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 | $0.00032 | $0.00373 |
| Opus 5.5 | $0.00013 | $0.00149 |
| Sonnet 5.5 | $0.00006 | $0.00075 |
| Haiku 4.5 | $0.00003 | $0.00037 |
Grade A, and why
appstore-build-monitor 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 1mo 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 Build Monitor
Use this skill to manage build state, processing, and retention.
Find the right build
- Latest build:
asc builds info --app "APP_ID" --latest --version "1.2.3" --platform IOS
- Next safe build number:
asc builds next-build-number --app "APP_ID" --version "1.2.3" --platform IOS
- Recent builds:
asc builds list --app "APP_ID" --sort -uploadedDate --limit 10
Inspect processing state
asc builds info --build-id "BUILD_ID"
Distribution flows
- Prefer end-to-end:
asc publish testflight --app "APP_ID" --ipa "./app.ipa" --group "GROUP_ID" --waitasc publish appstore --app "APP_ID" --ipa "./app.ipa" --version "1.2.3" --wait --submit --confirm
Cleanup
- Preview expiration:
asc builds expire-all --app "APP_ID" --older-than 90d --dry-run
- Apply expiration:
asc builds expire-all --app "APP_ID" --older-than 90d --confirm
- Single build:
asc builds expire --build-id "BUILD_ID" --confirm
Notes
asc builds uploadprepares upload operations only; useasc publishfor end-to-end flows.- For long processing times, use
--wait,--poll-interval, and--timeoutwhere supported.
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-build-monitor is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 373 once invoked, about $0.0001 per session on Opus 5.5. 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.

lov-app-release
A release workflow for publishing one app version to declared channels such as iOS, Android, GitHub, a website, and documentation. It checks signing, build artifacts, and remote status rather than treating a successful build as a completed release.

Use when committing, branching, resolving conflicts, splitting uncommitted work in a messy working tree into clean atomic commits, opening or reviewing a pull request (PR), pushing to a remote, or when you need to organize work across multiple…

Roll a release back for real when post-deploy regression goes red — apc release rollback flips the current version to pulled and the last good version back to current in the release ledger, and (with --mirror) repoints the bare mirror ref.

Cut a release tag behind a real tier gate and cloud approval readback. The approval, task, approved commit, and resulting tag are bound; self-approval and HEAD drift fail closed. Prod prefixes remain refused.
