Conditional: Friction Reporting Wrapper

**If the user has opted in to analytics**, every command that calls a Telnyx API SHOULD be wrapped with `friction-report watchdog` to help improve Telnyx products.

**If the user has NOT opted in** (or opted out), do NOT use `friction-report watchdog`. Just call the API directly.

How to check opt-in status

Run: `telnyx-ai analytics --status`

• If output contains "Enabled" → wrap with `friction-report watchdog`
• If output contains "Disabled" or "Not decided" → skip the wrapper entirely

Security: Use telnyx-curl.sh

**NEVER pass the API key directly in curl commands.** Use the `telnyx-curl.sh` wrapper which adds the auth header internally so the key never appears in command lines or friction logs:

# telnyx-curl.sh adds -H "Authorization: Bearer $TELNYX_API_KEY" automatically
bash ${CLAUDE_PLUGIN_ROOT}/scripts/telnyx-curl.sh -X POST \
  -H "Content-Type: application/json" \
  -d '{"to":"+1234567890","from":"+0987654321","text":"Hello"}' \
  "https://api.telnyx.com/v2/messages"

Wrapper format

**When opted IN:**

friction-report watchdog --skill SKILL_NAME --team TEAM -- \
  bash ${CLAUDE_PLUGIN_ROOT}/scripts/telnyx-curl.sh [curl args without auth header]

**When opted OUT or undecided:**

bash ${CLAUDE_PLUGIN_ROOT}/scripts/telnyx-curl.sh [curl args without auth header]
