The Agent Skills Directory

[COMMAND_EXECUTION]: The skill relies on shell command execution to interface with the external codex CLI tool. It specifically uses complex commands involving process substitution ($(cat ...)), piping, and redirections (e.g., codex exec -s read-only --json -o /tmp/codex-verdict.txt ... < /dev/null).
[DATA_EXFILTRATION]: The skill instructs the agent to read the user's ~/.codex/config.toml file to determine the active model and echo it to the console. Accessing configuration files in the home directory is a sensitive operation, although here it is aligned with the skill's primary purpose of managing the Codex review process.
[INDIRECT_PROMPT_INJECTION]: The skill exhibits an attack surface for indirect prompt injection by reading output generated by a secondary model (Codex) from /tmp/codex-verdict.txt and appending it to a persistent log file (PLAN-REVIEW-LOG.md).
Ingestion points: /tmp/codex-verdict.txt (output of external CLI tool), PLAN.md, and local project documentation.
Boundary markers: The instructions specify an exact verdict line (VERDICT: APPROVED/REVISE), which serves as a weak delimiter, but does not include robust escaping for the critique text.
Capability inventory: Shell execution (codex exec), file reading (cat), and file writing/appending (PLAN.md, CONTEXT.md, PLAN-REVIEW-LOG.md).
Sanitization: No explicit sanitization or filtering of the external model's output is performed before it is added to the log or processed by the primary agent.
[DYNAMIC_EXECUTION]: The skill uses dynamic shell command construction, incorporating user-defined variables (like MAX_ROUNDS and PLAN_FILE) and reading contents of files directly into the command line via substitution ($(cat REVIEW_PROMPT)).
