Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is --source ./fastlane/metadata/android \.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

gplay-migrate-fastlane 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 12d 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.

Fastlane Migration

Use this skill when you need to migrate from Fastlane supply to the gplay CLI.

Preconditions

  • Existing Fastlane metadata directory structure.
  • gplay CLI installed and authenticated.
  • Familiarity with the source Fastlane directory layout.

Migrate Command

Basic migration

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata

Dry run (preview without writing files)

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --dry-run

Migrate specific locales only

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales en-US,es-ES,fr-FR

Dry run with specific locales

gplay migrate fastlane \
  --source ./fastlane/metadata/android \
  --output-dir ./metadata \
  --locales en-US,ja-JP \
  --dry-run

Flags

Flag Description Required
--source Path to Fastlane metadata directory Yes
--output-dir Output directory for gplay metadata Yes
--dry-run Preview changes without writing files No
--locales Comma-separated list of locales to migrate No (all by default)

What Gets Migrated

The command converts the Fastlane directory structure into the format used by gplay's file-based metadata commands (metadata pull / metadata push / metadata validate):

What ships with it

1 file 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.

Changes

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.
