The Agent Skills Directory

[COMMAND_EXECUTION]: The skill instructs the agent to execute an external CLI tool named codex with high-privilege configurations.
Evidence: The documentation explicitly suggests the use of the --sandbox danger-full-access flag, which allows the tool to bypass standard sandbox restrictions, granting network access and broad system permissions.
[COMMAND_EXECUTION]: Command patterns include 2>/dev/null by default to suppress the standard error stream.
Evidence: Suppressing stderr hides potentially critical security warnings, diagnostic errors, or 'thinking tokens' that would otherwise inform the user or agent of unexpected or malicious behavior during execution.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to process external code and user-provided prompts, creating an attack surface for indirect injection.
Ingestion points: Untrusted user prompts and workspace files are passed directly to the codex exec and codex resume commands in SKILL.md.
Boundary markers: No explicit boundary markers or instructions to ignore embedded commands are present in the provided templates.
Capability inventory: The tool has significant capabilities including file system write access (workspace-write) and full network access (danger-full-access).
Sanitization: There is no evidence of sanitization or validation logic to inspect the content being processed before execution.
