webclaw is an open-source tool that converts websites into clean Markdown, JSON, and LLM-ready context, available as a CLI, MCP server, REST API, and SDKs for AI agents and RAG pipelines.
TSON is a schema system and JSON superset with immutable, hash-pinned schemas whose definitions are themselves data. It offers a compact schema grammar and a working Java implementation.
The author built a service that exposes Google Patents data as structured JSON over MCP, letting AI agents query patent claims, citations, family graphs, and summaries across many patent offices, with pay-per-event pricing.
Sugiere pedirle a CLAUDE o CODEX que genere la arquitectura completa de una app en una sola página HTML y un archivo JSON, permitiendo visualizarla y que otro agente la entienda. Incluye un prompt de ejemplo.
condense-json 1.1 adds structural replacements and merge operations for objects, plus property-based round-trip tests using Hypothesis.
This article explains how JSON serialization in JavaScript silently changes data: large integers lose precision, undefined properties disappear, Dates become strings, and NaN becomes null. It traces the history of JSON and argues that developers should define explicit wire formats to avoid accidental data contracts.
Simon Willison announces the 1.0 release of condense-json, a Python library that condenses JSON by replacing repeated substrings with compact references, saving space in SQLite logs for LLM.
A study shows that when LLMs are asked to output in JSON format, their answer diversity collapses significantly compared to plain chat, with modal answers becoming more common and distinctive models losing half their uniqueness.
libpdjson5 is a public domain C library for parsing JSON, JSON5, and JSON5E with full Unicode support, minimal memory footprint, and a streaming API. It is a fork of pdjson with various improvements including JSON5E support.
The article shares production learnings for reliably generating structured JSON output from LLMs, covering methods like JSON mode, schema validation, and retry loops, achieving 99.5% validity.
一个 Open WebUI 工具，使用 python-docx 将模型产出的 Markdown（含 YAML 头）或 JSON 规范直接生成为原生、可编辑的 Word (.docx) 文档，支持多种模板和样式。
A developer discusses building an execution validator for AI agent-generated graphs where nodes interact via inputs and references, seeking advice between using test accounts or graph traversal for validation.
Microsoft's developer advocate tests whether agents work better with JSON payloads or conventional CLI arguments, finding that flat CLI args actually perform better in terms of success rate, token efficiency, and latency.
A tool that extracts tables from pasted HTML, rich text, or plain text and exports them to HTML, Markdown, CSV, TSV, or JSON, with added Wikipedia search and automatic table import.
The paper presents simdjson, the first validating JSON parser capable of processing gigabytes per second on a single core using SIMD instructions, achieving substantial speedups over existing parsers like RapidJSON.
C++26's #embed and static reflection, combined with the simdjson library, allow JSON parsing at compile time, turning configuration files into compile-time constants with no runtime overhead.
The article argues that disallowing trailing separators (like commas) in programming languages and data formats makes code editing more error-prone and less consistent, and advocates for language designs that permit trailing separators for better developer experience.
A fast, zero-copy C11 library for reading and writing the Transit data format with SIMD acceleration, supporting JSON, JSON-Verbose, and MessagePack wire formats via a single codec-agnostic engine.
Paint By JSON is a tool that lets designers populate mockups with real API data as easily as using lorem ipsum placeholder text.
OmniParse is a local platform that ingests and parses unstructured data (documents, images, video, audio, web) into structured JSON optimized for LLM applications like RAG and fine-tuning.
