Usage
tail-tool [options] [file...]
Options
-n N: Show last N lines-f: Follow file growth (watch mode)-c N: Show last N bytes-q: Suppress filename headers
Examples
# Show last 10 lines
tail-tool log.txt
# Show last 50 lines
tail-tool -n 50 access.log
# Follow log in real-time
tail-tool -f /var/log/syslog
Usage Guidance
This skill appears safe for ordinary log or text-file viewing. Before installing or using it, remember that any file you ask it to read may be shown to the agent, and do not rely on the advertised follow, byte, quiet, or multiple-file options unless the implementation is updated to support them.
Capability Analysis
Type: OpenClaw Skill
Name: tail-tool
Version: 1.0.0
The skill bundle provides a standard implementation of a file tailing utility. The Python script `scripts/tail.py` and the documentation in `SKILL.md` are consistent with the stated purpose of displaying the last lines of a file. No indicators of malicious intent, data exfiltration, or prompt injection were found.
Capability Assessment
Purpose & Capability
The stated purpose of showing the last lines of files matches the included script, but SKILL.md advertises follow mode, byte mode, quiet mode, and multiple-file style usage that the script does not implement.
Instruction Scope
The skill is scoped to user-directed file viewing. Because it accepts arbitrary file paths or stdin, users should avoid pointing it at secrets or private files unless they intend those contents to enter the agent conversation.
Install Mechanism
There is no install spec, dependency installation, remote download, or install-time execution shown. The included Python script is small and self-contained.
Credentials
Reading local files is expected and proportionate for a tail-style tool. No evidence shows network access, credential handling, file writes, or unrelated system access.
Persistence & Privilege
No persistence, background service, privilege escalation, credential use, or ongoing autonomous behavior is shown. The advertised follow mode is not implemented in the included script.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install tail-tool - After installation, invoke the skill by name or use
/tail-tool - Provide required inputs per the skill's parameter spec and get structured output
