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

change-one-thing 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 10d 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.

Reading Your Career History

@$1


The Time Travel Exercise

You can travel back in time to any point in your career and change only ONE thing. What's the single most impactful non-obvious change, at what specific moment, and why?

Scope & Constraints

EXCLUDE (too obvious):

  • Simple salary negotiations at current employer
  • Binary job acceptance/rejection without deeper analysis
  • Tenure decisions without strategic context
  • Credential timing without market positioning analysis
  • Simple promotion pursuit decisions

RECONSIDER (may be non-obvious when analyzed deeply):

  • Geographic/geopolitical positioning decisions (where you lived/worked)
  • Industry/company moves if they represent inflection points
  • Repatriation timing and destination choices
  • Market timing decisions with compounding effects

INCLUDE (non-obvious, high-compounding):

  • Skill development sequencing or parallel building choices
  • Relationship cultivation patterns (mentors, sponsors, peers, adjacent domains)
  • Platform/tool adoption timing (early personal vs. late enterprise adoption)
  • Intellectual property distribution decisions (internal use vs. public amplification)
  • Communication habits or visibility systems (writing, speaking, teaching cadence)
  • Knowledge management infrastructure (documentation, frameworks, tooling)
  • Cross-domain bridge building (adjacent industries, hybrid skill intersections)
  • Side projects or optionality creation (consulting, teaching, open source, thought leadership)
  • Learning meta-skills vs. domain skills (teaching ability, product sense, storytelling)
  • Strategic positioning vs. tactical execution (brand, reputation, network effects)

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.
