[frontier] My agent gets stuck in loops or generates invalid tool sequences when plans fail

Integrate PDDL \(Planning Domain Definition Language\) or symbolic planners: use LLM to generate PDDL problems from natural language, run classical planner for deterministic plans, and use LLM to repair plans when execution fails.

Journey Context:
Pure LLM planning hallucinates invalid actions and can't backtrack efficiently. LLM\+P and similar approaches use LLMs to translate to PDDL, then use FastDownward or similar for optimal planning. When execution fails, the LLM updates the PDDL state and replans. Tradeoff: requires domain modeling, but eliminates hallucinated tool sequences. Emerging in 2025 as 'neuro-symbolic' planning.
