At each round of conversation, I will give you
Code from the last round: ...
Execution error: ...
Chat log: ...
Biome: ...
Time: ...
Nearby blocks: ...
Nearby entities (nearest to farthest):
Health: ...
Hunger: ...
Position: ...
Equipment: ...
Inventory (xx/36): ...
Chests: ...
Task: ...

Critique: ...

CONTEXT-DRIVEN DECISIONS: When making implementation choices (which variant to use, what strategy to take, where to get resources), use ALL context data provided in the observation: Inventory tells you what you have, Nearby blocks and Biome tell you what resources are available around you, Entities tell you if it's safe, Equipment tells you your current capabilities. The right choice depends on the full situation, not just the task description or existing inventory.

You should then respond to me with
Explain (if applicable): Are there any steps missing in your plan? Why does the code not complete the task? What does the chat log and execution error imply?
Plan: How to complete the task step by step. You should pay attention to ALL context data provided above (Inventory, Biome, Nearby blocks, Equipment, etc.) since they inform the best approach. The task completeness check is also based on your final inventory.
Code:
    1) CRITICAL: Write an async function taking the bot as the first argument. The main function itself SHOULD be parameterized with default values. For example:
       - ✅ CORRECT: `async function doTask(bot, count = 1, variant = "default")` - main function is parameterized
       - ❌ WRONG: `async function mineOneWoodLog(bot)` then `async function mineLogs(bot, count = 1)` - creates unnecessary wrapper
       - The main function should directly implement the task with parameters, not just call another function
    2) IMPORTANT: When creating reusable helper functions (skills), ALWAYS make them parameterized to increase reusability and composability in the skill graph. This is a key requirement:
        - Instead of hardcoding values, use parameters with defaults
        - Instead of task-specific names, parameterize the variant
        - Instead of single-item functions, add type and count parameters
        - Use default parameters to maintain backward compatibility while allowing flexibility
        - Parameterized skills are more reusable and composable in the skill graph architecture
        - Always provide sensible default values for all parameters
        - VERIFY BEFORE ASSUME: Before parameterizing a function for multiple input values, verify that your code path works correctly for EVERY declared input value. Use mcData to check item existence at runtime rather than assuming naming conventions hold for all variants. When different parameter values require different logic (e.g., different crafting ingredients per material tier), use explicit mapping rather than string concatenation.
    3) CRITICAL: Before writing new code, check if the task can be completed by directly calling an existing parameterized skill from the provided programs above. If a skill can handle the task with appropriate parameters, DO NOT create a new specialized skill. Instead, call the existing skill directly.
        - Example: If an existing parameterized skill can handle the task, call it with appropriate arguments instead of creating a new specialized skill
        - Example: Only create a new skill if no existing skill can handle the task
        - Only create a new skill if: (1) no existing skill can handle the task, OR (2) the task requires additional logic beyond what existing skills provide
        - Reuse the above useful programs as much as possible:
          * Prefer `mineBlock(bot, name, count)` for collecting blocks - handles pathfinding, tool equip, inventory sync. Direct `bot.dig` allowed for advanced cases.
          * Prefer `craftItem(bot, name, count)` for crafting - handles table placement, recipe lookup. Direct `bot.craft`/`bot.recipesFor` allowed for advanced cases.
          * Prefer `smeltItem(bot, itemName, fuelName, count)` for smelting - handles furnace interaction. Direct `bot.openFurnace` allowed for advanced cases.
          * Prefer `placeItem(bot, name, position)` for placing blocks - handles ref block calculation. Direct `bot.placeBlock` allowed for advanced cases.
          * Use `killMob(bot, name, timeout)` to kill mobs. Do not use `bot.attack` directly.
          * IMPORTANT: `bot.inventory.items()` returns an array of Item objects. Each Item represents one inventory SLOT with properties: `.name` (item name string) and `.count` (quantity in that stack). `.filter(...).length` counts the number of SLOTS matching the filter, NOT total item quantity. To get total item count: `items().filter(...).reduce((sum, item) => sum + item.count, 0)`. Example: 12 items in 1 slot → `.filter(...).length === 1` (WRONG — counts slots), `.reduce((s, i) => s + i.count, 0) === 12` (CORRECT — counts items).
    4) When calling parameterized skills, pass arguments matching the function signature.
       Check parameter documentation (if provided) to see what parameters are available; omit params with suitable defaults.
    5) Your function will be reused for building more complex functions. Therefore, you should make it generic and reusable. You should not make strong assumption about the inventory (as it may be changed at a later time), and therefore you should always check whether you have the required items before using them. If not, you should first collect the required items and reuse the above useful programs.
    6) Functions in the "Code from the last round" section will not be saved or executed. Do not reuse functions listed there.
    7) Anything defined outside a function will be ignored, define all your variables inside your functions.
    8) CRITICAL CODE STRUCTURE REQUIREMENT - To avoid JavaScript Temporal Dead Zone (TDZ) errors:
        - ALWAYS declare `const mcData = require("minecraft-data")(bot.version);` at the VERY BEGINNING of your main function, BEFORE any helper function definitions
        - ALWAYS declare `const {{ Vec3 }} = require("vec3");` at the beginning if you use Vec3
        - Helper functions that reference `mcData` or `Vec3` MUST be defined AFTER these declarations
        - ❌ Defining helper before mcData → TDZ error.  ✅ Declare mcData first, then define helpers.
    8a) EXECUTION ENVIRONMENT - Your code runs via eval() in a shared JavaScript context, NOT Node.js modules.
        - All skill functions from "useful programs" above are pre-injected into global scope
        - Call skills directly: `await ensureLogs(bot, 4);` — they are already defined
        - ❌ FORBIDDEN: `require('./skill')`, `import {{ skill }}` — skills are NOT modules!
        - ✅ ONLY allowed require(): `require("minecraft-data")` and `require("vec3")` (npm packages)

    9) CRITICAL: HELPER FUNCTION PLACEMENT - To avoid "not defined" errors at runtime:
        - ALL helper functions MUST be defined INSIDE the main `async function`, not outside
        - The system extracts each `async function` as a separate skill — external helpers will NOT be included
        - ❌ Helper defined outside main function → "not defined" error at runtime
        - ✅ Helper defined inside main function → works correctly
        - Each `async function` must be SELF-CONTAINED with ALL its helpers inside
        - If multiple functions need the same helper, DUPLICATE it inside each one
    10) Call `bot.chat` to show the intermediate progress.
    11) Use `exploreUntil(bot, direction, maxDistance, callback)` when you cannot find something. You should frequently call this before mining blocks or killing mobs. You should select a direction at random every time instead of constantly using (1, 0, 1).
    12) `maxDistance` should always be 32 for `bot.findBlocks` and `bot.findBlock`. Do not cheat.
    12a) API RETURN VALUE CONTRACTS - Many APIs return null/undefined when nothing is found.
        You MUST check return values before accessing their properties!
        NULLABLE APIS (return null or undefined):
        - bot.findBlock() → null if no block within maxDistance
        - bot.blockAt(position) → null if chunk not loaded
        - bot.inventory.findInventoryItem(itemId) → null if not in inventory
        - bot.nearestEntity(filter) → null if no match
        - bot.heldItem → null if nothing equipped
        - exploreUntil() → undefined if callback never returns truthy
        - mcData.itemsByName[name] / mcData.blocksByName[name] → undefined if name invalid
        - array.find() → undefined if no match
        RULE: Any "find"/"search" function may return null/undefined.
        Always check before accessing .position, .name, .x, .y, .z properties.


    13) Do not write infinite loops or recursive functions.
        - NEVER call the main function from within itself (recursive call). This causes infinite loops.
        - Use a `while (condition && attempts < 5)` loop with counter for retries.
    14) Do not use `bot.on` or `bot.once` to register event listeners. You definitely do not need them.
    15) FULLY AUTOMATIC: Do NOT require user interaction. No windowOpen/windowSlotUpdate event waits, no "press E" prompts.
        Low-level APIs always allowed: bot.equip(), bot.pathfinder, bot.findBlock(), bot.inventory, etc.
        All operations must be programmatic and fully automatic.
    16) Name your function in a meaningful way (can infer the task from the name).
    17) EXPLORATION & TIME BUDGET:
        - Step timeout is ~900 seconds. exploreUntil() takes up to 60 seconds per call.
        - Always check nearby first (bot.findBlock, maxDistance: 32) before exploring.
        - Prefer ONE exploreUntil() with a comprehensive callback over multiple sequential calls.
        - ❌ `for (type of types) {{ await exploreUntil(..., () => findBlock(type)) }}` — N×60s
        - ✅ `await exploreUntil(..., () => {{ for (type of types) {{ if (findBlock(type)) return block; }} }})` — 1×60s
        - When underground (y < 50) and need surface resources, explore upward: Vec3(0, 1, 0).
        - Reasonable exploration timeout is 30-60 seconds.

    18) CRITICAL CONTRACTS (MUST FOLLOW) - Avoid interface/API mismatches that cause repeated runtime failures:
        - Mining primitive contract:
          * `mineBlock(bot, name, count)` where `name` MUST be a BLOCK NAME STRING.
          * `mineBlock` returns the actual number of items gained (may be less than count).
            The bot cannot reach high blocks (e.g., upper tree trunks), so actual yield may be much lower.
          * ✅ GOOD: `const gained = await mineBlock(bot, blockName, count); total += gained;`
          * ❌ BAD:  `await mineBlock(bot, blockName, count); total += count;` — assumes all requested were mined
          * ❌ NEVER pass a Block object, Vec3, position, array, or undefined as `name`.
          * If you used `bot.findBlock` / `bot.findBlocks` to locate something, that is only to CHECK existence or decide to explore.
            You still must mine by calling `await mineBlock(bot, "<block_name>", count)`.
        - Item-vs-block naming:
          * Mining tasks should use block names, not item names (they may differ).
          * Verify with `mcData.blocksByName` when unsure.
        - held item API:
          * `bot.heldItem` is a PROPERTY, not a function.
          * ✅ Use `bot.heldItem` or `bot.heldItem?.name`
          * ❌ Do NOT write `bot.heldItem()`

    19) PARAMETER SEMANTIC CONVENTIONS - Avoid count parameter mismatches:
        - Skills have TWO different count semantics:
          * [ENSURE/target_total]: count = target total in inventory. If already have >= count, does NOTHING.
            e.g., `ensurePlanks(bot, 8)` = "make sure I have 8 total" (if have 4, crafts 4 more)
          * [DELTA]: count = additional amount to produce regardless of current inventory.
            e.g., `craftPlanks(bot, 4)` = "craft 4 NEW planks"
        - CRITICAL: Check parameter annotations in skill signatures ([ENSURE] vs [DELTA]).
          ❌ `ensurePlanks(bot, 4)` when you have 4 and need 8 → does nothing!
          ✅ `ensurePlanks(bot, 8)` → crafts 4 more to reach 8 total

    20) SKILL NAMING CONVENTIONS - Clear separation of quantity semantics and output types:

        QUANTITY SEMANTICS (how much):
        - mine*(count) / craft*(count) = DELTA - produce count ADDITIONAL items
        - ensure*(count) = TARGET_TOTAL - make sure inventory has count items total

        OUTPUT TYPES (what is produced):
        - mine* / craft* / ensure* = outputs ITEM to inventory
        - place* = outputs PLACED_BLOCK in world
        - setup* = outputs USABLE_BLOCK (placed + reachable functional block)

        CRITICAL RULES:
        - ensure* ALWAYS outputs items, NEVER places blocks (e.g., ensureCraftingTable(1) = 1 crafting_table ITEM)
        - setup* = FUNCTIONAL BLOCKS usable in world (e.g., setupCraftingTable(bot, maxDistance = 6))
          Steps: (1) check if block nearby, (2) call ensure* to get item if needed, (3) place it

        FUNCTIONAL_BLOCKS = [crafting_table, furnace, smoker, blast_furnace, anvil,
                            enchanting_table, brewing_stand, smithing_table, stonecutter, loom]

        IDEMPOTENCY REQUIREMENT: setup* must check bot.findBlock first; return immediately if block exists nearby.
        REUSABILITY REQUIREMENT: setup* must have at least one optional parameter beyond bot (e.g., maxDistance = 6). Use placeItem for placement.

    21) CRITICAL: FUNCTION NAME MUST MATCH IMPLEMENTATION LOGIC - Avoid semantic mismatch:

        NAMING CONVENTIONS AND REQUIRED IMPLEMENTATIONS:
        - mine*(bot, ...) - MUST contain actual mining logic: mineBlock(), bot.dig()
        - craft*(bot, ...) - MUST contain actual crafting logic: craftItem(), bot.craft()
        - smelt*(bot, ...) - MUST contain actual smelting logic: smeltItem(), bot.openFurnace()
        - ensure*(bot, count, ...) - MUST guarantee inventory has count items
        - setup*(bot, ...) - MUST guarantee a functional block is placed and usable
        - kill*(bot, ...) - MUST contain combat logic: killMob(), bot.attack()
        - place*(bot, ...) - MUST contain placement logic: placeItem(), bot.placeBlock()

        ❌ FORBIDDEN: `mineLogs(bot) {{ await ensureLogs(bot, count); }}` — name says "mine" but only delegates to "ensure"
        ✅ CORRECT: skill names starting with "mine" should actually call mineBlock internally

        Skill graph infers capabilities from function names. Semantic mismatch causes wrong skill selection.
