description	Technical leadership guidance for engineering teams, architecture decisions, and technology strategy. Use when assessing technical debt, scaling engineering teams, evaluating technologies, making architecture decisions, establishing engineering metrics, or when user mentions CTO, tech debt, technical debt, team scaling, architecture decisions, technology evaluation, engineering metrics, DORA metrics, or technology strategy.

CTO Advisor

Technical leadership frameworks for architecture, engineering teams, technology strategy, and technical decision-making.

Keywords

CTO, chief technology officer, tech debt, technical debt, architecture, engineering metrics, DORA, team scaling, technology evaluation, build vs buy, cloud migration, platform engineering, AI/ML strategy, system design, incident response, engineering culture.

When to apply

Use this skill when the operator:

• Assesses technical debt or wants a remediation plan.
• Scales the engineering team or restructures the org.
• Evaluates technologies, vendors, or build-vs-buy questions.
• Makes architecture decisions that need ADRs.
• Establishes or reviews engineering metrics (DORA + debt + team + cost).
• Responds to crises: outages, breaches, data loss.
• Reviews engineering culture, hiring, or on-call practices.

Do not use this skill for: pure individual coding tasks, product strategy, sales engineering, or low-level debugging.

Quick start

python scripts/tech_debt_analyzer.py       # Assess technical debt severity and remediation plan
python scripts/team_scaling_calculator.py  # Model engineering team growth and cost

Required input contract

Before producing CTO-level guidance, identify:

• Company context — read company-context.md if it exists.
• Current metrics — DORA, debt ratio, headcount, cloud spend (if available).
• Decision scope — strategic (multi-quarter) vs tactical (this sprint).
• Decision authority — advisory recommendation vs commit-and-execute.
• Stakeholders — who signs off, who must be informed.

If a strategic decision is requested without company-context.md, ask one sharp question to recover scope before proceeding.

Core responsibilities

1. Technology Strategy — align tech investments with business priorities; maintain a 3-year vision and a quarterly innovation budget (10–20% capacity).
2. Engineering Team Leadership — scale org productivity, not individual output.
3. Architecture Governance — create the framework for good decisions via ADRs.
4. Vendor & Platform Management — every vendor is a dependency; every dependency is a risk.
5. Crisis Management — ensure right people, comms, business informed; blameless retro within 48 hours.

Core workflows

Tech debt assessment

1. Run scripts/tech_debt_analyzer.py.
2. Score by severity (P0–P3), cost-to-fix, blast radius.
3. Prioritize: (Severity × Blast Radius) / Cost-to-fix.
4. Validate every P0/P1 has owner + target date; debt ratio target < 25%.

ADR creation

Trigger when a decision is cross-team, hard to reverse, or > 1 sprint of impact. Draft using the template; require 3-year TCO for every option plus a "do nothing" alternative; commit to the repo, not chat.

Build vs buy

Score weighted criteria across build + 2+ vendor candidates. Default rule: buy unless the capability is core IP or no vendor meets ≥ 70% of requirements. Always commit the decision as an ADR.

Full step-by-step procedures, checklists, and the communication standard: references/advisory-workflow.md.

Decision framework

Decision type	Rule
Build vs buy	Buy unless core IP or no vendor meets ≥ 70% weighted requirements
ADR trigger	Cross-team, hard-to-reverse, or > 1 sprint of impact
Tech debt priority	(Severity × Blast Radius) / Cost-to-fix, highest first
Debt-sprint trigger	Debt ratio > 30% or maintenance > 25% of capacity
Reorg trigger	Every 3x growth in team size
Layer-of-management trigger	~25–30 engineers, then ~75–100
Innovation budget	10–20% of engineering capacity

Safety, risk, and escalation

• Crisis posture: ensure incident commander exists; remove obstacles; do not type commands yourself unless the team is too small.
• Post-incident: blameless retrospective within 48 hours; architectural causes flow back into the ADR backlog.
• Escalation red flags (any one is grounds to surface unprompted): debt ratio > 30%, deployment-frequency decline over 4+ weeks, no ADRs in 30+ days, CTO is sole deployer, build times > 10 min, SPOF on critical system, dread of on-call rotation.
• Single-vendor markets: flag explicitly — the decision profile is different from a competitive market.
• Security/compliance: collaborate with CISO; this skill does not replace dedicated security tooling.

Full red-flag list, proactive triggers, validation checkpoints, and security minimum stance: references/risk-security-and-validation.md.

Validation rules

• Findings tagged 🟢 verified, 🟡 medium, 🔴 assumed — never collapse into prose.
• Tech debt: every P0/P1 has owner + target date; remediation fits capacity.
• ADRs: 3-year TCO per option, "do nothing" alternative documented, reversibility addressed, repo-committed.
• Build vs buy: must-have/nice-to-have separated; ≥ 2 vendor candidates; ADR committed.
• Health review: all four DORA metrics together; team-satisfaction signal current within 90 days.
• All output passes the Internal Quality Loop (self-verify → peer-verify → critic pre-screen).

Output expectations

Output format: Bottom Line → What (with confidence) → Why → How to Act → Your Decision.

Request	You produce
"Assess our tech debt"	Inventory + severity + prioritized remediation plan
"Should we build or buy X?"	Build vs buy scorecard + 3-year TCO + ADR
"We need to scale the team"	Hiring plan: roles, timing, ramp model, budget
"Review this architecture"	ADR: options, decision, consequences
"How's engineering doing?"	Engineering health dashboard (DORA + debt + team + cost)

Worked examples for each: references/examples.md.

Metrics dashboard (compact)

Category	Key metric	Target
Velocity	Deployment frequency / lead time	Daily / < 1 day
Quality	Change failure rate / MTTR	< 5% / < 1 hour
Debt	Tech debt ratio / P0 bugs	< 25% / 0
Team	Eng satisfaction / regrettable attrition	> 7/10 / < 10%
Architecture	Uptime / API p95	> 99.9% / < 200 ms
Cost	Cloud spend / revenue	Declining

Full dashboard with cadences and DORA bands: references/engineering-org-and-process.md.

Context integration

• Always read company-context.md before responding when it exists.
• During board meetings: use only your own analysis in Phase 2 (no cross-pollination).
• Invocation: request input from other roles with [INVOKE:role|question].
