Self-contained

The deck lives at /static/decks/mesocosm/ and is styled with the shared mesocosm design system (/static/design-system/). It works offline and embeds anywhere.

What’s inside

1. mesocosm — the platform in one line
2. Definitions — environment, state, observation, action space, episode (with a Wordle example)
3. The Environment Workflow — reset → observation → action → step → reward → repeat → close
4. The Agent Loop — Observe · Think · Act · Repeat (ReACT)
5. The Process — idea → public showcase
6. The Contract — the four endpoints (/health, /reset, /step, /close)
7. Local checklist — run the endpoints by hand
8. env.py — the game/task logic
9. adapter.py — the server
10. benchanything.json — the rulebook
11. The package — the files to build everything
12. We handle the rest — submit and bench
13. Automated grading — your env emits signal, scoring decides the verdict
14. Pass/fail vs scored — the two rubric flavors
15. Multi-criteria rubrics — combine criteria & guard the score
16. Demo — Intertwine — Don’t lose your contexts
17. Demo — KleoKlaw — a job board you run from your texts
18. Q&A / brainstorm
