OpenCode plugin for memelord -- persistent memory for coding agents.
Gives your OpenCode agent persistent memory that improves over time. The plugin provides everything out of the box:
Memory tools (replaces the MCP server):
| Tool | Purpose |
|---|---|
memory_start_task |
Retrieve relevant memories via vector search at the start of every task |
memory_report |
Store corrections, user inputs, or codebase insights |
memory_end_task |
Rate retrieved memories and record task outcome |
memory_contradict |
Flag an incorrect memory and delete it |
memory_status |
Show memory system stats |
Lifecycle hooks (automatic, no agent action needed):
| OpenCode event | Purpose |
|---|---|
session.created |
Inject top memories into context |
tool.execute.after |
Record tool failures for pattern detection |
session.idle |
Analyze transcript for self-corrections and discoveries |
session.deleted |
Embed pending memories, run weight decay |
Add to your global OpenCode config (~/.config/opencode/opencode.json):
{
"plugin": ["opencode-memelord@latest"]
}That's it. OpenCode auto-installs the plugin and all dependencies at startup.
- Global database -- memories are stored at
~/.config/memelord/projects/<project>/memory.db, keyed by git remote URL. Multiple worktrees of the same repo share the same database. - Local embeddings -- uses
Xenova/all-MiniLM-L6-v2(384-dim, quantized, runs on CPU) via@huggingface/transformers. No API keys needed. The model is lazy-loaded on first use. - Uses the memelord SDK directly -- same memory lifecycle, scoring, and decay algorithms. Same analysis logic for detecting self-corrections, discoveries, and failure patterns.
- Session starts -- top memories by weight are injected into context
- Agent works -- tool failures are tracked automatically
- Agent finishes responding -- transcript is analyzed for self-corrections (failed tool -> same tool succeeds with different input) and discoveries (high-token exploration sessions)
- Session ends -- new memories are embedded and weight decay runs
Memories that consistently help survive. Memories that don't get garbage collected over time.
