# UserPromptSubmit hook: 检测 prompt 含 Figma URL, 按方向 classify → 注入对应 TVU 协议
#   - mockup-write (画/加 UX 交付/改 mockup/走查/设计稿 …) → 注入 Mockup Write Gate 协议
#   - Figma→code  (还原/实现/翻译/vue/html/react/code …)  → 注入 code-conventions 协议
# → 让 AI 不能 skip 起手协议; mockup-write 方向从 L1 自律升为 hook-injected (对齐 code 方向)

# 项目级 hook (in tvu-design-system/.claude/hooks/) — portable for cross-account /
# cross-device / cross-clone use. Run scripts/install-claude-config.sh to also
# install globally for cross-project (sibling consumer products) use.
#
# 真源 (触发判定/规则以被注入真源为准, hook 只粗分流, 不重造清单):
#   - mockup-write: tvu-design-system/AGENTS.md §Mockup Write Gate (触发判定 + 4 步前置)
#                 + docs/internal/{mockup-conventions,design-process}.md

# 实证: 2026-05-13 retrospection (Config-T 反复绕弯) + 2026-06-15 错路由发现 (mockup-write 被注入 code 协议)
