# stmo-cli
## How it works
stmo-cli is a CLI that Claude Code calls on your behalf. Install it, set your API key, and Claude Code can:
- **Explore** — discover data sources, find existing queries, browse schemas
- **Write** — create new Redash queries with proper BigQuery SQL
- **Deploy** — push queries, charts, and dashboards to STMO
- **Execute** — run queries and inspect results
- **Analyze** — export data for deeper analysis with other tools
For example, ask Claude Code to:
- "Find queries about Firefox DAU"
- "Write a query to track [metric] over time"
- "Fetch and run query #12345"
- "Explore what telemetry tables are available"
Pair it with the [mozdata plugin](https://github.com/mozilla/internal-aidev-plugins/tree/main/plugins/mozdata) for telemetry expertise and probe discovery.
## Prerequisites
- Redash API key from https://sql.telemetry.mozilla.org
## Installation
### For people who already have the Firefox source stored locally
```
cd /path/to/your/firefox/source/folder
./mach bootstrap
```
### For anyone else
Install [cargo-binstall](https://docs.rs/crate/cargo-binstall/latest).
```
cargo binstall stmo-cli
```
### Build from source:
```bash
cargo build --release
# The binary will be at ./target/release/stmo-cli
```
## Setup
1. Get your Redash API key from your user profile
2. Provide the key:
**On macOS**, run this once in your own terminal (not through Claude Code, which has no
terminal to prompt in):
```bash
stmo-cli login
```
This stores the key encrypted in the macOS Keychain (service `stmo-cli`) and reads it
back automatically from then on — every Claude Code session, every worktree, no env var,
no manual export. The first `stmo-cli login` (or the first command run with no key set,
if you're in a terminal) prompts you for the key with a hidden `security` prompt; grant
"Always Allow" once when macOS asks, and later reads are silent.
**On other platforms**, or if you'd rather manage it yourself, set the environment
variable directly:
```bash
export REDASH_API_KEY="your-api-key-here"
export REDASH_URL="https://sql.telemetry.mozilla.org" # optional, this is the default
```
`REDASH_API_KEY` always takes precedence over the Keychain when set.
For Mozilla, the key can be accessed via the following URL: https://sql.telemetry.mozilla.org/users/me
3. Create directories:
```bash
stmo-cli init
```
4. Discover available queries:
```bash
stmo-cli discover stmo-cli discover --search "firefox dau" ```
5. Fetch specific queries:
```bash
stmo-cli fetch 123 456 789
```
## Usage
### Fetch Queries from Redash
```bash
stmo-cli fetch --all # Fetch all tracked queries
stmo-cli fetch 123 456 789 # Fetch specific queries
stmo-cli discover # List your own queries
stmo-cli discover --search "firefox dau" # Full-text search queries + dashboards (--limit, default 50)
```
This creates/updates:
- `queries/{id}-{slug}.sql` - Query SQL
- `queries/{id}-{slug}.yaml` - Query metadata (parameters, visualizations, etc.)
### Deploy to Redash
```bash
stmo-cli deploy # Deploy changed queries (detected via git status)
stmo-cli deploy --all # Deploy all queries
```
**Warning**: This force overwrites the queries in Redash. Git is the source of truth.
### Execute Queries
```bash
stmo-cli execute 123 # Run query 123 (deploys local changes first, if any)
stmo-cli execute 123 --param start_date=2026-06-15
stmo-cli execute 123 --param channels='["release","beta"]' # Multi-value enum as JSON
stmo-cli data-sources # List data sources
```
`execute ID` deploys the local `.sql`/`.yaml` first if it differs from what's stored on the
server (SQL, name, data source, or parameters), so it never silently runs a stale copy — then
it always runs the up-to-date server-stored query.
`execute --data-source ID` runs ad-hoc SQL directly against a data source without creating a
tracked query — useful for one-off exploration. It has no parameter schema, so multi-value
parameters can't be expanded for you — inline the values directly in the SQL (e.g.
`IN ('release', 'beta')`).
Parameters are passed as `--param name=value` (repeatable). Values are parsed as JSON when
possible, anything that isn't valid JSON is treated as a plain string.
### Manage Query Snippets
```bash
stmo-cli snippets list # List query snippets from Redash
stmo-cli snippets fetch 31 42 # Fetch specific snippets
stmo-cli snippets fetch --all # Fetch all tracked snippets
stmo-cli snippets deploy # Deploy changed snippets (detected via git status)
stmo-cli snippets deploy --all # Deploy all snippets
stmo-cli snippets delete 31 42 # Delete snippets in Redash and remove local files
```
Snippets don't have an archive concept in Redash — `snippets delete` removes the snippet on
the server and deletes the local files in one step; there's no separate `--cleanup` flag.
## File Structure
```
queries/
├── 123-mobile-crashes.sql
└── 123-mobile-crashes.yaml
dashboards/
└── 456-my-dashboard.yaml
snippets/
├── 31-reviewbot_e2e_action_ctcs.sql
└── 31-reviewbot_e2e_action_ctcs.yaml
```
Query IDs are embedded in filenames (`{id}-{slug}.{ext}`), so no separate config file is needed.
Snippet filenames use `{id}-{trigger}.{ext}` (Redash snippets are keyed by `trigger`, not `name`).
## Development
### Pre-commit Hooks
The project uses clippy in pedantic mode:
```bash
cargo clippy --all-targets --all-features -- -W clippy::pedantic -D warnings
```
Install pre-commit hooks:
```bash
pip install pre-commit
pre-commit install
```
### Building for Release
```bash
cargo build --release
./target/release/stmo-cli --help
```
