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 | $0.01458 | $0.01458 |
| Opus 5 | $0.00729 | $0.00729 |
| Sonnet 5 | $0.00292 | $0.00292 |
| Haiku 4.5 | $0.00146 | $0.00146 |
Grade A, and why
solana-vault-standard CLAUDE.md 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.
How it starts
The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solana Tokenized Vault Standard
Native port of ERC-4626 to Solana. 14 programs (SVS-1 through SVS-12 + mock-oracle + mock-sas) implementing tokenized vaults with shares representing proportional ownership of underlying SPL tokens.

Communication Style
- No filler phrases ("I get it", "Awesome, here's what I'll do", "Great question")
- Direct, efficient responses
- Code first, explanations when needed
- Admit uncertainty rather than guess
Branch Workflow
All new work: git checkout -b <type>/<scope>-<description>-<DD-MM-YYYY>. Use /quick-commit for automation.
Mandatory Workflow
Every program change:
- Build:
anchor buildorcargo build-sbf - Format:
cargo fmt - Lint:
cargo clippy -- -W clippy::all - Test: Unit + integration + fuzz
- Deploy: Devnet first, mainnet with explicit confirmation
Security Principles
NEVER:
- Deploy to mainnet without explicit user confirmation
- Use unchecked arithmetic in programs
- Skip account validation
- Use
unwrap()in program code - Recalculate PDA bumps on every call
- Trust CPI return data without validating target program ID
- Use
init_if_neededon PDA data accounts (reinit attack). Exception: ATAs withassociated_tokenconstraint - Allow share price manipulation via direct token transfers
- Skip virtual shares/assets offset (inflation attack vector)
- Round in favor of user over vault on entry/exit
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.
