  • definitely a little bit of shameless self promotion but I write about a lot of common harness concepts in the docs of Wingman (https://wingman.actor) - a client agnostic agent harness I've been working on for a while:

    https://docs.wingman.actor/concepts/sessions/

    I think there is still plenty of innovation to be had in the space. Right now everything is still pretty bundled to the file system where getting skills and things to work inside of like a virtual worker requires simulating a virtual file system (usually). I believe even in the latest opencode v2 versions it still requires that a session be bundled to a working directory, I try to avoid (some of) that in Wingman.

  • I like how agent review is a deprecation target. explicitly. Se then a harness matures by getting dumber and cheaper, not smarter.

  • it lists 'Garbage Collection' as one of the 3 components of a harness

    I don't know any harness that solves 'Garbage Collection' in the way described here

    (most harnesses accelerate context pollution and code base drift via instructions they embed into system prompts, tool descriptions and skills)

  • Not saying this is AI-gen but it's very dense and doesn't read like something I could glean info from easily

  • This part seems relevant - they make explicit the difference between their HARNESS.md document and AGENTS.md. It's actually interesting: https://habitat-thinking.github.io/ai-literacy-superpowers/p...

  • Here’s the original article this one is based on: https://martinfowler.com/articles/harness-engineering.html

    And here is the original author on a podcast talking about it: https://open.spotify.com/episode/4FxEdjXldNhoh67KYVmbDu

  • It’s fascinating to live through a the emergence of a new technology and to see people trying to make sense of it as they go.

    I personally think that a lot of the words used around AI, harness, SKILLS, agents, RAG.. are make up words or close to it, words that do not have profound semantics, even though people are trying to, often after the fact, make sense of them.

    It’s just popular words that are different enough that people like to use them to claim a new knowledge, or to market a product.

    But we could use AI tooling instead of harness in the abstract, and it would be better to use more precise terms for more concrete use cases, agent loop, CLI, IDE..

    It was a fun game at a time where papers were competing for attention, but now that it has become a proven technology, I hope we can find more precise and meaningful words.

  • The term harness engineering does not come from Birgitta Boeckeler's article in martinfowler.com. It was first used by Mitchel Hashimoto months earlier in his 'My AI adoption journey' blog post [1], and immediately picked up by OpenAI [2] a week later.

    Also worth noting that this text is not only entirely AI generated, but meant for other agents to read, not us humans.
