在 OpenClaw 中安装
/install tac-tool
功能描述
Concatenate and display files in reverse line order (last line first). Use for viewing log files from newest entries and reversing file content.
使用说明 (SKILL.md)
Tac - Reverse File Concatenation
Display file contents with lines in reverse order. The last line appears first, making it useful for viewing recent log entries and processing data in reverse.
Usage
tac-tool [options] \x3Cfile...>
Examples
tac-tool log.txt
tac-tool file1.txt file2.txt > reversed_combined.txt
安全使用建议
This appears safe for its stated purpose. Only use it on files you are comfortable letting the agent read and display; also note that the included script appears to handle only one filename despite the documentation showing multiple-file usage.
功能分析
Type: OpenClaw Skill
Name: tac-tool
Version: 1.0.0
The skill provides a simple utility to reverse the lines of a file, mimicking the Unix 'tac' command. While the implementation in 'scripts/tac.py' contains a logic error in its handling of standard input (attempting to open the content of stdin as a filename), the code and documentation in 'SKILL.md' show no signs of malicious intent, data exfiltration, or prompt injection.
能力评估
Purpose & Capability
The stated purpose is to display file contents in reverse line order, and the included script reads a supplied file and prints its lines reversed. There is a minor non-security mismatch: the documentation suggests multiple files/options, while the script only uses the first argument.
Instruction Scope
The SKILL.md provides simple user-invoked command examples and does not instruct the agent to override user intent, run automatically, or perform unrelated actions.
Install Mechanism
There is no install spec, no declared external dependencies, and only one small local Python script is included.
Credentials
Local file reading is necessary for this tool's purpose, and the artifacts show no environment variable access, credential use, network calls, or system modification.
Persistence & Privilege
The artifacts show no persistence, background execution, privilege escalation, or long-running behavior.
如何使用
