Wraps the Cargo CLI for managing data models, datasets, columns, and relationships in your workspace storage. You get commands to list models, inspect DDL schemas, create columns, set relationships between tables, and run SQL queries against storage using friendly dataset.model syntax that rewrites to the actual storage layer. The preview workflow is smart: after creating a model or column, it shows schema first (since new models are empty), then switches to showing actual rows once data lands. Useful when you need to understand what's already in your workspace, build out a data model programmatically, or run SQL without worrying about underlying table names.

See ../cargo/references/prerequisites.md for install, login (--oauth / --token), JSON output conventions, and error shapes. Verify the session with cargo-ai whoami before running any of the commands below.
Always list before inspecting or modifying.
cargo-ai storage dataset list # all datasets (uuid, slug)
cargo-ai storage model list # all models (uuid, name, slug, columns)
cargo-ai storage model list --dataset-uuid <uuid> # models in a specific dataset
Retrieve in the UI: models live at app.getcargo.io/workspaces/<WORKSPACE_UUID>/models/<MODEL_UUID>. Get <WORKSPACE_UUID> from cargo-ai whoami under workspace.uuid.
cargo-ai storage model list
cargo-ai storage model get <model-uuid>
cargo-ai storage model get-ddl <model-uuid>
cargo-ai storage dataset list
cargo-ai storage column list --model-uuid <uuid>
cargo-ai storage relationship list --model-uuid <uuid>
cargo-ai storage record list --model-uuid <uuid>
cargo-ai storage query execute "SELECT * FROM default.companies LIMIT 10"
cargo-ai storage query download --query "SELECT * FROM default.companies"
Models are structured tables in your workspace (e.g. Companies, Contacts).
# List all models
cargo-ai storage model list
# List models in a dataset
cargo-ai storage model list --dataset-uuid <uuid>
# Get a single model (includes columns)
cargo-ai storage model get <model-uuid>
# Get the DDL (full schema, table name and SQL dialect)
cargo-ai storage model get-ddl <model-uuid>
# → Useful for column discovery and SQL dialect (BigQuery vs Snowflake) before writing queries
# Create a model
cargo-ai storage model create \
--slug contacts \
--name "Contacts" \
--dataset-uuid <uuid> \
--extractor-slug <extractor-slug> \
--config '{}'
# Update a model
cargo-ai storage model update --uuid <model-uuid> --name "New Name"
# Remove a model
cargo-ai storage model remove <model-uuid>
Querying: Use cargo-ai storage query execute "<sql>" (or storage query download --query "<sql>" for full exports) to run SQL against storage. Tables are referenced as <datasetSlug>.<modelSlug> (e.g. default.companies) and rewritten to the underlying storage table under the hood. See Query with SQL below.
Datasets are logical groupings of models.
# List all datasets
cargo-ai storage dataset list
# Get a single dataset
cargo-ai storage dataset get <dataset-uuid>
Columns define the schema of a model.
# List columns for a model
cargo-ai storage column list --model-uuid <uuid>
# Create a column
cargo-ai storage column create \
--model-uuid <uuid> \
--column '{"slug":"my_column","type":"string","label":"My Column","kind":"custom"}'
# Update a column (pass the full column object — columns are identified by slug, not UUID)
cargo-ai storage column update \
--model-uuid <uuid> \
--column '{"slug":"my_column","type":"string","label":"Updated Label","kind":"custom"}'
# Remove a column
cargo-ai storage column remove --model-uuid <uuid> --column-slug <slug>
# Reorder a column (move to a specific index)
cargo-ai storage column reorder --model-uuid <uuid> --column-slug <slug> --to-index 2
Column types: string, number, boolean, date, object, array, vector, any.
Column kinds: custom (user-defined), computed (expression over other columns), metric (aggregated from a related model), lookup (single field pulled from a related model via a join).
A column list doesn't tell the user whether the model is right — rows do. Two checkpoints (the pack-wide convention lives in ../cargo/references/interaction.md §4):
1. Right after model create / column create — show the schema, not rows. A new model is empty; a LIMIT 10 here returns nothing and reads as failure. Echo the columns as a compact table instead (column, type, what will fill it).
2. As soon as data lands — show the rows. After a batch, play, or import writes into the model, preview it:
cargo-ai storage query execute \
"SELECT * FROM <dataset-slug>.<model-slug> LIMIT 10"
Show ~10 rows and only the columns that carry meaning. Storage queries are free, so this costs nothing but a few lines of output — and it's the first moment the user can actually see what they built. When a play fills a new column, preview that column next to the record's identifying fields (name, domain) so filled vs. empty is obvious.
If the preview comes back empty or all-null when it shouldn't, that's a finding — surface it rather than reporting the write as a success. See cargo-diagnostics to trace why.
Relationships link models together (e.g. Contacts belong to Companies).
# List relationships for a model
cargo-ai storage relationship list --model-uuid <uuid>
# Set a relationship between two models
cargo-ai storage relationship set \
--from-model-uuid <uuid> \
--to-model-uuid <uuid>
# List records in a model
cargo-ai storage record list --model-uuid <uuid>
For advanced record queries (filtering, sorting, pagination), use segmentation segment fetch from the cargo-orchestration skill.
Run SQL against workspace storage with storage query execute. Tables are referenced as <datasetSlug>.<modelSlug> (e.g. default.companies) and rewritten to the underlying storage table under the hood — no DDL lookup is needed for the table name.
cargo-ai storage query execute \
"SELECT name, domain FROM default.companies LIMIT 10"
# → { "rows": [...] } on success; non-zero exit with { "errorMessage": "..." } on error
For full exports, use storage query download — it returns a signed URL to a CSV (default) or Parquet file:
cargo-ai storage query download \
--query "SELECT name, domain, revenue FROM default.companies ORDER BY revenue DESC"
cargo-ai storage query download \
--query "SELECT * FROM default.companies" --format parquet
Get column slugs from storage column list --model-uuid <uuid> (or run storage model get-ddl <model-uuid> for the full schema and SQL dialect). Page through large result sets with LIMIT / OFFSET directly in the SQL.
See references/examples/queries.md for WHERE clauses, aggregations, joins, date queries, pagination, and the failure shapes returned on error.
