LLM Wiki, Obsidian & OKF
Wadachi doesn't invent a storage religion — it adopts the emerging standards and adds what they lack.
The LLM Wiki pattern
Karpathy's pattern (April 2026): agent memory as a maintained markdown wiki —
raw sources → wiki pages with <a class="wl" href="wikilinks.html">wikilinks</a> → a schema file with the conventions;
plus an index.md catalog and an append-only log.md. Wadachi's brain is this
pattern (The brain on disk): the wiki layer is global/ + projects/, the schema file is
SCHEMA.md (created by init, then yours), index and log are maintained on every
write.
What wadachi adds on top is the cognitive cycle the pattern lacks: Beliefs, staleness & decay, provenance, Provenance & time-travel, Sleep — consolidation, proposed.
Obsidian: format, not dependency
The brain dir is a valid Obsidian vault — open it and you get reading, searching, and the graph view for free. Zero lock-in either way: wadachi never requires Obsidian; Obsidian needs nothing from wadachi.
One catch: prose references like "memory #42" and [[#42]] are edges in wadachi's
graph, but Obsidian only resolves <a class="wl" href="file-name.html">file-name</a> links. Hence:
wadachi obsidian --dry-run # see what would change
wadachi obsidian # generate the links
Explicitly on demand — never automatic. It appends a marked Links: section
with <a class="wl" href="slug.html">slug</a> wikilinks to files that reference other memories by id. Prose
untouched, every change versioned, embeddings invalidated for reindexing,
idempotent. Your Obsidian graph lights up.
OKF — Open Knowledge Format
Google's vendor-neutral spec (2026) for agent knowledge: a directory of markdown
files with YAML frontmatter, type as the only required field, tolerant consumers.
Every wadachi memory file carries type: memory — your brain is a conformant OKF
bundle as it sits on disk. Any OKF consumer can read it; wadachi doctor --fix
upgrades pre-OKF brains in place.
Portability in every direction is the point: markdown for humans, vault for Obsidian, bundle for OKF, export for everything at once.
