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.

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 | $0.00021 | $0.04405 |
| Opus 5 | $0.00010 | $0.02202 |
| Sonnet 5 | $0.00004 | $0.00881 |
| Haiku 4.5 | $0.00002 | $0.00441 |
Grade C, and why
xurl 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
`xurl` is the X developer platform's official CLI for the X API. It supports shortcut commands for common actions AND raw curl-style access to any v2 endpoint. All commands return JSON to stdout. Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 437 lines — stays where its author put it; the contents beside it link to each section on GitHub.
xurl — X (Twitter) API via the Official CLI
xurl is the X developer platform's official CLI for the X API. It supports shortcut commands for common actions AND raw curl-style access to any v2 endpoint. All commands return JSON to stdout.
Use this skill for:
- posting, replying, quoting, deleting posts
- searching for raw posts (actual post JSON with IDs you can engage with) and reading timelines/mentions
- liking, reposting, bookmarking
- following, unfollowing, blocking, muting
- direct messages
- media uploads (images and video)
- raw access to any X API v2 endpoint
- multi-app / multi-account workflows
This skill replaces the older xitter skill (which wrapped a third-party Python CLI). xurl is maintained by the X developer platform team, supports OAuth 2.0 PKCE with auto-refresh, and covers a substantially larger API surface.
Secret Safety (MANDATORY)
Critical rules when operating inside an agent/LLM session:
- Never read, print, parse, summarize, upload, or send
~/.xurlto LLM context. - Never ask the user to paste credentials/tokens into chat.
- The user must fill
~/.xurlwith secrets manually on their own machine. In Docker, this must be the~seen by Hermes tool subprocesses; see the Docker note below. - Never recommend or execute auth commands with inline secrets in agent sessions.
- Never use
--verbose/-vin agent sessions — it can expose auth headers/tokens. - To verify credentials exist, only use:
xurl auth status.
Forbidden flags in agent commands (they accept inline secrets):
--bearer-token, --consumer-key, --consumer-secret, --access-token, --token-secret, --client-id, --client-secret
App credential registration and credential rotation must be done by the user manually, outside the agent session. After credentials are registered, the user authenticates with xurl auth oauth2 — also outside the agent session. Tokens persist to ~/.xurl in YAML. Each app has isolated tokens. OAuth 2.0 tokens auto-refresh.
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.

xurl is a skill published in the GitHub repository NousResearch/hermes-agent (242,680 stars, last pushed today), licensed MIT. It adds 21 tokens to every session and 4,405 once invoked, about $0.0001 per session on Opus 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.
