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.

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 | $0.00115 | $0.02030 |
| Opus 5 | $0.00057 | $0.01015 |
| Sonnet 5 | $0.00023 | $0.00406 |
| Haiku 4.5 | $0.00012 | $0.00203 |
Grade A, and why
google-mobile-ninja 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 7d 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google Mobile Ninja
Jump Skill — Master orchestrator that routes mobile development tasks to 35+ specialized skills from official Google repositories.
Purpose
This skill acts as an intelligent router to the Android, Flutter, and Dart skills library. Instead of manually searching for the right skill, describe your mobile dev task and this skill will:
- Identify the most relevant specialized skill(s)
- Load the full skill instructions on demand
- Execute the task with expert-level mobile knowledge

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.

google-mobile-ninja is a skill published in the GitHub repository fabricioctelles/jump-skills (28 stars, last pushed yesterday), licensed MIT.
