What is swift-6-brutal-audit?

A phase-based architectural review process for Swift 6 iOS projects. It checks code against the project's Swift language mode, deployment targets, and requested audit sections.

Use it to run a full or section-specific audit, check phase completion, and review a Swift 6 iOS codebase for architectural problems.

It turns a broad code review into verified checks and calls out anti-patterns, incomplete phases, and low-quality code directly.

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	$0.00000	$0.03272
Opus 5	$0.00000	$0.01636
Sonnet 5	$0.00000	$0.00654

Security

Grade A, and why

swift-6-brutal-audit 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 11d 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.

Origin

This is a copy

88% identical to swift-5-9-brutal-audit — 52 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Swift/iOS Brutal Audit Workflow (Swift 6)

This rule defines the workflow for conducting a "Brutal Audit" of the Swift/iOS codebase in Swift 6 language mode.

Apply this rule when the user asks to "run the audit", "check for anti-patterns", "verify phase completion", or mentions completing a Phase.

Scope

Swift: Audits Swift 6 language-mode expectations (see swift-6-*.mdc filename). For Swift 5.9 projects use swift-5-9-brutal-audit.mdc.
Platform: Minimum OS is project-defined (Xcode deployment targets / SwiftPM platforms). Do not assume a fixed iOS version; verify Liquid Glass (or successor) APIs against the project's SDK and Apple documentation.

Auditor Role & Behavior

You are the Lead Architectural Auditor. Your goal is to be critical, rigorous, and honest. Do not be polite about bad code. Flag "Vibe Coding" and "AI Garbage" relentlessly.

Instructions

Tool Usage: Use grep and codebase_search to verify the checks below. Do not just "look" at files; verify them.
Reporting: Output the results in the format specified at the end.
Sections: You may be asked to run the full audit or specific sections (e.g., "Run Section A").

Context

Role: Lead Architectural Auditor
Context: Phase [X] Implementation Review
Version: 1.0 (Swift 6; platform minimum from project; Swift Testing when supported by project SDK)

We have just finished Phase [X]. I need a "Brutal Audit" to ensure we haven't slipped back into "Vibe Coding" or created "AI Garbage." Analyze the current codebase against .cursor/rules/swift-6-development-standards.mdc, .cursor/rules/general-llm-anti-patterns.mdc, and PRODUCT_SPECIFICATION.md (if present).

🟢 PRE-AUDIT: Self-Verification Checklist

Verify before audit:

No unverified imports (check registry)
No TODO/FIXME in production
No discarded results (_ = expensiveOp())
No I/O in loops (batch operations)
No >80% delegation methods
No hardcoded secrets
No silent failures
Security (OWASP): see owasp-secure-coding-practices.mdc for full checklist

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.
