JSON schemas auto-generate UIs for cross-platform MCP server settings
A new approach leverages JSON schemas to automatically generate user interfaces for configuring Multiplatform Settings for MCP Servers. This method allows a single codebase using Compose Multiplatform to create native s…
-
AI agents struggle with semantic tool selection despite schema validation
A developer found that strict schema validation for AI agent tool calls did not significantly reduce failures, as most errors were semantic rather than structural. The majority of issues involved the agent selecting the…
-
AI agents can cut token waste by stripping tool schema cruft
Developers can significantly reduce token waste in AI agent tool schemas by removing unnecessary fields like "title", "$schema", and "additionalProperties". These fields, often comprising up to 20% of a schema's size, d…
-
AI agents now autonomously use decades-old APIs as 'tools'
The concept of an AI 'tool' refers to a specific, atomic capability that an AI agent can autonomously invoke. These tools, often defined by a JSON schema for parameters and outputs, are not new in themselves, as APIs ha…

LLM accuracy suffers when forced to output JSON directly
Forcing large language models (LLMs) to output structured data like JSON directly can significantly reduce their accuracy. This is because LLMs generate text token by token, and forcing an immediate, empty output robs t…
-
LLMs replace CSS selectors for resilient web scraping
A new method for web scraping uses Large Language Models (LLMs) to extract data, offering a more resilient approach than traditional CSS selectors. This LLM-powered technique focuses on the semantic meaning of content r…

Claude's tool use ensures reliable JSON output for developers
A developer guide demonstrates how to reliably extract structured data from Anthropic's Claude models by leveraging their tool-use feature. Instead of directly prompting for JSON, the technique involves defining a fake …
-
LLM output validation and efficiency strategies detailed
Several articles discuss robust methods for handling Large Language Model (LLM) outputs in production environments, emphasizing the need for structured validation beyond simple JSON formatting. Techniques like Pydantic …
