Self-Guided Plan Extraction for Instruction-Following Tasks with Goal-Conditional Reinforcement Learning
Pith reviewed 2026-05-10 00:00 UTC · model grok-4.3
The pith
A co-training loop lets a language model and RL agent jointly improve plans for following instructions without manual labels.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
SuperIgor uses iterative co-training in which an RL agent learns to follow plans generated by a language model, and the language model then adapts those plans based on the agent's feedback and preferences. This mutual improvement process allows the system to produce effective high-level plans without predefined subtasks or manual annotation, leading to agents that adhere more strictly to given instructions and generalize better to unseen ones in stochastic environments.
What carries the argument
The iterative co-training loop in which the goal-conditional RL agent executes language-model plans and supplies feedback that lets the model revise the plans.
If this is right
- Agents trained under this loop adhere to instructions more strictly than those trained with baseline methods.
- The resulting agents generalize effectively to previously unseen instructions.
- High-level plans can be generated and refined without requiring manual dataset annotation or predefined subtasks.
- The framework operates successfully in environments that contain rich dynamics and stochasticity.
Where Pith is reading between the lines
- The same feedback-driven refinement might be applied to other planning domains where execution outcomes can be observed directly.
- Reducing reliance on labeled data could make instruction-following systems easier to deploy in new environments.
- Longer training loops might reveal whether the improvements continue or plateau after several rounds of co-training.
Load-bearing premise
The iterative co-training loop between the RL agent and language model produces reliable improvements in plan quality without external supervision or manual annotation.
What would settle it
Running SuperIgor agents and baseline agents side by side in the same stochastic environments and finding no measurable gain in instruction adherence or generalization to new instructions would show the claimed advantage does not hold.

read the original abstract
We introduce SuperIgor, a framework for instruction-following tasks. Unlike prior methods that rely on predefined subtasks, SuperIgor enables a language model to generate and refine high-level plans through a self-learning mechanism, reducing the need for manual dataset annotation. Our approach involves iterative co-training: an RL agent is trained to follow the generated plans, while the language model adapts and modifies these plans based on RL feedback and preferences. This creates a feedback loop where both the agent and the planner improve jointly. We validate our framework in environments with rich dynamics and stochasticity. Results show that SuperIgor agents adhere to instructions more strictly than baseline methods, while also demonstrating strong generalization to previously unseen instructions.

A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript introduces SuperIgor, a framework for instruction-following tasks in which a language model generates and iteratively refines high-level plans via a self-guided co-training loop with a goal-conditional RL agent. The RL agent is trained to execute the LM-generated plans while supplying feedback and preferences that allow the LM to adapt the plans, reducing reliance on manual annotation. The authors claim that the resulting agents adhere more strictly to instructions than baselines and generalize better to previously unseen instructions in environments with rich dynamics and stochasticity.
Significance. If the central claims hold, the work would demonstrate a viable path toward annotation-light instruction following by closing the loop between plan generation and execution feedback. The joint improvement of planner and policy is a potentially useful direction for scaling RL-LM hybrids in stochastic settings.
major comments (3)
- [Abstract] Abstract: the claims of stricter instruction adherence and strong generalization to unseen instructions are asserted without any reported metrics, baselines, statistical tests, error bars, or ablation results, so it is impossible to evaluate whether the improvements are load-bearing or merely apparent.
- [Method] Method description of the co-training loop: the manuscript does not specify whether the RL reward contains an auxiliary term for plan fidelity, coverage, or preference alignment beyond raw task completion. Without such a term (or a held-out preference model), the feedback loop risks rewarding short or degenerate plans that the current policy can execute easily rather than genuinely higher-quality plans, undermining the self-improvement claim.
- [Experiments] Experimental validation section: no details are supplied on environment stochasticity levels, number of trials, how 'unseen instructions' were constructed, or how plan quality was measured independently of task success, making it impossible to assess whether reported gains reflect true generalization or training-loop artifacts.

Referee: [Abstract] Abstract: the claims of stricter instruction adherence and strong generalization to unseen instructions are asserted without any reported metrics, baselines, statistical tests, error bars, or ablation results, so it is impossible to evaluate whether the improvements are load-bearing or merely apparent.
Authors: We agree that the abstract, being a high-level summary, does not include quantitative metrics. The full manuscript reports these results in the Experiments section, including baseline comparisons, adherence and generalization metrics, and statistical details. In the revision, we have updated the abstract to concisely reference the key quantitative improvements (e.g., adherence rates and generalization gains) while preserving brevity. All claims remain grounded in the reported experiments. revision: yes

Referee: [Method] Method description of the co-training loop: the manuscript does not specify whether the RL reward contains an auxiliary term for plan fidelity, coverage, or preference alignment beyond raw task completion. Without such a term (or a held-out preference model), the feedback loop risks rewarding short or degenerate plans that the current policy can execute easily rather than genuinely higher-quality plans, undermining the self-improvement claim.
Authors: This is a valid concern. The original description focused on the goal-conditional reward for task completion, with LM adaptation driven by RL-derived preferences. We have revised the Method section to explicitly define the reward function, adding an auxiliary term for plan fidelity and coverage derived from the preference signals. This term penalizes degenerate plans and encourages alignment with high-quality plans. We have also added pseudocode and a diagram of the co-training loop for clarity. revision: yes

Referee: [Experiments] Experimental validation section: no details are supplied on environment stochasticity levels, number of trials, how 'unseen instructions' were constructed, or how plan quality was measured independently of task success, making it impossible to assess whether reported gains reflect true generalization or training-loop artifacts.
Authors: We acknowledge that additional experimental details are needed for reproducibility and assessment. The revised Experiments section now specifies the stochasticity levels (e.g., transition noise parameters), number of trials with error bars across random seeds, the construction of unseen instructions (novel goal-constraint combinations held out from training), and independent plan quality metrics (coverage and fidelity scores computed separately from task success). We have included ablations confirming that gains arise from the co-training loop rather than artifacts. revision: yes
Circularity Check
No significant circularity detected
full rationale
The paper presents SuperIgor as an iterative co-training framework in which an RL agent follows LM-generated plans and supplies feedback for plan refinement. The reported gains in instruction adherence and generalization to unseen instructions are framed as empirical outcomes from this joint process, benchmarked against baselines in stochastic environments. No equations, parameter fits, or self-citations are exhibited in the provided text that reduce the performance claims to the training loop by construction; the loop is offered as a method whose effectiveness is measured externally rather than presupposed. The derivation therefore remains self-contained against the stated validation.
