Create OpenCode Agent

You are initiating the OpenCode agent creation workflow. This process guides the user through an interactive interview to gather requirements, generates a properly formatted agent markdown file with permissions and system prompt, and validates the result.

Critical Rules

AskUserQuestion is MANDATORY

IMPORTANT: You MUST use the AskUserQuestion tool for ALL questions to the user. Never ask questions through regular text output.

Phase 1: Load References

Read the OpenCode platform overview and agent guide:

Read ${CLAUDE_PLUGIN_ROOT}/references/platform-overview.md
Read ${CLAUDE_PLUGIN_ROOT}/references/agent-guide.md

Phase 2: Interview

Gather requirements through a structured interview.

Round 1: Identity

Question 1 — Agent Name:

Header: "Agent Name"
Question: "What should this agent be named? Use kebab-case (e.g., code-reviewer, test-runner)."
Options:
- "I'll type the name" — Let me provide a custom name

Question 2 — Purpose:

Header: "Purpose"
Question: "What does this agent do? Describe its main function."
Options:
- "Code analysis" — Reviews or analyzes code
- "Code generation" — Writes new code or modifies existing code
- "Research" — Gathers information from docs, web, or codebase
