What it does
Image Compress is an agent skill from dongsheng123132/u-claw. 图片压缩/转换 - 批量压缩、改尺寸、转格式（jpg/png/webp），本地处理不失隐私
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office. The repository describes itself as: U-Claw 虾盘 — OpenClaw AI 助手离线安装 U 盘：一键装好 Claude Code/Codex/OpenClaw，无需联网即插即用；新品 U-King AI 装机管家详见 u-king.org，另有远程支持与定制 AI 开发。 The licence is MIT.
When your agent uses it
- Documents & Office work in your project
Example prompts
- “/image-compress”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 9e769e6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pythonpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Image Compress loads about 274 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 35 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 图片压缩/转换 - 批量压缩、改尺寸、转格式（jpg/png/webp），本地处理不失隐私
图片压缩 / 转换
帮用户压缩图片体积、调整尺寸、转换格式，全部本地处理，照片不外传。
能力概述
- 压缩：降低体积（控制质量/分辨率），适合发邮件、传微信
- 改尺寸：按宽高或百分比缩放
- 转格式：jpg / png / webp 互转（webp 体积最小）
- 批量：处理整个文件夹
操作方式
用 Bash 工具，Python 的 Pillow 库（跨平台、纯本地）：
python -c "import PIL" 2>/dev/null || pip install -q Pillow
# 单张压缩（质量 75，宽度限制 1600px 等比缩放）
python - <<'PY'
from PIL import Image
im = Image.open("input.jpg")
if im.width > 1600:
im = im.resize((1600, int(im.height*1600/im.width)))
im.convert("RGB").save("output.jpg", "JPEG", quality=75, optimize=True)
print("已压缩 -> output.jpg")
PY
# 批量：当前目录所有 jpg/png -> webp（体积更小）
python - <<'PY'
from PIL import Image
import glob, os
for f in glob.glob("*.jpg") + glob.glob("*.png"):
out = os.path.splitext(f)[0] + ".webp"
Image.open(f).save(out, "WEBP", quality=80)
print(f"{f} -> {out}")
PY使用建议
- 处理前
ls -lh看原图体积，处理后再ls -lh对比，告诉用户压缩了多少 - 默认不覆盖原图（输出新文件名），除非用户明确要求覆盖
- 含透明通道的 PNG 转 JPG 会丢透明，转 webp 可保留——按需选格式
