Kythene ships a plugin + skill bundle for Claude Code. One install does two things: it connects Claude to your workspace over MCP, and it teaches your agent the Kythene workflow - so it recalls context at the start of a session, remembers what it learns, publishes work for the team, and picks up feedback, without you having to prompt each step.
You do not need the skill to use Kythene - the MCP tools work on their own (see MCP and agents). The skill just makes an agent use them well, unprompted.
What the skill teaches
- Catch up first. At the very start of a session it calls catch-up, so the agent opens knowing what changed while it was away - your other agents' and teammates' publishes, versions, feedback and memory changes since it last looked. That's how "what did the other session do?" gets answered automatically rather than by chance.
- Recall first. At the start of a session on a connected project, recall the project's memory - decisions, gotchas, conventions, prior findings - and read it before doing anything, so nothing is re-derived. Recall also returns the workspace guide, so the agent follows the team's house style (taxonomy, memory vs collection, what not to store) without being told each time.
- Remember as you go. Store durable facts and decisions with a title and a project, so what one session learns the next can use. Re-using a title in the same project supersedes the old memory, keeping it current.
- Keep memory true. When a recalled memory contradicts the live system, correcting it is part of the task. Verify against the real system first, then supersede it (same title and project) or deprecate it with a replacement, and say what changed. Never leave a memory you know to be false in place.
- Publish your work. Push outputs - a result, a doc, a dataset, a binary - as collections the team and their agents can read, comment on and build on.
- Pick up feedback. Check the inbox for comments and approvals on your previous publishes and fold them into what you do next.
- Stay collision-aware. Report what you are working on and check who else (or which agent) is active in the same area.
Install
For the hosted service, in Claude Code:
/plugin marketplace add kythene/plugin
/plugin install kythene@kytheneIf you self-host, add the marketplace served by your own instance instead, so the plugin points at your box:
/plugin marketplace add https://<your-instance>/.claude-plugin/marketplace.json
/plugin install kythene@kytheneOn older clients that can't add a marketplace by reference, download kythene-plugin.zip from Connect your AI in the app and add it locally as a fallback:
unzip kythene-plugin.zip
/plugin marketplace add ./kythene
/plugin install kythene@kytheneThe bundle sets up the MCP connection and installs the kythene-workflow skill. The first time your agent calls a Kythene tool, Claude opens a browser to log you in and authorise it (OAuth) - no API key needed for MCP.
Other clients
The skill is Claude-Code-specific, but the workflow it encodes is not: on any MCP-capable client you can ask your agent to recall, remember, publish and review in plain language, and it will use the same tools. See Getting started to connect a client, and the CLI reference for terminal and scripted use.
