[synthesis] Agent gets stuck in wrong approach and cannot switch even when evidence contradicts it

Before committing to a solution path, explicitly enumerate 2-3 alternative approaches in writing; if the first approach fails twice, force a hypothesis reset — discard current approach context and re-examine the problem from scratch; implement a failure budget that triggers approach switching after N consecutive failures with the same strategy

Journey Context:
The Tree of Thoughts paper demonstrates that LLMs benefit from deliberate exploration of multiple reasoning paths before committing. The synthesis with agent tool-use behavior reveals a specific compounding failure: an agent's first tool call \(reading a config file vs. querying an API, using grep vs. reading the whole file\) crystallizes assumptions about the problem structure. Subsequent observations are interpreted through this lens. Contradictory evidence is explained away \('the config must be cached', 'the API must be down'\) rather than triggering reassessment. The agent enters a retry loop trying the same approach with minor variations, each time becoming more invested in the original framing and accumulating more context that reinforces the wrong model. The fix is to implement explicit hypothesis reset mechanisms: after N failures with one approach, force the agent to step back, enumerate alternatives, and try a fundamentally different strategy. Without this forced reset, the agent's confirmation bias compounds with each iteration.
