Update OpenCode Command

You are initiating the OpenCode command update workflow. This process locates an existing command, researches current platform best practices, analyzes the command for issues, 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 command guide:

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

---

Phase 2: Locate Command

Find the command to update.

If $ARGUMENTS is provided:

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

If no arguments:

1. Search for OpenCode commands in the workspace:
   • Glob for .opencode/commands/*.md
   • Glob for ~/.config/opencode/commands/*.md
2. Present found commands using AskUserQuestion:
   • Header: "Select Command"
   • Question: "Which command would you like to update?"
   • Options: List found commands (up to 4; include "Other" for custom path)

Read the selected command 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 command format compatibility.

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

    Specific questions:
    1. Are there any new command frontmatter fields?
    2. Has the $VARIABLE system changed?
    3. Are there new command discovery paths?
    4. Any changes to the model override behavior?

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

---

Phase 4: Analyze

Compare the existing command against current best practices:

Frontmatter Issues

Issue	Detection	Fix
Wrong model format	Must be provider/model-id if present	Convert format
Skill-only frontmatter	Fields like user-invocable, name, allowed-tools	Remove
Missing description	Should have for command listing	Add
Unknown agent value	If agent field present, agent must exist	Verify or remove
subtask type	Must be boolean if present	Fix type

Body Issues

Issue	Detection	Fix
Inconsistent $VARIABLEs	Mixed case or invalid patterns	Standardize to uppercase
Claude Code tool names	AskUserQuestion instead of question	Convert
mcp__ format	Double-underscore MCP naming	Convert to single-underscore
Hardcoded paths	System-specific absolute paths	Convert to relative, $VARIABLE, or @filepath reference
Very long body	Commands should be concise workflow shortcuts	Suggest splitting into a skill
Missing shell injection	Could use !`command` for dynamic context	Suggest where appropriate

Structure Issues

Issue	Detection	Fix
No clear steps	Unstructured instructions	Add numbered steps
Missing output specification	No description of expected output	Add output section
Unused variables	$VARIABLEs declared but never used in body	Remove or use

---

Phase 5: Present Findings

Present the analysis:

## Update Analysis: {command-name}

### Errors (must fix)
{list}

### Warnings (should fix)
{list}

### Suggestions
{list}

### Research Notes
{findings}

Use AskUserQuestion for approval:

• Header: "Apply Updates"
• Question: "Would you like to apply these updates?"
• Options:
  • "Apply all"
  • "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 command file
2. Fix frontmatter first, then body content
3. Preserve the command's intent

---

Phase 7: Validate

Spawn the validator agent:

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

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

Present validation results and a before/after summary.

CRITICAL: Complete ALL 7 phases before finishing.
