ABOUTCODEX / COMPARE SKILLS
Compare Codex skills
Compare requirements, permissions, expected outputs, and recorded evaluation evidence for up to three Codex skills.
| Compare | Turn a request into a project brief |
|---|---|
| Best for | Define the outcome, constraints, and evidence for a focused change before implementation begins. |
| Requirements | A task description and access to the relevant project context. Repository access helps confirm constraints; no external account or executable script is required. |
| Permissions | Access needed: A task description and access to the relevant project context. Repository access helps confirm constraints; no external account or executable script is required. The instruction package grants no permissions by itself; use only the access and actions authorized for your task. |
| Expected output | A focused brief whose acceptance criteria can be demonstrated, with assumptions clearly separated from confirmed facts. |
| Review status | Workflow evaluated |
| Last checked | 2026-09-10 |
| Evaluation environment | Assistant-led text review; local Python 3.14.5 checklist runner. |
| Evidence | Manually applied the published skill to one book-club documentation request. The resulting brief passed six checklist assertions for outcome, scope, unknowns, dependencies, acceptance, and review gate. No independent evaluator or automatic invocation benchmark. Full report: https://aboutcodex.com/project-brief-skill-evaluation/ Scope is limited to the recorded exercise. |
| Limitations | This skill scopes a change; it does not establish budget estimates or prove that the implementation passes its checks. |
| Version | 1.0.0 |

Structure checks validate the package, not its performance. “Not documented” means the author has not supplied that information.
