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 | $0.00025 | $0.02750 |
| Opus 5 | $0.00013 | $0.01375 |
| Sonnet 5 | $0.00005 | $0.00550 |
| Haiku 4.5 | $0.00003 | $0.00275 |
Grade A, and why
tax-loss-harvesting 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 12d 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.

Tax-Loss Harvesting
Identify, score, and plan tax-loss harvesting (TLH) opportunities across a crypto portfolio. This skill covers unrealized-loss ranking, net-benefit calculation, wash sale compliance, annual loss carryforward tracking, and year-end "use it or lose it" strategies.
Disclaimer: This skill provides informational analysis only. It is NOT tax advice. Tax rules vary by jurisdiction and change frequently. Consult a qualified tax professional before making any tax-related trading decisions.
How Tax-Loss Harvesting Works
Tax-loss harvesting is the practice of intentionally realizing investment losses to offset realized capital gains, thereby reducing your current-year tax liability.
Core Mechanism
- Identify positions with unrealized losses in your portfolio.
- Sell those positions to realize the loss.
- Offset realized gains with the harvested loss, reducing taxable income.
- Optionally re-enter a similar (but not "substantially identical") position to maintain market exposure.
Short-Term vs Long-Term
| Holding Period | Classification | Typical Tax Rate |
|---|---|---|
| < 1 year | Short-term capital gain/loss | Ordinary income rate |
| >= 1 year | Long-term capital gain/loss | Preferential rate (0-20%) |
Short-term losses first offset short-term gains; long-term losses first offset long-term gains. Remaining net losses cross over to offset the other category.
Annual Loss Deduction Limit
If total net losses exceed total gains, the excess is deductible against ordinary income up to $3,000 per year ($1,500 if married filing separately). Any remaining loss carries forward indefinitely to future tax years.
Ranking Unrealized Losses
Not all unrealized losses are equally valuable to harvest. This skill scores each opportunity on four dimensions:
1. Loss Magnitude
Larger dollar losses provide more tax savings. The raw loss is the difference between current market value and cost 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.
