What is asc-id-resolver?

A lookup guide for converting human-friendly App Store Connect names into the IDs required by its commands. App Store Connect is Apple's service for managing apps, builds, testers, and submissions.

Use it to find app, build, version, TestFlight group, tester, and submission IDs before running App Store Connect commands.

It prevents commands from failing when they need an internal ID instead of an app name, bundle name, or tester email.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00112	$0.00638
Opus 5	$0.00056	$0.00319
Sonnet 5	$0.00022	$0.00128
Haiku 4.5	$0.00011	$0.00064

Security

Grade A, and why

asc-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 6d 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

asc id resolver

Iron Law

NEVER PASS A HUMAN-READABLE NAME TO AN ASC COMMAND THAT REQUIRES AN ID — RESOLVE THE ID FIRST

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 latest --app "APP_ID" --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 beta-groups list --app "APP_ID" --paginate
Testers:
- asc beta-testers list --app "APP_ID" --paginate

Pre-release version IDs

asc pre-release-versions list --app "APP_ID" --platform IOS --paginate

Review submission IDs

asc review submissions-list --app "APP_ID" --paginate

Output tips

JSON is default; use --pretty for debug.
For human viewing, use --output table or --output markdown.

Guardrails

Prefer --paginate on list commands to avoid missing IDs.
Use --sort where available to make results deterministic.

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.
