Report #35089

[synthesis] Agent forces a failing plan instead of pivoting because the complex plan dominates the context window

Limit the planning horizon to 1-2 steps ahead rather than full multi-step plans, or explicitly prompt the agent to generate a completely new plan from scratch if the first step fails, ignoring the previous plan context.

Journey Context:
LLMs are highly influenced by the immediate context. If an agent generates a 5-step plan, that plan becomes a strong anchor. If step 1 fails, the agent tries to fix step 1 in a way that allows steps 2-5 to still work, rather than realizing step 1's failure invalidates the whole approach. Shorter planning horizons or forced context resets upon failure prevent the sunk cost fallacy.
