We Tested 55 MCP Servers. Here's What Breaks.
MCP servers are the tools AI agents rely on. We tested 55 of them with mcp-assert, found 20 bugs across 9 servers, and submitted fix PRs. Grafana and Ant Group merged ours. Three days after launch, Ant Group’s visualization team asked us to integrate mcp-assert into their CI. The most common failure: servers throw unhandled exceptions instead of returning isError, leaving agents unable to recover.
agent-lsp: Reliable Code Intelligence for AI Agents via MCP and LSP
I needed AI agents to reliably rename symbols, find references, and check diagnostics without silent failures. The existing MCP-LSP tools were stateless, feature-poor, and untested. So I built agent-lsp: a persistent runtime with 50 tools, 20 provider-agnostic skills, speculative execution, and an audit trail for every AI-driven edit.
Branding a CLI Tool in 4 Days: Mascot, Screencasts, and Visual Identity with AI
Most CLI tools ship with no visual identity beyond a help screen. Here’s how I used AI image generation to create Shelby, a consistent mascot with a locked-down spec, and built a complete brand system - poses, screencasts, color palette, terminal theme - for shelfctl in 4 days.
Artifact-Boundary Productization: Clean OSS/Commercial Separation
The execution boundary determines everything: features that need the system alive belong in the platform (OSS). Features that analyze artifacts after shutdown become the product (commercial). A framework for clean OSS/commercial separation.

Your README is a Landing Page, Not Your Documentation
More features always lead to more sprawl. The longer it goes on, the harder it is to bring back under control. Here’s how to treat your README like a landing page - with hooks, not walls of text.
