Catryna Wikinelli
catrynaMIT · plugin-distributedCatryna Wikinelli is the Sothis suite’s living documentation: a git-versioned knowledge base of plain .mdx files in a .docs/ folder in your own repo. Agents search it through MCP before they build and write it back in the same session; your team reads the same files in a local viewer with search, diagrams and version history.
Why it exists
Documentation has a half-life. The doc was true the day it was written, then the code moved on and nobody told the doc. Wikis in Notion or Confluence drift because updating them is a separate chore from writing code — Catryna makes it the same chore.
What it does
The agent searches the docs before writing a feature, instead of rediscovering the architecture from source.
The agent writes and revises docs in the same session as the code change.
Every doc anchors to the source files it describes, so drift is detectable rather than assumed.
catryna drift names every doc the code has already outgrown, then hands an agent the doc plus the diffs.
Install and run
Inside Claude Code
$claude plugin install catryna@sirius-foresterRegisters the MCP server, activates the agent skill, and adds the /catryna:viewer command.
Read them yourself
/catryna:viewerBoots the human docs viewer on localhost:1307 — fuzzy search, Mermaid and React Flow diagrams, version history with diff and one-click revert.
Installing the whole suite at once is a different path —the plugins first, then every CLI in one shot.
