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 | $0.00066 | $0.00959 |
| Opus 5 | $0.00033 | $0.00479 |
| Sonnet 5 | $0.00013 | $0.00192 |
| Haiku 4.5 | $0.00007 | $0.00096 |
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 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.
This is a copy
94% identical to tax-loss-harvesting — 7 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.

Tax-Loss Harvesting
Workflow
Step 1: Identify Candidates
Scan taxable accounts for positions with unrealized losses:
| Security | Asset Class | Cost Basis | Current Value | Unrealized Loss | Holding Period | % Loss |
|---|---|---|---|---|---|---|
| ST / LT |
Prioritize by:
- Largest absolute loss (biggest tax benefit)
- Short-term losses first (offset short-term gains taxed at ordinary income rates)
- Positions with the largest % loss (less likely to recover quickly)
Step 2: Gain/Loss Budget
Calculate the client's tax situation:
| Category | Amount |
|---|---|
| Realized short-term gains YTD | |
| Realized long-term gains YTD | |
| Realized losses YTD | |
| Net gain/(loss) position | |
| Carryforward losses from prior years | |
| Target harvesting amount |
Tax savings estimate:
- Short-term losses × marginal ordinary income rate
- Long-term losses × capital gains rate
- Up to $3,000 net loss deduction against ordinary income
- Excess carries forward
Step 3: Replacement Securities
For each harvest candidate, suggest a replacement that:
- Maintains similar market exposure (same asset class, sector, geography)
- Is NOT "substantially identical" (wash sale rule)
- Has similar risk/return characteristics
| Sell | Replace With | Reason | Tracking Error Risk |
|---|---|---|---|
| SPDR S&P 500 (SPY) | iShares Core S&P 500 (IVV) | Same index, different fund family | Minimal |
| Vanguard Total Intl (VXUS) | iShares MSCI ACWI ex-US (ACWX) | Similar exposure, different index | Low |
| Individual stock ABC | Sector ETF (XLK) | Broader exposure, no wash sale risk | Moderate |
Step 4: Wash Sale Check
Before executing, verify no wash sales:
- Check ALL accounts in the household (taxable, IRA, Roth, spouse accounts)
- 30-day lookback: Did we buy substantially identical securities in the last 30 days?
- 30-day forward: Block repurchase of the same security for 30 days
- Check for dividend reinvestment plans (DRIPs) that could trigger wash sales
- Document the wash sale window for each trade
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.
