/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
-
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.
-
Open the synthesis prompt. Read
.flywheel/prompts/plan-synthesize-best-of-all-worlds.md. Copy it
into a fresh GPT Pro (web) conversation.
-
Paste the base plan, then each competitor. Label each
clearly.
-
Receive git-diff revisions. GPT Pro will produce a list of
diff-style changes integrating the best ideas.
-
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.
-
Iterate. Use .flywheel/prompts/plan-refine.md in fresh GPT
Pro conversations 4–5 more times until convergence.
-
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.
