What this skill does
# Twilio SMS Skill - Text Message Bridge for Claude Code
Send and receive SMS/MMS messages through Twilio, with auto-response via Claude Code.
## Setup
### 1. Get Twilio Credentials
1. Sign up at https://www.twilio.com/
2. Get a phone number (or use trial number)
3. Find your Account SID and Auth Token in the console
### 2. Configure the Skill
Create `config.json`:
```json
{
"account_sid": "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"auth_token": "your_auth_token_here",
"phone_number": "+1234567890",
"allowed_numbers": ["+1987654321"]
}
```
- `account_sid`: Your Twilio Account SID
- `auth_token`: Your Twilio Auth Token
- `phone_number`: Your Twilio phone number (the one that sends/receives)
- `allowed_numbers`: List of phone numbers allowed to interact (for security)
### 3. Install Dependencies
```bash
pip install twilio flask
```
### 4. Set Up Webhook (for receiving messages)
The bridge needs a public URL for Twilio webhooks. Options:
**Option A: ngrok (for local development)**
```bash
# Terminal 1: Start the bridge
python ~/.claude/skills/twilio-sms/twilio_bridge.py --auto
# Terminal 2: Expose with ngrok
ngrok http 5001
```
Then set the ngrok URL in Twilio Console -> Phone Numbers -> Your Number -> Messaging -> Webhook URL: `https://xxxx.ngrok.io/sms`
**Option B: Deploy to server**
Deploy twilio_bridge.py to a server with a public URL.
## CLI Usage
```bash
# Send an SMS
python twilio_skill.py send +1234567890 -m "Hello from Claude!"
# Send MMS (with image URL)
python twilio_skill.py send +1234567890 -m "Check this out" --media https://example.com/image.png
# Read recent inbox
python twilio_skill.py inbox
# Check conversation history with a number
python twilio_skill.py history +1234567890
# Check Twilio account status
python twilio_skill.py status
```
## Bridge Mode (Auto-Response)
```bash
# Start the bridge with auto-respond
python twilio_bridge.py --auto --workdir /path/to/workspace
# Start in background
python twilio_bridge.py --auto --daemon
# Check status
python twilio_bridge.py --status
# Stop
python twilio_bridge.py --stop
# View inbox
python twilio_bridge.py --inbox
```
## Features
- **Auto-response**: Incoming SMS triggers Claude Code, response sent back
- **Conversation tracking**: Maintains context across messages from same number
- **Progress updates**: Sends "Working on it..." for long-running tasks
- **MMS support**: Can send images (requires public URL)
- **Security**: Only responds to allowed phone numbers
## Required Twilio Permissions
- Send SMS/MMS
- Receive SMS/MMS (webhook)
- Phone number with SMS capability
## Files
- `twilio_skill.py` - CLI for sending messages
- `twilio_bridge.py` - Webhook server for auto-response
- `config.json` - Twilio credentials (create this)
- `inbox.jsonl` - Received messages log

skill-development
IncludedComprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.
reprompter
IncludedTransform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.
adaptive-compaction
IncludedAdaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.
agent-skill-creator
IncludedCreate cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.
llm-wiki
IncludedUse when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.
skill-master
IncludedAgent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
