Commands Reference

Type / in the chat input to see available commands. All commands start with / and can be invoked at any point during a session.

Built-in Commands

Command Description
/help Show available commands
/init Initialize project with intelligent analysis, create AGENTS.md and configuration files. Use /init --force to regenerate AGENTS.md if it already exists, or /init --lean to skip merging CLAUDE.md content into the generated AGENTS.md
/setup-providers Interactive wizard for configuring AI providers with templates
/setup-mcp Interactive wizard for configuring MCP servers with templates
/setup-config Open a configuration file in your $EDITOR (lists project and global config files)
/clear Clear chat history
/model Switch between available models from any configured provider
/status Display current status (CWD, provider, model, theme, available updates, AGENTS setup)
/tasks Manage task list for tracking complex work (see Task Management)
/model-database Browse coding models from OpenRouter (searchable, filterable by open/proprietary)
/settings Interactive menu to access Nanocoder settings (theme, title-shape, nanocoder-shape, paste-threshold)
/mcp Show connected MCP servers and their tools
/custom-commands List all custom commands
/checkpoint Save and restore conversation snapshots (see Checkpointing)
/compact Compress message history to reduce context usage (see Context Compression)
/context-max Set maximum context length for the current session, or inspect the resolved context source. Also available as --context-max CLI flag
/exit Exit the application
/export Export current session to markdown file
/copy Copy the last assistant response to the system clipboard
/doctor Show environment health report for bug reports
/update Update Nanocoder to the latest version
/usage Get current model context usage visually
/lsp List connected LSP servers
/schedule Read-only view of cron subscriptions declared by skills (see Skills → Event subscriptions)
/skills List and inspect loaded skills; scaffold new bundle skills with AI assistance (see Skills)
/resume Resume a previous chat session (aliases: /sessions, /history). Also available at launch via the --resume/--continue CLI flags. See Session Management
/retry Re-run the last user turn. Use /retry --model <id> or /retry --provider <name> --model <id> to switch models first
/rename Rename the current session. Name must be non-empty and 100 characters or less. See Session Management
/explorer Interactive file browser to navigate, preview, and select files for context
/tune Configure runtime model behaviour — tool profiles, compaction, native tools, model parameters (see Tune)
/ide Connect to an IDE for live integration (e.g., VS Code diff previews)

Special Input Syntax

These shortcuts work directly in the chat input — no / prefix needed.

Syntax Description
!command Execute bash commands directly without leaving Nanocoder (output becomes context for the LLM)
@file Include file contents in messages via fuzzy search — press Tab to select from suggestions
@file:10-20 Include specific line range from a file (line 10 to 20)
@file:10 Include a single line from a file

File Mentions

The @ syntax triggers real-time fuzzy matching as you type. Nanocoder searches your project files (respecting .gitignore) and shows autocomplete suggestions. Press Tab to accept a suggestion.

You can narrow the context by specifying line ranges:

What does this function do? @src/utils.ts:45-80
Explain the error on @src/app.tsx:23

Shell Commands

The ! prefix runs a command in your shell and includes the output as context for the AI:

!git log --oneline -10
!npm test -- --filter auth

Non-Interactive Mode

Run Nanocoder without an interactive session for scripting and automation:

nanocoder run "Add error handling to src/api.ts"

This submits the prompt and exits when complete. Useful for CI pipelines, git hooks, or chaining with other tools.

Run mode renders through a dedicated minimal shell: no welcome banner, no boxed "You:" echo, no trailing token counts, no ctrl+r to expand hints. Assistant text streams as plain markdown, tools render chronologically as one-liners (e.g. ⚒ Read 1 file), and a single status line below the transcript shows progress.

By default, run uses auto-accept. Override with --mode to boot into a different development mode:

# Plan only — no changes executed
nanocoder --mode plan run "analyze the auth module"

# No safety rails — auto-accepts every tool including bash
nanocoder --mode yolo run "update README and push"

If a tool requires approval that the active mode won't grant, nanocoder prints Tool approval required for: ... and exits with status code 1.

JSON Output

For CI pipelines, scripting, and tool chaining, pass --json (alias --output-format json) alongside run to get a single structured JSON object on stdout instead of streamed markdown:

nanocoder --plain --json run "Add error handling to src/api.ts"

With --json set, all human-readable output — boot banners, streamed tokens, tool one-liners, status lines — is suppressed from stdout. Anything nanocoder would otherwise print is instead routed to stderr, so stdout stays clean for piping:

nanocoder --plain --json run "refactor the auth module" | jq .finalText

--json requires run and is incompatible with --acp and --vscode — combining them exits with an error before the session starts.

Output Shape

The emitted object looks like:

{
  "outcome": "success",
  "finalText": "...",
  "reasoning": "...",
  "toolCalls": [
    {
      "name": "edit_file",
      "arguments": { "path": "src/api.ts" },
      "result": "...",
      "error": null
    }
  ],
  "modifiedFiles": ["src/api.ts"]
}
  • outcome — "success", "tool-approval-required", or "error", matching the underlying conversation result
  • finalText — the model's final response text
  • reasoning — accumulated reasoning/thinking content, or null if the model didn't emit any
  • toolCalls — every tool call made during the run, each with its arguments and either a result or an error (never both)
  • modifiedFiles — deduplicated list of file paths touched by file-mutating tools (write_to_file, create_file, string_replace, edit_file)

On error (e.g. an untrusted workspace directory, or the turn limit being hit without a final answer), outcome is "error" and the object still includes whatever toolCalls were captured before the failure, so partial progress isn't silently dropped.
