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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.00397 |
| Opus 5 | $0.00017 | $0.00198 |
| Sonnet 5 | $0.00007 | $0.00079 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
appstore-id-resolver 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 10d 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.
What it actually says
App Store ID Resolver
Use this skill to map names to IDs needed by other commands.
App ID
- By bundle ID or name:
asc apps list --bundle-id "com.example.app"asc apps list --name "My App"
- Fetch everything:
asc apps --paginate
- Set default:
ASC_APP_ID=...
Build ID
- Latest build:
asc builds info --app "APP_ID" --latest --version "1.2.3" --platform IOS
- Recent builds:
asc builds list --app "APP_ID" --sort -uploadedDate --limit 5
Version ID
asc versions list --app "APP_ID" --paginate
TestFlight IDs
- Groups:
asc testflight groups list --app "APP_ID" --paginate
- Testers:
asc testflight testers list --app "APP_ID" --paginate
Pre-release version IDs
asc testflight pre-release list --app "APP_ID" --platform IOS --paginate
Review submission IDs
asc review submissions-list --app "APP_ID" --paginate
Output tips
- Output defaults are TTY-aware: interactive terminals use tables, while pipes, files, and CI use JSON.
- For automation, always pass
--output json; use--prettyonly when a human needs formatted JSON. For human viewing, use--output tableor--output markdown.
Guardrails
- Prefer
--paginateon list commands to avoid missing IDs. - Use
--sortwhere available to make results deterministic.
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.

appstore-id-resolver is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 13d ago), licensed MIT. It adds 35 tokens to every session and 397 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 2026-08-30.
