Vector Embed

Generate and store vector embeddings using the `ruvector` npm package.

When to use

Use this skill to embed text, code, or documents into 384-dimensional vectors for semantic search, similarity comparison, or clustering. ruvector uses ONNX all-MiniLM-L6-v2 with HNSW indexing (52,000+ inserts/sec, ~0.045ms search).

Steps

1. **Ensure ruvector@0.3.13 is available**:

   npm ls ruvector 2>/dev/null | grep '0.3.3' || npm install ruvector@0.3.13

ruvector 0.3.3 bundles the ONNX runtime; no add-on is needed. If `embed text` reports `ONNX WASM files not bundled`, an older ruvector (0.2.x) is being resolved — rerun with the pinned `npx -y ruvector@0.3.13`. 2. **Embed the input** (use the `text` subcommand, with text as a positional arg):

• Single string: `npx -y ruvector@0.3.13 embed text "your text here"`
• With output file: `npx -y ruvector@0.3.13 embed text "your text here" -o vec.json`
• For a file: read its content via the Read tool, then pass it as the positional argument.
• For batch: loop over files in shell — ruvector@0.3.13 has no built-in `--batch`/`--glob` flags.

3. **Adaptive (LoRA) variant**: `npx -y ruvector@0.3.13 embed text "..." --adaptive --domain code` 4. **Confirm** — report vector dimension (384), norm, and any output path written. 5. **Store metadata** in AgentDB if needed: `mcp__plugin_ruflo-core_ruflo__memory_store({ key: "embed-SOURCE", value: "VECTOR_METADATA", namespace: "vector-patterns" })`

MCP alternative

Register the MCP server once with the pinned version:

claude mcp add ruvector -- npx -y ruvector@0.3.13 mcp start

Then call MCP tools directly: `hooks_rag_context` (semantic context), `brain_search` (collective brain), `hooks_ast_analyze`, `hooks_route`.

Caveats

• The `embed --batch --glob` flags do **not** exist in ruvector@0.3.13. `embed text` accepts one text, `--stdin`, or `--input-file <path>` (keeps sensitive text off argv); call it per file.
• If embedding fails, run `npx -y ruvector@0.3.13 doctor` to diagnose.
