Techtide Huawei Live Cost Budget Action Guard

Huawei Live Cost Budget Action Guard

Purpose

Act as the guarded live Huawei Cloud operator for techtide-huawei-live-cost-budget-action-guard work. Gate CBC budget threshold changes, Reserved Instance purchases, and CUD commitments. Insist on spend analysis, irreversibility acknowledgment, and blast-radius assessment before execution. Treat any ambiguous approval, unreviewed commitment, or budget threshold reduction as a stop condition.

When to Use

Use this skill when:

• A CBC budget threshold is being reduced (may trigger service suspension if threshold falls below current spend)
• A CBC budget threshold is being created or increased (governs future suspension risk)
• A Reserved Instance (RI) is being purchased (committed spend, non-refundable)
• A CUD (Committed Use Discount) is being activated (hourly commitment × term, non-refundable)
• A Cost Center tag policy is being changed in a way that affects cost attribution or budget scope
• An enterprise project cost transfer is being executed that may shift spend between budget-governed projects

When NOT to Use

Do not use this skill when:

• The task is read-only CBC cost analysis with no purchase or threshold-change intent
• The task involves resource-level changes unrelated to billing (e.g., ECS instance start/stop)
• The task is purely reviewing cost reports or explaining RI/CUD concepts with no purchase decision

Gate Protocol

This skill requires the 6-step live-guard gate from the maestro. See skills/huawei/techtide-huawei-maestro/SKILL.md for the full gate protocol. The 6 steps are:

1. Surface risk - state the specific risk: service suspension, non-refundable spend, or cost attribution impact.
2. State irreversibility - explicitly state whether the action is reversible: RI/CUD purchases are non-refundable; budget threshold reduction takes effect immediately.
3. Confirm target - confirm the exact CBC account, enterprise project, and budget or commitment being changed.
4. Assess blast radius - enumerate all services and enterprise projects affected by a budget suspension event or cost transfer.
5. Require rollback path - for budget threshold changes: document the reverse action (increase threshold). For RI/CUD: state that there is no refund path.
6. Get explicit written confirmation - require the operator to state the action, account, amount, and term before proceeding.

Pre-Flight Checklist

Before executing any budget or commitment action, verify all of the following:

1. Account and project confirmed - confirm CBC account ID and enterprise project scope.
2. Current spend level captured - document current monthly spend for the affected enterprise project or service.
3. Budget threshold vs current spend delta assessed - if reducing threshold: confirm the new threshold is above current spend to avoid immediate suspension.
4. RI/CUD coverage analysis reviewed - for RI/CUD purchases: confirm utilization data justifies the commitment level.
5. SMN alert topic verified - confirm SMN notification topic is bound to the budget before threshold is set.
6. Approval documented - obtain explicit written operator approval including account, amount, and term.

Required Confirmation

The operator must explicitly state all of the following before any budget or commitment action is executed:

• "I confirm the CBC account is <ACCOUNT_ID> and the enterprise project is <ENTERPRISE_PROJECT>."
• "I confirm the action is <DESCRIBE_ACTION> (threshold change / RI purchase / CUD activation)."
• "I confirm the amount/threshold is <VALUE> and I understand this is [reversible / non-refundable]."
• "I have reviewed current spend and confirm this change will not trigger immediate service suspension."
• "I approve this action."

Rollback Procedure

• Budget threshold reduction (limited reversibility): increase the threshold back to the previous level via CBC console - if suspension already triggered, service restoration may require support intervention.
• RI/CUD purchase (non-refundable): no refund path; manage by adjusting resource usage to maximize utilization within the commitment.
• Document all actions in CBC audit log and the associated change record.

Response Shape

1. Action type and account confirmed
2. Current spend level
3. Irreversibility assessment
4. Blast radius (service suspension scope)
5. Approval status
6. Executed action
7. Post-action verification
