### The `.md` convention

Append `.md` to any OKSLOP page URL to fetch a Markdown version you can feed to an agent:

- Brief:       https://okslop.com/briefs/{id}.md
- Photo:       https://okslop.com/image/{slug}.md
- Contributor: https://okslop.com/@{slug}.md

### CLI

```sh
# By keyword
npx okslop search "sunset on basalt" -n 5

# Scoped to one contributor (use their slug from a .md page)
npx okslop search "sunset on basalt" --contributor bob -n 10

# JSON output for scripting
npx okslop search "sunset" --json

# Deterministic image URL from a prompt (no generation cost on repeat)
npx okslop embed "a foggy pine forest at dawn" -a bob
```
