The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes shell commands including codex, mix, and git to analyze code, run tests, and manage the local environment. These are standard operations for a developer tool.
[EXTERNAL_DOWNLOADS]: The skill references the installation of the Codex CLI tool via reputable sources such as Homebrew and NPM (@openai/codex). These are well-known and trusted services.
[DATA_EXPOSURE]: The skill stores intermediate review findings in the /tmp/ directory and references the standard configuration file ~/.codex/config.toml. It does not attempt to access sensitive credentials or exfiltrate private data.
[PROMPT_INJECTION]: The skill is designed to parse output from the Codex CLI to identify and apply fixes to code. This creates a surface for indirect prompt injection where manipulated tool output could influence the agent's behavior. However, the skill implements strict 'Iron Laws' and requires verification steps to mitigate risks. * Ingestion points: Findings are parsed from /tmp/codex-round-{n}.md generated by the external CLI tool. * Boundary markers: The agent looks for specific bullet point patterns (- [P(n)]) but lacks explicit delimiters to separate untrusted data from instructions. * Capability inventory: The skill can execute shell commands (mix, codex) and modify the local filesystem. * Sanitization: There is no explicit sanitization or filtering is applied to the text content extracted from the review findings before processing.
