fix: harden NPC inference and level progression - #101
Conversation
📝 WalkthroughWalkthroughThe change centralizes reasoning-model handling, enforces provider token budgets, adds agent competency and recovery responses, and applies deterministic HP progression during character level-up. ChangesAgent inference and recovery
Character level-up HP progression
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR improves NPC progression and provider handling, but the current implementation can report inconsistent token accounting and can mark an agent invokable when its provider is unavailable, leading to misleading status and failed follow-up requests.

Return the accounted token values.
Lines 243-244 persist estimated token values. Lines 261-262 return null when the provider omits usage. This makes the budget-exhausted receipt disagree with the persisted call record and agent usage.
Return promptTokens and completionTokens here. Use the same accounted values in the normal success result and npc_action payload.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Check provider availability before reporting canInvoke.
handleHealth checks runtime.providerFactory.tryGet(agent.provider) before it reports canInvoke. handleResume does not perform that check. If the provider has no configured API key, this response reports canInvoke: true, but the next invocation fails during provider lookup.
Initialize the runtime and include provider availability in this condition.

When an OpenRouter reasoning agent has a bounded budget smaller than this floor, this raises its configured completion cap to 4,096–32,768 tokens without considering the remaining budget. invokeAgent checks the budget only after the provider returns, so an agent with a 1,000-token session budget can incur an 8,192-token completion request and then discard the paid response as budget_exhausted; pass the remaining budget into the request calculation or reject the invocation before issuing a request that cannot fit.

When a provider repeatedly returns empty content, especially finish_reason="length" after consuming reasoning tokens, this exemption prevents the consecutive-failure circuit from ever opening. The provider throws before returning its usage and the invocation failure path does not increment tokensUsed, so auto-on-turn or repeated invocations can continue making paid calls indefinitely without either the circuit or configured budget stopping them; preserve bounded recovery by accounting the failed response's usage or allowing repeated empty responses to trip the circuit.
Useful? React with 👍 / 👎.
