🏋️ Challenges — Module 01 (Fundamentals)

1. Installation: install OpenCode V2 using two different methods and confirm opencode --help works with both.
2. TUI: in a session, use @ to attach a file with a line range and ask a question about that snippet.
3. Config: create an opencode.jsonc with $schema, a model and an ask permission for git push *.
4. CLI settings: change the theme and a keybind in cli.json and confirm they only apply to the terminal (not the server).
5. Models: connect a provider and run the same prompt with the #low and #high variants, comparing latency.

💡 Solution (challenge 3)

{
  "$schema": "https://opencode.ai/config.json",
  "model": "anthropic/claude-sonnet-4-5",
  "permissions": [
    { "action": "shell", "resource": "git push *", "effect": "ask" }
  ]
}

💡 Solution (challenge 5)

opencode run --model anthropic/claude-sonnet-4-5#low  "Explain this repository"
opencode run --model anthropic/claude-sonnet-4-5#high "Explain this repository"

Compare time and depth. Variants come from the model's catalog.
