oh-my-hermes is an operating layer for Hermes Agent that organizes requests into workflows for planning, research, creation, coding handoffs, operations, and project memory. Hermes users run these workflows through the desktop app, CLI, or messenger app, while the catalogue add-ons extend its native capabilities.
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 | $0.00110 | $0.02715 |
| Opus 5.5 | $0.00044 | $0.01086 |
| Sonnet 5.5 | $0.00022 | $0.00543 |
| Haiku 4.5 | $0.00011 | $0.00271 |
Grade A, and why
omh-spend-gate 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spend Gate
This is an OMH spend-gate workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
Why This Exists
spend-gate exists because money movement had at most one native guard, on one rail: where Hermes' saved-card fill is present it asks before filling a card and refuses when nobody can confirm, while an HTTP 402 call, a wallet transfer, a booking, or a paid data endpoint had no pre-spend check, no receipt rule, and no cap. omh-provider-profile-posture claims no payment at all.
First Steps
- Check that a person can answer in this session; in a scheduled, webhook, API-server, single-query, background-worker, or subagent run, prepare the card and stop before any payment surface.
- Read the quote from its source and fill the pre-spend card from it, the cap included, before anything is submitted.
Do Not Use When
- The page task moves no money -- open a URL, log in, fill a form, capture blockers.
- Users report a payment failure in the product and the ask is to sort those reports; use
omh-feedback-triage. - The ask is budget vs actual, a budget variance, or the month-end close; use
omh-finance-analysis. - The ask is a provider profile's posture or whether its secrets are present, with nothing bought; use
omh-provider-profile-posture.
Examples
Good example:
- Prompt: the api answered 402 payment required, pay it so we get the dataset
- Expected behavior: Read the amount, currency, payee, and method from the 402 challenge, show pre_spend_card/v1 with the cap and what remains of it, wait for the person's typed yes, pay through the client they installed, and report done only with the receipt header and the amount charged.
- Why: A 402 call spends the moment it is retried with a credential; the card is the one point where the person sees the price.
Bad example:
- Prompt: the checkout timed out, just click pay again
- Expected behavior: Mark the first charge unknown, look for it in the order history or the card activity, and show a new card only once it is shown absent.
- Why: A second click after a success nobody saw is a double charge.
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.

omh-spend-gate is a skill published in the GitHub repository rlaope/oh-my-hermes (3,392 stars, last pushed today), licensed MIT. It adds 110 tokens to every session and 2,715 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-15.
