Most likely because there is no active executable plan bar right now.
In Flux, Start is only available when a valid plan has actually been created for execution; the modification-tools guidance makes @plan the thing that generates that executable plan state, and it’s separate from just showing text that says “plan is ready” . If that plan was never created, expired, was replaced by later chat turns, or the current project/session is read-only, the button won’t be clickable.
In your case, one especially important clue is that your current context says User can edit project: false. If you don’t have edit access to this project, Flux may let you discuss plans but not actually execute them here.
Most likely reasons
  • You don’t have edit permission on this project
    • Your current context indicates read-only access, so execution can be blocked even if we’ve discussed a plan.
  • The plan bar is stale or no longer active
    • A newer message can invalidate the prior executable state, leaving only the text history.
  • The previous response was just a summary, not an active executable plan
    • Saying “click Start” in chat is not the same as a currently live plan object.
  • The project/page needs a refresh
    • Sometimes the UI state lags behind the conversation.
What to try
  • Refresh the project tab.
  • Check whether you are in your editable copy of the project, not a read-only/shared version.
  • Ask me to recreate the plan, then look for a fresh plan bar immediately under that response.
  • If this is someone else’s project, fork/clone it into your own editable workspace first.
Important note for this project
Since your context says you cannot edit this project, that is probably the main blocker. If you want, I can help you create a new editable copy prompt or a fork/clone link so you can run the work there.
