# opencode-config

Docker-based AI coding assistant with persistent memory — opencode configuration.

## Quick start

### Docker

```bash
git clone https://github.com/slaid098/opencode-config.git
cd opencode-config
cp .env.example .env  # fill in your keys
docker compose up -d
```

Access at http://localhost:4096.

### Bare (without Docker)

```bash
git clone https://github.com/slaid098/opencode-config.git
cd opencode-config
opencode  # .opencode/ auto-discovered
```

## Structure

- `AGENTS.md` — global orchestrator rules (main agent = plan only, all via subagents)
- `.opencode/` — project-local config (auto-discovered, zero env var)
  - `agents/` — subagent definitions (docs-reviewer, memory-syncer, reviewer)
  - `commands/` — slash commands (run-pipeline, spec, configure-opencode)
  - `skills/` — skill definitions (14 skills)
  - `tools/` — custom tools (commit, create-issue, create-pr, memory-setup, merge-pr, pipeline-status, post-docs-review, post-review, spec-status, tunnel)
  - `scripts/` — Python scripts (pipeline-status, spec-status, check-adr-refs, etc.)
  - `opencode.json` — main config (providers, MCP servers, permissions)
- `app_data/workspaces/` — agent working directory
- `app_data/ssh/` — SSH keys (not in git)
- `src/` — Python RAG CLI (memory)
- `docs/` — handoffs, decisions (ADRs), project map
- `.github/workflows/` — CI workflows (ubuntu-latest)

## Configuration

Copy `.env.example` to `.env` and fill in:

| Variable | Description |
|----------|-------------|
| `AI_PROVIDER_BASE_URL` | AI provider API URL |
| `AI_PROVIDER_API_KEY` | AI provider API key |
| `OPENAI_BASE_URL` | Embeddings API URL (OpenRouter default) |
| `OPENAI_API_KEY` | Embeddings API key (OpenRouter) |
| `OPENAI_EMBEDDING_MODEL` | Embedding model (default: `qwen/qwen3-embedding-8b`) |
| `OPENAI_EMBEDDING_BATCH_SIZE` | Embedding batch size (default: 50) |
| `OPENCODE_SERVER_PASSWORD` | opencode server password |
| `GITHUB_TOKEN` | GitHub personal access token |
| `CONTEXT7_API_KEY` | Context7 MCP API key |
| `OPENCODE_MEMORY_REMOTE` | Git remote for your opencode-memory fork (required) |
| `MEMORY_CHUNK_SIZE` | Memory index chunk size (default: 512) |
| `MEMORY_CHUNK_OVERLAP` | Memory index chunk overlap (default: 64) |
| `ANTIDETECT_BROWSER_MCP_URL` | Antidetect browser MCP URL (optional) |

## Memory setup

Memory uses `@mathew-cf/opencode-memory` plugin — hybrid search: ripgrep (keyword) + cloud embeddings (OpenRouter Qwen3 8B, 4096 dim, $0.01/M tokens).

### How it works

```
opencode (plugin) → rag.js wrapper → python3 -m src.memory → OpenRouter API
                                  ↘ ripgrep (keyword search, parallel)
```

- `memory_search` runs both paths in parallel, merges results by score
- `memory_save` commits to memory repo, post-commit hook auto-pushes, then incremental reindex (only changed file, ~1 sec)
- First full reindex: ~4 min for 78 files / 2379 chunks via OpenRouter
- Index format: `.rag/index.json` (embeddings) + `.rag/meta.json` (SHA256 + version) + `.rag/.lock` (flock)

### Prerequisites

1. **Fork the memory repo**: fork [`slaid098/opencode-memory`](https://github.com/slaid098/opencode-memory) to your GitHub account
2. **Get OpenRouter API key**: sign up at [openrouter.ai](https://openrouter.ai), create API key (Qwen3 8B = $0.01/M tokens; $9 balance ≈ 700K incremental saves)
3. **Fill `.env`** (see [Configuration](#configuration) table above):
   ```
   OPENAI_BASE_URL=https://openrouter.ai/api/v1
   OPENAI_API_KEY=sk-or-v1-...
   OPENAI_EMBEDDING_MODEL=qwen/qwen3-embedding-8b
   OPENAI_EMBEDDING_BATCH_SIZE=50
   OPENCODE_MEMORY_REMOTE=https://github.com/<your-username>/opencode-memory.git
   OPENCODE_MEMORY_DIR=/root/.local/share/opencode/opencode-memory
   GITHUB_TOKEN=ghp_...
   ```

### Initialize

#### In Docker (recommended)

```bash
git clone https://github.com/slaid098/opencode-config.git
cd opencode-config
cp .env.example .env  # fill in keys (see Prerequisites)
docker compose up -d
```

Memory initializes automatically on first container start (via `memory-setup` tool). To re-run manually:

```bash
docker exec opencode bash -c "cd /root/workspace/opencode-config && .opencode/scripts/setup-memory.sh"
```

#### Bare metal

```bash
git clone https://github.com/slaid098/opencode-config.git
cd opencode-config
uv sync  # install Python deps
cp .env.example .env  # fill in keys
.opencode/scripts/setup-memory.sh
```

### setup-memory.sh steps

The script is idempotent — safe to re-run:

1. Create `OPENCODE_MEMORY_DIR` if missing
2. Clone memory repo (or `pull --ff-only` if exists)
3. Verify remote origin matches `OPENCODE_MEMORY_REMOTE`
4. Install post-commit hook (auto-push on `memory_save`)
5. Build RAG index if `.rag/index.json` missing (full reindex via OpenRouter, ~4 min)
6. Generate JS wrapper at `node_modules/@mathew-cf/rag-cli/bin/rag.js` (delegates to Python CLI; original backed up to `.orig`)

### Verify it works

```bash
# Wrapper should be Python shim (~10 lines), not Rust binary (71 lines)
cat node_modules/@mathew-cf/rag-cli/bin/rag.js

# Meta should show our format (version + sha256), not Rust (model_id + hidden_size)
cat $OPENCODE_MEMORY_DIR/.rag/meta.json | python3 -m json.tool | head -5

# .rag/ should contain index.json + meta.json + .lock (no index.bin)
ls -la $OPENCODE_MEMORY_DIR/.rag/

# Search end-to-end (through wrapper, as plugin does)
node node_modules/@mathew-cf/rag-cli/bin/rag.js search "docker compose bind mount" \
  -i $OPENCODE_MEMORY_DIR/.rag -k 3 --json
```

### Troubleshooting

| Symptom | Cause | Fix |
|---------|-------|-----|
| `Semantic search is unavailable` in opencode | Wrapper not generated or rag-cli not installed | Re-run `setup-memory.sh` |
| Search returns results but no scores | Using Rust rag-cli (old wrapper) | Check `rag.js` is Python shim (10 lines); re-run `setup-memory.sh` |
| `Index version mismatch, full reindex` on every run | meta.json missing or stale | Delete `.rag/` and re-run `setup-memory.sh` |
| `OPENAI_BASE_URL env var not set` | .env not loaded | For Docker: `docker compose up -d --force-recreate`; for bare: ensure `.env` in CWD |
| 429 rate limit from OpenRouter | Batch too large or too fast | Reduce `OPENAI_EMBEDDING_BATCH_SIZE` (default 50, max 100 for OpenRouter) |
| Stale Rust artifacts (`index.bin` in `.rag/`) | Migrating from old rag-cli | `rm -rf $OPENCODE_MEMORY_DIR/.rag/` then re-run `setup-memory.sh` |

### Environment variables

| Variable | Default | Description |
|----------|---------|-------------|
| `OPENCODE_MEMORY_DIR` | `/root/.local/share/opencode/opencode-memory` | Memory repo location |
| `OPENCODE_MEMORY_REMOTE` | — (required) | Git remote for your opencode-memory fork |
| `OPENAI_BASE_URL` | — (required) | Embeddings API URL (OpenRouter: `https://openrouter.ai/api/v1`) |
| `OPENAI_API_KEY` | — (required) | OpenRouter API key |
| `OPENAI_EMBEDDING_MODEL` | `qwen/qwen3-embedding-8b` | Embedding model (4096 dim) |
| `OPENAI_EMBEDDING_BATCH_SIZE` | `50` | Chunks per API call (OpenRouter max 100) |
| `MEMORY_CHUNK_SIZE` | `512` | Chunk size in characters |
| `MEMORY_CHUNK_OVERLAP` | `64` | Overlap between chunks |
| `MEMORY_WRAPPER_PATH` | (auto-detected) | Override rag.js wrapper path (for tests) |
| `MEMORY_WRAPPER_PYTHON` | (auto-detected) | Override Python binary for wrapper (for tests) |
