telnyx-acp create scaffolds one directory per agent, named after it. For support-agent:
agent.json is edited by telnyx-acp add, remove, set and unset, or by hand followed by validate; instructions.md is edited by hand. Neither holds a secret value: add secret stores the value on the platform and records only the name.
What the CLI Adds
.telnyx/ is gitignored from the start; agent.json and instructions.md are the project, and are what to commit.
