Install a skill and finish one task

A checked paragraph and a factual change note.

You’ll need: Local Claude Code or Codex; the free ZIP. Python 3 is optional.

What you will make

A clear offer. With every condition intact.

You’ll use Draft Polish to repair an inaccurate paragraph, then save the copy and a short explanation of the changes. Everything you need for this fictional exercise is below.

The supplied draft

Transform your entire website for just €75 in 24 hours. Our pilot saves two hours every week. We do everything.

A worked result

Get recommendations for one homepage for €90 excluding VAT. Delivery is three working days after we receive your page link and brief. Implementation is not included. The pilot may save up to two hours of preparation per week.

01 / Get ready

Choose your coding assistant.

Use an authenticated local Claude Code or Codex environment that can open a project folder. Your own AI access is separate. The commands below are for macOS or Linux and use Python 3.

The installer puts the five skills in .agents/skills inside your practice project. You’ll call this one with $draft-polish.

Download the Free Starter

Five skills, four lessons and all example files · no email signup.

02 / Install

Give the exercise its own folder.

Unzip the download. In a terminal, open the extracted free-starter folder containing install.py and manifest.json. Run these two lines from that folder:

Ready to use
mkdir -p ../practical-dept-practice
python3 install.py install --host codex --project ../practical-dept-practice

This creates practical-dept-practice beside the extracted folder and installs the skills there. Look for install: 5 skills in the terminal. An existing installation or a name collision needs attention; use the update and troubleshooting guide instead of overwriting it.

Open that new practice folder in Codex and start a fresh session. Without Python, follow the guide’s manual folder-copy option. Windows command paths are not covered by this walkthrough.

03 / Run the skill

Give it the facts and the flawed draft.

Paste this complete task into your new session. Confirm the assistant loads Draft Polish. The two output files should appear inside your practice folder.

Ready to use
$draft-polish

This is a fictional practice exercise.

Authoritative offer: One homepage review, €90 excluding VAT; delivery three working days after receiving the page link and brief; recommendations only, no implementation. A pilot may save up to two hours of preparation per week; that is a possibility, not a measured result.

Draft: “Transform your entire website for just €75 in 24 hours. Our pilot saves two hours every week. We do everything.”

Polish the draft against the authoritative offer. Preserve every material condition. Save the edited copy to first-result.md and a short factual change note to change-note.md in this practice project. Do not publish or send the result.
04 / Check the result

Compare meaning, not identical wording.

Open first-result.md and compare it with the worked result above. Your version can read differently while preserving all the terms.

  • One homepage; recommendations only; implementation excluded.
  • €90 excluding VAT; three working days after the page link and brief arrive.
  • The pilot may save up to two hours of preparation per week.
If the wording is smooth but a fact changed

“Get your review in three days” drops both the working-day unit and the starting event. Ask for that exact repair, then reread the actual file. “Saves up to two hours” also needs “may.” Keep the failed sentence and your correction in the change note.

Then try a changed brief

In a fresh session, replace the terms with: two pages, €120 including VAT, five working days after final source files, no time-saving claim. Implementation is still excluded. Use the original task format and save a second result.

Worked answer: Get recommendations for two pages for €120 including VAT. Delivery is five working days after we receive the final source files. Implementation is not included.

Check that no old €90 price, one-page scope, three-day timing or saving remains.

Finish the Weekly Review exercise when you’re ready to try another skill. The next lesson shows how to keep source facts organized as a task grows.
