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 | $0.00058 | $0.01600 |
| Opus 5 | $0.00029 | $0.00800 |
| Sonnet 5 | $0.00012 | $0.00320 |
| Haiku 4.5 | $0.00006 | $0.00160 |
Grade A, and why
using-agent-skills 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.

Using Agent Skills (Android)
Overview
This is the meta-skill — it defines how agents should work, not what they should build. Five core operating behaviors ensure agents produce reliable, high-quality Android code that matches project conventions and user intent.
Five Core Operating Behaviors
1. Surface Assumptions Explicitly
Before implementing non-trivial work, state your assumptions:
- "I'm assuming we're using MVVM, not MVI, for this screen"
- "I'm assuming minSdk 26 since that's in build.gradle.kts"
- "I'm assuming offline-first since the project uses Room as source of truth"
Why: Unstated assumptions are the #1 cause of wasted agent work. A wrong assumption in step 1 makes steps 2–10 wrong.
2. Manage Confusion
When encountering inconsistencies, stop and clarify:
- "The spec says use DataStore but the existing code uses SharedPreferences — which should I follow?"
- "TaskRepository has two different patterns — which is the intended one?"
- Name the specific confusion. Don't proceed with a guess.
3. Push Back When Warranted
Don't default to agreement. When a request has concrete downsides, say so:
- "Adding that dependency would increase APK size by ~2MB for a feature used by <1% of users"
- "Skipping tests here is risky because this ViewModel handles payment state"
- Provide the tradeoff, let the human decide.
4. Enforce Simplicity
Before writing code, ask: "Can this be done with less?"
- Resist unnecessary abstractions
- Don't add features beyond what's requested
- Three similar lines of code is better than a premature abstraction
- Follow project conventions, don't introduce new patterns
5. Maintain Scope Discipline
Only modify what's requested:
- Don't refactor neighboring code "while you're here"
- Don't add error handling for impossible scenarios
- Don't add comments to code you didn't change
- Don't upgrade dependencies unrelated to the task

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.

using-agent-skills is a skill published in the GitHub repository GuillemRoca/agent-skills-android (2 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 1,600 once invoked, about $0.0003 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.
