Permissions System With Sandbox Security And Capability Isolation

via “safe path validation and dangerous command blocking”

Bash is all you need - A nano claude code–like 「agent harness」, built from 0 to 1

Unique: Combines filesystem-level path whitelisting with command-pattern blacklisting, creating a two-layer defense that is simple to understand and audit. Most frameworks either omit this entirely or use complex capability-based security models.

vs others: Simpler and more transparent than capability-based security (like secomp or AppArmor) because rules are human-readable and can be inspected without kernel knowledge, making it suitable for educational and small-scale deployments.
