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 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 67 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 67 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
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 | $0.00014 | $0.02562 |
| Opus 5.5 | $0.00006 | $0.01025 |
| Sonnet 5.5 | $0.00003 | $0.00512 |
| Haiku 4.5 | $0.00001 | $0.00256 |
Grade C, and why
parallel-cli 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 1mo 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.

How it starts
The opening of the file, as written. The whole thing — 392 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Parallel CLI
Use parallel-cli when the user explicitly wants Parallel, or when a terminal-native workflow would benefit from Parallel's vendor-specific stack for web search, extraction, deep research, enrichment, entity discovery, or monitoring.
This is an optional third-party workflow, not a Hermes core capability.
Important expectations:
- Parallel is a paid service with a free tier, not a fully free local tool.
- It overlaps with Hermes native
web_search/web_extract, so do not prefer it by default for ordinary lookups. - Prefer this skill when the user mentions Parallel specifically or needs capabilities like Parallel's enrichment, FindAll, or monitor workflows.
parallel-cli is designed for agents:
- JSON output via
--json - Non-interactive command execution
- Async long-running jobs with
--no-wait,status, andpoll - Context chaining with
--previous-interaction-id - Search, extract, research, enrichment, entity discovery, and monitoring in one CLI
When to use it
Prefer this skill when:
- The user explicitly mentions Parallel or
parallel-cli - The task needs richer workflows than a simple one-shot search/extract pass
- You need async deep research jobs that can be launched and polled later
- You need structured enrichment, FindAll entity discovery, or monitoring
Prefer Hermes native web_search / web_extract for quick one-off lookups when Parallel is not specifically requested.
Installation
Try the least invasive install path available for the environment.
Homebrew
brew install parallel-web/tap/parallel-cli
npm
npm install -g parallel-web-cli
Python package
pip install "parallel-web-tools[cli]"
Standalone installer
curl -fsSL https://parallel.ai/install.sh | bash
If you want an isolated Python install, pipx can also work:
pipx install "parallel-web-tools[cli]"
pipx ensurepath
Authentication
Interactive login:
parallel-cli login
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.

parallel-cli is a skill published in the GitHub repository NousResearch/hermes-agent (255,903 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 2,562 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 2026-09-03.
