 "title": "Share one native build across agents on JS-only branches",
 "page_title": "How to share one native build across agents on JS-only branches with Simfleet",
 "summary": "Cache native builds by fingerprint so many agents reuse one build and environment switches skip native rebuilds.",
 "who": "A team lead or platform engineer whose coding agents run many JS-only branches and keep triggering slow native rebuilds.",
 "problem": "Every branch or environment switch can force a fresh native build, which wastes time and machine resources when only JavaScript changed.",
 "outcome": "Native inputs are fingerprinted with JavaScript excluded, so agents on JS-only branches share one build, and switching staging and production does not rebuild native code.",
 "steps": [
  "`bun add -d simfleet`",
  "Add `buildCacheProvider: { plugin: require.resolve(\"simfleet/build-cache\") }` under `experiments` in `app.config.js` (inferred from the README snippet).",
  "`simfleet native plan`",
  "`simfleet native ensure` (inferred, check the README)"
 ],
 "agent_prompt": "Using the simfleet repo (entropyconquers/simfleet), set up the Expo build cache in <path-to-app> and run `simfleet native plan` to inspect the fingerprint. Expected output: a plan that lists the native inputs and whether a cached build exists. Verify that changing only a JavaScript file leaves the native fingerprint unchanged.",
 "agents": [

 "difficulty": "Advanced",
 "time": "1 hour 30 minutes",
 "basis": "readme",
 "caveat": "Only `projectName`, `nativeAuth`, and `nativeShells` feed the native fingerprint, so native changes outside those settings may not be detected as expected.",
