Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
4 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by aiskillstore on GitHub. Read the source before you install it.

Installation

Install the Claude Code Headless AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/aiskillstore/marketplace.git /tmp/marketplace
mkdir -p .claude/skills
cp -r /tmp/marketplace/skills/0xdarkmatter/claude-code-headless .claude/skills/claude-code-headless

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Claude Code Headless in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Claude Code Headless on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Claude Code Headless is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Claude Code Headless Mode

Run Claude Code from scripts without interactive UI.

Quick Start

bash
# Basic headless execution
claude -p "Explain this code" --allowedTools "Read,Grep"

# JSON output for parsing
claude -p "List files" --output-format json

# Continue conversation
claude -p "Start analysis" --output-format json > result.json
session=$(jq -r '.session_id' result.json)
claude --resume "$session" "Now fix the issues"

Essential CLI Options

Flag	Description
`-p`, `--print`	Non-interactive (headless) mode
`--output-format`	text, json, stream-json
`-r`, `--resume`	Resume by session ID
`-c`, `--continue`	Continue most recent session
`--allowedTools`	Comma-separated allowed tools
`--disallowedTools`	Comma-separated denied tools
`--mcp-config`	Path to MCP server config JSON
`--verbose`	Enable verbose logging
`--append-system-prompt`	Add to system prompt

Permission Modes

Mode	Flag	Effect
Default	(none)	Prompt for permissions
Accept edits	`--permission-mode acceptEdits`	Auto-accept file changes
Bypass	`--permission-mode bypassPermissions`	Skip all prompts

Output Formats

Text (default)

bash
claude -p "Hello"
# Outputs: Human-readable response

JSON

bash
claude -p "Hello" --output-format json

json
{
  "type": "result",
  "subtype": "success",
  "result": "Hello! How can I help?",
  "session_id": "abc123",
  "total_cost_usd": 0.001,
  "duration_ms": 1234,
  "num_turns": 1
}

Stream-JSON

bash
claude -p "Hello" --output-format stream-json
# Real-time JSONL output for each message

Common Patterns

Script with tool restrictions

bash
claude -p "Analyze the codebase" \
  --allowedTools "Read,Grep,Glob" \
  --disallowedTools "Write,Edit,Bash"

CI/CD integration

bash
claude -p "Review this PR diff" \
  --permission-mode acceptEdits \
  --output-format json \
  --append-system-prompt "Focus on security issues"

Multi-turn automation

bash
session=$(claude -p "Start task" --output-format json | jq -r '.session_id')
claude --resume "$session" "Continue with step 2"
claude --resume "$session" "Finalize and report"

Error Handling

bash
result=$(claude -p "Task" --output-format json)
if [[ $(echo "$result" | jq -r '.is_error') == "true" ]]; then
    echo "Error: $(echo "$result" | jq -r '.result')" >&2
    exit 1
fi

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Claude Code Headless AI skill do?

Run Claude Code programmatically without interactive UI. Triggers on: headless, CLI automation, --print, output-format, stream-json, CI/CD, scripting.

Why use Claude Code Headless on TypingMind?

Because you install it once and use it with any model. Claude Code Headless is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Claude Code Headless in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/aiskillstore/marketplace/tree/main/skills/0xdarkmatter/claude-code-headless. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Claude Code Headless?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Claude Code Headless?

As many as you like. As long as a model supports skills, you can use Claude Code Headless with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Claude Code Headless AI skill free?

It is published on GitHub by aiskillstore. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
