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

micro-learning 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 8d 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

Micro-Learning

Design bite-sized learning experiences that fit into busy schedules.

What is Micro-Learning?

Feature Traditional Micro-Learning
Duration 30-60 min 2-10 min
Format Lecture, textbook Video, quiz, interactive
Focus Multiple topics Single concept or skill
Schedule Fixed time On-demand, just-in-time
Retention Variable High (spaced, focused)

Design Principles

1. One Concept Per Module

Each micro-learning unit should teach exactly one thing:

  • One formula or rule
  • One step in a process
  • One concept or definition
  • One tool or technique

2. Structure Each Module

Hook (15s) → Why this matters
Core (2-5 min) → The concept, demonstrated
Apply (1-2 min) → Quick practice or scenario
Check (30s) → One question to confirm understanding

3. Mobile-First Design

  • Vertical video (9:16 aspect ratio)
  • Large text, high contrast
  • Touch-friendly interactions (tap, swipe)
  • Offline-capable
  • Progress sync across devices

Engagement Patterns

  • Streaks: Daily login rewards (Duolingo model)
  • Push notifications: Reminders (not spam)
  • Leaderboards: Optional, opt-in competition
  • Badges: Complete a series → earn recognition
  • Social sharing: Post achievements

Delivery Strategy

  • New module every 1-3 days
  • Spaced review: previous module content appears 1, 3, 7 days later
  • Just-in-time: deliver module right before user needs it
  • Seasonal: align with calendar events or product launches

Platform Best Practices

  • Track completion rate (target >70%)
  • Track assessment score (target >80%)
  • A/B test module length, format, and schedule
  • Survey learners after each series for improvement
  • Iterate based on where learners drop off
Changes

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.
