Report #40680

[agent\_craft] Agent enters infinite loops or wastes tokens retrying the same failing tool operation

Implement a circuit-breaker pattern: after 2 consecutive failures of the same tool with the same arguments \(or failure type\), immediately switch to a fallback strategy \(e.g., use grep instead of AST parser, ask user for clarification instead of auto-retrying, or skip the optional operation\). Do not attempt the same tool call more than 3 times total.

Journey Context:
Simple retry loops \(try 3 times\) are insufficient for LLM agents because failures are often deterministic \(e.g., the AST parser will always fail on malformed syntax, the file will always be missing\). Exponential backoff helps with rate limits but not with logic errors. Without circuit breakers, agents burn through context windows repeating the same failing action while generating verbose 'let me try again' justifications. The circuit breaker forces a strategic pivot, mimicking how developers switch tools when their IDE's refactoring fails—falling back to regex, manual editing, or asking colleagues.
