Rollback Analysis & Checklist

Current Time: !date K8s Context: !kubectl config current-context

Analyze a deployment or change for rollback safety and generate a prioritized rollback checklist. Documents findings to Obsidian.

Input

• Target: deployment, commit SHA, release tag, or PR reference
• Context: what went wrong or why rollback is being considered
• Optional: urgency level (immediate vs planned)

Investigation Strategy

Launch parallel investigation tracks:

Track 1: Codebase Exploration (explore agent)

• Identify all changes included in the rollback scope
• Map database migrations in the change set
• Find feature flags introduced or modified
• Identify API contract changes
• Assess backward compatibility

Track 2: Code Analysis (inferred agent: go/frontend/postgres)

• Analyze migration reversibility
• Check for data transformations that may not be reversible
• Identify breaking changes in APIs or contracts
• Review feature flag dependencies

Track 3: External Research (librarian agent)

• Find rollback patterns for similar changes
• Check for known rollback issues with dependencies
• Research safe rollback strategies for the change type

Rollback Safety Assessment

Safe to Rollback

• Code-only changes (no DB migrations)
• Additive API changes
• Feature-flagged functionality
• UI/frontend changes

Requires Caution

• Database migrations (check reversibility)
• API breaking changes (check client compatibility)
• Configuration changes (check dependent services)
• Infrastructure changes (check state)

Potentially Dangerous

• Destructive migrations (DROP, DELETE, column removal)
• Data transformations (may lose data)
• Schema changes with live traffic
• Multi-service coordinated deployments

Output

Write to Obsidian via obsidian_append_content at: $OBSIDIAN_PATH/Rollbacks/YYYY-MM-DD-HHMM-target.md

Note: $OBSIDIAN_PATH must be a vault-relative path (e.g., Projects/myapp), set per-project via direnv. The obsidian_append_content tool expects paths relative to the vault root.

Document Structure

Use this template for the Obsidian document:

@~/.config/opencode/templates/rollback-analysis.md

Behavior

1. Parse target to identify rollback scope (commits, migrations, config)
2. Infer appropriate code agent from change types
3. Launch explore, librarian, and inferred code agent in parallel
4. Assess migration reversibility and data safety
5. Identify feature flags and configuration changes
6. Generate risk assessment with specific blockers
7. Create prioritized rollback checklist with actual commands
8. Write analysis to Obsidian via obsidian_append_content with auto-generated filename: YYYY-MM-DD-HHMM-target.md
