plan-synthesize

# /plan-synthesize — best-of-all-worlds Feed competing plans into a single GPT Pro session and produce a hybrid that integrates the strongest ideas from every input. ## Workflow 1. **Pick a primary.** Choose the best of the competing plans as your "base" — usually GPT Pro's. Its content gets the git-diff revisions applied to it. 2. **Open the synthesis prompt.** Read `.flywheel/prompts/plan-synthesize-best-of-all-worlds.md`. Copy it into a fresh GPT Pro (web) conversation. 3. **Paste the base plan, then each competitor.** Label each clearly. 4. **Receive git-diff revisions.** GPT Pro will produce a list of diff-style changes integrating the best ideas. 5. **Apply in-place with Claude / Codex.** Use the prompt in `.flywheel/prompts/plan-integrate-synthesis.md`. The agent applies the diffs to `.flywheel/plans/<date>-<slug>-gpt-pro.md` (renaming it to `-hybrid.md` is a good practice) and reports which revisions it wholeheartedly agrees with, somewhat agrees with, or disagrees with. 6. **Iterate.** Use `.flywheel/prompts/plan-refine.md` in fresh GPT Pro conversations 4–5 more times until convergence. 7. **Sanity overshoot.** Once per synthesis, run `.flywheel/prompts/overshoot-mismatch-hunt.md` to catch elements the model silently dropped. ## Output A single hybrid plan at `.flywheel/plans/<date>-<slug>-hybrid.md`. This is the one you'll feed into `/plan-to-beads`.
