OWASP LLM Top 10 in Production: How I Audited My TypeScript Agent Pipeline Against All 10 Risks — and What I Found

Running the OWASP LLM Top 10 as a real audit is a completely different experience than reading it as a checklist. I ran it against my TypeScript agent stack with system prompts, MCP tools, and Cline — and the findings were uncomfortable.

Cline in VS Code: I used it two weeks on a TypeScript project and this survived

Two weeks using Cline as an autonomous coding agent on a TypeScript project. What tasks I delegated, where it screwed up, how it compares to Claude Code, and which workflows I'd never hand over to it. Architecture-grade analysis, not hype.

Functional Programming in TypeScript: What Survives Outside Pretty Examples

Functors, monads, and pipe() can look pristine in small examples, but real Next.js flows with Server Actions and Prisma expose readability, bundle, and onboarding costs worth measuring before adopting the full pattern.

Mutex deadlocks in production: the patterns I found in my codebase and how I diagnosed them

Three deadlocks in production, all with the same face: the service stopped responding — no error, no panic, no log. What I found while diagnosing them changed how I think about lock design in async Rust.

Kimi K2.6 vs Claude vs GPT-5.5: I ran it against my real coding cases and the numbers surprised me

The hype says Kimi K2.6 beat Claude and GPT-5.5 at coding. I ran it against my own codebase — not cherry-picked HumanEval — and what I found changes the question you should actually be asking.

I tried to reproduce the OpenClaw case in Claude Code: my result contradicts the viral post

The HN thread claimed Claude Code blocked or redirected billing when OpenClaw appeared in Git history. I built a public repo, a reproducible harness, and ran the matrix. On Claude Code 2.1.126, I did not reproduce the block.

OpenAI on Amazon Bedrock: I simulated the migration from my current stack and the numbers don't add up like the announcement promises

The OpenAI on Amazon Bedrock announcement sounds promising. I simulated moving my real API calls to Bedrock and the cold start numbers, IAM overhead, and actual pricing destroy the value proposition for independent projects. The deal benefits AWS, not the dev.

I Almost Cancelled Claude: I Ran My Own Benchmarks Before Pulling the Trigger

874 points on HN for 'I cancelled Claude'. Before joining the chorus, I ran my own regression cases against real Claude Code logs. The degradation is real — just not where everyone's complaining about it.
