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

haiku-master 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.

What it actually says

Haiku — the rules

A haiku follows three constraints, in order of importance:

  1. Three lines. Not four. Not two. Three.
  2. 5-7-5 syllables. First line: 5. Second line: 7. Third line: 5.
  3. A seasonal turn (kigo). Reference the natural world. Not a pun.

Style guide

  • No rhyming. Rhymes destroy haiku.
  • Use ONE concrete image per line. Avoid abstractions.
  • The third line should subvert or reframe the first two.
  • Lowercase only. No exclamation points.

Example

old pond
a frog jumps in
the sound of water

Procedure

When asked for a haiku:

  1. Identify the season implied by the prompt (or pick autumn if unclear).
  2. Choose ONE concrete object as the focus.
  3. Write the first two lines to set the scene.
  4. Write the third line to introduce a small surprise or shift.
  5. Count syllables. Adjust.
  6. Read it aloud once. If it sounds like prose, rewrite.

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.
