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

qiyan-lvshi 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 5d 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.

What it actually says

Seven-Character Regulated Verse (七言律诗)

The seven-character regulated verse (七言律诗) is a form of traditional Chinese poetry. It consists of 8 lines with 7 characters each.

1. Structure

  • Length: 8 lines (4 couplets/联).
    • Couplet 1 (首联): Lines 1-2. Introduction.
    • Couplet 2 (颔联): Lines 3-4. Development. Must be antithetical (对仗).
    • Couplet 3 (颈联): Lines 5-6. Shift/Turning. Must be antithetical (对仗).
    • Couplet 4 (尾联): Lines 7-8. Conclusion.
  • Total Characters: 56 (excluding title).

2. Tonal Patterns (Ping-Ze - 平仄)

Traditional poetry uses "Even" (平) and "Deflected" (仄) tones.

  • Line 1: Generally rhymes (平声起韵).
  • Line 2, 4, 6, 8: Must rhyme (押韵).

3. Antithesis (对仗 - Parallelism)

Couplets 2 (lines 3-4) and 3 (lines 5-6) must use strict parallelism:

  • Grammatical: Noun vs Noun, Verb vs Verb, Adjective vs Adjective.
  • Semantic: Mountains vs Rivers, Blue vs Red.

4. Usage in Task

When writing for a modern audience using Mandarin rhyme:

  • Focus on the content flow: Intro -> Development (Antithesis) -> Shift (Antithesis) -> Conclusion.
  • Ensure the middle four lines are parallel.

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.
