description	Iteratively build an application or game phase-by-phase in clean subagents, reviewing each phase and refining the build-* skills / rules until each is optimal, then summarizing.

Purpose: exercise and polish the build- skills and the rules they reference*, using a concrete app/game prompt as the test case. You are improving the general guidance, not the one-off output.

Procedure

1. Resolve target to its ordered phases. A composite target expands to its pipe — build-feature → its /build-* layer steps; build-application / build-game → build-feature for the base and each peer, then build-app-entry. A single build-<phase> target is just that one phase.

2. For each phase, in order: a. Run it in a fresh subagent with constrained context (/x-subagent): give the subagent only the phase skill (/<phase>), the app/game prompt, and the files on disk from prior phases — nothing about this loop or earlier attempts, so every re-run differs only by any edits you made to the guidance. b. Review the phase output in a subagent with /review. c. If /review is not OPTIMAL: fix the root cause in the guidance — edit the phase skill or a rule it references. Keep every edit concise and general: improve it for all apps, never encode anything specific to this prompt. (For a pure code slip with sound guidance, just re-run.) Do not hand-patch the generated code. d. Re-run from (a), up to maxIterations (default 4) attempts. Move to the next phase once it reviews OPTIMAL — or the cap is hit (record that it did not converge). e. Record: the phase, its iteration count, and every skill/rule file you edited.

3. Final review (read-only): run /review over the whole product. Change nothing. Then summarize:

   • per-phase iteration counts,
   • which phase skills and which rules were edited, and why,
   • overall outcome (which phases converged, which hit the cap).

Every phase runs in its own constrained subagent so re-executions during polishing stay consistent — the edited skill/rule is the only variable between a phase's attempts.
