About wiki
wiki is a persistent, project-local Markdown knowledge base for storing and retrieving project and session information. It combines keyword and tag search with page health checks and automatic capture of notable session findings.
Key features
- 01Ingest knowledge across pages
- 02Search by keywords and tags
- 03Check wiki page health
- 04Quickly add, read, and delete pages
- 05Capture notable session findings
Use cases
- 01Record project architecture and decisions
- 02Find project knowledge by keywords
- 03Check for orphaned or stale pages
- 04Preserve significant session discoveries
Install

Details
From the project READMEWiki
Persistent, self-maintained markdown knowledge base for project and session knowledge. Inspired by Karpathy's LLM Wiki concept.
Operations
Ingest
Process knowledge into wiki pages. A single ingest can touch multiple pages.
wiki_ingest({ title: "Auth Architecture", content: "...", tags: ["auth", "architecture"], category: "architecture" })
Query
Search across all wiki pages by keywords and tags. Returns matching pages with snippets — YOU (the LLM) synthesize answers with citations from the results.
wiki_query({ query: "authentication", tags: ["auth"], category: "architecture" })
Lint
Run health checks on the wiki. Detects orphan pages, stale content, broken cross-references, oversized pages, and structural contradictions.
wiki_lint()
Quick Add
Add a single page quickly (simpler than ingest).
wiki_add({ title: "Page Title", content: "...", tags: ["tag1"], category: "decision" })
List / Read / Delete
wiki_list() # Show all pages (reads index.md)
wiki_read({ page: "auth-architecture" }) # Read specific page
wiki_delete({ page: "outdated-page" }) # Delete a page
Log
View wiki operation history by reading .omc/wiki/log.md.
Categories
Pages are organized by category: architecture, decision, pattern, debugging, environment, session-log
Storage
- Pages:
.omc/wiki/*.md(markdown with YAML frontmatter) - Index:
.omc/wiki/index.md(auto-maintained catalog) - Log:
.omc/wiki/log.md(append-only operation chronicle)
Cross-References
Use [[page-name]] wiki-link syntax to create cross-references between pages.
Auto-Capture
At session end, significant discoveries are automatically captured as session-log pages. Configure via wiki.autoCapture in .omc-config.json (default: enabled).
Hard Constraints
- NO vector embeddings — query uses keyword + tag matching only
- Wiki pages are git-ignored by default (
.omc/wiki/is project-local)
Model Routing
haiku— quick lookups, lightweight inspection, narrow docs worksonnet— standard implementation, debugging, and reviewopus— architecture, deep analysis, consensus planning, and high-risk reviewfable— Claude Fable 5 (above Opus); pass it explicitly on the Task call or pin it per agent withagents.<name>.model- The session model chosen with
/modelapplies to the main loop only. Delegated agents run on their pinned tier unless the Task call passesmodelexplicitly or the agent is overridden viaagents.<name>.model. To run delegated work on Fable, use one of those two surfaces; selecting Fable in/modelalone does not change delegation.
