- Building an Intern
Building a practical Slack agent required 100k lines of TypeScript and four months of iteration to handle serverless constraints, credential management, and secure tool orchestration.
- Coding sessions in Linear – Changelog
Linear Agent can now write and review code using Claude Code and Codex, enabling end-to-end issue-to-ship workflows from within Linear.
- The evolution of agentic surfaces: building with Claude Managed Agents
Claude Managed Agents decouples model reasoning from code execution to let teams deploy production-grade agents without building custom infrastructure.
- How we cut build times by two-thirds by deleting our CMS
Sentry cut build times from 14 to under 4 minutes by replacing its headless CMS with Astro, Markdown files, and Claude Code skills for content management.
- claude code is not making your product better
Coding agents increase senior engineer output but not product velocity, as the bottleneck is product taste and complexity management, not code production speed.
- Fair Source Software in the AI age
Fair Source licensing remains viable in the AI era by using contract law, not just copyright, to prevent clones from competing, even as AI-generated code challenges traditional open-source enforcement.
- Warden
Warden is a CLI tool that uses Markdown-defined skills to create AI agents that automatically review every pull request for security and correctness issues.
- AI is killing B2B SaaS
AI's ability to let enterprises quickly build fit-for-purpose internal tools is undermining bloated, expensive B2B SaaS products that fail to evolve.
- Context Management and MCP
The article argues that MCP's value is in steering agents with rich context descriptions, that progressive disclosure is counterproductive, and that subagents may better manage context rot.
- Thoughts on Evals – Raindrop Blog
Production monitoring and A/B testing offer more reliable evaluation of AI agents than offline evals, which fail to capture real-world performance.
- MCP, Skills, and Agents
Skills and MCP tools serve different but complementary purposes for coding agent harnesses, and neither replaces the other despite hype cycles claiming otherwise.
- A Year Of Vibes
Armin Ronacher reflects on 2025 as a year of agentic coding tools like Claude Code, which replaced much of his direct programming, and discusses the cultural, technical, and social challenges this shift presents for software engineering.
