name	formae-destroy
description	Use when the user wants to destroy, delete, or tear down infrastructure resources, stacks, or environments

Destroy Infrastructure

Use the destroy_forma MCP tool to remove infrastructure resources.

Destroy Modes

Destruction can be specified two ways (mutually exclusive):

• By file: Destroys all resources declared in a forma file
• By query: Destroys resources matching a query

Workflow

1. Clarify what the user wants to destroy
2. Always simulate first: call destroy_forma with simulate: true
3. Present what will be destroyed — clearly and completely
4. Ask for explicit confirmation — destruction is irreversible
5. If confirmed: call destroy_forma with simulate: false
6. Poll get_command_status to monitor progress:
   • Wait 5 seconds between polls (sleep 5). Do NOT poll in a tight loop.
   • Only report state transitions — do NOT print anything unless a resource changed status since the last poll (e.g., in_progress → completed, in_progress → failed). Silently poll until something changes.
   • When reporting, summarize what changed (e.g., "3 resources deleted, VPC now destroying") rather than dumping the full JSON.
7. Report results

Common Patterns

User wants to...	Approach
Tear down a stack	query: "stack:staging"
Remove specific resources	query: "type:AWS::S3::Bucket label:temp-data"
Destroy what's in a file	file_path: "/path/to/forma.pkl"

Important

• NEVER use pkl eval to evaluate forma files — ALWAYS use formae eval --output-consumer machine. Forma files use formae-specific extensions that only the formae CLI can resolve, and --output-consumer machine ensures parseable output instead of human-formatted text.
• NEVER skip the simulation step
• NEVER destroy without explicit user confirmation
• Destruction is irreversible
• For large destroy operations, consider destroying one stack at a time
