The Agent Skills Directory

[SAFE]: The skill functions as a code generator for local environment hooks. It creates shell scripts in the .codex directory and sets execution permissions via chmod 755 to allow the platform to run them.
[OBFUSCATION]: The Python scaffolding script uses string concatenation (e.g., ig""nore) to define security-sensitive keywords within its defensive blocklist templates. This is a non-malicious use of obfuscation designed to prevent safety filters from interfering with the generation of security rules.
[PROMPT_INJECTION]: The skill generates scripts specifically designed to detect and mitigate prompt injection attempts by monitoring user input for bypass keywords and instructing the agent to maintain its system prompt.
