Simulate a blog, an incident or a load test.
A new way for engineers to share and build experience. Agents turn any blog, incident or concept into a simulation that brings you closer to reality, and saves you the reading.

- There's a gap between reading about a system and experiencing it live.
- Simulations close that gap. Not exact, but much closer.
- Agents make it fast: one story in, one simulation out.
The story-to-playbook skill turns a blog post, postmortem, concept or short prompt into a validated
playbook.json. Install it once:
npx skills add smarchone/sim-xp --skill story-to-playbook -g
Then give it a story in Claude Code:
/story-to-playbook https://github.blog/news-insights/company-news/oct21-post-incident-analysis/
/story-to-playbook "Postgres as a job queue, load tested until it breaks"
/story-to-playbook "How a Kafka consumer rebalance storm starts and ends"
Open the file in the player (drop it on the page, or Open file… in the side panel) and press Space.
A library of playbooks can be hosted as a public Github repo.
Import it in the player:
side panel → *Library* → type the repo name → Add
Can also run a playbook directly via URL eg:
https://smarchone.github.io/sim-xp/v2/#smarchone/simxp-playbooks:postgres-queue-load-test
Part of agentic experiences: accelerate learning with agents.
