A Cloudflare Worker that serves the documentation site from R2 storage. Implements clean URL routing, markdown content negotiation via Accept header, in-memory caching with caches.default, search API integration with Pagefind, MCP protocol endpoints, and custom 404 handling. The caching logic is robust, using cache keys based on the full URL including query strings, and respects cache-control headers. This is a self-contained, reusable pattern for serving statically generated sites with advanced features.

A shared Python module used by full and incremental translation workflows. It handles locale selection, source document counting, shard expansion, and output generation for translation manifests. The module uses dataclasses for typed configuration, environment variable fallbacks, and writes structured outputs to GITHUB_OUTPUT and GITHUB_STEP_SUMMARY. It is well-documented with docstrings and examples, and is designed to be reusable across different workflow entry points.

A security-hardened code review tool that bundles repository changes and submits them to AI engines (codex, claude, pi) for review. It supports local, commit, and branch modes, with parallel test execution, secret detection, and safe environment isolation. The script includes a complex secret_text_risk function that patterns credentials across many languages and contexts. The output is structured JSON with validated review patches. This is a standalone, reusable tool that could be adapted for any repository requiring AI-assisted code review.
