Description
Simple text formatting and reflow tool. Use for reformatting paragraphs, removing extra whitespace, and cleaning up text files.
README (SKILL.md)
Fmt - Text Reformatting Utility
Reformat paragraphs of text to a specified width, removing extra whitespace and producing clean, consistently formatted output.
Usage
fmt-tool [options] [file...]
Options
-w N: Set output width (default: 75)-u: Uniform spacing (one space between words)-s: Split long lines only (don't join short ones)
Examples
fmt-tool -w 80 messy.txt
fmt-tool -u notes.txt
Usage Guidance
This package is small and not obviously malicious, but it is inconsistent: SKILL.md promises CLI flags, multi-file support, and a default width of 75, while scripts/fmt.py only implements a simple positional interface and defaults to width 80. Before installing or invoking it in automation: (1) review or run the script on a harmless test file to confirm behavior; (2) fix or request the author to implement proper CLI parsing (argparse) or update SKILL.md to match the actual interface; (3) avoid running it on sensitive files until you confirm it behaves as expected. If you need the documented features (-w, -u, -s, multiple files), prefer a version that implements them or patch the script yourself.
Capability Analysis
Type: OpenClaw Skill
Name: fmt-tool
Version: 1.0.0
The skill bundle provides a straightforward text formatting utility. The Python script `scripts/fmt.py` uses the standard `textwrap` library to reformat text from files or stdin, and the `SKILL.md` file contains standard documentation for the tool's usage without any signs of prompt injection or malicious instructions.
Capability Assessment
Purpose & Capability
The description (text reformatting/reflow) matches what scripts/fmt.py actually does: it reads a file or stdin and calls textwrap.fill. However the SKILL.md documents options (-w, -u, -s), multiple files, and a default width of 75 — none of which the script implements. The core capability is coherent, but the user-facing contract is inaccurate.
Instruction Scope
SKILL.md instructs use of flags (-w, -u, -s) and multiple file arguments. The script ignores flags and only accepts an optional single filename as argv[1] and a width as argv[2] (positional integer). This mismatch can produce unexpected behavior (e.g., users passing '-w 80 file' will break). The script also uses open(sys.argv[1]) which will read any path the user supplies — expected for a formatter but worth noting.
Install Mechanism
Instruction-only install: no install spec and no external downloads. The script is included in the bundle and is small and readable; no high-risk installers or remote fetches are present.
Credentials
The skill requests no environment variables, no credentials, and no config paths. The script performs only local file/stdin reads and text reflow — credentials or extra env access are not required.
Persistence & Privilege
The skill does not request always:true and has no special persistence or system-wide changes. It does not modify other skills or global agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install fmt-tool - After installation, invoke the skill by name or use
/fmt-tool - Provide required inputs per the skill's parameter spec and get structured output
