How to use the Finalize Agent Prompt agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The finalize-agent-prompt skill is a set of instructions for Claude that makes it act as an experienced AI agent reviewing a prompt file. It polishes the file for the end user: tightening structure and wording, fixing spelling, grammar and clarity problems, and keeping the front matter and markdown formatting intact. This guide is for developers and teams writing custom agent or prompt files, and it shows you how to install the skill, trigger it and get useful results.

What does the finalize-agent-prompt skill do?
The skill takes an existing prompt file, meaning a text file of instructions meant for an AI, and refines it. The source describes the agent reading the file carefully, refining its structure, wording and organisation, and then checking for spelling, grammar or clarity issues.
The skill is designed to correct these problems without changing the original intent of the instructions. It keeps the prompt's front matter, encoding and markdown structure while making improvements. If you do not supply a prompt file, the agent asks you for one before proceeding.
- Tightens structure and wording of the prompt
- Fixes spelling, grammar and clarity problems
- Keeps front matter and markdown formatting intact
- Asks for the prompt file if none is provided
What is an agent skill and how do you install this one?
An agent skill is a folder of instructions, centred on a SKILL.md file, that an AI agent can load when a task matches it. This skill's only listed file is SKILL.md. It has no required software and runs no scripts.
To install it, download the ZIP from the item page on this site and unzip it into one of these locations: ~/.claude/skills/ for personal use, or a project's .claude/skills/ folder to share it within a project. Alternatively, upload it in the Claude apps under Settings → Capabilities → Skills.
- Personal install: unzip into ~/.claude/skills/
- Project install: unzip into the project's .claude/skills/ folder
- Claude apps: Settings → Capabilities → Skills, then upload the skill
How do you trigger the skill with a natural request?
You do not need a special command. Give the agent your prompt file and ask in plain language for it to be polished, proofread or tidied up. The skill's description covers finalizing a prompt file to polish it for the end user, so requests that match that purpose are the ones it is built for.
If you paste or name a prompt file, the agent will work from that file. If you ask for a polish without providing one, expect the agent to ask you for the file first.
- "Finalize this agent prompt file for the end user."
- "Proofread my prompt file and fix any grammar or clarity problems."
- "Tidy the structure of this prompt, but keep the front matter as it is."
What should you check in the result?
The skill aims to keep the original intent, but you are the one who knows what the prompt must do. Compare the polished version with your original, confirm the front matter and markdown still look right, and make sure no instruction has changed meaning.
The skill relies on the model's general sense of best practice. It has no test harness or evaluation, so it does not verify that the revised prompt performs better.
- Check that the meaning of each instruction is unchanged
- Confirm the front matter and markdown formatting are intact
- Test the revised prompt yourself if its results matter
What are the limits and safety notes?
The skill runs no scripts and uses no network access, according to its listing. It has no listed requirements.
Do not rely on it for tasks that need the prompt's behaviour changed or new features added, because it is limited to polishing without altering intent. Also avoid relying on it alone for prompts with legal, medical or safety-critical instructions; those need expert review before use.
- No scripts are run and no network use is listed
- Not suitable for changing behaviour or adding features
- Not a substitute for expert review of legal, medical or safety-critical prompts
What people use it for
- Cleaning up a custom agent file before sharing it with colleagues
- Standardising the wording and layout of several prompt files in a team
- Proofreading a prompt for spelling and grammar before publishing it
- Restructuring a long set of instructions so each section is easier to follow
Frequently asked questions
Is the finalize-agent-prompt skill free?
The skill is published under the MIT licence on the github/awesome-copilot repository. The source does not list any price, so check the item page for current details.
What do I need to use finalize-agent-prompt?
The listing shows no requirements, does not run scripts and does not use the network. You need a way to load agent skills, such as the Claude apps or Claude Code with a skills folder.
How do I install the finalize-agent-prompt skill?
Download the ZIP from this site and unzip it into ~/.claude/skills/ or a project's .claude/skills/ folder. You can also upload it in the Claude apps under Settings → Capabilities → Skills.
Will the skill change what my prompt does?
It is designed not to. The skill polishes structure, wording, spelling and grammar without changing the original intent, and it keeps front matter and markdown intact. You should still check the result against your original.
What happens if I don't give the skill a prompt file?
The agent asks you for the prompt file before it continues. Provide the file in your request to avoid this step.
How does this compare to a general proofreading tool?
A spelling checker only fixes words. This skill also reviews structure and organisation of an AI prompt, but it relies on general best-practice judgement and does not test the prompt's results.

Our verdict
Use finalize-agent-prompt if you write custom agent or prompt files and want a clean, consistently structured final version without changing what they do. Pick something else if you need the prompt's behaviour changed, need results verified by testing, or are working with legal, medical or safety-critical instructions that need expert review.
