Update OpenCode Agent

You are initiating the OpenCode agent update workflow. This process locates an existing agent, researches current platform best practices, analyzes the agent for outdated patterns, and applies updates with validation.

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:

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

Phase 2: Locate Agent

Find the agent to update.

If $ARGUMENTS is provided:

1. Check if the argument is a file path — read it directly
2. If it's an agent name — search for {name}.md in known directories

If no arguments:

1. Search for OpenCode agents in the workspace:

• Glob for .opencode/agents/*.md
• Glob for ~/.config/opencode/agents/*.md

1. Present found agents using AskUserQuestion:

• Header: "Select Agent"
• Question: "Which agent would you like to update?"
• Options: List found agents (up to 4; include "Other" for custom path)

Read the selected agent file and store its contents.

Phase 3: Research

Spawn the researcher agent to check latest documentation:

Task:
  subagent_type: "agent-alchemy-opencode-tools:oc-researcher"
  prompt: |
    Research the latest OpenCode documentation for agent format compatibility.

    Artifact type: agent
    Current artifact content:
    ---
    {contents of the agent file}
    ---

    Specific questions:
    1. Are there any new agent frontmatter fields?
    2. Have permission syntax rules changed?
    3. Are there new agent modes or capabilities?
    4. Any changes to subagent behavior or limitations?

    Reference guide: ${CLAUDE_PLUGIN_ROOT}/references/agent-guide.md

Phase 4: Analyze

Compare the existing agent against current best practices:

Frontmatter Issues

Body Issues

Permission Issues

Phase 5: Present Findings

Present the analysis organized by severity:

## Update Analysis: {agent-name}

### Errors (must fix)
{list with explanations}

### Warnings (should fix)
{list with explanations}

### Suggestions
{list with explanations}

### Research Notes
{findings from researcher agent}

Use AskUserQuestion for approval:

• Header: "Apply Updates"
• Question: "Would you like to apply these updates?"
• Options:
• "Apply all" — Fix everything
• "Errors and warnings only"
• "Errors only"
• "Cancel"
• multiSelect: false

Phase 6: Apply Updates

Apply changes based on user selection:

1. Use Edit to modify the agent file
2. Fix frontmatter first, then body content
3. Preserve the agent's intent and system prompt personality

Phase 7: Validate

Spawn the validator agent:

Task:
  subagent_type: "agent-alchemy-opencode-tools:oc-validator"
  prompt: |
    Validate the following OpenCode artifact:

    Type: agent
    Path: {path to updated file}
    Reference guide: ${CLAUDE_PLUGIN_ROOT}/references/agent-guide.md

Present validation results and a before/after summary of changes.

CRITICAL: Complete ALL 7 phases before finishing.
