Research and planning documents are tactical execution artefacts to be thrown away and regenerated, because tokens are cheap and a doc that has drifted from the codebase costs you time.

Our reading — they may agree, disagree or merely touch the same thing. Closest first: a shared subject counts for most, then how near the wording is.

• A plan that spells out every line of code to change gives you no leverage: it costs as long to read as the pull request, so you end up skimming it and reading the code twice. DHDex Horthy15 Jul 2026similar wording
• The case for sweating every line of code was premised on humans doing the modifications, and it now survives only because tokens are scarce. DHDavid Heinemeier Hansson26 Aug 2026similar wording
• Having an AI agent write tests costs tokens in the short run and saves them in the long run, because the classic failure is that the code does not work. KBKent Beck1 Jul 2026similar wording
• Every abstraction in agentic programming — RAG, memory, agentic history, structured output — is just a different way of passing tokens into a model, and understanding that beats learning any of them. DHDex Horthy15 Jul 2026similar wording
• Most organisations are bottlenecked on ideas, vision and taste rather than on implementation, so making code cheap does not make them productive. DHDavid Heinemeier Hansson26 Aug 2026similar wording
