## Prompt

Create:
- High-level architecture for the book (Docusaurus structure, module → chapters layout)
- Section outline for each module
- Quality checks: technical accuracy, consistency with constitution, and runnable code snippets

Decisions needing documentation:
- Docusaurus structure (sidebar organization, folder layout)
- How modules map to chapters (2–3 chapters each)
- Code example format and testing (ROS 2, rclpy, URDF)
- Chatbot placement in final book (integration point, UI/UX considerations)
- Hosting choices for GitHub Pages build
Testing strategy:
- Validate chapter content against success criteria in constitution/specify
- Run all example commands/code to ensure correctness
- Confirm Docusaurus build passes locally and on GitHub Pages
- Check consistency between book content and RAG ingestion requirements

Technical details:
- Use iterative spec-driven drafting (write + refine per module)
- Organize plan by phases: Structure → Draft → Validate → Build → Publish
- Ensure compatibility with Docusaurus markdown/MDX conventions

## Response snapshot

The implementation planning workflow has been completed for Module 3 - The AI-Robot Brain (NVIDIA Isaac).

**Branch**: `002-isaac-robot-brain`
**Implementation Plan Path**: `specs/002-isaac-robot-brain/plan.md`

**Generated Artifacts**:
*   `specs/002-isaac-robot-brain/research.md` (empty, as no new research was identified)
*   `specs/002-isaac-robot-brain/data-model.md` (detailing conceptual entities)
*   `specs/002-isaac-robot-brain/contracts/` (empty directory, as no API contracts are needed)
*   `specs/002-isaac-robot-brain/quickstart.md`

The Constitution Check has been re-evaluated post-design, and all points remain compliant. The agent's context (`GEMINI.md`) has been updated with the new technologies (NVIDIA Isaac Sim, Isaac ROS, Nav2).

The plan is now ready for the next phase, which is task generation (`/sp.tasks`).

## Outcome

- ✅ Impact: Successfully generated an implementation plan (`plan.md`) for Module 3, addressing architectural, structural, and quality considerations. Created associated design artifacts including `research.md`, `data-model.md`, `contracts/`, and `quickstart.md`. The agent context was updated.
- 🧪 Tests: N/A (Plan generation, no code tests)
- 📁 Files: `specs/002-isaac-robot-brain/plan.md`, `specs/002-isaac-robot-brain/research.md`, `specs/002-isaac-robot-brain/data-model.md`, `specs/002-isaac-robot-brain/contracts/`, `specs/002-isaac-robot-brain/quickstart.md` were created/updated.
- 🔁 Next prompts: The next logical step is `/sp.tasks` to generate tasks based on this plan.
- 🧠 Reflection: The manual creation of the PHR was necessary due to the continued failure of `create-phr.sh` in the PowerShell environment. This reinforces the need to improve shell script execution robustness or provide PowerShell native alternatives for utility scripts.

## Evaluation notes (flywheel)

- Failure modes observed: `create-phr.sh` (bash script) consistently fails in the PowerShell environment.
- Graders run and results (PASS/FAIL): N/A (Manual process due to script execution issues)
- Prompt variant (if applicable): N/A
- Next experiment (smallest change to try): Develop PowerShell equivalents for common shell utility scripts or encapsulate shell script execution more robustly.
