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.

- NVIDIA SkillSpector warn
SkillSpector: 4 findings, up to high
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 →
- high Supply Chain · line 69 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- medium Rogue Agent · line 18 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 | $0.00019 | $0.04009 |
| Opus 5 | $0.00010 | $0.02005 |
| Sonnet 5 | $0.00004 | $0.00802 |
| Haiku 4.5 | $0.00002 | $0.00401 |
Grade A, and why
tldraw-offline scanned grade A with 1 finding 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 10d 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.

The opening of the file, as written. The whole thing — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tldraw offline Skill
Work with the tldraw offline desktop app (offline.tldraw.com): read the open
canvas, make edits, and write document scripts — JavaScript embedded in a
.tldraw file that runs on load and gives the file durable behavior. The app
runs a local HTTP API (default localhost:7236) that a coding agent drives
with plain curl from its terminal — this is exactly how the app's own homepage
demo (Codex editing a canvas live) works. The agent does NOT use computer-use /
GUI clicking, and does NOT hand-edit the .tldraw file directly. Keep tldraw
offline open while you work.
When to Use
- The user has tldraw offline open and asks you to build or modify a canvas (diagrams, wireframes, layouts).
- You want to add durable behavior to a drawing (reactive shapes, interactive buttons, animation, connection logic) via an embedded document script.
Do NOT hand-place shapes to imitate a drawing — write the code that generates them. Agents are far better at scripting the canvas than at drawing on it.
Prerequisites
- tldraw offline installed and running, with a document open. Releases:
https://github.com/tldraw/tldraw-offline/releases/latest (macOS DMG, Windows
x64/Arm64, Linux
x86_64/arm64AppImage or amd64/arm64.deb). - Agent skills installed in the app:
Develop → Install Agent Skills. The app writes its own tldraw skill into~/.codex/skills/,~/.claude/skills/,~/.cursor/skills/, and~/.gemini/skills/— teaching that agent thecurlrecipes below. (This Hermes skill mirrors that guidance for Hermes.) - The local control API. On launch the app writes
server.jsonto its config dir (Linux~/.config/tldraw/, macOS~/Library/Application Support/tldraw/, Windows%APPDATA%\tldraw\) withport(default7236), a bearertoken,pid, andstartedAt. Every request exceptGET /needsAuthorization: Bearer <token>. A clean quit removesserver.json; if it's present but the port doesn't answer, the app quit uncleanly — treat as not running. - Re-read port + token on EVERY shell call. Each terminal call is a fresh
shell, so an
exported token does not persist — "export once and reuse" sends an empty token and 401s. Read both inline at the top of each call:PORT=$(jq -r .port <server.json>); TOKEN=$(jq -r .token <server.json>). - No account or network needed for local editing.
What ships with it
3 files 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.

tldraw-offline is a skill published in the GitHub repository NousResearch/hermes-agent (243,598 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 4,009 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
