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

aikido 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 7d 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.

Practice Aikido

Develop an aikido practice rooted in centering, blending with incoming force, and resolving conflict through controlled technique rather than opposing strength with strength.

When to Use

  • Learning a defensive martial art that prioritizes de-escalation and controlled resolution
  • Developing the ability to redirect aggression without causing unnecessary harm
  • Building safe falling skills (ukemi) applicable to any physical activity or emergency
  • Cultivating calm centeredness under physical pressure or confrontation
  • Complementing tai chi or meditation with a partner-based martial practice (see tai-chi, meditate)
  • Training awareness and response to multiple simultaneous threats

Inputs

  • Required: Practice space with a padded or yielding surface (tatami, judo mats, grass; avoid concrete)
  • Required: Comfortable clothing allowing full range of motion (gi preferred; loose exercise clothing acceptable)
  • Optional: Training partner (essential for techniques; solo practice covers centering, ukemi, and movement)
  • Optional: Practice weapons (wooden: jo staff ~128cm, bokken sword ~102cm, tanto knife ~30cm)
  • Optional: Experience level (beginner, intermediate, advanced; default: beginner)
  • Optional: Available practice time (minimum 20 minutes; recommended 60-90 minutes)

Procedure

Step 1: Ground and Center

Every aikido technique begins from a centered state. Without center, technique becomes muscular struggle.

  1. Stand in hanmi (half-facing stance): one foot forward, feet roughly shoulder-width apart at 60-degree angle
  2. Bend knees slightly — weight sinks toward the one-point (seika tanden), located 5cm below the navel
  3. Relax the shoulders completely — let them drop away from the ears
  4. Extend awareness outward while keeping attention anchored at the one-point
  5. Test your center: have a partner push gently on your chest
    • If you resist with upper body, you are not centered — relax and sink lower
    • If you maintain stability without effort, center is established
  6. Practice weight underside: imagine that the heavy part of each arm is the underside; let the upper surface feel light and buoyant
  7. Extend ki: project calm, positive energy forward through the fingertips — not tension, but focused intention

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.
