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

christensen-jobs 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 12d 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 to Use This Skill

  • Without arguments — load core frameworks for reference
  • With a topic — ask about forces of progress, nonconsumption, job spec, the three fallacies; I find and read the relevant chapter
  • With chapter — ask for ch05; I load that specific chapter
  • Browse — ask "what chapters do you have?" to see the full index

When you ask about a topic not in Core Frameworks below, I read the relevant chapter file before answering.


Core Frameworks & Mental Models

The central question"What job did you hire that product to do?" Customers don't buy products; they hire them to make progress, and fire them when something does the job better.

The Job to Be Done (the definition)A job is the progress that a person is trying to make in a particular circumstance. Three load-bearing words:

  • Progress — movement toward a goal/aspiration. A job is never just a function; it's a verb-driven struggle, not a product category or a customer attribute.
  • Circumstance — the job is defined by the situation, not by customer demographics, product attributes, technology, or trends. "I'm a 40-year-old male" doesn't cause a purchase; "I have a long, boring morning commute and one free hand" does. The circumstance is the fundamental unit of innovation work — not the customer.
  • Functional + Social + Emotional dimensions — every job has all three; the social and emotional are often heavier than the functional. Miss them and you miss the job.

Jobs are stable; solutions churn. The job ("get me from A to B reliably") barely changes over decades; the products hired to do it (horse → car → Uber) change constantly. Innovate against the job, not the current solution.

The Milk Shake Dilemma — When you study the product (improve the shake), you optimize the wrong thing. When you study the job (the morning shake is hired to make a boring commute survivable with one hand; the afternoon shake is a different job — a dad placating a kid), you see what to build and what you really compete with. Same product, two different jobs.

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.
