plan-checklist: Claude checks a plan step off with evidence while a progress bar fills above the prompt

A Claude Code mod that turns the plan you approve in plan mode into a todo list, and lets Claude check a step off only when it shows how it verified it.

━━━━────────  1/3  Next  Fix the refund logic          [Show all]

Install

At the prompt of a Claude Code terminal session:

/plugin install plan-checklist --marketplace Jh-jaehyuk/plan-checklist

Answer y to add the marketplace, then pick a scope (user scope loads it in every session). It is active right away.

How it works

  1. Approve a plan. When you accept a plan in plan mode, its steps become a todo list. The steps are the plan's checkboxes; if there are none, its top-level numbered list; failing that, its top-level bullets.
  2. Watch progress above the prompt. A one-line band shows the progress bar and the step Claude is on. Press Show all to see every step, and Hide to collapse it again.
  3. Claude checks steps with evidence. Claude marks a step done through the plan_check tool, and must say which verification it ran and what came out (for example pytest tests/test_refund.py → 12 passed). A check without real evidence is refused.
  4. Nothing gets forgotten. Every turn, Claude is reminded of the remaining steps. The list survives /compact, and /clear wipes it.

When every step is checked you get a toast and the bar turns green.

Commands

CommandWhat it does
/checklistLists every step with the evidence Claude gave for it

Settings

OptionValuesDefault
languageen, koen

Change it from /config, or in settings.json:

{ "pluginConfigs": { "plan-checklist": { "options": { "language": "ko" } } } }

The language applies to the band, the toasts, /checklist and the reminder Claude reads.

Limits

  • The list lives in the session. Resuming the session in a new process (--resume) starts without it.
  • A plan without checkboxes, a numbered list or bullets has no steps to track; you get a toast saying so.
  • At most 20 steps are tracked.
