Cat Tool

Concatenate and display file contents to standard output.

Security Scan

The skill is a small, local 'cat' implementation that is internally consistent and requests no credentials or installs, but the documentation advertises features (-n, -s, '-' as stdin) that the included script does not implement.

Purpose & Capability

Name and description match the included script: it's a simple file-display tool. However, SKILL.md claims features (line numbers -n, squeeze blank lines -s, and treating '-' as stdin) that are not implemented by scripts/cat.py. The script only opens and prints files by name and prints a generic error on failure.

Instruction Scope

SKILL.md instructs the agent to read and concatenate files and shows examples using flags like -n; the runtime script only supports reading files named on the command line. The SKILL.md examples (e.g., 'cat-tool -n') are misleading because the script does not parse or implement those options. Aside from that mismatch, the instructions stay within the expected scope (reading files specified by the user).

Install Mechanism

No install spec and only a tiny Python script are provided. No external downloads or package installs are required, so risk from the install mechanism is low.

Credentials

The skill requests no environment variables, credentials, or config paths. The script performs only local file reads for paths passed as arguments, which aligns with its purpose.

Persistence & Privilege

The skill does not request persistent presence or elevated privileges (always is false). It does not modify other skills or system configuration.

Assessment

This skill appears to be what it says: a tiny local 'cat' script that reads files you pass to it and prints them to stdout, and it doesn't request credentials or install anything. However, SKILL.md advertises features (line numbering, squeezing blank lines, '-' for stdin) that are not implemented in scripts/cat.py — treat the documentation as inaccurate. The script also uses a bare except (which hides error details) and will attempt to open a file literally named '-' rather than reading stdin. Before installing or allowing an agent to use it, consider: (1) review or fix the script to implement advertised flags and proper stdin handling, (2) replace the bare except with specific error handling to surface useful messages, and (3) avoid passing sensitive file paths to the skill since it will read any file path you provide. If you need those improvements but cannot modify the skill, do not rely on the advertised flags or stdin behavior.
