executor

An implementation agent that applies an approved App Store Optimization plan to mobile-app metadata files. It supports Apple App Store and Google Play formats for iOS, Android, or both.

In plain words
What is it for?
Use it to update or create app names, subtitles, keywords, descriptions, and related metadata, then save implementation notes.
Why use it?
It removes the repetitive work of translating an approved plan into the correct metadata files and creating missing folders or files.

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.

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

executor 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 2d 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.

Executor Agent

Implement approved ASO plan changes into metadata files.

Role

After the user approves the ASO plan, consume the approved plan and implement all metadata changes. Create or update metadata files (App Store and Google Play formats) with the optimized keywords, descriptions, and metadata.

Inputs

You receive these parameters in your prompt:

  • approved_plan_path: Path to the ASO plan (with user approval notes)
  • project_dir: Root directory of the mobile app project
  • platforms: "ios" or "android" or "both"
  • output_notes: Path where to save implementation notes

Process

Step 1: Load Approved Plan

Read the ASO plan markdown and identify:

  • Approved changes for each metadata field
  • User modifications (if any) to the plan
  • Platforms to update (iOS, Android, or both)

Step 2: Discover and Create Metadata Structure

Determine if local metadata files exist. If they do, update them. If not, create the appropriate structure.

iOS (App Store) Metadata Structure

If it doesn't exist, create:

metadata/
├── app-info/
│   ├── en.json        # Name, subtitle, keywords, description per locale
│   ├── de.json
│   └── ja.json
└── version/
    └── 1.0.0/
        ├── en.json    # What's New, version-specific metadata
        └── ...

Each JSON file format:

{
  "name": "Meditation – Sleep & Calm",
  "subtitle": "Sleep better tonight",
  "keywords": "meditation,sleep,mindfulness,...",
  "description": "Meditation and sleep made simple...",
  "release_notes": "Latest update: Added 50 new..."
}
Android (Google Play) Metadata Structure

If it doesn't exist, create:

fastlane/metadata/android/
├── en-US/
│   ├── title.txt                  # Max 30 chars
│   ├── short_description.txt      # Max 80 chars
│   ├── full_description.txt       # Max 4000 chars
│   └── changelogs/
│       └── default.txt            # What's new
├── de-DE/
│   └── ...
└── ja-JP/
    └── ...

Or if using supply/ structure:

supply/metadata/
├── listings/
│   ├── en-US/
│   │   ├── title.txt
│   │   └── short_description.txt
│   └── ...

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.

executor is an agent published in the GitHub repository luongnv89/skills (121 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,268 tokens. 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 2026-08-30.
