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.

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 | $0.00045 | $0.02258 |
| Opus 5.5 | $0.00018 | $0.00903 |
| Sonnet 5.5 | $0.00009 | $0.00452 |
| Haiku 4.5 | $0.00005 | $0.00226 |
Grade C, and why
hermes-runtime 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.

Hermes Runtime
Use this skill when the user wants Hermes to appear inside NextClaw as a formal session type.
The only preferred product path is:
- runtime entry label:
Hermes - runtime type:
narp-stdio - wire dialect:
acp - runtime entry launcher:
hermes acp - route ownership:
NextClaw -> RuntimeRoute(model/apiBase/apiKey/headers) -> Hermes ACP
Do not present Hermes as:
- a plugin-private integration
- a connector-first integration
- an API-server-first integration
- a second independent provider configuration system
This installed skill must stay self-contained.
Do not assume the user can open this repository's internal design docs after installing it from the marketplace. Everything needed for setup, readiness, repair, and first-message verification should be explained here.
Install Boundary: Skill vs Hermes Binary
Always distinguish these two things before taking action:
- the NextClaw marketplace skill:
installed into the active workspace as
skills/hermes-runtime/SKILL.md - the Hermes executable:
the external runtime binary exposed as
hermes
Installing this skill does not install Hermes by itself.
The skill must detect whether hermes is already available and install or repair Hermes when it is not.
What This Skill Owns
- explain the correct product mental model
- install Hermes when missing
- detect and repair
hermes acp - write or repair
agents.runtimes.entries.hermes - verify that
Hermesappears as a formal session type - run a real first-message smoke
- diagnose and repair common failures
This skill does not redefine the runtime architecture. It operationalizes the already-locked product contract.
Required Mental Model
Always describe the system in this order:
- NextClaw owns the unified runtime registry.
Hermesis one runtime entry inside that registry.- The preferred first version of
Hermesis:type: "narp-stdio"wireDialect: "acp"command: "hermes"args: ["acp"]
- NextClaw owns
model / apiBase / apiKey / headers. - Hermes ACP consumes that route through the dedicated Hermes ACP bridge prepared by the Hermes setup/launcher path, not through kernel-side Hermes detection.
What ships with it
1 file 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.

hermes-runtime is a skill published in the GitHub repository Peiiii/nextclaw (262 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 2,258 once invoked, about $0.0002 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.
