python-3-brutal-audit

python-3-brutal-audit is a cursor rule for Cursor from beettlle/pi-spine. It costs 0 tokens per session (3,235 once invoked), scanned A, original, MIT.

A structured review process for Python projects that checks the codebase in phases against stated development and anti-pattern rules.

In plain words
What is it for?
Use it to run a full or selected audit, check whether a development phase is complete, and report verified problems in the codebase.
Why use it?
It helps find poor design, incomplete work, and low-quality code before they become harder to fix.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 3,235 The whole file, excluding the scripts and references it only reads on demand.

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

python-3-brutal-audit scanned grade A with 1 finding 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 3d 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.

Python Brutal Audit Workflow

This rule defines the workflow for conducting a "Brutal Audit" of the Python codebase.

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

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

  1. Tool Usage: Use grep and codebase_search to verify the checks below. Do not just "look" at files; verify them.
  2. Reporting: Output the results in the format specified at the end.
  3. 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: 2.1 (Updated for Python 3.13+, asyncio, pytest)

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/python-3-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

Tool: Use grep to verify before detailed audit.


🔵 PRE-CODE GENERATION: Chain-of-Thought Checkpoints

Before generating code, identify:

  1. Which layer affected (Domain/Data/Presentation)
  2. Similar pattern exists? (Check codebase first)
  3. Framework provides direct API? (Verify docs)
  4. Ghost layer candidate? (>80% delegation check)

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.

python-3-brutal-audit is a cursor rule published in the GitHub repository beettlle/pi-spine (3 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,235 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
