What's Changed

• Added a first-class provider template for Cheaper Inference, an OpenAI-compatible gateway, to the /settings providers wizard. Selecting it fills in the base URL (https://api.cheaperinference.com/v1) so only an API key and a model name are needed, and the wizard can fetch the account's model list over the standard /models endpoint.
• Added a showAgentBashOutput preference (/settings → Behavior → Tool Results and Thinking). By default a completed card for a command the agent runs shows the command and its status, and the command output is not kept; with compact tool display on, the card collapses into a tally line. This preference shows the output on that card, whether compact tool display is on or off, and for failed commands too. Commands you type yourself (!command) always show their output and are unaffected.
• Publish a JSON Schema for agents.config.json as schemas/agents.config.schema.json. It is generated deterministically from the on-disk DiskConfig type (pnpm run generate:schema), ships with an Ajv validation suite plus a CI drift check, and enables editor autocompletion — either by dropping the $schema key into your config or by wiring up the schema via jsonValidation / a JSON Schema mapping in your editor.
• Added automatic session titles. A session keeps its opening prompt as the title, and when that prompt is too thin to be useful the agent generates a descriptive name once, after the first turn that ran a tool or the first follow-up message. Manual renames are never overwritten.

Titling runs in the ACP agent, so it applies to the VS Code extension and other ACP clients; the CLI keeps its heuristic title. It uses the session's own model by default - set sessions.titleModel / sessions.titleProvider to point it at a cheaper or local one, or sessions.smartTitles: false to turn it off. Pointing titleProvider at a different provider sends it the opening user turns and a summary of the tools that ran, which includes file paths and bash command strings.

Two things worth knowing: the tokens a title costs are billed by the provider but are not counted in /usage, since the call is made outside the conversation loop that builds usage records; and existing sessions are retitled from their first message on their next autosave, which is a one-time visible reshuffle of the history list.

Also fixed the CLI's autosave deriving the session title from the latest user message and rewriting it on every save, which overwrote titles in the store the VS Code extension reads from. Closes #808.

• Added Anthropic prompt caching. The system prompt, tool schemas, and conversation history are now marked with cache breakpoints, so multi-turn sessions read the stable prefix back out of cache instead of paying full price for it every turn. Cost reporting is cache-aware throughout: /usage and the per-response indicator price cache reads and writes at their own rates instead of billing every cache hit at the full input rate, and the per-response indicator surfaces the cached token count alongside the total. Opt out with "promptCaching": false on the provider config. Closes #888.
• Fix multi-line paste submitting the prompt partway through.

Nanocoder never enabled bracketed paste, so the terminal delivered a paste as bare bytes and the carriage return at each line break reached Ink's keypress parser as Enter. Pasting two lines sent the first line to the model and left the second in the input box. Paste handling relied entirely on heuristics (input rate, size, line count) that only ever saw text which had already made it into the buffer.

DECSET 2004 is now enabled in both screen modes. Paste payloads are lifted off stdin before Ink sees them and delivered to the input as a single event, so a pasted newline can no longer submit. The old heuristics remain as a fallback for terminals without bracketed paste support.

Fullscreen mode enables mouse reporting for wheel scrolling, which takes cli

What's Changed

• Added first-class provider template for Groq to the setup wizard.
• Added first-class provider template for OrcaRouter to the setup wizard.
• Added a /commit slash command that generates Conventional Commit messages from staged Git diffs using the active LLM client. Thanks to @DeepamJha. Closes #757.
• Consolidated upload actions under a single '+' menu in the VS Code webview to reduce UI clutter and improve scalability for future attachment types.
• Added context attachment functionality with UI for file/folder chips and drag-and-drop support.
• Added Settings Tab to the VS Code extension webview for configuring providers and behavior directly from the UI.
• list_directory no longer includes file sizes by default — they cost an lstat syscall per file plus output tokens for information that's rarely needed just to orient in a directory. Pass showSizes=true to opt back in, or use read_file with metadata_only=true for a single file's size.
• Added a per-response token usage and estimated cost indicator. Every assistant message in the CLI now ends with a subtle gray footer showing the provider-reported token count and estimated cost (e.g. Tokens: 4.2k | ~$0.01), computed from models.dev pricing; the cost segment is omitted for local/free models and the footer falls back to the previous client-side estimate when the provider reports no usage. The VS Code extension shows the same indicator under each finished response, fed by the per-turn usage now returned on the ACP prompt response. Note: the estimate prices all input tokens at the standard rate — cache read/write discounts are not factored in, so costs can be overstated for providers with prompt caching. Closes #756.
• Moved the rest of nanocoder's configuration into the /settings menu, so you can set things up without editing .json files by hand. Settings are grouped into Appearance, Input, Behavior, Providers, MCP, and Advanced tabs. New menu items let you set the default mode, auto-compact, sessions, reasoning traces, tool auto-approval, and a Web Search API key; view your configured providers and MCP servers before opening the setup wizards; open the Tune Model and Connect IDE wizards; and see the active NANOCODER_* environment variables. Advanced also includes an in-app JSON editor for agents.config.json: edit strings with the cursor inside the quotes, flip booleans with the arrow keys, and save atomically (a crash can't leave a half-written file).
• Sunset /setup-providers and /setup-mcp in favour of /settings. Both retired names still work for now — they open the matching /settings tab with a notice instead of erroring. /settings now takes a tab argument (/settings providers, /settings mcp), MCP has its own settings tab, and provider edits made from settings apply to the running session instead of waiting for the next launch. Selecting a provider or MCP server in settings now opens that entry's edit/delete choice directly, with a separate row for adding a new one.
• Added editor code lenses to the VS Code extension: every function, method, constructor and class now carries Explain Code and Generate Tests links, and clicking one reveals the chat view and sends that symbol - instruction, file:startLine-endLine and the source, fenced with the document language - as a prompt. Symbols come from the language server, so no per-language parsing is involved, and the lenses can be turned off with nanocoder.codeLens. Long symbols are capped before being inlined, so a lens click on a large class cannot spend a whole context window on one turn. Also fixes a pre-existing hang where sending a message while a tool approval was still pending left the composer spinning forever. Closes #750.
• Added @ mention autocomplete to the VS Code extension's chat composer: typing @ opens a floating dropdown of workspace files, folders and open editors, and selecting one attaches it as a context chip. Search runs on the extension host,

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 `s

What's Changed

• Added image attachments on user messages. Paste an image from the clipboard with Ctrl+V (via osascript on macOS, wl-paste/xclip on Linux, PowerShell on Windows), drag an image file into the terminal, or type a path - quoted, unquoted, and macOS backslash-escaped paths are all recognised, and http(s) URLs are left untouched. Attachments (PNG/JPEG/GIF/WebP, up to 10 MB) show above the input box and Ctrl+X removes the last one; references are stripped from the text and sent as image parts to vision-capable models. A missing clipboard tool now logs a debug breadcrumb instead of silently no-op'ing. Thanks to @ragini-pandey. Closes #572.

• Added skill promotion and demotion. Skills can now be promoted and demoted between project and personal scope, with a --move flag to relocate rather than copy the skill files.

• Fix: slash commands now run with their arguments. Once a space is typed after a slash command, the completion menu hides so Enter submits the full command with its arguments instead of selecting a completion and dropping everything after the command name.

• Fix: the chat view no longer snaps to the bottom when a slash command completion menu opens. The completion and file-suggestion menus now render inside the bounded input layout, so the container expands without disrupting the window height calculation that previously forced the history to scroll in smaller terminals. Thanks to @Dhirenderchoudhary. Closes #581.

• Fix: empty frontmatter blocks are recognised instead of leaking --- markers into the body or throwing. splitFrontmatter now matches an empty block, and extractRawFrontmatter uses the shared parseYamlObject helper so an empty subagent frontmatter flows through to validation and surfaces a clear name is required error. Thanks to @Fadhlan. Closes #592.

• Fix: ask_user unwraps label-as-key option objects, so options expressed as a { label: value } map render as readable choices.

• Fix: surface real network errors instead of mislabeling them as context overflow. A failed request from a network error is no longer misreported as exceeding the context window.

• Fix: size MoE models by total parameter count, not active count, when auto-resolving the tool profile, so mixture-of-experts models get the correct tune.

• Fix: number formatting on the /copy command output.

• Docs: clarified MCP tool profile visibility and documented the image-attachments feature. Thanks to @zerone0x. Closes #593.
