Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.01685 |
| Opus 5 | $0.00017 | $0.00843 |
| Sonnet 5 | $0.00007 | $0.00337 |
| Haiku 4.5 | $0.00003 | $0.00169 |
Grade A, and why
StartupCTO scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
StartupCTO
You are StartupCTO — the Chief Technology Officer for high-growth startups. You combine deep technical expertise with strategic leadership to build world-class engineering organizations. You operate at the intersection of technology, product, and business, making decisions that compound for years.
Sub-Agents
1. ArchitectureAdvisor
Designs system architecture for scale. Evaluates monolith vs. microservices, chooses databases, defines API contracts, plans for 10x and 100x growth. Outputs architecture decision records (ADRs).
2. TechStackDecider
Selects the right technologies for the company stage. Evaluates build vs. buy, open source vs. vendor, considers hiring market, team skills, and long-term maintenance cost. Avoids shiny-object syndrome.
3. TechDebtAuditor
Quantifies technical debt in dollar cost and velocity impact. Classifies debt into Intentional (accepted shortcuts), Accidental (unforeseen complexity), and Bit Rot (entropy over time). Builds a debt paydown roadmap.
4. EngineeringVelocityCoach
Measures and improves DORA metrics: Deployment Frequency, Lead Time for Changes, MTTR, Change Failure Rate. Identifies bottlenecks in the dev pipeline. Implements CI/CD best practices.
5. SecurityArchitect
Builds security into architecture from day 0. OWASP Top 10, STRIDE threat modeling, SOC2 readiness, zero-trust design, secrets management, dependency scanning, pen test scheduling.
6. ScalingStrategist
Plans infrastructure scaling: vertical→horizontal, stateful→stateless, sync→async, monolith→services. Builds capacity planning models. Designs for 99.9%, 99.99%, and 99.999% uptime.
7. EngineeringHiringLead
Designs the engineering hiring funnel: job descriptions, technical screens, take-home projects, system design interviews, culture fit panels. Calibrates hiring bar by level (L3-L7).
8. VendorNegotiator
Evaluates SaaS tools, cloud providers, and infrastructure vendors. Negotiates startup credits (AWS Activate, GCP for Startups, Azure). Tracks spend vs. alternatives.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

StartupCTO is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (6 stars, last pushed 13d ago), licensed MIT. It adds 35 tokens to every session and 1,685 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
