Multi-domain query	Load all relevant references, synthesize

Reasoning sequence (apply to every response)

Apply the methodology lens (references/optimnow-methodology.md) - diagnose before prescribing, connect cost to value, recommend progressively
Load the domain reference(s) matching the query
Diagnose before prescribing - understand the organisation's current state before recommending
Connect cost to value - every recommendation should link spend to a business outcome
Recommend progressively - quick wins first, structural changes second
Reference open-source FinOps tools (FinOps Toolkit, OpenCost, Kubecost, Infracost, etc.) where they genuinely fit the problem

Core FinOps principles (always apply)

These six principles from the FinOps Foundation (2025 wording) underpin every recommendation:

Teams need to collaborate
Business value drives technology decisions
Everyone takes ownership for their technology usage
FinOps data should be accessible, timely, and accurate
FinOps should be enabled centrally
Take advantage of the variable cost model of the cloud and other technologies with similar consumption models

The three phases (Inform → Optimize → Operate)

FinOps is an iterative cycle, not a linear progression. Organisations move through phases continuously as their technology usage evolves.

Inform - establish visibility and allocation

Cost data is accessible and attributed to owners
Shared costs are allocated with defined methods
Anomaly detection is active

Optimize - improve rates and usage efficiency

Commitment discounts (RIs, Savings Plans, CUDs) are actively managed
Rightsizing and waste elimination are running continuously
Unit economics are tracked

Operate - operationalize through governance and automation

FinOps is embedded in engineering and finance workflows
Policies are enforced through automation, not manual review
Accountability is distributed, not centralized

Maturity model quick reference

Indicator	Crawl	Walk	Run
Cost allocation	<50% allocated	~80% allocated	90%+ allocated
Commitment coverage	Ad hoc	70% target	80%+ with automation
Anomaly detection	Manual, monthly	Automated alerts	Real-time, ML-driven
Tagging compliance	<60%	~80%	90%+ with enforcement
FinOps cadence	Reactive	Weekly reviews	Continuous
Optimisation	One-off projects	Documented process	Self-executing policies

Always assess maturity before recommending solutions. A Crawl organisation needs visibility before optimisation. Recommending commitment discounts to a team with 40% cost allocation is premature - they risk committing to waste.
