The Agent Skills Directory

[COMMAND_EXECUTION]: The skill in SKILL.md instructs the agent to construct and execute shell commands using dynamic placeholders, such as codex exec "Review the code in <file_name>...". This pattern is susceptible to command injection if the agent fails to sanitize filenames or other variables sourced from untrusted inputs before execution.
[INDIRECT_PROMPT_INJECTION]: The skill processes local code files to perform its review function, which represents a significant attack surface. Malicious code could contain instructions designed to manipulate the review output or trigger unintended agent actions during the subsequent 'fix' phase.
Ingestion points: Local source files read for review in SKILL.md (e.g., auth.py, email_validator.py).
Boundary markers: Absent; code content is passed directly to the review tool without delimiters.
Capability inventory: Shell command execution via codex exec and file modification via the Edit tool.
Sanitization: No sanitization or validation of the ingested code content is specified in the workflow.
[EXTERNAL_DOWNLOADS]: SKILL.md specifies a dependency on the Codex CLI binary. The instructions do not provide a verified source, version pinning, or integrity hashes for this executable, requiring the agent to rely on an unverified binary from the local environment.
