## Overview

HVE Core supports a 9-stage project lifecycle, from initial setup through ongoing operations, with AI-assisted tooling at each stage. Every stage maps to specific agents, prompts, instructions, and skills that accelerate your work and reduce friction. Use this guide to navigate the full lifecycle and find the right tools for your current project phase.

## Stage Overview

> [!TIP]
> [Design Thinking](../../design-thinking/using-together.md) can feed into this lifecycle at three exit points. See the [DT-RPI integration guide](../../design-thinking/dt-rpi-integration.md) for details.

## Stage Transition Rules

1. Design Thinking Exit 1 to Stage 2: Problem statement complete (Methods 1-3) feeds Task Researcher in Discovery
2. Design Thinking Exit 2 to Stage 2: Validated concept (Methods 4-6) feeds Task Researcher in Discovery
3. Design Thinking Exit 3 to Stage 2: Implementation spec (Methods 7-9) feeds Task Researcher in Discovery
4. Stage 1 to Stage 2: Installation complete
5. Stage 2 to Stage 3: BRD complete, handoff at `docs/brds/`
6. Stage 2 to Stage 4: TPMs skip PRD when BRD is sufficient
7. Stage 3 to Stage 4: PRD and ADRs finalized
8. Stage 4 to Stage 5: Work items created
9. Stage 5 to Stage 6: Sprint planned
10. Stage 6 to Stage 7: Implementation complete, `/clear` context
11. Stage 7 to Stage 8: PR approved
12. Stage 7 to Stage 6: Rework needed
13. Stage 8 to Stage 6: Next sprint
14. Stage 8 to Stage 9: Final sprint complete
15. Stage 9 to Stage 6: Hotfix needed

## Coverage Notes

Stage 6 Implementation carries the highest asset density with 30 assets, representing roughly 35% of all stage assignments. Stage 8 Delivery has zero agents and operates entirely through prompts and auto-activated instructions. Stage 1 Setup has minimal coverage with only 4 assets, reflecting its narrow scope as a one-time onboarding step.

Each stage page follows a consistent structure covering purpose, key activities, AI-assisted workflow, and cross-references. This format lets you navigate directly to the stage relevant to your current work and find both manual checklists and AI agent commands. Stages with fewer tools (Stage 1 through Stage 5) use flat tables, while stages with more tools (Stage 6 through Stage 9) use categorized subsections for navigability.
