Anthropic Promotes New Claude Model With Stronger Coding and Agentic Capabilities

·1 views

Anthropic staff members Thariq Shihipar and Cat Wu joined a roundtable hosted by Datasette founder Simon Willison to showcase the company's latest Claude model, referred to as Fable. The team highlighted significant improvements in agentic coding, claiming the model handles 50% more pull requests and can write its own test scripts to verify its output. Fable can operate autonomously for longer periods, delegate tasks to subagents, process visual data from images and graphs, and be monitored or controlled remotely via a separate device. A live demonstration saw the model independently configure a Microsoft Teams account, add contacts, draft a welcome message, and contact IT administrators — all within 30 minutes. Anthropic staff also shared personal use cases, including building a 2D fighting game and developing a mountain-climbing route planner, illustrating the model's versatility beyond professional tasks.

Developer tool fimod aims to replace repetitive shell scripts in CI pipelines

A developer has published fimod, a lightweight command-line tool designed to handle small data transformation tasks in CI pipelines without resorting to ad-hoc Python snippets or complex shell scripting. The tool supports reading and writing JSON, YAML, and CSV formats, and accepts Python-like expressions to extract, reshape, or validate structured data. Among its built-in features are direct HTTPS URL fetching, regex helpers with named capture groups, dot-path access for nested fields, and SHA-256 hashing for data anonymization. The developer positions fimod not as a replacement for established tools like jq or yq, but as a reusable, portable utility for routine data-shaping tasks shared across repositories. The project is open source and available on GitHub under the handle pytgaen.

BuyWhere MCP Server Lets Shoppers Compare Prices Across 9 Countries in One Query

A developer tool called the BuyWhere MCP server enables real-time cross-border product price comparisons across nine countries and 11 million products through a single function call. The tool exposes a unified search interface that returns merchant names, prices, currencies, and product URLs from multiple marketplaces simultaneously. A task that previously required 15–20 minutes of manual browsing across platforms like Shopee, Lazada, and Amazon can now be completed in under three seconds. The server is compatible with popular AI development environments including Claude Desktop, Cursor, and VS Code, and can also be called via Python scripts. It eliminates the need to build separate API clients for each marketplace, making it particularly useful for developers integrating price comparison into AI agents or shopping tools.

Coolify Offers Self-Hosted PaaS Alternative to Vercel and Heroku at a Fraction of the Cost

Coolify is an open-source, self-hosted platform-as-a-service that lets developers deploy apps via Git push to their own servers, with automatic TLS certificates handled through Traefik and Let's Encrypt. It supports over 280 one-click services including databases and analytics, and works with build tools like Nixpacks, Dockerfile, and Docker Compose. The platform reached stable release with v4.0.0 in April 2026, adding features like Railpack support and audit logging in v4.1 the following month. A comparable Next.js app with Postgres and Redis that costs roughly $1,200 per year on Heroku can run on a Coolify-managed VPS for around €145 annually. However, unlike managed SaaS platforms, Coolify shifts operational responsibilities — including scaling, security patching, and uptime — entirely onto the user.

Lock In App Uses Friction-Based Blocking to Help Users Reclaim Focus Time

A productivity app called Lock In aims to address what its creators describe as 'time blindness' — the gap between intending to work and actually doing so. Unlike conventional focus apps that hard-block distractions, Lock In introduces a hold-to-unlock mechanism requiring users to press and hold a button for 3 to 10 seconds before accessing blocked apps. This brief pause is designed to engage the rational brain and prompt a conscious choice, rather than allowing reflexive phone use. Users can customize which app categories to block per session, while Android users can enable a whitelist mode that restricts everything except selected productive apps. The app's core features are available entirely free, positioning it against paid competitors such as Opal and Freedom that charge up to $100 per year.
