Security audit
Security checks for vulnerabilities and agentic risk
This skill is a disclosed local Rust tool for displaying guitar chord diagrams, with only minor local build and optional file-output side effects.
Install this only if you are comfortable running a bundled Rust CLI and allowing Cargo to create build artifacts in the skill directory. Avoid using all --save unless you want it to write or overwrite all_supported_chords.md in the current working directory.
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
This will:
1. Create a `.gitignore` in the skill directory to exclude cargo build artifacts (`/target`) from git
2. Pre-warm the cargo build cache so the first chord lookup is fast
## First Run Warning
The skill description says it shows ASCII guitar chord diagrams, but the CLI also supports writing a Markdown file to disk via the All --save path. That is a capability expansion beyond simple display behavior, which matters in agent settings because file-system side effects can be triggered unexpectedly and used to persist data or alter the workspace.
The --save option performs a local file write to ./all_supported_chords.md without that capability being justified by the stated purpose of merely showing chord diagrams. In an agent environment, unjustified write primitives increase risk because they can create or overwrite files in the current working directory, introducing persistence and unintended state changes.
The code writes output to disk when --save is used, but there is no explicit warning, confirmation, or prominent disclosure to users about the filesystem side effect. While the written content is non-sensitive chord data, undisclosed file writes are still risky in agent workflows because they can surprise users and leave artifacts in the workspace.
No suspicious patterns detected.
