Plan using Claude Opus 4.6. Spawns an Opus Plan subagent with "ultrathink" to maximize reasoning depth. Note: does NOT use the extended thinking API — effort is prompted, not configured via budget tokens. Use when the user invokes /opus-plan or asks for a high-quality plan, architecture review, or deep implementation strategy.

Identify the task to plan from <command-args> if provided, otherwise from the current conversation context (the most recent user request or problem description).
Launch an Agent with these parameters:
subagent_type: "Plan"model: "opus"Generate a timestamp via Bash: date +%Y%m%d-%H%M%S
Ensure the ./tmp directory exists: mkdir -p ./tmp
Write the full plan to ./tmp/claude-plan-<timestamp>.md using the Write tool. Report the path to the user.
Present the plan returned by the subagent to the user. Do not summarize or truncate it.

You are planning the implementation of: <task>
Context:
- <any relevant files, constraints, or background from the conversation>
Produce a thorough implementation plan:
- Read all relevant files before recommending changes
- Identify the key files and components involved
- List the steps in order, with specific file paths and line numbers where applicable
- Call out risks, trade-offs, and alternative approaches
- Note any open questions that need the user's input before proceeding
