Which Hermes Agent Skills Should You Install?

TL;DR

Install compact Hermes skills that reduce token use, improve task clarity, clean web content, and add capabilities your workflows actually need. The creator recommends starting with SkillClaw for automatic skill maintenance, then selecting tools such as Defuddle, Humanizer, youtube-full, Composio, Mission Control, and OpenMontage according to your research, writing, integration, development, or multi-agent needs.

Did you know that a good Hermes skill stays under 15 kilobytes? Otherwise, it can bloat your agent memory and burn extra tokens. I've used hundreds of skills at this point, and majority of them are completely trash. So, here are my top 14 Hermy skills I'd actually install right now. Oh, and if we haven't met yet, I'm Doobie. I build apps every day ... Read More

Key Insights

• A Hermes skill is a markdown file that gives an agent step-by-step instructions for completing a particular task. Once installed from a GitHub repository, it can be activated by a relevant prompt or invoked directly by asking Hermes to use that named skill.
• Compact skills are preferable because the creator says a good Hermes skill stays under 15 kilobytes. Larger skill files can occupy more agent memory and consume extra tokens, so usefulness should be weighed against the amount of persistent context each installation introduces.
• SkillClaw is an automated maintenance tool that runs an evolution loop after sessions. It reviews used skills, removes overlapping duplicates, rewrites weak instructions, and updates the library, allowing the agent's skill collection to improve through ordinary use without continual manual maintenance.
• Matt Pocock's skills pack contains 15 skills, with Grill Me, Caveat, and Teach Me highlighted. Grill Me asks five targeted questions before coding, Caveat can reduce token usage by up to 75%, and Teach Me presents practical instructional takeaways in HTML.
• Defuddle is a web-processing skill that removes navigation, footers, cookie notices, sidebars, and advertisements before an agent reads a page. It converts the remaining material into reader-mode markdown, which the creator says lets an agent process web content three to four times more efficiently.
• Humanizer is a built-in Hermes skill designed to reduce recognizable signs of AI-generated writing. It draws on a Wikipedia page about signs of AI writing, updates when that page changes, and rewrites agent output into a more natural voice before publication.
• youtube-full replaces the default Hermes YouTube skill for agents running on VPS or cloud infrastructure, where the creator says YouTube blocks cloud IPs. It supports transcript extraction, channel browsing, playlist parsing, and video search without requiring a Google API key.
• Mission Control provides centralized oversight for multiple Hermes agents assigned to research, coding, and client communication. Its dashboard supports task dispatch, agent health monitoring, real-time cost tracking, and live status, eliminating the need to inspect each agent through a separate terminal.

Questions & Answers

Q: What is a Hermes Agent skill and how does it work?

A Hermes Agent skill is a markdown file containing step-by-step instructions that teach the agent how to perform a task. The creator says installation can be handled by copying a skill's GitHub repository and asking Hermes to install it. After installation, the skill remains available in the agent's memory and can activate from a relevant prompt or through an explicit request to use it.

Q: Why should a Hermes skill stay under 15 kilobytes?

The creator recommends keeping a good Hermes skill below 15 kilobytes because oversized instructions can bloat the agent's memory and consume additional tokens. Since installed skills remain available to the agent, unnecessary detail can make the setup less efficient. The practical lesson is to favor concise, task-specific instructions and avoid installing large or overlapping skills that add context without delivering enough value.

Q: How does SkillClaw improve a Hermes Agent setup?

SkillClaw prompts the agent to run an evolution loop after each session. During that process, it reviews the skills that were used, removes duplicates that overlap, rewrites weaker skills, and updates the skill library automatically. The creator recommends installing it before the other options because this maintenance happens passively and can make the overall setup progressively sharper through normal daily use.

Q: Which Matt Pocock skills are highlighted for Hermes Agent?

The creator highlights three skills from Matt Pocock's pack of 15. Grill Me asks five targeted questions before any code is written, reducing misunderstandings about the requested product. Caveat removes token bloat from long sessions and is claimed to cut token use by up to 75%. Teach Me gives the agent a teaching framework and organizes practical takeaways into readable HTML.

Q: How does Defuddle reduce token use during web research?

Defuddle removes page elements that usually do not contribute to research, including navigation, footers, cookie banners, sidebar advertisements, and similar clutter. It then converts the useful page content into clean, reader-mode markdown before the agent processes it. The creator says this approach makes web reading three to four times more efficient for research, competitive analysis, market analysis, and documentation lookups.

Q: What does the Humanizer skill do for AI writing?

Humanizer rewrites an agent's output into a more natural human voice before the material is published. The skill is based on a Wikipedia page describing telltale signs of AI writing and is said to update whenever that page changes. It is presented as a final editing step for AI-assisted emails, proposals, social posts, and other content that might otherwise sound recognizably machine-generated.

Q: How does youtube-full help Hermes agents in cloud environments?

youtube-full replaces the default YouTube capability that, according to the creator, breaks on VPS and cloud environments because YouTube blocks cloud IPs. The replacement provides transcript extraction, channel browsing, playlist parsing, and video search without a Google API key. The creator uses YouTube transcripts as specialized source material, including examples that help agents study and improve YouTube script writing.

Q: When should you use Mission Control or OpenMontage?

Mission Control is intended for people operating several Hermes agents and needing one place to dispatch tasks, monitor agent health, view live status, and track costs in real time. OpenMontage serves a different purpose: agentic video production. It analyzes a reference video's transcript, pacing, scenes, key frames, and tone, then proposes two to three concepts, a tool path, a cost estimate, and a preview before generation.

Summary & Key Takeaways

• Hermes skills are markdown files that teach an agent to complete tasks step by step. They can be installed by giving the agent a GitHub repository and can activate automatically or through direct prompting. The creator advises keeping useful skills under 15 kilobytes because larger files may consume additional memory and tokens.

• The recommended efficiency tools address recurring agent problems. SkillClaw reviews and improves the skill library after sessions, Matt Pocock's pack clarifies requirements and reduces session bloat, Defuddle cleans web pages before processing, and Humanizer rewrites generated text in a more natural voice before emails, proposals, or social posts are published.

• The capability and infrastructure recommendations expand what Hermes can access and manage. youtube-full handles transcripts and channel functions in cloud environments, Composio connects business applications, Addy Osmani's pack supports development workflows, and Resemble AI Detect examines submitted media. Mission Control coordinates multiple agents, while OpenMontage provides an agentic video-production system.
