Gripper

Robot gripper reference — jaw types, force calculation, pneumatic vs electric, and end-effector selection. Use when designing gripping systems, selecting act...

Security Scan

The skill is a local, instruction-driven gripper reference that runs a bundled bash script to print guidance and calculations; its declared purpose matches the included files and there are no obvious requests for credentials, network calls, or installs in the visible code.

Purpose & Capability

Name/description (robot gripper reference) matches the runtime instructions and the included scripts which implement subcommands for types, force calculations, pneumatic/electric/vacuum guidance and checklists. There are no unrelated credentials, binaries, or install steps.

Instruction Scope

SKILL.md instructs the agent to run local commands (scripts/script.sh <command>) that produce reference text. The provided script functions only print documentation and formulas; there are no instructions to read unrelated system files, collect environment secrets, or send data externally in the visible portion.

Install Mechanism

No install spec — instruction-only usage with a bundled shell script. No downloads, package managers, or archive extraction are declared. The script is executed locally from the skill bundle.

Credentials

The skill declares an optional GRIPPER_DIR for local data storage but requires no environment variables or credentials. The script content shown does not access or exfiltrate secrets or external services.

Persistence & Privilege

always is false and the skill does not request persistent elevated privileges or modify other skill/system configs. It runs locally with normal agent invocation.

Assessment

This skill appears to be a self-contained reference implemented as a local bash script that prints engineering guidance and formulas. Before installing or executing: (1) review the entire scripts/script.sh (the provided content was truncated in the listing) to confirm there are no hidden network calls, file writes, or command substitutions later in the file; (2) run the script in a sandbox or isolated environment if you want to be extra cautious; (3) if you set GRIPPER_DIR, point it to a directory you control (it’s only for local data storage per the docs). If you see any curl/wget, base64, eval, or unexpected subprocess calls in the remainder of the script, treat it as suspicious and stop. Otherwise the skill is coherent with its stated purpose.

Gripper — Robot Gripper Reference

Quick-reference skill for gripper types, force calculations, actuator selection, and end-effector design.

When to Use

• Selecting a gripper type for a robot application
• Calculating required gripping force for a payload
• Choosing between pneumatic, electric, and vacuum grippers
• Designing custom jaw geometry for specific parts
• Troubleshooting grip failures in production
