What it does
Nalu Maui Virtualscroll is an agent skill from nalu-development/nalu. Nalu.Maui.VirtualScroll: high-performance virtualized list (RecyclerView/UICollectionView). Use when building lists, carousels, sectioned data, pull-to-refresh, drag-and-drop reorder, or replacing MAUI CollectionView for performance.
Its SKILL.md is about 1.3k 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 Mobile, covering Cross-platform mobile apps. The repository describes itself as: Provides .NET MAUI packages to help with everyday challenges.
When your agent uses it
- Pull-to-refresh
- Drag-and-drop reorder
- Replacing MAUI CollectionView for performance
Example prompts
- “/nalu-maui-virtualscroll”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Use nalu:ViewBox in item templates.
- Keep item templates simple.
- For AOT: use adapter factory methods; do not bind ObservableCollection directly.
- Prefer ObservableRangeCollection for bulk updates.
- Do not call GetVisibleItemsRange() in scroll handlers; use ScrollPercentageY or RemainingScrollY for infinite scroll.
What it can do on your machine
Read from SKILL.md and the folder at commit 8109e93. 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 xml and csharp).
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):
nalu-development.github.iogithub.com
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
Nalu Maui Virtualscroll loads about 1.3k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 352 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 352 words (~1,329 tokens).
“High-performance virtualized scrolling (Android RecyclerView, iOS UICollectionView). Replaces MAUI CollectionView with dynamic item sizing, headers/footers, sections, carousel, pull-to-refresh, and drag-and-drop.”
