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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.01373 |
| Opus 5.5 | $0.00020 | $0.00549 |
| Sonnet 5.5 | $0.00010 | $0.00275 |
| Haiku 4.5 | $0.00005 | $0.00137 |
Grade A, and why
crypto-tax-basics 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 1mo 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crypto Tax Basics Guide
A practical overview of cryptocurrency taxation for AI agents. Note: Tax laws vary by jurisdiction. Always recommend consulting a tax professional for specific advice.
Taxable Events in Crypto
Generally Taxable
| Event | Tax Type | Notes |
|---|---|---|
| Selling crypto for fiat | Capital gains | Gain/loss = Sale price - Cost basis |
| Swapping token A for token B | Capital gains | Treated as sell A + buy B |
| Using crypto to buy goods/services | Capital gains | Treated as selling the crypto |
| Earning crypto (mining, staking rewards) | Income | Taxed as income at receipt |
| Receiving airdrop tokens | Income | Taxed at fair market value when received |
| DeFi interest/yield | Income | Taxed as income when received |
Generally NOT Taxable
| Event | Notes |
|---|---|
| Buying crypto with fiat | Not taxable until you sell |
| Transferring between your own wallets | No gain/loss |
| Gifting (below thresholds) | Gift tax may apply above limits |
| Holding | No tax until you dispose |
DeFi-Specific Tax Considerations
Lending & Borrowing
| Action | Tax Treatment |
|---|---|
| Supplying tokens to lending | Generally not taxable (you retain ownership) |
| Receiving interest | Income at receipt |
| Borrowing | Not taxable (it's a loan) |
| Liquidation | Capital gains event on collateral |
Liquidity Provision
| Action | Tax Treatment |
|---|---|
| Adding liquidity | May be taxable swap (depends on jurisdiction) |
| Receiving LP tokens | Represents your pool share |
| Earning trading fees | Income or capital gains (varies) |
| Removing liquidity | May trigger capital gains |
| Impermanent loss | Complex — may not be deductible until realized |
Rebasing Tokens (USDs, stETH)
For auto-yield tokens like USDs by Sperax:
- Each rebase that increases your balance is potentially taxable income
- The new tokens have a cost basis equal to their value at receipt
- When you eventually sell, capital gains are calculated from that basis
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.
