92%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A lean, well-structured instruction skill with concrete commands, explicit flag policy, and genuine validation checkpoints (availability, auth, error-event/nonzero-exit handling). The only improvement opportunity is showing one complete example invocation that combines the base command with the sandbox flags.
Suggestions
Add one fully assembled example command for the common case, e.g., `codex exec "Review this diff and report issues" --sandbox read-only --json`, replacing or supplementing the prose "Example: for a review request" paragraph.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~27-line body contains no padding and no explanations of concepts Claude already knows — e.g., "Pass the prompt as one quoted argument. Parse stdout as JSONL, preserve event order" and "Never request, read, print, or copy credentials" are pure instruction. Every token earns its place, matching the lean-and-efficient anchor. | 5 / 5 |
Actionability | Concrete executable guidance is present throughout: `command -v codex`, `codex exec "<prompt>" --json`, and flag-level direction (`--sandbox read-only`, `--skip-git-repo-check`, never `--dangerously-bypass-approvals-and-sandbox`). The minor gap is that no complete example invocation combining the flags is shown — the "Example: for a review request" paragraph is prose rather than a runnable command — so it sits at mostly-executable rather than copy-paste-ready. | 4 / 5 |
Workflow Clarity | A clear 3-step sequence with explicit checkpoints and recovery paths: availability check ("Check availability with `command -v codex`. If it is missing, stop and ask"), auth handling ("If Codex reports missing login or API configuration, stop and ask"), and failure detection ("Treat an error event or nonzero exit as failure"). This is a single-task, non-destructive skill, so the validation-cap rule does not apply and the unambiguous single workflow matches the top anchor. | 5 / 5 |
Progressive Disclosure | The skill is under 50 lines with no need for external references, and the body is cleanly organized into two well-labeled sections ("## Run", "## Authentication And Permissions") with no inlined content that belongs in separate files. Per the under-50-lines guideline, this warrants the top score; the body references no files and no bundle files exist. | 5 / 5 |
