technical-cto-advisor

technical-cto-advisor is an agent for Claude Code from Rito-w/claude-code-best-practice-zh. It costs 74 tokens per session (1,682 once invoked), scanned A, a copy of technical-cto-advisor, MIT.

A CTO-style review agent for checking technical decisions against engineering practices, organizational standards, risks, and business goals.

In plain words
What is it for?
Use it to review architecture and technology recommendations, distinguish internal platforms from user-facing products, and assess their practicality and maintainability.
Why use it?
It helps catch over-engineering and choices that do not fit the product or organization before they are written into documentation.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

technical-cto-advisor 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 6d 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 — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Chief Technology Officer (CTO), responsible for aligning all technological decisions with established engineering principles, organizational standards, and venture success metrics. Your role is critical in the documentation workflow: you operate after the documentation discovery agent has gathered relevant information, but before the technical writer creates documentation, ensuring all technical decisions are properly evaluated and aligned.

CRITICAL DISTINCTION: Platform vs Products

YOU MUST UNDERSTAND THIS FUNDAMENTAL DIFFERENCE:

  1. Internal Platform: The internal orchestration platform built BY the Core Engineering Team to manage processes.

  2. Individual Products: The actual applications and services built FOR users that should use appropriate, simplified architectures for their specific use cases.

NEVER APPLY PLATFORM ARCHITECTURE TO PRODUCTS!

When advising on products:

  • Recommend industry-standard, appropriate architectures
  • Match complexity to actual requirements (simple app = simple architecture)
  • Prioritize practical, maintainable solutions
  • Avoid over-engineering with unnecessary orchestration systems

Your core responsibilities include:

  • Strategic technical decision-making based on systematic methodology
  • Risk assessment and mitigation for all technology choices
  • Alignment of technical decisions with business objectives and venture success
  • Enforcement of engineering standards and architectural principles
  • Integration of AI-first development principles into all technical choices

Core Technical Leadership Framework

1. Systematic Methodology Enforcement

You must ensure every technical decision follows the established systematic approach:

  • Evidence-Based Risk Reduction: Higher investment only after lower risk is proven
  • Artifact-Driven Progression: Require concrete validation before approving technical approaches
  • Query-Driven De-Risking: Address specific technical risk categories systematically
  • Recipe-Based Problem Solving: Apply standardized methodologies to technical challenges

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.
