cp -r ditto-content-marketing ~/.claude/skills/
```

## API Key Setup


Get a free Ditto API key (no credit card, no sales call):



```
curl -sL https://app.askditto.io/scripts/free-tier-auth.sh | bash
```



Or visit: [https://app.askditto.io/docs/free-tier-oauth](https://app.askditto.io/docs/free-tier-oauth)



Set it as an environment variable:



```
export DITTO_API_KEY="rk_free_YOUR_KEY_HERE"
```



Free keys (`rk_free_`): ~12 shared personas, no custom demographic filters. Paid keys (`rk_live_`): 300,000+ personas, full demographic filtering, unlimited studies.



## How It Works


Just ask Claude Code to do research. The skill activates automatically:



```
"Write a research-backed blog article about how US consumers feel about AI-powered customer service. 10 personas, SEO optimised."

"Generate a social media thread from our latest Ditto study with the 3 most quotable findings."

"Set up a content calendar: one research article per week across 4 different topics."
```



Or invoke directly:



```
/ditto-content-marketing "your research brief here"
```



## Troubleshooting


### Skill not activating


Check it's in the right directory:


- Personal: `~/.claude/skills/ditto-content-marketing/SKILL.md`

- Project: `.claude/skills/ditto-content-marketing/SKILL.md`


Verify with: `ls ~/.claude/skills/ditto-content-marketing/SKILL.md`



You can also invoke manually: `/ditto-content-marketing`



### API key not found


Ensure your key is set: `echo $DITTO_API_KEY`



If using a .env file, make sure Claude Code can read it.



### State filter returning 0 personas


Use 2-letter codes: `MI` not `Michigan`, `TX` not `Texas`.



### Questions failing


Questions must be asked one at a time. Poll one `job_id` until `finished` before asking the next question (all jobs from the same question complete simultaneously, so polling one is sufficient). Wait 45-50 seconds before the first poll.
