Analyze animated GIF files by extracting and viewing frames as sequential video. Use when: - User mentions a GIF file path (e.g., "./demo.gif", "~/Downloads/animation.gif") - User wants to analyze or understand a GIF animation - User asks about motion, changes, or content in a GIF - User attaches or references a .gif file for analysis - User wants to examine a screen recording in GIF format - User invokes /gif slash command Keywords: "GIF", ".gif", "animation", "animated", "frames", "screen recording", "analyze gif", "gif analysis", "view gif", "gif content", "gif motion" Trigger patterns: - Natural language: "Analyze this GIF: ./demo.gif" - Slash command: `/gif <path>` or `/gif <path> <message>` When triggered, extract frames using the Python script, view frames in order, and interpret as continuous video sequence.

GIF Analyzer

Analyze animated GIFs by extracting frames and interpreting them as sequential video.

Quick Start

When the user uses

/gif

Pattern 1: Basic analysis

/gif ./animation.gif

Pattern 2: With specific request

/gif ./animation.gif describe what happens step by step
/gif ./demo.gif what is the character doing?
/gif ./screen.gif summarize this screen recording

Workflow

Step 1: Parse User Input

Extract from the user's message:

GIF path: The file path immediately after
```
/gif
```
User request (optional): Any text after the GIF path

Example parsing:

Input:
```
/gif ./demo.gif explain the animation
```
GIF path:
```
./demo.gif
```
User request:
```
explain the animation
```

Step 2: Extract Frames

bash

python3 ~/.claude/skills/gif-analyzer/extract_gif_frames.py <gif_path> --output-dir /tmp/gif_frames_analysis

Options for long GIFs:

bash

python3 ~/.claude/skills/gif-analyzer/extract_gif_frames.py <gif_path> --max-frames 30 --skip 2

Step 3: Read Metadata

Check

gif_metadata.json

for:

Total frames and duration
Individual frame timestamps
Resolution and loop information

Step 4: View and Analyze Frames

View frames in order:

frame_001.png

frame_002.png

, etc.

CRITICAL: Treat frames as a continuous video sequence:

Frame 001 = START of the animation
Frame numbers increase in TIME ORDER
Consecutive frames show MOTION/CHANGE over time

Step 5: Respond to User

If user provided a specific request, focus on answering that. Otherwise, provide a general analysis of the GIF content.

Script Options

Option	Description	Default
`--output-dir` , `-o`	Output directory	`./gif_frames_<timestamp>`
`--max-frames` , `-m`	Max frames to extract	50
`--skip` , `-s`	Extract every Nth frame	1 (all frames)

Frame Analysis Guidelines

Temporal Awareness: Frame 001 is the beginning
Motion Detection: Compare adjacent frames to identify movement
Key Frames: Identify significant moments (start, middle, end)
Loop Points: Note if the animation appears to loop
Duration Context: Use timestamp info to understand pacing

Output Format

📹 **GIF Analysis: [filename]**

**Overview:**
[1-2 sentence summary]

**Timeline:**
- [0.0s - 0.5s] Frame 1-5: [Description]
- [0.5s - 1.0s] Frame 6-10: [Description]
...

**[Answer to user's specific question if provided]**

Troubleshooting

Pillow not found:
```
pip install Pillow
```
Too many frames: Use
```
--skip 2
```
or higher
Large output: Use
```
--max-frames 20
```
