Have your agent record video demos of its work with shot-scraper video

shot-scraper 1.10 introduces a new video command that reads a YAML storyboard file and uses Playwright to record browser-based video demos of web applications. The feature is designed to let coding agents autonomously produce demo videos of their own work. The storyboard YAML supports scenes, clicks, fills, waits, JavaScript injection, and server startup — all validated via Pydantic. The implementation was written by GPT-5.5 xhigh in Codex Desktop, unblocked by playwright-python 1.61.0 which fixed a video width limitation. The author highlights a pattern where rich --help output enables agents to use a tool without additional documentation.

Context Engineering for RAG : The Four Typed Inputs Behind Every RAG Answer

Context engineering — the discipline of assembling everything that lands in an LLM's context window — is applied to a single-document RAG pipeline built from four typed bricks: document parsing, question parsing, retrieval, and generation. Each brick emits typed outputs (Pydantic models, DataFrames, audit dicts) that converge on one LLM call. The system prompt is fixed for caching, retrieved lines are filtered to a few thousand tokens, and doc-level metadata is serialized as compact JSON via a PromptContext aggregator. The term 'context engineering' was coined by Tobi Lütke and endorsed by Andrej Karpathy in June 2025. Practical implications include cheaper cached prompts, auditable per-call context reconstruction from persisted brick outputs, and a stable aggregator signature that can absorb corpus-context and conversation-context layers without breaking existing brick signatures.
