The problem it solves

Most project tools were designed for people clicking through screens. An agent can be connected to them, but the tool was not built for the agent:

• writes are not safe to retry, so a repeated call duplicates work;
• errors do not say which rule was broken;
• nothing distinguishes what an agent did from what a person did;
• the agent's working rules live in a prompt nobody maintains.

Quasar starts from the opposite end. A coding agent should read and update the project state as naturally as it reads and writes code. Every person and every agent that touches a project should also be able to see:

• what was decided;
• what the plan was;
• what was delivered.
