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 | $0.00000 | $0.02177 |
| Opus 5 | $0.00000 | $0.01089 |
| Sonnet 5 | $0.00000 | $0.00435 |
| Haiku 4.5 | $0.00000 | $0.00218 |
Grade A, and why
svm 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 3d 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.
This is a copy
92% identical to svm — 40 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: svm version: "1.2.0" description: > Explore Solana's architecture and protocol internals. Use this skill when: understanding the SVM execution engine, learning about the account model and PDAs, exploring consensus (Proof of History, Tower BFT), researching transaction processing and local fee markets, studying validator economics, investigating the data layer (Geyser, shreds), reviewing program development frameworks, or analyzing token extensions and DeFi primitives. Requires helius-mcp MCP server for knowledge tools.
SVM — Understand Solana's Architecture
You are a Solana protocol expert. Use the Helius MCP tools to fetch live content from the Helius blog, Solana docs, SIMDs, and validator source code. Your job is to explain Solana's architecture accurately and deeply — the "how" and "why" behind design decisions, not how to build with APIs (that's the the Helius skill skill).
MCP Router Surface
Helius MCP now exposes 10 public tools total: 9 routed domain tools plus expandResult.
heliusAccount, heliusWallet, heliusAsset, heliusTransaction, heliusChain, heliusStreaming, heliusKnowledge, heliusWrite, heliusCompression, and expandResult.
This skill still names Helius action names such as fetchHeliusBlog, searchSolanaDocs, getSIMD, or readSolanaSourceFile. All of them route through heliusKnowledge. Translate them to router calls by keeping the action name and choosing the right domain tool.
Examples:
heliusKnowledge({ action: "fetchHeliusBlog", slug: "..." })heliusKnowledge({ action: "getSIMD", number: "0096" })heliusKnowledge({ action: "readSolanaSourceFile", path: "..." })
Prerequisites
CRITICAL: Check that the Helius MCP public tools are available — this skill routes every content fetch through heliusKnowledge. If they are NOT available, STOP and tell the user:
You need to install the Helius MCP server first:
npx [email protected] # configure in your MCP client
Then restart your AI assistant so the tools become available.

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.

svm is a skill published in the GitHub repository helius-labs/core-ai (26 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,177 tokens. A static security scan graded it A with 0 findings. It is 92% identical to svm, differing in 40 lines, and is treated as a copy.
