I make agent skills, developer tools and browser games. The ones I like best refuse to guess: a claim has to name the file it came from, observations are sealed before any reasoning starts, and every number is run before it goes on the page.

Finds where a photo was taken, and shows its work. No text, no plates, no landmarks: one bridge and one mountain put the camera within 2 m. npx skills add Oldcircle/geo-sleuth |
Reads a photo the way Sherlock Holmes reads a stranger. Observations are sealed before any deduction; on a real desk photo the owner graded 5 hits, 1 miss, 0 made-up observations. npx skills add Oldcircle/holmes-skill |
Both are plain Agent Skills and work in Claude Code, Codex, Cursor, Gemini CLI, OpenCode and GitHub Copilot.
| Project | What it does |
|---|---|
| 🪴 Trellis | The discipline layer for file-based agent memory: budgets, ownership rules, and a linter that keeps CLAUDE.md and MEMORY.md from rotting. |
| 🎓 deep‑lecture | A teaching method as a Claude Code skill: read the primary sources, run every number, publish one interactive page, patch it wherever the learner gets lost. In Chinese. |
| 🪟 wsl‑agent‑kit | One double-click on Windows sets up WSL2, your pick of nine AI agents and a Chinese office workspace. In Chinese. |
| ⚡ ai‑shell | Build your own Claude Code from scratch: streaming query loop, tools, permissions, context compaction. |
| 🔬 trace‑viewer | Every LLM call, tool call and token spent in an OpenClaw agent run, laid out step by step. |

RouterKGQA: Specialized–General Model Routing for Constraint-Aware Knowledge Graph Question Answering A small specialized model drafts the reasoning path over the knowledge graph. A large general model is called in only when that path cannot be reached: +3.57 F1 over the previous best, at 1.15 LLM calls per question. |
 backprop-viz A 3D walkthrough of a GPT's backward pass, built on llm-viz. Every block holds its gradient, computed live. |
 Anima Seven anime characters, each its own LLM agent, in one seaside town. Friendships and grudges come out of the interactions. |
 BlockFire 方块火线 · play ↗ Minecraft meets first-person shooter, in one HTML file. Dig, build walls, hold off the waves. |
Also: Stardew Anima, an MCP server with 28 intent-level tools that let an LLM play Stardew Valley without screenshots.
