What it does
Design Deck is an agent skill from nicobailon/pi-design-deck. Present visual options for architecture, UI, and code decisions with high-fidelity side-by-side previews. For comparing approaches visually — code diffs, diagrams, UI mockups, images — not for gathering structured input (use interview for that). Supports previewBlocks (code, mermaid, image, html), previewHtml, generate-more loops, and plan/PRD-driven flows.
Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files (for example `references/component-gallery/INDEX.md`, `references/component-gallery/LOOKUP.md` and `references/component-gallery/components.md`).
It sits in Product & Project Management, covering Diagrams, PRD writing and UI design. It works with Mermaid. The repository describes itself as: Visual design deck for presenting multi-slide options with high-fidelity previews.
When your agent uses it
- Tasks that involve Diagrams
- Tasks that involve PRD writing
- Tasks that involve UI design
Example prompts
- “/design-deck”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read the plan in full. Also read the actual codebase files it references — not just the sections mentioned, but enough surrounding code to…
- Identify the key design and architecture decisions embedded in the plan. Not every section is a decision — focus on points where multiple…
- Build a slide for each decision point. Options should be faithful to the plan's goals but offer genuinely different approaches.
- Reference specific plan sections in aside text and recommendations.
What it can do on your machine
Read from SKILL.md and the folder at commit ddf9089. 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 (its code samples are bash and json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
component.gallery
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
Design Deck loads about 4.3k tokens when it runs, and up to ~195k if it reads all its reference files. Until then it costs about 93 tokens; SKILL.md has 2,043 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 2,043 words (~4,251 tokens).
“Use this skill when the task requires presenting multiple visual directions and collecting explicit user choices. Load this skill before building any deck to get the full format reference.”
