Flight Goat — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the flight-goat-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

Install via the Printing Press installer:
npx -y @mvanhorn/printing-press install flight-goat --cli-only

Verify: flight-goat-pp-cli --version

Ensure $GOPATH/bin (or $HOME/go/bin) is on $PATH.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.3 or newer):
go install github.com/mvanhorn/printing-press-library/library/travel/flight-goat/cmd/flight-goat-pp-cli@latest

If --version reports "command not found" after install, the install step did not put the binary on $PATH. Do not proceed with skill commands until verification succeeds.

Categories

AeroAPI is divided into several categories to make things easier to
discover.

Flights: Summary information, planned routes, positions and more

Foresight: Flight positions enhanced with FlightAware Foresight™

Airports: Airport information and FIDS style resources

Operators: Operator information and fleet activity resources

Alerts: Configure flight alerts and delivery destinations

History: Historical flight access for various endpoints

Miscellaneous: Flight disruption, future schedule information, and aircraft owner information

Google Flights Currency

Use --currency <ISO-4217-code> when the user wants Google Flights prices in a
specific currency. Omit it for the default USD behavior.

flight-goat-pp-cli flights MAN AGP 2026-05-10 --currency GBP --sort cheapest --agent
flight-goat-pp-cli dates JFK CDG --from 2026-07-01 --to 2026-07-31 --currency EUR --sort --agent
flight-goat-pp-cli compare SEA LHR 2026-06-15 --currency GBP --agent

The flag is only valid on Google Flights price commands: flights, dates,
compare, gf-search, and cheapest-longhaul. Do not add it to AeroAPI or
Kayak-only commands.

Development Tools

AeroAPI is defined using the OpenAPI Spec 3.0, which means it can be easily
imported into tools like Postman. To get started try importing the API
specification using
Postman's instructions.
Once imported as a collection only the "Value" field under the collection's
Authorization tab needs to be populated and saved before making calls.

The AeroAPI OpenAPI specification is located at:

https://flightaware.com/commercial/aeroapi/resources/aeroapi-openapi.yml

Our open source AeroApps project
provides a small collection of services and sample applications to help
you get started.

The Flight Information Display System (FIDS) AeroApp is an example of a
multi-tier application using multiple languages and Docker containers.
It demonstrates connectivity, data caching, flight presentation, and leveraging flight maps.

The Alerts AeroApp demonstrates the use of AeroAPI to set, edit, and
receive alerts in a sample application with a Dockerized Python backend
and a React frontend.

Our AeroAPI push notification testing interface
provides a quick and easy way to test the delivery of customized alerts via AeroAPI push.

alerts — AeroAPI alerting can be used to configure and receive real-time alerts on key flight
events. With customizable alerting offered by our alert endpoints, AeroAPI empowers
users to selectively pick various types of events/filters to alert on. By doing so,
you can receive specially tailored alerts delivered to you for events such as flight plan
filed, flight departure (out and off), flight arrival (on and in), and more!

To get started with alerting, the PUT /alerts/endpoint endpoint must first be used
to set up the account-wide default URL that alerts will be delivered to. This step must
be done before any alerts can be configured and will serve as the fallback URL that all
alerts will be sent to for the account if a specific delivery URL is not designated on a
particular alert. If this is not performed before configuring alerts, then you will
receive a 400 error with an error message reminding you of this step when trying to interact
with the POST /alerts endpoint. Once a URL is set via the PUT /alerts/endpoint endpoint,
then alerts can be configured using the POST /alerts endpoint. The GET /alerts endpoint
can also be used to retrieve all currently configured alerts associated with your AeroAPI key.
The GET /alerts endpoint will allow you to easily retrieve the id of any specific alerts of
interest configured for the account which can let you use the GET PUT and DELETE
/alerts/{id} endpoints to retrieve, update, and delete specific alerts.

When configuring an individual alert, the target_url field can be set to a URL that’s
different than the account-wide target endpoint set via the PUT /alerts/endpoint. If
the target_url field is set on an alert, then that specific alert will be delivered to
the specified target_url rather than the default account-wide one. If this field is not
configured for the alert, then the alert will be delivered to the default account-wide endpoint.
By setting this field, one can easily target different alerts to be received by different endpoints
which can be useful for configuring per-application alerts or sending alerts to an alternate
development environment without having to adjust a production alert configuration.

For each alert configured, one-to-many ‘events’ can be set for alert delivery. While most
events will result in one alert delivery, both the arrival and the departure events can
result in multiple alerts delivered (referred to as bundled). The departure event bundles the
departure (actual OFF the ground) alert, along with the flight plan filed alert and up to 5
per-departure changes which can include alerts for significant departure delays of over
30 minutes, gate changes, and airport delays. FlightAware Global customers will
also receive Power on and Ready to taxi alerts as part of the departure bundle. The arrival event
bundles the arrival (actual ON the ground) alert, along with up to 5 en-route changes (including delays
of over 30 minutes and excluding diversions) identified. FlightAware Global customers will also receive
taxi stop times as part of the arrival bundle. Setting a bundled type and unbundled type for an
On/Off will only result in a single alert in the case where events may overlap.

If there is a need to change the alert configurations, updating an alert using the PUT /alerts/{id}
endpoint and a unique alert identifier (id) is preferred rather than creating an additional alert.
By doing so, you can avoid duplicate alerts being delivered which could create unnecessary noise
if they are not of interest anymore.

If at any point there is a need to delete an alert, the DELETE alerts/{id} endpoint can be
leveraged to delete an alert so that it won’t be delivered anymore. As a reminder, specific alert
IDs can be retrieved from the GET /alerts endpoint.

foresight — Foresight endpoints provide access to FlightAware's Foresight predictive models and
predictions for key events. Our advanced machine learning (ML) models identify key
influencing factors for a flight to forecast future events in real-time, providing
unprecedented insight to improve operational efficiencies and facilitate better
decision-making in the air and on the ground. To learn more about the power of Foresight,
visit https://www.flightaware.com/commercial/foresight/

These endpoints each mirror a non-Foresight equivalent endpoint of similar functionality,
with the addition of all the ML 'predicted' values included in the Foresight response. The
respective non-Foresight endpoint response includes a flag, 'foresight_predictions_available',
which can optionally be used as a trigger to obtain and leverage Foresight predictions on an
as-needed basis and manage cost. Foresight is only available to Premium tier customers.
Contact integrationsales@flightaware.com for more information, pricing details, and to have
your account enabled for Foresight.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

flight-goat-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Auth Setup

Set your API key via environment variable:

export FLIGHT_GOAT_API_KEY_AUTH="<your-key>"

Or persist it in ~/.config/flight-goat-pp-cli/config.toml.

Run flight-goat-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

Pipeable — JSON on stdout, errors on stderr

Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

flight-goat-pp-cli airports get mock-value --agent --select id,name,status

Previewable — --dry-run shows the request without sending

Offline-friendly — sync/search commands can use the local SQLite store when available

Non-interactive — never prompts, every input is a flag

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Flight booking URLs

Each result from flights carries booking_urls for one-tap booking handoff:

{
  "booking_urls": {
    "primary": "https://www.delta.com/flightsearch/book-a-flight?...",
    "primary_kind": "prefill",
    "airline_url": "https://www.delta.com/flightsearch/book-a-flight?...",
    "airline_kind": "prefill",
    "google_url": "https://www.google.com/travel/flights/search?tfs=..."
  }
}

primary is the recommended single URL. Click once, land on a booking surface.

primary_kind tells you what to call it:

prefill — airline form pre-filled with route + dates. Render as "Book on ".

landing — airline booking page; user may need to retype dates. Render as "Open  booking".

search — Google Flights search executed with the user's query. Render as "View on Google Flights".

airline_url and airline_kind are present only when the itinerary is operated end-to-end by a single carrier in the curated table (~35 carriers, see internal/gflights/testdata/airline_url_captures.md). Codeshare itineraries and unknown carriers omit these.

google_url is always populated.

If you only render one URL, render primary and use primary_kind to pick the call-to-action text.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

flight-goat-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
flight-goat-pp-cli feedback --stdin < notes.txt
flight-goat-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.flight-goat-pp-cli/feedback.jsonl. They are never POSTed unless FLIGHT_GOAT_FEEDBACK_ENDPOINT is set AND either --send is passed or FLIGHT_GOAT_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Sink
Effect

stdout
Default; write to stdout only

file:<path>
Atomically write output to <path> (tmp + rename)

webhook:<url>
POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

flight-goat-pp-cli profile save briefing --json
flight-goat-pp-cli --profile briefing airports get mock-value
flight-goat-pp-cli profile list --json
flight-goat-pp-cli profile show briefing
flight-goat-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
