Plan Twilio RCS Messaging in Codex with a Fallback Test
Draft an RCS message experience and check how the app chooses a simple fallback when a test recipient lacks RCS capability.
中文Setup for Codex (Twilio Developer Kit)
Use Codex in a scratch workspace. The exercise takes local mock data or a written scenario. Check provider prerequisites before running it against a test account.
- In Codex, open /plugins and install Twilio Developer Kit. To reproduce the exact revision, use the pinned Twilio source linked below and its Codex instructions in the repository README.
- Open the practice project, invoke $twilio-rcs-messaging and paste the example inputs. Use the installed package with its related skills and references.
Example task
Use $twilio-rcs-messaging with a fictional appointment reminder. Feed local capability fixtures true and false and render a rich card for true and a plain SMS placeholder for false. Hold both outputs in a fake outbox.Expected result
The rich card contains appointment time and one action. The fallback includes the appointment time only. Both are captured by the outbox, without sending messages.

Frequently asked question
Can this fixture verify carrier availability?
It verifies your selection logic and rendered content. Check active sender setup and support for the destination in Twilio before an opt-in sandbox test.
