@ifi/pi-plan

Planning mode extension for pi.

Built on top of the planning workflow from sids/pi-extensions/plan-md and adapted for oh-pi.

Installation

pi install npm:@ifi/pi-plan

Or install it as part of the full oh-pi bundle:

npx @ifi/oh-pi

Or use the package installer directly:

npx @ifi/pi-plan
npx @ifi/pi-plan --local

To remove:

npx @ifi/pi-plan --remove

What it does

• /plan starts planning when inactive and opens plan-mode actions when already active.
• Alt+P runs the same plan-mode toggle flow as /plan without sending /plan as chat text.
• Start location picker (shown when the session has branchable history):
  • Empty branch
  • Current branch
• If a session plan already exists with content, startup offers:
  • Continue planning
  • Empty branch / Current branch when branchable history is available
  • Start fresh when no branchable history is available
• /plan accepts an optional location argument:
  • file path → use that exact file as the plan file
  • directory path → create <timestamp>-<sessionId>.plan.md in that directory
• Shows a persistent banner while active with the active plan file path.
• Running /plan while active shows:
  • Exit
  • Exit & summarize branch
• Running /plan <location> while active moves the current plan file to the resolved location.
• Exiting plan mode prefills the editor only when the active plan file has content.
• After exit, a Plan mode ended. message is shown with the plan file and an expandable plan preview when available.

Commands

• /plan [location]

Tools in plan mode

Plan mode adds planning-specific tools only while active:

• task_agents — run isolated research tasks using the bundled subagent runtime (concurrency: 1-4)
• steer_task_agent — rerun one task from a previous task_agents run with extra guidance
• request_user_input — ask clarifying questions with optional choices and optional freeform answers
• set_plan — overwrite the active plan file with the complete latest plan text

When plan mode ends, these tools are removed again.

Notes

• By default, plan mode uses one plan file per session in the same directory as the session file, replacing the session extension with .plan.md.
• /plan [location] can override the plan file path.
• Plan files are kept after exiting so planning can be resumed later.
• The default plan-mode prompt is stored in packages/plan/prompts/PLAN.prompt.md.
• You can override that prompt globally by creating ~/.pi/agent/PLAN.prompt.md.
• If the override file is missing or blank, the bundled prompt is used.
