Build and maintain a persistent Obsidian knowledge bank as a second brain for Claude Code: auto-document sessions with workflows and decisions on recap triggers, ingest external sources through interactive discussions, query insights via subagents prioritizing reflections, lint for broken links and staleness, and manage session metadata.
npx claudepluginhub sxhmilyoyo/sundayhao-plugins --plugin second-brainIngest external sources (articles, gists, docs, URLs) into the knowledge bank through interactive discussion. Follows the LLM Wiki pattern — READ source, DISCUSS key takeaways with user, CREATE wiki pages, INTEGRATE into existing knowledge. Triggers on "ingest this", "add to knowledge bank", "process this article", or when user provides external reference material for long-term retention.
Health-check the knowledge bank for orphan documents, stale content, broken WikiLinks, index drift, and missing frontmatter. Generates a severity-graded report. Use this skill whenever the user mentions lint, health check, KB maintenance, stale docs, broken links, orphan pages, missing references, knowledge bank quality, or hasn't run a check in a while. Also trigger when the user asks "what's not cross-referenced?", "are there any dead links?", or expresses concern about KB quality.
Delegates knowledge bank lookups to Explore subagents with reflections-first strategy that learns from past mistakes. Checks /reflections/ directory before documentation to extract documented failures to avoid and proven approaches to apply. Automatically triggers when user mentions services ([project-a], [project-b], [project-c], Claude Code), requests investigations, or queries past lessons. Returns structured, actionable insights achieving 69-94% context reduction. (project, gitignored)
Manage current Claude Code session metadata — set project, tags, and summary on session.md via Obsidian CLI. Use this skill whenever the user wants to tag, categorize, name, label, summarize, or organize the current session. Triggers on phrases like "tag this session", "this was about X", "mark this as", "session summary", "call this session", "categorize this as", "set project to", or any mention of session metadata or session organization. Even if the user just casually mentions what the session was about ("we were working on the auth refactor"), use this skill to offer to set tags.
Document Claude Code sessions by extracting knowledge into cross-referenced documentation. Triggers on "recap the session", "summarize the work", or after significant code changes.
