OpenCode

OpenCode-Supermemory is an OpenCode plugin that gives your AI persistent memory across sessions. Your agent remembers what you worked on — across sessions, across projects.

Get Your API Key

Create a Supermemory API key from the API Keys page, then add it to your shell profile so it persists across sessions:

  • macOS / Linux (zsh)
  echo 'export SUPERMEMORY_API_KEY="sm_..."' >> ~/.zshrc
  source ~/.zshrc
  • macOS / Linux (bash)
  echo 'export SUPERMEMORY_API_KEY="sm_..."' >> ~/.bashrc
  source ~/.bashrc
  • Windows (PowerShell)
  [System.Environment]::SetEnvironmentVariable("SUPERMEMORY_API_KEY", "sm_...", "User")

Restart your terminal after running this.

Install the Plugin

bunx opencode-supermemory@latest install

For LLM agents (non-interactive):

bunx opencode-supermemory@latest install --no-tui

Ensure your ~/.config/opencode/opencode.jsonc contains:

{
  "plugin": ["opencode-supermemory"]
}

How It Works

Once installed, the plugin runs automatically:

  • Context Injection — On session start, relevant memories are fetched and injected into the agent’s context. This includes user preferences, project knowledge, and past interactions.
  • Keyword Detection — Phrases like “remember” or “save this” trigger automatic storage.
  • Smart Compaction — At 80% context capacity, sessions are summarized and saved as memories.
  • Privacy Protection — Content within <private> tags never persists.

Memory Scopes

Scope Description
user Memories that persist across all projects
project Memories isolated to the current project (default)

Memory Types

Type Description
project-config Project configuration and setup details
architecture Codebase structure and design patterns
error-solution Problems encountered and their fixes
preference User preferences and coding style
learned-pattern Patterns discovered during sessions
conversation Important conversation context

Commands

/supermemory-init

Explore and index your codebase structure into memory:

/supermemory-init

Tools

The agent has access to a supermemory tool with these modes:

Mode Parameters Function
add content, type?, scope? Store information
search query, scope? Find relevant memories
profile query? View user preferences
list scope?, limit? Display stored items
forget memoryId, scope? Remove memory

Configuration

Create ~/.config/opencode/supermemory.jsonc:

{
  "apiKey": "sm_...",                        // Or use SUPERMEMORY_API_KEY env var
  "similarityThreshold": 0.6,                  // Minimum match score (0-1)
  "maxMemories": 5,                            // Memories per injection
  "maxProjectMemories": 10,                    // Project memory listings
  "maxProfileItems": 5,                        // Profile facts injected
  "injectProfile": true,                       // Include user preferences in context
  "containerTagPrefix": "opencode",         // Tag prefix for scoping
  "compactionThreshold": 0.80                   // Context usage ratio for summarization
}
