# Peilivanidis argues agents should be equipped with modular software capabilities [Canonical reading](https://escapemeridian.com/readings/peilivanidis-argues-agents-should-be-equipped-with-modular-0be1d373) In an arXiv paper, Vladimiros Peilivanidis argues that agents should use Skillware—modular, versioned software capability bundles—instead of relying on prompts to generate code, guess API payloads and remember operational constraints. He presents each bundle as combining a typed JSON input contract, deterministic Python code, task directives, bundled datasets and automated unit tests. Adapters, he says, translate the capabilities into tool declarations for different models, including local systems that run without network latency. The paper reports an evaluation of 23 frontier and open-weight models across 368 benchmark conditions. Its abstract says small local models equipped with Skillware outperformed unequipped frontier models on complex multi-step workflows, while reducing token use and inference costs and eliminating parameter errors in those conditions. Peilivanidis uses these results to argue that agent reliability should come from verified, deterministic software rather than larger models or longer prompts. The proposal’s practical significance, as presented, is to move operational rules and execution into testable software bundles rather than leave them in model-generated instructions. The abstract also describes a possible extension from digital systems to IoT, drones and embodied robotics. It does not establish how well the reported results generalize beyond the

The framing keeps the performance and reliability claims as the author's assertions, not established fact. > Authors:Vladimiros Peilivanidis (ARPA Hellenic Logical Systems) summary — uncertain: The summary's final paragraph breaks off mid-sentence: "It does not establish how well the reported results generalize beyond the". That leaves the limitation incomplete. Smallest repair: finish the sentence, for example "...beyond the evaluated conditions." Central terms such as API payloads, typed JSON input contract, token use, open-weight and frontier models lack plain-language glosses or term-library tooltips, which may block a non-specialist reader. The author's video-game skill-hotkey analogy would help here and could be restored. Title and question are faithful and non-leading. > Much like skill hotkeys in video games that execute deterministically under fixed world rules date — pass: originalPublished 2026-11-05 matches the arXiv v1 submission date.

Results are scoped to the evaluated conditions and labeled as abstract claims. The extension to IoT, drones and robotics is presented as a trajectory, not a demonstrated result. The limitations correctly note that only the abstract was available.
