What it does

Gif Generation is an agent skill from athola/claude-night-market. Converts webm/mp4 video files to optimized GIFs via ffmpeg with configurable quality settings. Use when post-processing recordings into shareable GIFs.

Its SKILL.md is about 1.4k 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 Media & Creative, covering Video production and Social media graphics. It works with FFmpeg. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 9f3eb00. 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.

Runs code
Shell commands in SKILL.md call:

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

Gif Generation loads about 1.4k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 372 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~42
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteRuns commands with sudoSKILL.md:75

echo "Install with: sudo apt install ffmpeg (Linux) or brew install ffmpeg (macOS)"

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.

GIF Generation Skill

Post-process video files (webm/mp4) and generate optimized GIF output with configurable quality settings.

When To Use

Converting recordings to animated GIF format
Creating lightweight demo animations

When NOT To Use

High-quality video output - use full recording tools
Static image generation without animation needs

Overview

This skill handles the conversion of video recordings (typically from browser automation) to GIF format. It provides multiple quality presets and optimization options to balance file size with visual quality.

Required TodoWrite Items

- Validate input video file exists
- Check ffmpeg installation
- Execute GIF conversion
- Verify output and report results

Verification: Run the command with --help flag to verify availability.

Process

Step 1: Validate Input File

Confirm the source video file exists and is a supported format:

bash

# Check file exists and get info
if [[ -f "$INPUT_FILE" ]]; then
    file "$INPUT_FILE"
    ffprobe -v quiet -show_format -show_streams "$INPUT_FILE" 2>/dev/null | head -20
else
    echo "Error: Input file not found: $INPUT_FILE"
    exit 1
fi

Verification: Run the command with --help flag to verify availability.

Supported input formats: .webm, .mp4, .mov, .avi

Step 2: Check ffmpeg Installation

Verify ffmpeg is available:

bash

if ! command -v ffmpeg &> /dev/null; then
    echo "Error: ffmpeg is not installed"
    echo "Install with: sudo apt install ffmpeg (Linux) or brew install ffmpeg (macOS)"
    exit 1
fi
ffmpeg -version | head -1

Verification: Run the command with --help flag to verify availability.

Step 3: Execute Conversion

Choose the appropriate conversion command based on quality requirements:

Basic Conversion (Fast, Larger File)

bash

ffmpeg -i input.webm -vf "fps=10,scale=800:-1" output.gif

Verification: Run the command with --help flag to verify availability.

High Quality with Palette Generation (Recommended)

bash

ffmpeg -i input.webm -vf "fps=10,scale=800:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" output.gif

Verification: Run the command with --help flag to verify availability.

Maximum Quality with Dithering

bash

ffmpeg -i input.webm -vf "fps=15,scale=1024:-1:flags=lanczos,split[s0][s1];[s0]palettegen=max_colors=256:stats_mode=single[p];[s1][p]paletteuse=dither=bayer:bayer_scale=5" output.gif

Verification: Run the command with --help flag to verify availability.

Optimization Options

Option	Description	Recommended Value
`fps`	Frames per second	10-15 for smooth, 5-8 for smaller files
`scale`	Width in pixels (-1 maintains aspect ratio)	800 for web, 480 for thumbnails
`flags=lanczos`	High-quality scaling algorithm	Always use for best quality
`palettegen`	Generate optimized color palette	Use for quality-critical output
`dither`	Dithering algorithm	`bayer` for patterns, `floyd_steinberg` for smooth

Common Presets

bash

# Thumbnail (small, fast loading)
ffmpeg -i input.webm -vf "fps=8,scale=480:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" thumbnail.gif

# Documentation (balanced)
ffmpeg -i input.webm -vf "fps=10,scale=800:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" docs.gif

# High-fidelity demo
ffmpeg -i input.webm -vf "fps=15,scale=1024:-1:flags=lanczos,split[s0][s1];[s0]palettegen=max_colors=256[p];[s1][p]paletteuse" demo.gif

Verification: Run the command with --help flag to verify availability.

Step 4: Verify Output

Confirm successful conversion and report metrics:

bash

if [[ -f "$OUTPUT_FILE" ]]; then
    echo "GIF generated successfully: $OUTPUT_FILE"

    # Report file size
    SIZE=$(du -h "$OUTPUT_FILE" | cut -f1)
    echo "File size: $SIZE"

    # Get dimensions and frame count
    ffprobe -v quiet -select_streams v:0 -show_entries stream=width,height,nb_frames -of csv=p=0 "$OUTPUT_FILE"
else
    echo "Error: GIF generation failed"
    exit 1
fi

Verification: Run the command with --help flag to verify availability.

Exit Criteria

Input file validated as existing video format
ffmpeg confirmed available
GIF file created at specified output path
Output file size reported to user
No ffmpeg errors during conversion

Troubleshooting

Large Output File

Reduce quality settings:

bash

# Lower fps and resolution
ffmpeg -i input.webm -vf "fps=8,scale=640:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" smaller.gif

Verification: Run the command with --help flag to verify availability.

Color Banding

Use dithering:

bash

ffmpeg -i input.webm -vf "fps=10,scale=800:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse=dither=floyd_steinberg" smooth.gif

Verification: Run the command with --help flag to verify availability.

Slow Conversion

Use basic conversion without palette generation for speed:

bash

ffmpeg -i input.webm -vf "fps=10,scale=800:-1" quick.gif

Verification: Run the command with --help flag to verify availability.
