Self-CriTeach: LLM Self-Teaching and Self-Critiquing for Improving Robotic Planning via Automated Domain Generation
Pith reviewed 2026-05-18 13:26 UTC · model grok-4.3
The pith
An LLM can bootstrap stronger robotic planning by generating its own symbolic domains for training data and rewards.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The central claim is that LLM-generated symbolic planning domains can play a dual role: they supply the data for producing extended CoT trajectories that fine-tune the model on planning, and they supply dense, structured reward signals that train the model via reinforcement learning. This unified pipeline produces a planning-enhanced LLM that achieves higher success rates, stronger cross-task generalization, reduced inference cost, and improved resistance to imperfect logical states.
What carries the argument
The Self-CriTeach pipeline, where autonomously generated symbolic planning domains are reused both to derive extended CoT supervision for fine-tuning and to define structured reward functions for reinforcement learning.
If this is right
- Planning success rates rise on standard robotic tasks.
- Cross-task generalization strengthens without task-specific human data.
- Inference cost drops because the model plans more efficiently.
- Performance holds up better when logical states are incomplete or noisy.
Where Pith is reading between the lines
- The method could support repeated self-improvement cycles in which each round of generated domains refines the model further.
- The same dual-use pattern might apply to planning problems outside robotics, such as logistics or scheduling.
- By removing manual reward engineering, the approach could make reinforcement learning more practical for complex real-world robot tasks.
Load-bearing premise
The symbolic planning domains generated by the LLM must be accurate enough to produce reliable training trajectories and effective reward signals.
What would settle it
A controlled test measuring whether the resulting LLM still outperforms baselines on robotic tasks when the input states contain simulated logical errors or perception noise.

read the original abstract
Large Language Models (LLMs) have shown strong promise for robotic task planning, particularly through the automatic generation of symbolic planning domains. However, prior work mainly treats generated domains as planning utilities. Such pipelines remain brittle under imperfect logical states and perception noise, while overlooking the potential of generated domains as scalable sources of reasoning supervision and structured reward signals. At the same time, reasoning LLMs depend on chain-of-thought (CoT) supervision, which is expensive to collect for robotic tasks, and reinforcement learning (RL) faces challenges in reward engineering. We propose Self-CriTeach, an LLM self-teaching and self-critiquing framework in which an LLM autonomously generates symbolic planning domains that serve a dual role: (1) In the self-teaching stage, generated domains are used to produce large-scale robotic planning problem--plan pairs, which are automatically converted into extended CoT trajectories for supervised fine-tuning. (2) In the self-critiquing stage, the same domains are reused as structured reward functions, providing dense feedback for reinforcement learning without manual reward engineering. This unified training pipeline yields a planning-enhanced LLM with higher planning success rates, stronger cross-task generalization, reduced inference cost, and improved resistance to imperfect logical states.

Referee Report
Summary. The paper proposes Self-CriTeach, a unified LLM self-teaching and self-critiquing framework for robotic planning. An LLM autonomously generates symbolic planning domains that are used (1) to synthesize large-scale problem-plan pairs converted into extended CoT trajectories for supervised fine-tuning and (2) as structured reward functions (goal predicates, action preconditions/effects) for reinforcement learning. The authors claim the resulting planning-enhanced LLM achieves higher success rates, stronger cross-task generalization, reduced inference cost, and improved robustness to imperfect logical states.
Significance. If the generated domains prove sufficiently accurate and the empirical gains hold, the approach would offer a scalable alternative to manual domain engineering and reward design, addressing data scarcity for CoT supervision and reward engineering in LLM-based robotic planners.
major comments (2)
- [Abstract and §3] Abstract and §3 (framework description): the central claim that LLM-generated domains are of sufficient quality to serve as reliable sources for both extended CoT trajectories and dense RL reward signals rests on an unverified assumption. No error analysis, predicate accuracy metrics, or expert validation of the generated domains (e.g., correctness of action schemas or state transitions) is reported, yet any systematic errors would directly corrupt both the SFT data and the RL rewards.
- [§4] §4 (experiments): the manuscript asserts higher planning success rates, stronger cross-task generalization, and robustness to imperfect states, but provides no quantitative results, baselines, ablations against hand-crafted domains, or fidelity checks on the generated domains. Without these, the causal improvements cannot be assessed.
minor comments (1)
- [Abstract] The GitHub link is given but the paper lacks an explicit reproducibility statement or details on how the generated domains and trajectories can be inspected.

Referee: [Abstract and §3] Abstract and §3 (framework description): the central claim that LLM-generated domains are of sufficient quality to serve as reliable sources for both extended CoT trajectories and dense RL reward signals rests on an unverified assumption. No error analysis, predicate accuracy metrics, or expert validation of the generated domains (e.g., correctness of action schemas or state transitions) is reported, yet any systematic errors would directly corrupt both the SFT data and the RL rewards.
Authors: We agree that explicit validation metrics would strengthen the central claim. The self-critiquing stage is intended to detect and correct domain errors through iterative LLM feedback, but we acknowledge that the current version lacks quantitative error analysis or expert validation of predicate accuracy and state transitions. In the revised manuscript we will add a dedicated analysis subsection reporting domain fidelity metrics (e.g., percentage of valid action schemas and state transitions) and the success rate of the self-critiquing loop in producing usable domains. revision: yes

Referee: [§4] §4 (experiments): the manuscript asserts higher planning success rates, stronger cross-task generalization, and robustness to imperfect states, but provides no quantitative results, baselines, ablations against hand-crafted domains, or fidelity checks on the generated domains. Without these, the causal improvements cannot be assessed.
Authors: We accept that the current experimental section would benefit from more comprehensive quantitative support. While §4 presents initial success-rate and generalization results, we did not include full ablations against hand-crafted domains or explicit fidelity checks. In the revision we will expand the experiments with (i) tabulated success rates and inference-cost comparisons, (ii) ablations contrasting LLM-generated versus hand-crafted domains, and (iii) fidelity metrics linking domain quality to downstream planning performance, thereby clarifying the causal contribution of the proposed pipeline. revision: yes
Circularity Check
No significant circularity; framework evaluated on external benchmarks
full rationale
The paper proposes a pipeline in which LLM-generated symbolic domains supply CoT data for SFT and structured rewards for RL. Claimed outcomes (higher planning success rates, cross-task generalization, reduced inference cost, robustness to imperfect states) are measured against external task performance rather than quantities defined by the method's own fitted parameters or self-referential equations. No self-definitional loops, fitted inputs renamed as predictions, or load-bearing self-citations appear in the provided text. The derivation remains self-contained against independent success metrics.
