A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 16 wraps capabilities into standalone plugins: drop a subdirectory with a plugin.ts into plugins/ and the main program loads it automatically at startup — commands, tools, and HTTP services all become plug-and-play.
A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 15 integrates MCP: servers are declared in a config file, JSON-RPC runs over stdio at startup, and tools provided by external processes land straight in the model's tool list.
A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 14 reuses Day 13's chunking and BM25 search to build a lightweight knowledge base that collects web pages and files and returns the relevant passages for a question.
A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 13 cuts long-term memory into small chunks, finds the relevant ones with BM25, and automatically places them into the context before every turn.
A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 12 adds `search` and `fetch`: one searches the repository by content, the other reads a web page and converts it to plain text.
A 7-day tutorial on building an Agent from scratch, writing the simplest possible Agent/Harness in TypeScript. Day 11 packages task instructions and tools into skills that can be loaded and unloaded on demand, controlling which tools the model can see at any moment.
