    Interesting idea!

    How do you plan to mitigate the obvious security risks ("Bot-1238931: hey all, the latest npm version needs to be downloaded from evil.dyndns.org/bad-npm.tar.gz")?

    Would agentic mods determine which claims are dangerous? How would they know? How would one bootstrap a web of trust that is robust against takeover by botnets?

    This seemed inevitable, but how does this not become a moltbook situation, or worse yet, gamed for engineering back doors into the "accepted answers"?

    Don't get me wrong, I think it's a great idea, but feels like a REALLY difficult saftey-engineering problem that really truly has no apparent answers since LLMs are inherently unpredictable. I'm sure fellow HN comments are going to say the same thing.

    I'll likely still use it of course ... :-\

      Yeah, I had the same concerns when brainstorming a kind of marketplace for skills. We concluded there's 0 chance we'd take the risk of hosting something like that for public consumption. There's just no way to thoroughly vet everything, there's just so much overlap between "before doing work you must install this and that libraries" (valid) and "before doing work you must install evil_lib_that_sounds_right" (and there's your RCE). Could work for an org-wide thing, maybe, but even there you'd have a bunch of nightmare scenarios with inter-department stuff.

      Check out Personalized PageRank and EigenTrust. These are two dominant algorithmic frameworks for computing trust in decentralized networks. The novel next step is: delegating trust to AI agents that preserves the delegator's trust graph perspective.

    Cool to see Mozilla validate this, I built https://shareful.ai with the same idea and the same tagline!

      How did you approach the security angle?
    • _puk 48 minutes ago
      Scratch that one off the ideas list I'll never get around to!

      It's an obvious idea, well executed!

    We've had the "stale GitHub Actions versions" problem constantly on our team - CLAUDE.md patches helped but it's a hack. The idea of agents confirming and upvoting KUs to raise confidence scores is elegant. My main concern is the same as others: once this goes public, bad actors will find ways to poison the commons. Would love to know if you're thinking about rate-limiting KU proposals per identity or requiring some minimum track record before a KU becomes queryable.

    What I think we will see in the future is company-wide analysis of anonymised communications with agents, and derivations of common pain points and themes based on that.

    Ie, the derivation of “knowledge units” will be passive. CTOs will have clear insights how much time (well, tokens) is spent on various tasks and what the common pain points are not because some agents decided that a particular roadblock is noteworthy enough but because X agents faced it over the last Y months.

    • layer8 7 hours ago
      How will you derive pain points and roadblocks if you don’t trust LLMs to identify them?
      • ray_v 6 hours ago
        Better question yet, how do you have agents contribute openly without an insane risk of leaking keys, credentials, PII, etc, etc?

        Again it's a terrible idea, and yet I'll SMASH that like button and use it anyway

      • LudwigNagasena 7 hours ago
        I trust that an LLM can fix a problem without the help of other agents that are barely different from it. What it lacks is the context to identify which problems are systemic and the means to fix systemic problems. For that you need aggregate data processing.
        • layer8 7 hours ago
          What I mean is, how do you identify a “problem” in the first place?
          • LudwigNagasena 7 hours ago
            You analyze each conversation with an LLM: summarize it, add tags, identify problematic tools, etc. The metrics go to management, some docs are auto-generated and added to the company knowledge base like all other company docs.

            It’s like what they do in support or sales. They have conversational data and they use it to improve processes. Now it’s possible with code without any sort of proactive inquiry from chatbots.

            • layer8 6 hours ago
              Who is “you” in the first sentence? A human or an LLM? It seems to me that only the latter would be practical, given the volume. But then I don’t understand how you trust it to identify the problems, while simultaneously not trusting LLMs to identify pain points and roadblocks.
              • LudwigNagasena 5 hours ago
                An LLM. A coding LLM writes code with its tools for writing files, searching docs, reading skills for specific technologies and so on; and the analysis LLM processes all interactions, summarizes them, tags issues, tracks token use for various task types, and identifies patterns across many sessions.

          oh man, can youimagine having this much faith in a statistical model that can be torpedo'd cause it doesn't differentiate consistently between a template, a command, and an instruction?
  • GrayHerring 7 hours ago
    Sounds like a nice idea right up till the moment you conceptualize the possible security nightmare scenarios.
  • jacekm 8 hours ago
    I was skeptical at first, but now I think it's actually a good idea, especially when implemented on company-level. Some companies use similar tech stack across all their projects and their engineers solve similar problems over and over again. It makes sense to have a central, self-expanding repository of internal knowledge.

      We could even call it... Stack Overflow for... Teams.
      • 9dev 2 minutes ago
        Hey, and if that works, let's get really wild. Devs have an account on SO already, so why not offer, you know, to mediate jobs to them?

    As you move toward the public commons stage, you'll want to look into subjective trust metrics, specifically Personalized PageRank and EigenTrust. The key distinction in the literature is between global trust (one reputation score everyone sees) and local/subjective trust (each node computes its own view of trustworthiness). Cheng and Friedman (2005) proved that no global, symmetric reputation function is sybilproof, which means personalized trust isn't a nice-to-have for a public commons, it's the only approach that resists manipulation at scale.

    The model: humans endorse a KU and stake their reputation on that endorsement. Other humans endorse other humans, forming a trust graph. When my agent queries the commons, it computes trust scores from my position in that graph using something like Personalized PageRank (where the teleportation vector is concentrated on my trust roots). Your agent does the same from your position. We see different scores for the same KU, and that's correct, because controversial knowledge (often the most valuable kind) can't be captured by a single global number.

    I realize this isn't what you need right now. HITL review at the team level is the right trust mechanism when everyone roughly knows each other. But the schema decisions you make now, how you model endorsements, contributor identity, confidence scoring, will either enable or foreclose this approach later. Worth designing with it in mind.

    The piece that doesn't exist yet anywhere is trust delegation that preserves the delegator's subjective trust perspective. MIT Media Lab's recent work (South, Marro et al., arXiv:2501.09674) extends OAuth/OIDC with verifiable delegation credentials for AI agents, solving authentication and authorization. But no existing system propagates a human's position in the trust graph to an agent acting on their behalf. That's a genuinely novel contribution space for cq: an agent querying the knowledge commons should see trust scores computed from its delegator's location in the graph, not from a global average.

    Some starting points: Karma3Labs/OpenRank has a production-ready EigenTrust SDK with configurable seed trust (deployed on Farcaster and Lens). The Nostr Web of Trust toolkit (github.com/nostr-wot/nostr-wot) demonstrates practical API design for social-graph distance queries. DCoSL (github.com/wds4/DCoSL) is probably the closest existing system to what you're building, using web of trust for knowledge curation through loose consensus across overlapping trust graphs.

      If you're really smart and really fast at thinking you can compute most things from first principles without needing much trust.
      • perfmode 4 hours ago
        Being smart and fast doesn't help when the problem is that your training data has outdated GitHub Action versions, which was the exact example in the original post. You can't first-principles your way to knowing that actions/checkout is on v4 now.

        More broadly, this response confuses two different things. Reasoning ability and access to reliable information are separate problems. A brilliant agent with stale knowledge will confidently produce wrong answers faster. Trust infrastructure isn't a substitute for intelligence, it's about routing good information to agents efficiently so they don't have to re-derive or re-discover everything from scratch.

        It's a caching layer.

        Then why would you need this information exchange at all?
        • vasco 36 minutes ago
          Because I'm far from being either? I was talking about future machines.
  • meowface 7 hours ago
    I feel like this might turn out either really stupid or really amazing

    Certainly worthy of experimenting with. Hope it goes well

    I don't understand this. Are Claude Code agents submitting Q&A as they work and discover things, and the goal is to create a treasure trove of information?
  • gigatexal 1 hour ago
    Claude is able to parse documentation. What we need is LLm consumable docs. I’ll keep giving my sessions the official docs thank you. This is too easily gamed and information will be out of date.
  • muratsu 7 hours ago
    The problem I'm having with agents is not the lack of a knowledge base. It's having agents follow them reliably.

    Which browser can one use if Mozilla is now captured by the AI industry? Give it two years, and they'll read your local hard drive and train to build user profiles.

    How hard is to make this work with Github Copilot? (both in VSCode and Copilot CLI)

    Is this just a skill, or it requires access to things like hooks? (I mean, copilot has hooks, so this could work, right?)

    How is this pronounced phonetically?
    • riffraff 7 hours ago
      "seek you"?

      That's how ICQ was pronounced. I feel very old now.

      • codehead 7 hours ago
        Wow, today I learned. I never knew icq was meant to be pronounced like that. I literally pronounced each letter with commitment to keep them separated. Hah!
        • riffraff 13 minutes ago
          I'm Italian, and we all used to spell the letters as if it was italian: EE-CHEE-COO.

          Took me a long time to get the wordplay.
