npx skills add https://github.com/aiskillstore/marketplace --skill slack-gif-creator一个提供实用工具和知识的工具包,用于创建针对 Slack 优化的动态 GIF。
尺寸:
参数:
from core.gif_builder import GIFBuilder
from PIL import Image, ImageDraw
# 1. 创建构建器
builder = GIFBuilder(width=128, height=128, fps=10)
# 2. 生成帧
for i in range(12):
frame = Image.new('RGB', (128, 128), (240, 248, 255))
draw = ImageDraw.Draw(frame)
# 使用 PIL 基本图形绘制你的动画
# (圆形、多边形、线条等)
builder.add_frame(frame)
# 3. 保存并优化
builder.save('output.gif', num_colors=48, optimize_for_emoji=True)
如果用户上传了图片,请考虑他们是否希望:
使用 PIL 加载和处理图片:
from PIL import Image
uploaded = Image.open('file.png')
# 直接使用,或仅作为颜色/风格的参考

从头开始绘制图形时,使用 PIL ImageDraw 的基本图形:
from PIL import ImageDraw
draw = ImageDraw.Draw(frame)
# 圆形/椭圆形
draw.ellipse([x1, y1, x2, y2], fill=(r, g, b), outline=(r, g, b), width=3)
# 星星、三角形、任何多边形
points = [(x1, y1), (x2, y2), (x3, y3), ...]
draw.polygon(points, fill=(r, g, b), outline=(r, g, b), width=3)
# 线条
draw.line([(x1, y1), (x2, y2)], fill=(r, g, b), width=5)
# 矩形
draw.rectangle([x1, y1, x2, y2], fill=(r, g, b), outline=(r, g, b), width=3)
不要使用: 表情符号字体(跨平台不可靠)或假设此技能中存在预打包的图形。
图形应该看起来精致且有创意,而不是基础简陋。方法如下:
使用更粗的线条 - 对于轮廓和线条,始终设置 width=2 或更高。细线(width=1)看起来粗糙且业余。
增加视觉深度:
create_gradient_background)让形状更有趣:
注意颜色:
对于复杂形状(心形、雪花等):
要有创意和注重细节!一个好的 Slack GIF 应该看起来精致,而不是像占位符图形。
core.gif_builder)组装帧并针对 Slack 优化:
builder = GIFBuilder(width=128, height=128, fps=10)
builder.add_frame(frame) # 添加 PIL Image
builder.add_frames(frames) # 添加帧列表
builder.save('out.gif', num_colors=48, optimize_for_emoji=True, remove_duplicates=True)
core.validators)检查 GIF 是否符合 Slack 要求:
from core.validators import validate_gif, is_slack_ready
# 详细验证
passes, info = validate_gif('my.gif', is_emoji=True, verbose=True)
# 快速检查
if is_slack_ready('my.gif'):
print("Ready!")
core.easing)平滑运动而非线性:
from core.easing import interpolate
# 进度从 0.0 到 1.0
t = i / (num_frames - 1)
# 应用缓动
y = interpolate(start=0, end=400, t=t, easing='ease_out')
# 可用选项:linear, ease_in, ease_out, ease_in_out,
# bounce_out, elastic_out, back_out
core.frame_composer)常见需求的便利函数:
from core.frame_composer import (
create_blank_frame, # 纯色背景
create_gradient_background, # 垂直渐变
draw_circle, # 绘制圆形的辅助函数
draw_text, # 简单文本渲染
draw_star # 五角星
)
用振荡偏移对象位置:
math.sin() 或 math.cos() 配合帧索引有节奏地缩放对象大小:
math.sin(t * frequency * 2 * math.pi) 实现平滑脉动物体下落并弹起:
interpolate() 配合 easing='bounce_out' 实现落地效果easing='ease_in' 实现下落(加速)效果围绕中心旋转对象:
image.rotate(angle, resample=Image.BICUBIC)逐渐出现或消失:
Image.blend(image1, image2, alpha)将对象从屏幕外移动到位置:
interpolate() 配合 easing='ease_out' 实现平滑停止easing='back_out'为缩放效果调整比例和位置:
创建向外辐射的粒子:
x += vx, y += vyvy += gravity_constant仅在要求减小文件大小时,实施以下几种方法:
num_colors=48 而不是 128remove_duplicates=Trueoptimize_for_emoji=True 自动优化# 表情符号的最大化优化
builder.save(
'emoji.gif',
num_colors=48,
optimize_for_emoji=True,
remove_duplicates=True
)

关于用户上传的说明:此技能不包含预构建的图形,但如果用户上传了图片,请使用 PIL 加载并处理它 - 根据他们的请求来解释他们是希望直接使用它还是仅作为灵感来源。
发挥创意!组合概念(弹跳 + 旋转、脉动 + 滑动等)并充分利用 PIL 的功能。

A toolkit providing utilities and knowledge for creating animated GIFs optimized for Slack.
Dimensions:
Parameters:
from core.gif_builder import GIFBuilder
from PIL import Image, ImageDraw
# 1. Create builder
builder = GIFBuilder(width=128, height=128, fps=10)
# 2. Generate frames
for i in range(12):
frame = Image.new('RGB', (128, 128), (240, 248, 255))
draw = ImageDraw.Draw(frame)
# Draw your animation using PIL primitives
# (circles, polygons, lines, etc.)
builder.add_frame(frame)
# 3. Save with optimization
builder.save('output.gif', num_colors=48, optimize_for_emoji=True)
If a user uploads an image, consider whether they want to:
Load and work with images using PIL:
from PIL import Image
uploaded = Image.open('file.png')
# Use directly, or just as reference for colors/style
When drawing graphics from scratch, use PIL ImageDraw primitives:
from PIL import ImageDraw
draw = ImageDraw.Draw(frame)
# Circles/ovals
draw.ellipse([x1, y1, x2, y2], fill=(r, g, b), outline=(r, g, b), width=3)
# Stars, triangles, any polygon
points = [(x1, y1), (x2, y2), (x3, y3), ...]
draw.polygon(points, fill=(r, g, b), outline=(r, g, b), width=3)
# Lines
draw.line([(x1, y1), (x2, y2)], fill=(r, g, b), width=5)
# Rectangles
draw.rectangle([x1, y1, x2, y2], fill=(r, g, b), outline=(r, g, b), width=3)
Don't use: Emoji fonts (unreliable across platforms) or assume pre-packaged graphics exist in this skill.
Graphics should look polished and creative, not basic. Here's how:
Use thicker lines - Always set width=2 or higher for outlines and lines. Thin lines (width=1) look choppy and amateurish.
Add visual depth :
create_gradient_background)Make shapes more interesting :
Pay attention to colors :
For complex shapes (hearts, snowflakes, etc.):
Be creative and detailed! A good Slack GIF should look polished, not like placeholder graphics.
core.gif_builder)Assembles frames and optimizes for Slack:
builder = GIFBuilder(width=128, height=128, fps=10)
builder.add_frame(frame) # Add PIL Image
builder.add_frames(frames) # Add list of frames
builder.save('out.gif', num_colors=48, optimize_for_emoji=True, remove_duplicates=True)
core.validators)Check if GIF meets Slack requirements:
from core.validators import validate_gif, is_slack_ready
# Detailed validation
passes, info = validate_gif('my.gif', is_emoji=True, verbose=True)
# Quick check
if is_slack_ready('my.gif'):
print("Ready!")
core.easing)Smooth motion instead of linear:
from core.easing import interpolate
# Progress from 0.0 to 1.0
t = i / (num_frames - 1)
# Apply easing
y = interpolate(start=0, end=400, t=t, easing='ease_out')
# Available: linear, ease_in, ease_out, ease_in_out,
# bounce_out, elastic_out, back_out
core.frame_composer)Convenience functions for common needs:
from core.frame_composer import (
create_blank_frame, # Solid color background
create_gradient_background, # Vertical gradient
draw_circle, # Helper for circles
draw_text, # Simple text rendering
draw_star # 5-pointed star
)
Offset object position with oscillation:
math.sin() or math.cos() with frame indexScale object size rhythmically:
math.sin(t * frequency * 2 * math.pi) for smooth pulseObject falls and bounces:
interpolate() with easing='bounce_out' for landingeasing='ease_in' for falling (accelerating)Rotate object around center:
image.rotate(angle, resample=Image.BICUBIC)Gradually appear or disappear:
Image.blend(image1, image2, alpha)Move object from off-screen to position:
interpolate() with easing='ease_out' for smooth stopeasing='back_out'Scale and position for zoom effect:
Create particles radiating outward:
x += vx, y += vyvy += gravity_constantOnly when asked to make the file size smaller, implement a few of the following methods:
num_colors=48 instead of 128remove_duplicates=True in save()optimize_for_emoji=True auto-optimizes# Maximum optimization for emoji
builder.save(
'emoji.gif',
num_colors=48,
optimize_for_emoji=True,
remove_duplicates=True
)
This skill provides:
It does NOT provide:
Note on user uploads : This skill doesn't include pre-built graphics, but if a user uploads an image, use PIL to load and work with it - interpret based on their request whether they want it used directly or just as inspiration.
Be creative! Combine concepts (bouncing + rotating, pulsing + sliding, etc.) and use PIL's full capabilities.
