Scoped to 7 WORK_TOOLS only — Agent, Skill, TaskCreate etc. always pass. Subagents and active delegations bypass. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Subagents saw the stub and tried to delegate instead of doing work. The blocking hook already bypasses subagents, but the injected instructions were still telling them to delegate. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The flag was referenced by require_delegation.py to bypass blocking for active delegations, but no code ever created it — the creation logic was removed in v2.0.0. Now created in the PostToolUse hook that already detects delegate invocations. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
