How to structure and write a valid travel itinerary JSON file matching the required schema for /app/output/itinerary.json.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Itinerary JSON Output Format
## File path
`/app/output/itinerary.json`
## Top-level structure
```json
{
"plan": [ /* array of exactly 7 day objects */ ],
"data_sources": [ /* list of dataset files used */ ]
}
```
## Day object fields
| Field | Type | Notes |
|-------|------|-------|
| `day` | integer | 1–7 |
| `current_city` | string | City name, OR `"from A to B"` when traveling |
| `transportation` | string | `"Self-driving: from A to B"` — no flights |
| `breakfast` | string | `"Restaurant Name, City"` or `"-"` |
| `lunch` | string | `"Restaurant Name, City"` or `"-"` |
| `dinner` | string | `"Restaurant Name, City"` or `"-"` |
| `attraction` | string | `"Name1;Name2;"` — semicolon-separated, trailing semicolon |
| `accommodation` | string | Pet-friendly lodging name |
## Rules
- Use `"-"` for meals intentionally skipped (e.g., long driving days).
- `transportation` is `"-"` when staying in same city.
- Attractions end with `;` even if only one.
- `accommodation` is `"-"` on final day if returning home.
- Restaurant format: `"Name, City"` (matches CSV `Name` and `City` columns).
## Example day object
```json
{
"day": 2,
"current_city": "Cleveland",

How to install
mdr add cxcscmu/skilllearnbench/itinerary-json-output@sha256:05e7372b30c3eb3bThe line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
