What is implementing-navigation?

A guide to menus, tabs, breadcrumbs, page links, and routing, which determines how users and requests move through an application. It covers frontend navigation and backend route configuration.

Use it to build menus, sidebars, tabs, breadcrumbs, pagination, mobile navigation, command palettes, multi-step flows, or keyboard-accessible routes.

It helps structure complex applications so users can find screens and the server can send each request to the right handler.

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.

Model	Per session	Once invoked
Fable 5	$0.00050	$0.01450
Opus 5	$0.00025	$0.00725
Sonnet 5	$0.00010	$0.00290
Haiku 4.5	$0.00005	$0.00145

Security

Grade A, and why

implementing-navigation 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 3d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (examples/django_urls.py, examples/fastapi_routes.py, examples/flask_routes.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

This skill provides comprehensive guidance for implementing navigation systems across both frontend and backend applications. It covers client-side navigation patterns (menus, tabs, breadcrumbs) and routing (React Router, Next.js) as well as server-side route configuration (Flask, Django, FastAPI).

When to Use

Use this skill when:

Building primary navigation (top, side, mega menus)
Implementing secondary navigation (breadcrumbs, tabs, pagination)
Setting up client-side routing (React Router, Next.js)
Configuring server-side routes (Flask, Django, FastAPI)
Creating mobile navigation patterns (hamburger, bottom nav)
Implementing keyboard-accessible navigation
Building command palettes or search-driven navigation
Creating multi-step wizards or steppers
Ensuring WCAG 2.1 AA compliance for navigation

Information Architecture → Navigation Pattern

Flat (1-2 levels)      → Top Navigation
Deep (3+ levels)       → Side Navigation
E-commerce/Large       → Mega Menu
Linear Process         → Stepper/Wizard
Long Content          → Table of Contents
Power Users           → Command Palette
Multi-section Page    → Tabs
Large Data Sets       → Pagination

Primary Navigation Patterns

Top Navigation (Horizontal)

Best for shallow hierarchies, marketing sites
5-7 primary links maximum for cognitive load
See references/menu-patterns.md for implementation

Side Navigation (Vertical)

Best for deep hierarchies, admin panels, dashboards
Supports multi-level nesting and collapsible sections
See references/menu-patterns.md for sidebar patterns

Mega Menu

Best for e-commerce, content-heavy sites
Rich content with images and descriptions
See references/menu-patterns.md for mega menu structure

Secondary Navigation Components

Breadcrumbs

Shows hierarchical path and current location
Essential for deep sites and e-commerce
See references/navigation-components.md for breadcrumb patterns

What this file has done since we first saw it

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.
