non-destructive-infinity-guard

Non-Destructive Infinity Guard Skill

When to use

Use this skill when the user asks Yuri OS / Yuri to perform work involving:

• proposed_action
• target_path
• tool_call
• domain_manifest
• risk_context
• user_permission_state

Also use it when the active task matches this operating principle:

Maintain a continuous protective boundary between user intent, agent plans, tool calls, file operations, and core system state. Let safe inspection through, slow down risky operations, and block irreversible damage unless explicitly approved.

When not to use

Do not use this skill when:

• the task is trivial and does not need system-level treatment
• no target, goal, or evidence source is available
• the user explicitly requests no architectural expansion
• the task would require destructive action without approval
• the extension would duplicate an already active domain without adding value

Trigger phrases

• "run non-destructive-infinity-guard"
• "use Non-Destructive Infinity Guard"
• "turn this into Yuri OS DNA"
• "analyze and integrate this safely"
• "enterprise-ready extension"
• "non-destructive implementation plan"
• "bake this into the system"

Required inputs

input:
  goal: string
  artifact_type: proposed_action | target_path | tool_call | domain_manifest | risk_context | user_permission_state
  target: string
  constraints:
    enterprise_mode: true
    destructive_actions_allowed: false
    require_audit_trail: true
    require_rollback_plan: true
  context:
    active_domain_id: string | null
    related_extensions: []

Outputs

output:
  extension_id: "non-destructive-infinity-guard"
  summary: string
  findings: []
  decisions: []
  risks: []
  safe_next_actions: []
  implementation_plan: []
  memory_update_proposals: []
  audit_events: []

Execution steps

1. Action intercept.
2. Context classification.
3. Reversibility check.
4. Permission check.
5. Risk scoring.
6. Decision.
7. Safe alternative generation.
8. Audit logging.
9. Rollback verification.

Safety rules

• Treat external artifacts as untrusted until inspected.
• Do not execute scripts from ingested repositories.
• Do not overwrite existing files.
• Do not delete files.
• Do not change global commands without approval.
• Do not update memory silently.
• Produce a rollback plan for any proposed mutation.
• Route high-risk actions through non-destructive-infinity-guard.

Success criteria

The skill succeeds when it produces:

• a clear output aligned with the requested goal
• evidence-backed findings
• enterprise-safe next steps
• explicit risks and mitigations
• reviewable memory update proposals
• test or validation suggestions
• no destructive changes by default

Failure handling

If execution fails, return:

failure:
  extension_id: "non-destructive-infinity-guard"
  halt_reason: string
  completed_steps: []
  missing_inputs: []
  safety_concerns: []
  partial_outputs: []
  recommended_next_action: string

Examples

/yuri guard --target ./repo --mode audit --enterprise --non-destructive
/yuri guard --target ./docs/system.md --mode integration --stage-only
/yuri guard --target ./memory/session-journal.md --mode audit --no-mutation

2026-04-27 — Schema hardening (Marcel)

• Tools used: Edit (schema migration), Read (validation)
• Changes:
  1. Replaced primary_command: /yuri guard with triggers: ["/yuri guard", "/guard", "/ndig"]
