Cursor MCP Tool Boundary

The xclog, xcsym, and xcprof examples below are reference syntax, not executable commands for Cursor. Map each subcommand to the same-named MCP tool—for example, xclog launch to axiom_xclog_launch, xcsym crash to axiom_xcsym_crash, and xcprof record to axiom_xcprof_record—and preserve its arguments as structured fields. Do not run a bare helper binary. If a required MCP tool is unavailable, stop and report that the Axiom MCP integration is missing; do not fall back to a same-named executable.

Shipping & App Store

You MUST use this skill when preparing to submit ANY app, handling App Store rejections, or working on release workflow.

Cursor Subagent Routing

Delegate to the appropriate Cursor subagent when this router calls for a specialized auditor.

When to Use

Use this skill when you encounter:

• Preparing an app for App Store submission
• App Store rejection (any guideline)
• Metadata requirements (screenshots, descriptions, keywords)
• Privacy manifest and nutrition label questions
• Age rating and content classification
• Export compliance and encryption declarations
• EU DSA trader status
• Account deletion or Sign in with Apple requirements
• Build upload and processing issues
• App Review appeals
• WWDC25/WWDC26 App Store Connect changes
• First-time submission workflow

Quick Reference

Routing Logic

1. Pre-Submission Preparation → app-store-submission

Triggers:

• "How do I submit my app?"
• "What do I need before submitting?"
• Preparing for first submission
• Pre-flight checklist needed
• Screenshot requirements
• Metadata completeness check
• Encryption compliance questions
• Accessibility Nutrition Labels
• Privacy manifest requirements for submission

Why app-store-submission: Discipline skill with 8 anti-patterns, decision trees, and pressure scenarios. Prevents the mistakes that cause 90% of rejections.

Reference: skills/app-store-submission.md

2. Metadata, Guidelines, and API Reference → app-store-ref

Triggers:

• "What fields are required in App Store Connect?"
• "What's the max length for app description?"
• Specific guideline number lookup
• Privacy manifest schema details
• Age rating tiers and questionnaire
• IAP submission metadata
• EU DSA compliance details
• Build upload methods
• WWDC25 and WWDC26 changes to App Store Connect

Why app-store-ref: 11-part reference covering every metadata field, guideline, and compliance requirement with exact specifications.

Reference: skills/app-store-ref.md

3. Rejection Troubleshooting → app-store-diag

Triggers:

• "My app was rejected"
• "Guideline 2.1 rejection"
• "Binary was rejected"
• Guideline 4.2 or 4.3 rejection (app too simple, web wrapper, spam, duplicate)
• Guideline 1.x rejection (objectionable content, UGC moderation, Kids category)
• How to respond to a rejection
• Writing an appeal
• Understanding rejection messages
• Third or repeated rejection
• Resolution Center communication

Why app-store-diag: 9 diagnostic patterns mapping rejection types to root causes and fixes, including subjective rejections (4.2/4.3, 1.x). Includes appeal writing guidance and crisis scenario for repeated rejections.

Reference: skills/app-store-diag.md

4. Privacy & Security Compliance → security-privacy-scanner (Agent)

Triggers:

• "Scan my code for privacy issues before submission"
• Hardcoded API keys or secrets
• Missing privacy manifest
• Required Reason API declarations
• ATS violations

Why security-privacy-scanner: Autonomous agent that scans for security vulnerabilities and privacy compliance issues that cause rejections.

Invoke: Delegate to the security-privacy-scanner subagent or /axiom-audit security

5. IAP Review Issues → iap-auditor (Agent)

Triggers:

• IAP rejected or not working
• Missing transaction.finish()
• Missing restore purchases
• Subscription tracking issues

Why iap-auditor: Scans IAP code for the patterns that cause StoreKit rejections.

Invoke: Delegate to the iap-auditor subagent

6. Screenshot Validation → screenshot-validator (Agent)

Triggers:

• "Check my App Store screenshots"
• "Are my screenshots the right dimensions?"
• "Validate screenshots before submission"
• "Review my marketing screenshots"
• Screenshot content or dimension questions

Why screenshot-validator: Multimodal agent that visually inspects each screenshot for placeholder text, wrong dimensions, debug artifacts, broken UI, and competitor references. Catches issues that manual review misses.

Invoke: Delegate to the screenshot-validator subagent or /axiom-audit screenshots

7. Programmatic ASC Access → asc-mcp

Triggers:

• "Automate App Store Connect"
• "Submit build programmatically"
• "Manage TestFlight from Claude"
• "Respond to reviews via API"
• "Set up asc-mcp"
• "Distribute to TestFlight groups via MCP"
• "Create a new version without opening ASC"

Why asc-mcp: Workflow-focused skill teaching Claude to use asc-mcp MCP tools for release pipelines, TestFlight distribution, review management, and feedback triage — all without leaving Claude Code.

Reference: skills/asc-mcp.md

8. Post-Submission Monitoring → app-store-connect-ref

Triggers:

• "How do I view crash data in App Store Connect?"
• "Where are my TestFlight crash reports?"
• "How do I read ASC metrics dashboards?"
• Post-release crash investigation
• Downloading crash logs from ASC

Why app-store-connect-ref: ASC navigation for crash dashboards, TestFlight feedback, performance metrics, and data export workflows.

Reference: skills/app-store-connect-ref.md

9. Beta Crash Triage → testflight-triage

Triggers:

• Beta tester reports a crash
• Crash appears in Organizer or App Store Connect
• Crash logs need symbolication
• Post-release crash investigation (single file or Organizer)

Why testflight-triage: Systematic crash triage from symbolication through root cause analysis. Uses xcsym as the first step (parse → discover dSYMs → symbolicate → categorize with pattern_tag → emit structured JSON).

Reference: skills/testflight-triage.md. For the xcsym subcommand/exit-code reference, see axiom-tools (skills/xcsym-ref.md). For the one-call agent workflow, /axiom-analyze-crash.

10a. Production Corpus Triage → production-triage / triage-analyzer

Triggers:

• "Triage my Sentry crashes"
• "What are the top crash families in production?"
• "Show me which issues to fix first from App Store Connect"
• Multiple grouped issues from an aggregator (Sentry, ASC) — dozens of issues, not a single file
• "Which of these crashes are real bugs vs noise?"
• Corpus-level hang triage ("Are my ANR reports real blocks?")

Why production-triage: Corpus-level triage requires fetching from an aggregator, classifying each issue, noise-flagging suspension false-positives, and clustering into root-cause families. testflight-triage covers the Organizer path — single files and the local on-disk .xccrashpoint corpus; production-triage covers the aggregator path (Sentry / ASC grouped issues).

Reference: skills/production-triage.md (fetch + NormalizedReport schema + flag-never-hide rule). Agent: triage-analyzer or /axiom-triage sentry / /axiom-triage asc.

10. Distribution Signing Issues → code-signing / code-signing-diag

Triggers:

• ITMS-90035 Invalid Signature on upload
• ITMS-90161 Invalid Provisioning Profile
• "No signing certificate found" when archiving
• Certificate expired before submission
• Archive succeeds but export/upload fails
• Profile doesn't match bundle ID
• Entitlement mismatch on upload

Why code-signing: Distribution signing errors are the #1 cause of upload failures. Diagnosing with CLI tools takes 5 minutes. code-signing-diag has 6 decision trees mapping ITMS errors to root causes.

Reference: See axiom-security (skills/code-signing-diag.md) (troubleshooting) or See axiom-security (skills/code-signing.md) (setup)

11. App Clips → app-clips

Triggers:

• Adding an App Clip target, or choosing an invocation method
• "What's the App Clip size limit?" / build exceeds maximum size
• Associated domains / AASA for App Clip links
• App Store Connect default and advanced launch experiences
• Handing App Clip data off to the full app on upgrade
• "My App Clip link does nothing"

Why app-clips: App Clips ship embedded in the full app and live under tight size (10/15/100 MB), entitlement, and capability limits. The discipline covers the size tiers, entitlements, AASA, and data handoff; the reference has the tables.

Reference: skills/app-clips.md, skills/app-clips-ref.md

Anti-Rationalization

External Resources

Cloud Claude migration (claude-api skill, ships outside Axiom) — mandatory before shipping any Claude model-ID change. Opus 4.7 removed temperature, top_p, top_k, and prefill from the Messages API; code that built successfully on 4.6 returns HTTP 400 at runtime. An App Store update that ships this regression is an expedited-review situation. The claude-api skill automates the migration (model ID swap, sampling-param removal, prefill replacement) and enforces prompt caching from day one. Treat it as part of your pre-flight checklist, not a side reference.

When NOT to Use (Conflict Resolution)

Do NOT use axiom-shipping for these — use the correct skill instead:

axiom-shipping is for the submission workflow, not code implementation:

• Preparing metadata and compliance → axiom-shipping
• Writing the actual code → domain-specific skill (axiom-build, axiom-data, etc.)
• App was rejected → axiom-shipping
• Code changes to fix rejection → domain-specific skill, then back to axiom-shipping to verify
