Add 36-slot SimpleContainer inventory to SteveEntity with NBT persistence - Mining collects blocks into inventory instead of dropping on ground - Building consumes materials from inventory (skipped in creative mode) - Add creativeMode config option (default: true) for unlimited materials - Fix build plan fallback: procedural generation was commented out - Fix collaborative build: Steve now reassigns to other quadrants when done - Update LLM prompt to reflect creative/survival mode rules - Update PromptBuilder to show inventory or [unlimited] based on mode - Add block drop mapping (stone -> cobblestone, etc.) - Add material mining aliases (cobblestone, oak_planks, glass, etc.) Co-Authored-By: Claude Opus 4.7 --- config/steve-common.toml.example | 5 +- .../ai/action/CollaborativeBuildManager.java | 20 +++- .../action/actions/BuildStructureAction.java | 73 ++++++++++-- .../ai/action/actions/MineBlockAction.java | 66 +++++++++-- .../ai/action/actions/PlaceBlockAction.java | 26 ++++- .../java/com/steve/ai/config/SteveConfig.java | 7 +- .../java/com/steve/ai/entity/SteveEntity.java | 106 +++++++++++++++++- .../java/com/steve/ai/llm/PromptBuilder.java | 63 ++++++++--- 8 files changed, 319 insertions(+), 47 deletions(-) diff --git a/config/steve-common.toml.example b/config/steve-common.toml.example index 0246878c..ce8a3343 100644 --- a/config/steve-common.toml.example +++ b/config/steve-common.toml.example @@ -18,7 +18,10 @@ # Allow Steves to respond in chat enableChatResponses = true -

Now the server event handler checks both the manager and the world for existing Steve entities before spawning, and registers entities loaded from save data instead of destroying them. The static stevesSpawned flag is removed in favor of runtime checks against the manager's active count.

and add configurable build delay - Remove StructureGenerators and its test (procedural generation deprecated) - Add BUILD_TICK_DELAY config for controlling block placement speed (default 20 ticks/block) - Add restock cooldown to WarehouseManager to prevent rapid auto-restock - Increase SteveEntity RESTOCK_INTERVAL from 100 to 1200 ticks - Add duckyausautoroute schematic to config -

New commands queue while a ReAct is running; the next one starts automatically when the current agent finishes. - Replace the Plan-and-Execute path in ActionExecutor: incoming commands go into pendingCommands, drainNextCommand starts a ReActAgent, and tick() feeds ActionResult observations back. No fallback to the old plan-and-execute path. - ResponseParser parses single ReAct steps (thought/action/ parameters/is_final/final_answer); PromptBuilder emits a ReAct system prompt and per-step user prompt; TaskPlanner exposes buildReActParams and a public getAsyncClient. - SteveConfig gains a [react] section (maxSteps, observationTruncateChars, maxConsecutiveFailures). ReAct is the only mode; no enable toggle.

Add BuildPhase enum + BuildProject data class for plan-then-build - PlanBuildAction drives FEASIBILITY → DESIGN → AWAITING_DESIGN_APPROVAL → CONSTRUCTION → COMPLETED. Dashboard / /steve approve kicks off construction directly with no second confirmation; AWAITING_ACCEPTANCE is kept as an enum value for source compatibility. - PlanBuildAction.runConstruction walks each loaded template at BUILD_TICK_DELAY cadence via ServerLevel.setBlock; Steve pathfinds within 6 blocks of the target and skips occupied cells. - 7 PlanEvent POJOs + PlanEvent marker interface published through a dedicated plan event bus. - PlanDashboardServer: 127.0.0.1:8765 embedded HTTP server with /events (SSE), /command, /chat, /plan handlers. CORS allows http://localhost:5173; Vite dev server proxies these paths. - /steve plan / approve / halt / status / dashboard subcommands wired into SteveCommands. SteveGUI forwards /steve input directly to the command tree. - BuildDesignFormatter renders the design doc to chat (header / body / footer), dropping the obsolete 30-second auto-approve prompt. - Memory: SteveMemory.queryLongTermMemory now calls mempalace:mempalace_query (was mempalace_list_drawers). - BuildStructureAction marked deprecated; CoreActionsPlugin keeps it registered for the legacy path. Procedural StructureGenerators is already removed; PlanBuildAction.runDesign fails fast if no NBT matches. - Dashboard port + frontendUrl exposed via [dashboard] config section; build.gradle forces UTF-8 for the runClient task. - Docs: README, 00-overview, 01-architecture, 02-actions, 03-config, 05-prompt-builder, 09-memory, 10-structures, hackathon/02-plan-mode, hackathon/施工流程 refreshed to match the new behavior; LF warnings on the docs/ files are line-ending normalization, not content.

Subscribes to /events as SSE, mirrors plan.created / plan.design_ready / plan.phase_changed / plan.approved / plan.halted / plan.chat / plan.log into a single useReducer state, and renders the active BuildProject's blocks as Three.js InstancedMesh so the structure preview updates the moment the design doc lands. Includes /plan, /command (approve / halt) and /chat POST helpers with CORS fallback for direct localhost access. check-demo.py / shoot-demo.py / verify-threejs.py are local helpers for recording and validating demo footage against the running dashboard; they are not part of the mod build.
