OpenYOLO

OpenYOLO

English | 中文

OpenYOLO is an AI note assistant plugin for Obsidian (desktop only). The plugin itself contains no agent or model implementation — instead, it connects to opencode as its backend via the Agent Client Protocol (ACP), and provides a chat interface in the sidebar. Model access, tool execution, session history and memory are all maintained natively by opencode.

Features

• Chat: streaming output, collapsible reasoning, tool-call cards (read/write/edit/terminal/search, with diff preview for edits), and a structured todo panel above the composer
• Subagents: completed task results stay in their original tool cards and are collapsed by default; expand a card to inspect the inline output
• Context awareness: can automatically attach the currently open note (configurable); attach multiple vault notes via the attachment panel, or add external text files / images (paste supported)
• Permission approvals: tool permission requests shown as cards (allow once / always allow / reject); optional YOLO mode auto-approves everything
• Mode switching: plan (a restricted planning mode where file editing and command execution depend on your opencode permission configuration) / build, mapped to opencode session modes
• Model & effort selection: searchable list of all models configured in opencode; selections are persisted and restored across restarts (falls back to the first model if the saved one disappears)
• Slash commands: type / to invoke opencode commands / skills
• History: automatically restores the most recent session; browse all persisted sessions
• Conversation save & restore (lightweight): a save button in the header manually exports the current conversation (user/assistant text only) to a vault note — no real-time sync, each save overwrites the same file for the same session. Notes are grouped under a configurable folder (default YOLO/<YYYY-MM-DD>/<title>.md), deduplicated by an embedded session-id marker. Saved notes appear alongside opencode sessions in the history list; picking one starts a new chat that automatically restores the context with a built-in prompt — useful for continuing a conversation on another device
• Note-assistant prompt: can maintain a managed block in the vault-root AGENTS.md to guide opencode toward note-centric work; this opt-in feature is disabled by default and its prompt is editable in settings

How it works

Obsidian plugin (ACP client)  ──stdio / JSON-RPC──▶  opencode acp (subprocess)

• Spawns opencode acp as a subprocess and communicates via the official @agentclientprotocol/sdk
• Sessions are persisted by opencode; the plugin replays history via session/list + session/load
• Attachments are sent as ACP resource_link blocks and read natively by opencode
• File access (fs/read_text_file / fs/write_text_file) is implemented through the vault adapter. It validates lexical and real paths, rejects symlinks that escape the vault, and revalidates parent directories before writes. This is still not a complete sandbox: opencode runs as a trusted local subprocess.
• AGENTS.md management is opt-in. When enabled, the plugin atomically updates only its marked block and preserves content outside that block.
• Permission requests (session/request_permission) are routed to in-plugin approval cards
• Conversation saves are plain Markdown notes with an openyolo-session metadata marker, so re-saving the same session overwrites its previous file even after the title changes; restoring embeds the note content directly in the prompt (no tool calls needed)
• The UI is a React-rendered ItemView; session/update notifications are mapped to immutable state for streaming rendering

Prerequisites

1. Install opencode: curl -fsSL https://opencode.ai/install | bash
2. Configure a model provider: opencode auth login
3. Desktop only (requires Node subprocess capability)

Installation

Copy manifest.json, main.js and styles.css into .obsidian/plugins/openyolo/ of your vault, then enable OpenYOLO in "Settings → Community plugins".

Development

npm install
npm run dev        # watch build
