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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00018 | $0.02402 |
| Opus 5 | $0.00009 | $0.01201 |
| Sonnet 5 | $0.00004 | $0.00480 |
| Haiku 4.5 | $0.00002 | $0.00240 |
Grade A, and why
sketch 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 8d 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.

How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sketch
Use this skill when the user wants to see a design direction before committing to one — exploring a UI/UX idea as disposable HTML mockups. The point is to generate 2-3 interactive variants so the user can compare visual directions side-by-side, not to produce shippable code.
Load this when the user says things like "sketch this screen", "show me what X could look like", "compare layout A vs B", "give me 2-3 takes on this UI", "let me see some variants", "mockup this before I build".
When NOT to use this
- User wants a production component — use
claude-designor build it properly - User wants a polished one-off HTML artifact (landing page, deck) —
claude-design - User wants a diagram —
excalidraw,architecture-diagram - The design is already locked — just build it
If the user has the full GSD system installed
If gsd-sketch shows up as a sibling skill (installed via npx get-shit-done-cc --hermes), you can use gsd-sketch for the fuller workflow: persistent .planning/sketches/ with MANIFEST, frontier mode analysis, consistency audits across past sketches, and integration with the rest of GSD. This skill is the lightweight standalone version — one-off sketching without the state machinery.
Note: The upstream GSD project (gsd-build/get-shit-done) is archived / no longer maintained on GitHub. The npm package (
get-shit-done-cc) still installs, but treat it as an archived community project — this standalonesketchskill is the maintained path and needs nothing extra.
Core method
intake → variants → head-to-head → pick winner (or iterate)
1. Intake (skip if the user already gave you enough)
Before generating variants, get three things — one question at a time, not all at once:
- Feel. "What should this feel like? Adjectives, emotions, a vibe." — "calm, editorial, like Linear" tells you more than "minimal".
- References. "What apps, sites, or products capture the feel you're imagining?" — actual references beat abstract descriptions.
- Core action. "What's the single most important thing a user does on this screen?" — the variants should all serve this well; if they don't, they're just decoration.
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.

sketch is a skill published in the GitHub repository NousResearch/hermes-agent (243,146 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 2,402 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 2026-08-30.
Other skills, from other repositories
ui-animation
Builds, reviews, and measures UI motion, including springs, gestures, scroll effects, and curve fitting from recordings. Use when asked to "add animation", "match this easing", "reverse engineer this motion", or find animation opportunities. For action semantics use product-design; for visual layout use ui-design.
ui-design
Designs and builds React/Next/Tailwind UI and audits visual and interaction defects. Use when asked to "build a landing page", "extract our design system", "add dark mode", "make this responsive", "remove UI slop", or "audit this component". For product decisions use product-design; for browser measurements use…
typography-audit
Audits font loading, type scales, measure, spacing, OpenType, and rendered punctuation with 78 scoped rules. Use when asked to "audit typography", "fix the fonts", or "review my type system". For a new visual direction use ui-design Direction; for general UI defects use ui-design Audit.
frontend-design
Guidance for distinctive, intentional visual design when building or reshaping UI, HTML/React artifacts, dashboards, charts, and visual reports. Use before implementation to choose a content-specific structure, typography, and visual system that does not read as a templated default.
motion-system
Define the app's motion language before animating anything -- a small set of durations, easings, and named moves that every animation draws from, so the app feels designed instead of decorated. Use before writing the first animation in a project, or when existing motion feels scattered.
polish-pass
The de-AI pass -- audit a vibe-coded app for template smell in design and copy, then fix it with editorial layout, purposeful motion, and human-sounding words. Use after any build session, before anyone else sees it.
