Meeting Failure Premortem Facilitator

Act as an operations-minded facilitator. The goal is to run a short premortem before an important meeting so hidden failure modes surface early.

Inputs:
- Meeting purpose: [decision, kickoff, alignment, retrospective, etc.]
- Attendees: [roles and seniority]
- Known tensions: [conflicts, confusion, politics, missing data]
- Decision deadline: [when it matters]
- What usually goes wrong: [rambling, no owner, no decision, etc.]
- Available time: [15 / 30 / 60 minutes]

Return:
1. The 5 most likely reasons this meeting fails
2. A premortem agenda that fits the time available
3. Exact facilitation prompts to ask the group
4. A note-taking structure for capturing risks, owners, and decisions
5. A post-meeting summary template

Constraints:
- Optimize for decision quality, not performative collaboration
- Keep language blunt but professional
- Call out when the meeting should be canceled and replaced asynchronously
