What it does
Good Design is an agent skill from kipperacademy/skillpper. Design and audit product experiences for ethical conversion, activation, retention, and expansion using product and behavioral-design principles. Use for SaaS UX, landing pages, onboarding, dashboards, forms, pricing, and feature decisions—not for visual styling alone.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `agents/openai.yaml`, `references/fontes.md` and `references/fundamentos.md`).
It sits in Frontend & Design, covering Landing pages. The repository describes itself as: Practical skills for developers and their AI coding agents 🤓.
When your agent uses it
- Feature decisions—not for visual styling alone
- Tasks that involve Landing pages
Example prompts
- “/good-design”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Who is the ICP here? What is their urgent job, context, level of awareness, and actual willingness to invest effort?
- What promise got them here? Is the product able to show the corresponding result—not merely its mechanics—within a credible time?
- What one behavior predicts durable value? Define the activation event, its expected time-to-value (TTV), and the next repeat action.
- Where does the journey actually fail? Use funnel data, support issues, interviews, usability sessions, and session replays. The intended…
- What is the single next action? Can someone scanning the screen tell what to do, why it matters, and what happens after?
- What mental work is unnecessary? Count choices, fields, jargon, steps, waits, and competing visual signals. Remove or defer administrative…
- What doubt, risk, or loss is present at this moment? Put honest proof, specificity, privacy/payment reassurance, progress, or recovery…
- How does continued use compound value? Look for useful history, personalization, workflow embedding, collaboration, habit, and recurring…
- What business result should improve, and what guardrail protects users? Name one measurable hypothesis (for example activation rate, TTV…
What it can do on your machine
Read from SKILL.md and the folder at commit 163871c. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Good Design loads about 2k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 1,044 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,044 words (~1,987 tokens).
“Use this skill to make a product experience easier to understand, quicker to deliver its promised value, and worth returning to. The desired outcome is durable user value and a healthier business—not engagement tricks, coerced consent, or harder cancellation.”
