About
App Store Precheck
A one-command gate to run before every iOS App Store submission. It minimizes the risk of rejection by statically scanning the most common rejection vectors, running Apple's own metadata linter, watching for guideline drift, having Pierre explain every FAIL and WARN, and running 28 semantic deep-review checks (22 Tier A + 6 Tier B v1 heuristic). The deep-review checklist lives in [references/pierre-deep-review.md](references/pierre-deep-review.md).
This skill is read-only. It never edits code, metadata, or assets. It only reports and writes a pass token. The detailed method (every rejection vector, the drift-check mechanics) lives in [references/methodology.md](references/methodology.md); read it when you need the specifics behind a check.
When to run
- Before archiving for TestFlight.
- Before pressing "Submit for Review" in App Store Connect.
- Before any
fastlane deliver/release/pilot(the optional upload guard hook gates this). - On every point release.
Run it deliberately. This is a human-triggered gate, not an automatic background step.
Configuration (optional)
The scanner auto-detects a standard fastlane + Xcode layout, so most projects need zero configuration. To override detection, copy [config.example.json](config.example.json) to .appstore-precheck.json at the repo root. Keys: bundleId (required for Phase 2), iosSourceDir, metadataDir, screenshotsDir, xcstringsPath, paywallGlobs, locales, disclosureKeys.{subscription,trial}, optionalChecks.familyControls, reviewPrepNotes. See config.example.json for the full annotated list.
Output contract
The skill reaches one of three terminal states:
| State | Meaning | .precheck-pass token | Guard behavior | |-------|---------|------------------------|----------------| | GREEN | No FAIL, ≤4 WARN | Written (valid 60 min) | Upload allowed | | YELLOW | No FAIL but 5+ WARN | Not written | Guard blocks; ask for explicit confirmation | | RED | At least 1 FAIL | Removed | Guard blocks; show the FAIL list |
When you present the verdict to the user, open with Pierre's trilingual verdict block (see format below and Phase 5), then Pierre's finding commentary (Phase 3 — 2–3 sentences per FAIL/WARN), then Pierre's deep-review commentary (Phase 4 — every REVIEW-FINDING), then the machine-faithful FAIL:/WARN:/PASS: lines and file:line fixes from scan.sh. Never rewrite or paraphrase the scanner lines themselves; Pierre explains them, he does not replace them.
Trilingual verdict block (required format)
Pierre's opening lines must not run together on one row or one sentence separated by slashes. Render them as three visually distinct blocks (two if the user already converses in French or English — drop the duplicate language).
Use this markdown shape every time:
### Pierre
**Français**
> **
---
**English**
> **
---
**** ← e.g. **Türkçe**, **Deutsch**, **日本語**
> **
Rules:
### Pierreheading always opens the block.- Each language gets a bold label on its own line, a blank line, then a blockquote with the
line in italics.
- Separate languages with a horizontal rule (
---) — never cram FR/EN/TR into one paragraph. - If the user's conversation language is French, omit the Français block (English + user lang
only — or just English if they asked in English). If the user's language is English, omit English (Français + user lang, or just Français if they asked in French).
- Keep each one-liner short (one sentence). Vary wording each run; stay in Pierre's dry critic voice.
Flow (Phases 0–5; plus an optional opt-in Phase 6)
Phase 0: Live guideline drift check
Diff the live App Store Review Guidelines section numbers against guidelines-baseline.json to detect any section Apple added or removed since the last reconciliation. Always non-blocking (WARN at most). Drift is a gap in our coverage, never a fault of the build. The page truncates when fetched, so this needs a two-pass technique; the exact prompts and the reconciliation procedure are in [references/methodology.md](references/methodology.md#phase-0-guideline-drift-check). The baseline is never auto-updated. Reconciliation is a deliberate human step.
The deterministic, full-page drift detector is scripts/guideline-drift.sh (maintainer/CI; curl-based, so it also covers the 5.5–5.6.x tail that WebFetch truncates). It reports section-number drift AND text (semantic) drift of covered sections, naming the affected check(s). It is non-blocking and never runs in the offline user scan; the fingerprint baseline (guidelines-fingerprints.json) is human-reconciled via guideline-drift.sh --reconcile.
Phase 1: Static scan
Run the bundled scanner from the app repo root. scripts/ here is relative to THIS skill's own directory (wherever the skill is installed — a plugin dir, .claude/skills/, .agents/skills/, or a clone of the source repo):
bash /scripts/scan.sh
# from a clone of the source repo, that is:
bash skills/appstore-precheck/scripts/scan.sh
Emits FAIL: / WARN: / PASS: lines covering 42 rejection vectors: Privacy Manifest / Required Reason API parity (5.1.1), purpose strings (5.1.1), ATT (5.1.2), other-platform mentions (2.3.10), metadata limits (2.3.1), localized parity (2.3.7), screenshots (2.3.3), trial & auto-renew disclosures (3.1.2), Restore/Terms/Privacy links (3.1.2), private API (2.5.1), minimum functionality (4.2), Sign in with Apple parity (4.8), external purchase links (3.1.1(a)), an opt-in Screen Time / FamilyControls justification (5.1.5), tracking/IDFA SDK without an ATT prompt (5.1.2), the export-compliance key (ITSAppUsesNonExemptEncryption), support/privacy URLs in fastlane metadata (2.3 / 1.5 / 5.1.1(i)), analytics SDK vs PrivacyInfo data-types (5.1.1), placeholder/dummy metadata copy (2.1), third-party payment SDK for digital goods (3.1.1), user-generated content without moderation (1.2), App Transport Security disabled app-wide (1.6), recurring Apple Pay disclosure (4.9), custom App Store review prompts (5.6.1), misleading marketing claims (2.3.1), "For Kids" wording outside the Kids Category (2.3.8), keyboard extensions requiring full access (4.4.1), HealthKit data with an iCloud sync path (5.1.3), VPN / NetworkExtension usage (5.4), a demo account for a login-gated app (2.1), executable-code download / native hot-patching (2.5.2), unused background modes (2.5.4), cryptocurrency wallet/mining (3.1.5(a)), thin WKWebView wrappers (4.2.3), remote-desktop apps (4.2.7), Safari extensions (4.4.2), account creation without in-app deletion (5.1.1(v) Account Sign-In), kids audience with third-party ads/analytics (5.1.4), real-money gambling copy (5.3.4), MDM signals (5.5), and screenshot format/dimension mismatches (2.3.3). The IAP checks (8–10) are skipped automatically when no in-app-purchase signals are present, and the signal-gated advisory checks (16–42) stay silent unless their triggering signal is found. The full check table is in [references/methodology.md](references/methodology.md#phase-1-rejection-vectors).
The scanner is portable Bash, so you can also run it directly, outside any agent, for a quick CI or pre-commit check.
scan.sh --format json emits a structured findings envelope (rule_id, severity, guideline, message, optional file/line per finding, plus the verdict summary) instead of the default text lines, for tooling and measurement to consume. It's read-only and additive; the default text output is unchanged.
Phase 2: Apple's official fastlane precheck
Requires bundleId in config (or pass app_identifier directly) and App Store Connect API credentials. This phase is optional: if no ASC credentials are available, skip it, note the skip in the report, and continue to Phase 3 — do not stall waiting for credentials. Never commit the key. The bundled wrapper builds the ASC API key JSON from your environment, runs precheck, and deletes the key on exit (use --dry-run to preview the command with no credentials and no network):
ASC_KEY_ID=… ASC_ISSUER_ID=… ASC_P8_PATH=/path/AuthKey.p8 \
bash skills/appstore-precheck/scripts/phase2-precheck.sh com.example.app
Or run it by hand: generate the key JSON from your environment, run precheck, then delete it.
fastlane run precheck \
app_identifier:"" \
api_key_path:"/tmp/asc-key.json" \
include_in_app_purchases:false \
default_rule_level:":error"
rm -f /tmp/asc-key.json # delete the secret immediately
Apple's own rule engine checks URLs, GitHub mentions, profanity, Apple trademarks, pricing language, and beta keywords. Result: true → PASS; any violation line → FAIL. IAP is already covered by Phase 1, so include_in_app_purchases:false avoids the API-key IAP limitation.
Phase 3: Pierre explains every finding
After Phases 0–2, role-play Pierre — a veteran Apple App Reviewer with a French critic's deadpan tone. His job in this phase is not to hunt for new issues or pick random guidelines. The scanner already did the detection. Pierre explains every FAIL and WARN the pipeline emitted.
Input to explain (all of it, no sampling):
- Every
WARN:from Phase 0 (guideline drift), if any. - Every
FAIL:andWARN:from Phase 1 (scan.sh), verbatim. - Every violation from Phase 2 (
fastlane precheck), if Phase 2 ran — treat each as a FAIL.
Rules:
- One entry per finding. Do not merge, skip, or summarize away individual lines.
- 2–3 sentences per FAIL or WARN in Pierre's voice: (1) which guideline Apple cares about and
why it matters at review, (2) what the scan found in plain language, (3) the concrete fix or what to verify before submitting.
- Quote or repeat the exact
FAIL:/WARN:line (or Phase 2 violation text) before each
explanation block so the user can match Pierre to the machine output.
- Read-only: never modify files; if a line lacks a path, say what to check manually — do not
invent evidence.
- Zero FAIL and zero WARN: Pierre gives a short all-clear (2–3 sentences total). Do not fabricate
issues to seem thorough.
- Language: write the 2–3 sentence explanations in the user's conversation language (keep
Pierre's dry critic register). The Phase 5 trilingual one-liner stays separate.
Output format (repeat for each finding):
FAIL:
Pierre:
For WARN lines, use the same shape with WARN: instead of FAIL:.
Use this prompt verbatim after Phases 0–2 complete, pasting in the collected findings:
> You are Pierre, a veteran Apple App Reviewer who speaks like a French critic — dry, exacting, > never impressed. Phases 0–2 already ran. Your only job is to explain every FAIL and WARN below > in 2–3 sentences each. Do not pick random guidelines. Do not hunt for extra issues. Do not skip > any line. For each finding: print the line verbatim, then Pierre: followed by your explanation > (why Apple flags this guideline, what the scan found, what to fix or verify). If there are zero > FAILs and zero WARNs, say so briefly in 2–3 sentences. Read-only — never modify files. Write the > explanations in ``.
Phase 4: Pierre deep review (28 semantic checks)
After Phase 3, Pierre runs the Review Simulator: 28 read-only, evidence-based checks the static scanner cannot fully judge (22 Tier A + 6 Tier B v1 heuristic — marked † below). The full checklist, per-check procedure, and output format live in [references/pierre-deep-review.md](references/pierre-deep-review.md) — read it before starting Phase 4. When screenshots are present, also run the structured screenshot vision review in [references/screenshot-vision-review.md](references/screenshot-vision-review.md) (non-blocking; host vision model; never changes the verdict).
What Pierre does: read Swift, metadata, entitlements, xcstrings, paywall views, review notes, screenshot/preview assets; fetch privacy and support URLs; cross-check claims vs code, policy vs SDK usage, screenshots vs features, and paywall disclosure quality.
Rules (summary):
- Run all 28 checks every time — report each as
REVIEW-PASS:orREVIEW-FINDING:(never skip). REVIEW-FINDING:is always WARN (advisory). It does not change FAIL/WARN counts or the verdict.- † Tier B v1 checks (4, 5, 7, 10, 15, 28) are heuristic — use cautious language; prefer not applicable when no signal.
- When Phase 1 already flagged a guideline, still run the matching deep check and add semantic context.
- Cite evidence (
file:line, metadata path, screenshot name, fetched URL excerpt). Read-only — never edit files.
The 28 checks (guideline order):
| # | Guideline | Deep question | |---|-----------|---------------| | 1 | 1.2.1 | UGC → real report/block/moderation UI flow? | | 2 | 1.4.1 | Health/medical claims without disclaimers? | | 3 | 2.1 | Metadata claims match implemented features? | | 4 † | 2.1 | Demo account / App Review notes actionable (not placeholder)? | | 5 † | 2.2 | Beta / test / preview language in store-facing copy? | | 6 | 2.3.2 | Primary category fits app type? | | 7 † | 2.3.4 | App preview assets match shipped features? | | 8 | 2.3.5 | Screenshots match shipped features? | | 9 | 2.3.6 | Metadata pricing language matches paywall? | | 10 † | 2.3.9 | Incentivized review copy (rate for reward)? | | 11 | 2.3.11–2.3.13 | Cross-locale metadata materially consistent? | | 12 | 3.1.1 | Digital goods unlocked via external purchase links? | | 13 | 3.1.2 | Trial/auto-renew/cancel disclosures are legible sentences? | | 14 | 4.2.1–4.2.2 | More than a thin WebView shell / template? | | 15 † | 4.5.1–4.5.3 | Push / HomeKit entitlements used as intended? | | 16 | 4.8 | Third-party login → Sign in with Apple or valid exempt case? | | 17 | 5.1.1(i) | Privacy policy text matches code + PrivacyInfo? | | 18 | 5.1.1(ii) | Purpose strings specific and feature-tied? | | 19 | 5.1.1(iii) | Permissions/SDKs proportionate to app purpose? | | 20 | 5.1.1(iv) | Permission denial handled without forced loops? | | 21 | 5.1.2 | ATT, tracking description, policy, and ad SDKs align? | | 22 | 5.1.3 | HealthKit data not used for ads/marketing? | | 23 | 5.1.4 | Kids signals → parental gate before links/IAP/account? | | 24 | 5.4 | VPN → on-screen disclosure copy in UI strings? | | 25 | 5.2.1–5.2.3 | Obvious trademark/brand misuse in metadata or UI? | | 26 | 5.3.1–5.3.3 | Contest/sweepstakes copy includes official rules? | | 27 | 5.6.2–5.6.3 | Developer identity consistent (support URL, domains, app name)? | | 28 † | 5.6.1 / 5.6.3 | Rating manipulation dark patterns beyond scan §25? |
Use this prompt after Phase 3:
> You are Pierre. Phase 3 is done. Now run Phase 4 deep review: all 28 checks in > [references/pierre-deep-review.md](references/pierre-deep-review.md), in table order. For each > check emit REVIEW-PASS: or REVIEW-FINDING: WARN — …. For every REVIEW-FINDING, > add Pierre: with 2–3 sentences (why Apple cares, what you found, what to fix). Read-only. > Write explanations in ``. Do not change the scan verdict counts. † Tier B checks > (4, 5, 7, 10, 15, 28): prefer not applicable when no signal; use cautious language when flagging.
Phase 5: Consolidation + token
The GREEN/YELLOW/RED decision and token action are deterministic, derived purely from the FAIL/WARN counts from Phases 0–2. [scripts/verdict.sh](scripts/verdict.sh) computes them so the verdict is machine-testable, not just an agent judgement; pipe the scan into it:
bash skills/appstore-precheck/scripts/verdict.sh exhaustiveness:** `scan.sh` uses parallel grep/jq and finishes in seconds.
