Description
Translate or delete characters from input streams. Use for character substitution, deletion, and squeezing repeated characters.
README (SKILL.md)
Tr - Character Translation Utility
Translate, squeeze, or delete characters from standard input. Replaces specified characters with alternatives or removes them entirely.
Usage
tr-tool [options] \x3Cset1> [set2]
Common Uses
'a-z' 'A-Z': Convert lowercase to uppercase'\ ' ' ': Replace newlines with spaces-d 'aeiou': Delete all vowels-s ' ': Squeeze repeated spaces
Examples
echo "hello" | tr-tool 'a-z' 'A-Z'
echo "foo bar" | tr-tool -d ' '
echo "hello world" | tr-tool -s ' '
Usage Guidance
This skill appears safe for simple local character substitution, but do not rely on the documented delete or squeeze options unless you verify they are implemented.
Capability Analysis
Type: OpenClaw Skill
Name: tr-tool
Version: 1.0.0
The tr-tool skill is a straightforward implementation of a character translation utility, similar to the Unix 'tr' command. The core logic in scripts/tr.py uses standard Python string translation methods (str.maketrans) to process input from stdin, and the SKILL.md documentation accurately reflects this functionality without any suspicious instructions or prompt injection attempts.
Capability Assessment
Purpose & Capability
The stated purpose is character translation/deletion/squeezing, but the included script only implements a basic two-argument character translation flow and does not handle the documented -d or -s options.
Instruction Scope
The instructions are limited to user-directed command examples using standard input; they do not attempt to override user intent or require autonomous high-impact actions.
Install Mechanism
There is no install spec, no dependencies, and no required binaries or environment variables. The included Python file is small and local.
Credentials
The artifacts show only stdin-to-stdout text transformation. There is no evidence of filesystem scanning, network access, credential use, or configuration access.
Persistence & Privilege
No persistence, background execution, privilege escalation, account access, or stored state is shown.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install tr-tool - After installation, invoke the skill by name or use
/tr-tool - Provide required inputs per the skill's parameter spec and get structured output
