Investor Skills is an open-source library that organizes investing judgment—such as evaluating opportunities, managing risk, and acting under uncertainty—into structured, reusable instructions for people and AI finance agents. It is designed for studying and applying investment approaches, including inside Questflow and other agent tools. The catalogue includes portable skill packages from the library.
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 | $0.00056 | $0.00968 |
| Opus 5 | $0.00028 | $0.00484 |
| Sonnet 5 | $0.00011 | $0.00194 |
| Haiku 4.5 | $0.00006 | $0.00097 |
Grade A, and why
grayscale-crypto-sectors 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 11d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Grayscale Crypto Sectors
Use this skill to apply Grayscale Research's public judgment system: classify first, then ask whether the token is index-eligible, whether usage/fees support the use case, and whether valuation vs its Crypto Sector still prices the theme as a rounding error.
When To Use
Use this skill when the user asks for:
- Grayscale, Crypto Sectors, FTSE/Grayscale indexes, or a Grayscale Top 20
- Zcash / ZEC / ZCSH / privacy-coin institutionalization
- Whether a token belongs in Currencies, Smart Contract Platforms, Financials, Consumer & Culture, Utilities & Services, or AI
- Sector-share valuation vs replacing Bitcoin
- Crypto ETP, trust, NAV premium/discount, or ETF-conversion structure
- Institutional access: custody, listing, legal classification, creation/redemption
Trigger phrases include Grayscale, Crypto Sectors, ZCSH, Zcash, ZEC, privacy as money, sector share, FTSE Grayscale, crypto ETP, and trust premium/discount.
Do Not Use When
- The request is a memecoin attention trade with no sector use case. Use
ansem-crypto. - The user wants protocol-mechanism or MEV design review. Use
paradigm-crypto-research. - The user wants funding/leverage cycle timing. Use
arthur-hayes-liquidity. - Critical market-cap, sector, fee, or product-wrapper data is missing and a live verdict is requested.
- The user wants guaranteed returns or unbounded leverage.
Inputs Needed
- Token, theme, or Grayscale product ticker
- Crypto Sector assignment and nearest sector peers
- Circulating market cap, sector market cap, and implied sector share
- Users / active addresses, transactions, and fees
- Token supply inflation and unlocks
- Upcoming catalysts: upgrades, legislation, ETP/ETF filings
- For listed products: NAV, market price, premium/discount, creation/redemption status
- Time horizon and whether this is a core monetary sleeve or a satellite theme
If live data matters and is missing, say what is missing and give a provisional sector memo rather than a false-precision target.
What ships with it
1 file 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.
