shadowsky: Command for Claude Code

.claude/commands/qa-ios-build.md

qa-ios-build is a command for Claude Code from dmoskov/shadowsky. It costs 13 tokens per session (403 once invoked), scanned A, original, MIT.

A command that builds an iOS app and reports whether compilation succeeded, including errors, warnings, file locations, and suggested fixes when available.

In plain words
What is it for?
Use it to verify an Expo iOS app, investigate compiler errors, group related failures, and check warnings.
Why use it?
It provides a repeatable check for build failures instead of relying on a developer to inspect long build output manually.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the TodoWrite tool.

This is dmoskov/shadowsky's own configuration. It tells Claude Code how to work on shadowsky itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shadowsky configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/moskov/Code/BSKY/mobile.

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.

Security

Grade A, and why

qa-ios-build 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

iOS Build Verification

Build the iOS app and report success or failure.

Instructions

  1. Run the iOS build from the mobile directory:

    cd /Users/moskov/Code/BSKY/mobile && npx expo run:ios --no-install
    

    Use a 5-minute timeout since builds can be slow.

  2. Parse the build output:

    • Look for Build Succeeded or Build Failed
    • Count errors and warnings
    • For errors, report the file path, line number, and error message
    • For warnings, note them but focus on errors first
  3. If the build fails:

    • Read the failing file(s) to understand the error context
    • Suggest a fix for each error
    • Group related errors (e.g., multiple errors from a single bad import)
  4. Report results:

    Build: PASS/FAIL
    Errors: N
    Warnings: N
    
    [If failed, list each error with file:line and suggested fix]
    

Common Build Errors

Error Cause Fix
cannot find type 'X' in scope Missing import or access control Add import or mark type as public
'X' is only available in iOS N.0 or newer API too new for deployment target (15.1) Use older API or add availability check
use of unresolved identifier Typo or missing import Check spelling, add import
expression type 'X' is ambiguous SwiftUI view builder inference failure Add explicit type annotations
missing argument for parameter Struct initializer changed Update call sites to match new signature

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.
