Unit Converter

Comprehensive unit converter for length, weight, temperature, area, volume, speed, time, and data. Use when: (1) converting between measurement units, (2) ca...

Security Scan

The skill is an instruction-only unit converter with a local Python script that matches its description and does not request credentials or perform network actions.

Purpose & Capability

Name/description (unit conversion) aligns with the provided files and runtime instructions. The included Python script implements length, weight, temperature, area, volume, speed, time, and data conversions — consistent with the SKILL.md.

Instruction Scope

SKILL.md only instructs running the local Python script and listing/showing units. It does not direct reading unrelated system files, accessing environment variables, calling external endpoints, or collecting/transmitting user data. A minor note: SKILL.md mentions case-sensitivity for temperature and the script normalizes many inputs to lowercase but expects 'C','F','K' for temperature — users should follow the documented usage.

Install Mechanism

No install spec; the skill is instruction-only with a single local script. Nothing is downloaded or written to disk by an install process, so install-risk is minimal.

Credentials

The skill requires no environment variables, credentials, or config paths. The script operates purely on CLI args and internal tables, so requested privileges are proportional to its purpose.

Persistence & Privilege

always is false and model invocation is not disabled (default). The skill does not request persistent system changes or attempt to modify other skills or system settings.

Assessment

This skill appears coherent and low-risk: it runs a local Python converter script and does not use network, credentials, or external services. Before installing, you may (1) quickly scan the full script to confirm there are no hidden network/file operations (the provided snippet shows only conversion logic), (2) test common conversions in a sandbox or isolated environment, and (3) note small issues/typos in unit alias mappings (e.g., a malformed mapping for some 'fluid ounce' aliases in the provided snippet) — these are bugs, not security problems. If you expect strict unit name handling, verify the script's alias mapping and temperature case rules and fix locally if needed.

Convert between different measurement units. Supports length, weight, temperature, area, volume, speed, time, and data units.

When to Use

• Convert between metric and imperial units

Tips

• Use the list command to see all available units for a category
• Temperature units are case-sensitive (C, F, K)
• For compound units like m/s, use the slash notation
• The converter handles both short and long unit names
• Results are formatted for readability

Troubleshooting

"Cannot convert" error:

• Check unit spelling
• Ensure units are from the same category (e.g., don't convert length to weight)
• Use list command to see available units

Unexpected results:

• Temperature conversions use standard formulas
• Data conversions use 1024-based (binary) units
• Double-check unit case sensitivity

Notes

• Temperature conversions use standard formulas
• Data conversions use binary (1024-based) units
• All other conversions use decimal (1000-based) units
• Results are automatically formatted for readability
