Description

Convert spaces to tabs in text files. Use for consistent indentation and reducing file size by replacing spaces with tabs.

README (SKILL.md)

Unexpand - Space to Tab Converter

Replace sequences of spaces with tab characters. The inverse operation of expand-tool. Ideal for converting space-indented code to tab-indented format.

Usage

unexpand-tool [options] \x3Cfile>

Options

-t N: Set tab width in spaces (default: 8)
-a: Convert all spaces, not just leading
--first-only: Only convert leading sequences

Examples

unexpand-tool -t 4 file.py
unexpand-tool -a -t 2 data.txt
cat spaces.txt | unexpand-tool

Usage Guidance

This appears safe from a security perspective for simple local text conversion. Before installing, verify how the command is invoked, use it only on files you intend to read, and be aware that the documented options and stdin example are not correctly implemented by the included script.

Capability Analysis

Type: OpenClaw Skill Name: unexpand-tool Version: 1.0.0 The script scripts/unexpand.py contains a significant logic error and vulnerability where it attempts to use the entire content of stdin as a filename for open() if no command-line arguments are provided. Furthermore, the implementation is highly incomplete and does not support any of the flags (e.g., -t, -a) documented in SKILL.md, which could lead to unexpected behavior or unintended file access if an agent passes untrusted input through a pipe.

Capability Assessment

ℹ Purpose & Capability

The stated purpose is coherent and low-risk, but the included script only replaces exact 8-space sequences and does not implement the documented -t, -a, or --first-only options.

ℹ Instruction Scope

The SKILL.md shows piped-input usage, but the script treats stdin as a filename when no argument is provided, which could cause unexpected file reads or failures.

ℹ Install Mechanism

There is no install spec connecting the documented unexpand-tool command to the included Python script, so users should verify what command would actually run.

✓ Credentials

Reading a user-specified text file is proportionate for a spaces-to-tabs converter; no credentials, network access, or broad filesystem indexing are shown.

✓ Persistence & Privilege

The artifacts show no persistence, privilege escalation, background worker, destructive action, or account mutation.
