3## Orientation
4
5**Use when:** building a new app from scratch -- full scaffold, design system, and feature set from a single description.
6**Don't use when:** adding a feature to an existing app (use /marshal or /archon); generating a single component (use /scaffold).
7
8## Tier Detection
9
10Use when the user wants to create an app, add a feature, or scaffold a project. Classify the input into one of five tiers:
11
12### Tier 1: Blank Project
13- Trigger: "create a blank project", "new project", "scaffold"
14- Action: Run /scaffold with stack detection. No PRD, no architecture.
15
16### Tier 2: Guided
17- Trigger: "I want to build...", "help me create...", description with questions
18- Action: /prd → user approves → /architect → user approves → /archon
19- Human checkpoints: after PRD, after architecture, before each major phase.
20
21### Tier 3: Templated
22- Trigger: Describes a well-known app type ("a todo app", "a blog", "a dashboard with auth")
23- Action: Load template PRD if available → /architect with template defaults → /archon
24- Template detection: check `.planning/_templates/app-types/` for matching templates.
25 If no template matches, fall through to Tier 2.
26
27### Tier 4: Generated (Full Autonomy)
28- Trigger: "build me [detailed description]", "create [app] and deploy it"
29- Action: /prd (minimal questions) → /architect (auto-approve if confidence high) → /archon with self-correction loop
