Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00031 | $0.00745 |
| Opus 5 | $0.00015 | $0.00373 |
| Sonnet 5 | $0.00006 | $0.00149 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
android-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 8d 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Implement or migrate modern Android navigation without breaking screens, route arguments, deep links or back stack behavior.
When to use
- Adding Navigation 3 to an Android app.
- Migrating from Navigation Compose or custom navigation.
- Fixing typed routes, deep links, nested graphs or back stack issues.
Inputs to inspect
build.gradle.ktsandlibs.versions.tomlMainActivity.ktand app entry pointsNavHost, routes and feature navigation filesAndroidManifest.xmldeep linksscreens/*and ViewModel event flow
Required workflow
- Map current destinations, arguments and deep links.
- Choose typed routes or preserve the existing route convention.
- Move navigation decisions to route-level event handling.
- Add or update navigation tests for critical flows.
- Validate back behavior, process recreation and deep links.
Rules
- Do not pass large objects as route arguments.
- Do not put business logic inside route definitions.
- Do not create duplicate NavHost owners.
- Preserve existing deep links unless the user approves a migration.
- Prefer typed route patterns when the project already uses them.

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

android-navigation-3 is a skill published in the GitHub repository GDvega/super-android-kotlin-firebase-skill (2 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 745 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
