Description
Telnyx — voice, SMS/MMS messaging, SIP trunking, number management, and fax.
Usage Guidance
This skill is internally consistent for interacting with Telnyx and only asks for TELNYX_API_KEY. Before installing: 1) Verify you want the skill to call api.telnyx.com and provide a Telnyx API key. Use a key with least privilege. 2) Note the script will try a fallback .env lookup in WORKSPACE or ~/.openclaw/workspace if the env var is missing — ensure no sensitive keys are unintentionally stored there. 3) Expect some CLI commands to fail due to an argument-name bug (the code references args attributes that argparse sets under different names); review or test the script locally before using in production. 4) If you plan to let the agent invoke skills autonomously, remember this skill can initiate outbound Telnyx actions (send messages, calls, order numbers) whenever called — limit API key permissions and monitor usage.
Capability Analysis
Type: OpenClaw Skill
Name: telnyx
Version: 1.0.0
The Telnyx skill bundle is a standard API wrapper for voice, SMS, and number management services. The Python script (scripts/telnyx.py) uses only the standard library to interact with the official Telnyx API (api.telnyx.com) and handles the required API key through environment variables or a local .env file. No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description, required env var (TELNYX_API_KEY), and code all target Telnyx REST API (https://api.telnyx.com/v2). The requested credential is appropriate for the stated functionality (SMS, calls, numbers, faxes).
Instruction Scope
Runtime instructions show running the included CLI script. The script will attempt to read TELNYX_API_KEY from the environment and, if absent, will try to read a .env file from WORKSPACE or ~/.openclaw/workspace — this fallback isn't documented in SKILL.md. Also there are coding bugs: many command handlers check getattr(args,'from') but argparse uses dest='from_addr' so those commands will fail unless args attribute names are fixed; this is a functionality bug rather than a hidden behavior.
Install Mechanism
No install spec or external downloads — instruction-only skill with a small Python stdlib-only script included. Nothing is fetched from external or untrusted URLs during install.
Credentials
Only TELNYX_API_KEY is required (declared as primary credential) which is proportionate. The script's fallback to reading a .env file in WORKSPACE or ~/.openclaw/workspace may access stored keys in that file — it only parses the requested variable name, but you should be aware it looks for credentials in that local .env file if the env var is missing.
Persistence & Privilege
always is false and the skill does not modify other skills or system-wide settings. It does not persist secrets or enable itself automatically.
How to Use
- Make sure OpenClaw is installed (local or Docker)
