connectConnect to a live Balatro instance and keep its bridge socket open. Read balatro://instances for the current indices and pass instance_index, or omit it when exactly one instance is running. Connecting changes no default: actions and live resources address instances by instance_index and open their own sockets on demand.disconnectRelease the bridge socket held for a live Balatro instance. Read balatro://instances for the current indices and pass instance_index, or omit it when exactly one instance is running. Nothing else changes: later actions and resource reads reconnect on demand.balatro_select_blindSelect the current blind to begin the round.balatro_skip_blindSkip the current blind, forfeiting its cash reward in exchange for a tag reward.balatro_play_handPlay the selected cards as a poker hand, scoring them against the blind's chip target.balatro_discard_handDiscard the selected cards and draw replacements, consuming one discard for the round.balatro_reroll_shopReroll the shop offerings, spending the current reroll cost.balatro_reroll_bossReroll the upcoming Boss Blind for $10 during blind selection. Requires Director's Cut (once per Ante) or Retcon (unlimited rerolls), sufficient spendable money, and no reroll already in progress.balatro_leave_shopLeave the shop to end the round.balatro_cash_outCash out round-end rewards.balatro_skip_boosterClose an open booster pack, forfeiting remaining picks.balatro_restartRestart the current run with the same deck, stake, and seed.- +15 more on the listing page

query_instancesQuery Roblox instances: get, children, find child/descendant, wait for child, class info, search by name/class. [PRO] file_tree, project_structure, descendants, ancestors, search by property/tag.mutate_instancesCreate, delete, clone, move, rename, or pivot instances. [PRO] create_tree, mass_create, mass_delete, mass_duplicate, smart_duplicate, scatter.manage_propertiesGet/set properties, attributes, and tags on instances. [PRO] set_calculated, set_relative, mass_set, mass_get, modify_children.manage_scriptsManage script source code: read, write, create, delete, edit lines, search, and validate Luau syntax. [PRO] replace across scripts.manage_uiCreate / update / verify Roblox in-game UI (ScreenGui / Frame / TextLabel / …). Always start with `design_brief`. For ambiguous input, it inspects Studio context and returns candidate brief patches; Do not dump enum lists at the user. An empty StarterGui does not prove runtime UI absence: for an existing-UI review, follow `runtime_review_required`, collect a structured Play Client PlayerGui snapshot, and pass its saved `runtimeEvidenceRef`. Pass relevant repository evidence in `projectContext`; explicit screen job, visual thesis, forbidden defaults, tokens, and approved assets determine the direction without a built-in subject preset. `design_brief` returns a primary-view-first Design Contract and an advisory Layout Plan with neutral regions, AnchorPoint strategy, and responsive behavior; it is not a hard tree preset or style quota. A calling agent may declare provider-neutral image generation capability through `agentCapabilities`; missing or unavailable capability must use the explicit existing, user-provided, Creator Store, or assetless fallback. Keep the returned `brief_id`, `design_contract`, and `layout_plan` through creation, update, preview, and check. The asset recommendation gate considers user references, project assets, existing UI, and user-approved `manage_assets.search` intent; do not use a recommendation until the user accepts it. After each meaningful create or update, preview the representative primary view and submit a calling-agent critic verdict (`recompose`, `refine`, or `approved`) with `visualReview`. Read `primary_visual_verdict`, `functional_safe`, `responsive_requirement`, `responsive_ready`, `required_dimensions`, and `readiness` separately from mutation success. Responsive evidence blocks readiness only when the Design Contract marks it required. Read `weppy://ui-studio/guide` for the authoring workflow, `weppy://ui-studio/tokens` for optional visual examples, and `weppy://ui-studio/functional-rules` for machine-readable advisory evidence rules. Design Check permits `priority_high` only for observed functional visual failures such as meaningful overlap, unreadable content, invalid geometry, or primary-view occlusion; style-only findings remain medium or low.manage_lighting[PRO] Configure environment: lighting, atmosphere, sky, terrain properties, time of day.manage_selectionGet, set, or clear selection. [PRO] context, details, add/remove items, watch changes.manage_cameraCamera operations: get info, focus on instance/position, suggest view, capture Edit-mode viewport screenshot (Edit mode only; not usable during playtest).manage_tween[PRO] Tween service: create, play, pause, cancel tweens for smooth animations.manage_audio[PRO] Audio management: play, stop, pause, resume sounds. Set audio listener.manage_animation[PRO] Animation: load, play, stop animations. Get animation tracks from humanoid/controller.manage_physics[PRO] Physics collision groups: register, set collidable between groups, list groups.- +13 more on the listing page
