Token cost

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

thinking-in-bets 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

Domain Context

This skill implements a proven product management framework. The approach combines best practices from industry leaders and is designed for practical application in day-to-day PM work.

Input Requirements

  • Context about your product, feature, or problem
  • Relevant data, research, or constraints (recommended but optional)
  • Clear articulation of what you're trying to achieve

Thinking in Bets

What It Is

Thinking in Bets is a framework for improving decision quality by separating decisions from outcomes. The core insight: a good decision can have a bad outcome, and a bad decision can have a good outcome—luck is always involved.

Most people judge decisions by their outcomes (called "resulting"). This is backwards. You can only control the quality of your decision, not the outcome.

The key shifts:

  • Move from "Was I right?" to "Was my thinking process good?"
  • Move from "What happened?" to "What did I know at the time?"
  • Move from implicit assumptions to explicit, testable beliefs

When to Use It

Use Thinking in Bets when you need to:

  • Evaluate past decisions without outcome bias clouding judgment
  • Make decisions under uncertainty where luck will influence results
  • Improve team decision-making in meetings and planning
  • Set up pre-mortems and kill criteria for projects
  • Shorten feedback loops on decisions with delayed outcomes
  • Reduce cognitive biases like overconfidence, hindsight bias, and sunk cost
  • Run better meetings that surface true opinions, not groupthink

When Not to Use It

  • The decision is trivial with low stakes
  • You have perfect information (rare)
  • You're looking for permission to take a risk you've already decided on

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.
