+- `baseUrl: String` +- `apiVersion: String` +- `timeoutConfig: ConnectionTimeoutConfig` + +**Finding:** No cache-control fields.

The following are all absent: +1. No cache-control fields in `AnthropicClientSettings` +2. No cache parameters in `AnthropicLLMClient.execute()` +3. No cache-control builder in the Prompt DSL +4.

That harness has been **simplified over time, not extended** ([ZenML LLMOps DB write-up of David Hershey's MLOps podcast](https://www.zenml.io/llmops-database/building-and-deploying-a-pokemon-playing-llm-agent-at-anthropic)). Our V1 has more tools and no comparable memory or summarization layer — that explains most of the looping and re-discovery. Adding a knowledge-base tool plus accordion summarization is the highest-leverage V2 change. + +Second: **prompt caching with Anthropic gives 5-10× cost reduction on multi-turn agent loops** ([Anthropic docs](https://platform.claude.com/docs/en/build-with-claude/prompt-caching), [ProjectDiscovery write-up: 59-70% savings](https://projectdiscovery.io/blog/how-we-cut-llm-cost-with-prompt-caching)). V1 currently builds a fresh `AIAgent` and a fresh `AnthropicLLMClient` per outer turn — this *defeats* caching. Wiring caching properly (sliding-window breakpoints over turn history) plus a Voyager-style **skill library of reusable Kotlin/Koog tools** instead of asking the LLM to compose primitives every time, is the structural fix that makes the whole loop affordable. + +Third: **ReAct loops without external termination signals empirically diverge** on long-horizon, partially-observable tasks ([Reflexion paper, Shinn 2023](https://arxiv.org/abs/2303.11366); Anthropic's ZenML write-up notes Claude reaches Lt. Surge in ~35,000 actions vs ~26 hours for a human). V2 should not rely on the model to self-terminate the inner loop — it should use Koog's `singleRunStrategy()` (one tool call per LLM invocation, terminated by the runtime) and lift the outer reasoning back to our `AgentSession`, which already owns RAM-driven phase/watchdog detection. + +--- + +## 1.

Replace `reActStrategy` with `singleRunStrategy` + outer-loop ownership *(highest impact, medium effort)* + +Koog's `singleRunStrategy` makes one tool call per LLM invocation. Wrap it in our `AgentSession` outer loop, which already owns RAM-driven phase detection and the watchdog. Termination becomes deterministic: outer turn ends when (a) tool result returns, (b) phase changed, or (c) agent emitted plain text without a tool call. Eliminates the iteration-cap-as-default failure mode entirely. ([Koog](https://github.com/jetbrains/koog/blob/develop/docs/docs/nodes-and-components.md)) + +### 2.

Wire prompt caching properly *(high impact, medium effort)* + +Long-lived `AnthropicLLMClient`, cache breakpoints around: system prompt + tool descriptions (rarely change), knowledge base (changes per turn but we cache up to it), recent turn history (sliding). Should give 5-10× input cost reduction, dropping a Garland-attempt cost from $20-50 to single-digit dollars. ([Anthropic docs](https://platform.claude.com/docs/en/build-with-claude/prompt-caching)) + +### 4.

They become *single-tool-call-per-LLM-invocation* agents driven by `AgentSession`'s outer loop. + +## 4. Single-call inner loop + +### Why ReAct ran away in V1 + +ReAct ([Yao 2022, arXiv:2210.03629](https://arxiv.org/abs/2210.03629)) interleaves "Thought → Act → Observation" within a single LLM-driven loop. The strategy implementation in Koog ([`ai.koog.agents.ext.agent.reActStrategy`](https://github.com/JetBrains/koog/blob/develop/agents/agents-ext/src/commonMain/kotlin/ai/koog/agents/ext/agent/ReActStrategy.kt), see also the user-facing [predefined strategies doc](https://github.com/JetBrains/koog/blob/develop/docs/docs/predefined-agent-strategies.md)) keeps invoking the LLM on the same conversation until either: + +1. The LLM returns plain text without a tool call (the agent has "decided to stop"), or +2. The configured `maxIterations` is hit, in which case `AIAgentMaxNumberOfIterationsReachedException` is thrown. + +In V1 we observed the second branch every outer turn. Section 6 of [the original ReAct paper](https://arxiv.org/abs/2210.03629) and [Reflexion (Shinn 2023, arXiv:2303.11366)](https://arxiv.org/abs/2303.11366) §4.1 both note that ReAct without an external termination signal **diverges on long-horizon partially-observable tasks** — the model finds reasons to keep examining state instead of acting. This is exactly what we observed: the executor kept calling `getState` and producing analysis paragraphs ("goldLow=144 + goldMid×256 = 400 GP") instead of pressing buttons. + +### Switch to `singleRunStrategy` + +[Koog 0.5.1 ships `singleRunStrategy`](https://github.com/JetBrains/koog/blob/develop/docs/docs/predefined-agent-strategies.md#single-run-strategy). It does exactly one LLM call per `agent.run(input)`. If the LLM returns a tool call, Koog executes the tool and returns the tool's result as the agent's final output. If the LLM returns plain text, that text is the output. Either way: **one round-trip, deterministic termination**. + +This shifts ownership of the "outer ReAct loop" from Koog into our `AgentSession`. Our outer loop already had RAM-driven termination conditions (success criteria, party-defeated, budget). V2 adds: per-skill-invocation budget bump, sliding-window cache breakpoint refresh (§6), phase-transition watchdog. + +### Why this matters for cost + +Single-call inner means we pay for **one** LLM invocation per outer turn instead of up to 10. Combined with prompt caching (§6), V2's expected per-turn cost drops from ~$0.30-0.50 (V1 measured) to ~$0.02-0.05. + +### Outer loop shape (V2) + +``` +loop: + phase = observer.observe() + ram = observer.snapshot() + + outcome = SuccessCriteria.evaluate(phase) + if outcome != InProgress: terminate(outcome) + + if phase changed OR idleTurns >= IDLE_LIMIT: + advisor.consult(...) → currentPlan // single Koog call, may invoke getState/getScreen + idleTurns = 0 + + result = executor.invoke(buildInput(currentPlan, phase, ramDiff)) // single Koog call, single tool invocation + + trace.record(turn, phase, model, tokens, tool, result) + + newRam = observer.snapshot() + idleTurns = if (newRam ramEquivalent lastRam) idleTurns + 1 else 0 + skillsInvoked += if (result.invokedTool) 1 else 0 + costSoFar += result.tokens.estimatedCostUsd + + if (skillsInvoked >= SKILL_BUDGET || costSoFar >= COST_CAP || elapsed >= WALL_CLOCK_CAP): + terminate(OutOfBudget) +``` + +`ramEquivalent` is a custom comparator that ignores noisy fields like frame counter and PRNG state but checks `worldX/worldY/screenState/char[1..4]_status/enemyMainType/...`. + +### Code-level changes + +`ExecutorAgent.newAgent()`: + +```kotlin +private fun newAgent(phase: FfPhase): AIAgent = AIAgent( + promptExecutor = anthropicSession.executor, // long-lived, cache-aware + llmModel = modelRouter.modelFor(phase, AgentRole.EXECUTOR), + toolRegistry = registry, + strategy = singleRunStrategy(name = "ff1_executor"), // <-- was reActStrategy(1, name) + systemPrompt = ff1ExecutorSystemPrompt, +) +``` + +Same shape change in `AdvisorAgent`. Drop `maxIterations`. Drop our V1 `try/catch (AIAgentMaxNumberOfIterationsReachedException)` — it can't fire under `singleRunStrategy`. + +### Unit testability + +`singleRunStrategy` is more amenable to mocking than `reActStrategy`. We can inject a stub `PromptExecutor` returning a fixed tool call and assert that `executor.invoke(...)` produces the expected `EmulatorToolset` side effect. V2 plan adds `ExecutorAgentTest` and `AdvisorAgentTest` exercising this path with no live API calls. + +## 5. Skill library + +### Why skills + +[Voyager (NVIDIA, 2023, arXiv:2305.16291)](https://arxiv.org/abs/2305.16291) demonstrated that an LLM agent that builds and reuses a *skill library* — named, executable code units indexed by description — beats a vanilla ReAct agent by **15.3× on tech-tree progression** in Minecraft. The Voyager paper §3 frames skills as "an executable program containing all the actions necessary to complete a task," with the LLM acting as a "skill author and skill invoker." Hershey's [Claude Plays Pokémon harness](https://www.zenml.io/llmops-database/building-and-deploying-a-pokemon-playing-llm-agent-at-anthropic) embeds the same idea more conservatively: the `navigator` tool is a hand-coded skill that the LLM never has to re-derive. + +For FF1 V2 we hand-write the initial skill set (we don't yet need Voyager's automatic-skill-authoring layer; that's a V3+ idea). Each skill is **scripted Kotlin code** that drives the emulator deterministically. The LLM picks which skill to invoke; the skill's body costs zero LLM tokens. + +### Skill interface + +```kotlin +package knes.agent.skills + +import knes.agent.tools.results.StatusResult + +interface Skill { + val id: String + val description: String // surfaced as the @LLMDescription text + suspend fun invoke(args: Map = emptyMap()): SkillResult +} + +data class SkillResult( + val ok: Boolean, + val message: String, + val framesElapsed: Int = 0, + val ramAfter: Map = emptyMap(), +) +``` + +Skills are registered into `SkillRegistry`, a `ToolSet` whose `@Tool`-annotated methods the LLM sees. The skill registry lazily binds to the live `EmulatorToolset` so skills can drive the emulator without piping references around. + +### `pressStartUntilOverworld(maxAttempts: Int = 60): SkillResult` + +**Goal:** advance from the title screen / menu through NEW GAME until `bootFlag == 0x4D` (the in-game indicator from `knes-debug/src/main/resources/profiles/ff1.json`, line 28). + +**Strategy:** tap START with a 30-frame gap; check RAM after each tap; if `bootFlag` flipped, return success; otherwise repeat up to `maxAttempts`. + +**Sketch:** + +```kotlin +class PressStartUntilOverworld(private val toolset: EmulatorToolset) : Skill { + override val id = "press_start_until_overworld" + override val description = "Tap START until the game leaves the title/menu state and reaches in-game (FF1 bootFlag = 0x4D). Bounded by maxAttempts." + + override suspend fun invoke(args: Map): SkillResult { + val maxAttempts = args["maxAttempts"]?.toIntOrNull() ?: 60 + var attempts = 0 + var totalFrames = 0 + while (attempts < maxAttempts) { + val tap = toolset.tap("START", count = 1, pressFrames = 5, gapFrames = 30) + totalFrames += tap.frame + attempts++ + val state = toolset.getState() + if (state.ram["bootFlag"] == 0x4D) { + return SkillResult(ok = true, message = "Reached in-game after $attempts taps", framesElapsed = totalFrames, ramAfter = state.ram) + } + } + return SkillResult(ok = false, message = "bootFlag never flipped after $maxAttempts START taps", framesElapsed = totalFrames) + } +} +``` + +**Edge cases:** intro cinematic (sometimes needs A/B presses, not just START); we handle by tapping `START` first and only if 10 attempts pass without progress, falling back to `A`. Speedrun community calls this the [intro skip pattern](https://www.speedrun.com/final_fantasy_nes/guides/vk3vf). + +### `createDefaultParty(classes: List, names: List?): SkillResult` + +**Goal:** complete character creation: pick 4 classes, name each character, confirm. + +**FF1 class indices** (from FF1 disassembly community; see [datacrystal.tcrf.net FF1 NES](https://datacrystal.tcrf.net/wiki/Final_Fantasy_(NES)) and the GameFAQs class table): + +``` +0 = Fighter (FIGHTER) +1 = Thief (THIEF) +2 = Black Belt (BLACK_BELT) +3 = Red Mage (RED_MAGE) +4 = White Mage (WHITE_MAGE) +5 = Black Mage (BLACK_MAGE) +``` + +**Strategy** (sequential, no branching needed): + +1. From overworld-after-NewGame menu: navigate to `New Game` confirm. (handled by `pressStartUntilOverworld` already if it lands here, but if it lands one screen earlier we add the second tap.) +2. For each of the 4 character slots: + 1. Use UP/DOWN to position cursor at desired class (read `menuCursor` to confirm position). + 2. Press A to select class. + 3. Use UP/DOWN/LEFT/RIGHT in name-entry grid to spell the name (default: "H1"–"H4" — short to keep this fast). Press A on each letter, then on END. + 4. Confirm class+name (A). +3. After fourth character, confirm whole party (A on the YES button). + +**Termination check:** all four `char[1..4]_status` values transition from 0xFF (uninitialized) to 0x00 (alive, no status). Ramdump signature confirms party exists in RAM ([TASvideos FF1 RAM map](https://tasvideos.org/GameResources/NES/FinalFantasy1)). + +**Default classes:** `["FIGHTER", "FIGHTER", "WHITE_MAGE", "BLACK_MAGE"]` — solid balanced party for early game per the [GameFAQs class guide](https://gamefaqs.gamespot.com/nes/522595-final-fantasy/faqs/3290). + +**Implementation note:** the name-entry grid layout is a fixed 6×6 (or so) grid of letters; we hardcode the screen-coordinate-to-letter mapping. Documented at [strategywiki.org/wiki/Final_Fantasy/Walkthrough](https://strategywiki.org/wiki/Final_Fantasy/Walkthrough). + +### `walkOverworldTo(targetX: Int, targetY: Int, maxSteps: Int = 200): SkillResult` + +**Goal:** BFS-pathfind from current `(worldX, worldY)` to target tile. + +**Walkable tile data:** FF1 overworld is a 256×256 tile map. The walkable-vs-blocked classification comes from the world map's tile type table at ROM offset `0x40000` (per the [FF1 disassembly](https://github.com/SubtleAlchemist/ff1-disasm)). We extract this once into a `walkableTiles: Set` constant. + +Alternative if ROM extraction proves brittle: hardcode the **path** from Coneria castle exit to the bridge tile (it's a single fixed sequence of ~40 tiles, well-documented in any [speedrun route](https://www.speedrun.com/final_fantasy_nes/guides/vk3vf)). For V2 hardcoded path is simpler and probably sufficient for goal scope C. + +**Sketch (path-based variant):** + +```kotlin +class WalkOverworldTo(private val toolset: EmulatorToolset) : Skill { + override val id = "walk_overworld_to" + override val description = "Walk overworld from current (worldX, worldY) toward (targetX, targetY).

Aborts on encounter (screenState=0x68)." + + private val FRAMES_PER_TILE = 16 // FF1 walking speed; confirmed in TASvideos guide + + override suspend fun invoke(args: Map): SkillResult { + val tx = args.getValue("targetX").toInt() + val ty = args.getValue("targetY").toInt() + val maxSteps = args["maxSteps"]?.toIntOrNull() ?: 200 + var stepsTaken = 0 + while (stepsTaken < maxSteps) { + val state = toolset.getState() + val ram = state.ram + if (ram["screenState"] == 0x68) { + // Encounter triggered — that's a normal exit for this skill. + return SkillResult(ok = true, message = "Encounter triggered after $stepsTaken steps", ramAfter = ram) + } + val cx = ram["worldX"] ?: return SkillResult(false, "worldX missing") + val cy = ram["worldY"] ?: return SkillResult(false, "worldY missing") + if (cx == tx && cy == ty) { + return SkillResult(true, "Reached ($tx, $ty) in $stepsTaken steps", ramAfter = ram) + } + val dir = pickDirection(cx, cy, tx, ty) + toolset.step(buttons = listOf(dir), frames = FRAMES_PER_TILE) + stepsTaken++ + } + return SkillResult(false, "Did not reach ($tx, $ty) in $maxSteps steps") + } + + private fun pickDirection(cx: Int, cy: Int, tx: Int, ty: Int): String = when { + tx > cx -> "RIGHT"; tx < cx -> "LEFT"; ty > cy -> "DOWN"; else -> "UP" + } +} +``` + +For V2 scope C the only `walkOverworldTo` invocation we need is "to the bridge tile" — likely `(0xC4, 0x96)` or thereabouts; we'll confirm during implementation. Hardcoded plan if BFS proves unreliable: a list of `(direction, tile-count)` pairs the skill executes. + +### Re-exposed existing actions via skill registry + +`BattleFightAll` and `WalkUntilEncounter` already exist in `knes-debug/src/main/kotlin/knes/debug/actions/ff1/` and are registered through `ActionRegistry`. The skill registry surfaces them as Koog `@Tool` methods alongside the new skills, so the LLM sees one uniform "what skills can I invoke" list. Implementation: `SkillRegistry` constructor wraps each registered `GameAction` for the active profile in a synthetic `Skill` that delegates to `EmulatorToolset.executeAction(profileId, actionId)`. + +### Skill registry: what Koog actually sees + +`SkillRegistry : ToolSet` exposes exactly these methods (each annotated `@Tool` + `@LLMDescription`): + +``` +pressStartUntilOverworld(maxAttempts: Int = 60): SkillResult +createDefaultParty(classes: List = …, names: List? = null): SkillResult +walkOverworldTo(targetX: Int, targetY: Int, maxSteps: Int = 200): SkillResult +battleFightAll(): ActionToolResult // delegates to GameAction +walkUntilEncounter(): ActionToolResult // delegates to GameAction +getState(): StateSnapshot // unchanged from V1 +askAdvisor(reason: String): String // unchanged from V1, lives on advisor side +``` + +Seven tools. Down from V1's 13. Raw `step / tap / sequence / press / release / loadRom / reset / applyProfile` remain on `EmulatorToolset` (used by skills internally + by the Ktor / MCP layers for Claude Code) but are **not** registered with Koog. + +### Skills as path to V3 ("scope C") + +In V3 we collapse all skill methods into a single `invokeSkill(name: String, args: Map)` tool, dropping the per-skill `@Tool` methods. The skill registry stays intact; only the Koog-visible facade collapses. That brings tool count to 3 (`invokeSkill`, `getState`, `askAdvisor`) — Hershey-equivalent. We don't do this in V2 because typed signatures help the LLM pick the right skill while we're still tuning the set. Once skills stabilize, the typed surface stops earning its keep. + +## 6. Prompt caching + +### Why this matters + +[Anthropic prompt caching](https://platform.claude.com/docs/en/build-with-claude/prompt-caching) (also documented at [docs.anthropic.com/en/docs/build-with-claude/prompt-caching](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching)) lets you mark prefix portions of a prompt as cacheable. Cached prefix tokens are charged at **10% of base input price** ([Anthropic pricing](https://platform.claude.com/docs/en/build-with-claude/prompt-caching#pricing)) and can be reused for **5 minutes** by default. ProjectDiscovery reports [59-70% input-cost reduction](https://projectdiscovery.io/blog/how-we-cut-llm-cost-with-prompt-caching) on multi-turn tool-using agents; a [related industry write-up](https://www.helicone.ai/blog/prompt-caching) sees similar 5-10× compounding savings on agent loops. + +V1 builds a fresh `AnthropicLLMClient` per outer turn (we did this in V1 Task 6.1 to dodge `400 messages: final assistant content cannot end with trailing whitespace` errors that came from `reActStrategy` reusing conversation state). This **completely defeats caching** — every call is a cold prompt. + +### V2 caching architecture + +``` +[ system prompt + tool descriptions ] ← cache_control: ephemeral; ~1500-2500 tokens, hit rate ~99% +[ "static run preamble" ← cache_control: ephemeral; ~400 tokens, hit rate ~90% + - rom name, profile, goal (refreshed only when phase class changes) + - active phase classification ] +[ "rolling state preamble" ← uncached; ~150 tokens + - RAM diff since last turn + - last skill result + - current advisor plan ] +[ "this turn input" ← uncached; ~50 tokens + - "What is the next skill to invoke?" ] +``` + +Cache breakpoints (Anthropic supports up to 4 per request): + +1. **End of system prompt** — biggest win. System prompt + 7 `@Tool` descriptions are static across the whole run. Caches the most expensive tokens. +2. **End of static run preamble** — caches the "what game, what phase" framing across consecutive turns in the same phase. Refreshed when phase class transitions (advisor consultation point anyway). +3. *(reserved for V3)* End of accordion summary — caches the long-term-memory digest. +4. *(reserved for V3)* End of recent-turn history window. + +V2 uses breakpoints 1 and 2. V3 fills in 3 and 4 once we add summarization. + +### Implementation + +`AnthropicSession` (new file `knes-agent/src/main/kotlin/knes/agent/llm/AnthropicSession.kt`): + +```kotlin +package knes.agent.llm + +import ai.koog.prompt.executor.clients.anthropic.AnthropicLLMClient +import ai.koog.prompt.executor.clients.anthropic.AnthropicLLMClientSettings +import ai.koog.prompt.executor.llms.SingleLLMPromptExecutor + +class AnthropicSession(apiKey: String) : AutoCloseable { + // Single long-lived client; cache headers travel with each request. + val client: AnthropicLLMClient = AnthropicLLMClient( + apiKey = apiKey, + settings = AnthropicLLMClientSettings( + // Enable extended cache control headers if Koog 0.5.1 exposes them. + // If not, we drop down to AnthropicAPI directly per §11 risk note. + ), + ) + val executor: SingleLLMPromptExecutor = SingleLLMPromptExecutor(client) + + override fun close() { + // Koog client uses Ktor's CIO; release coroutine resources. + } +} +``` + +`PromptCacheConfig` (new file) holds the cache-breakpoint markers used when assembling each turn's prompt. Implementation depends on what Koog 0.5.1's `Prompt` builder exposes — first task of the plan probes this and falls back to direct Anthropic SDK if Koog's wrapper doesn't expose `cache_control` per-message-block. + +### What V1 wasted + +V1 measured cost (rough): ~$0.30 per outer turn at 50% of cap = ~$0.60 actual; 5 turns observed in the 9-minute run before timeout; extrapolated to ~50-200 turns for a Garland run gives $30-120 worst case. With caching at typical 60-80% hit rate on the system+tool prefix and skill library cutting the per-turn input from ~3000 to ~1000 tokens (because the agent isn't enumerating button-level tools every turn), V2 target is ≤ $0.05 per outer turn → ≤ $3 per Garland run. + +`AnthropicSession` lives for the whole `AgentSession.run()`. `ExecutorAgent` and `AdvisorAgent` constructors take it as a dependency (instead of `apiKey: String` as in V1). Both share the same client, so cache breakpoints they place hit each other's lookups. + +## 7. Model routing + +### Pricing snapshot (per [Anthropic pricing page](https://platform.claude.com/docs/en/about-claude/pricing), 2026-05) + +| Model | Input $/MTok | Output $/MTok | Cached input $/MTok | Speed | +|---|---|---|---|---| +| Haiku 4.5 | $1 | $5 | $0.10 | fastest | +| Sonnet 4.5 | $3 | $15 | $0.30 | medium | +| Opus 4 / 4.1 | $15 | $75 | $1.50 | slowest | + +Haiku 4.5 is **15× cheaper than Opus on input** and **15× cheaper on output**.

Lives at `knes-agent/src/main/kotlin/knes/agent/llm/ModelRouter.kt`. + +The `ExecutorAgent` and `AdvisorAgent` constructors take a `ModelRouter` and call `modelRouter.modelFor(currentPhase, role)` at each `newAgent(phase)` invocation. Since `singleRunStrategy` agents are constructed per-call (cheap), routing per-call is essentially free. + +### Measurement + +V2 trace logs will record (per turn): model used, tokens in, tokens out, cache-hit-tokens, derived USD cost. This data lets us tune the routing table empirically after the first few real runs — e.g., if Haiku 4.5 picks the wrong skill in `Overworld` more than X% of the time, bump `Overworld` executor to Sonnet 4.5. + +## 8. New phase classifications + +`RamObserver` adds: + +- `NewGameMenu` — `bootFlag != 0x4D` AND `screenState == something_specific` (we'll need to observe and document the constant during V2 implementation; see §11 Risks). +- `NameEntry` — character creation; identified by RAM markers from `ff1.json` (likely `menuCursor` + `screenState` combination). + +The bootFlag-based `TitleOrMenu` from V1 stays as the catch-all for "pre-game with no more specific signal." + +These new phases let advisor and executor produce phase-specific plans without re-deriving game state from screenshots every turn. + +## 9. New `Outcome.AtGarlandBattle` + +```kotlin +enum class Outcome { InProgress, AtGarlandBattle, Victory, PartyDefeated, OutOfBudget, Error } +``` + +`SuccessCriteria.evaluate(phase)`: + +- `Battle(enemyId = GARLAND_ID, enemyDead = false)` → `AtGarlandBattle` (V2 acceptance) +- `Battle(enemyId = GARLAND_ID, enemyDead = true)` → `Victory` (V3 acceptance, same constant kept for forward-compat) +- `PartyDefeated` → `PartyDefeated` +- everything else → `InProgress` + +`AgentSession.run()` returns `AtGarlandBattle` and exits.

Cost and time budgets + +V2 budgets (CLI flags, defaults): + +- `--max-skill-invocations=80` (skills are macro; 80 should suffice for boot→Garland based on speedrun routes). +- `--cost-cap-usd=3` — derived from `tokensIn × $0.003/1k + tokensOut × $0.015/1k` (Sonnet 4.5 prices) with caching modeled. Conservative; abort if exceeded. +- `--wall-clock-cap-seconds=900` (15 min). + +Each tracked in `AgentSession`. Exceeding any cap returns `OutOfBudget`. + +## 11. Risks and open questions + +- **`NewGameMenu` / `NameEntry` RAM signatures.** `ff1.json` documents `screenState`, `menuCursor`, and `bootFlag`, but the exact value combinations for these phases need empirical confirmation during implementation. Plan task: write a small `RamRecorder` that runs the emulator under manual input and logs RAM snapshots at each visual phase, so we can encode the constants from real data instead of guessing. +- **Skill robustness across ROM regions.** `BattleFightAll`, `WalkUntilEncounter`, and our scripted name-entry assume USA / English ROM. PAL/JP would break menu indices. V2 explicitly assumes the standard NES USA ROM. +- **Walkable-tile table for `walkOverworldTo`.** FF1 overworld tile data lives in ROM at known addresses; we hardcode the walkable IDs. Wrong table = walking through ocean. Verify against TASvideos resources during implementation. +- **`singleRunStrategy` may not exist by that exact name in Koog 0.5.1.** Research cites `nodes-and-components.md`. Confirm by jar inspection in the very first plan task; rename if needed. +- **Prompt caching coverage in Koog.** Koog 0.5.1 may or may not expose Anthropic cache breakpoints declaratively. Worst case we configure them at the `AnthropicLLMClient` level and bypass Koog's wrapper. Plan task: probe the API; fall back to direct Anthropic SDK call if Koog lacks support. +- **Determinism of skills under shared mode.** Skills currently target `EmulatorSession()` standalone. If anyone runs the agent in shared mode (with the Compose UI driving frames), skills must not deadlock. The mode-aware `step/tap/sequence` from V1 already handles this — skills inherit it. +- **Garland enemy id (`GARLAND_ID = 0x7C`).** Same uncertainty as V1 — confirm on first observed bridge battle. If wrong, V2 fails to detect `AtGarlandBattle` and runs out of budget. + +## 12. Path to V3 ("scope C" of research) + +V2 deliberately doesn't try to land all five research recommendations at once. The remaining items become V2.x / V3 increments. Each is contained, shippable on its own, and depends only on V2's seams: + +### V2.1 — Accordion summarization + +Why: research §1, §3, §4 — Hershey's harness compresses every ~30 actions into a digest while preserving the knowledge base verbatim ([ZenML write-up](https://www.zenml.io/llmops-database/building-and-deploying-a-pokemon-playing-llm-agent-at-anthropic)). Without this, multi-hour runs blow out the 200k context window. + +Hook: `AgentSession.run()` after every N turns invokes a "summarize the last N turns into 200 words" LLM call (Sonnet, cheap). Existing `Trace` already holds the data. New file: `knes-agent/src/main/kotlin/knes/agent/runtime/Summarizer.kt`. Doesn't change V2 architecture. + +Effort: small. Marginal impact for V2's scope (boot→Garland is short enough not to need it), big impact for V3 (winning Garland) and beyond. + +Reference: Koog's [`nodeLLMCompressHistory`](https://github.com/JetBrains/koog/blob/develop/agents/agents-core/src/commonMain/kotlin/ai/koog/agents/core/agent/entity/SystemNodes.kt) does exactly this declaratively if we want to lift the loop into a Koog strategy graph — see [docs/docs/agents/graph-based-agents.md](https://github.com/JetBrains/koog/blob/develop/docs/docs/agents/graph-based-agents.md). + +### V2.2 — `LongTermMemory` with FF1 `Concept`s + +Why: Hershey's `update_knowledge_base` tool gives the LLM explicit memory it can edit. Koog 0.5.1 has [`LongTermMemory`](https://github.com/JetBrains/koog/blob/develop/agents/agents-features/agents-features-longterm-memory/Module.md) that exposes the same pattern declaratively. + +Concepts to capture for FF1: `currentObjective`, `gameProgress`, `partyComposition`, `keyItems`, `recentFailures`, `discoveredLocations`. Each has a `FactType` (single-value, list, map). The LLM gets a `recordFact(concept, value)` and `recallFacts(concept)` tool pair instead of stuffing knowledge into prompt history. + +Reference: [Module.md](https://github.com/JetBrains/koog/blob/develop/agents/agents-features/agents-features-longterm-memory/Module.md), [Hershey deep-dive](https://michaelyliu6.github.io/posts/claude-plays-pokemon/) on KB design. + +### V2.3 — Tool surface reduction to 3 ("Hershey configuration") + +Collapse the 7 V2-Koog-visible tools into 3: + +``` +invokeSkill(name: String, args: Map): SkillResult +recordFact(concept: String, value: String): StatusResult +askAdvisor(reason: String): String +``` + +Plus the implicit `getState`-via-skill-result (every skill result includes `ramAfter`, so explicit `getState` becomes redundant). + +The skill registry remains intact; this is a Koog-facing facade swap. Once the skill set has stabilized through real runs, typed signatures buy less than narrow tool count saves in iteration cost (Hershey: "stripped out complexity over time"). We don't do this in V2 because we're still discovering which skills matter. + +Code change: replace `SkillRegistry`'s `@Tool`-annotated methods with a single `@Tool fun invokeSkill(...)` that internally dispatches on `name`. ~50 LOC. + +### V2.4 — Reflexion self-criticism on watchdog escalation + +Why: research §3 cites Reflexion ([Shinn 2023, arXiv:2303.11366](https://arxiv.org/abs/2303.11366)) for long-horizon agents. Hershey's secondary-LLM KB review is the same idea. + +Hook: when `AgentSession`'s `idleTurns >= IDLE_LIMIT` (already detected in V1), instead of just re-prompting the advisor with the latest observation, prepend a "reflect on what went wrong in the last N turns" turn first. The advisor's output is one paragraph of self-criticism that gets injected into the executor's next prompt. + +This is Reflexion's "verbal reinforcement" applied to our existing escalation point. ~30 LOC in `AgentSession`. + +### V2.5 — Voyager-style automatic skill authoring (V3+) + +Why: Voyager's killer feature is the LLM **writing new skills** when current ones fail. We could do the same: when a `walkOverworldTo` invocation fails, the advisor proposes a Kotlin code snippet that becomes a new `Skill`, gets compiled, and added to the registry. + +Out of scope for V2/V2.x. Listed for completeness because the skill registry abstraction is the prerequisite — V2's `Skill` interface is sufficient as a mounting point. + +Reference: [Voyager paper §3.2](https://arxiv.org/abs/2305.16291), specifically the iterative-prompting + self-verification loop.

V2.5 only after V2.4 demonstrably saves runs that V2 lost. + +Each step is its own brainstorm-spec-plan-execute cycle. Each is shippable.

Input is injected through `ControllerProvider`, the same interface used by the keyboard and gamepad controllers. + +``` +HTTP Client (AI agent / TAS tool / script) + | + v +ApiServer (Ktor routes) + | + v +EmulatorSession (NES lifecycle) + | + v +ApiController implements ControllerProvider + | + v +NES <-- reads button state via getKeyState() during emulation +``` + +### Key Components + +- **`ApiController`** — Implements `ControllerProvider` (same interface as `KeyboardController` and `GamepadController`). The NES polls `getKeyState()` during emulation — it doesn't know or care that the inputs come from HTTP requests. +- **`EmulatorSession`** — Headless NES wrapper. Runs the CPU synchronously via `cpu.step()` with frame counting through the PPU's `imageReady` callback. Same proven pattern as the E2E test harness. +- **`ApiServer`** — Ktor routes that translate HTTP requests into `EmulatorSession` operations. + +### Execution Model + +The emulator runs **synchronously** — `POST /step` blocks until the requested frames have been rendered. This is intentional: +- Deterministic: same inputs always produce the same outputs +- No race conditions between HTTP requests and emulation +- Agent can reason about exact frame counts +- Same approach used by Gymnasium/Stable-Retro + +--- + +## Inspiration & Alternatives + +### Why a REST API? + +The goal was to make the emulator controllable by **any client** — AI agents (Python, JS, Go), TAS tools, web dashboards, LLM tool-use, or simple curl scripts. REST is the lowest common denominator: every language has an HTTP client. + +### Considered Alternatives + +| Approach | Why Not Chosen | +|----------|---------------| +| **Python binding (gym-retro style)** | Requires Python + native bindings. kNES is JVM-native — a REST API is more natural and language-agnostic. | +| **gRPC** | Better performance for high-frequency agents, but adds protobuf complexity and tooling. REST is sufficient for 60fps frame stepping. Can be added later if needed. | +| **WebSocket streaming** | Good for real-time observation but adds state management complexity. The synchronous step model is simpler and sufficient for most agents. Could be added as a complementary channel. | +| **Direct JVM library** | Lowest latency, but locks clients to JVM. The `EmulatorSession` class can still be used directly from Kotlin/Java without the HTTP layer. | +| **Embedded in Compose UI** | Would couple the API to the desktop app. Separate module keeps concerns clean — the API server is headless by design. | + +### Prior Art + +- **[OpenAI Gym Retro](https://github.com/openai/retro) / [Stable-Retro](https://stable-retro.farama.org/)** — Python library wrapping Libretro emulators with `env.step(action) → observation`. Our `POST /step` follows the same pattern over HTTP. +- **[NousResearch/pokemon-agent](https://github.com/NousResearch/pokemon-agent)** — FastAPI server wrapping PyBoy with `/action`, `/state`, `/screenshot` endpoints. Direct inspiration for our endpoint design. +- **[FCEUX FM2 format](https://fceux.com/web/FM2.html)** — The de facto standard for NES TAS input recording. Our `/fm2` endpoint accepts this format directly. +- **[Gymnasium API](https://gymnasium.farama.org/)** — The standard RL environment interface. Our step-based model mirrors `env.step(action)`. + +### Why Ktor? + +- **Kotlin-native** — same language as the rest of kNES, same JetBrains ecosystem +- **Embedded** — no external server needed, starts in milliseconds +- **Lightweight** — Netty engine, ~5MB dependency footprint +- **Test-friendly** — `testApplication` API for in-process HTTP testing without starting a real server diff --git

One significant limitation was the addressable memory space of the 6502 CPU used in the NES, which could only directly address 64KB of memory. However, many NES games required more memory than this limit, especially as games became more complex over the console's lifespan. + +To overcome this limitation, NES cartridges implemented a technique called "memory mapping" or "bank switching." This technique allowed games to use more memory than the CPU could directly address by dynamically swapping different "banks" of memory into the CPU's addressable space. + +## What is a Mapper? + +In the context of NES emulation, a "mapper" is a hardware component inside the game cartridge that controls how memory is mapped between the cartridge and the console. Each mapper implements a specific bank-switching scheme, determining how ROM and RAM are accessed by the CPU and PPU (Picture Processing Unit). + +The mapper sits between the game's ROM/RAM and the console's CPU/PPU, translating memory accesses and potentially modifying them based on its internal state. This allows games to: + +1. Use more program code (PRG-ROM) than the CPU can directly address +2. Use more graphical data (CHR-ROM) than the PPU can directly address +3. Implement special hardware features not natively supported by the NES + +## Why Different Games Used Different Mappers + +Game developers created different mapper designs to meet various requirements: + +1. **Memory Size Requirements**: As games grew larger and more complex, they needed more sophisticated memory management. +2. **Cost Considerations**: Simpler mappers were cheaper to manufacture, so games with modest requirements used simpler mappers. +3. **Special Hardware Features**: Some games needed special features like additional sound channels, IRQ (Interrupt Request) timers, or SRAM (Static RAM) for save data. +4. **Different Manufacturers**: Different companies developed their own mapper designs optimized for their specific needs. + +## Examples of Different Mapper Types + +1. **Mapper 0 (NROM)**: The simplest mapper with no bank switching, used for small games like Super Mario Bros. +2. **Mapper 1 (MMC1)**: A common mapper that supports PRG-ROM and CHR-ROM banking, used in games like The Legend of Zelda. +3. **Mapper 2 (UNROM)**: A simple mapper that only switches PRG-ROM banks, used in games like Mega Man. +4. **Mapper 4 (MMC3)**: A sophisticated mapper with IRQ capabilities, used in games like Super Mario Bros. 3. +5. **Mapper 7 (AxROM)**: A simple mapper with a single switchable PRG-ROM bank and single-screen mirroring. + +Each mapper implementation in the kNES codebase extends the `MapperDefault` class and overrides specific methods to implement its unique memory mapping scheme. + +## How Mappers are Selected in kNES + +In the kNES emulator, the appropriate mapper is selected based on information in the ROM header: + +1. When a ROM is loaded, the emulator reads the mapper type from the ROM header (bytes 6 and 7). +2. The `ROM.createMapper()` method creates an instance of the appropriate mapper class based on this type. +3. The mapper is then initialized with the ROM data and connected to the emulated NES system. + +If a ROM uses a mapper that isn't supported by the emulator, the game won't run correctly or at all. + +## Why Emulators Need Multiple Mapper Implementations + +An knes.emulator.NES emulator needs to implement multiple mappers for several reasons: + +1. **Game Compatibility**: To support a wide range of NES games, an emulator must implement all the mapper types used by those games. +2. **Accurate Emulation**: Different mappers behave differently, and accurate emulation requires implementing these differences. +3. **Special Features**: Some games rely on special mapper features for gameplay mechanics, sound, or graphics. + +Without the correct mapper implementation, a game might: +- Fail to load +- Display corrupted graphics +- Have incorrect behavior +- Crash at certain points + +## Conclusion + +The need for multiple mappers in NES emulation stems from the hardware diversity of original NES cartridges. Game developers created various mapper designs to overcome the memory limitations of the NES and implement special features. To accurately emulate these games, an emulator must implement all these different mapper types. + +The kNES emulator demonstrates this by implementing over 30 different mapper types, each with its own memory mapping scheme and special features. This allows the emulator to support a wide range of NES games, from simple games using the basic NROM mapper to complex games using sophisticated mappers like MMC3 or MMC5. + +Understanding the role of mappers is crucial for NES emulation, as they represent a significant part of what made each NES game unique from a hardware perspective. \ No newline at end of file diff --git a/knes-emulator/src/main/kotlin/knes/emulator/memory/MemoryAccess.kt b/knes-emulator/src/main/kotlin/knes/emulator/memory/MemoryAccess.kt new file mode 100644 index 00000000..96101a30 --- /dev/null +++ b/knes-emulator/src/main/kotlin/knes/emulator/memory/MemoryAccess.kt @@ -0,0 +1,24 @@ +/* + * + * * Copyright (C) 2025 Artur Skowroński + * * This file is part of kNES, a fork of vNES (GPLv3) rewritten in Kotlin. + * * + * * vNES was originally developed by Brian F.
