Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00015 | $0.01536 |
| Opus 5 | $0.00008 | $0.00768 |
| Sonnet 5 | $0.00003 | $0.00307 |
| Haiku 4.5 | $0.00002 | $0.00154 |
Grade A, and why
architecture-diagram scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture Diagram Skill
Generate professional, dark-themed technical architecture diagrams as standalone HTML files with inline SVG graphics. No external tools, no API keys, no rendering libraries — just write the HTML file and open it in a browser.
Scope
Best suited for:
- Software system architecture (frontend / backend / database layers)
- Cloud infrastructure (VPC, regions, subnets, managed services)
- Microservice / service-mesh topology
- Database + API map, deployment diagrams
- Anything with a tech-infra subject that fits a dark, grid-backed aesthetic
Look elsewhere first for:
- Physics, chemistry, math, biology, or other scientific subjects
- Physical objects (vehicles, hardware, anatomy, cross-sections)
- Floor plans, narrative journeys, educational / textbook-style visuals
- Hand-drawn whiteboard sketches (consider
excalidraw) - Animated explainers (consider an animation skill)
If a more specialized skill is available for the subject, prefer that. If none fits, this skill can also serve as a general SVG diagram fallback — the output will just carry the dark tech aesthetic described below.
Based on Cocoon AI's architecture-diagram-generator (MIT).
Workflow
- User describes their system architecture (components, connections, technologies)
- Generate the HTML file following the design system below
- Save with
write_fileto a.htmlfile (e.g.~/architecture-diagram.html) - User opens in any browser — works offline, no dependencies
Output Location
Save diagrams to a user-specified path, or default to the current working directory:
./[project-name]-architecture.html
Preview
After saving, suggest the user open it:
# macOS
open ./my-architecture.html
# Linux
xdg-open ./my-architecture.html

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architecture-diagram is a skill published in the GitHub repository NousResearch/hermes-agent (244,059 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 1,536 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

design
Create a design canvas - a multi-artboard visual design published as an Artifact that runs Claude Design's canvas editor (an early preview of Claude Design inside Claude Code). You DRAFT the design as .dc.html artboards laid out on one pan/zoom canvas; where saving is enabled for the user's account they refine every…
create-design-system
Skill to use if user asks you to create a design system or UI kit.
hi-fi-design
The design process for high-fidelity, polished work — the system prompt tells Claude to invoke it before starting any design.
options
Present multiple design options as a vertical stack of anchored turns.
wireframe
Explore many ideas with wireframes and storyboards.
design-sync
Push a React design system to claude.ai/design. This runs a converter that bundles the real component code (from Storybook or a bare package) and uploads it. Use when the user runs /design-sync or says "sync my design system to Claude Design".
