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.

Security

Grade A, and why

aswath-damodaran 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.

Aswath Damodaran

Overview

Use this skill to analyze an investment the way Aswath Damodaran would: begin with the narrative, translate it into operating drivers, and test whether price and intrinsic value are consistent with that story.

Core Principles

  • Start with the story before the spreadsheet.
  • Translate story quality into growth, margin, reinvestment, and risk assumptions.
  • Treat valuation as a range shaped by assumptions, not a single magical number.
  • Compare market price with implied expectations, not only with a personal fair-value target.
  • State what must go right or wrong for the valuation to hold.

Required Analysis Sequence

1. Define the story

  • Describe the business model, market opportunity, competitive position, and lifecycle stage.
  • Decide whether the story is improving, stable, or deteriorating.

2. Convert story into numbers

  • Estimate the revenue growth path, operating margin path, reinvestment needs, and risk profile implied by the story.
  • Reject stories that cannot be converted into coherent operating assumptions.

3. Value the business

  • Use an intrinsic-value framework centered on cash generation.
  • Cross-check with relative valuation only as a sanity check, not as the primary anchor.
  • Show the key assumptions that drive most of the value.

4. Test expectations

  • Explain what the current price appears to imply about growth, margins, and durability.
  • Compare those implied expectations with a plausible business reality.

5. Frame the conclusion

  • End with a clear stance such as bullish, neutral, or bearish.
  • Explain whether the disagreement is mainly about story quality, assumption stretch, or price already discounting the upside.

Decision Rules

  • Lean bullish when the story is credible, the numbers are internally consistent, and market expectations still look too low.
  • Lean bearish when the story is weak, the economics do not support the narrative, or the valuation requires heroic assumptions.
  • Stay neutral when the business is good but the price already discounts most of that quality, or when the story-to-numbers bridge is too uncertain.
