## 唐磊模型切换 DeepSeek-V4-Flash-Vision-Exp
|
||||||
|
|
||||||
|
- 背景：唐磊（ou_b048b1554913b061ae24ae15a89d6d3b）后续主要做硬件设计、画 PCB，需要看图能力（原理图/PCB/datasheet/封装/波形）
|
||||||
|
- 方案：新增 `hw` agent，默认模型 `deepseek/deepseek-v4-flash-vision-exp`（text+image），通过 bindings 把唐磊飞书 DM 精确路由到 hw
|
||||||
|
- 路由：`{agentId: hw, match: {channel: feishu, peer: {kind: direct, id: ou_b048b1554913b061ae24ae15a89d6d3b}}}`；main agent 兜底 feishu
|
||||||
|
- 模型验证：官方定价与 v4-flash 相同（input $0.22/1M, output $0.66/1M, 1M ctx），实测推理正常
|
||||||
|
- 配置备份：~/.openclaw/openclaw.json.bak.vision-*
|
||||||
|
- 注意：bindings 是追加到 config 的顶层 key；agents.list 热重载生效，bindings 需配合 openclaw agents list 验证

## KiCad 项目命名规范
|
||||||
|
|
||||||
|
- 每个 KiCad 工程放在其项目子目录内，命名为 `<项目名>-kicad/`
|
||||||
|
- 例：环路车检器 → `loop-detector/loop-detector-kicad/`
|
||||||
|
- 工程文件统一命名（避免与目录名重复冲突）：
|
||||||
|
- 原理图：`<项目名>.kicad_sch`
|
||||||
|
- PCB 布局：`<项目名>.kicad_pcb`
|
||||||
|
- 工程文件：`<项目名>.kicad_pro`
|
||||||
|
- 自定义符号库：`<项目名>.kicad_sym`
|
||||||
|
- 导出交付件（PDF / PNG / Gerber）与源文件同目录存放，便于一站式出档
|
||||||
|
- 一个项目只对应一个 `-kicad/` 目录，不要散落
