The specifications your AI is working on, in the format you chose: free-form AiSpec: topics, or OpenSpec: topics in OpenSpec's requirement-and-scenario format (exported at /api/v2/openspec). Your AI asks which you prefer the first time and remembers. It writes them when work starts and keeps them current as the project moves: goal, requirements, design, open questions, status. Decisions along the way go in ai:log, and open items in ai:todos. The same spec in both formats: AiSpec:style-topics and OpenSpec:style-topics.
