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 | $0.00044 | $0.01331 |
| Opus 5 | $0.00022 | $0.00665 |
| Sonnet 5 | $0.00009 | $0.00266 |
| Haiku 4.5 | $0.00004 | $0.00133 |
Grade A, and why
asc-metadata-sync 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 4d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
asc metadata sync and localization
Use this skill to keep local metadata in sync with App Store Connect, and to translate metadata to multiple languages.
Command discovery
- Always confirm flags with
--helpfor the exactascversion. - Prefer explicit long flags (
--app,--version,--version-id,--type,--app-info). - Default output is JSON; use
--output tableonly for human verification steps. - Prefer deterministic ID-based operations.
Two Types of Localizations
1. Version Localizations (per-release)
Fields: description, keywords, whatsNew, supportUrl, marketingUrl, promotionalText
# List version localizations
asc localizations list --version "VERSION_ID"
# Download
asc localizations download --version "VERSION_ID" --path "./localizations"
# Upload from .strings files
asc localizations upload --version "VERSION_ID" --path "./localizations"
2. App Info Localizations (app-level)
Fields: name, subtitle, privacyPolicyUrl, privacyChoicesUrl, privacyPolicyText
# First, find the app info ID
asc app-infos list --app "APP_ID"
# List app info localizations
asc localizations list --app "APP_ID" --type app-info --app-info "APP_INFO_ID"
# Upload app info localizations
asc localizations upload --app "APP_ID" --type app-info --app-info "APP_INFO_ID" --path "./app-info-localizations"
Note: If you get "multiple app infos found", you must specify --app-info with the correct ID.
Legacy Metadata Format Workflow
Export current state
asc migrate export --app "APP_ID" --output "./metadata"
Validate local files
asc migrate validate --help
Import updates
asc migrate import --help
Quick Field Updates
Version-specific fields
asc app-info set --app "APP_ID" --locale "en-US" --whats-new "Bug fixes"
asc app-info set --app "APP_ID" --locale "en-US" --description "Your description"
asc app-info set --app "APP_ID" --locale "en-US" --keywords "keyword1,keyword2"
asc app-info set --app "APP_ID" --locale "en-US" --support-url "https://support.example.com"
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.
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.

asc-metadata-sync is a skill published in the GitHub repository Abdullah4AI/apple-developer-toolkit (10 stars, last pushed 3d ago), licensed MIT. It adds 44 tokens to every session and 1,331 once invoked, about $0.0002 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.
