slack-gif-creatorToolkit for creating animated GIFs optimized for Slack, with validators for size constraints and composable animation primitives.
Slack Gif Creator is an agent skill from davepoon/buildwithclaude. Toolkit for creating animated GIFs optimized for Slack, with validators for size constraints and composable animation primitives. This skill applies when users request animated GIFs or emoji animations for Slack from descriptions like "make me a GIF for Slack of X doing Y".
Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files (for example `core/color_palettes.py`, `core/easing.py` and `core/frame_composer.py`).
It sits in Media & Creative, covering Social media graphics. It works with Slack. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit fc03a95. It shows what the files ask for, not the result of running them.
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.
Ships script files (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
pipFrom the folder's file list and the shell code blocks in SKILL.md.
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.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Slack Gif Creator loads about 4.3k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 538 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.
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.

This skill also uses 22 other files; get the full folder from GitHub.A toolkit for creating animated GIFs optimized for Slack. Provides validators for Slack's constraints, composable animation primitives, and optional helper utilities. Apply these tools however needed to achieve the creative vision.
Slack has specific requirements for GIFs based on their use:
Message GIFs:
Emoji GIFs:
Emoji GIFs are challenging - the 64KB limit is strict. Strategies that help:
This skill provides three types of tools:
Complete creative freedom is available in how these tools are applied.
To ensure a GIF meets Slack's constraints, use these validators:
from core.gif_builder import GIFBuilder
# After creating your GIF, check if it meets requirements
builder = GIFBuilder(width=128, height=128, fps=10)
# ... add your frames however you want ...
# Save and check size
info = builder.save('emoji.gif', num_colors=48, optimize_for_emoji=True)
# The save method automatically warns if file exceeds limits
# info dict contains: size_kb, size_mb, frame_count, duration_secondsFile size validator:
from core.validators import check_slack_size
# Check if GIF meets size limits
passes, info = check_slack_size('emoji.gif', is_emoji=True)
# Returns: (True/False, dict with size details)Dimension validator:
from core.validators import validate_dimensions
# Check dimensions
passes, info = validate_dimensions(128, 128, is_emoji=True)
# Returns: (True/False, dict with dimension details)Complete validation:
from core.validators import validate_gif, is_slack_ready
# Run all validations
all_pass, results = validate_gif('emoji.gif', is_emoji=True)
# Or quick check

builder.add_frame(frame)These are optional helpers for common needs. Use, modify, or replace these with custom implementations as needed.
from core.gif_builder import GIFBuilder
# Create builder with your chosen settings
builder = GIFBuilder(width=480, height=480, fps=20)
# Add frames (however you created them)
for frame in my_frames:
builder.add_frame(frame)
# Save with optimization
builder.save('output.gif',
num_colors=128,
optimize_for_emoji=False)Key features:
For small GIFs like emojis, text readability is challenging. A common solution involves adding outlines:
from core.typography import draw_text_with_outline, TYPOGRAPHY_SCALE
# Text with outline (helps readability)
draw_text_with_outline(
frame, "BONK!",
position=(240, 100),
font_size=TYPOGRAPHY_SCALE['h1'], # 60px
text_color=(255, 68, 68),
outline_color=(0, 0, 0),
outline_width=4,
centered=True
)To implement custom text rendering, use PIL's ImageDraw.text() which works fine for larger GIFs.
Professional-looking GIFs often use cohesive color palettes:
from core.color_palettes import get_palette
# Get a pre-made palette
palette = get_palette('vibrant') # or 'pastel', 'dark', 'neon', 'professional'
bg_color = palette['background']
text_color = palette['primary']
accent_color = palette['accent']To work with colors directly, use RGB tuples - whatever works for the use case.
Optional effects for impact moments:
from core.visual_effects import ParticleSystem, create_impact_flash, create_shockwave_rings
# Particle system
particles = ParticleSystem()
particles.emit_sparkles(x=240, y=200, count=15)
particles.emit_confetti(x=240, y=200, count=20)
# Update and render each frame
particles.update()
particles.render(frame)
# Flash effect
frame = create_impact_flash(frame, position=(240, 200), radius=100)
# Shockwave rings
frame = create_shockwave_rings(frame, position=(240, 200), radii=[30, 60, 90])Smooth motion uses easing instead of linear interpolation:
from core.easing import interpolate
# Object falling (accelerates)
y = interpolate(start=0, end=400, t=progress, easing='ease_in')
# Object landing (decelerates)
y = interpolate(start=0, end=400, t=progress, easing='ease_out')
# Bouncing
y = interpolate(start=0, end=400, t=progress, easing='bounce_out')
# Overshoot (elastic)
scale = interpolate(start=0.5, end=1.0, t=progress, easing='elastic_out')Available easings: linear, ease_in, ease_out, ease_in_out, bounce_out, elastic_out, back_out (overshoot), and more in core/easing.py.
Basic drawing utilities if you need them:
from core.frame_composer import (
create_gradient_background, # Gradient backgrounds
draw_emoji_enhanced, # Emoji with optional shadow
draw_circle_with_shadow, # Shapes with depth
draw_star # 5-pointed stars
)
# Gradient background
frame = create_gradient_background(480, 480, top_color, bottom_color)
# Emoji with shadow
