embeddings-setup SKILL.md skillB
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
embeddings-setup from itechmeat/open-second-brain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Bring Open Second Brain semantic search online — embedding API key, sqlite-vec extension, first reindex, optional periodic refresh. INVOKE when the user mentions "embeddings", "semantic search", "vector index", or after `o2b search check` reports `vec_extension: unavailable`, `embedding_key: missing`, or any line in its `recommendations:` block. SKIP when the user is asking conceptual questions about embeddings or comparing providers without intent to set up — answer those directly.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Embeddings setup Open Second Brain ships with two search paths: keyword-only (always on, no credentials) and semantic via embedded vectors (opt-in). This SKILL walks the activation flow for the semantic path. The flow is proactive — when the user mentions semantic search or `o2b search check` surfaces missing pieces, take the user through this list rather than waiting for explicit instruction. ## Step 1 — Always start with `o2b search check` ```bash o2b search check ``` The output names every missing piece and ends with a `recommendations:` block listing the exact commands to fix each. Read both before suggesting next steps. The `recommendations` field is also present in the `--json` output for headless callers. Branch on what the report shows: - `embedding_key: MISSING` → go to step 2. The `key_sources_checked:` line names where the key was looked for, and `key_present_under:` names any other registered provider profile whose env key is set. If the key sits under another profile, the fix may be pointing `embedding_provider` at that profile rather than adding a key. - A recommendation saying the embedding model has no known price, or …

How to install
mdr add itechmeat/open-second-brain/embeddings-setup@sha256:7571f79221b11be4The line at the top of this page pins the label git:20261006.0f0c9a7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
