Code was never the hard part.
Engineering is.

// Step 1: Research — Gemini Flash, read-only, cheap — runs freely
const research = await agent("Analyze the codebase for related patterns", {
  tools: ["glob", "grep", "read"],   // read-only — can’t accidentally change anything
  model: "gemini-flash",             // cheap and fast; near-100% on structured lookups
  provider: "google"
});

// Step 2: Plan — Sonnet for reasoning — balanced accuracy and cost
const plan = await agent("Propose a fix based on this research: " + research);
const approved = await prompt("ApprovalForm", {  // human checkpoint — resets the probability clock
  title: "Review the proposed plan",
  plan: plan,
  options: ["Approve", "Approve with changes", "Reject"]
});

// Step 3: Execute — only what the engineer approved
await agent("Implement the approved plan: " + approved);

// Step 4: Validate — always runs — the architect said validation is non-negotiable
await bash("npm run test");
const review = await agent("Review the diff for regressions");

// Step 5: Commit — your call — always
await prompt("ResultsView", {
  title: "Review changes before committing",
  diff: review,
  actions: ["Commit", "Request changes", "Discard"]
});
