I Rebuilt Hermes in Claude Code (It’s Ridiculously Good)
The creator rebuilds key features of the Hermes agentic AI system inside their own Claude Code setup rather than installing it off-the-shelf, arguing that understanding the architecture provides more long-term leverage. They identify three hidden costs of pre-built systems: inherited assumptions, inability to fix unknown code, and poor scalability. Their custom build addresses Hermes's limitations in multi-client identity management, semantic memory recall, and skill system maintainability.
Summary
The video opens by noting Hermes reached 40,000 GitHub stars in 46 days — faster than OpenClaw — making it the fastest-adopted agentic system on GitHub. Rather than installing Hermes directly, the creator read through its GitHub issues first and decided to rebuild the desired features within their own Claude Code setup, prioritizing understanding over speed of adoption.
The creator outlines three hidden costs of off-the-shelf agentic systems. First, inherited assumptions: Hermes's self-learning loop has no external guardrails, meaning the same model that writes a skill also validates it, creating a self-validation problem with no version control or audit log. Second, inability to fix unknown code: OpenClaw, a comparable product, had over 200 vulnerabilities filed since February, including 386 malicious packages from a single threat actor on its skills marketplace — and users can't debug what they don't understand. Third, scalability problems: a non-technical CEO spent over 100 hours and $1,000 testing OpenClaw over two months before concluding its bugs and security gaps made it unusable for business.
On the identity layer, Hermes uses memory.md and user.md files injected at the start of every conversation, but assumes a single user working on a single set of projects. The creator's solution adds shared brand context per client — voice, ICP, visual identity — while allowing skills and procedures to be shared across clients from a single installation, avoiding the maintenance overhead of multiple separate Hermes installs.
On memory, Hermes autosaves and summarizes conversations, injects context capped at roughly 1,300 tokens, but relies on keyword-based long-term recall — a significant limitation when users can't remember exact words used in past sessions. The creator's system retains the injected recent-memory pattern but replaces keyword search with semantic search (via a system like MemSearch) for deeper recall, making long-term memory practically useful.
On the self-learning loop, the creator argues that Hermes's automatic skill-writing creates compounding maintenance problems: over time, similar tasks generate near-duplicate skills with overlapping descriptions, making it unclear which skill to use and requiring updates in multiple places when context changes. Their alternative is a modular 'skill systems' architecture where each skill does one job, lives in one place, and is referenced by skill systems that chain components together. When brand voice or client positioning changes, only one file needs updating, and all dependent skill systems reflect the change automatically.
The video concludes that Hermes is faster to start but custom builds are faster to scale. The creator positions their 'Agentic OS' — available in their Agentic Academy — as a middle ground: installable in one line but with full architectural transparency, allowing users to understand and modify every assumption.
Key Insights
- The creator argues that Hermes's self-learning loop has a self-validation problem: the same model that writes a skill is also the sole judge of its correctness, meaning it can silently overwrite user-improved skills with worse versions and has no version control or audit log.
- The creator points out that Hermes's single-install architecture assumes one user working on one project, meaning agencies or multi-brand owners must spin up entirely separate Hermes installations per client — each with its own isolated memory and skills — creating a compounding maintenance problem where shared procedures must be duplicated across installs.
- The creator identifies that Hermes's long-term memory recall is keyword-based rather than semantic, making it practically useless for retrieving conversations from months ago when users cannot remember the exact words they originally used with Claude.
- The creator argues that Hermes's automatic skill-generation loop leads to skill sprawl over time — potentially 15 near-duplicate skills for similar tasks like LinkedIn posts — with overlapping descriptions that make it unclear which skill to invoke, and no single update point when brand voice or positioning changes.
- A non-technical CEO spent over 100 hours and $1,000 testing OpenClaw over two months and ultimately concluded its bugs and security gaps disqualified it from any usable business application, but has since replicated roughly 30% of OpenClaw's features in Claude within a couple of months.

[0:00] Hermes went from zero to 40,000 GitHub stars in 46 days. And to compare, OpenClaw did it in 61. So for Aentic systems, this is the fastest adoption ever seen on GitHub. And when you look at what they do, the memory systems, the identity layers, and the self-learning loops, you can understand why. But before I installed it, I did something most people don't do. I went and read through the issues. And pretty quickly, I realized something that off-the-shelf systems are fast to begin with. They're fast to start. But you inherit somebody [0:30] else's architecture, their assumptions, and therefore their problems, too. You can't fix what you don't understand underneath. So, instead of replacing claw code,…

Agentic AI Systems, Clearly Explained
This video explains agentic AI systems across four levels of complexity: chatbots, AI workflows, agentic workflows, and agentic AI systems. Using content repurposing as a consistent example, the speaker demystifies intimidating terms like harnesses, MCPs, and memory systems, arguing that these systems are fundamentally just files and folders accessible to non-developers.
Stop Downloading Claude Code Skills. Do This Instead.
The video argues that downloaded Claude Code skills are too isolated or bloated to drive real business outcomes. The speaker introduces 'skill systems' — orchestrated chains of small, focused skills that feed into each other end-to-end. A practical example shows a five-skill automation that converts a YouTube video into five ready-to-post short-form clips.
Master 80% of Claude Code, Just Learn These 15 Things
This tutorial covers 15 foundational concepts for using Claude Code effectively, emphasizing that context management is the single most critical skill. The presenter draws from real user behavior across thousands of users to show how plan mode, context tools, slash commands, skills, hooks, MCPs, and memory systems combine to form a powerful agentic workflow.
Master Claude Design in One Video (Complete Build)
The video demonstrates a live build using Claude Design to create real business assets for the Aentic Academy, including a landing page, mobile wireframe, and slide deck. The host emphasizes that building a proper design system upfront is the single most important factor in avoiding generic AI aesthetics. The video compares multiple methods: using ChatGPT's image model, the Skill UI CLI tool, and Claude Design's native interface.
Claude just got another superpower (but they kept it quiet!)
A creator discovers buried features in a recent Claude desktop app update, including file system visibility, split-view sessions, and markdown rendering. These changes make the desktop app a viable replacement for terminal-based Claude Code workflows. The creator argues this enables structured, context-aware agentic project management without needing VS Code or a terminal.
