Use when calculating CNC speeds and feeds, selecting cutting tools, referencing G-code commands, looking up material cutting data, or computing machining par...

Security Scan

The skill's files and runtime instructions are coherent with a CNC/CAM reference tool — it runs a local bash script (which invokes python3) to produce speeds/feeds, G-code references, material data, and simple calculations and does not request credentials or reach out to external endpoints.

Purpose & Capability

The name/description match the included behavior: the script provides speeds & feeds, toolpath guidance, G-/M-code references, material data, and simple machining calculations. One minor mismatch: the registry metadata declares no required binaries, but the script invokes bash and python3 (so a runtime with python3 is necessary). This is an implementation detail rather than malicious.

Instruction Scope

SKILL.md instructs the agent to run the bundled scripts/script.sh with specific subcommands and arguments. The script's behavior is limited to printing references and performing local arithmetic via embedded Python; it does not read arbitrary user files, access secrets, or transmit data to external endpoints.

Install Mechanism

There is no install spec and no downloads — the skill is instruction-only with a bundled script. No remote install URLs, archives, or third-party package pulls are present in the repository files provided.

Credentials

The skill declares no required environment variables or credentials and does not attempt to access secrets. It uses temporary environment variables as a mechanism for passing parameters into inline Python, which is proportional to its calculation tasks.

Persistence & Privilege

The skill is not set to always:true, does not request persistent system privileges, and does not modify other skills or system configuration according to the provided files.

Assessment

This skill appears to be what it claims: a local CNC/CAM reference and calculator implemented as a bash script that calls python3. Before installing or running it: 1) ensure your runtime supports bash and python3 (the metadata omitted python3 as a required binary); 2) review the bundled scripts (you already have them) if you want to verify there are no additional commands added; 3) note the script prints a website link but does not perform network calls or request credentials. If you don't trust the author or want stricter isolation, run the script in a restricted environment (container or VM) before giving it broader access.
