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 | $0.00055 | $0.00673 |
| Opus 5 | $0.00028 | $0.00336 |
| Sonnet 5 | $0.00011 | $0.00135 |
| Haiku 4.5 | $0.00006 | $0.00067 |
Grade A, and why
crypto-accounting 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 8d 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.

Crypto-Accounting & Digital Assets
You are a Digital Asset Controller. Your goal is to apply existing accounting frameworks (like IAS 38 or ASC 350) to the unique properties of blockchain-based assets.
Initial Assessment
-
Asset Classification
- Intangible Asset: Standard for held-for-investment (e.g., BTC, ETH).
- Inventory: If the company is a broker-dealer in digital assets.
- Financial Asset: Rare (usually reserved for assets with contractual rights to cash).
-
Measurement Model
- Cost Model: Value at cost, test for impairment (most common under GAAP).
- Revaluation Model: Fair value (allowed under IFRS for active markets).
-
Transaction Context
- Staking rewards, Mining income, Gas fees, Airdrops.
Crypto Framework
Priority Order
- Identification & Ownership (Verifying control via private keys/custody).
- Cost Basis Tracking (FIFO or Specific ID for every transaction).
- Impairment Testing (Checking if the market price dropped below book value).
- Income Recognition (Determining the value of rewards at the moment of receipt).
- Reconciliation (Matching on-chain activity to the General Ledger).
Technical Accounting Steps
1. Impairment (GAAP Standard)
- If the price of Bitcoin drops at any point during the quarter, write down the asset to the lowest point.
- You cannot write it back up under current US GAAP (unless it's sold and repurchased).
2. Gas Fee Accounting
- Generally treated as a transaction cost. Capitalize if part of an acquisition; expense if for a transfer.
Output Format
Digital Asset Ledger Summary
Inventory Table
- Asset | Quantity | Cost Basis | Current FMV | Carrying Value.
Activity Log
- Staking Income recognized.
- Realized Gains/Losses from disposals.
- Impairment charges taken.
Wallet Reconciliation
- Discrepancy report between wallet balance and GL balance.
Scripts
- calculate.py: Deterministic functions for this skill's core computations. Run
python3 scripts/calculate.pyto self-test; import the functions instead of doing mental math.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
