#138 — Sub-Agent Question Propagation Fix

Phase 3 — Harness and Regression Tests

Task

Add tests that validate the question-policy-before.ts plugin behavior.

Required Tests (from §7 Phase 3)

Test	Expected
@Coder-BE subagent calls question	Plugin blocks, writes Log Central event, records question payload, error instructs HANDOVER protocol
@Knowledge-Curator subagent calls question as child of Orchestrator	Plugin blocks, writes Log Central event
@Knowledge-Curator subagent calls question as child-of-child from another subagent	Same block; KC instruction no longer encourages the call
@Orchestrator primary calls question	Allowed
@Super-Admin primary calls question	Allowed for destructive confirmation
Dispatched @Super-Admin calls question	Blocked/escalated to parent
Subagent HANDOVER includes ## Questions for User	Orchestrator approval flow reads and relays

Implementation

• Can be added to framework-self-test.ts as new checks
• Or added as a separate harness script in .opencode/scripts/
• Must validate both the plugin block behavior AND the HANDOVER protocol workflow

✅ Completed — Added 4 new self-test checks to framework-self-test.ts:

• Check 60: Verifies all 8 subagents have question: "deny" in opencode.json
• Check 61: Verifies question is NOT in subagent YAML frontmatter mcp_tools
• Check 62: Verifies question-policy-before.ts plugin exists with correct exports
• Check 63: Verifies subagent-preamble.md contains Step 0d with all required HANDOVER sections
