    "title": "Velocity Sickness: What Happens When Your Whole Team Gets 10x Faster — Matt Dailey, Ref.",
    "one_liner": "Ref's CEO Matt Dailey names \"velocity sickness\" — the stress and output-without-impact that hits when AI makes a whole team 10x faster — and argues the fix is moving your unit of work from the ephemeral chat to a durable, shared planning doc where humans still own the decisions.",
    "summary": "Dailey catalogues four failures that appear when AI speeds everyone up (too many PRs, sprinting in all directions, \"declaring agent bankruptcy\", and agents making critical decisions) and bundles them as velocity sickness: \"output without impact\". He argues the shape of engineering work has changed — planning and polish are now the human parts, implementation belongs to the agent — while the IDE and the chat were built for implementation. His proposed answer is a \"decision layer\" tool centred on docs rather than chats: the agent is the action, the doc is the state, so agents are stateless, spawnable in parallel, and the key decisions are durable, shared and human-owned. The measured success signal is people planning and then deliberately not building some plans — shifting from code velocity to idea velocity.",
    "key_points": [
      "Four symptoms of velocity sickness, each an individual problem magnified at team scale: too many PRs to merge (merge conflicts, merge queue breaks down); moving in many directions at once; declaring agent bankruptcy; and — the most important — critical decisions being made by agents.",
      "Agent bankruptcy: you crank all day with ~12 terminals open, step away, come back next morning to \"a room of strangers\", kill them all and start over — so you redo the same work and spend tokens twice.",
      "Letting an agent make a critical decision means you cede ownership of that code; at company scale, if engineers across the team do it, \"you no longer own the product.\"",
      "The non-engineer parable: a newsletter writer with a sophisticated (\"very very much not slop\") agent pipeline is \"basically writing a book every week\" — but the audience isn't reading a book a week. Unread pages are the analogue of shipped code that doesn't land.",
      "The shape of work flipped: old process was plan → implement (heads-down, isolated) → polish, and the IDE was built for implementation and polish by an individual. New process is plan → agent implements (\"arguably should not even be on this slide cuz it's not our human work anymore\") → human polish. Planning is the stage that changed most.",
      "Chats are a relic of building for implementation: isolated, ephemeral and \"brain off\". Decisions get made inside them, never shared with the team, and the agent's \"this is the recommended option\" prompt gets rubber-stamped without thought.",
      "He explicitly distinguishes his proposal from two adjacent things: plan mode is good but \"largely a rich chat message\" in the same isolated, ephemeral environment; full spec-driven development operates at the product level, too far from the engineering reality of needing to understand your system. He wants the middle — a durable, shared, long-lived artefact.",
      "The conceptual flip is separating the agent (action) from the doc (state): you do context engineering in the doc so every agent is stateless and starts from the same place, which gives more parallel agents, a durable decision log that doesn't depend on an LLM summarising and maybe picking the wrong things, and a shared view of what was decided. This moves the review point earlier — code review gets simpler because \"what actually matters here\" is already agreed — and agent bankruptcy stops being a thing because you rebuild human context by reading the doc.",
      "Good sign when teams adopt it: people plan and then don't implement some plans — they explore ideas, then prioritise which are worth building. That's the shift from code velocity to idea velocity, escaping \"prototype gravity\" and one path down the idea maze."
    ],
    "takeaways": [
      "Think of your work in two gears — planning and polish — and notice when you drift from one into the other inside a single session, then ask whether the tool you're in still serves what you're doing at that moment.",
      "Treat the plan as a \"portal to the software system\": use AI's strength at finding what's related to pull the relevant contours of a complex system onto the table, then organise the pieces to express how you want the system to grow.",
      "Share a plan with a human teammate, not just with your agent — it feels unnatural, but teammates hold context in their heads and give good feedback.",
      "Move alignment ahead of implementation: agree the key decisions in a durable shared doc before anyone spends even a day going deep with AI on a prototype.",
      "Keep decisions out of the chat: put state in the doc so agents can be spawned stateless from the same context and the decision log survives the session."
