Ai Vision

AI Vision

Overview

This skill provides a standalone CLI to call multimodal models for UI querying, assertion, and single-step planning. It does not depend on device type; you supply a screenshot and receive structured output (coordinates, decisions, or next actions). Execution and multi-step loops are handled externally by agents using adb/hdc or other drivers. Prefer storing screenshots in ~/.eval/screenshots/ and add timestamps to avoid overwriting.

Path Convention

Canonical install and execution directory: ~/.agents/skills/ai-vision/. Run commands from this directory:

cd ~/.agents/skills/ai-vision

One-off (safe in scripts/loops from any working directory):

(cd ~/.agents/skills/ai-vision && npx tsx scripts/ai_vision.ts --help)

Model Configuration

Default Doubao configuration via environment variables:

• ARK_BASE_URL (e.g. https://ark.cn-beijing.volces.com/api/v3)
• ARK_API_KEY
• ARK_MODEL_NAME

For non-Doubao providers, pass explicit flags:

• --base-url, --api-key, --model

Default model if none provided: doubao-seed-1-6-vision-250815.

Script

Path: scripts/ai_vision.ts

Run with:

npx tsx scripts/ai_vision.ts --help

Log level (for troubleshooting raw model response):

npx tsx scripts/ai_vision.ts --log-level debug  [flags]

Output formatting:

• When --log-json is set, logs are emitted as JSON.
• Otherwise, the final result is pretty-printed JSON, and logs are colorized when TTY is available.

AIQuery

npx tsx scripts/ai_vision.ts query \
  --screenshot ~/.eval/screenshots/ui_YYYYMMDD_HHMMSS.png \
  --prompt "请识别屏幕上的‘搜索’按钮，并返回其坐标"

AIAssert

npx tsx scripts/ai_vision.ts assert \
  --screenshot ~/.eval/screenshots/ui_YYYYMMDD_HHMMSS.png \
  --prompt "当前页面包含搜索框"

plan-next (single-step planning)

npx tsx scripts/ai_vision.ts plan-next \
  --screenshot ~/.eval/screenshots/ui_YYYYMMDD_HHMMSS.png \
  --prompt "点击放大镜图标进入搜索页"

Output Notes

• plan-next returns a normalized next action with absolute pixel coordinates.
• If the model outputs relative coordinates (1000x1000), the script scales to screen pixels.
• Combine with adb/hdc actions (e.g., adb shell input tap X Y) for device control.
• Use --log-level debug to print the raw model response for troubleshooting.

Default Models (Doubao)

• doubao-seed-1-8-251228
• doubao-seed-1-6-vision-250815
