At a glance

Add modal dialogs and overlay UI with focus trapping. An agent skill from RtlZeroMemory/Rezi.

  • Works in 3 steps: Use ui.modal() directly with a… → Overlay ordering note → Dialog action intent note
  • Implementing confirmations
  • SKILL.md covers When to use, Source of truth, Steps and Verification
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Rezi Modal Dialogs is an agent skill from RtlZeroMemory/Rezi. Add modal dialogs and overlay UI with focus trapping. Use when implementing confirmations, alerts, or layered interfaces.

Its SKILL.md is about 730 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 Frontend & Design. The repository describes itself as: Build TypeScript TUI backed by fast native rendering engine. The licence is Apache-2.0.

When your agent uses it

  • Implementing confirmations
  • Layered interfaces

Example prompts

  • “/rezi-modal-dialogs”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Edit, Write

Workflow steps

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

  1. Use ui.modal() directly with a state-controlled flag
  2. Overlay ordering note
  3. Dialog action intent note

What it can do on your machine

Read from SKILL.md and the folder at commit 671a8a2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Edit
    • Write

    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 typescript).

    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

Rezi Modal Dialogs loads about 731 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 143 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~731

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.

When to use

Use this skill when:

  • Adding confirmation dialogs, alerts, or prompts
  • Building layered/overlay UI
  • Need focus trapping within a dialog

Source of truth

  • packages/core/src/widgets/useModalStack.ts — useModalStack() hook
  • packages/core/src/widgets/types.ts — ModalProps, LayersProps
  • packages/core/src/widgets/ui.ts — ui.modal(), ui.layers()
  • packages/core/src/ui/recipes.ts — recipe.modal() and recipe.surface() for design-system-consistent modal styling

Steps

  1. Use useModalStack() inside a defineWidget:
    typescript
    const modals = useModalStack(ctx);

// Push a modal
modals.push("confirm", {
  title: "Confirm",
  content: body,
  onClose: () => modals.pop(),
});

// Include in view
return ui.layers([mainContent, ...modals.render()]);
Option B: ui.modal (simple single modal)

  1. Use ui.modal() directly with a state-controlled flag:

    typescript
    return ui.layers([
  mainContent,
  ...(state.showModal
    ? [
        ui.modal({
          id: "confirm-modal",
          title: "Confirm",
          initialFocus: "confirm-ok",
          returnFocusTo: "open-confirm",
          onClose: () => app.update((s) => ({ ...s, showModal: false })),
          content: ui.text("Are you sure?"),
          actions: [
            ui.button({
              id: "confirm-cancel",
              label: "Cancel",
              intent: "secondary",
              onPress: () => app.update((s) => ({ ...s, showModal: false })),
            }),
            ui.button({
              id: "confirm-ok",
              label: "OK",
              intent: "primary",
              onPress: () => app.update((s) => ({ ...s, showModal: false })),
            }),
          ],
        }),
      ]
    : []),
]);

  2. Overlay ordering note:

    • Modal, dropdown, and toast overlays share unified z-ordering through the LayerRegistry.
    • Prefer ui.layers([...]) as the common overlay composition root.

  3. Dialog action intent note:

    • Use intent to communicate action semantics in modal/dialog button rows.
    • Recommended mapping: confirm/continue -> primary, cancel/back -> secondary, destructive -> danger, positive approval -> success, cautionary acknowledgment -> warning.

Verification

  • Modal opens and closes correctly
  • Focus traps within the modal (Tab doesn't escape)
  • Focus returns to previous element on close
