Tail Tool
PassAudited by ClawScan on May 4, 2026.
Overview
This is a simple local file-tail utility with no network, credentials, or persistence; users should only be aware that it can display local file contents and its documentation overstates some options.
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.

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
If the tool is used on a private log, key file, or other sensitive document, the last lines may be displayed in the chat or agent context.
The tool reads and prints local file or stdin contents supplied to it. This is expected for a tail utility, but it means sensitive files could be exposed to the agent context if selected.
lines = open(args.file).readlines() ... else: lines = sys.stdin.readlines()
Use it only on files you intend the agent to read, and confirm file paths before invoking it on sensitive systems.
The agent or user may expect real-time following or byte/quiet modes and instead get command errors or miss updates.
The documentation advertises options that are not present in the included script, which only implements a file argument and -n/--lines. This appears to be a capability mismatch rather than harmful behavior.
Includes follow-mode for watching files that grow in real-time. ... `-f`: Follow file growth ... `-c N`: Show last N bytes ... `-q`: Suppress filename headers
Verify supported options before relying on the skill for monitoring, or update the documentation/implementation so they match.
