Robot-dog integration, bring-up, HIL planning, prototype readiness, hardware gate, assembly test, first power-on checklist, data capture, and physical test safety validation. Use this skill when the user asks whether a prototype is ready for assembly, power-on, HIL, bring-up, hardware testing, or real-world data collection after digital-twin gates.
Sim-to-real calibration skill for robot-dog virtual prototypes. Use this skill when comparing simulation logs against physical prototype logs, estimating friction/mass/latency/torque scale/contact parameter corrections, reducing sim-real gap, or generating parameter updates for MuJoCo/PyBullet/digital twin.
Robot-dog firmware dry-run planning and validation skill for MCU target, motor-control loop, CAN protocol, safety state machine, calibration contract, build manifest, and hardware bring-up gates. Use this skill when the user asks for embedded firmware, motor firmware, FOC loop, CAN frames, calibration, firmware project scaffolding, or safe pre-flash validation.
Electronics BOM and robot-dog component selection MVP. Use this skill when the user asks for electronic BOM, MCU/driver/encoder/power/connector selection, JLCPCB/LCSC-ready part candidates, curated robot electronics library, BOM rationale, availability checks, or component choices to feed pcb, circuit simulation, firmware, and digital-twin gates.
Executable robot-dog motion-control MVP for leg IK, gait phase generation, trajectory contracts, controller parameters, and simulation/firmware handoff. Use this skill when the user asks for FK/IK, inverse kinematics, gait generator, trot/walk/bound trajectories, controller parameters, motion-control code, or a trajectory to feed simulation, MuJoCo, or firmware.

一句话起 server,后缀决定引擎。CAD 实跑(Three.js),PCB / SCH / SIM 占位待 P3 落地。
bash skills/viewer/scripts/start.sh /abs/path/to/<file> [workspace_root]
# stdout 唯一一行: http://127.0.0.1:<port>/?engine=<cad|pcb|sch|sim>&dir=...&file=...
from web_preview import start, snapshot
url = start("/abs/path/to/hip_bracket.step") # 拿 URL 直接打开
res = snapshot("/abs/path/to/hip_bracket.step") # 无浏览器时降级出图,见 headless-fallback.md
# res = {"tier":1|2|3, "kind":"url"|"png"|"json", "path":..., "fallback_reason":..., "duration_ms":...}
snapshot(mode=auto) 三档降级(P1-5 已落地):Tier 1 chromium 截图 → Tier 2 OCP/VTK PNG → Tier 3 dimensions JSON,逐级回落不静默。CLI:python web_preview.py --mode=auto|web|snapshot|probe <file>。

扩支持新格式 = scripts/backend/router.mjs 加一行 + scripts/engines/<name>/ 放静态文件。
http://127.0.0.1:<port>/?engine=<cad|pcb|sch|sim>&dir=<abs-dir>&file=<rel-file>
完整字段约束 + 安全规则见 references/url-protocol.md。跨子技能改动须在 shared/dependencies.md 同步。
/__cad/server → app="build123d-cad/viewer" + serverApiVersion>=2 + workspaceRoot 一致 + git 一致。--shutdown-after 12h,每请求重置;POST /__cad/shutdown 优雅关停(仅 127.0.0.1)。0 成功 / 2 后缀不支持或参数错 / 3 文件不存在 / 4 端口分配失败
?dir 必须在 --workspace-root 内,否则 403?file 防 .. 穿越,否则 403.json/.yaml/.yml,其它 415cd skills/viewer && pytest tests/ -v
CI 必跑(无浏览器,~9s):test_routing / test_url_assembly / test_placeholders
本地必跑(起 server):test_start / test_server_reuse / test_cad_engine
P1-5 降级链:test_headless_fallback(纯逻辑 CI 必跑 / 真渲染缺 OCP·vtk 时 skip)
P3 待落地:test_{pcb,sch,sim}_engine.py(skip)
