claude-mem-opencode

OpenCode integration for claude-mem persistent memory.

Overview

claude-mem-opencode automatically captures your OpenCode coding sessions as compressed memories, making them searchable for future sessions. It provides persistent context across sessions with ~10x token efficiency compared to storing full tool outputs.

Requirements

- Node.js >= 18.0.0
- Bun >= 1.0.0
- claude-mem >= 8.5.4 (for full functionality)

Important Note

claude-mem v8.5.4 worker API is required for full functionality but is only available from GitHub releases, not npm.

See Installation Guide for detailed instructions on installing claude-mem from GitHub.

Features

- Automatic Memory Capture: Captures tool usage automatically via OpenCode events
- Intelligent Compression: Uses AI to compress observations while preserving context
- Natural Language Search: Search your coding history using natural language
- Privacy Protection: Automatic privacy tag stripping for sensitive data
- Session Mapping: Maps OpenCode sessions to claude-mem sessions
- Context Injection: Automatically injects relevant memories into new sessions

Quick Start

$3

``bash


Clone claude-mem repository

git clone https://github.com/thedotmack/claude-mem.git
cd claude-mem

Build and install

bun install
bun run build
bun link

Verify installation

claude-mem --version

Should output: 8.5.4

`

$3

`bash
claude-mem worker start

Verify worker is running


curl http://localhost:37777/api/health
`

$3

`typescript
import { ClaudeMemIntegration } from 'claude-mem-opencode'

const integration = new ClaudeMemIntegration()
await integration.initialize()

// Memory is now being captured automatically!
`

$3

`typescript
import { ClaudeMemIntegration } from 'claude-mem-opencode'

const integration = new ClaudeMemIntegration()
await integration.initialize()

// Memory is now being captured automatically!

// Search memories
const results = await integration.searchMemory("authentication")

// Get project context
const context = await integration.getProjectContext()

// Get status
const status = await integration.getStatus()
console.log(status)
`

Configuration

The plugin supports flexible configuration through multiple sources:

$3

1. Default values - Built-in defaults in the plugin
2. Environment variables - OPENCODE_CLAUDE_MEM_* prefix
3. Global config file - ~/.config/opencode/claude-mem.jsonc
4. Project config file - /.opencode/claude-mem.jsonc

$3

`bash


Environment variables

export OPENCODE_CLAUDE_MEM_WORKER_PORT=9999
export OPENCODE_CLAUDE_MEM_DEBUG=true

Global config file

mkdir -p ~/.config/opencode
cat > ~/.config/opencode/claude-mem.jsonc << 'EOF'
{
"workerPort": 9999,
"debug": true,
"maxContextMemories": 10
}
EOF

Project config file

mkdir -p .opencode
cat > .opencode/claude-mem.jsonc << 'EOF'
{
"enabled": false,
"autoInjectContext": false
}
EOF
`

$3

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| enabled | boolean | true | Enable/disable the plugin |
| workerPort | number | 37777 | Port where claude-mem worker is running |
| debug | boolean | false | Enable debug logging |
| autoInjectContext | boolean | true | Automatically inject context on first message |
| maxContextMemories | number | 5 | Maximum memories to inject per session |

For detailed configuration documentation, see Configuration Guide.

Known Issues and Limitations

$3

2. Project Name Extraction Edge Cases
- Severity: Low
- Impact: Nested paths return filename instead of directory name
- Details: Simple basename extraction doesn't walk directory tree
- Workaround: Use current directory (works correctly)
- Affected scenarios: Importing from non-current paths

3. Integration Tests Require OpenCode Runtime
- Severity: Informational
- Impact: Some test scenarios require OpenCode to actually load the plugin
- Details: Direct API testing completed successfully (11/11 tests passed)
- Affected: Context injection, tool hooks, event hooks
- Resolution: Tests will verify when plugin is loaded in OpenCode

$3

Worker Version: Requires claude-mem v8.5.4 or higher from GitHub releases
- Reason: npm package (v3.9.16) doesn't include worker API needed by this plugin
- Solution: Install from source or wait for npm update

Plugin Installation:
- Add to opencode.jsonc: {"plugin": ["claude-mem-opencode"]}
- Ensure claude-mem worker is running before starting OpenCode
- Verify plugin loads: Look for [CLAUDE_MEM] messages on startup

$3

| Issue | Solution |
|-------|----------|
| Plugin not loading | Check opencode.jsonc syntax, restart OpenCode |
| Worker not responding | Run claude-mem worker restart, check port 37777 |
| No context injected | Verify memories exist for project, check worker logs |
| Tool not available | Check plugin loaded, check for tool in OpenCode tool list |

import { WorkerClient } from 'claude-mem-opencode'

const client = new WorkerClient(37777)

// Check health
await client.healthCheck()

// Initialize session
await client.initSession({
contentSessionId: 'session-123',
project: 'my-project',
prompt: 'Initial prompt'
})

// Add observation
await client.addObservation({
sessionDbId: 1,
promptNumber: 1,
toolName: 'bash',
toolInput: { command: 'ls' },

cwd: '/home/user/project',
timestamp: Date.now()
})

// Complete session
await client.completeSession(1)

// Search
const results = await client.search('query', { limit: 10 })
`

$3

Listens to OpenCode events and captures tool usage.

`typescript
import { EventListeners } from 'claude-mem-opencode'

const listeners = new EventListeners(workerClient)
await listeners.initialize()
`

$3

Injects memory context into OpenCode sessions.

`typescript
import { ContextInjector } from 'claude-mem-opencode'

const injector = new ContextInjector(workerClient)
const context = await injector.injectContext('my-project')
`

$3

Maps OpenCode session IDs to claude-mem session IDs.

`typescript
import { SessionMapper } from 'claude-mem-opencode'

const mapper = new SessionMapper()

// Map sessions
mapper.mapOpenCodeToClaudeMem('opencode-session-123', 1)

// Get mapping
const claudeMemId = mapper.getClaudeMemSessionId('opencode-session-123')
`

$3

Removes privacy tags from content before storage.

`typescript
import { PrivacyTagStripper } from 'claude-mem-opencode'

const stripper = new PrivacyTagStripper()

const cleaned = stripper.strip('secret data')
// Returns: ' data'
`

$3

Extracts project name from directory paths.

`typescript
import { ProjectNameExtractor } from 'claude-mem-opencode'

const extractor = new ProjectNameExtractor()

const projectName = extractor.extract('/home/user/my-project')
// Returns: 'my-project'

const currentProject = extractor.getCurrentProject()
// Returns: name of current working directory
`

$3

Simple logging utility.

`typescript
import { Logger, LogLevel } from 'claude-mem-opencode'

const logger = new Logger('MY_APP')

logger.debug('Debug message')
logger.info('Info message')
logger.warn('Warning message')
logger.error('Error message')
`

Privacy Protection

Use privacy tags to prevent sensitive data from being stored:

`typescript
// This will not be stored
password = "secret123"

// This will not be stored
Previously injected context
`

The PrivacyTagStripper automatically removes these tags before storing data.
