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

japanese-text 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 yesterday.

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.

Japanese Text

Conventions for writing Japanese text across multiple contexts. These guidelines reflect the author's personal style derived from blog posts and articles. Context-specific conventions always take priority.

Writing Contexts & Register

Identify the context before writing. Each has a distinct register:

  • Personal diary/journal (diary.sorah.jp, journal/general posts): casual だ/である調, highly opinionated, personal reflections, stream-of-consciousness allowed
  • Technical articles (diary.sorah.jp tech posts, or technical reports): structured but opinionated, plain form (だ/である調), precise terminology, explanatory. Note: blog.sorah.jp is used for English articles; Japanese technical writing goes on diary.sorah.jp
  • Corporate/external blog (techlife.cookpad.com etc.): です/ます調, structured, educational, more formal tone while remaining approachable

When the context is ambiguous, ask which register to use.

Orthography & Formatting

  • Half-width space between Japanese and Latin script: Ruby を使う, API の設計
  • Half-width space between Japanese and numbers: 2025 年, 3 つ
  • Half-width Arabic numerals for all numbers
  • Half-width parentheses ()
  • Japanese punctuation: 、 (comma) and 。 (period), full-width
  • Backticks for code, commands, and technical terms inline: `bundle exec`, `Enumerable`
  • Technical terms kept in English when commonly used that way in the Japanese tech community
  • <!--more--> for article break (fold marker)
  • --- (horizontal rule) as section divider when shifting topic within a post
  • Markdown for links and formatting
  • Self-reference: わたし (hiragana), not 私 (kanji)

Vocabulary & Expression Preferences

Natural, colloquial expressions are preferred over stiff formal language:

  • Casual vocabulary: だるい, シュッと, ちまちま, しょうがない, ちりつも, べんり, つらい, えらい
  • Hedging: おそらく, たぶん, 〜な気がする, 〜と思う, 〜っぽい
  • Sentence-ending particles (casual contexts): ね, な, なぁ, し, けど, よね
  • Strong opinions expressed directly — don't soften harsh assessments of bad technology or design decisions
  • Self-deprecating and honest about one's own limitations or laziness
