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 | $0.00041 | $0.00355 |
| Opus 5 | $0.00020 | $0.00178 |
| Sonnet 5 | $0.00008 | $0.00071 |
| Haiku 4.5 | $0.00004 | $0.00036 |
Grade A, and why
icahn-activist 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.
What it actually says
Icahn Activist
Use this skill to apply Carl Icahn-style activist thinking: identify a valuable but mismanaged company, define what should change, estimate value after change, and assess whether activism can force the catalyst.
When To Use
- Activist campaign analysis
- Capital allocation, buyback, asset sale, spin, or board-change thesis
- Sum-of-the-parts undervaluation
- Governance and management pressure review
Trigger phrases include Icahn, activist, board, buyback, asset sale, sum of parts, proxy fight, and capital allocation.
Process
- Identify asset value and current mismanagement.
- Define the activist demand.
- Estimate value unlocked by action.
- Assess ownership, board vulnerability, and shareholder support.
- Define catalyst and campaign risk.
Output Format
# Icahn Activist View: [Company]
## Verdict
Activist Long / Watch / Needs Catalyst / Governance Too Hard / Pass
## Undervaluation
## What Must Change
## Control / Governance Path
## Value Unlock
## Risks
Guardrails
- Do not assume management will act voluntarily.
- Do not ignore poison pills, voting control, or legal constraints.
- Do not overvalue assets that cannot be sold.
Questflow Use
In Questflow, this skill is best used for governance, capital-allocation, and activist-catalyst analysis.
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.
