What is navigation-3?

Guidance for using Jetpack Navigation 3, the Android library that controls movement between screens in Jetpack Compose apps. It covers migration, navigation state, deep links, and common screen layouts.

Use it to migrate an Android app to Navigation 3, add deep links, manage multiple backstacks, return results from screen flows, and build layouts such as dialogs, bottom sheets, list-detail, and two-pane screens.

It helps developers move from older navigation setups and avoid designing common navigation behavior from scratch. It also explains how to preserve navigation history and handle different user states.

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 5.1	$0.00080	$0.01286
Opus 5	$0.00040	$0.00643
Sonnet 5	$0.00016	$0.00257
Haiku 4.5	$0.00008	$0.00129

Security

Grade A, and why

navigation-3 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.

Origin

This is a copy

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.
