 "title": "Explore an unfamiliar codebase without risking edits",
 "page_title": "How to explore an unfamiliar codebase without risking edits with Opencode",
 "summary": "Use the read-only plan agent to map a new repo and plan changes before touching any files.",
 "who": "A developer who just joined a project or inherited a repo and needs to understand it before changing anything.",
 "problem": "Pointing a coding agent at unknown code is risky when it can edit files or run commands right away.",
 "outcome": "A written summary of how the codebase is structured and a short change plan, with no files edited.",
 "steps": [
  "Run `npm i -g @opencode/cli@latest` (or use `brew install anomalyco/tap/opencode-v2` on macOS and Linux).",
  "Change into the project folder and start OpenCode with `opencode`. (inferred, check the README)",
  "Press the `Tab` key until the plan agent is selected.",
  "Ask it to map the main modules, entry points, and how the tests are run.",
  "Ask for a step-by-step plan for your change and review it before switching to the build agent."
 ],
 "agent_prompt": "Using the OpenCode repo at anomalyco/opencode, start the plan agent in <project-path> and ask it to summarize the code structure and list the files that would need changes for <task>. Expected output: a structured summary plus a numbered change plan. Verify that no files were edited, since the plan agent denies file edits by default.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README names the plan and build agents but does not say which models or providers they use, so check Opencode.ai/docs before relying on a specific setup.",

 "tags": [
  "Software and DevOps"
 ],
 "lang": "typescript",
 "requirements": [
  "A terminal on macOS, Linux, or Windows, or the desktop app installer for your platform",
  "One package manager available: npm, bun, pnpm, yarn, or brew",
  "A local project folder you want the agent to work in",
  "Configuration for OpenCode as described in the docs at opencode.ai/docs (the README only links to them)"
