  • A skill that was too long to be read carefully

    Note2 min read

    A two-thousand-word document describing this application’s architecture, which produced worse output than no document. A long document produces confident output that follows some of it, which is worse…

  • Reusable skills and agent definitions, and what they are actually for

    Deep dive18 min read

    turkerdev/ai-skills and turkerdev/ai-agents, and eighteen months of retyping the same instructions. Context is per-session and knowledge is not.

    Note2 min read

    A document describing this codebase’s conventions, read by a tool and by people, kept in the repository. The file is the single most effective thing we have done…

  • Acceptance rate, edit distance, and what neither measures

    Note2 min read

    Two metrics that are available, neither of which answers the question anybody is asking. A high acceptance rate is compatible with a tool that produces plausible code and…

  • A tool that does not know this codebase’s conventions

    Note2 min read

    Suggestions that are idiomatic for the language and wrong for this application, which is the most expensive kind of wrong. Both suggestions are what most PHP looks like,…
