`/collaboration:pre-mortem`

Use when planning initiatives where early risk surfacing saves rework.

Inputs

Initiative and horizon (30/90/180 days)
Success definition
Known risks/compliance constraints

Steps

Define success state and horizon (default 90 days).
List top failure modes across tech, UX, org, market, compliance.
For each, propose mitigations/guardrails with Effort (S/M/L) and Owner.
Pull 2–3 mitigations that double as feature ideas.
Create Tasks for guardrails or pass to /ctx:plan.

Output Template

### Success State (horizon)
### Failure Modes
### Mitigations & Guardrails (effort, owner)
### Feature Candidates from Mitigations
### Immediate Tasks

Pairings

Run after /collaboration:concept-forge to sanity-check top concepts.
Feed guardrails into /dev:code-review or security skills as needed.
