursor navigation and word-jump in the input box. Thanks to @llupRisinglll.
Added --resume / --continue CLI session flags. --continue (-c) resumes the most recent session for the current directory, and --resume [id] (-r) resumes a session by id, list index, or last, with a bare --resume opening the session picker at startup. Thanks to @llupRisinglll.
Added a fuzzy search filter to the /model picker, with a capped, centered scrolling window so large model catalogs no longer overflow the terminal and the current model is preselected. Thanks to @rakshith1928. Closes #683.
Added PDF and DOCX support to read_file via get-md, so those documents can be read directly. Thanks to @akramcodez.
Added a doctor diagnostic command that checks your setup and reports common configuration problems. Thanks to @Dhirenderchoudhary. Closes #609.
Added a retry command to re-run the last user turn. Thanks to @Dhirenderchoudhary. Closes #608.
Added message queueing while the agent is busy so you can type ahead. Queued messages can be recalled before streaming, are truncated properly on narrow terminals, and no longer double-dispatch. Thanks to @Dhirenderchoudhary. Closes #597, #598.
Added estimated dollar cost tracking to /usage, with a per-provider cost breakdown and a cumulative per-call cost history. Thanks to @rakshith1928. Closes #602.
Added a --json output flag to the non-interactive plain run path. Thanks to @OMEE-Y.
Added a diff_edit tool for nano-profile models. Thanks to @Dhirenderchoudhary. Closes #604.
Added automatic diagnostics after file edits, surfacing errors introduced by an edit right away. Thanks to @2409324124. Closes #538.
Added the foundation for semantic memory (storage layer and initial wiring), groundwork for upcoming memory features. Thanks to @Dhirenderchoudhary.
Reworked the client to a stateless API with history-boundary rehydration, improving conversation reliability. Thanks to @akramcodez.
Added a Together AI provider template and docs, and MiniMax Coding now defaults to MiniMax-M3. Thanks to @octo-patch. Added Atomic Chat local provider configuration docs. Thanks to @yanalialiuk.
Fix: nanocoder.tune loading and configuration precedence from agents.config.json now resolve correctly. Thanks to @rakshith1928. Closes #648.
Fix: patch malformed SSE termination strings from providers, preventing stream parsing errors. Thanks to @akramcodez. Closes #614.
Fix: bound slash command completions so the menu no longer overflows. Thanks to @2409324124. Closes #624.
Fix: decouple console log verbosity from NODE_ENV and quiet noisy LSP discovery logs. Thanks to @A-S-Manoj. Closes #606.
Fix: removed the strip-ansi runtime dependency. Thanks to @2409324124. Closes #643.
Docs: added a Simplified Chinese README and Traditional Chinese translations, with fixes to the Simplified Chinese copy, plus a star-history chart. Thanks to @2409324124, @jason1015-coder, and @zerone0x.
Updated dependencies: @ai-sdk/google, @ai-sdk/openai-compatible, undici, diff, and knip.
The VS Code extension saw major work this cycle (ACP process manager and handshake, a chat sidebar webview with tool-permission and diff UI, session persistence, and Tailwind styling). It is versioned separately from the CLI. Thanks to @akramcodez and @Dhirenderchoudhary.
File tools now resolve relative paths against the shell's current working directory, and cd in bash persists across commands — so relative reads and edits work after moving into a subdirectory or worktree. File tools also accept absolute paths that point inside the project, and can still reach the project root or a sibling worktree after cd-ing into a subdirectory.
Added a tabbed /settings dialog with searchable categories, so settings are easier to scan and filter from the TUI. Thanks to @llupRisinglll. Closes #471.
Added a native VS Code GUI. The VS Code extension now ships a sidebar chat powered by the Agent Client Protocol (ACP): the extension spawns and manages nanocoder --acp itself - nothing to run in a terminal. Responses stream with collapsible thinking sections, tool activity renders as live cards, and file edits open in VS Code's diff viewer. Thanks to @akramcodez.
Sessions in the GUI: conversations persist to disk, with a New Chat action, a session history view with resume and delete, and full thread replay (including thinking and completed tool cards) on resume.
Provider, model, and mode switching from dropdowns in the chat header, with the model list refreshing on provider switch.
Slash commands in the GUI: /help, /clear, and custom commands from .nanocoder/commands; CLI-only commands explain themselves, and messages starting with file paths are not mistaken for commands.
Interactive tools in the GUI: ask_user questions render with one button per answer; tool approvals show Approve/Deny inline.
Live progress: subagent runs stream token/tool counts onto their card, and the task tool (write_tasks) renders as a live checklist via ACP plan updates - which also lights up in other ACP clients like Zed.
Cancellation: Stop ends the whole turn - the current tool aborts, queued tools are skipped, and no follow-up model request is issued.
Robust CLI spawning: the extension resolves the login shell's PATH (nvm-friendly when VS Code launches from the Dock), runs the CLI in the workspace folder, validates nanocoder.cliPath, and surfaces the last stderr line in the crash dialog. Fixed a silent --acp startup crash when the working directory was unwritable.
Legacy WebSocket companion mode is now opt-in (nanocoder.autoConnect defaults to off); extension docs rewritten around the GUI.
Fixed static vs. live content misalignment in --alt-screen
