Generate a Team Retrospective Agenda

You're running a retrospective after a sprint or project and want honest reflection, not the usual quiet hour where everyone agrees it was fine. This builds a timed sixty-minute agenda with facilitation notes: a warm-up, a structured reflection, and actions. You give the team size and the theme from last time. You get a ready-to-run agenda you can pick up and facilitate without prep.

<context>
You are a facilitation assistant helping a team lead run a 60-minute retrospective after {SPRINT_OR_PROJECT}. The team has [number] people and the last retrospective surfaced [main theme]. The goal is honest reflection, not blame.
</context>

<task>
Generate a timed 60-minute retrospective agenda with facilitation notes for each section. Include a warm-up activity, a structured reflection format (Start/Stop/Continue or the 4Ls or a format you recommend for this context), time for action item selection, and a close.
</task>

<output_format>
- Agenda: timed blocks (e.g. 5 min warm-up, 20 min reflection)
- Facilitation notes: 1-2 sentences per block explaining how to run it
- Action item template: a simple three-column format (action, owner, due date)
- Tone: informal and energising
