# Update template repo with latest Claude Code best practices ## Arguments - `--dry-run` — Only report recommendations, don't change files - `--focus <area>` — Focus on a specific area (hooks, skills, agents, rules, docs, settings, claude-md) Parse arguments from `$ARGUMENTS`. Default: full update, live mode. ## Step 1: Online research (MANDATORY) Search for ALL of the following using WebSearch. Run searches in parallel where possible: 1. "Claude Code changelog 2026 latest release notes" 2. "CLAUDE.md best practices configuration guide" 3. "claude code hooks PostToolUse PreToolUse Stop new hooks" 4. "claude code skills SKILL.md agent skills standard" 5. "claude code settings.json schema permissions deny" 6. "anthropic claude code new features update" 7. "context engineering claude code best practices" 8. "claude code community CLAUDE.md examples github" 9. "trufflehog latest CLI flags filesystem git scan only-verified best practices" 10. "npm audit fix --force breaking changes best practices 2026" Collect ALL relevant findings before proceeding. When the trufflehog/npm-audit findings land, reconcile them against `scripts/project-freshness.sh` (the local freshness pass). If trufflehog's CLI surface has shifted (renamed flags, changed `--only-verified`/`--results` semantics, new scan subcommands) or npm's audit/remediation guidance has moved, update that script and the matching Step 8c instructions in `scripts/sync-prompt.md` + the freshness step in `.claude/skills/sync
