 "title": "Test an embedded agent offline with no API key",
 "page_title": "How to test an embedded agent offline with no API key with Pi Rust",
 "summary": "Run the minimal example against the deterministic faux provider to test agent behavior.",
 "who": "A Rust developer building an agent into their own app who needs repeatable tests that never touch the network.",
 "problem": "Agent tests that call a live model are slow, flaky, and cost money to run.",
 "outcome": "The agent loop runs end to end with fixed output and no credentials, so tests pass the same way on every run.",
 "steps": [
  "Run `git clone https://github.com/bigfish1913/pi-rust.git`",
  "Change into the folder with `cd pi-rust`",
  "Run `cargo run -p minimal`",
  "Read examples/minimal/src/main.rs and reuse its AgentBuilder setup in your own test"
 ],
 "agent_prompt": "Clone bigfish1913/pi-rust, run `cargo run -p minimal`, and then write a Rust test in <target-crate> that builds an agent with the faux provider and asserts the reply. Expected output: the minimal example prints 2 messages after run and the assistant reply. Verify that the test passes with no network access and no API key set.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The faux provider covers the paths your test scripts, so live provider behavior still needs its own checks against the real HTTP providers behind the providers feature flag.",

 "lang": "rust",
 "requirements": [
  "Rust 1.78 or later, for installing from crates.io",
  "An ANTHROPIC_API_KEY or OPENAI_API_KEY, or a ~/.rpi/agent/models.json file, for live model calls",
