Risk Review Skill
Purpose
Catch high-impact, destructive, or irreversible changes before they happen — ensuring they're flagged, explained, and explicitly approved rather than executed silently.
When to Use
Before deleting files, data, or database records/tables.
Before schema/migration changes.
Before changes to auth, permissions, roles, or access control.
Before changes to environment variables, deployment config, or build/release config.
Before broad changes affecting many files (architecture/restructure).
Whenever a task "feels" risky even if it doesn't fit a category above.
When Not to Use
Routine, additive, easily-reversible changes (new component, new non-destructive function, new optional field with default).
Required Inputs
The proposed change/action.
Its scope: how many files/areas/users/data it affects.
Whether it's reversible and how (e.g. can be undone with a revert vs. permanent data loss).
Assumptions
"Reversible" means a normal revert/rollback restores the prior state without data loss — not just "technically possible with effort."
When in doubt about risk level, treat it as higher risk.
Step-by-Step Workflow
Identify the action's category:
Data deletion or overwrite (files, DB records, user data).
Schema/migration change.
Auth/permissions/roles change.
Environment/deployment/config change.
Broad multi-file/architecture change.
Other irreversible or hard-to-reverse action.
Assess reversibility: can this be undone easily (revert commit, restore from a non-destructive change) or would undoing it require restoring lost data/state?
Assess blast radius: how many users/files/areas of the app does this affect if something goes wrong?
If high-impact and/or low-reversibility:
Do not proceed automatically.
Clearly explain what the action does, why it's needed, what could go wrong, and what approval is being requested for.
Wait for explicit approval before proceeding.
If low-impact and reversible: proceed, but still note the action briefly if it's the kind of thing someone would want to know about (e.g. "added a new optional field with a default value").
