Developer builds open ledger tracking AI coding tool pricing and limit changes over time

·1 views

A developer has created an unofficial public repository that logs dated snapshots of pricing, usage limits, and rate limits for AI coding tools including Cursor, GitHub Copilot, and Claude Code. The project was motivated by the fact that vendor pricing pages are updated in place, erasing historical values without any public record of what changed. The ledger records only factual, publicly available figures alongside a source attribution and capture date, and makes no claims about vendor intent. It is not affiliated with any vendor, contains no affiliate links, and treats official vendor pages as the authoritative source. The project is in its early stage, with a daily automated capture feature planned but not yet operational.

Developer builds open-source tool to verify and sign AI skill packages

A developer has released Skillerr, an open-source CLI and protocol designed to add cryptographic verification to AI skill packages used by agents in tools like Claude, Cursor, and Codex. The project addresses a growing supply-chain concern: AI skills are typically plain Markdown files with no way to confirm their author, integrity, or whether they have been tampered with. Skillerr assigns each packaged skill a SHA-256 hash and structured contract detailing its permissions, inputs, and outputs, and rejects execution if any file has been altered after packaging. Authors can optionally sign their skills and anchor a package digest in Sigstore's public transparency log for independent verification. The tool is available on GitHub and the developer is actively inviting the community to test it for security vulnerabilities.

Developers Over-Engineered AI Agents but Left Their Own Workflow Unstructured

A software engineering analysis argues that developers have built extensive tooling to keep AI coding agents on track — including linters, CI pipelines, and rules files — but have applied almost no equivalent structure to managing their own work across multiple tasks. The piece distinguishes two distinct loops: an execution loop focused on completing a single task correctly, and an orientation loop concerned with maintaining a shared, accurate picture of all ongoing work. Most existing tools address only the execution loop, leaving the orientation loop to informal methods like manually updated markdown files. Research from ETH Zurich, cited in the article, found that AGENTS.md context files offer minimal benefit to agents and can even slightly reduce performance, while costing over 20% more in context overhead. The author calls for 'harness engineering' to be turned inward, applying the same disciplined, automated accountability to the human operator's workflow that is already standard practice for AI agents.

stoneChat Brings AI Chat to Windows XP and Internet Explorer 6

A developer has released stoneChat, a locally hosted LLM web chat client designed to run on Windows XP-era hardware using Internet Explorer 6. The project uses a PHP backend to handle chat requests, with stunnel added to enable HTTPS connectivity for modern AI API endpoints. It supports OpenAI-compatible APIs, and each model can be individually configured with its own endpoint, API key, token limit, and streaming settings via an INI file. User management, language preferences, and keyboard behavior are also controlled through the same configuration file. The application requires PHP 5.4 or newer on Windows and is launched via a RUN.cmd script, with source code available on GitHub under the WTFPL license.

Developer Builds Free Serverless Bluesky AI Bot Using GitHub Actions and Gemini API

A developer created an automated Bluesky posting bot to maintain consistent social media presence without consuming development time. The bot runs entirely on free infrastructure, using GitHub Actions for scheduled execution, Google's Gemini API for AI-generated content, and Bluesky's official API for publishing. Credentials are stored securely as GitHub Secrets, eliminating the need for a paid VPS or cloud service. Bot behavior, including posting schedule, topics, and tone, is controlled through a configuration file rather than hardcoded values. The completed project has been published publicly on GitHub for others to reuse and adapt.
