Test Twilio Content Templates with Codex and Fake Values

Prepare template variants and validate placeholder inputs in a scratch project before any submission or send.

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-content-template-builder and paste the example inputs. Use the installed package with its related skills and references.

Example task

Give $twilio-content-template-builder a reminder template with placeholders for class and start time. Run one local substitution with Robotics and 18:30 and one with the time missing. Treat channel approval metadata as a separate report field.

Expected result

The first output contains Robotics and 18:30. The second returns a missing-time error and emits no template. The plan identifies which channel approval step to confirm.

Frequently asked question

Can a passed local render mean the template is approved?

Rendering checks your variables and layout. The channel provider's documented review process determines approval for the intended use.
