Developer-Tools

I have a code agent—Claude Code—that interacts with Linear, my task management tool, about 800 times a month: listing tasks, creating issues, changing states, leaving comments. I reviewed 165 of its sessions and counted more than 500 errors and over 370 retries. None of these were caused by issues in Linear’s API. All were interface errors: the agent communicated with the command line, and the command line didn’t understand it. ...

My CLI’s most frequent user isn’t me lql is a Rust CLI for managing Linear issues. I wrote it because none of the existing alternatives worked for my actual use case: an AI agent that manages issues autonomously. Why I had to write my own CLI Linear’s MCP was the first attempt. The idea is elegant: an MCP server that exposes Linear’s API directly to the agent. In practice, it was slow, unstable, and the agent had to build GraphQL queries from scratch on every call. Each call was an opportunity to invent a field that doesn’t exist. I uninstalled it after two weeks. ...

You ask your AI copilot to capture a window. The copilot writes peek app "Xcode". The tool looks for a window owned by Xcode exactly. It doesn’t find one because the process is named Xcode-16.3. The tool responds with Error: application not found. The copilot, a large language model (LLM) with the memory span of a goldfish, then tries peek app "Xcode-16.3". This time it works—but it’s wasted a conversational turn, input tokens, output tokens, and the patience of the person paying the bill. ...

Yesterday I wrote a commit message with Claude Code. The diff was a one-line change: a typo in a comment. Claude Opus read the diff, thought for two seconds, and generated fix: correct typo in auth comment. That consumed about 800 input tokens and 30 output tokens, at $15 and $75 per million respectively. Cost: a fraction of a cent. But multiply that by 40 commits per day, 250 days per year, across a company with 200 developers using coding agents, and the fraction of a cent becomes thousands of dollars spent on the intellectual equivalent of applying band-aids. ...
