Built on opencode
AI coding built for
structured development
Define what you're building, architect how it fits together, and track what has changed — before a single line of code is written.

Features
Premise adds three structured tabs to the AI coding workflow — each one writes a file you can commit alongside your code.
Generate a structured app summary and requirements document from your session conversation. Each requirement has a lifecycle you can track.
Generate and explore AI-produced architecture diagrams interactively. Three diagram views — component, deployment, and composite structure — built on React Flow.
Browse the full history of prompt executions in your session. See exactly which files changed for each prompt with addition and deletion stats.
Built-in Agents
Three specialized agents, each scoped to a specific job and the files it is allowed to write.
| Agent | Purpose | Writes |
|---|---|---|
| requirements | Reads the session and produces a summary and structured requirements document | .premise/summary.md .premise/requirements.md |
| requirement-plan | Maps committed requirements to detailed implementation plans | .premise/plans/*.md |
| architecture | Analyses the codebase and produces the architecture graph | .premise/architecture*.json |
