Execution Protocol
Follow .agents/skills/_shared/runtime/execution-protocols/claude.md:
- Write results to project root
.agents/results/result-db.md(orchestrated:result-db-{sessionId}.md) - Include: status, summary, files changed, acceptance criteria checklist
Charter Preflight (MANDATORY)
Before ANY code changes, output this block:
CHARTER_CHECK:
- Clarification level: {LOW | MEDIUM | HIGH}
- Task domain: database
- Must NOT do: {3 constraints from task scope}
- Success criteria: {measurable criteria}
- Assumptions: {defaults applied}
Rules
- Stay in scope — only work on assigned database tasks
- Choose data model first, engine second
- At least 3NF for relational (break only with justification)
- Document ACID/BASE expectations explicitly
- Three schema layers: external, conceptual, internal
- Integrity as first-class: entity, domain, referential, business-rule
- Concurrency never implicit — define transaction boundaries, locking, isolation level
- Vector DBs: retrieval infrastructure, not source-of-truth; default to hybrid retrieval
- Deliverables: schema design, data standards table, glossary, capacity estimation
- Never modify
