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.

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 | $0.02288 |
| Opus 5.5 | $0.00008 | $0.00915 |
| Sonnet 5.5 | $0.00004 | $0.00458 |
| Haiku 4.5 | $0.00002 | $0.00229 |
Grade A, and why
evm 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 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
(urllib, json, argparse, threading). How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EVM Blockchain Skill
Query EVM-compatible blockchain data across 8 chains with USD pricing. 14 commands: wallet portfolio, token info, transactions, activity, gas tracker, network stats, price lookup, multi-chain scan, whale detection, ENS resolution, allowance checker, contract inspector, and transaction decoder.
Supports 8 chains: Ethereum, BNB Chain (BSC), Base, Arbitrum One, Polygon, Optimism, Avalanche (C-Chain), zkSync Era.
No API key needed. Zero external dependencies — Python standard library only (urllib, json, argparse, threading).
Supersedes the standalone
baseskill. Base-specific tokens (AERO, DEGEN, TOSHI, BRETT, WELL, cbETH, cbBTC, wstETH, rETH) and all Base RPC functionality previously living underoptional-skills/blockchain/base/have been folded into this skill. Pass--chain baseto any command for Base coverage.
When to Use
- User asks for a wallet balance or portfolio on any EVM chain
- User wants to check the same wallet across ALL chains at once
- User wants to inspect a transaction by hash (or decode what it did)
- User wants ERC-20 token metadata, price, supply, or market cap
- User wants recent transaction history for an address
- User wants current gas prices or to compare fees across chains
- User wants to find large whale transfers in recent blocks
- User asks to resolve an ENS name (vitalik.eth) or reverse-lookup an address
- User wants to check if a contract has dangerous token approvals
- User wants to inspect a smart contract (proxy? ERC-20? ERC-721? bytecode size?)
- User wants to compare gas costs across chains before a transaction
Prerequisites
Python 3.8+ standard library only. No pip installs required. Pricing: CoinGecko free API (rate-limited, ~10-30 req/min). ENS: ensideas.com public API. Tx decoding: 4byte.directory public API.
Override RPC endpoint: export EVM_RPC_URL=https://your-rpc.com

Quick Reference
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.

evm is a skill published in the GitHub repository NousResearch/hermes-agent (255,268 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 2,288 once invoked, about $0.0001 per session on Opus 5.5. 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.
