plan-ui-changePlan complex Blazor UI features by decomposing them into focused components.
Plan UI Change is an agent skill from dotnet/skills, published by the product's own GitHub organization. Plan complex Blazor UI features by decomposing them into focused components. USE FOR: building a complex Blazor page with multiple sections, planning component decomposition, designing a multi-section dashboard or layout, breaking down a large UI feature into composable components, pages with sidebars and content panels, any page with 3+ distinct visual sections or multiple interacting sub-features, identifying parent-child relationships and data flow. DO NOT USE FOR: creating new Blazor projects or apps from…
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Blazor. The repository describes itself as: Repository for skills to assist AI coding agents with .NET and C. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 8d670fa. 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 (its code samples are markdown).
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.
Plan UI Change loads about 1.9k tokens when it runs. Until then it costs about 187 tokens; SKILL.md has 724 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 patterns that need a careful read before installing.
**immediately proceed to implement** — never stop at just the plan or ask for confirmation before writing code. The plaAutomated 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/plan-ui-change/SKILL.md (or your agent's skills folder).When asked to build a complex UI feature, plan the component decomposition first, then immediately implement it. A single monolithic page component is almost never the right answer — break the UI into focused, composable components.
Read the request and identify every distinct visual region. Each region that has its own data, behavior, or layout responsibility is a candidate component.
Draw the component tree:
InventoryDashboard (page — owns data, orchestrates layout)
├── StockSummaryBar (read-only stats: total items, low-stock count, value)
├── InventoryFilters (search box, category dropdown, stock-level toggle)
├── InventoryTable (sortable table of products)
│ └── InventoryRow (single product row with inline edit/delete)
└── AddProductForm (slide-out form for new products)Rules for identifying components:
For every component in the tree, determine:
| Component | Action | Render Mode | State Owned | Lines (est.) |
|---|---|---|---|---|
| InventoryDashboard | Create | InteractiveServer | product list, filter state | ~80 |
| StockSummaryBar | Create | (inherits) | none — receives data | ~30 |
| InventoryFilters | Create | (inherits) | search text, selected category | ~60 |
| InventoryTable | Create | (inherits) | sort column, sort direction | ~50 |
| InventoryRow | Create | (inherits) | inline-edit mode flag | ~60 |
| AddProductForm | Create | (inherits) | form model | ~80 |
A page component that exceeds ~200 lines of combined markup + code is too large. If your estimate puts a single component above that, split further.
Identify the state owner for each piece of data, then map how it flows:
InventoryDashboard (owns: products[], filters)
│
├─ [Parameter] products ──→ StockSummaryBar (reads aggregate stats)
│
├─ [Parameter] filters ──→ InventoryFilters
│ └─ EventCallback<Filters> OnFiltersChanged ──→ InventoryDashboard
│
├─ [Parameter] filteredProducts ──→ InventoryTable
│ └─ [Parameter] product ──→ InventoryRow
│ ├─ EventCallback<Product> OnSave ──→ InventoryTable ──→ InventoryDashboard
│ └─ EventCallback<Product> OnDelete ──→ InventoryTable ──→ InventoryDashboard
│
└─ EventCallback<Product> OnProductAdded ←── AddProductFormRules:
[Parameter]EventCallback<T>Before creating a new component, check if an existing component in the project can serve the purpose. Look for:
DataTable<T>, Pagination) that accept templatesIf a component will be used in more than one page, place it in a Shared/ or Components/ folder.
Build bottom-up — leaf components first, then parents that compose them:
Each component should be independently compilable. Never reference a component that doesn't exist yet.
Present the plan briefly, then immediately proceed to implement — never stop at just the plan or ask for confirmation before writing code. The plan is a thinking tool, not a deliverable.

| Anti-Pattern | Why It's Wrong | Correct Approach |
|---|---|---|
| One page component with 500+ lines | Impossible to test, reuse, or maintain | Decompose into focused components |
| Passing 10+ parameters through intermediate components | Parameter drilling obscures intent | Use cascading values or a scoped state service |
| Child component fetching its own data from an API | Multiple components making redundant calls | Parent owns data, passes via parameters |
| Inline rendering of list items with complex markup | Duplicated logic, no reuse, hard to test | Extract item template into its own component |
| Building everything in one file then "refactoring later" | Refactoring rarely happens; the monolith ships | Plan the decomposition upfront |
| Generic components for one-off usage | Over-engineering adds complexity | Only extract generics when reuse is proven |

Plan complex Blazor UI features by decomposing them into focused components. Plan UI Change is an agent skill from dotnet/skills, published by the product's own GitHub organization. Plan complex Blazor UI features by decomposing them into focused components.
Plan UI Change fits situations like: : building a complex Blazor page with multiple sections; planning component decomposition; designing a multi-section dashboard; breaking down a large UI feature into composable components.
Run `npx skills add dotnet/skills --skill plan-ui-change -a claude-code`. Or copy the skill folder (plugins/dotnet-blazor/skills/plan-ui-change in dotnet/skills) into .claude/skills/plan-ui-change in your project. Claude Code loads it when a task matches its description.
Run `npx skills add dotnet/skills --skill plan-ui-change -a codex`. Or copy the skill folder (plugins/dotnet-blazor/skills/plan-ui-change in dotnet/skills) into .agents/skills/plan-ui-change 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 dotnet/skills --skill plan-ui-change -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/plan-ui-change, .gemini/skills/plan-ui-change, .github/skills/plan-ui-change and .opencode/skills/plan-ui-change in your project.
SKILL.md names no scripts, command-line tools or credentials: Plan UI Change 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 flagged 1 warning(s): tells the agent its actions are pre-authorized / not to stop for confirmation. Read the flagged lines before installing; the check is not a guarantee either way.
Plan UI Change is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Plan UI Change: Aspnet Core (fanslead/ReverseProxy.Store, 163 stars), Maui AI Debugging (Redth/Maui.Gtk, 101 stars), Test First (deanhume/html-minifier, 142 stars) and QA Tester (JocysCom/FocusLogger, 213 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
