cloud-infrastructure

viktorbezdek/skillstack

Cloud infrastructure design and infrastructure-as-code (IaC) authoring. Use for Terraform module authoring, AWS CDK constructs, cloud architecture design (VPCs, load balancers, managed services, serverless), multi-region and disaster-recovery patterns, cost-optimisation analysis, and IaC code review. Trigger phrases: "write Terraform for", "design the AWS architecture", "set up a VPC", "convert this to CDK", "optimise our cloud costs". NOT for application-layer code — this skill models infrastructure, not the code running on it. NOT for Kubernetes application manifests (Deployments, Services, Ingress) — those belong in a k8s-specific skill. NOT for CI/CD pipeline configuration — that is a deployment concern separate from infrastructure provisioning.

competitive-intelligence

viktorbezdek/skillstack

Competitive intelligence and market positioning analysis for product and GTM decisions. Use for competitor landscape mapping, positioning gap identification, win/loss pattern synthesis, battlecard creation, market-sizing estimates (TAM/SAM/SOM), and differentiation analysis. Trigger phrases: "map the competitive landscape", "create a battlecard for", "analyse our win/loss patterns", "how do we differentiate from", "size this market". NOT for primary market research (customer interviews, surveys) — this skill works from existing public and internal data. NOT for financial modelling or investor decks — competitive context informs the story but this skill does not build financial projections. NOT for pricing strategy deep-dives — pricing has its own set of constraints and frameworks beyond competitive positioning.

2026-06-0510

database-design

viktorbezdek/skillstack

Database design and schema engineering for relational databases. Use for SQL schema design, ORM model authoring, migration strategies (Alembic, Liquibase, Flyway, Drizzle), query optimisation, indexing decisions, normalisation vs denormalisation trade-offs, and data-integrity constraints. Trigger phrases: "design this schema", "write a migration", "optimise this query", "model these entities", "add an index". NOT for NoSQL/document stores — use a dedicated NoSQL skill for those. NOT for ETL pipelines or data warehousing at scale — those involve different trade-offs. NOT for ORM configuration (framework setup) — this skill is about DATA SHAPE, not connection pooling or ORM bootstrap.

2026-06-0510

email-marketing

viktorbezdek/skillstack

Email content writing for newsletters, drip sequences, onboarding flows, and transactional emails. Use for newsletter drafting, automated drip sequence copy, welcome email series, subject line and preview text optimisation, re-engagement emails, and plain-language transactional email (receipts, confirmations, alerts). Trigger phrases: "write a newsletter", "draft an onboarding email sequence", "write a subject line", "write a drip campaign", "create a welcome email". NOT for email infrastructure setup (ESP config, sending domains, DKIM/DMARC) — that is a technical ops concern. NOT for social media content — use the social-media-content skill for LinkedIn or Twitter. NOT for cold outreach / sales prospecting emails — those have compliance and conversion constraints beyond marketing content.

2026-06-0510

research-synthesis

viktorbezdek/skillstack

Structured research and evidence synthesis for knowledge-intensive tasks. Use for multi-source research coordination, evidence triangulation across conflicting sources, competing-hypothesis analysis, literature/documentation sweeps, claim verification, and synthesis reports. Trigger phrases: "research this topic", "synthesise findings from", "compare sources on", "what does the evidence say about", "triangulate these claims". NOT for primary data collection (interviews, surveys) — this skill synthesises existing sources. NOT for code research or codebase exploration — use CodeGraph and Semble for that. NOT for creative content generation — synthesis produces structured analysis, not narrative content.

2026-06-0510

security-engineering

viktorbezdek/skillstack

Application security design and threat-informed engineering. Use for authentication and authorisation architecture (OAuth2, JWT, RBAC, ABAC), OWASP Top 10 vulnerability analysis, secrets management (Vault, AWS Secrets Manager, environment isolation), input validation patterns, secure API design, SQL injection and XSS prevention, and security-aware code review. Trigger phrases: "secure this endpoint", "design an auth system", "review this for security vulnerabilities", "how do I store secrets", "implement RBAC". NOT for network/infrastructure security (firewalls, VPNs, WAF config) — those belong in cloud-infrastructure. NOT for compliance auditing (SOC2, GDPR gap assessments) — that requires a compliance specialist. NOT for penetration testing or red-teaming — this skill is for defensive engineering, not offensive exercises.

Multi-domain query	Load all relevant references, synthesize

Reasoning sequence (apply to every response)

Load references/optimnow-methodology.md - use it as a reasoning lens, not a preamble
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 OptimNow tools where genuinely relevant to the problem, not as promotion

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.

Anti-Patterns

Anti-Pattern	Problem	Solution
Optimizing before allocating	Committing to discounts on unattributed spend	Get to 80%+ allocation before buying commitments
Chasing unit savings over coverage gaps	Saving $0.02/hour on 10 instances while 200 run on-demand	Prioritize commitment coverage over per-unit optimization
Ignoring spillover costs	Provisioned capacity with unchecked spillover to pay-per-token	Model total cost including spillover; set alerts
Tagging as afterthought	<60% of resources tagged, can't attribute spend	Enforce tagging via IaC; block untagged deployments
Annual commitment on new workloads	Committing before usage patterns stabilize	Start with pay-per-use; commit after 3 months of data
Single-cloud cost view	Multi-cloud spend unnormalized	Adopt FOCUS spec for cross-cloud normalization
Ignoring SaaS sprawl	Shadow IT SaaS spend exceeds infrastructure	Implement SMP; discover and rationalize SaaS portfolio
FinOps as finance-only	Engineering excluded from cost decisions	Embed FinOps in engineering workflows; distribute accountability
