llm-wiki

claude

A second brain for Claude Code + Obsidian inspired by Karpathy's LLM Wiki gist. Turn any LLM CLI into a disciplined wiki maintainer: incrementally ingest sources into a persistent, interlinked markdown vault; update entity/concept/source pages; flag contradictions; maintain index and append-only log. Knowledge compounds instead of being re-derived by RAG on every query. Ships 3 sub-agents (wiki-ingestor, wiki-librarian, wiki-linter), 5 slash commands (/wiki-init, /wiki-ingest, /wiki-query, /wiki-lint, /wiki-log), 8 Python tools (stdlib only: init_vault, ingest_source, update_index, append_log, wiki_search BM25, lint_wiki, graph_analyzer, export_marp), 8 reference docs, full vault templates (CLAUDE.md, AGENTS.md, cursorrules, 5 page templates), and a worked example vault. Cross-tool compatible with Claude Code, Codex CLI, Cursor, Antigravity, OpenCode, and Gemini CLI.

taiwanmd

claude

Ask Taiwan.md anything about Taiwan and get source-backed answers instead of guesses — 860+ curated, citation-backed articles across 12 languages, served by a local MCP server with no API key. Includes the contributor-node skill, which turns a scheduled Claude Code run on your own machine into a working node: it picks one open task (a missing translation, a broken link, a metadata gap), does it, and opens a pull request. Merge always stays with a human.

exomem

Exomem: MCP server, ten skills, and capture/retrieve hooks in one install. Raw sources stay immutable, conclusions carry provenance, nothing is deleted - it is superseded.

Artexis10/exomem 9

Exomem is a living knowledge base for your AI assistants, not a dump of chat history. It preserves decisions, sources, evidence, relationships, plans, and useful conclusions as organised knowledge you can revisit, correct, and build on. As you work, Exomem helps your assistant bring relevant context forward, connect ideas, identify what has changed, and preserve lasting outcomes when your settings and assistant support it. Answers can point back to the notes and evidence behind them. Outdated information can be reviewed or superseded instead of silently piling up. Pick up projects in another conversation or across supported AI assistants connected to the same Exomem account. Exomem does not automatically import your past conversations or access arbitrary files on your device. Connect an existing Exomem account; registration, invitations, and billing are handled separately on the website.

fmflurry/code-memory 8

Skills and an MCP server for building on MapleStory Universe game data. The bundled maple-lookup MCP server searches the MSU Open API for characters, mobs, maps, skills, items, and sprites; the skills cover how that data is structured, how to choose between candidates, and how to turn it into something that renders. This plugin owns the MSU Builder OpenAPI key, and other NEXPACE plugins build on it instead of copying its skills.
