SKILL0 introduces the first RL framework that internalizes agent skills into model parameters through In-Context Reinforcement Learning and Dynamic Curriculum. By providing skills during training but removing them at inference, it achieves +9.7% improvement on ALFWorld and +6.
核心问题
Can agent skills be internalized into model parameters rather than relying on inference-time skill augmentation, thereby addressing limitations of retrieval noise, token overhead, and lack of competence internalization?
核心方法
{'approach': 'SKILL0 uses In-Context Reinforcement Learning (ICRL) that provides skills during training rollouts but removes them entirely at inference time, combined with a Dynamic Curriculum that adaptively withdraws skills based on on-policy helpfulness evaluation. The framework employs a composite reward that jointly optimizes task success and compression efficiency through PPO-style training on Qwen2.5-VL models.', 'key_components': [], 'section_ids': []}

The paper proposes SKILL0 and demonstrates it works experimentally, but two aspects are problematic: (1) The 'first' claim cannot be verified from the paper alone - it requires exhaustive knowledge of all prior work. (2) 'Zero-shot behavior' is misch
The ICRL mechanism is clearly specified: skills are provided during training rollouts and removed at inference. This is demonstrated through the experimental setup where models are evaluated both with and without skills (Figure 5, Table 1). The trans
Dynamic Curriculum is well-specified with Algorithm 1 and Section 3.3 providing implementation details. The helpfulness metric Δk is computed by comparing performance with/without each skill. Ablation studies in Table 2 show the three-step Filter/Ran
This restates the ICRL contribution. The paper clearly specifies that skills are provided during training (via skill budget M(s) and selection process) and removed at inference (S^(NS) = ∅). The experimental results in Figure 5 and Table 1 show model
The helpfulness evaluation mechanism is clearly specified in Section 3.3 and Algorithm 1. Each skill file Sk is evaluated on its matched validation sub-task Tk under two conditions (with/without skill). The budget annealing is demonstrated with speci
Specific numerical improvements are reported: +9.7% for ALFWorld and +6.6% for Search-QA over AgentOCR. These appear to be derived from Table 1 results (though the table itself is referenced but not fully shown in the excerpts). The claim of 'competi
Specific token counts are provided: 0.38k tokens/step on ALFWorld and 0.18k on Search-QA for 3B models, both under 0.5k. These are compared against SkillRL's 2.21k and 0.87k respectively. The paper demonstrates this efficiency is achieved while maint
The directory structure is stated as a design choice, but no justification or ablation is provided for why this particular organization was chosen over alternatives. The paper mentions it but doesn't demonstrate its necessity or compare against other
The context rendering mechanism is described in p_11, mapping textual context to RGB image via vision encoder. However, the paper credits this to Feng et al. (2026), so this is more of an adaptation than a novel contribution. The mechanism is specifi
The policy self-generating compression ratio ct is stated, but no ablation study compares this against fixed compression ratios. The paper doesn't demonstrate why this design choice is superior to alternatives or provide analysis of how the self-gene
The composite reward formulation is clearly specified in Equation 4 (referenced as Eq. 4 in p_24). It combines task success indicator Isucc(τ) with compression efficiency via logarithmic formulation. The trade-off parameter λ is mentioned. This is a
The linear decay formulation is specified in p_19, with concrete examples provided: [6,3,0] for ALFWorld and [5,3,0] for Search-QA. The paper explains this bounds the step-wise reduction and limits distribution shift. Ablation in Figure 7 compares ag
The two-phase curriculum is clearly described: (a) offline relevance-driven skill grouping in p_22, and (b) online helpfulness-driven dynamic curriculum in p_23. Both phases are specified with implementation details and the overall framework is valid
The relevance definition and partitioning process are described, but the paper doesn't provide examples of how this matching is done in practice or validate that this particular grouping strategy is optimal. The claim is stated but not rigorously dem
The helpfulness metric Δk is clearly defined and its computation (evaluating Tk with/without Sk) is specified. The validation interval d is explored in Table 3, with d=10 selected as optimal. This is a well-specified and validated design choice.
Specific implementation details are provided: Qwen2.5-VL series, max 180 steps, 4 H800 GPUs, batch sampling 16 tasks with 8 rollouts, max prompt length 3,072 tokens for ALFWorld. These are concrete, verifiable specifications.
Specific hyperparameter values are provided: validation subset size 1,000, NS=3 curriculum stages, SkillBank initialized from SkillRL. These are concrete implementation details.
Specific token consumption numbers are provided: SKILL0 uses 0.38k (ALFWorld) and 0.18k (Search-QA), compared to SkillRL's 2.21k and 0.87k. The 5× reduction claim is mathematically verifiable from these numbers (2.21/0.38 ≈ 5.8×, 0.87/0.18 ≈ 4.8×).
The claim references Figure 3 and 4 showing reward curves. While the figures themselves aren't fully reproduced in the excerpts, the paper explicitly states SKILL0 maintains 'consistently higher reward curves on both the 3B and 7B backbones compared
This finding is supported by Figure 5(a) which shows validation accuracy with and without skill prompts over training. The paper describes the pattern: faster early improvement with skills, gradual catch-up without skills. This demonstrates skill int
