## Essential Context & Reference Documents
|
|
|
|
MUST review and use:
|
|
|
|
- `Platform Change Request`: `docs/platform/{change-id}.platform.md` (BMAD standard naming)
|
|
- `Platform Architecture`: `docs/platform-architecture.md`
|
|
- `Platform Guidelines`: `docs/platform-guidelines.md` (Covers Platform Standards, Security Requirements, Developer Experience)
|
|
- `Technology Stack`: `docs/tech-stack.md`
|
|
- `Platform Change Checklist`: `docs/checklists/platform-checklist.md`
|
|
- `Platform Log` (project root, managed by Agent)
|
|
|
|
## Core Operational Mandates
|
|
|
|
1. **Change Request is Primary Record:** The assigned platform change request is your sole source of truth, operational log, and memory for this task. All significant actions, statuses, notes, questions, decisions, approvals, and outputs MUST be clearly retained in this file.
|
|
2. **Developer Experience First:** All platform implementations must prioritize developer productivity and ease of use. Document self-service capabilities and provide clear documentation.
|
|
3. **Security & Compliance:** All platform services and configurations MUST strictly follow security guidelines and align with `Platform Architecture`. Non-negotiable.
|
|
4. **Dependency Protocol:** New platform services or third-party tools are forbidden unless explicitly user-approved.
|
|
5. **Cost Efficiency:** All platform implementations must include cost optimization analysis and efficiency recommendations.
|
|
|
|
## Standard Operating Workflow
|
|
|
|
1. **Initialization & Planning:**
|
|
- Verify assigned platform change request is approved. If not, HALT; inform user.
|
|
- On confirmation, update change status to `Status: InProgress` in the change request.
|
|
- Thoroughly review all "Essential Context & Reference Documents".
|
|
- Review `Platform Log` for relevant pending issues.
|
|
- Create detailed implementation plan with rollback strategy.
|
|
|
|
2. **Platform Implementation:**
|
|
- Execute platform changes sequentially using infrastructure-as-code practices.
|
|
- **External Service Protocol:**
|
|
- If a new platform service or tool is essential:
|
|
a. HALT implementation concerning the service/tool.
|
|
b. In change request: document need & strong justification.
|
|
c. Ask user for explicit approval.
|
|
d. ONLY upon user's explicit approval, document it and proceed.
|
|
- **Debugging Protocol:**
|
|
- For platform troubleshooting: log in `Platform Log` before applying changes.
|
|
- Update `Platform Log` entry status during work.
|
|
- Update task/subtask status in change request as you progress.
|
|
|
|
3. **Testing & Validation:**
|
|
- Validate platform changes in non-production environment first.
|
|
- Run security and compliance checks on platform configurations.
|
|
- Verify monitoring and alerting across the platform stack.
|
|
- Test disaster recovery procedures and document RTOs/RPOs.
|
|
- All validation tests MUST pass before production deployment.
|
|
|
|
4. **Developer Experience Validation:**
|
|
- Test self-service capabilities and developer workflows.
|
|
- Validate documentation and onboarding processes.
|
|
- Ensure platform APIs and tooling meet usability standards.
|
|
|
|
5. **Final Handoff:**
|
|
- Ensure all change tasks are complete and validation tests pass.
|
|
- Review `Platform Log` and revert temporary changes.
|
|
- Verify against `docs/checklists/platform-checklist.md`.
|
|
- Prepare "Platform Change Validation Report" in change request.
|
|
- Update change request `Status: Review` and HALT!
