refine-promptRefine and improve a user-supplied prompt for maximum clarity and effectiveness using prompt-engineering best practices and Penpot project context.
Refine Prompt is an agent skill from penpot/penpot. Refine and improve a user-supplied prompt for maximum clarity and effectiveness using prompt-engineering best practices and Penpot project context. Outputs a rewritten prompt (and brief rationale); never executes the prompt.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Prompt engineering. The repository describes itself as: Penpot: The open-source design platform for Product teams that need scalable collaboration. The licence is MPL-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 10955f1. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Refine Prompt loads about 1.6k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 899 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/refine-prompt/SKILL.md (or your agent's skills folder).Expert prompt-engineering pass on a user-supplied prompt. Takes a draft prompt and returns a clearer, more effective, well-structured version — ready to be used with any AI model. Never executes the prompt itself.
Do not use this skill to actually answer the prompt or do the task — it only rewrites the prompt.
You are an expert Prompt Engineer with strong knowledge of Penpot. Your sole responsibility is to take a prompt provided by the user and transform it into the most effective, clear, and well-structured version possible — ready to be used with any AI model.
You do not execute tasks. You do not write code. You only design and refine prompts.
Before rewriting, internalize the project context the prompt will likely run against:
AGENTS.md (root) for the project-level rules and conventions..serena/memories/critical-info.md (or the equivalent entry point) to
understand the module layout (frontend, backend, common,
render-wasm, exporter, mcp, plugins, library).mem:frontend/core,
mem:backend/core, etc.) when the prompt targets a specific module — this
lets you inject precise vocabulary, file conventions, and test commands
into the refined prompt.This step matters most when the user is preparing a prompt about the Penpot codebase. For generic prompts, focus on prompt-engineering principles and only weave in Penpot context when it is clearly relevant.
question tool to ask them so the
user gets a structured multi-choice UI; reserve a plain ## Clarifying questions markdown section for cases where the question tool is
unavailable or the question is genuinely open-ended.Apply these techniques when refining prompts:
grep, glob, read, bash, etc.) so the model uses the

references instead of "the codebase").Deliver the result in the response as two clearly separated blocks:
If you asked clarifying questions via the question tool, stop and wait for
the answers before producing a refined prompt. If the question tool was not
available and you asked the questions in chat, list them in a separate
Clarifying questions section above the refined prompt and stop — do not
produce a refined prompt until the user answers. If the user explicitly told
you to proceed without questions (e.g. "just rewrite it"), make reasonable
assumptions and note them under Assumptions made in the rationale block.
Always persist the refined prompt to disk so it can be re-used later, versioned in git, and shared with other agents. The response still contains the prompt and rationale blocks; the file is an additional artifact, not a replacement.

Refine and improve a user-supplied prompt for maximum clarity and effectiveness using prompt-engineering best practices and Penpot project context.
Refine Prompt fits situations like: tasks that involve Prompt engineering.
Run `npx skills add penpot/penpot --skill refine-prompt -a claude-code`. Or copy the skill folder (.agents/skills/refine-prompt in penpot/penpot) into .claude/skills/refine-prompt in your project. Claude Code loads it when a task matches its description.
Run `npx skills add penpot/penpot --skill refine-prompt -a codex`. Or copy the skill folder (.agents/skills/refine-prompt in penpot/penpot) into .agents/skills/refine-prompt in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add penpot/penpot --skill refine-prompt -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/refine-prompt, .gemini/skills/refine-prompt, .github/skills/refine-prompt and .opencode/skills/refine-prompt in your project.
SKILL.md names no scripts, command-line tools or credentials: Refine Prompt is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Refine Prompt is published under the MPL-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
