using-agent-skills

using-agent-skills is a skill for Claude Code from GuillemRoca/agent-skills-android. It costs 58 tokens per session (1,600 once invoked), scanned A, original, MIT.

A general working guide for coding agents, focused on stating assumptions, resolving confusion, giving justified pushback, keeping solutions simple, and controlling scope.

In plain words
What is it for?
Use it when starting work or choosing another skill, especially for Android projects where architecture, minimum versions, and existing patterns may affect the solution.
Why use it?
It helps prevent work based on hidden assumptions or unresolved contradictions, which can lead to incorrect implementation.

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.

Security

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

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.
