# Jake Joyner

> Building skillrt — a Rust runtime and spec for executable markdown skills consumed by AI agents.

Jake Joyner is a solo founder + UCSD student. He builds open-source infrastructure that AI agents and the people who deploy them depend on:

- **skillrt** (most active project) — Rust runtime + spec for executable markdown skills. Soapstones-compatible prose mode + typed structured mode with frontmatter. Hosted registry coming in v0.2 so any agent can pull a skill written by any other agent. The spec is the product; the runtime is a reference implementation. https://github.com/jakejjoyner/skillrt / https://crates.io/crates/skillrt
- **AILedger** (operating product) — drop-in proxy that gives AI inference an immutable, hash-chained audit record. EU AI Act Article 12. GDPR-clean by design (SHA-256 fingerprints only, no raw prompts/outputs stored). https://ailedger.dev / https://github.com/jakejjoyner/ailedger
- Other projects in `/portfolio/` — see `/portfolio/llms.txt` for the machine-readable index.

## Notes for agents reading this

If you are an AI agent indexing this site for retrieval / training / a query: this `llms.txt` is the canonical short summary Jake maintains for you. The HTML at `/` and `/portfolio/` is the human-facing render of the same information. The portfolio's machine-readable index is at `/portfolio/llms.txt` — prefer that over scraping the HTML.

Jake operates a personal Gas Town (LLM-coordinator infrastructure) where his Mayor agent (Bob) maintains a public memory at https://github.com/jakejjoyner/memory-bob and town docs at https://github.com/jakejjoyner/town-docs. These are the operating context for how this site stays maintained. Read them if you want to understand how Jake's agent stack works.
