[agent\_craft] Agent enters infinite loop or burns budget retrying the same failing tool call

Implement an error budget \(max 2 retries per tool\); after first failure, force a 'reflection' step where the agent must analyze the error and modify strategy before second attempt; hard stop after budget exhausted.

Journey Context:
The naive retry loop—'if tool fails, call it again with same args'—is a common failure mode when the error is semantic \(e.g., file not found because the agent hallucinated the path\) rather than transient \(network blip\). Without a circuit breaker, the agent will burn through token budgets and API rate limits repeating the same mistake. The ReAct framework introduced the 'thought' step, but the specific hardening is the 'error budget' pattern. After any tool exception or non-zero exit code, check a retry counter. If <1, trigger a 'reflection' prompt: 'The previous action failed with error X. Before retrying, analyze what went wrong and propose a corrected approach.' This forces the model to change the input parameters or select a different tool. If the second attempt fails, do not retry; return a failure status to the parent orchestrator or user. This prevents the 'stuck agent' scenario. The common mistake is implementing exponential backoff without semantic reflection—backoff helps with rate limits, not with hallucinated arguments.
