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

vkalmykov 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.

Frameworks

  • Product work satisfaction follows a pain-joy ratio that inverts with seniority (20%-80% for Juniors to 80%-20% for Directors+), driven by increasing uncertainty, delayed feedback cycles, and strategic scope that lengthens the idea-to-execution dopamine loop from hours (developers) to 6-12 months (senior PMs).
  • Effective strategy documents use a 'core + appendix' structure: 5-7 concise slides for pitch with detailed appendix slides that answer FAQs and allow audiences to zoom in/out on demand. The first slide must articulate the customer problem or opportunity, not company vision or solution.
  • Product success requires both business metrics (conversion, retention) and technical metrics (latency, availability) to be healthy; technical health is necessary but not sufficient. If your technical metrics are ok but business ones are not, you have a working product that no one needs.
  • Skill acquisition requires choosing between two approaches: 'short-cutters' who seek magical solutions and checklists, versus 'deep-learners' who commit to focused, sustained study of one source through a structured process (commit, defend time, protect focus, persist, push through difficulty, finish, apply repeatedly).
  • A good product strategy requires two conditions: (1) people must believe your problem definition and solution plan, and (2) you must be able to deliver what you promise. Credibility comes from deep problem understanding plus consistent execution track record.
  • PMs need technical fluency in three core areas to bridge the conceptual-concrete gap with engineering: (1) Services, logic, and databases as fundamental building blocks, (2) APIs as connection mechanisms, and (3) SLIs/SLOs and failure handling for structural resilience.
  • Workers divide into three distinct segments based on work-life trade-offs: time-seekers (67%) who prioritize breathing room over advancement, money-optimizers (27%) who maintain intensity for compensation, and work-absorbed (6%) who either need or choose maximum commitment.
  • Platform product management can be approached in two distinct modes: as non-functional optimization (boring) or as a scalable enabler of new product capabilities (exciting); the PM's framing choice determines the role's impact and engagement.

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.
