commonplace
Builds and maintains a cited markdown research wiki and second brain ("commonplace") while doing research, studying, or working on projects. Keeps every original document, a faithful page-anchored markdown copy and a summary note; compiles concept, entity, project and memory pages with verbatim-quote citations that the bundled commonplace tool verifies; organises synthesis with PARA; runs lint and persona reviews. Use whenever the user wants to research a topic over time, ingest documents or PDFs, build or query a knowledge base / second brain / Obsidian vault, remember things across sessions, compare options (medical aid, insurance, vendors), ground work in a legal matter, do enterprise architecture (TOGAF-style capabilities, use cases, vision, target architecture), or study a course or certification, even if they do not say "wiki" or "commonplace".
