  • How to Be More Ambitious: A Tutorial for Humans with Models: Felix Rieseberg argues AI capabilities grow unevenly, so users should aim higher, framing ambition as speed, altitude, depth, and range. Advice: target the outcome beyond the task, use the raw data and methods top professionals use, and have the model do what other fields' experts do rather than role-play them. Related: AI. Keywords: ambition, AI workflows, prompting, agents, productivity

  • Portal by Spotify Cut My Claude Code Token Usage by 90%: Spotify routes I/O-heavy grunt work to cheap "modes" (Gemini 2.5 Flash) instead of Claude — a PreToolUse hook blocks reads of files over a line threshold and redirects them to a "bulk-reader" mode, plus a "code-writer" mode for boilerplate, preserving Claude's tokens for reasoning. Related: Tools, AI. Keywords: Claude Code, hooks, model routing, PreToolUse, token cost, Gemini, skills

  • Bhoonidhi MCP Server: An MCP (Model Context Protocol) server that lets AI agents search and download ISRO's Bhoonidhi satellite imagery archive using natural language queries — resolving locations and satellite names automatically and reporting scene availability (Ready, Archived, On Order, Priced) before download. Related: Remote_Sensing, Data. Keywords: MCP, Claude Code, ISRO, India, satellite imagery, remote sensing, AI agent

  • 9 Verified Tools to Stop Burning Claude Tokens Unnecessarily: Skills, hooks and services to help reduce token use. Related: Tools. Keywords: Claude Code, skills, hooks, productivity, tokens, cost optimization

  • Ponytail: A Claude Code skill that enforces a "lazy senior developer" philosophy — a decision ladder that prioritizes using existing solutions (stdlib, native features, installed dependencies) before writing new code, demonstrating ~54% reduction in lines of code and ~20% cost savings. Related: AI. Keywords: Claude Code, skills, agents, productivity, best practices, code generation

  • GeoSQL: A Claude/Codex skill for data scientists and analysts working with geospatial data on PostGIS, BigQuery, Snowflake, and Wherobots — enables spatial SQL analysis through an AI agent with real-time map visualization for previewing and validating geographic query results locally. Related: SQL, AI, Data. Keywords: Claude Code, SQL, geospatial, spatial SQL, PostGIS, BigQuery, Snowflake, agents, skills

  • Matt Pocock's Claude Code Skills: A collection of reusable AI-powered agent skills for engineers covering tasks like test-driven development, code refactoring, architectural improvements, and project planning — from the creator's personal development toolkit. Related: AI. Keywords: Claude Code, skills, agents, TDD, refactoring, TypeScript, productivity

  • Karpathy-Inspired Claude Code Guidelines: A single CLAUDE.md file derived from Andrej Karpathy's observations on LLM coding pitfalls, enforcing four principles: Think Before Coding, Simplicity First, Surgical Changes, and Goal-Driven Execution. Related: AI. Keywords: Claude Code, CLAUDE.md, guidelines, prompting, best practices, Karpathy

  • Geospatial Skills for Claude Code: A catalog of installable geospatial tools and capabilities designed for coding agents, covering raster/vector processing, satellite data, and interactive visualization. Related: AI, Remote_Sensing, Data. Keywords: Claude Code, geospatial, agents, skills, raster, vector, satellite

  • Clicky: An open-source macOS menu bar app that uses Claude as a screen-aware AI tutor, allowing users to point at UI elements and get contextual explanations. Designed to be set up via Claude Code. Related: AI. Keywords: Claude Code, Claude, macOS, AI tutor, screen awareness, learning, education

  • Humanizer SKILL: A Claude skill file that identifies and removes 25+ patterns of AI-generated text to make writing sound more natural and human, including inflated language, promotional tone, and stylistic tics. Related: AI. Keywords: Claude, Claude Code, skills, writing, AI text, prompting

  • Stop Slop: A Claude skill file designed to identify and remove telltale patterns of AI-generated writing from prose, helping improve authenticity and readability. Related: AI. Keywords: Claude, Claude Code, skills, writing, AI text, prompting

  • Coding Agents for Data Analysis: Workshop guide by Simon Willison on using coding agents (Claude Code, OpenAI Codex) for data journalism tasks — covers database queries, data cleaning, visualization, and web scraping using Python, SQLite, and Datasette.
