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 | $0.00195 | $0.02035 |
| Opus 5 | $0.00097 | $0.01018 |
| Sonnet 5 | $0.00039 | $0.00407 |
| Haiku 4.5 | $0.00019 | $0.00203 |
Grade A, and why
solana-rpc scanned grade A with 1 finding 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 12d 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.

Solana RPC Skill
Reference files:
references/core-methods.md— standard Solana JSON-RPC methods, parameters, response shapesreferences/helius-extensions.md— DAS API, Enhanced Transactions, Priority Fee, Sender, LaserStreamreferences/quicknode-extensions.md—qn_estimatePriorityFees, Metaplex DAS addon, Jitoreferences/patterns.md— batching, rate limits, resume, cost optimizationreferences/examples/— working Python scripts
🚨 Rule #1: use the provider's parsed/enhanced APIs when available
The biggest credit waste on Solana RPC is fetching raw data and parsing it yourself when the provider offers a parsed endpoint. Matrix:
| Task | Cheap option | Expensive / broken option |
|---|---|---|
| Wallet NFTs + tokens | Helius DAS getAssetsByOwner |
getTokenAccountsByOwner + metadata lookups |
| Complete tx history | Helius getTransactionsForAddress |
getSignaturesForAddress + N × getTransaction |
| Parsed DEX swap details | Helius Enhanced Tx or Solscan | getTransaction + manual program parsing |
| NFTs by collection | DAS getAssetsByGroup / searchAssets |
getProgramAccounts (expensive + slow) |
| Priority fee estimate | getPriorityFeeEstimate (Helius) or qn_estimatePriorityFees (QuickNode) |
getRecentPrioritizationFees (raw, needs math) |
| Compressed NFT history | DAS getSignaturesForAsset |
getSignaturesForAddress (doesn't work for cNFTs) |
When in doubt: check references/helius-extensions.md first — if Helius has a purpose-built endpoint, use it.
🚨 Rule #2: batch JSON-RPC requests
Single HTTP request can carry an array of JSON-RPC calls:
[
{"jsonrpc":"2.0","id":1,"method":"getTransaction","params":["sig1",{"encoding":"jsonParsed","maxSupportedTransactionVersion":0}]},
{"jsonrpc":"2.0","id":2,"method":"getTransaction","params":["sig2",{"encoding":"jsonParsed","maxSupportedTransactionVersion":0}]},
...up to ~100 items
]

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.

solana-rpc is a skill published in the GitHub repository Vo1ganin/crypto-claude-skills (2 stars, last pushed 22d ago), licensed MIT. It adds 195 tokens to every session and 2,035 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
