What it does
useful-codex-skills is a small collection of Codex skills that builds a chain from idea to execution. The `grill-me` skill pressure-tests a plan or design through a decision-tree interview. `grillcraft` turns the grilling results into a `decision.md` file, an improved ExecPlan and an execution goal. Next, `execplan-create` formats a decided refactor or PRD as an ExecPlan inside a work-item directory, `execplan-improve` rereads the plan against the code and rewrites it more concretely, and `implement-execplan` runs the plan while tracking state explicitly. Separately, `goalcraft` prepares an evidence-checked objective for `/goal`, and `reorient-myself` audits a task from first principles and returns one prompt to get back on track.
Who it is for. Codex users who run large tasks through plans and goals and want planning discipline captured as repeatable skills.
Good fit when
- A refactor plan is interrogated first and then turned into an ExecPlan.
- A vague wish becomes a `/goal` objective with checkable conditions.
- A Codex task drifted off course and needs a prompt to return to the goal.
- An existing ExecPlan must be tied to real paths in the code.
Not a fit when
- Work runs in Claude Code or Cursor while the skills target Codex.
- The task is small and plan interrogation takes longer than the implementation.
- You need skills that read other services through connections.
Example request
Run my migration plan through grill-me, then finish with grillcraft: decision.md, an improved ExecPlan and a /goal objective.Limitations
The skills are written for Codex and load from `~/.codex/skills`. The README also lists `review-recent-work` and `explain-code-change`, but the repository tree has no folders for them, so count on seven skills. By description `explain-code-change` needs an authenticated Notion connection. The `publish.sh` script symlinks repository folders so edits show up in Codex immediately and copies never drift. The license is MIT, and content grows without version numbers.
How to disable. Remove the symlinks or simply delete the needed folders in `~/.codex/skills`. The repository itself stays untouched.
FAQ
In what order do I run the skills?
Usually `grill-me`, then `grillcraft`, then a manual review after implementation. The lower level, `execplan-create`, `execplan-improve` and `implement-execplan`, can be called directly for a manual chain.
How do I wire in all skills?
Clone the repository and run `./publish.sh --link-all`. `./publish.sh --status` shows which skills are already symlinked.
What is Goalcraft?
A skill that turns a rough draft or vague ambition into a compact, evidence-checked objective for Codex `/goal`. The folder includes `validate_goal_length.py` to check length.
What is reorient-myself for?
The skill audits a Codex task from first principles and returns one ready prompt that puts the work back on track.
Are outside connections needed?
Not for the main seven skills. Only the one that publishes explanations to Notion needs a connected and authenticated integration, if it is added to the repository.
