    "title": "If we want them to do Knowledge Work, design them as Knowledge Agents — Benjamin Clavié, Mixedbread",
    "one_liner": "Ben Clavié argues that agents doing non-code knowledge work need to be designed like knowledge workers — optimized search tools plus a partner/associate style breakdown into searcher sub-agents — and shows this closes the human-agent 'oracle gap' on PDF benchmarks by 40%.",
    "summary": "Clavié (Mixedbread, retrieval) claims agentics has generalized from a special case — coding — that is unusually easy: code has durable cues, a greppable surface, and humans hand agents extremely narrow, pre-decomposed tasks. Real knowledge work is contextual and meaning-driven, the query starts from an intent, and the same clue ('30 days') can mean a deadline, a grace period or a retention rule. He maps centuries of human knowledge-work design — the tool loop (writing → Alexandria's catalog → bibliographies → Dewey → search engines) and the organization loop (polymath → monasteries → universities → specialized firms) — onto agent design, then backs it with BrowseComp-Plus and MMQA numbers showing that better retrieval tools raise the ceiling and a partner/associate orchestration pattern closes the remaining gap.",
    "key_points": [
      "Two definitions of knowledge work: your main input is information (not physical material) and your output is an actionable judgment or decision; and topologically, 'if you need search it's a knowledge problem and if it's a knowledge problem you need search'.",
      "Code is an unrepresentative form of knowledge: durable cues (identifiers, files, paths), a greppable surface (keywords, method definitions), and above all extremely narrow tasks — you give a coding agent a ticket, you don't say 'discover a new programming paradigm'. Non-code knowledge has implicit meaning and ambiguous clues.",
      "The tool loop and the organization loop are actually one self-optimizing loop: new knowledge → better tools → new workflows and roles → retrained workers who produce more knowledge → need for better tools.",
      "Tooling is not a neutral add-on — it decides whether a task is scalable and cheap enough to be worth doing. Finding a manuscript in Alexandria took 2-3 weeks without the catalog and 10 minutes with it.",
      "On BrowseComp-Plus (deep-research benchmark over a bounded document set, ~200k docs), an unoptimized BM25 baseline sits at 60% accuracy; optimizing the baseline takes it to 70-80; the best hybrid harness reaches the high 90s. Clavié stresses there is no single BM25 — there are hundreds — so you must always optimize your baselines.",
      "The headline result is efficiency, not accuracy: 90.2% is reached with 20% fewer tool calls — 20% fewer tokens, '20% free cash' — and roughly 5% of the spend of the unoptimized baseline. 25 calls kills the workflow; 8 calls makes it adoptable.",
      "On MMQA (Hugging Face + Snowflake, PDF-based enterprise tasks with OCR versions), BM25 caps both Gemini 3 and a human at the same ceiling — meaning even a human with unlimited searches can't retrieve the right information with that tool. Multimodal search (Jina, Mixedbread) that reads PDFs and tables directly produces a big jump.",
      "Even with good multimodal search the agent scores 88.9 vs a human's 99.4 over 10 turns. Adding the Mixedbread agent — a main agent that decomposes the question, writes aspect queries, and dispatches searcher sub-agents that return memos — adds 3.5 points and cuts the 'oracle gap' (perfect documents vs your search system) from ~10 points to 6, a 40% reduction in mistakes from architecture alone."
    ],
    "takeaways": [
      "Copy the law-firm shape, not the coding-agent shape: have the orchestrator break an open-ended request into aspects and dispatch searcher sub-agents that return memos, because unlike with Claude Code the user hasn't already decomposed the query for you.",
      "Always optimize your baselines before dismissing a retrieval method — 'BM25 is bad' usually means an unoptimized BM25, and the gap between the two is 60% vs 80% accuracy.",
      "Measure tool calls and tokens, not just accuracy: the same score at 20% fewer calls is what makes a knowledge workflow cheap enough to actually deploy.",
      "Don't overfit on tools — reach for a better tool when you hit a ceiling. Diagnose ceilings with an oracle-gap style check (perfect documents vs your search system), and note that a human failing with your tool means the tool, not the model, is the bound.",
      "Co-design tools with agents and teach them the full set of primitives — grep, BM25 and semantic search. Agents default to writing grep/BM25 queries because grep is everywhere in the training data, but you can't grep a PDF.",
      "Don't plan on long context replacing orchestration: even a 100M-token context is expensive and still isn't half of one US state's legal code."
