Oc update agent

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 This process locates an existing agent, researches current platform best practices, analyzes the agent for outdated patterns, and applies updates with validation.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
2. 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

Issue	Detection	Fix
name field present	Should not exist — name from filename	Remove
skills field present	Skills not assignable to agents	Remove
Invalid mode value	Must be primary, subagent, or all (default: all)	Fix or default to all
Wrong model format	Must be provider/model-id	Convert
Temperature out of range	Must be 0.0-1.0	Clamp to valid range
top_p out of range	Must be 0.0-1.0 if present	Clamp to valid range
Invalid permission syntax	Values must be allow/ask/deny/true/false	Fix syntax
Missing description	Required field	Add based on agent content

Body Issues

Issue	Detection	Fix
Subagent uses question	Subagents can't use question tool	Add note or restructure
Claude Code tool names	AskUserQuestion instead of question	Convert to OpenCode names
mcp__ format	Double-underscore MCP naming	Convert to single-underscore
${CLAUDE_PLUGIN_ROOT} refs	Claude Code path variable	Remove or convert
Missing purpose statement	No clear first sentence	Add purpose statement
No output format section	Agent should specify output	Add output format

Permission Issues

Issue	Detection	Fix
Glob pattern syntax errors	Invalid patterns in permission rules	Fix syntax
Overly permissive subagent	Subagent with full write/bash access	Suggest tightening
Missing common tools	No read/glob/grep permissions set	Add basic permissions

---

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.
