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 | $0.00094 | $0.00807 |
| Opus 5 | $0.00047 | $0.00404 |
| Sonnet 5 | $0.00019 | $0.00161 |
| Haiku 4.5 | $0.00009 | $0.00081 |
Grade A, and why
agent-factory 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Factory
Create durable child Hermes agents from a permissioned mother agent.
Use this when the user wants a separate long-lived service agent with isolated Kubernetes namespace, PVC-backed Hermes state, optional child wallet, optional injected environment secrets, and optional x402 ServiceOffer.
Quick Start
python3 scripts/factory.py create medical-advisor \
--model antangelmed \
--skills medical-safety,privacy-filter,citations \
--objective "Answer medical education questions with emergency escalation and no diagnosis." \
--create-wallet \
--price 0.05 \
--pay-to 0xYourProviderWallet \
--network base-sepolia \
--register-name "Medical Advisor"
Multiple currencies / networks (one agent, one offer)
Use repeatable --accept instead of --price/--network to advertise several
payment options on a single offer (the buyer picks one). token=<symbol> pulls
the asset metadata from the built-in registry; for an unlisted token supply it
inline with asset=0x..,decimals=..,transfer=eip3009|permit2,eip712-name=..,eip712-version=..,symbol=..:
python3 scripts/factory.py create bankr-analyst \
--model openrouter/auto --skills bankr-token-analysis --create-wallet \
--accept token=OBOL,network=ethereum,price=10 \
--accept token=USDC,network=base,price=1,pay-to=0xColdVault \
--description "Paid token-analysis agent"
Each --accept may carry its own pay-to; otherwise it inherits --pay-to,
which defaults to the master Hermes agent's own wallet — so a sub-agent
needn't provision its own wallet just to take payment (pass --create-wallet
only when it genuinely needs to hold/sign funds). For an unlisted token the
asset=0x.. escape hatch needs only the address: decimals, symbol, and the
EIP-712 domain (eip712-name/eip712-version) are read from the chain
(EIP-5267) when omitted, and transfer defaults to permit2; the factory
errors and asks you to specify them if they can't be read. ERC-8004
registration uses the first option's network.
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.

agent-factory is a skill published in the GitHub repository ObolNetwork/obol-stack (11 stars, last pushed 3d ago), licensed Apache-2.0. It adds 94 tokens to every session and 807 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
