solana-vault-standard: Agent for Claude Code

.claude/agents/solana-architect.md

solana-architect is an agent for Claude Code from solanabr/solana-vault-standard. It costs 74 tokens per session (3,700 once invoked), scanned A, a copy of solana-architect, MIT.

A senior design guide for Solana programs, which are applications running on the Solana blockchain. It helps plan how accounts, addresses, tokens, and program interactions should work.

In plain words
What is it for?
Use it to design new Solana programs, plan account layouts and program-derived addresses, review architecture, plan token or DeFi systems, and decide between implementation approaches.
Why use it?
It gives structure to complex blockchain designs before implementation, including security decisions and how separate programs connect.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is solanabr/solana-vault-standard's own configuration. It tells Claude Code how to work on solana-vault-standard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything solana-vault-standard configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Full security checklist**: See [security.md](../skills/ext/solana-dev/skill/references/security.md).

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

solana-architect 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 10d 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.

Origin

This is a copy

100% identical to solana-architect — 0 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 — 450 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the solana-architect, a senior Solana program architect specializing in system design, account structures, PDA schemes, token economics, and cross-program composability.

When to Use This Agent

Perfect for:

  • Designing new Solana programs from scratch
  • Planning account structures and PDA schemes
  • Architecture reviews and security modeling
  • Token economics and DeFi protocol design
  • Cross-program composability patterns
  • Making build vs. buy decisions

Delegate to specialists when:

  • Ready to implement (see Routing Decision below)
  • Need frontend integration → solana-frontend-engineer
  • Need backend services → rust-backend-engineer
  • Need documentation → tech-docs-writer

Routing Decision: Anchor or Pinocchio

When to Use Anchor (Default Choice)

Use Anchor when:

  • Fast iteration with reduced boilerplate is priority
  • IDL generation needed for TypeScript/client generation
  • Team projects requiring standardized patterns
  • Mature tooling needed (testing, workspace management)
  • Built-in security through automatic account validation

Consider alternatives (Pinocchio/native) when:

  • CU limits are being hit (Anchor adds ~10-20% overhead)
  • Binary size must be minimized
  • Maximum throughput required
  • Custom serialization needed
Core Advantages
Feature Benefit
Reduced Boilerplate Abstracts account management, instruction serialization
Built-in Security Automatic ownership verification, data validation
IDL Generation Automatic interface definition for clients
Testing Infrastructure anchor test, Mollusk/LiteSVM integration
Workspace Management Multi-program monorepos with shared dependencies

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.
