Timeline

  1. Start

    ChatGPT conversation reviewed

    Key question: can ForgeKit prove it compounds, not just builds fast?

  2. 20m

    Baseline framing decided

    The next proof is not 'can AI build fast' — it's 'can the engine remember, reuse, and improve without becoming a junk drawer'

  3. 40m

    Last 5 sessions scored

    Read all retros, checked actual Claude API routes against Pattern Registry

  4. 60m

    Three changes applied

    compounding{} added to schema + ignition, AI call check strengthened, planning-engine retro back-filled

  5. 75m

    Engine sessions verdict

    Honest answer reached: valuable but approaching diminishing returns

What shipped

  • compounding{} block — new required field in _SCHEMA.md with proof, what_started_ahead, what_becomes_cheaper_next_time, missed_reuse

  • compounding{} JSON template added to ignition.md §7 HARVEST — same weight as reuse{}

  • ignition.md §3 ORIENTATION — AI call check now names client.messages.create as the trigger and requires logging the check in reuse.patterns_checked

  • forgehome-planning-engine retro — first honest retroactive reuse{} + compounding{} blocks, first named missed_reuse entry

  • Compounding baseline document — retroactive scores across 5 sessions with pattern analysis

“Fake compounding looks like more markdown, more rules, more named concepts. That is ForgeKit Theater.”
