Use Open Second Brain to read, write, and maintain an agent-owned second brain in an Obsidian-compatible Markdown vault. The agent owns one top-level directory (`Brain/`). User-authored notes live wherever the operator names them and are read-only inputs when listed in `notes.read_paths`.
Use when the user explicitly mentions codegraph, asks structural code questions such as callers/callees/impact, asks where a symbol is defined, asks what breaks if a symbol changes, or asks for an architectural overview of a code repository. Skip for prose-only or vault-only questions.
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.
Append-only operational event logging for Open Second Brain. Daily Markdown notes are the default backend. INVOKE this skill (and call `event_log_append`) immediately after producing any durable artifact in the current turn — code shipped, bug fixed, refactor merged, config or deployment change, instruction-file edit (CLAUDE.md / AGENTS.md / plugin docs / system prompts), content artifact created (post, draft, documentation, marketing copy, release notes), research or investigation that produced a concrete finding or decision worth recalling later, or discovery of an external fact (CLI behaviour change, API quirk, undocumented edge case) that future sessions should know. SKIP for pure discussion, exploration, read-only queries, and planning that has not yet produced an artifact. If unsure, ask "would future-me want to find this in the log by searching for it later?" — if yes, log it. WRITE the `message` in the same natural language the user has been speaking with you in this session — never default to English

Use this skill when a task changes the active Brain schema pack in Brain/_brain.yaml or reviews content against that schema.
schema_inspect (view="active_pack") or o2b brain schema --json.schema_inspect views stats, lint, and orphans.schema_inspect (view="explain_type") before renaming or deleting them.schema_apply_mutations or o2b brain schema apply --mutation ... so writes are locked, atomic, and audited.Supported operations are add_type, remove_type, update_type, add_alias, remove_alias, add_prefix, remove_prefix, add_link_type, remove_link_type, set_extractable, and set_expert_routing.
Schema tokens must be lowercase normalized tokens accepted by Open Second Brain schema validation. Prefer small, durable tokens over project-specific phrasing unless the schema pack is explicitly project-scoped.
