Full Analysis
  • [EXTERNAL_DOWNLOADS]: The skill references and requires the OpenAI codex CLI tool as a prerequisite for its implementation workflow.
  • [COMMAND_EXECUTION]: Executes shell commands including codex exec with workspace write permissions, git status, and user-defined verification scripts to modify and validate code.
  • [PROMPT_INJECTION]: Identified an indirect prompt injection surface (Category 8) due to the nature of automated code modification based on potentially untrusted repository data.
  • Ingestion points: Repository files and user-defined implementation goals are ingested into the context via the codex tool in SKILL.md.
  • Boundary markers: The skill recommends writing self-contained prompts but does not specify technical delimiters to isolate instructions from the repository content processed by the tool.
  • Capability inventory: The skill possesses the capability to write to the file system (workspace-write) and execute arbitrary verification commands (tests, typechecks) on the resulting output.
  • Sanitization: Mitigation is implemented via instructions to manually inspect git diffs and run specific verification commands before finalizing changes.
