Can I see a preview of the commands before they are executed?

Yes. Every invocation generates a clear Execution Plan that categorizes commands with status indicators, showing you exactly what will run, what requires confirmation, and what will be skipped.

How does Command Executor ensure my system stays safe?

The skill utilizes a strict safety policy that blocks dangerous commands like 'rm -rf' or 'drop database' and requires explicit user confirmation for any operation that modifies files or installs dependencies.

Where are the execution logs and audit trails stored?

All execution data, including output captures and timestamps, are stored locally in the '.cache/command-validations/' directory for easy auditing and offline access.

Does this skill work with non-JavaScript projects?

While it includes specific optimizations for Node.js workflows, it is a cross-platform tool capable of discovering and executing any standard shell commands found in your project's markdown documentation.

How does the performance regression detection work?

The skill saves execution times to a local cache and compares the current run's duration against previous benchmarks. If a command takes more than 1.5x its usual time, it flags it as a potential regression.

セキュリティとテスト

Executes and validates terminal commands safely while capturing real output and monitoring for performance regressions.

概要

Command Executor is a specialized Claude Code skill designed to bridge the gap between identifying shell commands and running them with confidence. It implements a robust safety layer by categorizing commands into safe, conditional, or dangerous groups, effectively preventing accidental data loss or destructive operations. The skill automates the execution of build scripts, tests, and linters while capturing granular metrics—including stdout, stderr, exit codes, and duration—into a persistent local cache. By integrating with git-aware change detection, it ensures that your project documentation remains accurate and your scripts remain performant across different environments.
