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 | $0.00074 | $0.00540 |
| Opus 5 | $0.00037 | $0.00270 |
| Sonnet 5 | $0.00015 | $0.00108 |
| Haiku 4.5 | $0.00007 | $0.00054 |
Grade A, and why
utilia-solana-transaction-diagnosis 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 11d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Utilia Solana Transaction Diagnosis
Turn one Solana signature into a support-ready explanation. Prefer the wallet-managed AgentCash route; it checks the quote before paying and does not send a private key to Utilia.
Validate the request
Require one Base58 Solana signature between 64 and 88 characters. A transaction signature is public on-chain data, not a wallet secret. Never ask for a seed phrase or private key.
Set the call URL by replacing YOUR_SIGNATURE:
https://api.utilia.ink/base/v1/transaction/YOUR_SIGNATURE
Check before paying
Inspect the live x402 quote without settling:
npx -y agentcash@latest check \
"https://api.utilia.ink/base/v1/transaction/YOUR_SIGNATURE"
Proceed only when the quote identifies the expected Utilia URL, Base network,
USDC asset, and an exact price no higher than $0.004.
If the user has not already authorized this specific paid diagnosis, state that
the next command spends exactly $0.004 USDC and ask for confirmation. Do not
pay from an operator wallet to simulate customer demand.
Diagnose
After payment authorization, run:
npx -y agentcash@latest fetch \
"https://api.utilia.ink/base/v1/transaction/YOUR_SIGNATURE" --yes
AgentCash manages the wallet, signs the x402 payment locally, retries the request,
and returns the response. If its wallet is unfunded, report the funding account
shown by npx -y agentcash@latest balance; do not search for other credentials.
Explain the evidence
Return a compact diagnosis containing:
- whether the signature landed and whether execution succeeded;
- slot, block time, fee, compute units, and confirmation state when available;
- meaningful SOL and token balance deltas;
- the relevant program-log failure, without dumping unrelated logs;
- Utilia's failure category and suggested next action;
- the settled price and payment receipt reported by AgentCash.
Separate observed evidence from inference. Do not claim that a retry or simulation guarantees future execution because block state, balances, and market conditions can change.
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.

utilia-solana-transaction-diagnosis is a skill published in the GitHub repository mohamedkuch/utilia-solana-agent (0 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 540 once invoked, about $0.0004 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 2026-08-31.
