• · args envelope (task/contract/spec path)
• · context files if provided

• · structured result per phase schema
• · markdown report/findings

• · Claude API (agentic model)
• · parallel() executor

• · args envelope valid
• · required paths accessible

• · Agent schema mismatch
• · Missing upstream phase data

• · Structured input/output schemas
• · Phase dependency graph
• · Test strategy documented
