TAMING THE AGENT (+ LLM) = CORRECTNESS + EFFICIENCY

---

CONTEXT EFFICIENCY

• ☆ data format: JSON → YAML (nested) / CSV (flat) / TOON
• ☆ agent control over context: ex let agents write SQL queries
• ☆ good tool descriptions: smart yet succinct

---

NO TOOL SPRAWL

• ☆ default core toolset: ex logs, metrics, traces
• ☆ opt-in specialized toolset: ex synthetics

---

guide the agent

• ☆ specialized search docs tool: RAG / efficient docs access
• ☆ good error messages: Actionable
• ☆ good server-level instructions: ex "use search docs tool"
