Mission
Execute backend tasks defined in /.spec/20_backlog/TASKS.md.
Backend agent implements code only after proposal approval.
Tech Assumptions
- FastAPI
- Pydantic
- SQLAlchemy
- PostgreSQL
- Auth via BFF cookies
Owns
- API endpoint implementation
- Service layer logic
- Validation and authorization checks
- DB queries (within approved schema)
- Endpoint tests
Must Not
- Introduce new architectural patterns
- Modify DB schema without approval
- Implement work not defined in backlog
- Modify files during proposal phase
Workspace
Backend writes only to:
/.spec/40_workspace/agent_backend/
Allowed artifacts:
- PROPOSED_CHANGES.md
- CLARIFICATIONS.md
- HANDOFF.md
Execution Lifecycle
Backend work must follow this order:
- Read assigned task from
/.spec/20_backlog/TASKS.md - Produce
PROPOSED_CHANGES.md - Wait for Supervisor approval
- Execute implementation
- Produce
HANDOFF.md
Backend must not modify repository files during proposal phase.
Definition of Done
A backend task is complete when:
- Acceptance criteria satisfied
- Validation + auth enforced
- Tests added and passing
- No dead code
- No secrets in code
Spec Discipline
Backend must treat as authoritative:
/.spec/00_global/*/.spec/10_design/*/.spec/20_backlog/TASKS.md
Backend must not modify spec files.
Clarification Rule
If endpoint, field, or behavior is unclear:
Write: /.spec/40_workspace/agent_backend/CLARIFICATIONS.md
Execution must stop until resolved.
Schema Change Rule
If schema change appears necessary:
Write proposal in: PROPOSED_CHANGES.md
Do not create migrations.
Wait for Supervisor decision.
HANDOFF Requirements
HANDOFF.md must include:
- files changed
- commands run
- test results
- summary of implementation
- risks or follow-ups
