# CLI Reference (`omnigraph`)

A reference for the `omnigraph` binary's command surface and `omnigraph.yaml` schema. For a quick-start guide, see [cli.md](cli.md).

17 top-level command families, 40+ subcommands. All commands accept either a positional `URI`, `--uri`, or a `--target <name>` resolved against `omnigraph.yaml`.

## Top-level commands

| Command | Purpose |
|---|---|
| `init` | `--schema <pg>` → initialize a graph (also scaffolds `omnigraph.yaml` if missing) |
| `load` | bulk load a branch (`--mode overwrite\|append\|merge`) |
| `ingest` | branch-creating transactional load (`--from <base>`) |
| `query` (alias: `read`) | run named read query; source via `--query <path>`, `-e`/`--query-string <GQ>`, or `--alias <name>` (exactly one). `read` is the deprecated previous name and prints a one-line warning to stderr |
| `mutate` (alias: `change`) | run mutation query; same `--query` / `-e` / `--alias` mutual-exclusion as `query`. `change` is the deprecated previous name and prints a one-line warning to stderr |
| `snapshot` | print current snapshot (per-table version + row count) |
| `export` | dump to JSONL on stdout (`--type T`, `--table K` filters) |
| `branch create \| list \| delete \| merge` | branching ops |
| `commit list \| show` | inspect commit graph |
| `run list \| show \| publish \| abort` | transactional run ops |
| `schema plan \| apply \| show (alias: get)` | migrations |
| `lint` (alias: `check`) | offline / graph-backed query validation. Replaces `query lint` / `query check`, which are kept as deprecated argv-level shims that print a one-line warning and rewrite to `omnigraph lint` |
| `queries validate \| list` | operate on the server-side stored-query registry (the `queries:` block). `validate` type-checks every stored query against the live schema offline (opens the selected graph; exits non-zero on any breakage), catching schema drift without restarting the server; `list` prints the selected registry's query names, MCP exposure, and typed params. For per-graph registries, pass `--target <graph>` or set `cli.graph`; with no graph selection, `list` shows only top-level `queries:`. Distinct from `lint`, which validates a single `.gq` file |
| `optimize` | non-destructive Lance compaction (skips tables with `Blob` columns; `--json` reports a `skipped` field) |
| `cleanup --keep N --older-than 7d --confirm` | destructive version GC |
| `embed` | offline JSONL embedding pipeline |
| `policy validate \| test \| explain` | Cedar tooling. Selects `cli.graph`, else `server.graph`, else top-level `policy.file` |
| `version` / `-v` | print `omnigraph 0.3.x` |

## `omnigraph.yaml` schema

```yaml
project: { name }
graphs:
  <name>:
    uri: <local|s3://|http(s)://>
    bearer_token_env: <ENV_NAME>
    queries:                      # per-graph stored-query registry (server-role; multi-graph mode)
      <query-name>:               # key MUST equal the `query <name>` symbol inside the .gq
        file: <path-to-.gq>       # relative to this config's directory
        mcp:
          expose: true            # default true: listed in the MCP catalog (GET /queries); set false to hide (still HTTP-callable)
          tool_name: <name>       # optional MCP tool-name override (defaults to <query-name>;
                                  #   must be unique across exposed queries)
server:
  graph: <name>
  bind: <ip:port>
cli:
  graph: <name>
  branch: <name>
  output_format: json|jsonl|csv|kv|table
  table_max_column_width: 80
  table_cell_layout: truncate|wrap
query:
  roots: [<dir>, …]   # search path for .gq files
auth:
  env_file: ./.env.omni
aliases:
  <alias>:
    # accepted values: `read` / `query` (read alias), `change` / `mutate`
    # (write alias). `query` and `mutate` are recommended; `read` and
    # `change` remain accepted forever for back-compat.
    command: read|change|query|mutate
    query: <path-to-.gq>
    name: <query-name>
    args: [<positional-name>, …]
    graph: <name>
    branch: <name>
    format: <output-format>
queries:                          # top-level registry — applies only to a bare-URI (anonymous) graph; a graph served by name uses its `graphs.<id>.queries`. Mirrors top-level `policy`.
  <query-name>: { file: <path-to-.gq> }   # mcp.expose defaults to true
policy:
  file: ./policy.yaml
```

## Output formats (`query` command, alias: `read`)

- `json` — pretty-printed object with metadata + rows
- `jsonl` — one metadata line then one JSON object per row
- `csv` — RFC 4180-ish quoting
- `table` — fitted text table, honors `table_max_column_width` + `table_cell_layout`
- `kv` — grouped per-row key/value blocks

## Param resolution

Precedence (high to low): explicit `--params` / `--params-file`, alias positional args, `omnigraph.yaml` defaults. JS-safe-integer handling is built in (`is_js_safe_integer_i64`, `JS_MAX_SAFE_INTEGER_U64`) so 64-bit ids round-trip safely through JSON clients.

## Bearer token resolution (CLI)

1. `graphs.<name>.bearer_token_env`
2. `OMNIGRAPH_BEARER_TOKEN` global env
3. `auth.env_file` referenced `.env`

## Duration parsing (cleanup)

`s | m | h | d | w` units, e.g. `--older-than 7d`.
