mozaiks: Skill for Claude Code

.agents/skills/add-page/SKILL.md

add-page is a skill for Claude Code from BlocUnited-LLC/mozaiks. It costs 20 tokens per session (2,663 once invoked), scanned A, original, MIT.

A method for adding a frontend page to a Mozaiks application using a YAML page schema. YAML is a plain-text format for describing structured settings, while the platform renders the page from predefined interface components.

In plain words
What is it for?
It is for creating pages with grids, sidebars, full-width layouts, split layouts, and different application shell modes using files under the app/ui/pages directory.
Why use it?
It lets developers describe a page's layout and content without writing the page's raw interface code. The existing platform shell and renderer assemble the result automatically.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-page scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before starting: git fetch origin && gh pr list --state open && git log origin/main --oneline -3 — if another agent has an open PR touching the same files you need, wait for it to merge or branch off it instead of main.

Help the user add a page to an existing Mozaiks application.

Pages in Mozaiks are declared as YAML schemas (AppPageSchema) — not raw React. The platform shell renders them automatically using pre-built primitives.


What a Page Is

app/ui/pages/
└── <name>.yaml       ← the page schema

# Or folder form:
app/ui/pages/<name>/
└── page.yaml

The SchemaPage route component fetches /api/pages/<name>, and PageRenderer assembles the layout from the schema using the primitive registry.


Steps to Add a Page

1. Create the page schema

touch app/ui/pages/<name>.yaml

2. Write the schema

name: <name>
title: <Page Title>
layout: grid               # grid | sidebar | full-width | split
shell_mode: standard       # standard | workspace | conversation | focused | immersive | public

sections:
  - id: <section_id>
    title: <Section Title>
    primitive: DataTable   # see primitives below
    config:
      columns:
        - { key: id,    label: ID }
        - { key: name,  label: Name }
    api_endpoint: /api/modules/<module>/<action>   # optional live data

3. Restart the backend

mozaiks serve .

Pages are loaded at startup. The route /<name> is served automatically.

4. Add shell access when needed

If the page should be globally reachable, prefer route-level navigation metadata on the page itself:

navigation:
  scope: global
  icon: dashboard
  order: 20

Use scope: local for workspace/module subsections that should render through local navigation instead of crowding the global shell.

Choose shell_mode for route chrome:

  • standard: normal app page.
  • workspace: dense dashboard, admin/profile/module workspace, or local nav surface.
  • conversation: chat, DM, inbox thread, or support conversation where the composer owns the bottom edge.
  • focused: onboarding, setup, review, approval, or checkout-style route.
  • immersive: map, canvas, media, game, or full-viewport route.
  • public: legal, marketing, or unauthenticated information route.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
