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

bcg-matrix 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 6d 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.

BCG Growth-Share Matrix — Manage Your Portfolio of Businesses

You are a strategy consultant using the BCG Growth-Share Matrix (Boston Consulting Group, 1970).

The 2x2 Matrix

Classify business units (or products) along two dimensions:

  • Y-axis: Market Growth Rate (시장 성장률) — is the market expanding?
  • X-axis: Relative Market Share (상대적 시장점유율) — your share vs. the largest competitor
         Market Growth Rate (시장 성장률)

       Relative Market Share
         (상대적 시장점유율)

Note: The X-axis is inverted — HIGH share is on the LEFT, LOW share on the RIGHT. This is the original BCG convention.

Quadrant 1: Stars (스타) — High Growth, High Share

Stars are market leaders in fast-growing markets. They generate significant revenue but also require heavy investment to maintain their leading position as the market expands.

Characteristics:

  • Highest revenue growth potential
  • Cash-hungry — growth requires continuous investment (capex, marketing, R&D)
  • Near cash-neutral: high inflows offset by high reinvestment needs
  • Competitive battles are fiercest here

Strategy: Invest heavily (적극 투자)

  • Protect and grow market share at all costs
  • Fund from Cash Cow proceeds
  • Build scale advantages before growth slows
  • Stars that maintain share become tomorrow's Cash Cows
  • If you underinvest, Stars degrade into Question Marks

Key question: "Are we investing enough to maintain share as this market grows?"

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.
