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.
npx agentmods add agents/boldblackai/harness/hermesgit clone --depth 1 https://github.com/boldblackai/harnessWhat 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 | $0.00000 | $0.00343 |
| Opus 5 | $0.00000 | $0.00171 |
| Sonnet 5 | $0.00000 | $0.00069 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
hermes 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 2d 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.
What it actually says
hermes
hermes by NousResearch is a full-featured agent supporting many providers. It is the recommended choice for long-running "claw" deployments.
Local mode
npx @boldblackai/harness -a hermes -p "add tests"
LM Studio context length should be at least 64k tokens.
Cloud mode
Pass --env-file to enter cloud mode — the agent auto-detects the provider from env vars.
echo "ANTHROPIC_API_KEY=sk-ant-***" > .env
npx @boldblackai/harness -a hermes -e .env -p "add tests"
npx @boldblackai/harness -a hermes -e .env -m openrouter/auto -p "add tests"
Common keys: ANTHROPIC_API_KEY, OPENROUTER_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY. See full list.
The -m flag takes provider/model format.
Deploying as a claw
Hermes can be deployed as a long-running persistent agent ("claw") reachable over a messaging gateway like Telegram. See the deployment guides:
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.

hermes is an agent published in the GitHub repository boldblackai/harness (10 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 343 tokens. 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 2026-08-31.

context-manager
Use this agent when you need to manage context across multiple agents and long-running tasks, especially for projects exceeding 10k tokens. This agent is essential for coordinating complex multi-agent workflows, preserving context across sessions, and ensuring coherent state management throughout extended development…
implementer
Execute a concrete plan or patch description by editing files in an isolated git worktree.
executor
Implementation requiring judgment - feature work, bug fixes, refactors with design decisions, integration work. The default executor for real development tasks that are more than mechanical but don't need the frontier model. Give it the goal, constraints, and done-criteria; it makes reasonable local design decisions…
