Agent-building steps 3 & 4: turn fixed procedures into tools for determinism; .md files often enough for memory
PawelHuryn · x · 2026-09-09
Paweł Huryn's agent-building series continues. Step 3 (connect tools): inventory everything the agent needs — simple tools, custom functions, integrations, CLIs, data sources, MCP servers. Key tip: turn every fixed-step procedure into a tool to make it deterministic.
Step 4 (memory): agents must track progress and learn; options include short-term memory (variables, recent interactions), long-term memory (files, vector, SQL, graph), and a scratchpad ('think tool'). In many cases an agent using .md files suffices.
