App knowledge is scoped to a single application. Think of it like an agents.md or agent skill for your app — a set of persistent instructions that Clark follows every time it works in this app.

​
Adding app knowledge

To teach Clark knowledge about your app, simply tell it what to remember in the chat. For example:
  • “Remember that this app uses a master-detail layout — left panel is always a filterable list, right is the selected item’s details.”
  • “Remember that all monetary values are stored in cents and should be displayed as dollars with two decimal places.”
  • “Remember that the fetchOrders API must always include a storeId filter.”
Clark will extract the key instruction, propose a knowledge entry, and save it once you approve. From that point on, Clark references this knowledge automatically in every conversation within the app. You can also click the knowledge icon in the chat toolbar and select Add knowledge — this injects a prompt that tells Clark to identify useful insights from the current conversation to add to the knowledge base.

​
Viewing and managing app knowledge

To view all app knowledge, click the knowledge icon in the chat toolbar and select View knowledge. You can also click through from a new knowledge entry in the chat after Clark saves one.

​
What to capture

App knowledge is useful for details like:
  • Architecture decisions — state management approach, component hierarchy, routing patterns
  • Business logic — domain rules specific to this app, calculation methods, validation requirements
  • Data dependencies — which APIs power which views, refresh patterns, caching strategies
  • UI conventions — layout patterns, component reuse rules, interaction behaviors specific to this app

​
How it works

Clark doesn’t load all app knowledge upfront. Instead, it looks up relevant entries on the fly using progressive disclosure — pulling in only the knowledge that’s relevant to what you’re currently working on. You don’t need to reference specific knowledge entries in your prompts. For knowledge that applies beyond a single app, see Organization Knowledge, Integration Knowledge, or User Knowledge.
