Automated summary

This skill sends and inspects Twilio SMS messages from the terminal through the "uni" CLI, using Twilio account credentials.

Strengths

Short, readable commands for sending an SMS or listing recent messages
Built-in credential handling (configure, check status, log out) with an environment-variable fallback
Message details retrievable by SID, and a -f flag to override the sender number
Deliberately narrow scope, so it is easy to pick up

Limitations

Assumes the "uni" CLI is already installed and available on the PATH
Requires an active Twilio account with a valid sender number, which incurs per-message costs
No inbound messages, MMS, or message templates are covered

When to use it

Use it when you need to notify someone by SMS or check the delivery status of a message from the command line.

When not to use it

Skip it if you have no Twilio account set up or if SMS is not the right communication channel.

Security analysis

Caution

Quality score85/100

The skill is legitimate and narrowly scoped to the `uni` CLI, with no destructive or exfiltration behavior. However, it handles Twilio credentials and can send real SMS messages, so it warrants caution rather than being treated as fully safe.

Findings

•Requires handling Twilio Account SID and Auth Token; the inline `uni twilio auth <ACCOUNT_SID> <AUTH_TOKEN>` form can expose secrets in shell history or process listings.
•Can send real SMS messages, which may incur charges or be abused if an agent is manipulated into messaging arbitrary numbers.
•Relies on an external `uni` CLI binary whose implementation is not audited here.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/twilio-sms-via-uni-cli-mma3jrpl/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/twilio-sms-via-uni-cli-mma3jrpl' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/twilio-sms-via-uni-cli-mma3jrpl/download' --output '.skill-downloads/twilio-sms-via-uni-cli-mma3jrpl/SKILL.md.part' && mv '.skill-downloads/twilio-sms-via-uni-cli-mma3jrpl/SKILL.md.part' '.skill-downloads/twilio-sms-via-uni-cli-mma3jrpl/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): Bash(uni:*), Bash(~/.local/bin/uni:*)

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/twilio-sms-via-uni-cli-mma3jrpl'

openskills read 'twilio-sms-via-uni-cli-mma3jrpl'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/twilio-sms-via-uni-cli-mma3jrpl/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
