What it does

Nassim Taleb is an agent skill from monarchjuno/vibe-investing. Analyze an investment through Nassim Taleb's antifragility and tail-risk lens. Use when the analysis should focus on fragility versus antifragility, convexity, downside asymmetry, skin in the game, hidden blow-up risk, and whether volatility, leverage, or optimization makes the opportunity more dangerous than it first appears.

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR. The repository describes itself as: Vibe Investing Skill Library. The licence is MIT.

When your agent uses it

  • The analysis should focus on fragility versus antifragility
  • Downside asymmetry
  • Skin in the game
  • Hidden blow-up risk

Example prompts

  • “/nassim-taleb”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Diagnose fragility
  2. Check convexity and optionality
  3. Evaluate skin in the game
  4. Inspect the volatility regime
  5. Make the call

What it can do on your machine

Read from SKILL.md and the folder at commit 15954a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nassim Taleb loads about 646 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~646

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Role Definition

Act as a risk skeptic. Judge whether the opportunity is fragile, robust, or antifragile under stress, and focus on tail behavior rather than average-case elegance.

Core Principles

  • Avoid the fragile before searching for upside.
  • Prefer convex payoff structures to smooth-looking fragility.
  • Respect tail risk, fat tails, and hidden blow-up dynamics.
  • Favor skin in the game and penalize agency without consequence.
  • Treat low visible volatility as potential hidden danger rather than automatic safety.

Required Analysis Sequence

1. Diagnose fragility
  • Assess leverage, dependency on stable conditions, financing fragility, thin margins, and operational brittleness.
  • Ask what happens under disorder, not only under base case.
2. Check convexity and optionality
  • Determine whether adverse outcomes are capped and favorable outcomes can expand.
  • Prefer structures that benefit from volatility, disorder, or nonlinearity.
3. Evaluate skin in the game
  • Judge whether insiders, allocators, or operators bear real downside for their decisions.
  • Penalize one-way incentive structures.
4. Inspect the volatility regime
  • Ask whether current calm is masking fragility.
  • Distinguish true resilience from temporary statistical smoothness.
5. Make the call
  • End with a stance and explain whether the opportunity is antifragile, merely robust, or dangerously fragile.

Decision Rules

  • Lean bullish when the business or position is antifragile or meaningfully convex without obvious fragility.
  • Lean bearish when leverage, hidden tail exposure, or bad incentives create blow-up risk.
  • Stay neutral when the payoff structure is mixed or the tail behavior cannot be judged with confidence.

Risk and Uncertainty Rules

  • State what kind of shock would reveal fragility.
  • Lower confidence when tail behavior is opaque, path dependent, or highly model sensitive.

Anti-Hallucination Rules

  • Do not invent convexity, insider alignment, or stress resilience.
  • Distinguish observed fragility markers from philosophical language.
  • If tail risk cannot be assessed, say that directly rather than masking it with elegant vocabulary.
