Changes things 3Claude Code: ask
  • diagnoseRuntime + theme + settings harmony check.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Runtime + theme + settings harmony check. Free-text symptom (e.g., 'cart drawer feels slow', 'badges not appearing') OR kit-scoped check. Returns categorized issues (theme_compat / settings_conflict / runtime_error / a11y / performance) with severity and optional fix_plan_id callable via execute(). health_score 0-100.
  • planMASTER KEY tool.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    MASTER KEY tool. Analyzes natural-language merchant intent ('make my buttons feel premium', 'wellness brand vibe', 'BFCM aggressive') and returns a structured plan of settings to change across Flowpack's Button + Cart + Badge + Variant + Frosty Pill kits. Handles single tweaks (one hover style) and full overhauls (50+ settings) with the same call. Returns opaque plan_id, change count, preview URL, and reasoning. ALWAYS call preview() before execute().
  • recommendGoal-oriented recommendation engine.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Goal-oriented recommendation engine. Scenarios: 'personalized_4_plans' (returns 4 diverse plans — safe / aspirational / seasonal / conversion-tested), 'preset_for_brand', 'color_palette_for_theme', 'touch_target_for_devices', 'motion_density_for_audience', 'seasonal_for_calendar', 'diagnostics_first_check'. Use for proactive suggestions when merchant intent is unclear.
Only reads 2Claude Code: allow
  • browseUniversal catalog reader.No findings

    Why it is in this group

    • The name "browse" says "browse": a word for reading.
    Description, as the server wrote it
    Universal catalog reader. Routes by domain ('kits', 'presets', 'palettes', 'seasonal', 'settings', 'decorations', 'effects', 'diagnostics', 'anatomy', 'compatibility') with optional facet filter (e.g., 'button.hover') and free-text query. Returns paged items with id/name/description and metadata-only marker. Use this for ANY merchant question about 'what options are available' or 'show me X'.
  • explainNatural-language explanation of a plan_id (what it does) or setting_path (what one setting controls).No findings

    Why it is in this group

    • The name "explain" says "explain": a word for reading.
    Description, as the server wrote it
    Natural-language explanation of a plan_id (what it does) or setting_path (what one setting controls). Audience: merchant (default), developer, or reviewer. Detail: brief (1-2 sentences) or deep (full context + related settings + a11y notes). Use when merchant asks 'what does this do' or 'why this preset'.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
