Security Scan

The skill's files match its stated purpose, but the included Python script computes a data directory path that likely escapes the skill folder (a bug/incoherence that could cause it to read unexpected JSON files); review or fix before installing.

Purpose & Capability

Name, description, SKILL.md and reference docs align with a bearing search/lookup skill. Included reference docs and example data formats are appropriate for the claimed functionality and no unrelated credentials or binaries are requested.

Instruction Scope

SKILL.md says data is stored under data/models and data/brands within the project, but scripts/search_model.py's get_data_dir() computes project_dir = skill_dir.parent.parent.parent which (unlike the documentation) climbs multiple levels above the skill directory. This mismatch can cause the script to search for a data/ directory outside the skill (unexpected filesystem access). The script otherwise only reads local JSON files and prints results (no network or env-var exfiltration), but the path bug broadens the files it may open.

Install Mechanism

No install spec (instruction-only plus a small script). No packages downloaded or archives extracted; risk from installation mechanism is low.

Credentials

The skill declares no required environment variables, and the code does not read environment variables or credentials. Requested permissions are proportional to the stated purpose.

Persistence & Privilege

always is false and the skill does not modify other skills or system settings. It has no elevated persistence or special privileges.

What to consider before installing

This skill appears to implement a legitimate bearing lookup, but review the included script before use. The search_model.py's get_data_dir() climbs three directory levels above the skill, which contradicts the SKILL.md and may cause the script to read JSON files outside the project. Actions to consider before installing or running: (1) Inspect and run the script in a sandboxed environment. (2) Verify there is no sensitive data in any parent-level data/ directories that the script could read. (3) Fix the path calculation (use the repository root or the skill folder explicitly; e.g., set project_dir = script_dir.parent or project_dir = Path(__file__).resolve().parent.parent if data is next to the repo root). (4) If you can't change the code, run the skill with limited filesystem permissions or in a container. There are no network calls or credential requests in the code, so the main concern is unintended local file access rather than exfiltration. If you want, provide a copy of the data/ directory layout you plan to use and I can suggest an explicit safe path change.
