# Performance Optimization — Stage 6C Read the detailed guide at `${CLAUDE_SKILL_ROOT}/references/optimize-detailed-guide.md` for the complete optimization procedures, teammate spawn prompts, benchmark patterns, and report templates. Lead a multi-agent performance optimization project. Audit the complete product against PRD performance budgets, identify bottlenecks, and implement optimizations. **Stage Sequence** (recommended ordering): Stage 5B → (6A ‖ 6B ‖ **6C (this stage)**) → 6E → 6F → 6G → 6D → 6H → 6V → 6R → 6P/6P-R → 7 (Deploy). Note: 6A, 6B, and 6C run **in parallel** (each in a separate session). If running in parallel, commit 6A changes as soon as 6A completes to avoid config file conflicts — see CLAUDE.md § "Stage 6 ordering". ## Prerequisite Checks Before any optimization work, verify: 1. Check that `./plancasting/_audits/implementation-completeness/report.md` exists and shows PASS or CONDITIONAL PASS. If missing, STOP: "Stage 5B report not found — run Stage 5B before starting Stage 6 audits." (Override: if the operator explicitly confirms 5B was intentionally skipped, proceed with a WARN.) 2. If `./plancasting/_audits/security/report.md` (6A) exists, read it to understand security changes that must not be undone during optimization (validation, CSP headers, rate limiting). 3. If `./plancasting/_audits/accessibility/report.md` (6B) exists, read it to understand accessibility patterns (focus ring styles, semantic HTML, `prefers-reduced-motion`) that should n
