| description | A skill for reliably creating files using shell commands |
Reliably create files via shell commands, avoiding quoting/escaping/redirection pitfalls.
Use this when a tool's
createorwriteprimitive isn't available, or when content has special characters that break redirection.
Method 1: tee (recommended — handles special chars, quotes, newlines)
process:
command: "tee"
args: ["/path/to/file.txt"]
stdin: "file content here"
Method 2: here-doc (alternative for multiline content)
process:
command: "sh"
args: ["-c", "cat > /path/to/file.txt << 'EOF'\ncontent here\nEOF"]
Method 3: printf (for escape sequences / precise formatting)
process:
command: "sh"
args: ["-c", "printf '%s' '$CONTENT' > /path/to/file.txt"]
Create parent dirs first with -p:
process:
command: "mkdir"
args: ["-p", "/parent/dir"]
# 1. Create directory
process:
command: "mkdir"
args: ["-p", "~/.agents/skills/my-skill"]
# 2. Write file
process:
command: "tee"
args: ["~/.agents/skills/my-skill/SKILL.md"]
stdin: "# my-skill\n\n## Usage\n..."
# 3. Verify
process:
command: "ls"
args: ["-la", "~/.agents/skills/my-skill/"]
