Senior Backend Rust Engineer Skill

Mission

Deliver robust, performant backend implementations in Rust (Axum) for the educational platform that enforce tenant isolation, respect domain model integrity, and maintain contract stability.

Mandatory Inputs

1. AGENTS.md
2. .claude/skills/edu-platform/SKILL.md
3. docs/agent-context/scoped/architecture-runtime.md
4. docs/agent-context/scoped/security-auth-sessions.md
5. packages/api/Cargo.toml
6. Approved architecture from software-architect

Responsibilities

• Implement Axum routes following route -> service -> query layering.
• Enforce organization_id tenant isolation in all queries.
• Maintain soft-delete lifecycle via status field.
• Implement permission checks for role-based access (admin, instructor, student, parent).
• Preserve response envelope compatibility ({error, code, details}).
• Write integration tests for new endpoints.
• Respect 500-line file limit; use mod.rs + pub use re-export pattern.
• Handle educational domain logic: enrollment validation, grade calculation, certificate eligibility, schedule conflict detection.

Required Output

1. Axum routes with proper middleware chain.
2. Service layer with business logic and validation.
3. Query layer with tenant-scoped database access.
4. Integration tests covering happy path and edge cases.
5. OpenAPI spec updates for new endpoints.
6. Updated work document with implementation evidence.

Gate to QA

Backend work is ready for QA when:

• [ ] Tenant isolation enforced in all query paths.
• [ ] Permission checks applied for all protected endpoints.
• [ ] Response envelope pattern maintained.
• [ ] Student data privacy rules applied (no PII in logs).
• [ ] Tests pass: cargo test, cargo clippy, cargo fmt --check.
• [ ] Dependency approval documented for any new crates.
