Persona: You are a senior Go security engineer. You apply security thinking both when auditing existing code and when writing new code — threats are easier to prevent than to fix.

Transcribe an audio file via OpenAI’s /v1/audio/transcriptions endpoint. Set OPENAI_BASE_URL to use an OpenAI-compatible proxy or local gateway.

Comprehensive guidance for implementing asynchronous Python applications using asyncio, concurrent programming patterns, and async/await for building high-performance, non-blocking systems.

AI-powered logo design with iterative refinement, background removal, and SVG export. \n \n Guides users through discovery (style, ratio, colors) before generating 20 initial logo variations using AI image generation \n Includes batch generation, HTML preview gallery, and iterative feedback loops to refine designs across multiple rounds \n Provides post-processing tools: automatic whitespace cropping, background removal via remove.bg API, and vectorization to SVG format \n Requires three API key

FastAPI best practices and conventions for clean, modern API development. \n \n Use Annotated for all parameter and dependency declarations to maintain type safety, reusability, and compatibility with other contexts \n Declare return types or response models on path operations to enable automatic validation, filtering, serialization, and OpenAPI documentation \n Use async def only when calling async code with await ; default to regular def for blocking operations to avoid event loop blocking \n

Java method extraction refactoring for improved readability and maintainability. \n \n Identifies methods exceeding complexity thresholds (LOC > 15, statements > 10, cyclomatic complexity > 10) and extracts logical code blocks into focused helper methods \n Produces fully compilable Java 17 code with descriptive method names and single-line documentation comments \n Preserves all original functionality while reducing cognitive load and improving testability through smaller, single-responsibility

Modern Python project setup with uv, ruff, and ty for Python 3.11+. \n \n Replaces pip, Poetry, black, flake8, mypy, and pre-commit with faster, simpler alternatives from the Astral team \n Covers new project creation, dependency management via uv add / uv remove , and linting/formatting/type-checking workflows \n Includes migration paths from legacy tooling (requirements.txt, setup.py, flake8+black+isort, mypy/pyright) \n Provides decision tree for single-file scripts (PEP 723), simple projects
