TAPE: Tool-Guided Adaptive Planning and Constrained Execution in Language Model Agents
Language Model (LM) agents excel in complex tasks but struggle under strict feasibility constraints, where a single error can lead to irrecoverable failure. This research introduces TAPE, a novel framework that significantly enhances LM agent reliability by mitigating both planning and sampling errors through adaptive planning with constrained execution.
Key Business Metrics & Strategic Impact
TAPE delivers robust improvements in AI agent performance, especially in high-stakes environments, directly translating into reduced operational risks and increased efficiency for enterprise applications.

The Problem: Irrecoverable Failures in LM Agents
Traditional ReAct frameworks for LM agents are highly susceptible to critical failures when operating under strict feasibility constraints. These failures stem primarily from two sources:
- Planning Error: The agent's internal reasoning generates a non-viable action, making the goal unachievable.
- Sampling Error: Stochastic token generation leads the LM to execute an action different from the planned one, even if the internal plan was correct.
These errors compound as tasks become longer and more complex, severely degrading success rates and making LM agents unreliable for real-world enterprise applications where mistakes are costly or irreversible.

TAPE's Solution: Adaptive Planning and Constrained Execution
TAPE (Tool-guided Adaptive Planning with constrained Execution) addresses the challenges of planning and sampling errors by integrating multiple strategies:
- Plan Graph Construction: Generates diverse candidate plans and aggregates them into a comprehensive plan graph.
- Planning Solver: Utilizes an external solver (e.g., Integer Linear Programming) to optimally select a feasible path from the graph, reducing planning errors.
- Constrained Execution: Employs constrained decoding to ensure the LM executes the planned action precisely, suppressing sampling errors.
- Adaptive Replanning: Dynamically re-plans when environmental feedback deviates from the expected state, ensuring robustness and adaptability.

Empirical Validation & Real-World Impact
Experiments across various benchmarks (Sokoban, ALFWorld, MuSiQue, GSM8K-Hard) demonstrate TAPE's consistent and significant outperformance over existing frameworks like ReAct and Plan-and-Act, especially in scenarios with strict feasibility constraints and higher task difficulty.
Key findings highlight TAPE's ability to reduce both planning and sampling errors, leading to substantial gains in success rates. This makes TAPE a critical advancement for deploying reliable LM agents in enterprise environments where failure is not an option.
| Framework | Planning Error (%)↓ | Sampling Error (%)↓ | Success Rate (%)↑ |
|---|---|---|---|
| ReAct | 50.7 ± 1.8 | 8.3 ± 1.0 | 5.0 ± 2.2 |
| Plan-and-Act | 47.7 ± 1.8 | 4.7 ± 0.8 | 17.0 ± 3.8 |
| TAPE | 36.7 ± 1.9 | 0.0 ± 0.0 | 46.0 ± 5.0 |
