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 | $0.00075 | $0.01147 |
| Opus 5.5 | $0.00030 | $0.00459 |
| Sonnet 5.5 | $0.00015 | $0.00229 |
| Haiku 4.5 | $0.00007 | $0.00115 |
Grade A, and why
utilia-solana-preflight 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 2mo 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Utilia Solana Preflight
Use the published [email protected] client. It signs exact x402 payments
locally and refuses any payment outside Solana mainnet USDC, Utilia's verified
receiver, or the hard $0.01 per-call ceiling.
Fastest wallet-managed call
Agents that already use AgentCash can make the lowest-cost live call without handling a private key directly:
npx -y agentcash@latest balance
npx -y agentcash@latest fetch https://api.utilia.ink/v1/fees/priority --yes
AgentCash creates and manages its own wallet on first use. The wallet must have
USDC before the paid call; balance reports the available funds and funding
accounts. The fetch command negotiates the x402 challenge and pays exactly
$0.002 for the response. Utilia never receives or controls the payer's key.
Prepare
Require one of:
export SOLANA_KEYPAIR_PATH=/absolute/path/to/low-balance-agent-wallet.json
Alternatively, provide SOLANA_PRIVATE_KEY through the agent's environment or
secret manager. Its value must be a base58-encoded 64-byte private key. Do not
place the value directly in a command, prompt, source file, or skill document.
Never print, log, paste, or transmit the private key. Prefer a dedicated automation wallet with only a small USDC balance and enough SOL for fees. If neither variable is set, ask the user to configure one; do not invent or search for credentials.
Verify the wallet and live service before the first paid call:
npx -y [email protected] doctor
Data handling
Treat every requested signature, mint, transaction, account address, public PDF, and public audio file as data sent to Utilia for processing. Do not submit private documents, private recordings, or data the user is not authorized to share. The client sends payment only after validating the receiver, network, asset, and per-call price ceiling.
Before a media call, confirm that the user approved sending the public URL or bytes to Utilia. The service processes PDF and audio content in memory and does not persist request or response bodies to disk. Standard access and settlement logs retain route, request, network, payer, and transaction metadata but not media bodies.
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.
