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: 6 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 37 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.
- high Tool Misuse · line 233 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Never auto-execute commands that modify files, send data, or alter system state.

Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files).

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 | $0.03703 |
| Opus 5.5 | $0.00007 | $0.01481 |
| Sonnet 5.5 | $0.00004 | $0.00741 |
| Haiku 4.5 | $0.00002 | $0.00370 |
Grade C, and why
grok scanned grade C with 2 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 26d 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.

Grok Build CLI — Hermes Orchestration Guide
Delegate coding tasks to Grok Build (xAI's
autonomous coding agent CLI, the grok command) via the Hermes terminal. Grok
can read files, write code, run shell commands, spawn subagents, and manage git
workflows. It runs three ways: an interactive TUI, headless (-p), and as
an ACP agent over JSON-RPC.
This is the third sibling to codex and claude-code. The orchestration
pattern is nearly identical — prefer headless -p for one-shots, use a PTY
for interactive sessions.
When to use
- Building features
- Refactoring
- PR reviews
- Batch issue fixing
- Any task where you'd otherwise reach for Codex / Claude Code but want Grok
Prerequisites
- Install (preferred):
npm install -g @xai-official/grok- The official installer
curl -fsSL https://x.ai/cli/install.sh | bashalso works, but thex.aihost is Cloudflare-walled in some environments. The npm path avoids that dependency entirely.
- The official installer
- Auth — SuperGrok / X Premium+ subscription (primary path):
- Run
grok loginonce → opens a browser for OAuth → token cached in~/.grok/auth.json. This uses your SuperGrok or X Premium+ subscription (no per-token API billing). - Check sign-in state by looking for
~/.grok/auth.json, or run a cheap headless smoke test:grok --no-auto-update -p "Say ok." - In the TUI,
/logoutsigns out and/login(or relaunching) signs back in.
- Run
- No git repo required — unlike Codex, Grok runs fine outside a git directory (good for scratch/throwaway tasks).
- Claude Code / AGENTS.md compatible with zero config — Grok auto-reads
CLAUDE.md,.claude/(skills, agents, MCPs, hooks, rules), and theAGENTS.mdfamily. Existing project context just works.
API-key fallback (not the default for this user): Grok also supports setting the
XAI_API_KEYenvironment variable for pay-as-you-go billing viaapi.x.ai. Only use this ifgrok login/ SuperGrok auth is unavailable. The subscription path (grok login) is the intended setup here.
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.

grok is a skill published in the GitHub repository NousResearch/hermes-agent (254,120 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 3,703 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
