Tasks that involve Authentication
SKILL.md covers Workflow, Side Files, Output and Mobile-First Constraints
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/checklist.md`).

It sits in Backend & APIs, covering Authentication. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

When your agent uses it

Tasks that involve Authentication

Example prompts

“/login-flow”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Read reference files first (see below)
Clarify auth method: phone/SMS, password, or social SSO
Checklist gate — verify P0 items before emitting
Build the HTML prototype with proper states (default, loading, error)
Wrap in tag referencing the output file

What it can do on your machine

Read from SKILL.md and the folder at commit d9dd6fe. 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

Login Flow loads about 334 tokens when it runs, and up to ~498 if it reads all its reference files. Until then it costs about 14 tokens; SKILL.md has 152 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~14
When it runs · the whole SKILL.md, loaded when a task matches: ~334
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~498

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

The full file from nexu-io/open-design at commit d9dd6fe, republished under its Apache-2.0 licence (© nexu-io). 152 words, ~334 tokens.
