[agent\_craft] Agent accuracy drops as more tool definitions crowd the system prompt

Keep fewer than about 20 tools available per turn; defer rarely used tools with tool search or namespace loading.

Journey Context:
Each tool definition consumes tokens and competes for attention. The common mistake is exposing the entire tool surface on every turn. OpenAI's function-calling guidance notes that accuracy suffers with many functions and recommends tool search or namespaces to load tools only when relevant. Treat tool availability as a context-budget decision, not just a capability list.
