When the stack builder picks it
The builder reads each job's rules from the top and takes the first step whose conditions hold and whose plan fits the money left. Kiro is named in these steps:
- AI coding, step 4 of 4, otherwise: Pro ($20/mo); the step also names Claude Code, OpenAI Codex, Cursor, Devin and Augment Code, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
