That the good ones do one job, with the constraints already known.

## Short answer
The slack-gif-creator skill produces animated GIFs sized and formatted for Slack. It is genuinely useful for internal culture, and it is more valuable as a worked example: a skill that knows one output format, its constraints and its edge cases, which is what separates useful skills from documentation.

Best for: Team culture, internal celebrations, and studying what a well scoped skill looks like.
Skip it if: You need production video or brand assets, which is different work entirely.

## What to remember
- Narrow scope is a feature. The skill knows one target and its limits.
- Format constraints encoded once beat rediscovering them every time.
- It is the shortest useful example to read before writing your own skill.
- Low stakes output is a good place to learn how skills behave.

## What it changes in practice
Making a GIF that Slack renders properly means knowing size limits, dimensions and frame rate. Those are exactly the boring constraints people look up, get slightly wrong and look up again.
Encoding them once is the entire value, and it generalises: the best skills you will write are usually the ones that capture constraints you keep rediscovering.

## Where it disappoints
It is deliberately limited. Complex animation, brand work and video are outside its scope and should stay there.
Humour also does not transfer. The technical output can be perfect and the joke can still be flat, which no skill will fix.

## Install and first run
1. Install it from anthropics/skills under Apache 2.0.
2. Describe the motion and the punchline, not the file settings.
3. Read the skill source afterwards, and notice how much of it is constraints rather than instructions.

## Questions
### Is this a serious skill?
Yes, for internal culture, and it is also the clearest small example of good skill design.

### Why does its narrowness matter?
Because it shows that useful skills encode constraints for one job rather than describing a topic broadly.

### Can it make video?
No. It targets Slack ready animated GIFs, and stretching it beyond that is the wrong tool.
